| 3 | * check/Makefile.am, check/lightning.c: Add new hmul tests. |
| 4 | * doc/body.texi: Document hmul. |
| 5 | * include/lightning.h.in: Create the new hmul codes. |

| 11 | lib/jit_loongarch-cpu.c, lib/jit_loongarch-sz.c, lib/jit_loongarch.c, |
| 12 | lib/jit_mips-cpu.c, lib/jit_mips-sz.c, lib/jit_mips.c, |
| 13 | lib/jit_ppc-cpu.c, lib/jit_ppc-sz.c, lib/jit_ppc.c, |
| 14 | lib/jit_riscv-cpu.c, lib/jit_riscv-sz.c, lib/jit_riscv.c, |
| 15 | lib/jit_s390-cpu.c, lib/jit_s390-sz.c, lib/jit_s390.c, |
| 16 | lib/jit_sparc-cpu.c, lib/jit_sparc-sz.c, lib/jit_sparc.c, |
| 17 | lib/jit_x86-cpu.c, lib/jit_x86-sz.c, lib/jit_x86.c: Implement |
| 18 | hmul and update the *-sz.c files. |

| 31 | * lib/lightning.c: Add logic for the new register pair in the |
| 32 | 'v' (second) field of jit_node_t. The new pattern is required |
| 33 | to allow having a 'double' immediate in the last argument, for |
| 34 | the versions with immediates. The versions with immediates are |
| 35 | added for consistency, as they should be very rarely used in |
| 36 | common usage of fused multiply add/sub. |
| 37 | |
| 38 | 2023-04-06 Paulo Andrade <pcpa@gnu.org> |
| 39 | |
| 40 | * include/lightning.h.in: Define new movi_w_f, movi_w_d and |
| 41 | movi_ww_d instructions, to have an inverse counterpart to |
| 42 | movi_f_w, movi_d_w and movi_d_ww. |
| 43 | * lib/lightning.c: Update for the new instructions. |
| 44 | * lib/jit_names.c, lib/jit_print.c: Update debug information. |
| 45 | |
| 46 | 2023-04-05 Paulo Andrade <pcpa@gnu.org> |
| 47 | |
| 48 | * include/lightning.h.in: Define new unldr, unldi, unldr_x, |
| 49 | unldi_x, unstr, unsti, unldr_x and unstr_x instructions. |
| 50 | Remove comment about internal backend specific codes, as they |
| 51 | are required by unldr_x and unstr_x in some code paths. |
| 52 | * lib/lightning.c: Implement generic movi_f_w, movi_d_w and |
| 53 | movi_d_ww that are actually the same for all ports. |
| 54 | Define generic load/store implementations when unaligned memory |
| 55 | access does not trap. |

| 64 | instructions with two outputs. |
| 65 | |
| 66 | 2023-03-20 Paulo Andrade <pcpa@gnu.org> |
| 67 | |
| 68 | * check/all.tst: Add missing instructions to debug encoding. |
| 69 | * check/lightning.c: Implement calls to the new rich set of |
| 70 | instructions, with an immediate argument, mostly which are resolved |
| 71 | at code generation time. With the exception of jit_negi_{f,d}, |
| 72 | jit_absi{f,d} and jit_sqrti_{f,d} that generate code to execute at |
| 73 | runtime. This is required because the code generator should create |
| 74 | the proper float environment with rounding modes, exceptions, etc. |
| 75 | The new jit_depi is just a wrapper to have the second operand as an |
| 76 | immediate and call jit_depr. |
| 77 | * include/lightning.h.in: Declare new instructions code and function |
| 78 | prototypes as appropriate. |
| 79 | * include/lightning/jit_private.h: Add 4 new macros to generate |
| 80 | synthetic debug for float operations with an immediate argument. |

| 84 | Add code to call the generic code to implement new instructions |
| 85 | with immediate operands. |
| 86 | * lib/jit_names.c, lib/jit_print.c: Add debug for the new instructions |
| 87 | with immediate operands. |
| 88 | * lib/lightning.c: Add code to handle regsets and actually implement |
| 89 | the generic new instructions. |
| 90 | |
| 91 | 2023-03-17 Paulo Andrade <pcpa@gnu.org> |

| 96 | and update regsets as appropriate. |
| 97 | * lib/jit_names.c, lib/jit_print.c: Update for debug information |
| 98 | of ext, ext_u and dep. |
| 99 | * include/lightning.h.in: Define jit_code_t for ext, ext_u and dep. |
| 100 | * check/lightning.c: Handle the new instructions. |
| 101 | * check/all.tst: Add new instructions for the full disassembly. |
| 102 | |
| 103 | 2023-03-07 Paulo Andrade <pcpa@gnu.org> |

| 111 | lib/jit_arm.c: Implement optimized rrotr and rroti. lrotr and |
| 112 | lroti just adjust parameters for a left shift rotate. |
| 113 | * lib/jit_alpha-cpu.c, lib/jit_alpha.c, lib/jit_ia64-cpu, |
| 114 | lib/jit_ia64.c, lib/jit_riscv-cpu.c, lib/jit_riscv.c, |
| 115 | jit_sparc-cpu.c, jit_sparc.c: Implement calls to fallback lrotr, |
| 116 | lroti, rrotr and rroti. |
| 117 | * lib/jit_hppa-cpu.c, lib/jit_hppa.c: Implement optimized rroti. |
| 118 | Other instructions use fallbacks. |
| 119 | * lib/jit_loongarch-cpu.c, lib/jit_loongarch.c: Implement optimized |
| 120 | rrotr and rroti. lrotr and lroti just adapt arguments and use a |
| 121 | right shift. |
| 122 | * lib/jit_mips-cpu.c, lib/jit_mips.c: If mips2, Implement optimized |
| 123 | rrotr and rroti. lrotr and lroti just adapt arguments and use a |

| 126 | lib/jit_x86-cpu.c, lib/jit_x86.c: Implement optimized lrotr, |
| 127 | lroti, rrotr, rroti. |
| 128 | * lib/jit_fallback.c: Implement fallbacks for lrotr, lroti, |
| 129 | rrotr and rroti. Also add extra macro to avoid segfaults in s390, |
| 130 | that cannot use register zero for some addressing instructions. |
| 131 | |
| 132 | 2023-03-02 Paulo Andrade <pcpa@gnu.org> |
| 133 | |
| 134 | * check/popcnt.tst, check/popcnt.ok: New test files for the new |
| 135 | popcntr instruction. |

| 139 | popcntr using the fpu. |
| 140 | * lib/jit_alpha-cpu.c, lib/jit_alpha.c: Implement optimized |
| 141 | popcntr using the ctpop instruction. |
| 142 | * lib/jit_arm-vfp.c, lib/jit_arm-cpu.c, lib/jit_arm.c: Implement |
| 143 | untested optimized popcntr using vfp >= 4, otherwise use a |
| 144 | software fallback. |
| 145 | * lib/jit_ia64-cpu.c, lib/jit_jia64.c: Implement optimized |
| 146 | popcntr using the popcnt instruction. |

| 155 | popcnt. |
| 156 | |
| 157 | 2023-02-26 Paulo Andrade <pcpa@gnu.org> |
| 158 | |
| 159 | * check/bit.tst: Correct 32 bit sample ctz implementation. |
| 160 | * include/lightning/jit_mips.h: Add jit_cpu flags for instructions |
| 161 | that cannot be used in delay slot. |
| 162 | * lib/jit_fallback.c: Mips fallbacks now might need a flush of |
| 163 | instructions to get correct label addresses, due to pending |
| 164 | instruction candidate to delay slot. |
| 165 | * lib/jit_mips-cpu.c: Flush any pending instruction if it cannot |
| 166 | be used in the delay slot. Add calls to fallback clo, clz, cto and |
| 167 | ctz for mips 1. |
| 168 | * lib/jit_mips.c: Add code to set defaults or detect if can use |
| 169 | certain instructions to delay slots. |
| 170 | |
| 171 | 2023-02-23 Paulo Andrade <pcpa@gnu.org> |
| 172 | |
| 173 | * include/lightning/jit_private.h: Add new 'inst' field to |
| 174 | jit_compiler_t, if __mips__ is defined. This field is a simple |
| 175 | helper for a pending instruction to be emitted, and that can |
| 176 | be emitted out of order. |
| 177 | * lib/jit_fallback.c: Update for changes in internal mips patching |
| 178 | and jumping macros and function calls. |
| 179 | * lib/jit_mips-cpu.c: Core of changes to attempt to fill delay |
| 180 | slots with instructions that can be emitted out of order. |

| 183 | |
| 184 | 2023-02-20 Paulo Andrade <pcpa@gnu.org> |
| 185 | |
| 186 | * check/float.tst: Add conditionals for mips release for expected |
| 187 | NaN truncated to an integer. |
| 188 | * check/lightning.c: Add extra preprocessor for mips release. |
| 189 | * include/lightning/jit_mips.h: Make the NEW_ABI preprocessor |
| 190 | defined to zero if using the n32 or n64 abis. This makes it |
| 191 | easier to create runtime checks with an always true or false |
| 192 | condition. |
| 193 | * lib/jit_mips-cpu.c, lib/jit_mips-fpu.c: Implement mips release |
| 194 | 6 support. |
| 195 | * lib/jit_mips.c: Add more reliable mips release detection code. |
| 196 | |
| 197 | 2023-02-09 Paulo Andrade <pcpa@gnu.org> |
| 198 | |
| 199 | * check/Makefile.am: Update for new bit.tst test, to check the |
| 200 | new clor, clzr, ctor and ctzr instructions. |
| 201 | * check/all.tst: Update to verify encoding of new instructions. |
| 202 | * check/lightning.c: Update to have the lightning "assembler" |

| 207 | lib/jit_riscv.c, lib/jit_s390.c, lib/jit_sparc.c, lib/jit_x86.c: |
| 208 | Implement fallback version of new instructions. |
| 209 | * lib/jit_fallback.c: Actual implementation of the fallbacks of |
| 210 | the new instructions. |
| 211 | * lib/jit_names.c: Update to print debug information of new |
| 212 | instructions. |
| 213 | |
| 214 | 2023-01-26 Paulo Andrade <pcpa@gnu.org> |
| 215 | |
| 216 | * check/riprel.c, check/riprel.ok: New check files. |
| 217 | * check/Makefile.am: Support for new riprel test. |
| 218 | * lib/jit_x86-cpu.c, lib/jit_x86-sse.c, lib/jit_x86.c: Implement |
| 219 | %rip relative addressing when reliable. Currently disabled for |
| 220 | x32 and _WIN32; could be added for positive relative addresses |
| 221 | only where it should work. |
| 222 | * lib/lightning.c: Correct problem added in previous patch due |
| 223 | to not testing on a 32 bit environment. |
| 224 | |
| 225 | 2023-01-23 Paulo Andrade <pcpa@gnu.org> |
| 226 | |
| 227 | * lib/jit_mips-cpu.c, lib/jit_mips-cpu.c: Use pseudo instructions |
| 228 | "b" (BEQ(0,0,disp)) and "bal" (BGEZAL(0,disp)) for mips2, when an |
| 229 | unconditional branch or function call is known to be in range of a |
| 230 | relative jump. This should significantly reduce jit size generation. |
| 231 | |
| 232 | 2023-01-20 Paulo Andrade <pcpa@gnu.org> |
| 233 | |
| 234 | * lib/jit_mips-cpu.c, lib/jit_mips.c, lib/jit_rewind.c: Adapt |
| 235 | code to implement a variable framesize and optimize frame pointer |
| 236 | for simple leaf functions. |
| 237 | |
| 238 | 2023-01-19 Paulo Andrade <pcpa@gnu.org> |
| 239 | |
| 240 | * lib/jit_riscv.c, lib/jit_riscv-cpu.c: Adapt code to use a |
| 241 | variable framesize. Previously it was aligning the stack at |
| 242 | 8 bytes, not 16. Now functions are called with a 16 byte aligned |
| 243 | stack. |
| 244 | |
| 245 | 2023-01-18 Paulo Andrade <pcpa@gnu.org> |
| 246 | |
| 247 | * include/lightning/jit_private.h: Include new framesize field |
| 248 | of jit_compiler_t; add new alist field for jit_function_t; add |
| 249 | new cvt_offset and need_stack fields specific to x86. |
| 250 | * lib/jit_x86.c, lib/jit_x86-cpu: Rewrite code to create stack |
| 251 | frames, so that less stack space can be used if no, or very few |
| 252 | callee save registers are modified in a function. |
| 253 | * jit_x86-sse.c, jit_x86-x87.c: Make CVT_OFFSET variable, and |
| 254 | dynamically allocated; this is required to avoid needing to |
| 255 | modify twice %rsp at function prologs, even if no stack space |
| 256 | is used. |
| 257 | |
| 258 | 2022-11-09 Paulo Andrade <pcpa@gnu.org> |
| 259 | |
| 260 | * configure.ac: Add new --enable-devel-strong-type-checking |
| 261 | option. |
| 262 | * include/lightning.h.in: Rework to not need to know if |
| 263 | PACKED_STACK is defined, and add a new argument to _jit_arg, |
| 264 | _jit_putarg{r,i}, _jit_pusharg{r,i} and _jit_ret{r,i} to have |
| 265 | the same code path if PACKED_STACK is defined or not, and also |
| 266 | to implement STRONG_TYPE_CHECK enabled with the new |
| 267 | --enable-devel-strong-type-checking. |
| 268 | * include/lightning/jit_private.h: Add new macros to add assertions |
| 269 | for STRONG_TYPE_CHECK and avoid pasting tokens in jit_inc_synth* |
| 270 | when the token is not a static known value. |
| 271 | * lib/jit_aarch64.c: The first implementation of the new code, |
| 272 | working correctly in Apple M1 and with and without STRONG_TYPE_CHECK |
| 273 | in Linux. |
| 274 | |
| 275 | 2022-11-08 Paulo Andrade <pcpa@gnu.org> |
| 276 | |
| 277 | Add support for packed stack arguments as used by Apple M1 |
| 278 | aarch64 cpus. This requires a major redesign in how Lightning |
| 279 | works, because contrary to all other supported ports, in this |
| 280 | case arguments must be truncated and sign/zero extended if |
| 281 | passed in registers, but when receiving the argument, there |
| 282 | is no need to truncate and sign/zero extend. |
| 283 | Return values are also treated this way. The callee must |
| 284 | truncate sign/zero extend, not the caller. |
| 285 | check/Makefile.am: Add LIGHTNING_CFLAGS to AM_CFLAGS. |
| 286 | check/all.tst: Implement paired arg/getarg/pusharg/putarg/ret |
| 287 | codes to validate they do not generate assertions. |
| 288 | * check/allocar.tst, check/call.tst, check/fib.tst, check/put.tst, |
| 289 | check/stack.tst: Update to pass in all build types. |
| 290 | check/lightning.c: Add new codes for extra codes to handle |
| 291 | packed stack. |
| 292 | * configure.ac: Add a preprocessor define to know if packed stack |
| 293 | need is required. This is not really used, as it was moved to |
| 294 | jit_aarch64.h. |
| 295 | * doc/Makefile.am: Add LIGHTNING_CFLAGS to AM_CFLAGS. |
| 296 | * doc/rpn.c: Update to pass in all build types. |
| 297 | include/lightning.h.in: Add new codes and reorder enum. |
| 298 | * include/lightning/jit_aarch64.h: Detect condition of needing |
| 299 | a packed stack. |
| 300 | * lib/jit_aarch64-sz.c: Regenerate. |
| 301 | * lib/jit_aarch64.c: Major updates for packed stack. |
| 302 | * lib/jit_names.c: Updates for debug output. |
| 303 | * lib/lightning.c: Update for new codes. |
| 304 | |

| 353 | * include/lightning/jit_private.h: Add a field to store the size |
| 354 | of the protected memory. |
| 355 | * lib/lightning.c: Remember the size of the protected memory and |
| 356 | implement the two new functions. |
| 357 | |
| 358 | 2022-10-12 Paulo Andrade <pcpa@gnu.org> |
| 359 | |
| 360 | * include/lightning/jit_loongarch.h, lib/jit_loongarch-cpu.c, |
| 361 | lib/jit_loongarch-fpu.c, lib/jit_loongarch-sz.c, lib/jit_loongarch.c: |
| 362 | New files implementing the first version of the new loongarch port. |
| 363 | * check/float.tst: Add preprocessor checks for NaN and +-Inf |
| 364 | values converted to integers for loongarch. |
| 365 | * configure.ac: Add check and conditionals for new architecture. |
| 366 | * include/lightning.h.in, check/lightning.c, |
| 367 | include/lightning/Makefile.am, include/lightning/jit_private.h, |
| 368 | lib/Makefile.am, lib/jit_size.c, lib/lightning.c: Update for new |
| 369 | port. |
| 370 | |
| 371 | 2022-10-05 Paulo Andrade <pcpa@gnu.org> |
| 372 | |
| 373 | * check/lightning.c: Remove -Dmacro=value from usage and attempt |
| 374 | to parse it. It was buggy and not properly implemented. Now |
| 375 | it pass any extra options to the generated jit. To pass any |
| 376 | option starting with '-' need to also use '--'. |
| 377 | * check/collatz.e: New sample file showing an example of jit |
| 378 | generation. |
| 379 | |
| 380 | 2022-10-04 Paulo Andrade <pcpa@gnu.org> |
| 381 | |
| 382 | * include/lightning/jit_private.h: Add new flag to jit_block_t. |
| 383 | * lib/lightning.c: Rewrite register liveness and state at block |
| 384 | entry code to avoid a very expensive and non scaling code path. |
| 385 | Now it attempts to do as few as possible recomputations when |
| 386 | merging state of adjacent blocks, still doing one extra nop pass |
| 387 | (in the sense that it will not find any changes) to make sure the |
| 388 | logic is correct. |
| 389 | |
| 390 | 2022-09-30 Paulo Andrade <pcpa@gnu.org> |
| 391 | |
| 392 | * include/lightning/jit_private.h: Implement new data structures |
| 393 | specific to riscv. |
| 394 | * lib/jit_disasm.c: Extra disassemble code for riscv constant pool. |
| 395 | * lib/jit_riscv-cpu.c: Modify movi to use constant pool if 3 or |
| 396 | more instructions are required to construct constant and modify |
| 397 | movi_p to use a pc relative load from a constant pool. |
| 398 | lib/jit_riscv-sz.c: Update for new constant pool code. Most |
| 399 | instructions that need 64 bit constants are significantly reduced. |
| 400 | * lib/jit_riscv.c: Implement most of the constant pool code. |
| 401 | * lib/jit_size.c: Update for estimate of code generation size. |
| 402 | * lib/lightning.c: Update for riscv specific code, and also make |
| 403 | sure to mprotect the constant pool as executable. |
| 404 | |
| 405 | 2022-09-08 Paulo Andrade <pcpa@gnu.org> |
| 406 | |
| 407 | * lib/jit_fallback.c: Implement fallback compare and swap with |
| 408 | pthreads. |
| 409 | * check/Makefile.am: Update for new cas{r,i} simple test. |
| 410 | * check/catomic.c, check/catomic.ok: New test case for |
| 411 | simple compare and swap atomic operation. |
| 412 | * check/lightning.c: Add entries to be able to use |
| 413 | the new compare and swap atomic operation. Still missing |
| 414 | a general test, only the basic C version. |
| 415 | * include/lightning.h.in: Include pthread.h, even if not |
| 416 | needing a fallback compare and swap. |
| 417 | * include/lightning/jit_private.h: Add support for a register pair |
| 418 | in second argument. Required by the new casr and casi operations. |
| 419 | * lib/jit_aarch64-cpu.c, lib/jit_aarch64-sz.c, lib/jit_aarch64.c, |
| 420 | lib/jit_ppc-cpu.c, lib/jit_ppc-sz.c, lib/jit_ppc.c, lib/jit_x86-cpu.c, |
| 421 | lib/jit_x86-sz.c, lib/jit_x86.c: Implement inline code for compare |
| 422 | and swap. |
| 423 | * lib/jit_arm-cpu.c, lib/jit_arm-sz.c, lib/jit_arm.c: Implement |
| 424 | inline code for compare and swap if cpu is armv7, otherwise, use |
| 425 | a fallback with pthreads. |
| 426 | * lib/jit_alpha-cpu.c, lib/jit_alpha-sz.c, lib/jit_alpha.c, |
| 427 | lib/jit_hppa-cpu.c, lib/jit_hppa-sz.c, lib/jit_hppa.c, |

| 431 | lib/jit_s390-cpu.c, lib/jit_s390-sz.c, lib/jit_s390.c, |
| 432 | lib/jit_sparc-cpu.c, lib/jit_sparc-sz.c, lib/jit_sparc.c: Implement |
| 433 | fallback compare and swap with pthreads. At least some of these |
| 434 | should be updated for inline code generation. |
| 435 | * lib/jit_names.c, lib/jit_print.c: lib/lightning.c: Update for the |
| 436 | new compare and swap operation. |
| 437 | * doc/body.texi: Add simple documentation of the compare and swap |
| 438 | new operation. |
| 439 | |
| 440 | 2022-08-12 Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de> |
| 441 | |
| 442 | Document jit_align. |
| 443 | * doc/body.texi: Add documentation for jit_align. |
| 444 | |
| 445 | 2022-05-14 Paulo Andrade <pcpa@gnu.org> |
| 446 | |
| 447 | * include/lightning.h.in: Reorder jit_mov{n,z}r in instruction list. |
| 448 | * lib/jit_alpha.c, lib/jit_alpha-cpu.c, lib/jit_hppa.c, |
| 449 | lib/jit_hppa-cpu.c, lib/jit_ia64.c, lib/jit_ia64-cpu.c, |
| 450 | lib/jit_riscv.c, lib/jit_riscv-cpu.c, lib/jit_s390.c, |
| 451 | lib/jit_s390-cpu.c, lib/jit_sparc.c, lib/jit_sparc-cpu.c: |
| 452 | Implement fallback jit_mov{n,z}r. These are a somewhat cheap |
| 453 | implementation, but should be reviewed for the arches that already |
| 454 | have a proper conditional move. |
| 455 | * lib/jit_arm-sz.c, lib/jit_mips-sz.c: Add missing maximum size |
| 456 | estimative and reorder. |
| 457 | * lib/jit_aarch64-sz.c, lib/jit_x86-sz.c, lib/jit_ppc-sz.c: |
| 458 | Reorder entry to match definition order. |
| 459 | * lib/jit_aarch64-sz.c, lib/jit_alpha-sz.c, lib/jit_hppa-sz.c, |
| 460 | lib/jit_ia64-sz.c, lib/jit_riscv-sz.c, lib/jit_s390-sz.c, |
| 461 | lib/jit_sparc-sz.c: Add heuristic value, basically the sum of |
| 462 | the cost of a movr + beqr. |
| 463 | * lib/jit_names.c: Add entries for debug output of mov{n,z}r. |
| 464 | * lib/lightning.c: Use proper bitmask in jit_classify. |
| 465 | |
| 466 | 2021-04-03 Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de> |
| 467 | |
| 468 | * check/Makefile.am: Add test for the live instruction. |
| 469 | * check/live.ok: New file. |
| 470 | * check/live.tst: New file. |
| 471 | * doc/body.texi: Add documentation for the live instruction and |
| 472 | for jit_get_reg/jit_get_unreg. Fix menu entries. |
| 473 | * include/lightning.h.in (jit_get_reg, jit_unget_reg): Expose the |
| 474 | macros in the public header file. |
| 475 | * include/lightning/jit_private.h (jit_get_reg, jit_unget_reg): |
| 476 | Remove the macros from the private header file. |
| 477 | |
| 478 | 2021-04-03 Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de> |
| 479 | |
| 480 | * Makefile.am, check/Makefile.am, doc/Makefile.am, |
| 481 | lib/Makefile.am: Include $(top_builddir)/include in include paths |
| 482 | for the autoconf-generated header file lightning.h. |
| 483 | |
| 484 | 2021-04-03 Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de> |
| 485 | |
| 486 | * doc/.gitignore: Add version.texi to list of ignored files. |
| 487 | * doc/version.texi: Remove file from version control. |
| 488 | |
| 489 | 2020-18-04 Paulo Andrade <pcpa@gnu.org> |
| 490 | |
| 491 | * lib/jit_x86-cpu.c, lib/jit_x86.c: Implement %rip relative |
| 492 | calls and jumps on x86_64. Currently very conservative, assuming |
| 493 | a jit block can be larger than 2G, so, if a jump or call is in |
| 494 | the same jit generation, but target is unknown, use an indirect |
| 495 | branch (could have an option to assume a jit code block is |
| 496 | never larger than 2G). Also a deoptimization is that now does |
| 497 | not always generate ip relative jmpi; previously implicitly |
| 498 | assumed jmpi would never be larger than 2G. Overall still an |
| 499 | optimization. |
| 500 | |
| 501 | 2020-23-01 Paulo Andrade <pcpa@gnu.org> |
| 502 | |
| 503 | * lib/lightning.c: Add a proper fix to the condition of considering |
| 504 | a register dead at entry of a block when it modifies the register |
| 505 | !after! a branch to a target where it is live. |
| 506 | The correction is just to split blocks on branches. It uses an |
| 507 | extra label per branch, but makes following the code simpler and |
| 508 | avoid costly searches. |
| 509 | |
| 510 | 2020-22-01 Paulo Andrade <pcpa@gnu.org> |
| 511 | |
| 512 | * lib/lightning.c: Correct a special condition of a register |
| 513 | only assigned in a block, and incorrectly marked as dead before |
| 514 | a jump where the register is live. |
| 515 | |
| 516 | 2019-10-04 Paulo Andrade <pcpa@gnu.org> |
| 517 | |
| 518 | * check/lightning.c, include/lightning/jit_private.h, |
| 519 | include/lightning/jit_x86.h, lib/jit_x86-cpu.c, lib/jit_x86-sz.c, |
| 520 | lib/jit_x86.c: Correct issues with MinGW64 that defines _WIN32 |
| 521 | and needs long long for jit_word_t. |
| 522 | |
| 523 | 2019-09-16 Paulo Andrade <pcpa@gnu.org> |
| 524 | |
| 525 | * lib/lightning.c: Do not add registers that are never modified |
| 526 | to the set of registers to scan for live range, what might |
| 527 | consume a lot of cpu time, doing nothing. |
| 528 | |
| 529 | 2019-09-16 Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de> |
| 530 | |
| 531 | * include/lightning/jit_x86.h, lib/jit_x86.c: Correct x86_64 |
| 532 | backend, made %r12 a callee-save register as dictated by the |
| 533 | System V AMD64 ABI. |
| 534 | |
| 535 | 2019-09-16 Paulo Andrade <pcpa@gnu.org> |
| 536 | |
| 537 | * Makefile.am: Do not force CFLAGS for the get_jit_size target. |
| 538 | * check/lightning.c: Drop __ppc__ check. |
| 539 | * include/lightning.h.in: Drop __ppc__ check. Add new |
| 540 | jit_flag_vararg flag, for special case in powerpc 32 bit using |
| 541 | the SYSV abi, and need to pass an extra argument during code |
| 542 | generation. |
| 543 | * include/lightning/jit_ppc.c: Drop __ppc_ check. Remove the |
| 544 | ABI_ELFv2 macro, as it now directly checks for the _CALL_ELF |
| 545 | value when/if appropriate. |
| 546 | * include/lightning/jit_private.h: Drop __ppc_ check. Check for |
| 547 | _CALL_AIXDESC to define extra data to handle function |
| 548 | descriptors. |
| 549 | * lib/jit_ppc-cpu.c: Update to check for _CALL_SYSV; assume |
| 550 | !_CALL_SYSV == (_CALL_AIX || _CALL_LINUX). Significant code |
| 551 | rework for the SYSV abi. |
| 552 | * lib/jit_ppc-sz.c: Update for the SYSV abi. |
| 553 | * lib/jit_ppc.c: Update for the SYSV abi. Add matching va_list |
| 554 | type. Drop __ppc__ check. |
| 555 | * lib/jit_size.c: Drop __ppc_ check. |
| 556 | * lib/lightning.c: Drop __ppc__ check. Add proper check for |
| 557 | __powerpc__ and _CALL_AIXDESC to manage function descriptors. |
| 558 | * lib/size.c: Update to drop __pppc_ check and SYSV abi. |
| 559 | |
| 560 | 2019-08-30 Paulo Andrade <pcpa@gnu.org> |
| 561 | |
| 562 | * lib/jit_mips-cpu.c: Use JALR to get the same effect as JR, as |
| 563 | in mips32r6 JR generates an illegal instruction. Thanks to |
| 564 | Bruno Haible for providing a patch and the information, reported at |
| 565 | https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=925129 |
| 566 | * THANKS: update. |
| 567 | |
| 568 | 2019-08-29 Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de> |
| 569 | |
| 570 | * include/lightning/jit_private.h: Move definition of offsetof |
| 571 | from the public header file here. |
| 572 | |
| 573 | * configure.ac, include/Makefile.am, include/lightning.h, |
| 574 | include/lightning.h.in: Generate lightning.h from lightning.in.h |
| 575 | and remove the dependence on config.h from the public header file. |
| 576 | |
| 577 | 2019-06-04 Paulo Andrade <pcpa@gnu.org> |
| 578 | |
| 579 | * include/lightning/jit_riscv.h, lib/jit_riscv-cpu.c, |
| 580 | lib/jit_riscv-fpu.c, lib/jit_riscv-sz.c, lib/jit_riscv.c: |
| 581 | Implement riscv port. Only 64 bit Linux supported. Built on |
| 582 | Fedora 28 image. |
| 583 | |
| 584 | * check/all.tst, check/float.tst, configure.ac, include/lightning.h, |
| 585 | include/lightning/Makefile.am, include/lightning/jit_private.h, |
| 586 | lib/Makefile.am, lib/jit_disasm.c, lib/jit_size.c, lib/lightning.c: |
| 587 | Minor updates for the new riscv port. |
| 588 | |
| 589 | 2019-06-04 Paulo Andrade <pcpa@gnu.org> |
| 590 | |
| 591 | * lib/jit_alpha.c lib/jit_ia64.c lib/jit_mips.c lib/jit_sparc.c: |
| 592 | Correct assertion of _jitc->regarg after emiting an instruction. |
| 593 | jit_carry may be set, but not an argument to the current instruction. |
| 594 | |
| 595 | 2019-06-01 Paulo Andrade <pcpa@gnu.org> |
| 596 | |
| 597 | * lib/lightning.c: Correct assertion on jit_unget_reg when the |
| 598 | argument is jit_carry, and jit_carry was not used in the |
| 599 | instruction. |
| 600 | |
| 601 | 2019-06-01 Paulo Andrade <pcpa@gnu.org> |
| 602 | |
| 603 | * include/lightning/jit_private.h: Remove no longer need |
| 604 | setmask field of jit_block_t and blockmask from jit_compiler_t. |
| 605 | |
| 606 | * lib/lightning.c: Rework of register live and unknown state |
| 607 | information during jit generation. It no longer recurses nor |
| 608 | do dangerous bit unset of registers in unknown state. The |
| 609 | only pitfall known, that must be taken care now is that jmpr |
| 610 | (or jmpi to not a jit node) is treated as a function call, as |
| 611 | otherwise it would need to consider all registers live, and |
| 612 | spill/reload during all jit generation. |
| 613 | |
| 614 | 2018-12-28 Paulo Andrade <pcpa@gnu.org> |
| 615 | |
| 616 | * lib/jit_disasm.c: Release bfd handle. Thanks for patch to |
| 617 | Marc Nieper-Wißkirchen. |
| 618 | |
| 619 | 2018-08-30 Paulo Andrade <pcpa@gnu.org> |
| 620 | |
| 621 | * lib/jit_disasm.c: Add hints to select hppa disassembler. |
| 622 | |
| 623 | * lib/jit_hppa-cpu.c: Correct address of vastart when all |
| 624 | argument registers were used as non vararg arguments. |
| 625 | |
| 626 | * lib/jit_hppa-fpu.c: Disable load/store of rv,ix,rb where |
| 627 | rv is the value, ix is an register or integer offset and rb |
| 628 | is a base register. These should be better tested, as they do |
| 629 | not work on all environments (fail on qemu-hppa). |
| 630 | |
| 631 | 2018-04-20 Paulo Andrade <pcpa@gnu.org> |
| 632 | |
| 633 | * include/lightning/jit_private.h: Add new register classes to |
| 634 | flag float registers and double only registers, required for sparc64 |
| 635 | where only low 32 bit fpr registers can be used for single precision |
| 636 | operations. |
| 637 | Add new 128 bit jit_regset_t type for sparc64 register set. |
| 638 | |
| 639 | * include/lightning/jit_sparc.h, lib/jit_sparc-cpu.c, lib/jit_sparc-fpu.c, |
| 640 | lib/jit_sparc-sz.c, lib/jit_sparc.c: Update for 64 bits sparc. |
| 641 | |
| 642 | * lib/lightning.c: Update for new jit_regset_t required for sparc64. |
| 643 | |
| 644 | 2018-02-26 Paulo Andrade <pcpa@gnu.org> |
| 645 | |
| 646 | * check/lightning.c, include/lightning.h: Add the new jit_va_push |
| 647 | interface. That should be called when passing a va_list to a C |
| 648 | function. This is required because on Alpha a va_list is passed |
| 649 | by value, and lightning does not know about data types, so, cannot |
| 650 | understand it is pushing a va_list as argument. |
| 651 | |
| 652 | * lib/jit_names.c, lib/lightning.c: Minor changes for the new |
| 653 | jit_code_va_push. |
| 654 | |
| 655 | * check/cva_list.c: Update only test case using jit_va_push, to |
| 656 | pass a va_list to a C function. |
| 657 | |
| 658 | doc/body.texi: Better documentation of the varargs interface. |
| 659 | |
| 660 | * jit_alpha.c, jit_alpha-cpu.c: Update to properly push a |
| 661 | C va_list and correctly calculate varargs offset. |
| 662 | |
| 663 | * lib/jit_aarch64-sz.c, lib/jit_aarch64.c, lib/jit_alpha-sz.c, |
| 664 | lib/jit_arm-sz.c, lib/jit_arm.c, lib/jit_hppa-sz.c, lib/jit_hppa.c, |
| 665 | lib/jit_ia64-sz.c, lib/jit_ia64.c, lib/jit_mips-sz.c, lib/jit_mips.c, |
| 666 | lib/jit_ppc-sz.c, lib/jit_ppc.c, lib/jit_s390-sz.c, lib/jit_s390.c, |
| 667 | lib/jit_sparc-sz.c, lib/jit_sparc.c, lib/jit_x86-sz.c, lib/jit_x86.c: |
| 668 | Update for the new jit_va_push interface. |
| 669 | |
| 670 | 2018-02-22 Paulo Andrade <pcpa@gnu.org> |
| 671 | |
| 672 | * lib/jit_alpha-cpu.c: Always set t12 to the address of the |
| 673 | current function, to properly work on all systems. Previously |
| 674 | the shortcut did only work on Tru64. For Linux and glibc the |
| 675 | change is required. |
| 676 | |
| 677 | 2018-02-22 Paulo Andrade <pcpa@gnu.org> |
| 678 | |
| 679 | * lib/jit_aarch64.c, lib/jit_alpha.c, lib/jit_arm.c, |
| 680 | lib/jit_mips.c, lib/jit_ppc.c, lib/jit_sparc.c, lib/jit_x86.c: |
| 681 | Correct wrong logic in usage of jit_live in jit_retr. The |
| 682 | problem is that if a temporary is required during epilog, |
| 683 | the return register might be allocated, so, jit_live must always |
| 684 | be used. |
| 685 | |
| 686 | 2018-01-31 Paulo Andrade <pcpa@gnu.org> |
| 687 | |
| 688 | * lib/lightning.c: Avoid deep recursions when computing live |
| 689 | register ranges. |
| 690 | |
| 691 | 2018-01-31 Paulo Andrade <pcpa@gnu.org> |
| 692 | |
| 693 | * lib/jit_mips-cpu.c: Correct frame size and varargs |
| 694 | initialization for the n32 abi. |
| 695 | * lib/jit_mips.c, lib/jit_mips-fpu.c: Correct 32 bit abis |
| 696 | in big-endian. |
| 697 | |
| 698 | 2017-09-13 Paulo Andrade <pcpa@gnu.org> |
| 699 | |
| 700 | * configure.ac: Add check for binutils 2.29 prototype to the |
| 701 | disassembler function. |
| 702 | * lib/jit_disasm.c: Adapt for binutils 2.29 change. |
| 703 | |
| 704 | 2017-06-09 Paulo Andrade <pcpa@gnu.org> |
| 705 | |
| 706 | * include/lightning/jit_private.h, lib/lightning.c: Add a |
| 707 | second pass from start when computing register live ranges. |
| 708 | This should be used temporarily, and is required for certain |
| 709 | loop constructs, with several consecutive blocks not referencing |
| 710 | a live register. |
| 711 | |
| 712 | 2016-05-05 Paulo Andrade <pcpa@gnu.org> |
| 713 | |
| 714 | * lib/lightning.c: Correct wrong movr simplification, |
| 715 | remove no longer needed code to set return registers live |
| 716 | and update live register set when reaching a label boundary, |
| 717 | but do not descend if the block has been already visited. |
| 718 | The later need some tuning for complex code generation, where |
| 719 | it will still have issues. |
| 720 | |
| 721 | 2015-11-30 Paulo Andrade <pcpa@gnu.org> |
| 722 | |
| 723 | * doc/body.texi: Change documentation to no longer say |
| 724 | it is a variant of the Fibonacci sequence, and document |
| 725 | a proper implementation. |
| 726 | Thanks to Jon Arintok for pointing out that the Fibonacci |
| 727 | sequence generation was incorrect. It was documented, but |
| 728 | still confusing. |
| 729 | |
| 730 | * check/fib.tst, check/fib.ok, check/bp.tst, check/bp.ok, |
| 731 | doc/ifib.c, doc/rbif.c: Implement a proper Fibonacci |
| 732 | sequence implementation. |
| 733 | |
| 734 | 2015-07-03 Paulo Andrade <pcpa@gnu.org> |
| 735 | |
| 736 | * lib/jit_mips-cpu.c: Correct definition of htonr_ul. |
| 737 | Correct prolog/epilog/va* routines to work on o64 abi. |
| 738 | |
| 739 | * lib/jit_mips-fpu.c: Correct load of double literal |
| 740 | argument when not using a data buffer. |
| 741 | Remove alignment correction in vaarg_d if using the |
| 742 | new mips abi. |
| 743 | |
| 744 | * lib/jit_mips.c: Correct code to allow creating variadic |
| 745 | jit functions when using the new mips abi. |
| 746 | |
| 747 | * lib/jit_rewind.c: Minor adjust for rewind when using |
| 748 | the new mips abi, if there are varargs arguments in |
| 749 | registers. |
| 750 | |
| 751 | 2015-06-06 Paulo Andrade <pcpa@gnu.org> |
| 752 | |
| 753 | * lib/jit_ia64-cpu.c: Search backward for the last output |
| 754 | register used, otherwise would stop too early if a float |
| 755 | argument used the slot. |
| 756 | Correct offset of first va_list argument, and use proper |
| 757 | va_list abi. |
| 758 | |
| 759 | * lib/jit_ia64-fpu.c: Add new functions to move a gpr |
| 760 | to a fpr register, to counterpart the ones that move a |
| 761 | fpr to a gpr. These are required to properly implement |
| 762 | jit_getarg*_{f,d} on complex prototypes, or variadic |
| 763 | jit functions. |
| 764 | |
| 765 | * lib/jit_ia64-sz.c: Update for support to jit variadic |
| 766 | functions. |
| 767 | |
| 768 | * lib/jit_ia64.c: Implement proper abi for variadic |
| 769 | jit functions. |
| 770 | |
| 771 | 2015-06-04 Paulo Andrade <pcpa@gnu.org> |
| 772 | |
| 773 | * lib/jit_rewind.c: New file implementing generic functions |
| 774 | to "rewind", or rewrite IR code sequences. |
| 775 | |
| 776 | * include/lightning.h: Add several new codes, that previously |
| 777 | were a function call, that would synthesize the operation. |
| 778 | Now, there is a code for the operation, and a new flag to |
| 779 | know an operation is synthesized. |
| 780 | |
| 781 | * include/lightning/jit_private.h: Add several new macros to |
| 782 | help construct synthesized IR code sequences. |
| 783 | |
| 784 | * lib/Makefile.am: Update for lib/jit_rewind.c. |
| 785 | |
| 786 | * lib/jit_disasm.c: Update for a small rework on jit_node_t, |
| 787 | so that --enable-devel-disassembler does not need a change |
| 788 | in the layout of jit_node_t. |
| 789 | |
| 790 | * lib/jit_names.c: Update for the new codes. |
| 791 | |
| 792 | * lib/jit_print.c: Update to print more readable output, and |
| 793 | flag synthesized IR code sequences. |
| 794 | |
| 795 | * lib/jit_aarch64-sz.c, lib/jit_aarch64.c, |
| 796 | lib/jit_arm-sz.c, lib/jit_arm.c, lib/jit_x86-sz.c, |
| 797 | lib/jit_x86.c: Update for new synthesized IR code sequences. |
| 798 | |
| 799 | * lib/jit_ppc-cpu.c, lib/jit_ppc-fpu., lib/jit_ppc-sz.c, |
| 800 | lib/jit_ppc.c, lib/jit_mips-cpu.c, lib/jit_mips-fpu.c, |
| 801 | lib/jit_mips-sz.c, lib/jit_mips.c, lib/jit_s390-fpu.c, |
| 802 | lib/jit_s390-sz.c, lib/jit_s390.c: Update for new synthesized |
| 803 | IR code sequences and correct bugs in the initial varargs |
| 804 | implementation support. |
| 805 | |
| 806 | * lib/jit_alpha-sz.c, lib/jit_alpha.c, lib/jit_hppa-sz.c, |
| 807 | lib/jit_hppa.c, lib/jit_ia64-sz.c, lib/jit_ia64.c, |
| 808 | lib/jit_sparc-sz.c, lib/jit_sparc.c: Add generic, untested |
| 809 | support for the new synthesized IR code sequences. Known |
| 810 | most likely broken right now, and should be corrected once |
| 811 | access to these hosts is available. |
| 812 | |
| 813 | * lib/lightning.c: Update for new IR codes, and add support |
| 814 | for not yet existing instructions that change third argument. |
| 815 | |
| 816 | * size.c: Change to use different tables for LE and BE PowerPC. |
| 817 | Correct a wrong endif for x32. |
| 818 | |
| 819 | 2015-05-25 Paulo Andrade <pcpa@gnu.org> |
| 820 | |
| 821 | * check/cva_list.c: New file implementing a test to ensure |
| 822 | the value returned by jit_va_start is a valid C va_list. |
| 823 | |
| 824 | * check/va_list.ok: New simple helper file, as now the |
| 825 | va_list.tst test is enabled. |
| 826 | |
| 827 | * check/va_list.tst: Rewritten for an extensive variadic |
| 828 | jit functions test. |
| 829 | |
| 830 | * check/Makefile.am: Update for the new tests. |
| 831 | |
| 832 | * lib/jit_arm-cpu.c, lib/jit_arm-swf.c, lib/jit_arm-vfp.c, |
| 833 | lib/jit_arm.c: Correct broken software float in a previous |
| 834 | commit. Note that the hard float abi implementation is known |
| 835 | broken at this time, for special cases involving variadic |
| 836 | functions, and should be corrected next. |
| 837 | |
| 838 | lib/jit_x86-cpu.c, lib/jit_x86-sz.c, lib/jit_x86.c: Correct |
| 839 | the jit_va_list_t semantics to match C va_list. |
| 840 | |
| 841 | 2015-05-24 Paulo Andrade <pcpa@gnu.org> |
| 842 | |
| 843 | * lib/Makefile.am: Bump library major. This is a preparation |
| 844 | for a rework that was due for quite some time, but that is |
| 845 | now required to properly implement variadic jit functions. |
| 846 | The rework is mainly required to know at prolog parsing, if |
| 847 | a function is variadic or not. This will benefit a few |
| 848 | backends, and is mandatory for the hard float arm abi. |
| 849 | The rework was already planned for quite some time, to |
| 850 | be able to use a variable stack framesize, and for leaf |
| 851 | functions optimization where applicable. |
| 852 | The change will be source compatible, but will change |
| 853 | some internals, and jit_code_t values, as some new will |
| 854 | be added. |
| 855 | The only behavior change is that, jit_arg_register_p may |
| 856 | change return value on hard float arm abi, if called before |
| 857 | or after jit_ellipsis. Common sense anyway, would say to |
| 858 | make that call after jit_ellipsis, but documentation |
| 859 | should be updated for it. |
| 860 | |
| 861 | 2015-05-24 Paulo Andrade <pcpa@gnu.org> |
| 862 | |
| 863 | * lib/jit_aarch64-fpu.c, lib/jit_aarch64.c: Correct base |
| 864 | aarch64 varargs code. |
| 865 | |
| 866 | 2015-05-24 Paulo Andrade <pcpa@gnu.org> |
| 867 | |
| 868 | * check/lightning.c: Clearly run check if clang is the system |
| 869 | compiler. |
| 870 | |
| 871 | 2015-05-20 Paulo Andrade <pcpa@gnu.org> |
| 872 | |
| 873 | * lib/jit_sparc-cpu.c, lib/jit_sparc-fpu.c, lib/jit_sparc.c: |
| 874 | Add base support to jit vararg functions to the sparc backend. |
| 875 | |
| 876 | 2015-05-20 Paulo Andrade <pcpa@gnu.org> |
| 877 | |
| 878 | * lib/jit_alpha-cpu.c, lib/jit_alpha-fpu.c, lib/jit_alpha.c: |
| 879 | Add base support to jit vararg functions to the alpha backend. |
| 880 | |
| 881 | 2015-05-19 Paulo Andrade <pcpa@gnu.org> |
| 882 | |
| 883 | * lib/jit_hppa-cpu.c, lib/jit_hppa-fpu.c, lib/jit_hppa.c: |
| 884 | Add base support to jit vararg functions to the hppa backend. |
| 885 | |
| 886 | 2015-05-10 Paulo Andrade <pcpa@gnu.org> |
| 887 | |
| 888 | * lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c, lib/jit_ia64.c: |
| 889 | Add base support to jit vararg functions to the ia64 backend. |
| 890 | |
| 891 | 2015-05-10 Paulo Andrade <pcpa@gnu.org> |
| 892 | |
| 893 | * lib/jit_ia64-fpu.c, lib/jit_ia64.c: Correct movi_d_w |
| 894 | and movi_f_w implementation to work when not using a |
| 895 | data buffer. This causes the check varargs.tst to |
| 896 | work when passing "-d" to the lightning test tool. |
| 897 | |
| 898 | 2015-05-10 Paulo Andrade <pcpa@gnu.org> |
| 899 | |
| 900 | * lib/jit_ia64.c: Implement inline assembly cache flush, |
| 901 | required on multiprocessor systems. |
| 902 | |
| 903 | 2015-05-06 Paulo Andrade <pcpa@gnu.org> |
| 904 | |
| 905 | * lib/jit_mips-cpu.c, lib/jit_mips-fpu.c, lib/jit_mips.c: |
| 906 | Add base support to jit vararg functions to the mips backend. |
| 907 | Currently only supported on the o32 abi, until access to a |
| 908 | n32 system is arranged. |
| 909 | |
| 910 | 2015-05-05 Paulo Andrade <pcpa@gnu.org> |
| 911 | |
| 912 | * lib/jit_ppc-cpu.c, lib/jit_ppc-fpu.c, lib/jit_ppc.c: |
| 913 | Add base support to jit vararg functions to the PowerPC backend. |
| 914 | |
| 915 | 2015-05-02 Paulo Andrade <pcpa@gnu.org> |
| 916 | |
| 917 | * lib/jit_s390-cpu.c, lib/jit_s390-fpu.c, lib/jit_s390.c: |
| 918 | Add base support to jit vararg functions to the s390 backend. |
| 919 | |
| 920 | 2015-05-01 Paulo Andrade <pcpa@gnu.org> |
| 921 | |
| 922 | * lib/jit_arm-cpu.c, lib/jit_arm-swf.c, lib/jit_arm-vfp.c, |
| 923 | lib/jit_arm.c: Add base support to jit vararg |
| 924 | functions to the arm backend. |
| 925 | |
| 926 | 2015-04-30 Paulo Andrade <pcpa@gnu.org> |
| 927 | |
| 928 | * lib/jit_aarch64-cpu.c, lib/jit_aarch64-fpu.c, |
| 929 | lib/jit_aarch64.c: Add base support to jit vararg |
| 930 | functions to the aarch64 backend. |
| 931 | |
| 932 | 2015-04-27 Paulo Andrade <pcpa@gnu.org> |
| 933 | |
| 934 | * include/lightning.h, include/lightning/jit_private.h, |
| 935 | lib/jit_names.c, lib/lightning.c: Add initial support |
| 936 | for the new jit_va_start, jit_va_arg, jit_va_arg_d, and |
| 937 | jit_va_end interfaces. The jit_va_start call is supposed |
| 938 | to return a va_list compatible pointer, but not yet |
| 939 | decided if it will be "declared" stdarg compatible, |
| 940 | as for now only x86 support has been added (and should |
| 941 | be compatible), but issues may arise on other backends. |
| 942 | |
| 943 | * check/lightning.c: Add wrappers to call the new jit_va_* |
| 944 | interfaces. |
| 945 | |
| 946 | * lib/jit_x86-cpu.c, lib/jit_x86.c: Implement the new |
| 947 | jit_va_* for x86. |
| 948 | |
| 949 | * lib/jit_x86-sz.c: Add fields, but not yet fully updated, |
| 950 | as this is an intermediate commit. |
| 951 | |
| 952 | * lib/jit_aarch64-sz.c, lib/jit_aarch64.c, |
| 953 | lib/jit_alpha-sz.c, lib/jit_alpha.c, |
| 954 | lib/jit_arm-sz.c, lib/jit_arm.c, |
| 955 | lib/jit_hppa-sz.c, lib/jit_hppa.c, |
| 956 | lib/jit_ia64-sz.c, lib/jit_ia64.c, |
| 957 | lib/jit_mips-sz.c, lib/jit_mips.c, |
| 958 | lib/jit_ppc-sz.c, lib/jit_ppc.c, |
| 959 | lib/jit_s390-sz.c, lib/jit_s390.c, |
| 960 | lib/jit_sparc-sz.c, lib/jit_sparc.c: Prepare for the |
| 961 | new jit_va_* interfaces. Not yet implemented, and will |
| 962 | cause an assertion if used. |
| 963 | |
| 964 | * check/va_list.tst: Simple early test case, that works |
| 965 | on x86_64, x32, ix86, cygwin, and cygwin64. |
| 966 | |
| 967 | 2015-02-17 Paulo Andrade <pcpa@gnu.org> |
| 968 | |
| 969 | * include/lightning.h, include/lightning/jit_private.h, |
| 970 | lib/jit_aarch64-cpu.c, lib/jit_aarch64.c, |
| 971 | lib/jit_alpha-cpu.c, lib/jit_alpha.c, |
| 972 | lib/jit_arm-cpu.c, lib/jit_arm.c, |

| 977 | lib/jit_s390-cpu.c, lib/jit_s390.c, |
| 978 | lib/jit_sparc-cpu.c, lib/jit_sparc.c, |
| 979 | lib/jit_x86-cpu.c, lib/jit_x86.c: Implement the new |
| 980 | jit_allocar(offs, size) interface, that receives |
| 981 | two integer registers arguments, allocates space |
| 982 | dynamically in the stack, returns the offset in |
| 983 | the first argument, and uses the second argument |
| 984 | for the size in bytes of the memory to be allocated. |
| 985 | |
| 986 | * check/allocar.ok, check/allocar.tst: New files |
| 987 | implementing test cases for the new jit_allocar |
| 988 | interface. |
| 989 | |
| 990 | * check/Makefile.am, check/lightning.c: Update for |
| 991 | the new test case and interface. |
| 992 | |
| 993 | * doc/body.texi: Add documentation of the new |
| 994 | interface. |
| 995 | |
| 996 | 2015-02-17 Paulo Andrade <pcpa@gnu.org> |
| 997 | |
| 998 | * include/lightning/jit_x86.h, lib/jit_x86-cpu.c, |
| 999 | lib/jit_x86-x87.c: No longer make st(7) available. |
| 1000 | Need to keep one x87 slots empty to avoid exceptions. |
| 1001 | This has the side effect of no longer needing the |
| 1002 | hackish emms instruction before a function call. |
| 1003 | |
| 1004 | 2015-02-16 Paulo Andrade <pcpa@gnu.org> |
| 1005 | |
| 1006 | * lib/lightning.c: Remove the jit_regno_patch bitfield |
| 1007 | register fields before actual emit, as it is only really |
| 1008 | used before emit, otherwise, on special conditions it |
| 1009 | may consider live registers as dead during code emit. |
| 1010 | |
| 1011 | 2015-02-15 Paulo Andrade <pcpa@gnu.org> |
| 1012 | |
| 1013 | * lib/jit_x86-cpu.c, lib/jit_x86-sse.c, lib/jit_x86-x87.c: |
| 1014 | Correct encoding of ldxr* stxr* in the x32 abi. If the |
| 1015 | displacement register is negative, it would generate |
| 1016 | a 64 bit instruction with a 32 bit unsigned displacement. |
| 1017 | |
| 1018 | * check/ranger.tst, check/ranger.ok: New files, implementing |
| 1019 | a test case for negative loads and stores. This is range.tst |
| 1020 | converted to use registers instead of immediate offsets. |
| 1021 | |
| 1022 | check/Makefile.am: Update for the new test case. |
| 1023 | |
| 1024 | 2015-02-07 Paulo Andrade <pcpa@gnu.org> |
| 1025 | |
| 1026 | * lib/jit_size.c: Preventively use at least 144 bytes |
| 1027 | if JIT_INSTR_MAX is less than it. The logic is not |
| 1028 | guaranteed to be 100% precise, it is mostly heuristics |
| 1029 | to allocate a buffer with as close as possible size, |
| 1030 | but a wrong value may cause code generation to write |
| 1031 | past the end of the buffer. |
| 1032 | |
| 1033 | 2015-02-03 Paulo Andrade <pcpa@gnu.org> |
| 1034 | |
| 1035 | * lib/lightning.c: Correct the reason the bug in |
| 1036 | simplify_stxi was not triggered before, it was due to |
| 1037 | incorrectly resetting the value->code field, what was |
| 1038 | causing it to never properly optimize: |
| 1039 | stxi Im0 Rb0 Rt0 |
| 1040 | ldxi Rt1 Rb1 Im1 |
| 1041 | when Rb0 == Rb1, Rt0 == Rt1 and Im0 == Im1 |
| 1042 | There was another possible issue, that has been also |
| 1043 | addressed in this commit, that would be the case of |
| 1044 | Rbn == Rtn, where no redundancy removal is possible. |
| 1045 | |
| 1046 | 2015-02-03 Paulo Andrade <pcpa@gnu.org> |
| 1047 | |
| 1048 | * lib/lightning.c: Correct wrong check in simplify_stxi. |
| 1049 | The test was incorrectly comparing the target register |
| 1050 | and the displacement offset. This was a time bomb bug, |
| 1051 | that would trigger in code like: |
| 1052 | stxi Im0 Rb0 Rt0 |
| 1053 | stxi Im1 Rb1 Rt1 |
| 1054 | if Rb0 == Rb1 && Rt0 == Rt1 && Im0 == Rt1, that is, |
| 1055 | the wrong check was Im0 == Rt1, instead of the supposed |
| 1056 | Im0 == Imm1 (that was what the code mean't to do). It |
| 1057 | was removing the second stxi assuming it was redundantly |
| 1058 | generated; as that is not uncommon pattern on |
| 1059 | translators generating jit. |
| 1060 | |
| 1061 | 2015-02-02 Paulo Andrade <pcpa@gnu.org> |
| 1062 | |
| 1063 | * configure.ac, include/lightning/jit_private.h, |
| 1064 | lib/jit_aarch64.c, lib/jit_alpha.c, lib/jit_arm.c, |
| 1065 | lib/jit_disasm.c, lib/jit_hppa.c, lib/jit_ia64.c, |
| 1066 | lib/jit_mips.c, lib/jit_ppc.c, lib/jit_print.c, |
| 1067 | lib/jit_s390.c, lib/jit_sparc.c, lib/jit_x86.c: Add a new |
| 1068 | --enable-devel-disassembler option, that should be used |
| 1069 | during development, or lightning debug. This option |
| 1070 | intermixes previous jit_print and jit_disassemble |
| 1071 | output, making it easier to visualize what lightning |
| 1072 | call was used, and what code was generated. |
| 1073 | |
| 1074 | 2015-01-31 Paulo Andrade <pcpa@gnu.org> |
| 1075 | |
| 1076 | * lib/jit_arm-cpu.c, lib/jit_arm.c: Only limit to 24 bit |
| 1077 | displacement non conditional jump in the same jit_state_t. |
| 1078 | |
| 1079 | 2015-01-19 Paulo Andrade <pcpa@gnu.org> |
| 1080 | |
| 1081 | * doc/body.texi: Reorder documentation, making jit_frame |
| 1082 | and jit_tramp the lightning response to the need of |
| 1083 | trampolines, continuations and tail call optimizations. |
| 1084 | A pseudo code example of a factorial function was added. |
| 1085 | Also added a section for description of the available |
| 1086 | predicates. |
| 1087 | |
| 1088 | * doc/fact.c: New file, implementing a simple example of |
| 1089 | a translation of a trivial, recursive, tail call optimization |
| 1090 | into lightning calls. This is the conversion to functional C |
| 1091 | code of the example in doc/body.texi. |
| 1092 | |
| 1093 | * doc/Makefile.am: Update for the next test case. |
| 1094 | |
| 1095 | 2015-01-17 Paulo Andrade <pcpa@gnu.org> |
| 1096 | |
| 1097 | * include/lightning.h, lib/jit_aarch64.c, |
| 1098 | lib/jit_alpha.c, lib/jit_arm-vfp.c, lib/jit_arm.c, |
| 1099 | lib/jit_hppa.c, lib/jit_ia64.c, lib/jit_mips.c, |
| 1100 | lib/jit_ppc.c, lib/jit_s390.c, lib/jit_sparc.c, |
| 1101 | lib/jit_x86.c: Add the new jit_arg_register_p predicate. |
| 1102 | The predicate is expected to be used to know if an |
| 1103 | argument is in a register, what would need special |
| 1104 | handling if code that can overwrite non callee save |

| 1106 | |
| 1107 | * check/carg.c: New test case to check consistency and |

| 1126 | lib/jit_ppc.c, lib/jit_s390.c, |
| 1127 | lib/jit_sparc.c, lib/jit_x86.c: Remove jit_arg_reg_p and |
| 1128 | jit_arg_f_reg_p from a public header, and define it only |
| 1129 | on port specific files where an integer offset is used |
| 1130 | to qualify an argument identifier. Exported code expects |
| 1131 | an opaque pointer (but of jit_node_t* type) to "qualify" |
| 1132 | an argument identifier. |
| 1133 | This patch, and the code review/simplification done during |
| 1134 | it also corrected some bugs: |
| 1135 | o Inconsistent jit_arg_d value of double argument after 3 |
| 1136 | integer arguments in arm for jit_functions; tested, C |
| 1137 | functions were being properly called. |
| 1138 | o Inconsistent use of getarg_{f,d} and putarg*_{f,d} on |
| 1139 | s390 (32-bit) that happened to not have a proper test |
| 1140 | case, as it would only happen for jit functions, and |
| 1141 | tested, called C functions had proper arguments. |
| 1142 | o Corrected a "last minute" correction that did not go |
| 1143 | to the committed version, and would not compile on hppa, |
| 1144 | due to bad _jit_putargi_d prototype definition. |
| 1145 | |
| 1146 | 2015-01-17 Paulo Andrade <pcpa@gnu.org> |
| 1147 | |
| 1148 | * doc/body.texi: Correct wrong/outdated information for |
| 1149 | hton*, pusharg* and ret*, and add missing documentation |
| 1150 | for rsb*, qmul*, qdvi* and putarg*. |
| 1151 | |
| 1152 | 2015-01-15 Paulo Andrade <pcpa@gnu.org> |

| 1162 | lib/jit_s390.c, lib/jit_sparc.c, lib/jit_x86.c: |
| 1163 | Implement jit_putarg*. It works as a mix of jit_getarg* |
| 1164 | and jit_pusharg*, in the way that the first argument is |
| 1165 | a register or immediate, and the second is a pointer |
| 1166 | returned by jit_arg*. The use of the interface is to change |
| 1167 | values of arguments to the current jit function. |
| 1168 | |
| 1169 | * check/put.ok, check/put.tst: New test cases exercising |
| 1170 | the new jit_putarg* interface. |

| 1191 | lib/jit_s390x.c, lib/jit_size.c, lib/lightning.c: |
| 1192 | Add support for generating jit for s390 32 bit. This change |
| 1193 | also removed %f15 from the list of temporaries fpr registers; |
| 1194 | it was not being used, but if were, it would corrupt the |
| 1195 | stack frame because the spill address would overwrite grp |

| 1208 | |
| 1209 | 2014-12-26 Paulo Andrade <pcpa@gnu.org> |

| 1249 | |
| 1250 | * lib/jit_arm.c: Call __clear_cache for every page. |
| 1251 | This should only be required for older boards or |
| 1252 | toolchain setup, but has been reported to be required |
| 1253 | for lightning at some point. |
| 1254 | |
| 1255 | 2014-12-21 Paulo Andrade <pcpa@gnu.org> |
| 1256 | |
| 1257 | * lib/jit_arm.c: Correct check to guard overflow of index |
| 1258 | of constants from program counter. |
| 1259 | |
| 1260 | 2014-11-24 Paulo Andrade <pcpa@gnu.org> |
| 1261 | |
| 1262 | * lib/lightning.c: Remove an optimization to calee save |

| 1265 | |
| 1266 | 2014-11-20 Paulo Andrade <pcpa@gnu.org> |
| 1267 | |
| 1268 | * include/lightning/jit_ppc.h, lib/jit_ppc-cpu.c, |

| 1270 | |
| 1271 | 2014-11-20 Paulo Andrade <pcpa@gnu.org> |
| 1272 | |
| 1273 | * lib/jit_disasm.c: Change thumb or arm disassemble based on |
| 1274 | jit code before disassembly. |
| 1275 | |
| 1276 | * lib/jit_arm-cpu.c: Correct reversed arguments to LDRD and |
| 1277 | STRD instructions, and correct checking for support of those. |
| 1278 | |
| 1279 | * lib/jit_arm-swf.c: Correct wrong use of LDRD and STRD and |
| 1280 | only use those if the register is even. |
| 1281 | |
| 1282 | * check/check.arm.swf.sh, check/check.arm4.swf.sh: New files |
| 1283 | to test LDRD and STRD, as well as the alternate code path |
| 1284 | when those are not available, in the .arm4. test case. |
| 1285 | |
| 1286 | * check/Makefile.am: Update for the new test cases. |

| 1293 | lib/jit_s390x.c, lib/jit_sparc.c, lib/jit_x86.c: |
| 1294 | Implement a private jit_flush call, that flushes |
| 1295 | the cache, if applicable, aligning down to the |
| 1296 | previous and up to the next page boundary. |
| 1297 | |
| 1298 | 2014-11-08 Paulo Andrade <pcpa@gnu.org> |
| 1299 | |
| 1300 | * check/ctramp.c: New file. It just repeats the test |
| 1301 | of tramp.tst, but using two jit_state_t, what should |
| 1302 | test possible issues with two contexts, and also validate |
| 1303 | jit_tramp works on backends with function descriptions. |
| 1304 | |
| 1305 | * check/Makefile.am: Update for new test case. |
| 1306 | |
| 1307 | 2014-11-03 Paulo Andrade <pcpa@gnu.org> |
| 1308 | |
| 1309 | * include/lightning/jit_mips.h: Do not make the t9 register |
| 1310 | JIT_R11 (or JIT_R7 for n32 or n64 abi) available. Previously |
| 1311 | it cause problems if one expects it to not be changed in a |
| 1312 | function call. For example, calling a jit function, where it |
| 1313 | really does not need to be changed. |
| 1314 | |
| 1315 | 2014-10-26 Paulo Andrade <pcpa@gnu.org> |
| 1316 | |

| 1319 | lib/jit_s390x.c, lib/jit_sparc.c, lib/jit_x86.c: Add an |
| 1320 | assertion to all code generation "drivers" to ensure |
| 1321 | _jitc->regarg is empty or in an expected state, after |
| 1322 | translation of a lightning instruction to native code. |
| 1323 | This change was a brute force test to find out other cases |
| 1324 | of a temporary not being release (like was happening with |
| 1325 | _bmsi and _bmci on x86), but no other case was found, |
| 1326 | after running make check, with assertions enabled, on all |
| 1327 | backends. |
| 1328 | |
| 1329 | 2014-10-26 Paulo Andrade <pcpa@gnu.org> |
| 1330 | |
| 1331 | * lib/jit_x86-cpu.c: Correct a register allocation leak in |
| 1332 | _bmsi and _bmci. |
| 1333 | |
| 1334 | 2014-10-25 Paulo Andrade <pcpa@gnu.org> |
| 1335 | |
| 1336 | * lib/jit_disasm.c: Do not cause an fatal error if init_jit |
| 1337 | fails in the jit_init_debug call. |
| 1338 | |
| 1339 | 2014-10-24 Paulo Andrade <pcpa@gnu.org> |
| 1340 | |
| 1341 | * lib/jit_ia64.c, lib/jit_ppc.c: Correct handling of function |
| 1342 | descriptor when first prolog is a jit_tramp prolog. The |
| 1343 | test case was using the same jit_context_t, so was not |
| 1344 | triggering this condition. |
| 1345 | |
| 1346 | * lib/jit_ppc-cpu.c: Properly handle jump displacements that |
| 1347 | do not fit on 24 powerpc. This required changing from previous |
| 1348 | "mtlr reg, blr" to "mtctr reg, bctr" to properly handle |
| 1349 | the logic to "hide" function descriptors, but that would |
| 1350 | also be required as the proper jit_jmpr when/if implementing |
| 1351 | optimizations to leaf functions (was working with blr because |
| 1352 | it is saved/reloaded in prolog/epilog). |
| 1353 | |
| 1354 | 2014-10-21 Paulo Andrade <pcpa@gnu.org> |
| 1355 | |
| 1356 | * include/lightning.h, lib/lightning.c: Add three predicates |
| 1357 | to query information about labels. jit_forward_p(label) |
| 1358 | will return non zero if the label is "forward", that is |
| 1359 | need a call to jit_link(label), jit_indirect_p(label) |
| 1360 | that returns non zero if the label was created with the |
| 1361 | jit_indirect() call, and jit_target_p(label) that will |
| 1362 | return non zero if there is at least one jump patched |
| 1363 | to land at that label. |
| 1364 | |
| 1365 | 2014-10-18 Paulo Andrade <pcpa@gnu.org> |
| 1366 | |
| 1367 | * check/range.ok, check/range.tst: New test case designed |
| 1368 | to catch incorrect code generation, usually due to incorrect |
| 1369 | test of immediate size. The test checks a large amount of |
| 1370 | encodings in "power of two" boundaries. This test exorcises |
| 1371 | a significant amount of code paths that was previously not |
| 1372 | tested. |
| 1373 | |
| 1374 | * check/Makefile.am: Add range test to make check target. |
| 1375 | |
| 1376 | * lib/jit_aarch64-cpu.c: Correct wrong address calculation |
| 1377 | for stxi_c, stxi_s, stxi_i and stxi_l when the offset is |
| 1378 | too large. |
| 1379 | |
| 1380 | * lib/jit_mips-fpu.c: Correct wrong size test to check if |
| 1381 | an immediate can be encoded in a float or double store. |
| 1382 | |
| 1383 | * lib/jit_s390x-cpu.c: Correct inverted encoding to stxi_s |
| 1384 | when the offset cannot be encoded, and fallbacks to an |
| 1385 | alternate encoding in 2 instructions. |
| 1386 | |
| 1387 | 2014-10-17 Paulo Andrade <pcpa@gnu.org> |
| 1388 | |
| 1389 | * check/alu_rsb.ok, check/alu_rsb.tst: New files implementing |
| 1390 | tests for jit_rsb*. |
| 1391 | |
| 1392 | * check/Makefile.am, check/lightning.c, include/lightning.h, |

| 1407 | lib/jit_x86.c, lib/lightning.c: Implement jit_rsb*. This |
| 1408 | was a missing lightning 1.x interface, that on most |
| 1409 | backends is synthesized, but on a few backends (hppa and ia64), |
| 1410 | it can generate better code as on those there is, or the |
| 1411 | only instruction with an immediate is in "rsb" format |
| 1412 | (left operand). |
| 1413 | |
| 1414 | 2014-10-17 Paulo Andrade <pcpa@gnu.org> |
| 1415 | |
| 1416 | * lib/jit_names.c: New file with single definition of string |
| 1417 | representation of lightning IR codes. |
| 1418 | |
| 1419 | * size.c: Modified to append the code name in a C comment |
| 1420 | after the maximum instruction size. |
| 1421 | |
| 1422 | * lib/jit_print.c: Minor change to not duplicate jit_names.c |
| 1423 | contents. |
| 1424 | |
| 1425 | * lib/jit_aarch64-sz.c, lib/jit_alpha-sz.c, lib/jit_arm-sz.c, |

| 1428 | lib/jit_x86-sz.c: Rewritten to add string representation of |
| 1429 | IR codes in a C comment. |
| 1430 | |
| 1431 | 2014-10-14 Paulo Andrade <pcpa@gnu.org> |
| 1432 | |

| 1434 | lib/jit_hppa-cpu.c, lib/jit_mips-cpu.c, lib/jit_ppc-cpu.c, |
| 1435 | lib/jit_sparc-cpu.c: Implement or correct the internal |
| 1436 | nop(count) call that receives an argument that tells the |
| 1437 | modulo bytes to align the code for the next instruction. |
| 1438 | |
| 1439 | * include/lightning.h, lib/lightning.c, lib/jit_aarch64.c, |

| 1441 | lib/jit_mips.c, lib/jit_ppc.c, lib/jit_s390x.c, lib/jit_sparc.c, |
| 1442 | lib/jit_x86.c: Implement the new jit_align() call that receive |
| 1443 | an argument, that tells the modulo, in bytes, to align the |
| 1444 | next instruction. In most backends the only value that makes |
| 1445 | a difference is a value that matches sizeof(void*), as all |
| 1446 | other values usually are already automatically aligned in |
| 1447 | labels, but not guaranteed to be aligned at word size bytes. |
| 1448 | |
| 1449 | * check/align.ok, check/align.tst: New files, implementing |
| 1450 | a simple test for the new jit_align() interface. |
| 1451 | |
| 1452 | * check/Makefile.am, check/lightning.c, lib/jit_aarch64-sz.c, |
| 1453 | lib/jit_alpha-sz.c, lib/jit_arm-sz.c, lib/jit_hppa-sz.c, |

| 1455 | lib/jit_print.c, lib/jit_s390x-sz.c, lib/jit_sparc-sz.c, |
| 1456 | lib/jit_x86-sz.c: Update for the new jit_code_align code and |
| 1457 | the jit_align() interface. |
| 1458 | |
| 1459 | 2014-10-13 Paulo Andrade <pcpa@gnu.org> |
| 1460 | |
| 1461 | * include/lightning.h, lib/jit_size.c, size.c: Use a |
| 1462 | symbolic value for the last IR code. |
| 1463 | |
| 1464 | 2014-10-12 Paulo Andrade <pcpa@gnu.org> |
| 1465 | |
| 1466 | * include/lightning.h, include/lightning/jit_private.h, |
| 1467 | lib/jit_aarch64-cpu.c, lib/jit_alpha-cpu.c, lib/jit_arm-cpu.c, |
| 1468 | lib/jit_hppa-cpu.c, lib/jit_ia64-cpu.c, lib/jit_mips-cpu.c, |
| 1469 | lib/jit_ppc-cpu.c, lib/jit_s390x-cpu.c, lib/jit_sparc-cpu.c, |
| 1470 | lib/jit_x86-cpu.c, lib/lightning.c: Implement the new |
| 1471 | jit_frame and jit_tramp interfaces, that allow writing |
| 1472 | trampoline like calls, where a single dispatcher jit buffer |
| 1473 | is written, and later other jit buffers are created, with |
| 1474 | the same stack frame layout as the dispatcher. This is the |
| 1475 | logic that GNU Smalltalk used in lightning 1.x, and is required |
| 1476 | to make a sane port for lighting 2.x. |
| 1477 | |
| 1478 | * jit_ia64-cpu.c: Implement support for jit_frame and jit_tramp, |
| 1479 | and also correct wrong encoding for B4 instructions, that |
| 1480 | implement jmpr, as well as correct reverse logic in _jmpr, |
| 1481 | that was moving the branch register to the jump register, |
| 1482 | and not vice-versa. |
| 1483 | Also, if a stack frame is to be assumed, always assume it may |
| 1484 | call a function with up to 8 arguments, regardless of the |
| 1485 | hint frame argument. |
| 1486 | |
| 1487 | * lib/jit_arm.c: Add a new must_align_p() interface to ensure |
| 1488 | function prologs are always aligned. This condition was |
| 1489 | previously always true, somewhat by accident, but with |
| 1490 | jit_tramp it is not guaranteed. |
| 1491 | |
| 1492 | * jit_ia64-cpu.c: lib/jit_ppc.c: Add minor special handling |
| 1493 | required to implement jit_tramp, where a function descriptor |
| 1494 | should not be added before a prolog, as jit_tramp means omit |
| 1495 | prolog. |
| 1496 | |
| 1497 | * check/lightning.c: Update test driver for the new interfaces. |
| 1498 | |
| 1499 | * check/Makefile.am, check/tramp.tst, check/tramp.ok: Add |
| 1500 | a simple test and example of the jit_frame and jit_tramp |
| 1501 | usage implementing a simple Fibonacci function using a |
| 1502 | simulation of an interpreter stack and how it would handle |
| 1503 | state in language specific variables. |
| 1504 | |
| 1505 | * doc/body.texi: Add documentation for jit_frame and |
| 1506 | jit_tramp. |
| 1507 | |
| 1508 | 2014-09-29 Paulo Andrade <pcpa@gnu.org> |
| 1509 | |
| 1510 | * lib/jit_aarch64.c, lib/jit_alpha.c, lib/jit_arm.c, |
| 1511 | lib/jit_hppa.c, lib/jit_ia64.c, lib/jit_mips.c, |
| 1512 | lib/jit_ppc.c, lib/jit_s390x.c, lib/jit_sparc.c, |
| 1513 | lib/jit_x86.c, lib/lightning.c: Allow jit_jmpi on a |
| 1514 | target that is not a node. This may lead to hard to |
| 1515 | debug code generation, but is a required feature for |
| 1516 | certain generators, like the ones that used lightning |
| 1517 | 1.2x. Note that previously, but not really well |
| 1518 | documented, it was instructed to use: |
| 1519 | jit_movi(rn, addr); jit_jmpr(rn); |
| 1520 | but now, plain: |
| 1521 | jit_patch_abs(jit_jmpi(), addr); |
| 1522 | should also work. |
| 1523 | |
| 1524 | 2014-09-24 Paulo Andrade <pcpa@gnu.org> |
| 1525 | |
| 1526 | * lib/jit_x86-sz.c: Generate information about instruction |
| 1527 | lengths for more precise calculation of buffer size on |
| 1528 | Windows x64. This change is specially important because |
| 1529 | the maximum instruction length is larger than other |
| 1530 | systems, what could cause an out of bounds write on |
| 1531 | special conditions without this update. |
| 1532 | |
| 1533 | 2014-09-24 Paulo Andrade <pcpa@gnu.org> |
| 1534 | |
| 1535 | * check/lightning.c: Add workaround to conflicting global |
| 1536 | optind variable in cygwin binutils that have an internal |
| 1537 | getopt* implementation. |
| 1538 | |
| 1539 | * lib/jit_x86-cpu.c: Add a simple define ffsl ffs if building |
| 1540 | for 32 bit and there is no ffsl function. |
| 1541 | |
| 1542 | 2014-09-24 Paulo Andrade <pcpa@gnu.org> |
| 1543 | |
| 1544 | * check/lightning.c: Add a hopefully temporary kludge to not use |
| 1545 | sprintf and sscanf returned by dlsym. This is required to pass |
| 1546 | the varargs test. |
| 1547 | |
| 1548 | * include/lightning/jit_private.h: Use symbolic name for first |
| 1549 | integer register argument, as this is different in sysv and |
| 1550 | win64 abi. |
| 1551 | |
| 1552 | * include/lightning/jit_x86.h: Add conditionals and definitions |
| 1553 | for Windows x64 (under __CYGWIN__ preprocessor conditional). |
| 1554 | |
| 1555 | * lib/jit_x86-cpu.c: Correct one instruction encoding bug, that |
| 1556 | was working by accident. Only use rax to rdx for some byte |
| 1557 | operations to work on compatibility mode (that is, to generate |
| 1558 | the proper encoding, instead of actually generating encoding |
| 1559 | for high byte registers, e.g. %bh). |
| 1560 | Add proper prolog and epilog for windows x64. |
| 1561 | |
| 1562 | * lib/jit_x86-sse.c: Correct a swapped rex prefix for float |
| 1563 | operations. |
| 1564 | |
| 1565 | * lib/jit_x86.c: Adjust to support Windows x64 abi. |
| 1566 | |
| 1567 | * check/check.x87.nodata.sh: New file, previously used but that |
| 1568 | was missing git. |
| 1569 | |
| 1570 | 2014-09-07 Paulo Andrade <pcpa@gnu.org> |
| 1571 | |
| 1572 | * lib/lightning.c: Mark all registers advertised as live, as |
| 1573 | per jit_callee_save_p as live whenever reaching a jump that |
| 1574 | cannot be tracked. This is a rethink of the previous commit, |
| 1575 | and is a better approach, otherwise there would not be much |
| 1576 | sense on relying on jit_callee_save_p if it could not be |
| 1577 | trusted. |
| 1578 | |
| 1579 | * check/jmpr.tst, check/jmpr.ok: New files implementing a very |
| 1580 | simple test case, that would actually cause an assertion on |
| 1581 | code before the change to only mark as live when reaching a |
| 1582 | jump that could not tracked, the actually advertised as callee |
| 1583 | save registers. |
| 1584 | |
| 1585 | check/Makefile.am: Update for new jmpr test case. |
| 1586 | |
| 1587 | 2014-09-01 Paulo Andrade <pcpa@gnu.org> |
| 1588 | |
| 1589 | * lib/lightning.c: Do not mark all registers in unknown state |
| 1590 | as live on jit_jmpr, or jit_jmpi to an absolute address. Instead, |
| 1591 | treat it as a function call, and only consider JIT_Vn registers |
| 1592 | as possibly live. |
| 1593 | |
| 1594 | 2014-08-29 Paulo Andrade <pcpa@gnu.org> |
| 1595 | |
| 1596 | * doc/body.texi: Add a proper info menu entry for |
| 1597 | GNU lightning. |
| 1598 | |
| 1599 | * doc/version.texi: Regenerate. |
| 1600 | |
| 1601 | 2014-08-16 Paulo Andrade <pcpa@gnu.org> |
| 1602 | |
| 1603 | * lib/jit_aarch64-cpu.c, lib/jit_aarch64-fpu.c, |

| 1605 | lib/jit_hppa-cpu.c, lib/jit_hppa-fpu.c, |

| 1611 | lib/jit_x86-cpu.c, lib/jit_x86-sse.c, |
| 1612 | lib/jit_x86-x87.c: Review generation of all branch |
| 1613 | instructions and always adds the jit_class_nospill |
| 1614 | bitfield for temporary registers that cannot be spilled |
| 1615 | because the reload would be after a conditional jump; the |
| 1616 | patch only adds an extra assertion. These conditions do |
| 1617 | not happen on documented lightning usage, but can happen |
| 1618 | if one uses the not exported jit_get_reg and jit_unget_reg |
| 1619 | calls and cause enough register starvation. |
| 1620 | |
| 1621 | 2014-08-16 Paulo Andrade <pcpa@gnu.org> |
| 1622 | |
| 1623 | * lib/jit_alpha.c: Correct wrong bitmask of most argument |
| 1624 | float register arguments, that were being set as callee |
| 1625 | save instead of argument registers class. |
| 1626 | |
| 1627 | 2014-08-16 Paulo Andrade <pcpa@gnu.org> |
| 1628 | |
| 1629 | * lib/jit_arm-sz.c: Regenerate table of known maximum |
| 1630 | instruction sizes for the software float fallback, |
| 1631 | that implements "virtual" float registers in the stack |
| 1632 | and operations as calls to libgcc. |
| 1633 | |
| 1634 | * size.c: Correct typo in the generated jit_arm-sz.c file. |
| 1635 | |
| 1636 | 2014-08-10 Paulo Andrade <pcpa@gnu.org> |
| 1637 | |
| 1638 | * include/lightning/jit_alpha.h, lib/jit_alpha-cpu.c, |
| 1639 | lib/jit_alpha-fpu.c, lib/jit_alpha-sz.c, lib/jit_alpha.c: |
| 1640 | New files implementing a lightning Alpha port. Thanks |
| 1641 | to Trent Nelson and snakebit.net staff for providing access |
| 1642 | to an Alpha system. |
| 1643 | |
| 1644 | * check/float.tst, check/lightning.c, configure.ac, |
| 1645 | include/lightning.h, include/lightning/Makefile.am, |
| 1646 | include/lightning/jit_private.h, lib/Makefile.am, |
| 1647 | lib/jit_disasm.c, lib/jit_size.c, lib/lightning.c: |
| 1648 | Minor changes to adapt for the new Alpha port. |
| 1649 | |
| 1650 | 2014-08-10 Paulo Andrade <pcpa@gnu.org> |
| 1651 | |
| 1652 | * lib/lightning.c: Always mark JIT_RET and JIT_FRET as |
| 1653 | live in a function epilog. This is required because |
| 1654 | on some ports a complex sequence, allocating one or more |
| 1655 | registers, may be required to jump from a ret* to the |
| 1656 | epilog, and the lightning api does not have annotations |
| 1657 | to know if a function returns a value, or the type of |
| 1658 | the return value. |
| 1659 | |
| 1660 | 2014-08-10 Paulo Andrade <pcpa@gnu.org> |
| 1661 | |
| 1662 | * lib/lightning.c: Change the correct live bitmask of |
| 1663 | return registers after a function call in jit_update. |
| 1664 | |
| 1665 | 2014-08-10 Paulo Andrade <pcpa@gnu.org> |
| 1666 | |
| 1667 | * lib/lightning.c: Change assertions to have an int |
| 1668 | result and correct a bad bit mask assertion. |
| 1669 | |
| 1670 | 2014-08-10 Paulo Andrade <pcpa@gnu.org> |
| 1671 | |
| 1672 | * lib/jit_aarch64.c: Correct bad setup for assertion |
| 1673 | of consistency before a patch. |
| 1674 | |
| 1675 | 2014-08-10 Paulo Andrade <pcpa@gnu.org> |
| 1676 | |
| 1677 | * lib/jit_mips-cpu.c: Correct typo in the jit_bmsr |
| 1678 | implementation that was using the wrong test result |
| 1679 | register. |
| 1680 | |
| 1681 | 2014-07-28 Paulo Andrade <pcpa@gnu.org> |
| 1682 | |
| 1683 | * lib/jit_memory.c: Do not call free on NULL pointers. |
| 1684 | |
| 1685 | * include/lightning/jit_private.h, lib/jit_note.c, |
| 1686 | lib/lightning.c: Add a wrapper to memcpy and memmove |
| 1687 | to not actually call those functions with a zero size |
| 1688 | argument, and likely also a null src or dst. |
| 1689 | |
| 1690 | 2014-07-27 Paulo Andrade <pcpa@gnu.org> |
| 1691 | |
| 1692 | * include/lightning/jit_private.h, lib/jit_disasm.c, |
| 1693 | lib/lightning.c: Remove the global jit_progname variable. |
| 1694 | It was being only used in jit_init_debug, that is called |
| 1695 | from init_jit, so, just pass an argument. |
| 1696 | |
| 1697 | 2014-07-27 Paulo Andrade <pcpa@gnu.org> |
| 1698 | |
| 1699 | * doc/body.texi: Add note that jit_set_memory_functions |
| 1700 | should be called before init_jit, because init_jit |
| 1701 | itself may call the memory wrappers. |
| 1702 | |
| 1703 | 2014-04-22 Paulo Andrade <pcpa@gnu.org> |
| 1704 | |
| 1705 | * lib/jit_arm.c: Do not get confused with default settings |
| 1706 | if /proc is not mounted on Linux specific code path. |
| 1707 | |
| 1708 | 2014-04-09 Paulo Andrade <pcpa@gnu.org> |
| 1709 | |
| 1710 | * include/lightning/jit_aarch64.h, include/lightning/jit_arm.h, |
| 1711 | include/lightning/jit_hppa.h, include/lightning/jit_ia64.h, |
| 1712 | include/lightning/jit_mips.h, include/lightning/jit_ppc.h, |
| 1713 | include/lightning/jit_private.h, include/lightning/jit_s390x.h, |
| 1714 | include/lightning/jit_sparc.h, include/lightning/jit_x86.h: |
| 1715 | Do not add jit_regset_t, JIT_RA0, and JIT_FA0 to the installed |
| 1716 | header file. These types and definitions are supposed to be |
| 1717 | only used internally. |
| 1718 | |
| 1719 | 2014-04-05 Paulo Andrade <pcpa@gnu.org> |
| 1720 | |
| 1721 | * lib/jit_arm-cpu.c: Only adjust stack pointer in prolog if |
| 1722 | need stack space, that is, do not emit a nop instruction |
| 1723 | subtracting zero from the stack pointer. |
| 1724 | |
| 1725 | 2014-04-04 Paulo Andrade <pcpa@gnu.org> |
| 1726 | |
| 1727 | * lib/jit_disasm.c: Correct a crash in the doc/printf example |
| 1728 | on arm due to releasing the data_info information in |
| 1729 | jit_clear_state. This is a special case for arm only, and |
| 1730 | actually, only armv5 or older uses the data_info buffer, |
| 1731 | or when forcing arm instruction set mode besides thumb |
| 1732 | available. |
| 1733 | |
| 1734 | 2014-12-03 Paulo Andrade <pcpa@gnu.org> |
| 1735 | |
| 1736 | * doc/body.texi: Write detailed description and examples for |
| 1737 | jit_get_memory_functions, jit_set_memory_functions, |
| 1738 | jit_get_code, jit_set_code, jit_get_data and jit_set_data. |
| 1739 | |
| 1740 | 2014-12-03 Paulo Andrade <pcpa@gnu.org> |
| 1741 | |
| 1742 | * include/lightning.h, include/lightning/jit_private.h, |
| 1743 | lib/lightning.c: Implement the new jit_set_data() interface, |
| 1744 | and the new jit_get_data() helper. Like jit_set_code(), |
| 1745 | jit_realize() should be called before jit_set_data(). |
| 1746 | The most common usage should be jit_set_data(JIT_DISABLE_DATA |
| 1747 | | JIT_DISABLE_NOTE), to force synthesize any float/double |
| 1748 | constant in the stack and not generate any debug information. |
| 1749 | |
| 1750 | * lib/jit_note.c: Minor change to debug note generation as |
| 1751 | now it uses an alternate temporary data buffer during constants |
| 1752 | and debug generation to accommodate the possibility of the user |
| 1753 | setting an alternate data buffer. |
| 1754 | |
| 1755 | * lib/jit_hppa-fpu.c, lib/jit_s390x.c, lib/jit_s390x-cpu.c, |
| 1756 | lib/jit_s390x-fpu.c, lib/jit_sparc.c, lib/jit_sparc-fpu.c, |
| 1757 | lib/jit_x86-sse.c, lib/jit_x86-x87.c: Implement jit_set_data. |
| 1758 | |
| 1759 | * lib/jit_hppa-sz.c, lib/jit_sparc-sz.c, lib/jit_x86-sz.c, |
| 1760 | lib/jit_s390x-sz.c: Update for several instructions that now |
| 1761 | have a different maximum length due to jit_set_data. |
| 1762 | |
| 1763 | * lib/jit_mips-fpu.c: Implement jit_set_data, but missing |
| 1764 | validation on n32 and n64 abis (and/or big endian). |
| 1765 | |
| 1766 | * lib/jit_mips-sz.c: Update for changes in o32. |
| 1767 | |
| 1768 | * lib/jit_ppc-fpu.c: Implement jit_set_data, but missing |
| 1769 | validation on Darwin PPC. |
| 1770 | |
| 1771 | * lib/jit_ppc-sz.c: Update for changes in powerpc 32 and |
| 1772 | 64 bit. |
| 1773 | |
| 1774 | * lib/jit_ia64-fpu.c: Implement untested jit_set_data. |
| 1775 | |
| 1776 | * TODO: Add note to list ports that were not tested for the |
| 1777 | new jit_set_data() feature, due to no longer having access |
| 1778 | to them. |
| 1779 | |
| 1780 | * check/nodata.c: New file implementing a simple test exercising |
| 1781 | several different conditions created by jit_set_data(). |
| 1782 | |
| 1783 | * check/check.nodata.sh: New file implementing a wrapper |
| 1784 | over the existing *.tst files, that runs all tests without |
| 1785 | using a data buffer for constants; only meaningful (and |
| 1786 | enabled) on architectures that used to store float/double |
| 1787 | constants on a read only data buffer. |
| 1788 | |
| 1789 | * configure.ac, check/Makefile.am: Update for the new test |
| 1790 | cases. |
| 1791 | |
| 1792 | * check/lightning.c: Implement the new "-d" option that |
| 1793 | sets an internal flag to call jit_set_data() disable |
| 1794 | constants and debug, that is, using only a pure code |
| 1795 | buffer. |
| 1796 | |
| 1797 | 2014-11-03 Paulo Andrade <pcpa@gnu.org> |
| 1798 | |
| 1799 | * include/lightning.h, include/lightning/jit_private.h, |
| 1800 | lib/lightning.c: Implement the new jit_set_code() interface, |
| 1801 | that allows instructing lightning to use an alternate code |
| 1802 | buffer. The new jit_realize() function should be called |
| 1803 | before jit_set_code(), and usually call jit_get_code() |
| 1804 | to query the amount of bytes expected to be required for |
| 1805 | the code. |
| 1806 | |
| 1807 | * lib/jit_size.c: Minor update to have less chances of |
| 1808 | miscalculating the code buffer by starting the counter |
| 1809 | with the size of the longest instruction instead of zero, |
| 1810 | as code emit fails if at any moment less than the longest |
| 1811 | instruction bytes are available. |
| 1812 | |
| 1813 | * check/setcode.c: New file implementing some basic tests |
| 1814 | of the new jit_set_code() interface. |
| 1815 | |
| 1816 | * check/Makefile.am: Update for newer test case. |
| 1817 | |
| 1818 | 2014-06-03 Paulo Andrade <pcpa@gnu.org> |
| 1819 | |
| 1820 | * include/lightning.h, lib/lightning.c: Add the new |
| 1821 | jit_indirect() call, that returns a special label node, |
| 1822 | and tells lightning that the label may be the target of |
| 1823 | an indirect jump. |
| 1824 | |
| 1825 | * doc/body.texi: Document the new jit_indirect() call, and |
| 1826 | add examples of different ways to create labels and branches. |
| 1827 | |
| 1828 | 2014-23-02 Paulo Andrade <pcpa@gnu.org> |
| 1829 | |
| 1830 | * lib/jit_x86.c: Rewrite previous patch to inline save/restore |
| 1831 | because clobbering %ebx in x86 is treated as an error |
| 1832 | (jit_x86.c:239:5: error: PIC register clobbered by 'ebx' in 'asm'). |
| 1833 | |
| 1834 | 2014-19-02 Paulo Andrade <pcpa@gnu.org> |
| 1835 | |
| 1836 | * lib/jit_x86.c: Rewrite incorrect inline assembly that could |
| 1837 | truncate a variable in a callee save register. Now it simply |
| 1838 | tells gcc that the register is clobbered, instead of using a |
| 1839 | *32 bit* swap with a temporary variable. The problem only |
| 1840 | happens when compiling with optimization. |
| 1841 | |
| 1842 | 2014-19-02 Paulo Andrade <pcpa@gnu.org> |
| 1843 | |
| 1844 | * include/lightning/jit_aarch64.h, include/lightning/jit_arm.h, |
| 1845 | include/lightning/jit_hppa.h, include/lightning/jit_ia64.h, |
| 1846 | include/lightning/jit_mips.h, include/lightning/jit_ppc.h, |
| 1847 | include/lightning/jit_s390x.h, include/lightning/jit_sparc.h, |
| 1848 | include/lightning/jit_x86.h: Change jit_regset_t to an |
| 1849 | unsigned type, to allow safe right shift. |
| 1850 | |
| 1851 | * lib/lightning.c: Rewrite jit_regset_scan1 to allow easier |
| 1852 | compiler optimization. |
| 1853 | |
| 1854 | 2013-12-03 Paulo Andrade <pcpa@gnu.org> |
| 1855 | |
| 1856 | * lib/jit_x86-x87.c: Correct wrong optimization when |
| 1857 | loading the log(2) constant. |
| 1858 | |
| 1859 | 2013-12-03 Paulo Andrade <pcpa@gnu.org> |
| 1860 | |
| 1861 | * lib/jit_x86-cpu.c: Use the emms instruction before |
| 1862 | calling any function. This is particularly important |
| 1863 | when using c99 complex functions as it can easily |
| 1864 | overflow the x87 stack due to the way lightning uses |
| 1865 | the x87 stack as a flat register file. |
| 1866 | |
| 1867 | 2013-12-02 Paulo Andrade <pcpa@gnu.org> |
| 1868 | |
| 1869 | * lib/jit_x86-x87.c: Correct wrong code generation due |
| 1870 | to comparing the base and not the value register with |
| 1871 | %st(0) in stxi_f. |
| 1872 | |
| 1873 | 2013-12-02 Paulo Andrade <pcpa@gnu.org> |
| 1874 | |
| 1875 | * lib/jit_x86-x87.c, lib/jit_x86.c: Use 8 bytes aligned |
| 1876 | stack offset for float/double x87 to/from sse move. |
| 1877 | |
| 1878 | 2013-11-27 Paulo Andrade <pcpa@gnu.org> |
| 1879 | |
| 1880 | * configure.ac, lib/jit_arm-swf.c, lib/jit_arm.c: Add |
| 1881 | changes that should at least allow building lightning |
| 1882 | on Apple iOS7. |
| 1883 | |
| 1884 | 2013-10-08 Paulo Andrade <pcpa@gnu.org> |
| 1885 | |
| 1886 | * lib/jit_ppc-cpu.c: Correct wrong shortcut for ldxi_l with |
| 1887 | a zero offset, that was calling ldr_i instead of ldr_l. |
| 1888 | |
| 1889 | 2013-10-08 Paulo Andrade <pcpa@gnu.org> |
| 1890 | |
| 1891 | * include/lightning/jit_arm.h, lib/jit_arm-cpu.c: Do not use |
| 1892 | by default load/store instructions that map to ldrt/strt. |
| 1893 | There is already the long displacement version for positive |
| 1894 | offsets, and when using a (shorter) negative offset it does |
| 1895 | not map to ldrt/strt. At least on qemu strt may cause |
| 1896 | reproducible, but unexpected SIGILL. |
| 1897 | |
| 1898 | 2013-10-08 Paulo Andrade <pcpa@gnu.org> |
| 1899 | |
| 1900 | * lib/jit_arm-vfp.c: Correct wrong load/store offset |
| 1901 | calculation when the displacement is constant but too |
| 1902 | large to use an instruction with an immediate offset. |
| 1903 | |
| 1904 | 2013-10-07 Paulo Andrade <pcpa@gnu.org> |
| 1905 | |
| 1906 | * check/self.c: Extend tests to validate jit_callee_save_p |
| 1907 | does not cause an assertion on valid arguments, and test |
| 1908 | extra registers defined on some backends. |
| 1909 | |
| 1910 | * configure.ac: Do not ignore environment CFLAGS when |
| 1911 | checking if need to test runtime configurable options, |
| 1912 | like use x87 when sse2 is available, arm instruction set |
| 1913 | instead of thumb, etc. |
| 1914 | |
| 1915 | * include/lightning/jit_arm.h: Correct wrong jit_f macro |
| 1916 | definition. |
| 1917 | |
| 1918 | * include/lightning/jit_ia64.h, include/lightning/jit_ppc.h: |
| 1919 | Correct wrong jit_r macro definition. |
| 1920 | |
| 1921 | * lib/jit_x86-x87.c, lib/jit_x86.c: Actually use the |
| 1922 | reserved stack space for integer to/from float conversion. |
| 1923 | The stack space was also changed to ensure it is 8 bytes |
| 1924 | aligned. Also, for Solaris x86 in 32 bit mode, an alternate |
| 1925 | truncr_d was implemented because for some reason it is |
| 1926 | failing with SIGILL if using the "fisttpl" instructions, |
| 1927 | that must be available on p6 or newer, but for the sake of |
| 1928 | making all tests pass, implement a 486 or newer sequence |
| 1929 | if "sun" is defined. |
| 1930 | |
| 1931 | 2013-10-03 Paulo Andrade <pcpa@gnu.org> |
| 1932 | |
| 1933 | * include/lightning/jit_mips.h, lib/jit_mips-cpu.c, |
| 1934 | lib/jit_mips-sz.c, lib/jit_mips.c, size: Build and |
| 1935 | pass all test cases on Irix big endian mips using |
| 1936 | the 64 bit abi. |
| 1937 | |
| 1938 | 2013-10-02 Paulo Andrade <pcpa@gnu.org> |
| 1939 | |
| 1940 | * include/lightning/jit_mips.h: Add proper mips abi detection. |
| 1941 | |
| 1942 | 2013-09-30 Paulo Andrade <pcpa@gnu.org> |
| 1943 | |
| 1944 | * lib/jit_print.c: Do not crash if calling jit_print from |
| 1945 | gdb before actually emitting code. |
| 1946 | |
| 1947 | * lib/lightning.c: Correct misplaced check for already |
| 1948 | visited blocks on conditional branches, what was preventing |
| 1949 | proper merge live bit masks of forward blocks. |
| 1950 | |
| 1951 | 2013-09-30 Paulo Andrade <pcpa@gnu.org> |
| 1952 | |
| 1953 | * lib/jit_x86-cpu.c: Correct not properly tested case of using |
| 1954 | %r12 as index register, what was causing an invalid assertion. |
| 1955 | %r12 is mapped to the "extra" JIT_R3 register, and test cases |
| 1956 | only test "standard" lightning registers. |
| 1957 | |
| 1958 | 2013-09-28 Paulo Andrade <pcpa@gnu.org> |
| 1959 | |
| 1960 | * lib/jit_ia64.c: Minor change to force collecting the maximum |
| 1961 | instruction length in the --enable-devel-get-jit-size build |
| 1962 | mode. The actual generated file did not change because the |
| 1963 | sampling was large enough that it had already collected proper |
| 1964 | information in the previously slightly buggy code (not forcing |
| 1965 | a sync of the instructions that could be combined). |
| 1966 | |
| 1967 | 2013-09-27 Paulo Andrade <pcpa@gnu.org> |
| 1968 | |
| 1969 | * lib/jit_arm.c: Correct build when disassembler is |
| 1970 | disabled. |
| 1971 | |
| 1972 | 2013-09-25 Paulo Andrade <pcpa@gnu.org> |
| 1973 | |
| 1974 | * lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c: Correct some |
| 1975 | off by one range checks (that were only accepting values |
| 1976 | one less than the maximum allowed) and an invalid test |
| 1977 | condition check that was forcing it to always use |
| 1978 | indirect jumps even when reachable with an immediate |
| 1979 | displacement. |
| 1980 | |
| 1981 | 2013-09-24 Paulo Andrade <pcpa@gnu.org> |
| 1982 | |
| 1983 | * lib/jit_aarch64-sz.c, lib/jit_arm-sz.c, lib/jit_hppa-sz.c, |
| 1984 | lib/jit_ia64-sz.c, lib/jit_mips-sz.c, lib/jit_ppc-sz.c, |
| 1985 | lib/jit_s390x-sz.c, lib/jit_size.c, lib/jit_sparc-sz.c, |
| 1986 | lib/jit_x86-sz.c: New files implementing static tables |
| 1987 | with longest known instructions length generated to match |
| 1988 | a lightning instruction. These tables should make it easier |
| 1989 | to make it very unlikely to ever miscalculate, or by too |
| 1990 | much, the size of a code buffer. |
| 1991 | |
| 1992 | * lib/jit_size.c: New file that aids to either collect |
| 1993 | jit code size information, or use the information depending |
| 1994 | on build options. |
| 1995 | |
| 1996 | * size.c: New helper file that parses input for, and create |
| 1997 | an initial jit_$arch-sz.c file, that needs some minor edit |
| 1998 | for arches with multiple configurations. |
| 1999 | |
| 2000 | * configure.ac, Makefile.am: Add the new, devel mode only |
| 2001 | --enable-devel-get-jit-size configure option, that sets |
| 2002 | compile time flags to collect jit code size information, |
| 2003 | that will be used as input for the "noinst size program". |
| 2004 | |
| 2005 | * lib/jit_aarch64.c, lib/jit_arm.c, lib/jit_disasm.c, |
| 2006 | lib/jit_hppa.c, lib/jit_ia64.c, lib/jit_memory.c, |
| 2007 | lib/jit_mips.c, lib/jit_ppc.c, lib/jit_s390x.c, |
| 2008 | lib/jit_sparc.c, lib/jit_x86.c, lib/lightning.c: Minor |
| 2009 | changes for the --enable-devel-get-jit-size build mode, |
| 2010 | as well as the "production build mode" with jit code |
| 2011 | size information. |
| 2012 | |
| 2013 | 2013-09-14 Paulo Andrade <pcpa@gnu.org> |
| 2014 | |
| 2015 | * include/lightning.h, lib/lightning.c: Add the new |
| 2016 | jit_pointer_p interface, that returns a boolean value |
| 2017 | telling if the pointer argument is inside the jit |
| 2018 | code buffer. This is useful to avoid the need to add |
| 2019 | extra labels and calls to jit_address to figure bounds |
| 2020 | of code buffer, and still keep internal data private. |
| 2021 | |
| 2022 | 2013-09-13 Paulo Andrade <pcpa@gnu.org> |
| 2023 | |
| 2024 | * include/lightning.h, include/lightning/jit_private.h, |
| 2025 | lib/jit_note.c: Change the code argument of jit_get_note |
| 2026 | to a jit_pointer_t and make jit_get_note a public interface. |
| 2027 | It was intended so since start, as a way to map an offset |
| 2028 | in the code to a function name, file name and line number |
| 2029 | mapping. |
| 2030 | |
| 2031 | 2013-09-11 Paulo Andrade <pcpa@gnu.org> |
| 2032 | |
| 2033 | * doc/body.texi: Correct reversed arguments in example of |
| 2034 | usage in a (possibly) multi threaded, multiple jit_state_t |
| 2035 | environments. |
| 2036 | |
| 2037 | * include/lightning/jit_arm.h, include/lightning/jit_private.h, |
| 2038 | lib/jit_arm-cpu.c, lib/jit_arm.c: Make a previously, non |
| 2039 | documented, global state private to the related jit_state_t |
| 2040 | generating code. |
| 2041 | |
| 2042 | 2013-09-10 Paulo Andrade <pcpa@gnu.org> |
| 2043 | |
| 2044 | * check/self.c, check/self.ok: New files implementing simple |
| 2045 | consistency check assertions. At first validating some macros |
| 2046 | that use values from different sources agree. |
| 2047 | |
| 2048 | * check/Makefile.am: Update for the new test case. |
| 2049 | |
| 2050 | * include/lightning.h, lib/lightning.c: Add the new |
| 2051 | jit_callee_save_p() call, that is intended to be used when |
| 2052 | writing complex code using lightning, so that one does not |
| 2053 | need to verify what backend is being used, or have access to |
| 2054 | private data, to query if a register is callee save or not; |
| 2055 | on several backends the scratch registers are actually callee |
| 2056 | save. |
| 2057 | |
| 2058 | * include/lightning/jit_aarch64.h, include/lightning/jit_arm.h, |
| 2059 | include/lightning/jit_hppa.h, include/lightning/jit_mips.h, |
| 2060 | include/lightning/jit_ppc.h, include/lightning/jit_sparc.h, |
| 2061 | include/lightning/jit_x86.h: Add an explicit definition for |
| 2062 | JIT_R3-JIT_Rn, JIT_V3-JIT_Vn and JIT_F6-JIT_Fn when applicable. |
| 2063 | This allows one to write code based on "#if defined(JIT_XN)" |
| 2064 | and therefore, not need to check what is the current backend |
| 2065 | or have access to private data structures. This is particularly |
| 2066 | useful when writing virtual machines with several specialized, |
| 2067 | global registers. |
| 2068 | |
| 2069 | * lib/jit_ia64.c: Properly flag the callee save general |
| 2070 | purpose registers as such, so that jit_callee_save_p() works |
| 2071 | as intended. |
| 2072 | |
| 2073 | 2013-09-10 Paulo Andrade <pcpa@gnu.org> |
| 2074 | |
| 2075 | * check/lightning.c, configure.ac: Conditionally use the |
| 2076 | code written to workaround a bug in the Hercules emulator, |
| 2077 | as isnan and isinf are not available at least on HP-UX ia64. |
| 2078 | |
| 2079 | 2013-09-10 Paulo Andrade <pcpa@gnu.org> |
| 2080 | |
| 2081 | * lib/jit_s390x-cpu.c: Spill/reload correct callee save |
| 2082 | float registers. |
| 2083 | |
| 2084 | 2013-09-10 Paulo Andrade <pcpa@gnu.org> |
| 2085 | |
| 2086 | * lib/jit_hppa-cpu.c: Correct code to call a function stored |
| 2087 | in a register or a patched function address. |
| 2088 | |
| 2089 | 2013-09-10 Paulo Andrade <pcpa@gnu.org> |
| 2090 | |
| 2091 | * lib/jit_ia64-cpu.c: Correct incorrect logic when restoring |
| 2092 | the value of the "r2" callee save register. |
| 2093 | |
| 2094 | 2013-08-29 Paulo Andrade <pcpa@gnu.org> |
| 2095 | |
| 2096 | * lib/jit_arm-cpu.c, lib/jit_arm.c: Correct wrong test and update |
| 2097 | of the thumb offset information, when checking if needing to |
| 2098 | patch a jump from arm to thumb mode. The problem would happen when |
| 2099 | remapping the code buffer, and the new address being lower than |
| 2100 | the previous one. |
| 2101 | |
| 2102 | 2013-08-26 Paulo Andrade <pcpa@gnu.org> |
| 2103 | |
| 2104 | * configure.ac: Extend FreeBSD test to also handle NetBSD. |
| 2105 | |
| 2106 | * lib/jit_x86-cpu.c: Correct wrongly defined offset type of |
| 2107 | ldxi_ui. Problem detected when building on NetBSD. |
| 2108 | |
| 2109 | * lib/lightning.c: Adjust code to handle NetBSD mremap, |
| 2110 | where arguments do not match Linux mremap. |
| 2111 | |
| 2112 | 2013-08-26 Paulo Andrade <pcpa@gnu.org> |
| 2113 | |
| 2114 | * lib/jit_ppc.c: Correct C sequence point problem miscalculating |
| 2115 | the actual function address in a function descriptor. Problem |
| 2116 | happens with gcc 4.8.1 at least. |
| 2117 | |
| 2118 | 2013-08-11 Paulo Andrade <pcpa@gnu.org> |
| 2119 | |
| 2120 | * lib/jit_s390x-cpu.c: Correct code checking if immediate |
| 2121 | fits instruction, but using the negated value. |
| 2122 | |
| 2123 | 2013-07-28 Paulo Andrade <pcpa@gnu.org> |
| 2124 | |
| 2125 | * include/lightning/jit_s390x.h, lib/jit_s390x-cpu.c, |
| 2126 | lib/jit_s390x-fpu.c, lib/jit_s390x.c: New files |
| 2127 | implementing the new s390x port. |
| 2128 | |
| 2129 | * configure.ac, include/lightning.h, |
| 2130 | include/lightning/Makefile.am, |
| 2131 | include/lightning/jit_private.h, |
| 2132 | lib/Makefile.am, lib/jit_disasm.c, lib/lightning.c: |
| 2133 | Minor adaptation for the new s390x backend. |
| 2134 | |
| 2135 | * check/float.tst: Update for the s390x result of |
| 2136 | truncating +Inf to integer. |
| 2137 | |
| 2138 | * check/qalu_mul.tst: Add extra test cases to better test |
| 2139 | high word of signed multiplication as the result is |
| 2140 | adjust from unsigned multiplication on s390x. |
| 2141 | |
| 2142 | 2013-07-28 Paulo Andrade <pcpa@gnu.org> |
| 2143 | |
| 2144 | * check/lightning.c: Do not assume casting a double NaN or |
| 2145 | Inf to float will produce the expected float NaN or Inf. |
| 2146 | This is not true at least under s390x. |
| 2147 | |
| 2148 | 2013-07-28 Paulo Andrade <pcpa@gnu.org> |
| 2149 | |
| 2150 | * check/check.arm.sh, check/check.sh, check/check.swf.sh, |
| 2151 | check/check.x87.sh: Properly check test programs output, |
| 2152 | not just rely on the test program self testing the results |
| 2153 | and not crashing. |
| 2154 | |
| 2155 | 2013-07-28 Paulo Andrade <pcpa@gnu.org> |
| 2156 | |
| 2157 | * lib/jit_aarch64.c: Remove unused macros left from cut&paste |
| 2158 | of jit_arm.c. |
| 2159 | |
| 2160 | 2013-07-16 Paulo Andrade <pcpa@gnu.org> |
| 2161 | |
| 2162 | * include/lightning/jit_aarch64.h, lib/jit_aarch64-cpu.c, |
| 2163 | lib/jit_aarch64-fpu.c, lib/jit_aarch64.c: New files |
| 2164 | implementing the new aarch64 port, as a new architecture, |
| 2165 | not as an expansion of the existing armv[4-7] port. |
| 2166 | |
| 2167 | * check/lightning.c: Add aarch64 support and a small |
| 2168 | change to recognize character constants as immediate |
| 2169 | values. |
| 2170 | |
| 2171 | * check/float.tst: Add aarch64 preprocessor conditionals |
| 2172 | to select proper expected value when converting [+-]Inf |
| 2173 | and NaN to integer. |
| 2174 | |
| 2175 | * include/lightning/jit_arm.h, lib/jit_arm.c: Minor changes |
| 2176 | to better match the new aarch64 files. |
| 2177 | |
| 2178 | * configure.ac, include/lightning.h, |
| 2179 | include/lightning/Makefile.am, include/lightning/jit_private.h, |
| 2180 | lib/Makefile.am, lib/lightning.c: Minor adjustments |
| 2181 | for the aarch64 port. |
| 2182 | |
| 2183 | 2013-07-08 Paulo Andrade <pcpa@gnu.org> |
| 2184 | |
| 2185 | * NEWS, THANKS, configure.ac, doc/version.texi: Update for |
| 2186 | the 1.99a second alpha release. |
| 2187 | |
| 2188 | 2013-06-25 Paulo Andrade <pcpa@gnu.org> |
| 2189 | |
| 2190 | * lib/jit_mips.c: Correct cut&paste error that caused wrong |
| 2191 | stack offset calculation for double arguments in stack in |
| 2192 | the o32 abi. |
| 2193 | Correct typo in the __LITTLE_ENDIAN macro name, that came |
| 2194 | from cut&paste error in the original typo in lib/jit_ppc.c. |
| 2195 | |
| 2196 | * lib/jit_ia64.c, lib/jit_ppc.c: Correct typo in the |
| 2197 | __LITTLE_ENDIAN macro name. |
| 2198 | |
| 2199 | 2013-06-22 Paulo Andrade <pcpa@gnu.org> |
| 2200 | |
| 2201 | * check/lightning.c, configure.ac, include/lightning.h, |
| 2202 | lib/lightning.c: Add tests and quirks to build/detect |
| 2203 | and/or work on Irix. |
| 2204 | |
| 2205 | * include/lightning/jit_mips.h, lib/jit_mips-cpu.c, |
| 2206 | lib/jit_mips-fpu.c, lib/jit_mips.c: Adapt code to run |
| 2207 | in big endian mips, using the n32 abi. |
| 2208 | |
| 2209 | 2013-06-18 Paulo Andrade <pcpa@gnu.org> |
| 2210 | |
| 2211 | * include/lightning.h: Minor extra preprocessor testing |
| 2212 | to "detect" byte order on x86 solaris, that now builds |
| 2213 | and pass all test cases. |
| 2214 | |
| 2215 | 2013-06-18 Paulo Andrade <pcpa@gnu.org> |
| 2216 | |
| 2217 | * lib/jit_sparc-cpu.c: Correct compiler warning of value |
| 2218 | used before assignment. The usage is bogus as the api |
| 2219 | requires always patching jumps, but the random value used |
| 2220 | could cause an assertion due to invalid displacement. |
| 2221 | |
| 2222 | * lib/jit_sparc.c: Always load and store double arguments |
| 2223 | in stack as 2 float loads or stores, for safety, as unaligned |
| 2224 | access is not allowed in Sparc Solaris. |
| 2225 | |
| 2226 | 2013-06-14 Paulo Andrade <pcpa@gnu.org> |
| 2227 | |
| 2228 | * configure.ac: Force -mlp64 to CFLAGS on HP-UX ia64 port. |
| 2229 | It is the only supported mode, and expects gcc as C compiler. |
| 2230 | |
| 2231 | * include/lightning.h, lib/jit_ia64-cpu.c, lib/jit_ia64.c: |
| 2232 | Correct ia64 port to work on HP-UX that runs it in big endian |
| 2233 | mode. |
| 2234 | |
| 2235 | 2013-06-10 Paulo Andrade <pcpa@gnu.org> |
| 2236 | |
| 2237 | * lib/jit_hppa.c: Sanitize the cache synchronization inline |
| 2238 | assembly code that was doing twice the work and redundantly |
| 2239 | flushing the end address every loop iteration. |
| 2240 | |
| 2241 | 2013-06-09 Paulo Andrade <pcpa@gnu.org> |
| 2242 | |
| 2243 | * configure.ac, check/Makefile.am, doc/Makefile.am: Do not |
| 2244 | explicitly link to -ldl, but instead autodetect the library |
| 2245 | with dlopen, dlsym, etc. |
| 2246 | |
| 2247 | * check/lightning.c: Add workaround to apparently buggy |
| 2248 | getopt in HP-UX that sets optind to the wrong index, and |
| 2249 | use RTLD_NEXT on HP-UX instead of RTLD_DEFAULT to dlsym |
| 2250 | global symbols. |
| 2251 | |
| 2252 | * include/lightning.h: Rework definitions of wordsize and |
| 2253 | byte order to detect proper values on HP-UX. |
| 2254 | |
| 2255 | * lib/lightning.c: Minor correction to use MAP_ANONYMOUS |
| 2256 | instead of MAP_ANON on HP-UX. |
| 2257 | |
| 2258 | * lib/jit_hppa.c: Float arguments must be passed on integer |
| 2259 | registers on HP-UX, not only for varargs functions. |
| 2260 | Add code to properly clear instruction cache. This was |
| 2261 | not required on Debian hppa port, but may have been working |
| 2262 | by accident. |
| 2263 | |
| 2264 | * lib/jit_hppa-cpu.c: Follow pattern of HP-UX binaries and |
| 2265 | use bve,n instead of bv,n to return from functions. |
| 2266 | |
| 2267 | * lib/jit_hppa-fpu.c: For some reason "fst? frX,rX,(rY)" did |
| 2268 | not work on the tested computer (HP-UX B.11.23 U 9000/785 HP-UX) |
| 2269 | so the code was changed, at first for __hpux only to add the |
| 2270 | base and offset register and use the instruction with an |
| 2271 | immediate (zero) offset. |
| 2272 | |
| 2273 | 2013-06-07 Paulo Andrade <pcpa@gnu.org> |
| 2274 | |
| 2275 | * check/lightning.c, lib/jit_disasm.c, lib/jit_ppc-cpu.c, |
| 2276 | lib/jit_ppc-fpu.c, lib/jit_ppc.c, include/lightning.h, |
| 2277 | include/lightning/jit_ppc.h, include/lightning/jit_private.h: |
| 2278 | Adapt code to work on 32 bit AIX ppc using gcc. Most changes |
| 2279 | are basically to adapt the elf64 logic to 32 bit, as it does |
| 2280 | not use the same convention of 32 bit Darwin ppc. |
| 2281 | |
| 2282 | * check/stack.tst: Add a fake memcpy function to the test |
| 2283 | case if running under AIX, as it is not available to dlsym. |
| 2284 | |
| 2285 | * configure.ac: Check for getopt.h header, not available in |
| 2286 | AIX. |
| 2287 | |
| 2288 | 2013-06-01 Paulo Andrade <pcpa@gnu.org> |
| 2289 | |
| 2290 | * include/lightning/jit_hppa.h, lib/jit_hppa-cpu.c, |
| 2291 | lib/jit_hppa-fpu.c, lib/jit_hppa.c: New files implementing |
| 2292 | the hppa port. Built on Debian Linux PA-RISC 2.0, 32 bit. |
| 2293 | |
| 2294 | * check/float.tst: Add preprocessor for hppa expected |
| 2295 | values when converting NaN and +-Inf to an integer. |
| 2296 | |
| 2297 | * check/ldst.inc: Ensure double load/store tests use an |
| 2298 | 8 byte aligned address by default. |
| 2299 | |
| 2300 | * lib/lightning.c: Correct a bug found during tests in |
| 2301 | the new port, where qmul* and qdiv* were not properly |
| 2302 | setting one of the result registers as modified in the |
| 2303 | function, what would be a problem if the only "write" |
| 2304 | usage were the qmul* or qdiv*. |
| 2305 | |
| 2306 | * check/varargs.tst, check/varargs.ok: Add one extra |
| 2307 | interleaved integer/double test to validate proper code |
| 2308 | generation in the extra case. |
| 2309 | |
| 2310 | * check/lightning.c, configure.ac, include/lightning.h, |
| 2311 | include/lightning/Makefile.am, |
| 2312 | include/lightning/jit_private.h, lib/Makefile.am, |
| 2313 | lib/jit_disasm.c: Update for the hppa port. |
| 2314 | |
| 2315 | 2013-04-27 Paulo Andrade <pcpa@gnu.org> |
| 2316 | |
| 2317 | * check/varargs.tst: Correct misplaced .align directive |
| 2318 | that was causing the double buffer to not be aligned at |
| 2319 | 8 bytes. |
| 2320 | * lib/jit_ia64-cpu.c: |
| 2321 | Properly implement abi for excess arguments passed on |
| 2322 | stack. |
| 2323 | Simplify load/store with immediate displacement argument |
| 2324 | with zero value. |
| 2325 | Simplify some calls to "subi" changing to "addi" with |
| 2326 | a negative argument. |
| 2327 | Remove some #if 0'ed code, that could be useful in |
| 2328 | special conditions, but the most useful one would be |
| 2329 | to "optimize" "static" jit functions, but for the sake |
| 2330 | of simplicity, jit functions are implemented in a way |
| 2331 | that can be passed back to C code as C function pointers. |
| 2332 | Add an attribute to prototypes of several unused functions. |
| 2333 | These functions are defined for the sake of implementing all |
| 2334 | Itanium documented instructions, but a significant amount of |
| 2335 | them is not used by lightning. |
| 2336 | * lib/jit_ia64-fpu.c: Simplify load/store with zero immediate |
| 2337 | displacement and add unused attribute for functions not used |
| 2338 | by lightning, but required to provide macros implementing all |
| 2339 | Itanium documented instructions. |
| 2340 | * lib/jit_ia64.c: Update for the properly implemented abi |
| 2341 | for stack arguments. |
| 2342 | * lib/lightning.c: Mark an unused function as such. |
| 2343 | |
| 2344 | 2013-04-27 Paulo Andrade <pcpa@gnu.org> |
| 2345 | |
| 2346 | lib/jit_ia64-cpu.c: |
| 2347 | Correct immediate range check of integer comparisons when |
| 2348 | inverting arguments. |
| 2349 | Correct gei_u that was not decrementing immediate when |
| 2350 | inverting arguments. |
| 2351 | Correct b?add* and b?sub* that were not properly updating |
| 2352 | the result register. |
| 2353 | |
| 2354 | 2013-04-27 Paulo Andrade <pcpa@gnu.org> |
| 2355 | |
| 2356 | * lib/jit_ia64-cpu.c: Correct wrong mapping of 2 instructions |
| 2357 | in "M-, stop, M-, stop" translation, that was ignoring the |
| 2358 | last stop (implemented as a nop I- stop). |
| 2359 | |
| 2360 | * lib/jit_ia64-fpu.c: Properly implement fnorm.s and fnorm.d, |
| 2361 | as well as the proper integer to float or double conversion. |
| 2362 | |
| 2363 | 2013-04-27 Paulo Andrade <pcpa@gnu.org> |
| 2364 | |
| 2365 | * lib/jit_ia64-cpu.c: Correct bogus implementation of ldr_T |
| 2366 | for signed integers, that was using ld1.s, ld2.s and ld4.s. |
| 2367 | The ".s" stands for speculative load, not sign extend. |
| 2368 | |
| 2369 | * lib/jit_ia64-fpu.c: Correct bogus implementation of ldxr_T |
| 2370 | for float and double. The third (actually, second) argument |
| 2371 | is indeed added to the base register, but the base register |
| 2372 | is modified. The actual M7 implementation was already correct, |
| 2373 | just the ldxr_f and ldxr_d implementation that was kept in |
| 2374 | a prototype state, misinterpreting what M7 does. |
| 2375 | |
| 2376 | 2013-04-27 Paulo Andrade <pcpa@gnu.org> |
| 2377 | |
| 2378 | * lib/jit_ia64-cpu.c: Correct X2 pattern matching by preventing |
| 2379 | it to attempt to require a stop between the L and the X |
| 2380 | instruction; that is, check the registers and predicates |
| 2381 | before emitting the L instruction, not after. |
| 2382 | |
| 2383 | * lib/jit_ia64-fpu.c: Slightly simplify and correct |
| 2384 | divr_f and divrd_d implementation. |
| 2385 | |
| 2386 | * check/lightning.c: Add __ia64__ preprocessor define |
| 2387 | on Itanium. |
| 2388 | |
| 2389 | * check/alu.inc, check/clobber.tst, check/float.tst: Define |
| 2390 | several macros conditionally to __ia64__. This is required |
| 2391 | because __ia64__ jit generation can use way too many memory, |
| 2392 | due to not implementing instruction reordering to avoid |
| 2393 | as much as possible "stops", what causes way too many nops |
| 2394 | to be generated, as well as the fact that division and |
| 2395 | remainder requires function calls, and float division |
| 2396 | requires significant code to implement. |
| 2397 | |
| 2398 | 2013-04-27 Paulo Andrade <pcpa@gnu.org> |
| 2399 | |
| 2400 | * include/lightning.h: Add new backend specific movr_w_d, |
| 2401 | movr_d_w and movi_d_w codes as helpers to ia64 varargs |
| 2402 | functions arguments. |
| 2403 | |
| 2404 | * lib/jit_ia64-cpu.c: |
| 2405 | Correct wrong encoding of A5 small integers. |
| 2406 | Correct define of "mux" instruction modifiers. |
| 2407 | Correct ordering of arguments and predicates of cmp_xy |
| 2408 | implementation with immediate arguments; like most other |
| 2409 | codes with an immediate, the immediate is the second, not |
| 2410 | the third argument. |
| 2411 | |
| 2412 | * lib/jit_ia64-fpu.c: Actual implementation of the code |
| 2413 | to move to/from gpr to/from fpr, to implement varargs abi. |
| 2414 | |
| 2415 | * lib/jit_ia64.c: Make fpr argument registers not allocatable |
| 2416 | as temporaries, no need for the extra checks when there are |
| 2417 | plenty registers. |
| 2418 | |
| 2419 | * lib/jit_print.c, lib/lightning.c: Minor updates for the |
| 2420 | new movr_w_d, movr_d_w and movi_d_w codes. |
| 2421 | |
| 2422 | 2013-04-26 Paulo Andrade <pcpa@gnu.org> |
| 2423 | |
| 2424 | * lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c: Correct code to |
| 2425 | also insert a stop to break an instruction group if a |
| 2426 | register is written more than once in the same group. |
| 2427 | This may happen if a register is argument and result of |
| 2428 | some lightning call (not a real instruction). The most |
| 2429 | common case should be code in the pattern: |
| 2430 | movl rn=largenum |
| 2431 | ... |
| 2432 | mov rn=smallnum |
| 2433 | where "rn" would end up holding "largenum". |
| 2434 | But the problem possibly could happen in other circumstances. |
| 2435 | |
| 2436 | 2013-04-26 Paulo Andrade <pcpa@gnu.org> |
| 2437 | |
| 2438 | * include/lightning/jit_ia64.h, lib/jit_ia64-cpu.c, |
| 2439 | lib/jit_ia64-fpu.c, lib/jit_ia64.c: |
| 2440 | Relocate JIT_Rn registers to the local registers, as, like |
| 2441 | float registers, div/rem and sqrt are implemented as function |
| 2442 | calls, and may overwrite non saved scratch registers. |
| 2443 | Change patch_at to receive a jit_code_t instead of a |
| 2444 | jit_node_t, so that it is easier to "inline" patches when |
| 2445 | some instruction requires complex code to implement, e.g. |
| 2446 | uneq and ltgt. |
| 2447 | Correct arguments to FMA and FMA like instructions that, |
| 2448 | due to a cut&paste error were passing the wrong argument |
| 2449 | to the related F- implementation function. |
| 2450 | Rewrite ltgt to return the proper result if one (or both) |
| 2451 | of the arguments is unordered. |
| 2452 | |
| 2453 | 2013-04-26 Paulo Andrade <pcpa@gnu.org> |
| 2454 | |
| 2455 | * include/lightning/jit_ia64.h, include/lightning/jit_private.h, |
| 2456 | lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c, lib/jit_ia64.c, |
| 2457 | lib/lightning.c: Rework code to detect need of a "stop" to |
| 2458 | also handle predicates, as if a predicate is written, it |
| 2459 | cannot be read in the same instruction group. |
| 2460 | Use a single jit_regset_t variable for all registers when |
| 2461 | checking need for a stop (increment value by 128 for |
| 2462 | float registers). |
| 2463 | Correct wrong "subi" implementation, as the code executed |
| 2464 | is r0=im-r1, not r0=r1-im. |
| 2465 | Use standard lightning 6 fpr registers, and rework to |
| 2466 | use callee save float registers, that may be spill/reloaded |
| 2467 | in prolog/epilog. This is required because some jit |
| 2468 | instructions implementations need to call functions; currently |
| 2469 | integer div/mod and float sqrt, what may change the value of |
| 2470 | scratch float registers. |
| 2471 | Rework point of "sync" of branches that need to return a |
| 2472 | patch'able address, because the need for a "stop" before a |
| 2473 | predicate read causes all branches to be the instruction |
| 2474 | in slot 0, as there is no template to "stop" and branch |
| 2475 | in the same instruction "bundle". |
| 2476 | |
| 2477 | 2013-04-25 Paulo Andrade <pcpa@gnu.org> |
| 2478 | |
| 2479 | * include/lightning/jit_ia64.h, lib/jit_ia64-cpu.c, |
| 2480 | lib/jit_ia64-fpu.c, lib/jit_ia64.c: New files implementing |
| 2481 | the basic infrastructure of an Itanium port. The code |
| 2482 | compiles and can generate jit for basic hello world like |
| 2483 | functions. |
| 2484 | |
| 2485 | * check/lightning.c, configure.ac, include/lightning.h, |
| 2486 | include/lightning/Makefile.am, include/lightning/jit_private.h, |
| 2487 | lib/Makefile.am, lib/lightning.c: Update for the Itanium |
| 2488 | port. |
| 2489 | |
| 2490 | * lib/jit_mips-cpu.c, lib/jit_mips.c: Correct typo and |
| 2491 | make the jit_carry register local to the jit_state_t. |
| 2492 | This matches code reviewed in the Itanium port, that |
| 2493 | should use the same base logic to handle carry/borrow. |
| 2494 | |
| 2495 | 2013-04-10 Paulo Andrade <pcpa@gnu.org> |
| 2496 | |
| 2497 | * include/lightning/jit_private.h, lib/jit_arm.c, |
| 2498 | lib/jit_mips-cpu.c, lib/jit_mips.c, lib/jit_ppc-cpu.c, |
| 2499 | lib/jit_ppc.c, lib/jit_print.c, lib/jit_sparc-cpu.c, |
| 2500 | lib/jit_sparc.c, lib/jit_x86-cpu.c, lib/jit_x86.c, |
| 2501 | lib/lightning.c: Change all jit_regset macros to take |
| 2502 | a pointer argument, to avoid structure copies when |
| 2503 | adding a port to an architecture with more than 64 |
| 2504 | registers. |
| 2505 | |
| 2506 | 2013-04-08 Paulo Andrade <pcpa@gnu.org> |
| 2507 | |
| 2508 | * lib/jit_arm.c, lib/jit_ppc.c: Do not rely on __clear_cache |
| 2509 | aligning to the next page boundary the end argument. It may |
| 2510 | actually truncate it. |
| 2511 | |
| 2512 | 2013-03-29 Paulo Andrade <pcpa@gnu.org> |
| 2513 | |
| 2514 | * include/lightning/jit_private.h, lib/jit_arm.c, lib/jit_memory.c, |
| 2515 | lib/jit_mips.c, lib/jit_ppc.c, lib/jit_sparc.c, lib/jit_x86.c, |
| 2516 | lib/lightning.c: Do not start over jit generation if can grow |
| 2517 | the code buffer with mremap without moving the base pointer. |
| 2518 | |
| 2519 | 2013-03-29 Paulo Andrade <pcpa@gnu.org> |
| 2520 | |
| 2521 | * lib/jit_memory.c: Implement a simple memory allocation wrapper |
| 2522 | to allow overriding calls to malloc/calloc/realloc/free, as well |
| 2523 | as ensuring all memory containing pointers is zero or points to |
| 2524 | allocated memory. |
| 2525 | |
| 2526 | * include/lightning.h, include/lightning/jit_private.h: Definitions |
| 2527 | for the memory allocation wrapper. |
| 2528 | |
| 2529 | * lib/Makefile.am: Update for new jit_memory.c file. |
| 2530 | |
| 2531 | * lib/jit_arm.c, lib/jit_disasm.c, lib/jit_mips.c, lib/jit_note.c, |
| 2532 | lib/jit_ppc.c, lib/jit_sparc.c, lib/jit_x86.c, lib/lightning.c: |
| 2533 | Use the new memory allocation wrapper code. |
| 2534 | |
| 2535 | 2013-03-22 Paulo Andrade <pcpa@gnu.org> |
| 2536 | |
| 2537 | * configure.ac, include/lightning/jit_private.h, lib/lightning.c: |
| 2538 | Remove dependency on gmp. Only a simple bitmap was required, and |
| 2539 | that was not enough reason to force linking to gmp and possible |
| 2540 | complications caused by it. |
| 2541 | |
| 2542 | 2013-03-10 Paulo Andrade <pcpa@gnu.org> |
| 2543 | |
| 2544 | * include/lightning.h: Add check for __powerpc__ defined |
| 2545 | in Linux, while Darwin defines __ppc__. |
| 2546 | |
| 2547 | * include/lightning/jit_ppc.h: Adjust register definitions |
| 2548 | for Darwin 32 bit and Linux 64 bit ppc usage and/or ABI. |
| 2549 | |
| 2550 | * include/lightning/jit_private.h: Add proper check for |
| 2551 | Linux __powerpc__ and an data definition for an workaround |
| 2552 | to properly handle code that starts with a jump to a "main" |
| 2553 | label. |
| 2554 | |
| 2555 | * lib/jit_disasm.c: Add extra disassembler initialization |
| 2556 | for __powerpc64__. |
| 2557 | |
| 2558 | * lib/jit_ppc-cpu.c: Add extra macros and functions, and |
| 2559 | correct/adapt previous ones to handle powerpc64. |
| 2560 | |
| 2561 | * lib/jit_ppc-fpu.c: Adapt for 64 bit wordsize. Basically |
| 2562 | add conversion from/to int32/int64 and proper handling of |
| 2563 | load/store offsets too large for 32 bit. |
| 2564 | |
| 2565 | * lib/jit_ppc.c: Add calls to 64 bit codes and adaptation |
| 2566 | for the PowerPC 64 bit Linux ABI. |
| 2567 | |
| 2568 | * lib/jit_arm.c, lib/jit_mips.c, lib/jit_sparc, lib/jit_x86.c, |
| 2569 | lib/lightning.c: Correct off by one error when restarting jit |
| 2570 | of a function due to finding too late that needs to spill/reload |
| 2571 | some register. Problem was found by accident on a very special |
| 2572 | condition during PowerPC 64 code adaptation. |
| 2573 | |
| 2574 | 2013-03-08 Paulo Andrade <pcpa@gnu.org> |
| 2575 | |
| 2576 | * check/lightning.c: Add missing ppc preprocessor definition. |
| 2577 | |
| 2578 | 2013-03-06 Paulo Andrade <pcpa@gnu.org> |
| 2579 | |
| 2580 | * check/float.tst: Comment out the int to negative infinity |
| 2581 | test in mips for the moment because not all Loongson agrees |
| 2582 | on the result. |
| 2583 | |
| 2584 | * lib/jit_disasm.c: Add a test instead of an assertion |
| 2585 | when loading symbols for disassembly due to a failure with |
| 2586 | a simple binutils build in Debian mipsel64. |
| 2587 | |
| 2588 | 2013-03-06 Paulo Andrade <pcpa@gnu.org> |
| 2589 | |
| 2590 | * include/lightning/jit_private.h, lib/jit_arm-cpu.c, |
| 2591 | lib/jit_arm.c, lib/jit_disasm.c, lib/jit_mips-cpu.c, |
| 2592 | lib/jit_mips.c, lib/jit_note.c, lib/jit_ppc-cpu.c, |

| 2594 | lib/jit_sparc.c, lib/jit_x86-cpu.c, lib/jit_x86.c, |
| 2595 | lib/lightning.c: Add an extra structure for data storage |
| 2596 | during jit generation, and release it after generating |
| 2597 | jit, to reduce a bit memory usage, and also to make it |
| 2598 | easier to understand what data is available during |
| 2599 | jit runtime. |
| 2600 | |
| 2601 | 2013-03-06 Paulo Andrade <pcpa@gnu.org> |
| 2602 | |
| 2603 | * lib/lightning.c: Make data and code buffer readonly. |
| 2604 | |
| 2605 | 2013-02-20 Paulo Andrade <pcpa@gnu.org> |
| 2606 | |
| 2607 | * doc/body.texi: Fool proof validate the examples of what |
| 2608 | an assembly-language programmer would write and correct the |
| 2609 | wrong sparc example. |
| 2610 | |
| 2611 | 2013-02-19 Paulo Andrade <pcpa@gnu.org> |
| 2612 | |
| 2613 | * doc/body.texi: Add back the SPARC code generation example. |
| 2614 | |
| 2615 | 2013-02-19 Paulo Andrade <pcpa@gnu.org> |
| 2616 | |
| 2617 | * check/lightning.c: Remove state flag to work with partial |
| 2618 | sparc port, by just disassembling if there was incomplete |
| 2619 | code generation. |
| 2620 | |
| 2621 | * jit_sparc-cpu.c: Correct wrong range check for immediate |
| 2622 | integer constants (off by one bit shift). |
| 2623 | Correct macro implementing equivalent "rd %y, rd" assembly. |
| 2624 | Implement qmul* and qdiv*. |
| 2625 | |
| 2626 | * jit_sparc.c: Update for qmul* and qdiv* and remove logic |
| 2627 | to handle incomplete code generation during sparc port. |
| 2628 | |
| 2629 | 2013-02-18 Paulo Andrade <pcpa@gnu.org> |
| 2630 | |
| 2631 | * check/float.tst: Add sparc to list of known NaN and +-Inf |
| 2632 | to integer conversion. |
| 2633 | |
| 2634 | * check/lightning.c: Define __sparc__ to preprocessor in |
| 2635 | the sparc backend. |
| 2636 | |
| 2637 | * include/lightning/jit_private.h: Correct wrong definition |
| 2638 | of emit_stxi_d, that has lived for a long time, but would |
| 2639 | cause problems whenever needing to spill/reload a float |
| 2640 | register. |
| 2641 | |
| 2642 | * include/lightning/jit_sparc.h: Can only use %g2,%g3,%g4 |
| 2643 | for scratch variables, as other "global" registers are |
| 2644 | reserved for the system, e.g. libc. |
| 2645 | Reorder float register naming to make it easier to |
| 2646 | access odd float registers, so that generating code for |
| 2647 | pusharg and getarg is easier for the IR. |
| 2648 | |
| 2649 | * lib/jit_mips-cpu.c, lib/jit_ppc-cpu.c: Update to match |
| 2650 | new code in jit_sparc-cpu.c. It must call jit_get_reg |
| 2651 | with jit_class_nospill if using the register to move |
| 2652 | an unconditional branch address to it, as the reload |
| 2653 | will not happen (actually could happen in the delay |
| 2654 | slot...) |
| 2655 | |
| 2656 | * lib/jit_sparc-cpu.c: Correct wrong macro definition for |
| 2657 | ldxr_s. |
| 2658 | Properly implement div* and implement rem. Div* needs |
| 2659 | to use the y register, and rem* needs to be synthesized. |
| 2660 | Correct b?sub* macro definitions. |
| 2661 | |
| 2662 | * lib/jit_sparc-fpu.c: Correct reversed float to/from double |
| 2663 | conversion. |
| 2664 | Correct wrong jit_get_reg call asking for a gpr and then |
| 2665 | using the fpr with that number. |
| 2666 | Correct wrong branch displacement computation for |
| 2667 | conditional branches. |
| 2668 | |
| 2669 | * lib/jit_sparc.c: Correct getarg_d and pushargi_d implementation. |
| 2670 | Add rem* entries to the switch converting IR to machine code. |
| 2671 | |
| 2672 | * lib/lightning.c: Correct a problem detected when adding |
| 2673 | the jit_class_nospill flag to jit_get_reg, that was caused |
| 2674 | when having a branch to an "epilog" node, what would cause |
| 2675 | the code to think all registers in unknown state were live, |
| 2676 | while in truth, all registers in unknown state in the |
| 2677 | "just after return" point are actually dead. |
| 2678 | |
| 2679 | 2013-02-17 Paulo Andrade <pcpa@gnu.org> |
| 2680 | |
| 2681 | * include/lightning/jit_sparc.h, lib/jit_sparc-cpu.c, |
| 2682 | lib/jit_sparc-fpu.c, lib/jit_sparc.c: New files implementing |
| 2683 | the basic framework of the sparc port. |
| 2684 | |
| 2685 | * configure.ac, include/lightning.h, include/lightning/Makefile.am, |
| 2686 | include/lightning/jit_private.h, lib/jit_disasm.c: Update |
| 2687 | for the sparc port framework. |
| 2688 | |
| 2689 | * lib/jit_mips.c: Correct reversed retr/reti logic. |
| 2690 | |
| 2691 | * lib/jit_ppc.c: Correct misspelled __LITTLE_ENDIAN. |
| 2692 | |
| 2693 | * lib/lightning.c: Always do byte hashing in hash_data, because |
| 2694 | the logic to "compress" strings causes large pointers to not |
| 2695 | be guaranteed aligned at 4 byte boundaries. |
| 2696 | Update for the sparc port framework. |
| 2697 | |
| 2698 | 2013-02-11 Paulo Andrade <pcpa@gnu.org> |
| 2699 | |
| 2700 | * lib/jit_arm.c: Correct jit_pushargi_f in the arm hardfp abi. |
| 2701 | Most of the logic uses even numbered register numbers, so that |
| 2702 | a float and a double can be used in the same register, but |
| 2703 | the abi requires packing the float arguments, so jit_pushargi_f |
| 2704 | needs to allocate a temporary register to modify only the |
| 2705 | proper register argument (or be very smart to push two |
| 2706 | immediate arguments if applicable). |
| 2707 | |
| 2708 | 2013-02-11 Paulo Andrade <pcpa@gnu.org> |
| 2709 | |
| 2710 | * include/lightning.h, lib/lightning.c: Implement the new |
| 2711 | jit_clear_state and jit_destroy_state calls. jit_clear_state |
| 2712 | releases all memory not required during jit_execution; that |
| 2713 | is, leaves only the mmap'ed data and code buffers allocated. |
| 2714 | jit_destroy_state releases the mmap'ed buffers as well as |
| 2715 | the jit_state_t object itself, that holds pointers to the |
| 2716 | code and data buffers, as well as annotation pointers (for |
| 2717 | disassembly or backtrace) in the data buffer. |
| 2718 | |
| 2719 | * lib/jit_note.c: Correct invalid vector offset access. |
| 2720 | |
| 2721 | * check/ccall.c, check/lightning.c, doc/ifib.c, doc/incr.c, |
| 2722 | doc/printf.c, doc/rfib.c, doc/rpn.c: Use the new jit_clear_state |
| 2723 | and jit_destroy_state calls, to demonstrate the new code to |
| 2724 | release all jit memory. |
| 2725 | |
| 2726 | * doc/body.texi: Add basic documentation and usage description |
| 2727 | of jit_clear_state and jit_destroy_state. |
| 2728 | |
| 2729 | 2013-02-11 Paulo Andrade <pcpa@gnu.org> |
| 2730 | |
| 2731 | * include/lightning/jit_private.h, lib/jit_note.c, lib/lightning.c: |
| 2732 | Store all annotation information in the mmap'ed area reserved for |
| 2733 | read only data. This adds code to not allocate memory for jit_note_t |
| 2734 | objects, and to relocate jit_line_t objects and its contents after |
| 2735 | calculating annotation information. The jit_line_t objects are |
| 2736 | relocated because it is not possible to always calculate before |
| 2737 | hand data layout because note information may be extended or |
| 2738 | redundant entries removed, as well as allowed to be added in |
| 2739 | non sequential order. |
| 2740 | A bug was also corrected in _jit_set_note, that was causing it |
| 2741 | to allocate new jit_line_t objects when not needed. It was still |
| 2742 | working correctly, but allocating way more memory than required. |
| 2743 | |
| 2744 | 2013-02-05 Paulo Andrade <pcpa@gnu.org> |
| 2745 | |
| 2746 | *include/lightning.h, lib/lightning.c: Add the new jit_live code |
| 2747 | to explicitly mark a register as live. It is required to avoid |
| 2748 | assuming functions always return a value in the gpr and fpr return |
| 2749 | register, and to avoid the need of some very specialized codes |
| 2750 | that vary too much from backend to backend, to instruct the |
| 2751 | optimization code the return register is live. |
| 2752 | |
| 2753 | * lib/jit_arm.c, lib/jit_mips.c, lib/jit_ppc.c, lib/jit_print.c, |
| 2754 | lib/jit_x86.c: Update for the new jit_live code. |
| 2755 | |
| 2756 | * check/ret.ok, check/ret.tst: New files implementing a simple |
| 2757 | test case that would previously fail at least in ix86/x86_64. |
| 2758 | |
| 2759 | * check/Makefile.am: Update for new "ret" test case. |
| 2760 | |
| 2761 | 2013-02-05 Paulo Andrade <pcpa@gnu.org> |
| 2762 | |
| 2763 | * lib/jit_ppc-cpu.c, lib/jit_ppc.c: Validate and correct |
| 2764 | problems in the qmul and qdiv ppc implementation. |
| 2765 | |
| 2766 | 2013-02-04 Paulo Andrade <pcpa@gnu.org> |
| 2767 | |
| 2768 | * include/lightning.h, include/lightning/jit_private.h, |
| 2769 | lib/jit_arm-cpu.c, lib/jit_arm.c, lib/jit_mips-cpu.c, |
| 2770 | lib/jit_mips.c, lib/jit_ppc-cpu.c, lib/jit_ppc.c, |
| 2771 | lib/jit_x86-cpu.c, lib/jit_x86.c, lib/lightning.c: |
| 2772 | Implement the new qmul and qdiv instructions that return signed |
| 2773 | and unsigned lo/hi multiplication result and div/rem division result. |
| 2774 | These should be useful for jit translation of code that needs to |
| 2775 | know if a multiplication overflows (no branch opcode added) or if |
| 2776 | a division is exact (easy check if remainder is zero). |
| 2777 | |
| 2778 | * check/lightning.c, lib/jit_print.c, check/Makefile.am, |
| 2779 | check/all.tst: Update for the new qmul and qdiv instructions. |
| 2780 | |
| 2781 | * check/qalu.inc, check/qalu_div.ok, check/qalu_div.tst, |
| 2782 | check/qalu_mul.ok, check/qalu_mul.tst: New files implementing |
| 2783 | simple test cases for qmul and qdiv. |
| 2784 | |
| 2785 | 2013-01-30 Paulo Andrade <pcpa@gnu.org> |
| 2786 | |
| 2787 | * doc/body.texi: Correct "jmpi" description that incorrectly |
| 2788 | told it was possible to pass any address as jump target. The |
| 2789 | only way to do that is "movi+jmpr". |
| 2790 | |
| 2791 | 2013-01-30 Paulo Andrade <pcpa@gnu.org> |
| 2792 | |
| 2793 | * lib/jit_x86-cpu.c: Correct undefined behavior code. |
| 2794 | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56143 |
| 2795 | |
| 2796 | 2013-01-29 Paulo Andrade <pcpa@gnu.org> |
| 2797 | |
| 2798 | * configure.ac: Use AC_CONFIG_HEADERS instead of AC_CONFIG_HEADER |
| 2799 | to have HAVE_CONFIG_H defined with latest aclocal. |
| 2800 | |
| 2801 | * include/lightning/jit_private.h, lib/lightning.c: Add new |
| 2802 | abstraction to use an heuristic to calculate amount of space |
| 2803 | required for jit generation, and code to reallocate buffer if |
| 2804 | did miscalculate it. |
| 2805 | |
| 2806 | * lib/jit_arm.c, lib/jit_mips.c, lib/jit_ppc.c, lib/jit_x86.c: |
| 2807 | Update to use new code to estimate and resize of required buffer |
| 2808 | for jit code. |
| 2809 | |
| 2810 | * lib/jit_x86-cpu.c: Minor cosmetic change to avoid adding a |
| 2811 | non required rex prefix when calling a function pointer stored |
| 2812 | in a register. |
| 2813 | |
| 2814 | 2013-01-24 Paulo Andrade <pcpa@gnu.org> |
| 2815 | |
| 2816 | * check/Makefile.am: "make debug" target should pass only |
| 2817 | the main test tool program as argument for running gdb |
| 2818 | |
| 2819 | * configure.ac: Add the --enable-assertions options. |
| 2820 | |
| 2821 | * doc/Makefile.am, doc/body.texi, doc/lightning.texi: |
| 2822 | Major rewrite of the documentation to match the current |
| 2823 | implementation. |
| 2824 | |
| 2825 | * doc/version.texi: Automatic date update. |
| 2826 | |
| 2827 | * doc/ifib.c, doc/incr.c, doc/printf.c, doc/rfib.c, doc/rpn.c: |
| 2828 | Implementation of the documentation examples, that are also |
| 2829 | compiled during a normal build. |
| 2830 | |
| 2831 | * doc/p-lightning.texi, doc/porting.texi, doc/toc.texi, |
| 2832 | doc/u-lightning.texi, doc/using.texi: These files were |
| 2833 | renamed in the documentation rewrite, as the documentation |
| 2834 | was significantly trimmed due to full removal of the porting |
| 2835 | chapters. Better porting documentation should be added but |
| 2836 | for the moment it was just removed the documentation not |
| 2837 | matching the implementation. |
| 2838 | |
| 2839 | 2013-01-18 Paulo Andrade <pcpa@gnu.org> |
| 2840 | |
| 2841 | * lib/jit_note.c: Correct bounds check and wrong code keeping |
| 2842 | a pointer that could be changed after a realloc call. |
| 2843 | |
| 2844 | 2013-01-18 Paulo Andrade <pcpa@gnu.org> |
| 2845 | |
| 2846 | * check/3to2.tst, check/add.tst, check/allocai.tst, check/bp.tst, |
| 2847 | check/call.tst, check/ccall.c, check/clobber.tst, check/divi.tst, |
| 2848 | check/fib.tst, check/ldsti.tst, check/ldstr-c.tst, check/ldstr.tst, |
| 2849 | check/ldstxi-c.tst, check/ldstxi.tst, check/ldstxr-c.tst, |

| 2854 | lib/jit_x86.c, lib/lightning.c: Extend the "jit_note" abstraction |
| 2855 | with the new "jit_name" call, that receives a string argument, and |
| 2856 | should usually be called to mark boundaries of functions of code |
| 2857 | generating jit (that is, it is not expected that the language |
| 2858 | generating jit map its functions to jit functions). |
| 2859 | |
| 2860 | 2013-01-17 Paulo Andrade <pcpa@gnu.org> |
| 2861 | |
| 2862 | * check/add.tst, check/allocai.tst, check/bp.tst, check/divi.tst, |
| 2863 | check/fib.tst, check/lightning.c, include/lightning/jit_arm.h, |
| 2864 | include/lightning/jit_mips.h, include/lightning/jit_ppc.h, |
| 2865 | include/lightning/jit_private.h, include/lightning/jit_x86.h: |
| 2866 | Make JIT_RET, JIT_FRET and JIT_SP private. These should not be |
| 2867 | used in any operations due to frequently having special |
| 2868 | constraints (usually JIT_FRET). JIT_FP must be made available |
| 2869 | because it must be used as the base register to access stack |
| 2870 | space allocated with jit_allocai. |
| 2871 | |
| 2872 | 2013-01-14 Paulo Andrade <pcpa@gnu.org> |
| 2873 | |
| 2874 | * include/lightning.h, lib/lightning.c: Add an extra align |
| 2875 | argument to the jit_data call (that should be made private), |
| 2876 | so that it should not align strings at 8 bytes. |
| 2877 | Correct the jit_note call to include the null ending byte |
| 2878 | when adding label/note names to the "jit data section". |
| 2879 | |
| 2880 | 2013-01-11 Paulo Andrade <pcpa@gnu.org> |
| 2881 | |
| 2882 | * lib/jit_note.c: New file implementing a simple string+integer |
| 2883 | annotation, that should be used to map filename and line number |
| 2884 | to offsets in the generated jit. |
| 2885 | |
| 2886 | * include/lightning.h, lib/lightning.c: Update for the new |
| 2887 | note code. |
| 2888 | Add an extra mandatory argument to init_jit, that is used |
| 2889 | as argument to bfd_openr. |
| 2890 | Change from generic void* to char* the argument to jit_note |
| 2891 | and add an extra integer argument, to map to filename and |
| 2892 | line number. |
| 2893 | |
| 2894 | * check/ccall.c, check/lightning.c, include/lightning/jit_private.h, |
| 2895 | lib/jit_arm.c, lib/jit_disasm.c, lib/jit_mips.c, lib/jit_ppc.c, |
| 2896 | lib/jit_print.c, lib/jit_x86.c: lib/Makefile.am: Update for the |
| 2897 | new annotation code. |
| 2898 | |
| 2899 | * configure.ac, check/Makefile.am: Update to work with latest |
| 2900 | automake. |
| 2901 | |
| 2902 | 2013-01-09 Paulo Andrade <pcpa@gnu.org> |
| 2903 | |
| 2904 | * include/lightning.h, lib/jit_arm.c, jit_mips-fpu.c, |
| 2905 | lib/jit_mips.c, lib/jit_print.c, lib/jit_x86.c, lib/lightning.c: |
| 2906 | Remove the jit_code_getarg_{f,d} and jit_code_pusharg{i,r}_{f,d} |
| 2907 | calls, replacing them with the new, internal only, jit_movr_w_f, |
| 2908 | jit_mov{r,i}_f_w, jit_movr_ww_d, and jit_mov{i,r}_d_ww, that |
| 2909 | better describe the operation being done, and allow removing |
| 2910 | the hackish code to detect special conditions for arm when |
| 2911 | moving from/to vfp from/to a grp register pair. |
| 2912 | Rename jit_code_retval_{f,d} to jit_code_x86_retval_{f,d} as |
| 2913 | it is specific to 32 bit x86, and used to move abi return |
| 2914 | value in x87 register to a sse register. |
| 2915 | |
| 2916 | 2013-01-05 Paulo Andrade <pcpa@gnu.org> |
| 2917 | |
| 2918 | * check/cccall.c, check/ccall.ok: New test case to validate |
| 2919 | interleaved calls from/to C code and jit. |
| 2920 | |
| 2921 | * check/Makefile.am: Update for the new ccall test case. |
| 2922 | |
| 2923 | * include/lightning.h, lib/lightning.c: Add the new jit_address |
| 2924 | call that returns the real/final address of a "note" in the |
| 2925 | generated jit. It requires a jit_node_t as returned by the |
| 2926 | jit_note call, and is only valid after calling jit_emit. |
| 2927 | Add an intermediate solution to properly handle arm |
| 2928 | soft and softfp modes that move a double to an integer register |
| 2929 | pair. Currently it just adds extra tests for the condition, |
| 2930 | but the proper solution should be to have extra lightning |
| 2931 | codes for these conditions, codes which should be only used |
| 2932 | by the backends that need it, and merged with the existing |
| 2933 | jit_pusharg*_{f,d}. |
| 2934 | |
| 2935 | * include/lightning/jit_private.h: Add new jit_state_t flag |
| 2936 | to know it finished jit_emit, so that calls to jit_address |
| 2937 | are valid. |
| 2938 | |
| 2939 | * lib/jit_mips.c: Correct abi implementation so that the |
| 2940 | new ccall test case pass. Major problem was using |
| 2941 | _jit->function.self.arg{i,f} as boolean values, but that |
| 2942 | would cause lightning.c:patch_registers() to incorrectly |
| 2943 | assume only one register was used as argument when calling |
| 2944 | jit_regarg_p(); _jit->function.self.arg{i,f} must be the |
| 2945 | number of registers used as arguments (in all backends). |
| 2946 | |
| 2947 | * lib/jit_x86.c: Add workaround, by marking %rax as used, |
| 2948 | to a special condition, when running out of registers and the |
| 2949 | allocator trying to spill and reload %rax, but %rax was used |
| 2950 | as a pointer to a function, what would cause the reload to |
| 2951 | destroy the return value. This condition can be better |
| 2952 | generalized, but the current solution is good enough. |
| 2953 | |
| 2954 | * include/lightning/jit_ppc.h, lib/jit_ppc-cpu.c, lib/jit_ppc.c: |
| 2955 | Rewrite logic to handle arguments, as the original code was |
| 2956 | written based on a SysV pdf about the generic powerpc ABI, |
| 2957 | what did "invent" a new abi for the previous test cases, but |
| 2958 | failed in the new ccall test in Darwin PPC. Now it properly |
| 2959 | handles 13 float registers for arguments, as well as proper |
| 2960 | computation of stack offsets when running out of registers |
| 2961 | for arguments. |
| 2962 | |
| 2963 | 2013-01-02 Paulo Andrade <pcpa@gnu.org> |
| 2964 | |
| 2965 | * check/float.tst: Correct test case to match ppc also |
| 2966 | converting positive infinity to 0x7fffffff. |
| 2967 | |
| 2968 | * lib/jit_arm-swf.c: Correct typos with double underscores. |
| 2969 | |
| 2970 | * lib/lightning.c: Correct remaining wrong reverse jump logic. |
| 2971 | |
| 2972 | 2012-12-29 Paulo Andrade <pcpa@gnu.org> |
| 2973 | |
| 2974 | * lib/lightning.c: Correct both, wrong and confusing logic |
| 2975 | to compute the reverse of a jump. Now it properly matches |
| 2976 | C semantics for "eq" (==) and "ne" (!=) and correct computation |
| 2977 | of reverse of "uneq" as "gt". |
| 2978 | |
| 2979 | * check/branch.tst: Update "ne" float branch check that |
| 2980 | previously happened to be wrongly tested with a NaN argument. |
| 2981 | |
| 2982 | 2012-12-29 Paulo Andrade <pcpa@gnu.org> |
| 2983 | |
| 2984 | * check/float.ok, check/float.tst: New test cases implementing |
| 2985 | extensive validation of float comparison and branch code |
| 2986 | generation as well as integer conversion, involving NaN and |
| 2987 | [+-]Inf. |
| 2988 | |
| 2989 | * lib/jit_arm-swf.c, lib/jit_x86-sse.c, lib/jit_x86-x87.c: |
| 2990 | Correct bugs found by new float test case. |
| 2991 | |
| 2992 | * lib/jit_x86.c: Correct cut&paste error added in commit to |
| 2993 | convert jit_arg* return value to a jit_node_t*, that would |
| 2994 | cause it to not properly handle double arguments in ix86. |
| 2995 | |
| 2996 | * check/Makefile.am: Update for the new test case. |
| 2997 | |
| 2998 | 2012-12-28 Paulo Andrade <pcpa@gnu.org> |
| 2999 | |
| 3000 | * check/lightning.c, include/lightning.h, lib/jit_arm.c, |
| 3001 | lib/jit_mips.c, lib/jit_ppc.c, lib/jit_print.c, lib/jit_x86.c, |
| 3002 | lib/lightning.c: Change return value of jit_arg{,_f,_d} to |
| 3003 | a jit_node_t* object, that should be used as argument to |
| 3004 | jit_getarg_{c,uc,s,us,i,ui,l,f,d}. This just requires changing |
| 3005 | from jit_int32_t to jit_pointer_t (or jit_node_t*) the "handle" |
| 3006 | for the getarg calls, with the benefit that it makes it easy |
| 3007 | to implement patching of the stack address of non register |
| 3008 | arguments, this way allowing to implement variable size stack |
| 3009 | frames if applicable; useful if there are too many registers and |
| 3010 | jit functions uses only a few callee save registers. |
| 3011 | |
| 3012 | 2012-12-27 Paulo Andrade <pcpa@gnu.org> |
| 3013 | |
| 3014 | * lib/jit_arm.c, lib/jit_mips-cpu.c, lib/jit_mips.c: Correct |
| 3015 | regressions when patching jit_calli for a forward function. |
| 3016 | |
| 3017 | * lib/jit_ppc-cpu.c: Correct wrong arguments to ANDI opcode |
| 3018 | in jit_getarg_u{c,s} implementation. |
| 3019 | |
| 3020 | 2012-12-23 Paulo Andrade <pcpa@gnu.org> |
| 3021 | |
| 3022 | * check/call.ok, check/call.tst: New test cases to validate |
| 3023 | simple typed argument and return values in function calls. |
| 3024 | |
| 3025 | * check/lightning.c: Properly handle jit_movi of labels for |
| 3026 | backward and forward code labels. |
| 3027 | |
| 3028 | * check/Makefile.am: Update for new test case. |
| 3029 | |
| 3030 | 2012-12-23 Paulo Andrade <pcpa@gnu.org> |
| 3031 | |
| 3032 | * check/carry.ok, check/carry.tst: New test case to validate |
| 3033 | carry condition handling. |
| 3034 | |
| 3035 | * check/Makefile.am: Update for new test case. |
| 3036 | |
| 3037 | 2012-12-22 Paulo Andrade <pcpa@gnu.org> |
| 3038 | |
| 3039 | * lib/jit_ppc-cpu.c, lib/jit_ppc.c: Implement logic for |
| 3040 | jit_htonr for big endian, so that ppc (big endian) pass the |
| 3041 | new clobber.tst test case. |
| 3042 | |
| 3043 | 2012-12-22 Paulo Andrade <pcpa@gnu.org> |
| 3044 | |
| 3045 | * lib/jit_arm.c: Correct use of wrong argument offset |
| 3046 | variable in armv7l or float/double argument for varargs |
| 3047 | function in armv7hl. |
| 3048 | Correct jit_getarg* logic in software float mode to |
| 3049 | match expected behavior in other backends, that is, if |
| 3050 | a function is not called, it is safe to use a few lightning |
| 3051 | calls before a next jit_getarg* call, as done in the test |
| 3052 | case check/stack.tst. The proper solution should be to |
| 3053 | extend the parser in lib/lightning.c to check if there is |
| 3054 | some float operation that will call some (libgcc?) function, |
| 3055 | but software float arm should be a very uncommon backend for |
| 3056 | lightning, so, just load the already in place arguments |
| 3057 | saved to stack, assuming the register argument was clobbered |
| 3058 | (what should not be the case most times...). |
| 3059 | |
| 3060 | 2012-12-22 Paulo Andrade <pcpa@gnu.org> |
| 3061 | |
| 3062 | * check/clobber.ok, check/clobber.tst: New test case doing |
| 3063 | extensive validation tests to ensure registers not used in |
| 3064 | a operation are not clobbered. |
| 3065 | |
| 3066 | * check/Makefile.am: Update for new test case. |
| 3067 | |
| 3068 | 2012-12-21 Paulo Andrade <pcpa@gnu.org> |
| 3069 | |
| 3070 | * lib/lightning.c: Partially rewrite/revert code to compute |
| 3071 | initial register live state at the start of a basic block. |
| 3072 | The original logic was corrupted when adding optimizations |
| 3073 | to do as few computations as possible in jit_update. The |
| 3074 | reglive field must be always a known set of live registers |
| 3075 | at the start of a basic block. The value that was incorrect |
| 3076 | was the regmask field, that must be the set of registers |
| 3077 | that are in unknown state, because they are not known live, |
| 3078 | neither set (or possibly not set) in the basic block, and |
| 3079 | *must* store the state at the start of the basic block. |
| 3080 | |
| 3081 | 2012-12-20 Paulo Andrade <pcpa@gnu.org> |
| 3082 | |
| 3083 | * include/lightning/jit_ppc.h: Correct mismatch of JIT_F{1,5} |
| 3084 | with enum codes, that were correct, and returned by jit_f(). |
| 3085 | |
| 3086 | * lib/jit_ppc-cpu.c, lib/jit_ppc-fpu.c, lib/jit_ppc.c: Properly |
| 3087 | implement and better describe values when generating stack |
| 3088 | frames. |
| 3089 | |
| 3090 | 2012-12-18 Paulo Andrade <pcpa@gnu.org> |
| 3091 | |
| 3092 | * check/stack.ok, check/stack.tst: New files to test data |
| 3093 | integrity on a deep chain of stack frames. |
| 3094 | |
| 3095 | * lib/jit_arm.c, lib/jit_arm-cpu.c, lib/jit_mips.c, |
| 3096 | lib/jit_mips-cpu.c, lib/jit_ppc.c, lib/jit_ppc-cpu.c, |
| 3097 | lib/jit_x86.c, lib/jit_x86-cpu.c: Calculate _jit->function->stack |
| 3098 | in the emit stage, otherwise it will calculate it wrong if |
| 3099 | need to jit_allocai space to spill registers. |
| 3100 | |
| 3101 | * lib/lightning.c: Correct wrong offset when updating the |
| 3102 | "current" jit function pointer in the code that may need to |
| 3103 | allocate stack space to spill registers. |
| 3104 | |
| 3105 | * check/lightning.c: Correct off by one data space check. |
| 3106 | |
| 3107 | * check/Makefile.am: Update for new test case. |
| 3108 | |
| 3109 | 2012-12-17 Paulo Andrade <pcpa@gnu.org> |
| 3110 | |
| 3111 | * check/fop_abs.ok, check/fop_abs.tst, check/fop_sqrt.ok, |
| 3112 | check/fop_sqrt.tst: New files implementing simple test cases |
| 3113 | for the extra float operations. |
| 3114 | |
| 3115 | * check/Makefile.am: Update for new test cases. |
| 3116 | |
| 3117 | * check/alu.inc: Add an extra macro to check for unordered |
| 3118 | equality on tests where it is expected to use NaN as an |
| 3119 | argument. |
| 3120 | |
| 3121 | * check/lightning.c: Minor change for proper/common argument |
| 3122 | syntax handling ommiting arguments to options. |
| 3123 | |
| 3124 | 2012-12-17 Paulo Andrade <pcpa@gnu.org> |
| 3125 | |
| 3126 | * check/Makefile.am: Automatically generate pattern list |
| 3127 | of tests with alternate jit generation options. This should |
| 3128 | prevent typos and needing to change multiple places after |
| 3129 | a change. |
| 3130 | |
| 3131 | 2012-12-14 Paulo Andrade <pcpa@gnu.org> |
| 3132 | |
| 3133 | * check/lightning.c: Remove the ".cpu name value" syntax, |
| 3134 | as it was not able to do proper changes before the jit |
| 3135 | internal data structure was initialized. Now it supports |
| 3136 | several getopt options to force using different jit |
| 3137 | generation options, effectively replacing the previous |
| 3138 | syntax. |
| 3139 | |
| 3140 | * check/run-test: Add simple extra logic to handle differently |
| 3141 | named test scripts, used to test things like x87 coprocessor |
| 3142 | in ix86, and arm instruction set or software float in armv7l. |
| 3143 | |
| 3144 | * configure.ac: Add some AC_RUN_IFELSE calls to figure at |
| 3145 | compile time if can test different code generation options, |
| 3146 | and update Makefile generation accordingly. |
| 3147 | |
| 3148 | * check/Makefile.am, lib/jit_arm.c, lib/jit_x86.c: Update to |
| 3149 | properly work with the test tool updating the jit_cpu global |
| 3150 | information. |
| 3151 | |
| 3152 | * check/check.arm.sh, check/check.swf.sh, check/check.x87.sh: |
| 3153 | New wrapper files passing -mthumb=0, mvfp=0 and -mx87=1 to |
| 3154 | the test tool, if applicable, so that it can validate alternate |
| 3155 | code generation options on test hosts that support them. |
| 3156 | |
| 3157 | 2012-12-14 Paulo Andrade <pcpa@gnu.org> |
| 3158 | |
| 3159 | * lib/jit_x86-x87.c, lib/jit_x86.c: Correct test cases in ix86 |
| 3160 | when using the x87 coprocessor instead of sse2+. |
| 3161 | |
| 3162 | 2012-12-14 Paulo Andrade <pcpa@gnu.org> |
| 3163 | |
| 3164 | * include/lightning.h, include/lightning/jit_private.h, |
| 3165 | lib/jit_arm.c, lib/jit_mips.c, lib/jit_ppc.c, lib/jit_x86.c, |
| 3166 | lib/lightning.c: Make jit_ellipsis implementation not |
| 3167 | backend specific. It is not intended to handle va_list |
| 3168 | like objects at runtime, as jit_arg* and jit_getarg* |
| 3169 | return constant values resolved at parse time, so, effectively |
| 3170 | it is not possible to create printf like jit functions, as |
| 3171 | there is no va_start, va_arg, va_end, etc, abstraction. This |
| 3172 | limitation should be kept for the sake of making new ports |
| 3173 | easier. |
| 3174 | |
| 3175 | 2012-12-14 Paulo Andrade <pcpa@gnu.org> |
| 3176 | |
| 3177 | * include/lightning.h, lib/lightning.c: Add two extra wrapper |
| 3178 | functions to avoid need for excess pointer to/from word casts. |
| 3179 | |
| 3180 | * check/lightning.c: Only need for pointer to/from word cast |
| 3181 | now is jit_movi, update accordingly. |
| 3182 | |
| 3183 | 2012-12-13 Paulo Andrade <pcpa@gnu.org> |
| 3184 | |
| 3185 | * check/varargs.ok, check/varargs.tst: New test cases implementing |
| 3186 | simple varargs calls with a large amount of arguments to exercise |
| 3187 | excess arguments on stack. |
| 3188 | |
| 3189 | * include/lightning.h: Include config.h if HAVE_CONFIG_H is |
| 3190 | defined. |
| 3191 | |
| 3192 | * lib/jit_arm.c: Allocate a fpr register, not a gpr one for |
| 3193 | temporary when pushing varargs arguments in the stack. |
| 3194 | |
| 3195 | * lib/jit_arm-swf.c: Correct code changing the wrong offset |
| 3196 | in jit_absr_d and jit_negr_d in software float. |
| 3197 | |
| 3198 | * lib/jit_mips.c: Correct calculation of offsets of arguments |
| 3199 | on stack. |
| 3200 | |
| 3201 | * lib/jit_ppc.c: Correct bogus logic for "next" offset of arguments |
| 3202 | on stack and adjust for fixed offset of stack arguments. |
| 3203 | |
| 3204 | 2012-12-12 Paulo Andrade <pcpa@gnu.org> |
| 3205 | |
| 3206 | * include/lightning.h, lib/jit_arm.c, lib/jit_mips.c, |
| 3207 | lib/jit_ppc.c, lib/jit_x86.c, lib/lightning.c: Change jit_prepare |
| 3208 | to no longer receive an argument. If receiving an argument, it |
| 3209 | should be an ABI specifier, not a boolean if varargs or not, |
| 3210 | and add the new jit_ellipsis call, to specify where the |
| 3211 | ellipsis is in the C prototype of the function being called. |
| 3212 | Note that currently it is not supported to define varargs |
| 3213 | functions and it will be ignored if calling jit_ellipsis not |
| 3214 | in a prepare/finish* block, but this should be addressed. |
| 3215 | |
| 3216 | * check/allocai.tst, check/alu_add.tst, check/alu_and.tst, |
| 3217 | check/alu_com.tst, check/alu_div.tst, check/alu_lsh.tst, |
| 3218 | check/alu_mul.tst, check/alu_neg.tst, check/alu_or.tst, |
| 3219 | check/alu_rem.tst, check/alu_rsh.tst, check/alu_sub.tst, |
| 3220 | check/alu_xor.tst, check/alux_add.tst, check/alux_sub.tst, |
| 3221 | check/bp.tst, check/branch.tst, check/cvt.tst, check/divi.tst, |
| 3222 | check/fib.tst, check/ldsti.tst, check/ldstr-c.tst, |
| 3223 | check/ldstr.tst, check/ldstxi-c.tst, check/ldstxi.tst, |
| 3224 | check/ldstxr-c.tst, check/ldstxr.tst, check/rpn.tst, |
| 3225 | check/lightning.c: Update for the change to jit_prepare and |
| 3226 | addition of jit_ellipsis. |
| 3227 | |
| 3228 | 2012-12-11 Paulo Andrade <pcpa@gnu.org> |
| 3229 | |
| 3230 | * lib/jit_ppc-cpu.c: Make movr a function that checks arguments |
| 3231 | so that other code can safely assume it is a noop if src and dst |
| 3232 | are the same register. |
| 3233 | Implement rem{r,i}{,_u} as a div{,u}/mul/sub. |
| 3234 | Correct ANDIS, ORIS and XORIS calls to cast the argument to |
| 3235 | unsigned before the shift to avoid an assertion if the argument |
| 3236 | had the topmost bit set. |
| 3237 | Implement lshi, rshi and rshi_u as functions to test for a |
| 3238 | zero argument, that would otherwise trigger an assertion when |
| 3239 | computing the shift value. |
| 3240 | Do a simple implementation of bm{s,c}{r,i} with a temporary, |
| 3241 | "andr" of arguments and jump based on comparison with zero. |
| 3242 | Correct typo in ldxi_c. |
| 3243 | |
| 3244 | * lib/jit_ppc-fpu.c: Correct wrong arguments to FDIV* and STF*. |
| 3245 | |
| 3246 | * lib/jit_ppc.c: Correct wrong check for 6 instead of 8 integer |
| 3247 | arguments in registers. If calling a varargs function and |
| 3248 | passing a float or double argument, also either store the |
| 3249 | value in the stack or in integer registers, as varargs functions |
| 3250 | do not fetch it from float registers. |
| 3251 | Add "case" for new functions and incorrectly missing ones. |
| 3252 | Call libgcc's __clear_cache, that should know what to do |
| 3253 | if the hardware needs flushing cache before execution. |
| 3254 | |
| 3255 | * lib/lightning.c: Do a simple/trivial logic in jit_regset_scan1, |
| 3256 | that should make it easier for the compiler to optimize it, and |
| 3257 | that also corrects the previously wrong code for big endian, and |
| 3258 | that was causing problems in ppc due to not saving all callee save |
| 3259 | registers as it was not "finding" them in the regset due to the |
| 3260 | little endian assumption bug. |
| 3261 | |
| 3262 | 2012-12-11 Paulo Andrade <pcpa@gnu.org> |
| 3263 | |
| 3264 | * configure.ac: Only default to using the builtin disassembler |
| 3265 | if on GNU/Linux. This should be temporary, due to requiring |
| 3266 | /proc/self/exe. |
| 3267 | Correctly check $target_cpu for powerpc. |
| 3268 | |
| 3269 | * include/lightning/jit_ppc.h: Correctly implement jit_v_num. |
| 3270 | |
| 3271 | * include/lightning/jit_private.h: Declare proper prototype |
| 3272 | for jit_init_debug and jit_finish_debug. |
| 3273 | |
| 3274 | * lib/jit_ppc-cpu.c: Remove code to save/restore callee save |
| 3275 | float registers, as it is not required since those float |
| 3276 | registers are not usable currently. |
| 3277 | Change prolog and epilog generation to, at least comparing |
| 3278 | code, match what gcc generates in "gcc -O0", but it is still |
| 3279 | failing in Darwin PPC, apparently due to the __clear_cache |
| 3280 | call not being enough, as frequently it will also fail to |
| 3281 | execute, and the code buffer is all zeroes. |
| 3282 | |
| 3283 | * lib/lightning.c: Do not fail in jit_regset_scan1 calls due |
| 3284 | to passing 64 as argument on computers with 64 registers. |
| 3285 | |
| 3286 | 2012-12-10 Paulo Andrade <pcpa@gnu.org> |
| 3287 | |
| 3288 | * lib/jit_mips-cpu.c: Correct all current test cases. |
| 3289 | Call the "xori" not the "XORI" macro for jit_xori implementation, |
| 3290 | as the XORI macro handles only 16 bit unsigned values. |
| 3291 | Call the "movr" macro, not the "movi" macro in the special |
| 3292 | case of adding or subtracting zero. |
| 3293 | Use the proper temporary register in the jit_andr implementation. |
| 3294 | |
| 3295 | 2012-12-09 Paulo Andrade <pcpa@gnu.org> |
| 3296 | |
| 3297 | * check/alu.inc, check/alu_add.ok, check/alu_add.tst, |
| 3298 | check/alu_and.ok, check/alu_and.tst, check/alu_com.ok, |
| 3299 | check/alu_com.tst, check/alu_div.ok, check/alu_div.tst, |

| 3303 | check/alu_rem.tst, check/alu_rsh.ok, check/alu_rsh.tst, |
| 3304 | check/alu_sub.ok, check/alu_sub.tst, check/alu_xor.ok, |
| 3305 | check/alu_xor.tst, check/alux_add.ok, check/alux_add.tst, |
| 3306 | check/alux_sub.ok, check/alux_sub.tst, check/branch.ok, |
| 3307 | check/branch.tst: New test cases for arithmetic and branch |
| 3308 | tests. |
| 3309 | |
| 3310 | * check/Makefile.am: Update for new test cases. |
| 3311 | |
| 3312 | * include/lightning/jit_private.h: Make the jit_reg_free_p |
| 3313 | macro shared by all backends. Previously was added for the |
| 3314 | arm backend, but is useful in the x86_64 backend when checking |
| 3315 | state of "special purpose register". |
| 3316 | Also add the new jit_class_named register class, that must be |
| 3317 | or'ed with the register value if calling jit_get_reg expecting |
| 3318 | an specific value, because the specific register value may be |
| 3319 | zero, that previously was treated as no register requested. |
| 3320 | |
| 3321 | * lib/jit_arm-cpu.c: Correct argument order for T2_MVN. |
| 3322 | |
| 3323 | * lib/jit_arm-swf.c: Call the proper function for double |
| 3324 | divide. The "software float" implementation just calls |
| 3325 | libgcc functions. |
| 3326 | |
| 3327 | * lib/jit_arm.c: Return float/double values in the float |
| 3328 | register if using the hard float ABI. |
| 3329 | |
| 3330 | * lib/jit_x86-cpu.c: Change the can_sign_extend_int_p macro |
| 3331 | to not include -0x80000000L, because there is code that |
| 3332 | "abuses" it and thinks it can negate the immediate value |
| 3333 | after calling that macro. |
| 3334 | Correct implementation of jit_subi that had a wrong code |
| 3335 | patch logic doing subtraction with reversed arguments. |
| 3336 | Correct REX prefix calculation in the jit_muli implementation. |
| 3337 | Correct logic to get/unget %*ax and %*dx registers in divremr |
| 3338 | and divremi. |
| 3339 | Correct divremi that was using the symbolic, unique %*ax |
| 3340 | value in on place (not using the _REGNO name suffix). |
| 3341 | Correct cut&paste error causing it to use "xor" instead of |
| 3342 | "or" in one code path of the jit_ori implementation. |
| 3343 | Correct several flaws when clobbering registers and/or when |
| 3344 | one of the arguments was %*cx in the rotshr wrapper function |
| 3345 | implementing most shift operations. |
| 3346 | |
| 3347 | * lib/lightning.c: No longer expect that the backend be smart |
| 3348 | enough to know what to do when asking for a named register |
| 3349 | if that register is already an argument or is live. It fails |
| 3350 | if it is an argument, or if register is live, fails if cannot |
| 3351 | spill. |
| 3352 | No longer incorrectly assume that eqr_{f,d} and ltgr_{f,d} are |
| 3353 | safe to inverse value tests in jump thread optimization. |
| 3354 | |
| 3355 | 2012-12-05 Paulo Andrade <pcpa@gnu.org> |
| 3356 | |
| 3357 | * check/Makefile.am, check/cvt.ok, check/cvt.tst: Add new |
| 3358 | "cvt" test case to test conversion from/to int/float types. |
| 3359 | |
| 3360 | * check/lightning.c: Only define truncr_{f,d}_l in 64 bit mode. |
| 3361 | |
| 3362 | * include/lightning.h: Correct typo that caused it to define |
| 3363 | jit_truncr_{f,d}_l in 32 bit mode. |
| 3364 | |
| 3365 | * lib/jit_arm-cpu.c: Avoid assertion failure in the signed/unsigned |
| 3366 | extend opcodes generation as it shares an interface for 3 argument |
| 3367 | opcode generation. |
| 3368 | |
| 3369 | * lib/jit_x86-cpu.c: Correct wrong argument passed to |
| 3370 | jit_unget_reg in the andi implementation and wrong byte |
| 3371 | unsigned extend code generation. |
| 3372 | |
| 3373 | * lib/jit_x86-sse.c: Correct conversion from "word" to float or |
| 3374 | double as is dependent on wordsize. |
| 3375 | |
| 3376 | 2012-12-05 Paulo Andrade <pcpa@gnu.org> |
| 3377 | |
| 3378 | * check/ldstr-c.ok, check/ldstr-c.tst, check/ldstxi-c.ok, |
| 3379 | check/ldstxi-c.tst, check/ldstxr-c.ok, check/ldstxr-c.tst: |
| 3380 | New test case files testing load clobbering the base and/or |
| 3381 | index register; |
| 3382 | |
| 3383 | * check/ldst.inc: New file with common definition for all the |
| 3384 | ldst* test cases. |
| 3385 | |
| 3386 | check/Makefile.am, check/ldsti.tst, check/ldstr.tst, |
| 3387 | check/ldstxi.tst, check/ldstxr.tst: Update for new common |
| 3388 | definitions file and new register clobber ldst tests. |
| 3389 | |
| 3390 | 2012-12-05 Paulo Andrade <pcpa@gnu.org> |
| 3391 | |
| 3392 | * lib/jit_mips-fpu.c: Correct wrong register order in stxr_{f,d} |
| 3393 | in the mips backend. |
| 3394 | |
| 3395 | 2012-12-05 Paulo Andrade <pcpa@gnu.org> |
| 3396 | |
| 3397 | * lib/jit_arm-vfp.c: Correct regression found in armv7l with |
| 3398 | latest test cases. |
| 3399 | |
| 3400 | 2012-12-05 Paulo Andrade <pcpa@gnu.org> |
| 3401 | |
| 3402 | * check/ldstxi.tst, check/ldstxr.tst: Correct wrong argument |
| 3403 | order for 32 bit mode tests. |
| 3404 | |
| 3405 | * configure.ac: Correct check for ix86 target_cpu. |
| 3406 | |
| 3407 | 2012-12-05 Paulo Andrade <pcpa@gnu.org> |
| 3408 | |
| 3409 | * check/ldstr.ok, check/ldstr.tst, check/ldsti.ok, |
| 3410 | check/ldsti.tst, check/ldstxr.ok, check/ldstxr.tst, |
| 3411 | check/ldstxi.ok, check/ldstxi.tst: |
| 3412 | New test case files exercising a very large amount of |
| 3413 | register combinations to verify load/store implementation. |
| 3414 | |
| 3415 | * check/Makefile.am: Update for new test cases. |
| 3416 | |
| 3417 | * lib/jit_x86-cpu.c: Correct wrong argument order when |
| 3418 | computing REX prefix for {ld,st}r_T codes; |
| 3419 | |
| 3420 | 2012-12-04 Paulo Andrade <pcpa@gnu.org> |
| 3421 | |
| 3422 | * lib/jit_mips-fpu.c, lib/jit_mips.c: Implement missing mips |
| 3423 | jit_sqrtr_{f,d} codes. |
| 3424 | |
| 3425 | * check/all.tst, include/lightning.h, lib/jit_print.c: Change |
| 3426 | declaration order and call order in all.tst of {add,sub}c and |
| 3427 | {add,sub}x. *c must be called before to set the carry and *x |
| 3428 | second to use the carry and keep it set. The wrong call order |
| 3429 | was causing all.tst to fail in mips, where a register is |
| 3430 | allocated to keep a global carry state. |
| 3431 | |
| 3432 | 2012-12-04 Paulo Andrade <pcpa@gnu.org> |
| 3433 | |
| 3434 | * include/lightning/jit_mips.h, lib/jit_mips-cpu.c, |
| 3435 | lib/jit_mips-fpu.c, lib/jit_mips.c: Correct float/double |
| 3436 | argument handling and make the mips backend pass the initial |
| 3437 | test cases. |
| 3438 | |
| 3439 | * include/lightning.h, ib/jit_print.c, lib/lightning.c: |
| 3440 | Add extra enum values for argument handling functions that |
| 3441 | could not be abstracted to the current codes, that is, when |
| 3442 | float values need to move from/to gpr from/to fpr. It would |
| 3443 | be more tempting to add such primitives, but they would have |
| 3444 | wordsize limitations, and it is not expected to add codes |
| 3445 | with one gpr argument for 64 bit and two for 32 bit. |
| 3446 | |
| 3447 | * lib/jit_ppc.c: Check _jit->function before calling jit_epilog() |
| 3448 | to avoid a runtime exception. |
| 3449 | |
| 3450 | 2012-12-04 Paulo Andrade <pcpa@gnu.org> |
| 3451 | |
| 3452 | * include/lightning/jit_mips.h, lib/jit_mips.c: Update to |
| 3453 | make the mips backend compile in a qemu image. |
| 3454 | |
| 3455 | * lib/jit_ppc.c: Minor adaptations to help in having the |
| 3456 | ppc backend compilable. |
| 3457 | |
| 3458 | 2012-12-03 Paulo Andrade <pcpa@gnu.org> |
| 3459 | |
| 3460 | * configure.ac, include/lightning/jit_private.h, lib/jit_arm-cpu.c, |
| 3461 | lib/jit_arm-swf.c, lib/jit_arm.c, check/Makefile.am: Correct |
| 3462 | implementation of the arm backend port to build and pass the |
| 3463 | current test cases. Tested on armv7 with softfp abi. |
| 3464 | |
| 3465 | * lib/jit_disasm.c: Rename and change prototype of static |
| 3466 | disassemble function as in the arm backend it is required |
| 3467 | to access state information stored in the jit_state_t object. |
| 3468 | |
| 3469 | * check/3to2.tst, check/add.tst: Correct test case code assuming |
| 3470 | JIT_RO and JIT_RET are the same, and even if they are the same, |
| 3471 | the logic was incorrect because it must always call jit_retval* |
| 3472 | to fetch a function call return before any other instruction. |
| 3473 | The arm backend hash a special condition if jit_retval is not |
| 3474 | called, because "r0" is not JIT_R0, but is JIT_RET and *also* |
| 3475 | the first argument for a called function, so JIT_RET must be |
| 3476 | only used as an argument to jit_retval. |
| 3477 | |
| 3478 | 2012-12-03 Paulo Andrade <pcpa@gnu.org> |
| 3479 | |
| 3480 | * check/all.tst, check/lightning.c: Only declare or use 64 bit |
| 3481 | interfaces on 64 bit builds. |
| 3482 | |
| 3483 | * check/fib.tst: Use simpler logic to not need preprocessor |
| 3484 | conditionals for 32 or 64 bit. |
| 3485 | |
| 3486 | * include/lightning.h: Only declare 64 bit macros on a 64 bit |
| 3487 | build. Code using lightning must know about wordsize and the |
| 3488 | jit generation limitations, also, this way it generates a |
| 3489 | compile time failure, not a runtime assertion. |
| 3490 | |
| 3491 | * include/lightning/jit_x86.h: Correct typo in macro name. |
| 3492 | |
| 3493 | * lib/jit_arm.c, lib/jit_arm-cpu.c, lib/jit_mips.c, |
| 3494 | lib/jit_mips-cpu.c, lib/jit_ppc.c, lib/jit_ppc-cpu.c, |
| 3495 | lib/jit_x86.c, lib/jit_x86-cpu.c: Correct wrong code to get |
| 3496 | current jit function pointer. |
| 3497 | |
| 3498 | * lib/lightning.c: Move call to the simplify() optimization |
| 3499 | to after register liveness is known. Previous code did work |
| 3500 | by accident but now with proper test cases the problem was |
| 3501 | noticed. |
| 3502 | |
| 3503 | * lib/jit_disasm.c: Always cast bfd_vma to long long when |
| 3504 | passing it as printf argument. |
| 3505 | |
| 3506 | 2012-12-03 Paulo Andrade <pcpa@gnu.org> |
| 3507 | |
| 3508 | * configure.ac, check/Makefile.am, check/check.sh, |
| 3509 | doc/Makefile.am, include/lightning/Makefile.am, |
| 3510 | lib/Makefile.am: Correct make distcheck. |
| 3511 | |
| 3512 | 2012-12-02 Paulo Andrade <pcpa@gnu.org> |
| 3513 | |
| 3514 | * lib/jit_ppc.c: Assign copyright ownership to FSF. |
| 3515 | |
| 3516 | * lib/jit_x86-cpu.c: Correct integer multiplication that was |
| 3517 | generating code with reversed register arguments. |
| 3518 | |
| 3519 | * check/rpn.ok, check/rpn.tst: New test case file. |
| 3520 | |
| 3521 | 2012-12-02 Paulo Andrade <pcpa@gnu.org> |
| 3522 | |
| 3523 | * lib/jit_x86-cpu.c, lib/jit_x86-sse.c, lib/jit_x86-x87.c: |
| 3524 | Actually change copyright owner to FSF as avertised. |
| 3525 | |
| 3526 | * lib/jit_arm-cpu.c, lib/jit_arm-swf.c, |
| 3527 | lib/jit_arm-vfp.c, lib/jit_arm.c, |
| 3528 | lib/jit_mips-cpu.c, lib/jit_mips-fpu.c, lib/jit_mips.c, |
| 3529 | lib/jit_ppc-cpu.c, lib/jit_ppc-fpu.c, lib/jit_ppc.c: New |
| 3530 | files implementing initial code different jit backends. |
| 3531 | |
| 3532 | * include/lightning/jit_private.h: Add extra field to the |
| 3533 | private jit_patch_t type, required by the arm port. |
| 3534 | |
| 3535 | * lib/Makefile.am: Update for the new backend implementation |
| 3536 | files. |
| 3537 | |
| 3538 | 2012-12-02 Paulo Andrade <pcpa@gnu.org> |
| 3539 | |
| 3540 | * check/Makefile.am: Add proper "make clean" rule and missing |
| 3541 | check.sh to EXTRA_DIST. |
| 3542 | |
| 3543 | 2012-12-02 Paulo Andrade <pcpa@gnu.org> |
| 3544 | |
| 3545 | * .gitignore: Update pattern of ignored files. |
| 3546 | |
| 3547 | * check/Makefile.am: Add rule to build liblightning.la dependency |
| 3548 | in case of running "make check" before building the library. |
| 3549 | |
| 3550 | 2012-12-02 Paulo Andrade <pcpa@gnu.org> |
| 3551 | |
| 3552 | * lightning/Makefile.am, lightning/asm-common.h, |

| 3562 | lightning/sparc/asm.h, lightning/sparc/core.h, |
| 3563 | lightning/sparc/fp.h, lightning/sparc/funcs.h: |
| 3564 | Removed. The core logic is used in the new code, and new mips |
| 3565 | and arm ports will be added. At first, sparc will not be |
| 3566 | supported as it has not yet been ported to the new engine. |
| 3567 | |
| 3568 | 2012-12-02 Paulo Andrade <pcpa@gnu.org> |
| 3569 | |
| 3570 | * tests/Makefile.am, tests/3to2.c, tests/3to2.ok, tests/add.c, |

| 3579 | tests/rpnfp.ok, tests/sete.c, tests/sete.ok, tests/testfp.c, |
| 3580 | tests/testfp.ok, tests-run-test: Removed previous test suite, in |
| 3581 | favor of a newer one in the check subdirectory. |
| 3582 | |
| 3583 | * check/3to2.ok, check/3to2.tst, check/add.ok, check/add.tst, |
| 3584 | check/allocai.ok, check/allocai.tst, check/bp.ok, check/bp.tst, |
| 3585 | check/divi.ok, check/divi.tst, check/fib.ok, check/fib.tst: |
| 3586 | New sample input for the new test program, loosely matching |
| 3587 | several of the previous test cases. |
| 3588 | |
| 3589 | * check/Makefile.am: New test suite makefile. |
| 3590 | |
| 3591 | * check/check.sh, check/run-test: New wrapper files for the |
| 3592 | new test suite. |
| 3593 | |
| 3594 | * check/lightning.c: New file. The main driver of the new test |
| 3595 | suite, that compiles to a parser of a very simple assembly like |
| 3596 | language, generates jit and executes it. |
| 3597 | |
| 3598 | * check/all.tst: New file. A generic debug and sample test file |
| 3599 | with a directive to prevent it from being executed, and useful to |
| 3600 | read disassembly of all possible instructions, using a fixed set |
| 3601 | of registers. |
| 3602 | |
| 3603 | * include/Makefile.am, include/lightning.h, |

| 3609 | lib/jit_x86.c, lib/lightning.c: New files. These files are |
| 3610 | written from scratch, only by <pcpa@gnu.org>, and have now |
| 3611 | copyright assignment to the FSF. This is the core of the new |
| 3612 | lightning rework. Previously it was integrated in code with |
| 3613 | a garbage collector and several custom types like vectors and |
| 3614 | hash tables, so this first code merge with lightning converts |
| 3615 | that code into a library extracting only the jit bits, and at |
| 3616 | first only for x86_64 GNU/Linux. |
| 3617 | |
| 3618 | * lightning.h, m4/lightning.m4: Removed. These are no longer |
| 3619 | required in the new lightning code. |
| 3620 | |
| 3621 | .gitignore, Makefile.am, configure.ac: Update for the new |
| 3622 | lightning code. |
| 3623 | |
| 3624 | 2012-12-02 Paulo Andrade <pcpa@gnu.org> |
| 3625 | * .cvsignore: Removed for extra cleanup. |
| 3626 | |
| 3627 | * build-aux: Rename directory to m4. |
| 3628 | |
| 3629 | * m4: Renamed to "default" name and for consistency with merge |
| 3630 | with code rework to be imported in lightning. |
| 3631 | |
| 3632 | * .gitignore, configure.ac, Makefile.am, doc/Makefile.am: |
| 3633 | Update for build-aux to m4 rename. |
| 3634 | |
| 3635 | 2012-12-01 Paulo Andrade <pcpa@gnu.org> |
| 3636 | |

| 3640 | opcode/ppc.h, opcode/sparc-dis.c, opcode/sparc-opc.c, opcode/sparc.h, |
| 3641 | opcode/sysdep.h: Removed. Do not bundle GNU binutils files. |
| 3642 | |
| 3643 | * aclocal.m4, configure, Makefile.in, config.h.in, doc/Makefile.in, |
| 3644 | lightning/Makefile.in, tests/Makefile.in: Removed. Do not maintain |
| 3645 | autogenerated files that also generate too much diff noise when |
| 3646 | regenerated in git. |
| 3647 | |
| 3648 | * build-aux/help2man, build-aux/texinfo.tex, build-aux/texi2dvi: |
| 3649 | Removed. Buildenvironment must have an up to date version from |
| 3650 | upstream installed. |
| 3651 | |
| 3652 | * build-aux/config.guess, build-aux/config.sub, build-aux/depcomp, |
| 3653 | build-aux/install-sh build-aux/mdate-sh build-aux/missing: Removed. |
| 3654 | Do not maintain a copy of automake files in git. Release tarballs |
| 3655 | must use an up to date version. |
| 3656 | |
| 3657 | * lightningize.in, doc/lightningize.1: Removed. Do not encourage |
| 3658 | bundling lightning in other packages. It should use a system package |
| 3659 | or a proper thirdy part subdirectory. |
| 3660 | |
| 3661 | * INSTALL: Removed. Autoreconf removes it and creates a symlink |
| 3662 | when regenerating files, so, avoid conflicts in git and let |
| 3663 | automake create the symlink. |
| 3664 | |
| 3665 | * .gitignore: Add INSTALL and autogenerated files. |
| 3666 | |
| 3667 | * configure.ac, Makefile.am: Update for removal of opcode subdir, |
| 3668 | auto generated files and lightningize. |
| 3669 | |
| 3670 | * tests/Makefile.am, tests/3to2.c, tests/add.c, tests/bp.c, |

| 3672 | tests/incr.c, tests/printf.c, tests/rpn.c, tests/rpnfp.c, |
| 3673 | tests/sete.c, tests/testfp.c: Update for removal of opcode subdir. |
| 3674 | |
| 3675 | * doc/Makefile.am: Update for removal of lightningize. |
| 3676 | |
| 3677 | * configure.ac, lightning/ppc/funcs.h, lightning/sparc/funcs.h, |
| 3678 | lightning/i386/fp.h, lightning/i386/core.h, lightning/i386/asm.h, |

| 3681 | tests/rpn.c, tests/rpnfp.c, tests/sete.c, tests/testfp.c: |
| 3682 | Remove LIGHTNING_CROSS, it is half supported and incomplete. |
| 3683 | |
| 3684 | * tests/3to2.c, tests/funcfp.c, tests/rpnfp.c: Remove preprocessor |
| 3685 | check on JIT_FPR. If no hardware registers are available, the backend |
| 3686 | must provide an alternative for software float. |
| 3687 | |
| 3688 | * lightning/ppc/core.h, lightning/sparc/core.h, tests/Makefile.am: |
| 3689 | Remove JIT_NEED_PUSH_POP. It is absolutely not trivial to implement |
| 3690 | properly on some backends due to stack alignment constraints, and |
| 3691 | whenever it is required, using jit_allocai and using a properly |
| 3692 | aligned stack vector, or a heap buffer, is better. |
| 3693 | |
| 3694 | * tests/push-pop.c, tests/push-pop.ok: Removed due to |
| 3695 | JIT_NEED_PUSH_POP no longer available. |
| 3696 | |
| 3697 | 2011-02-28 Paolo Bonzini <bonzini@gnu.org> |
| 3698 | |
| 3699 | * lightning/i386/core-64.h: Add jit_add{c,x}{i,r}_l, jit_mulr_{l,ul}_, |
| 3700 | fix jit_mul{i,r}_{l,ul}. |
| 3701 | |
| 3702 | 2010-08-20 Paolo Bonzini <bonzini@gnu.org> |
| 3703 | |
| 3704 | * lightning/i386/fp-64.h: Return patch address from jit_bXYr_{f,d}. |
| 3705 | Reported by Paulo César Pereira de Andrade. |
| 3706 | * lightning/ppc/fp.h: Likewise. |
| 3707 | * lightning/sparc/fp.h: Implement FP branches. |
