| | 26 | r0 = r1 * r2 +/- r3. |
| | 27 | * include/lightning/jit_private.h: Add helper macros for debug |
| | 28 | output. |

| | 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 |

| | 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. |

| | 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 |

| | 94 | ext, ext_u and dep. |
| | 95 | * lib/lightning.c: Add code to understand the new instructions |
| | 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. |

| | 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, |

| | 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 |

| | 149 | * lib/jit_x86-cpu.c, lib/jit_x86.c: Implement optimized |
| | 150 | popcntr instruction using the popcnt instruction if available, |
| | 151 | otherwise use an optimized fallback. |
| | 152 | * lib/jit_fallback.c: Implement simple fallback popcnt. |
| | 153 | * lib/jit_hppa.c, lib/jit_loongarch.c, lib/jit_mips.c, |

| | 155 | popcnt. |
| | 156 | |
| | 157 | 2023-02-26 Paulo Andrade <pcpa@gnu.org> |
| | 158 | |

| | 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 |

| | 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. |

| | 206 | lib/jit_ia64.c, lib/jit_loongarch.c, lib/jit_mips.c, lib/jit_ppc.c, |
| | 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 |

| | 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. |

| | 341 | * lib/jit_x86.c: Implement skip instruction. |
| | 342 | * lib/lightning.c: Classify skip instruction. |
| | 343 | |
| | 344 | 2022-10-30 Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de> |
| | 345 | |
| | 346 | Add user-visible functions jit_protect and jit_unprotect. |
| | 347 | * check/Makefile.am: Add test for jit_protect and jit_unprotect. |
| | 348 | * check/protect.c: New test. |

| | 352 | jit_unprotect. |
| | 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, |

| | 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. |

| | 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, |

| | 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> |

| | 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 |
| | 1105 | registers is executed. |
| | 1106 | |
| | 1107 | * check/carg.c: New test case to check consistency and |
| | 1108 | expected usage of jit_arg_register_p. |
| | 1109 | |
| | 1110 | * check/Makefile.am: Update for new test case. |
| | 1111 | |
| | 1112 | 2015-01-17 Paulo Andrade <pcpa@gnu.org> |
| | 1113 | |
| | 1114 | * include/lightning/jit_aarch64.h, |
| | 1115 | include/lightning/jit_alpha.h, |
| | 1116 | include/lightning/jit_arm.h, |
| | 1117 | include/lightning/jit_hppa.h, |

| | 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> |
| | 1153 | |
| | 1154 | * configure.ac, lib/jit_disasm.c: Rewrite workaround |
| | 1155 | to apparent problem to initialize powerpc disassembler. |
| | 1156 | |
| | 1157 | 2015-01-15 Paulo Andrade <pcpa@gnu.org> |
| | 1158 | |

| | 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. |
| | 1171 | |
| | 1172 | * check/Makefile.am, check/lightning.c: Update for the |
| | 1173 | new test case and 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 |
| | 1196 | offsets. |
| | 1197 | |
| | 1198 | 2014-12-26 Paulo Andrade <pcpa@gnu.org> |
| | 1199 | |
| | 1200 | * lib/jit_ppc-cpu.c, lib/jit_ppc.c: Correct some endianess issues |
| | 1201 | on the powerpc le backend. |
| | 1202 | |
| | 1203 | 2014-12-26 Paulo Andrade <pcpa@gnu.org> |
| | 1204 | |
| | 1205 | * lib/jit_ppc-cpu.c: Add mcrxr instruction emulation, |
| | 1206 | as this instruction has been phased out, and should be |
| | 1207 | implemented as a kernel trap. |
| | 1208 | |
| | 1209 | 2014-12-26 Paulo Andrade <pcpa@gnu.org> |
| | 1210 | |

| | 1213 | |
| | 1214 | 2014-12-25 Paulo Andrade <pcpa@gnu.org> |

| | 1216 | * include/lightning.h: Split jit_htonr in the new 3 interfaces |
| | 1217 | jit_htonr_us, jit_htonr_ui and jit_htonr_ul, the later only |
| | 1218 | available on 64 bit. The plain/untyped jit_htonr macro call |

| | 1242 | tested on Gentoo default/linux/amd64/13.0/x32 profile. |
| | 1243 | |
| | 1244 | 2014-12-24 Paulo Andrade <pcpa@gnu.org> |
| | 1245 | |
| | 1246 | * lib/jit_names.c: Add missing rsbi_f and rsbi_d strings. |
| | 1247 | |
| | 1248 | 2014-12-21 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 |
| | 1263 | registers that may incorrectly remove a jit_movr under |
| | 1264 | special conditions. |
| | 1265 | |
| | 1266 | 2014-11-20 Paulo Andrade <pcpa@gnu.org> |
| | 1267 | |
| | 1268 | * include/lightning/jit_ppc.h, lib/jit_ppc-cpu.c, |
| | 1269 | lib/jit_ppc.c: Add initial powerpc le support. |
| | 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. |
| | 1287 | |
| | 1288 | 2014-11-08 Paulo Andrade <pcpa@gnu.org> |
| | 1289 | |
| | 1290 | * include/lightning/jit_private.h, lib/jit_aarch64.c, |

| | 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> |

| | 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, |
| | 1393 | lib/jit_aarch64-cpu.c, lib/jit_aarch64-fpu.c, lib/jit_aarch64-sz.c, |

| | 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 | |
| | 1433 | * lib/jit_aarch64-cpu.c, lib/jit_alpha-cpu.c, lib/jit_arm-cpu.c, |
| | 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, |
| | 1440 | lib/jit_alpha.c, lib/jit_arm.c, lib/jit_hppa.c, lib/jit_ia64.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 | |

| | 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> |

| | 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 | |

| | 1646 | include/lightning/jit_private.h, lib/Makefile.am, |

| | 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> |

| | 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> |

| | 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 |

| | 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. |

| | 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. |

| | 2507 | |
| | 2508 | * lib/jit_arm.c, lib/jit_ppc.c: Do not rely on __clear_cache |

| | 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. |

| | 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> |

| | 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 | |

| | 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 | |

| | 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 | |

| | 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. |

| | 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> |

| | 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. |

| | 3381 | index register; |
| | 3382 | |
| | 3383 | * check/ldst.inc: New file with common definition for all the |

| | 3386 | check/Makefile.am, check/ldsti.tst, check/ldstr.tst, |

| | 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> |

| | 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, |

| | 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> |

| | 3514 | * lib/jit_ppc.c: Assign copyright ownership to FSF. |

| | 3517 | generating code with reversed register arguments. |

| | 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. |

| | 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, |

| | 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, |
| | 3604 | include/lightning/Makefile.am, include/lightning/jit_arm.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. |

| | 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. |

| | 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 | |

| | 3806 | |
| | 3807 | * lightning/ppc/funcs.h (jit_flush_code): modified the computation |
| | 3808 | of start/end. The pointer arithmetic was done without casting. It |
| | 3809 | prevented compilation with recent gcc versions. |
| | 3810 | * lightning/ppc/core.h (jit_pushr_i): The offset for the store was |
| | 3811 | incorrect. Should have been 4 bytes below SP (not above). |
| | 3812 | * lightning/ppc/core.h (jit_popr_i): The offset for the load was |
| | 3813 | incorrect. Should have been 0 (not +8). |

| | 3829 | the core.h has no effect on the 32-bit backend. |
| | 3830 | * lightning/i386/core-64.h: Place JIT_R1/JIT_R2 in R10/R11, |

| | 3840 | |
| | 3841 | * lightning/i386/core-64.h (jit_movi_l): When the operand is 0, |
| | 3842 | the XOR should be on a quadword. |
| | 3843 | * lightning/i386/core-64.h (jit_prolog): Keep 16-byte stack |
| | 3844 | alignment. |
| | 3845 | (jit_ret): Always use LEAVE. |
| | 3846 | |
| | 3847 | 2008-06-13 Laurent Michel <ldm@thorgal.homelinux.org> |
| | 3848 | |
| | 3849 | * lightning/i386/core-64.h: Add (void) casts for C++ compatibility. |
| | 3850 | * lightning/i386/asm.h: Likewise. |
| | 3851 | |
| | 3852 | 2008-06-12 Paolo Bonzini <bonzini@gnu.org> |
| | 3853 | |

| | 3855 | * lightning/i386/core-32.h: ... here. |
| | 3856 | * lightning/i386/core-64.h: ... and here. Avoid dancing between |

| | 3859 | 2008-06-11 Paolo Bonzini <bonzini@gnu.org> |
| | 3860 | |
| | 3861 | * build-aux/lightning.m4: Adjust LIGHTNING_BACKENDS, don't |
| | 3862 | use suffix support to distinguish i386/x86_64. |
| | 3863 | * lightning/i386/Makefile.frag: Use LIGHTNING_TARGET_FILES |
| | 3864 | to distribute *-32.h and *-64.h files now. |
| | 3865 | * lightning/i386/asm-i386: Moved to... |
| | 3866 | * lightning/i386/asm.h: Include the appropriate subtarget file. |
| | 3867 | * lightning/i386/core-i386: Moved to... |

| | 3882 | |
| | 3883 | * lightning/i386/core-32.h: Use MOVLir instead of jit_movi_l |
| | 3884 | to implement jit_movi_p. |
| | 3885 | |
| | 3886 | 2008-06-11 Paolo Bonzini <bonzini@gnu.org> |
| | 3887 | |
| | 3888 | * lightning/i386/core-32.h: Use separate __APPLE__ and SysV |

| | 4603 | |
| | 4604 | * lightning/asm-common.h: change the 'pc' field of _jit to |
| | 4605 | be a union of various data types, because ISO C99 doesn't |

| | 4607 | _jit.pc to be _jit.x.uc_pc, _jit.x.us_pc, etc. |
| | 4608 | * all files: change all non-cast instances of _jit.pc to be |
| | 4609 | _jit.x.pc. |
| | 4610 | * lightning/i386/core.h: remove casts from jit_might. |
