| 3 | * include/lightning/jit_loongarch.h, lib/jit_loongarch-cpu.c, | |
| 4 | lib/jit_loongarch-fpu.c, lib/jit_loongarch-sz.c, lib/jit_loongarch.c: | |
| 5 | New files implementing the first version of the new loongarch port. | |
| 6 | * check/float.tst: Add preprocessor checks for NaN and +-Inf | |
| 7 | values converted to integers for loongarch. | |
| 8 | * configure.ac: Add check and conditionals for new architecture. | |
| 9 | * include/lightning.h.in, check/lightning.c, | |
| 10 | include/lightning/Makefile.am, include/lightning/jit_private.h, | |
| 11 | lib/Makefile.am, lib/jit_size.c, lib/lightning.c: Update for new | |

| 16 | * check/lightning.c: Remove -Dmacro=value from usage and attempt | |
| 17 | to parse it. It was buggy and not properly implemented. Now | |
| 18 | it pass any extra options to the generated jit. To pass any | |
| 19 | option starting with '-' need to also use '--'. | |
| 20 | * check/collatz.e: New sample file showing an example of jit | |
| 21 | generation. | |
| 22 | ||
| 23 | 2022-10-04 Paulo Andrade <pcpa@gnu.org> | |
| 24 | ||
| 25 | * include/lightning/jit_private.h: Add new flag to jit_block_t. | |
| 26 | * lib/lightning.c: Rewrite register liveness and state at block | |
| 27 | entry code to avoid a very expensive and non scaling code path. | |
| 28 | Now it attempts to do as few as possible recomputations when | |
| 29 | merging state of adjacent blocks, still doing one extra nop pass | |
| 30 | (in the sense that it will not find any changes) to make sure the | |
| 31 | logic is correct. | |

| 35 | * include/lightning/jit_private.h: Implement new data structures | |
| 36 | specific to riscv. | |
| 37 | * lib/jit_disasm.c: Extra disassemble code for riscv constant pool. | |
| 38 | * lib/jit_riscv-cpu.c: Modify movi to use constant pool if 3 or | |
| 39 | more instructions are required to construct constant and modify | |
| 40 | movi_p to use a pc relative load from a constant pool. | |
| 41 | lib/jit_riscv-sz.c: Update for new constant pool code. Most | |
| 42 | instructions that need 64 bit constants are significantly reduced. | |
| 43 | * lib/jit_riscv.c: Implement most of the constant pool code. | |
| 44 | * lib/jit_size.c: Update for estimate of code generation size. | |
| 45 | * lib/lightning.c: Update for riscv specific code, and also make | |
| 46 | sure to mprotect the constant pool as executable. | |

| 51 | pthreads. | |
| 52 | * check/Makefile.am: Update for new cas{r,i} simple test. | |
| 53 | * check/catomic.c, check/catomic.ok: New test case for | |
| 54 | simple compare and swap atomic operation. | |
| 55 | * check/lightning.c: Add entries to be able to use | |
| 56 | the new compare and swap atomic operation. Still missing | |
| 57 | a general test, only the basic C version. | |
| 58 | * include/lightning.h.in: Include pthread.h, even if not | |
| 59 | needing a fallback compare and swap. | |
| 60 | * include/lightning/jit_private.h: Add support for a register pair | |
| 61 | in second argument. Required by the new casr and casi operations. | |
| 62 | * lib/jit_aarch64-cpu.c, lib/jit_aarch64-sz.c, lib/jit_aarch64.c, | |

| 64 | lib/jit_x86-sz.c, lib/jit_x86.c: Implement inline code for compare | |
| 65 | and swap. | |
| 66 | * lib/jit_arm-cpu.c, lib/jit_arm-sz.c, lib/jit_arm.c: Implement | |
| 67 | inline code for compare and swap if cpu is armv7, otherwise, use | |
| 68 | a fallback with pthreads. | |

| 75 | lib/jit_sparc-cpu.c, lib/jit_sparc-sz.c, lib/jit_sparc.c: Implement | |
| 76 | fallback compare and swap with pthreads. At least some of these | |
| 77 | should be updated for inline code generation. | |
| 78 | * lib/jit_names.c, lib/jit_print.c: lib/lightning.c: Update for the | |
| 79 | new compare and swap operation. | |
| 80 | * doc/body.texi: Add simple documentation of the compare and swap | |
| 81 | new operation. | |

| 90 | * include/lightning.h.in: Reorder jit_mov{n,z}r in instruction list. | |
| 91 | * lib/jit_alpha.c, lib/jit_alpha-cpu.c, lib/jit_hppa.c, | |
| 92 | lib/jit_hppa-cpu.c, lib/jit_ia64.c, lib/jit_ia64-cpu.c, | |

| 94 | lib/jit_s390-cpu.c, lib/jit_sparc.c, lib/jit_sparc-cpu.c: | |
| 95 | Implement fallback jit_mov{n,z}r. These are a somewhat cheap | |
| 96 | implementation, but should be reviewed for the arches that already | |
| 97 | have a proper conditional move. | |
| 98 | * lib/jit_arm-sz.c, lib/jit_mips-sz.c: Add missing maximum size | |
| 99 | estimative and reorder. | |
| 100 | * lib/jit_aarch64-sz.c, lib/jit_x86-sz.c, lib/jit_ppc-sz.c: | |
| 101 | Reorder entry to match definition order. | |

| 104 | lib/jit_sparc-sz.c: Add heuristic value, basically the sum of | |
| 105 | the cost of a movr + beqr. | |
| 106 | * lib/jit_names.c: Add entries for debug output of mov{n,z}r. | |
| 107 | * lib/lightning.c: Use proper bitmask in jit_classify. | |

| 110 | ||
| 111 | * check/Makefile.am: Add test for the live instruction. | |
| 112 | * check/live.ok: New file. | |
| 113 | * check/live.tst: New file. | |
| 114 | * doc/body.texi: Add documentation for the live instruction and | |
| 115 | for jit_get_reg/jit_get_unreg. Fix menu entries. | |
| 116 | * include/lightning.h.in (jit_get_reg, jit_unget_reg): Expose the | |
| 117 | macros in the public header file. | |
| 118 | * include/lightning/jit_private.h (jit_get_reg, jit_unget_reg): | |
| 119 | Remove the macros from the private header file. | |
| 120 | ||
| 121 | 2021-04-03 Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de> | |
| 122 | ||
| 123 | * Makefile.am, check/Makefile.am, doc/Makefile.am, | |
| 124 | lib/Makefile.am: Include $(top_builddir)/include in include paths | |
| 125 | for the autoconf-generated header file lightning.h. | |
| 126 | ||
| 127 | 2021-04-03 Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de> | |
| 128 | ||
| 129 | * doc/.gitignore: Add version.texi to list of ignored files. | |
| 130 | * doc/version.texi: Remove file from version control. | |
| 131 | ||
| 132 | 2020-18-04 Paulo Andrade <pcpa@gnu.org> | |
| 133 | ||
| 134 | * lib/jit_x86-cpu.c, lib/jit_x86.c: Implement %rip relative | |
| 135 | calls and jumps on x86_64. Currently very conservative, assuming | |
| 136 | a jit block can be larger than 2G, so, if a jump or call is in | |
| 137 | the same jit generation, but target is unknown, use an indirect | |
| 138 | branch (could have an option to assume a jit code block is | |
| 139 | never larger than 2G). Also a deoptimization is that now does | |
| 140 | not always generate ip relative jmpi; previously implicitly | |
| 141 | assumed jmpi would never be larger than 2G. Overall still an | |
| 142 | optimization. | |

144 | 2020-23-01 Paulo Andrade <pcpa@gnu.org> |
| 145 | ||
| 146 | * lib/lightning.c: Add a proper fix to the condition of considering | |
| 147 | a register dead at entry of a block when it modifies the register | |
| 148 | !after! a branch to a target where it is live. | |
| 149 | The correction is just to split blocks on branches. It uses an | |
| 150 | extra label per branch, but makes following the code simpler and | |
| 151 | avoid costly searches. | |
| 152 | ||
| 153 | 2020-22-01 Paulo Andrade <pcpa@gnu.org> | |
| 154 | ||
| 155 | * lib/lightning.c: Correct a special condition of a register | |
| 156 | only assigned in a block, and incorrectly marked as dead before | |
| 157 | a jump where the register is live. | |
| 158 | ||
| 159 | 2019-10-04 Paulo Andrade <pcpa@gnu.org> | |
| 160 | ||
| 161 | * check/lightning.c, include/lightning/jit_private.h, | |
| 162 | include/lightning/jit_x86.h, lib/jit_x86-cpu.c, lib/jit_x86-sz.c, | |
| 163 | lib/jit_x86.c: Correct issues with MinGW64 that defines _WIN32 | |
| 164 | and needs long long for jit_word_t. | |
| 165 | ||
| 166 | 2019-09-16 Paulo Andrade <pcpa@gnu.org> | |
| 167 | ||
| 168 | * lib/lightning.c: Do not add registers that are never modified | |
| 169 | to the set of registers to scan for live range, what might | |
| 170 | consume a lot of cpu time, doing nothing. | |
| 171 | ||

| 4a71579b PC |
173 | |
| 174 | * include/lightning/jit_x86.h, lib/jit_x86.c: Correct x86_64 | |
| 175 | backend, made %r12 a callee-save register as dictated by the | |
| 176 | System V AMD64 ABI. | |
| 177 | ||
| 178 | 2019-09-16 Paulo Andrade <pcpa@gnu.org> | |
| 179 | ||
| 180 | * Makefile.am: Do not force CFLAGS for the get_jit_size target. | |
| 181 | * check/lightning.c: Drop __ppc__ check. | |
| 182 | * include/lightning.h.in: Drop __ppc__ check. Add new | |
| 183 | jit_flag_vararg flag, for special case in powerpc 32 bit using | |
| 184 | the SYSV abi, and need to pass an extra argument during code | |
| 185 | generation. | |
| 186 | * include/lightning/jit_ppc.c: Drop __ppc_ check. Remove the | |
| 187 | ABI_ELFv2 macro, as it now directly checks for the _CALL_ELF | |
| 188 | value when/if appropriate. | |
| 189 | * include/lightning/jit_private.h: Drop __ppc_ check. Check for | |
| 190 | _CALL_AIXDESC to define extra data to handle function | |
| 191 | descriptors. | |
| 192 | * lib/jit_ppc-cpu.c: Update to check for _CALL_SYSV; assume | |
| 193 | !_CALL_SYSV == (_CALL_AIX || _CALL_LINUX). Significant code | |
| 194 | rework for the SYSV abi. | |
| 195 | * lib/jit_ppc-sz.c: Update for the SYSV abi. | |
| 196 | * lib/jit_ppc.c: Update for the SYSV abi. Add matching va_list | |
| 197 | type. Drop __ppc__ check. | |
| 198 | * lib/jit_size.c: Drop __ppc_ check. | |
| 199 | * lib/lightning.c: Drop __ppc__ check. Add proper check for | |
| 200 | __powerpc__ and _CALL_AIXDESC to manage function descriptors. | |
| 201 | * lib/size.c: Update to drop __pppc_ check and SYSV abi. | |
| 202 | ||
| 203 | 2019-08-30 Paulo Andrade <pcpa@gnu.org> | |
| 204 | ||
| 205 | * lib/jit_mips-cpu.c: Use JALR to get the same effect as JR, as | |
| 206 | in mips32r6 JR generates an illegal instruction. Thanks to | |
| 207 | Bruno Haible for providing a patch and the information, reported at | |
| 208 | https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=925129 | |
| 209 | * THANKS: update. | |

| 4a71579b PC |
212 | |
| 213 | * include/lightning/jit_private.h: Move definition of offsetof | |
| 214 | from the public header file here. | |
| 215 | ||
| 216 | * configure.ac, include/Makefile.am, include/lightning.h, | |
| 217 | include/lightning.h.in: Generate lightning.h from lightning.in.h | |
| 218 | and remove the dependence on config.h from the public header file. | |
| 219 | ||
| 220 | 2019-06-04 Paulo Andrade <pcpa@gnu.org> | |
| 221 | ||
| 222 | * include/lightning/jit_riscv.h, lib/jit_riscv-cpu.c, | |
| 223 | lib/jit_riscv-fpu.c, lib/jit_riscv-sz.c, lib/jit_riscv.c: | |
| 224 | Implement riscv port. Only 64 bit Linux supported. Built on | |
| 225 | Fedora 28 image. | |
| 226 | ||
| 227 | * check/all.tst, check/float.tst, configure.ac, include/lightning.h, | |
| 228 | include/lightning/Makefile.am, include/lightning/jit_private.h, | |
| 229 | lib/Makefile.am, lib/jit_disasm.c, lib/jit_size.c, lib/lightning.c: | |
| 230 | Minor updates for the new riscv port. | |
| 231 | ||
| 232 | 2019-06-04 Paulo Andrade <pcpa@gnu.org> | |
| 233 | ||
| 234 | * lib/jit_alpha.c lib/jit_ia64.c lib/jit_mips.c lib/jit_sparc.c: | |
| 235 | Correct assertion of _jitc->regarg after emiting an instruction. | |
| 236 | jit_carry may be set, but not an argument to the current instruction. | |
| 237 | ||
| 238 | 2019-06-01 Paulo Andrade <pcpa@gnu.org> | |
| 239 | ||
| 240 | * lib/lightning.c: Correct assertion on jit_unget_reg when the | |
| 241 | argument is jit_carry, and jit_carry was not used in the | |
| 242 | instruction. | |
| 243 | ||
| 244 | 2019-06-01 Paulo Andrade <pcpa@gnu.org> | |
| 245 | ||
| 246 | * include/lightning/jit_private.h: Remove no longer need | |
| 247 | setmask field of jit_block_t and blockmask from jit_compiler_t. | |
| 248 | ||
| 249 | * lib/lightning.c: Rework of register live and unknown state | |
| 250 | information during jit generation. It no longer recurses nor | |
| 251 | do dangerous bit unset of registers in unknown state. The | |
| 252 | only pitfall known, that must be taken care now is that jmpr | |
| 253 | (or jmpi to not a jit node) is treated as a function call, as | |
| 254 | otherwise it would need to consider all registers live, and | |
| 255 | spill/reload during all jit generation. | |
| 256 | ||
| 257 | 2018-12-28 Paulo Andrade <pcpa@gnu.org> | |
| 258 | ||
| 259 | * lib/jit_disasm.c: Release bfd handle. Thanks for patch to | |
| 260 | Marc Nieper-Wißkirchen. | |
| 261 | ||
| 262 | 2018-08-30 Paulo Andrade <pcpa@gnu.org> | |
| 263 | ||
| 264 | * lib/jit_disasm.c: Add hints to select hppa disassembler. | |
| 265 | ||
| 266 | * lib/jit_hppa-cpu.c: Correct address of vastart when all | |
| 267 | argument registers were used as non vararg arguments. | |
| 268 | ||
| 269 | * lib/jit_hppa-fpu.c: Disable load/store of rv,ix,rb where | |
| 270 | rv is the value, ix is an register or integer offset and rb | |
| 271 | is a base register. These should be better tested, as they do | |
| 272 | not work on all environments (fail on qemu-hppa). | |
| 273 | ||
| 274 | 2018-04-20 Paulo Andrade <pcpa@gnu.org> | |
| 275 | ||
| 276 | * include/lightning/jit_private.h: Add new register classes to | |
| 277 | flag float registers and double only registers, required for sparc64 | |
| 278 | where only low 32 bit fpr registers can be used for single precision | |
| 279 | operations. | |
| 280 | Add new 128 bit jit_regset_t type for sparc64 register set. | |
| 281 | ||
| 282 | * include/lightning/jit_sparc.h, lib/jit_sparc-cpu.c, lib/jit_sparc-fpu.c, | |
| 283 | lib/jit_sparc-sz.c, lib/jit_sparc.c: Update for 64 bits sparc. | |
| 284 | ||
| 285 | * lib/lightning.c: Update for new jit_regset_t required for sparc64. | |
| 286 | ||
| 287 | 2018-02-26 Paulo Andrade <pcpa@gnu.org> | |
| 288 | ||
| 289 | * check/lightning.c, include/lightning.h: Add the new jit_va_push | |
| 290 | interface. That should be called when passing a va_list to a C | |
| 291 | function. This is required because on Alpha a va_list is passed | |
| 292 | by value, and lightning does not know about data types, so, cannot | |
| 293 | understand it is pushing a va_list as argument. | |
| 294 | ||
| 295 | * lib/jit_names.c, lib/lightning.c: Minor changes for the new | |
| 296 | jit_code_va_push. | |
| 297 | ||
| 298 | * check/cva_list.c: Update only test case using jit_va_push, to | |
| 299 | pass a va_list to a C function. | |
| 300 | ||
| 301 | doc/body.texi: Better documentation of the varargs interface. | |
| 302 | ||
| 303 | * jit_alpha.c, jit_alpha-cpu.c: Update to properly push a | |
| 304 | C va_list and correctly calculate varargs offset. | |
| 305 | ||
| 306 | * lib/jit_aarch64-sz.c, lib/jit_aarch64.c, lib/jit_alpha-sz.c, | |
| 307 | lib/jit_arm-sz.c, lib/jit_arm.c, lib/jit_hppa-sz.c, lib/jit_hppa.c, | |
| 308 | lib/jit_ia64-sz.c, lib/jit_ia64.c, lib/jit_mips-sz.c, lib/jit_mips.c, | |
| 309 | lib/jit_ppc-sz.c, lib/jit_ppc.c, lib/jit_s390-sz.c, lib/jit_s390.c, | |
| 310 | lib/jit_sparc-sz.c, lib/jit_sparc.c, lib/jit_x86-sz.c, lib/jit_x86.c: | |
| 311 | Update for the new jit_va_push interface. | |
| 312 | ||
| 313 | 2018-02-22 Paulo Andrade <pcpa@gnu.org> | |
| 314 | ||
| 315 | * lib/jit_alpha-cpu.c: Always set t12 to the address of the | |
| 316 | current function, to properly work on all systems. Previously | |
| 317 | the shortcut did only work on Tru64. For Linux and glibc the | |
| 318 | change is required. | |
| 319 | ||
| 320 | 2018-02-22 Paulo Andrade <pcpa@gnu.org> | |
| 321 | ||
| 322 | * lib/jit_aarch64.c, lib/jit_alpha.c, lib/jit_arm.c, | |
| 323 | lib/jit_mips.c, lib/jit_ppc.c, lib/jit_sparc.c, lib/jit_x86.c: | |
| 324 | Correct wrong logic in usage of jit_live in jit_retr. The | |
| 325 | problem is that if a temporary is required during epilog, | |
| 326 | the return register might be allocated, so, jit_live must always | |
| 327 | be used. | |
| 328 | ||
| 329 | 2018-01-31 Paulo Andrade <pcpa@gnu.org> | |
| 330 | ||
| 331 | * lib/lightning.c: Avoid deep recursions when computing live | |
| 332 | register ranges. | |
| 333 | ||
| 334 | 2018-01-31 Paulo Andrade <pcpa@gnu.org> | |
| 335 | ||
| 336 | * lib/jit_mips-cpu.c: Correct frame size and varargs | |
| 337 | initialization for the n32 abi. | |
| 338 | * lib/jit_mips.c, lib/jit_mips-fpu.c: Correct 32 bit abis | |
| 339 | in big-endian. | |
| 340 | ||
| 341 | 2017-09-13 Paulo Andrade <pcpa@gnu.org> | |
| 342 | ||
| 343 | * configure.ac: Add check for binutils 2.29 prototype to the | |
| 344 | disassembler function. | |
| 345 | * lib/jit_disasm.c: Adapt for binutils 2.29 change. | |
| 346 | ||
| 347 | 2017-06-09 Paulo Andrade <pcpa@gnu.org> | |
| 348 | ||
| 349 | * include/lightning/jit_private.h, lib/lightning.c: Add a | |
| 350 | second pass from start when computing register live ranges. | |
| 351 | This should be used temporarily, and is required for certain | |
| 352 | loop constructs, with several consecutive blocks not referencing | |
| 353 | a live register. | |
| 354 | ||
| 355 | 2016-05-05 Paulo Andrade <pcpa@gnu.org> | |
| 356 | ||
| 357 | * lib/lightning.c: Correct wrong movr simplification, | |
| 358 | remove no longer needed code to set return registers live | |
| 359 | and update live register set when reaching a label boundary, | |
| 360 | but do not descend if the block has been already visited. | |
| 361 | The later need some tuning for complex code generation, where | |
| 362 | it will still have issues. | |
| 363 | ||
| 364 | 2015-11-30 Paulo Andrade <pcpa@gnu.org> | |
| 365 | ||
| 366 | * doc/body.texi: Change documentation to no longer say | |
| 367 | it is a variant of the Fibonacci sequence, and document | |
| 368 | a proper implementation. | |
| 369 | Thanks to Jon Arintok for pointing out that the Fibonacci | |
| 370 | sequence generation was incorrect. It was documented, but | |
| 371 | still confusing. | |
| 372 | ||
| 373 | * check/fib.tst, check/fib.ok, check/bp.tst, check/bp.ok, | |
| 374 | doc/ifib.c, doc/rbif.c: Implement a proper Fibonacci | |
| 375 | sequence implementation. | |
| 376 | ||
| 377 | 2015-07-03 Paulo Andrade <pcpa@gnu.org> | |
| 378 | ||
| 379 | * lib/jit_mips-cpu.c: Correct definition of htonr_ul. | |
| 380 | Correct prolog/epilog/va* routines to work on o64 abi. | |
| 381 | ||
| 382 | * lib/jit_mips-fpu.c: Correct load of double literal | |
| 383 | argument when not using a data buffer. | |
| 384 | Remove alignment correction in vaarg_d if using the | |
| 385 | new mips abi. | |
| 386 | ||
| 387 | * lib/jit_mips.c: Correct code to allow creating variadic | |
| 388 | jit functions when using the new mips abi. | |
| 389 | ||
| 390 | * lib/jit_rewind.c: Minor adjust for rewind when using | |
| 391 | the new mips abi, if there are varargs arguments in | |
| 392 | registers. | |
| 393 | ||
| 394 | 2015-06-06 Paulo Andrade <pcpa@gnu.org> | |
| 395 | ||
| 396 | * lib/jit_ia64-cpu.c: Search backward for the last output | |
| 397 | register used, otherwise would stop too early if a float | |
| 398 | argument used the slot. | |
| 399 | Correct offset of first va_list argument, and use proper | |
| 400 | va_list abi. | |
| 401 | ||
| 402 | * lib/jit_ia64-fpu.c: Add new functions to move a gpr | |
| 403 | to a fpr register, to counterpart the ones that move a | |
| 404 | fpr to a gpr. These are required to properly implement | |
| 405 | jit_getarg*_{f,d} on complex prototypes, or variadic | |
| 406 | jit functions. | |
| 407 | ||
| 408 | * lib/jit_ia64-sz.c: Update for support to jit variadic | |
| 409 | functions. | |
| 410 | ||
| 411 | * lib/jit_ia64.c: Implement proper abi for variadic | |
| 412 | jit functions. | |
| 413 | ||
| 414 | 2015-06-04 Paulo Andrade <pcpa@gnu.org> | |
| 415 | ||
| 416 | * lib/jit_rewind.c: New file implementing generic functions | |
| 417 | to "rewind", or rewrite IR code sequences. | |
| 418 | ||
| 419 | * include/lightning.h: Add several new codes, that previously | |
| 420 | were a function call, that would synthesize the operation. | |
| 421 | Now, there is a code for the operation, and a new flag to | |
| 422 | know an operation is synthesized. | |
| 423 | ||
| 424 | * include/lightning/jit_private.h: Add several new macros to | |
| 425 | help construct synthesized IR code sequences. | |
| 426 | ||
| 427 | * lib/Makefile.am: Update for lib/jit_rewind.c. | |
| 428 | ||
| 429 | * lib/jit_disasm.c: Update for a small rework on jit_node_t, | |
| 430 | so that --enable-devel-disassembler does not need a change | |
| 431 | in the layout of jit_node_t. | |
| 432 | ||
| 433 | * lib/jit_names.c: Update for the new codes. | |
| 434 | ||
| 435 | * lib/jit_print.c: Update to print more readable output, and | |
| 436 | flag synthesized IR code sequences. | |
| 437 | ||
| 438 | * lib/jit_aarch64-sz.c, lib/jit_aarch64.c, | |
| 439 | lib/jit_arm-sz.c, lib/jit_arm.c, lib/jit_x86-sz.c, | |
| 440 | lib/jit_x86.c: Update for new synthesized IR code sequences. | |
| 441 | ||
| 442 | * lib/jit_ppc-cpu.c, lib/jit_ppc-fpu., lib/jit_ppc-sz.c, | |
| 443 | lib/jit_ppc.c, lib/jit_mips-cpu.c, lib/jit_mips-fpu.c, | |
| 444 | lib/jit_mips-sz.c, lib/jit_mips.c, lib/jit_s390-fpu.c, | |
| 445 | lib/jit_s390-sz.c, lib/jit_s390.c: Update for new synthesized | |
| 446 | IR code sequences and correct bugs in the initial varargs | |
| 447 | implementation support. | |
| 448 | ||
| 449 | * lib/jit_alpha-sz.c, lib/jit_alpha.c, lib/jit_hppa-sz.c, | |
| 450 | lib/jit_hppa.c, lib/jit_ia64-sz.c, lib/jit_ia64.c, | |
| 451 | lib/jit_sparc-sz.c, lib/jit_sparc.c: Add generic, untested | |
| 452 | support for the new synthesized IR code sequences. Known | |
| 453 | most likely broken right now, and should be corrected once | |
| 454 | access to these hosts is available. | |
| 455 | ||
| 456 | * lib/lightning.c: Update for new IR codes, and add support | |
| 457 | for not yet existing instructions that change third argument. | |
| 458 | ||
| 459 | * size.c: Change to use different tables for LE and BE PowerPC. | |
| 460 | Correct a wrong endif for x32. | |
| 461 | ||
| 462 | 2015-05-25 Paulo Andrade <pcpa@gnu.org> | |
| 463 | ||
| 464 | * check/cva_list.c: New file implementing a test to ensure | |
| 465 | the value returned by jit_va_start is a valid C va_list. | |
| 466 | ||
| 467 | * check/va_list.ok: New simple helper file, as now the | |
| 468 | va_list.tst test is enabled. | |
| 469 | ||
| 470 | * check/va_list.tst: Rewritten for an extensive variadic | |
| 471 | jit functions test. | |
| 472 | ||
| 473 | * check/Makefile.am: Update for the new tests. | |
| 474 | ||
| 475 | * lib/jit_arm-cpu.c, lib/jit_arm-swf.c, lib/jit_arm-vfp.c, | |
| 476 | lib/jit_arm.c: Correct broken software float in a previous | |
| 477 | commit. Note that the hard float abi implementation is known | |
| 478 | broken at this time, for special cases involving variadic | |
| 479 | functions, and should be corrected next. | |
| 480 | ||
| 481 | lib/jit_x86-cpu.c, lib/jit_x86-sz.c, lib/jit_x86.c: Correct | |
| 482 | the jit_va_list_t semantics to match C va_list. | |
| 483 | ||
| 484 | 2015-05-24 Paulo Andrade <pcpa@gnu.org> | |
| 485 | ||
| 486 | * lib/Makefile.am: Bump library major. This is a preparation | |
| 487 | for a rework that was due for quite some time, but that is | |
| 488 | now required to properly implement variadic jit functions. | |
| 489 | The rework is mainly required to know at prolog parsing, if | |
| 490 | a function is variadic or not. This will benefit a few | |
| 491 | backends, and is mandatory for the hard float arm abi. | |
| 492 | The rework was already planned for quite some time, to | |
| 493 | be able to use a variable stack framesize, and for leaf | |
| 494 | functions optimization where applicable. | |
| 495 | The change will be source compatible, but will change | |
| 496 | some internals, and jit_code_t values, as some new will | |
| 497 | be added. | |
| 498 | The only behavior change is that, jit_arg_register_p may | |
| 499 | change return value on hard float arm abi, if called before | |
| 500 | or after jit_ellipsis. Common sense anyway, would say to | |
| 501 | make that call after jit_ellipsis, but documentation | |
| 502 | should be updated for it. | |
| 503 | ||
| 504 | 2015-05-24 Paulo Andrade <pcpa@gnu.org> | |
| 505 | ||
| 506 | * lib/jit_aarch64-fpu.c, lib/jit_aarch64.c: Correct base | |
| 507 | aarch64 varargs code. | |
| 508 | ||
| 509 | 2015-05-24 Paulo Andrade <pcpa@gnu.org> | |
| 510 | ||
| 511 | * check/lightning.c: Clearly run check if clang is the system | |
| 512 | compiler. | |
| 513 | ||
| 514 | 2015-05-20 Paulo Andrade <pcpa@gnu.org> | |
| 515 | ||
| 516 | * lib/jit_sparc-cpu.c, lib/jit_sparc-fpu.c, lib/jit_sparc.c: | |
| 517 | Add base support to jit vararg functions to the sparc backend. | |
| 518 | ||
| 519 | 2015-05-20 Paulo Andrade <pcpa@gnu.org> | |
| 520 | ||
| 521 | * lib/jit_alpha-cpu.c, lib/jit_alpha-fpu.c, lib/jit_alpha.c: | |
| 522 | Add base support to jit vararg functions to the alpha backend. | |
| 523 | ||
| 524 | 2015-05-19 Paulo Andrade <pcpa@gnu.org> | |
| 525 | ||
| 526 | * lib/jit_hppa-cpu.c, lib/jit_hppa-fpu.c, lib/jit_hppa.c: | |
| 527 | Add base support to jit vararg functions to the hppa backend. | |
| 528 | ||
| 529 | 2015-05-10 Paulo Andrade <pcpa@gnu.org> | |
| 530 | ||
| 531 | * lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c, lib/jit_ia64.c: | |
| 532 | Add base support to jit vararg functions to the ia64 backend. | |
| 533 | ||
| 534 | 2015-05-10 Paulo Andrade <pcpa@gnu.org> | |
| 535 | ||
| 536 | * lib/jit_ia64-fpu.c, lib/jit_ia64.c: Correct movi_d_w | |
| 537 | and movi_f_w implementation to work when not using a | |
| 538 | data buffer. This causes the check varargs.tst to | |
| 539 | work when passing "-d" to the lightning test tool. | |
| 540 | ||
| 541 | 2015-05-10 Paulo Andrade <pcpa@gnu.org> | |
| 542 | ||
| 543 | * lib/jit_ia64.c: Implement inline assembly cache flush, | |
| 544 | required on multiprocessor systems. | |
| 545 | ||
| 546 | 2015-05-06 Paulo Andrade <pcpa@gnu.org> | |
| 547 | ||
| 548 | * lib/jit_mips-cpu.c, lib/jit_mips-fpu.c, lib/jit_mips.c: | |
| 549 | Add base support to jit vararg functions to the mips backend. | |
| 550 | Currently only supported on the o32 abi, until access to a | |
| 551 | n32 system is arranged. | |
| 552 | ||
| 553 | 2015-05-05 Paulo Andrade <pcpa@gnu.org> | |
| 554 | ||
| 555 | * lib/jit_ppc-cpu.c, lib/jit_ppc-fpu.c, lib/jit_ppc.c: | |
| 556 | Add base support to jit vararg functions to the PowerPC backend. | |
| 557 | ||
| 558 | 2015-05-02 Paulo Andrade <pcpa@gnu.org> | |
| 559 | ||
| 560 | * lib/jit_s390-cpu.c, lib/jit_s390-fpu.c, lib/jit_s390.c: | |
| 561 | Add base support to jit vararg functions to the s390 backend. | |
| 562 | ||
| 563 | 2015-05-01 Paulo Andrade <pcpa@gnu.org> | |
| 564 | ||
| 565 | * lib/jit_arm-cpu.c, lib/jit_arm-swf.c, lib/jit_arm-vfp.c, | |
| 566 | lib/jit_arm.c: Add base support to jit vararg | |
| 567 | functions to the arm backend. | |
| 568 | ||
| 569 | 2015-04-30 Paulo Andrade <pcpa@gnu.org> | |
| 570 | ||
| 571 | * lib/jit_aarch64-cpu.c, lib/jit_aarch64-fpu.c, | |
| 572 | lib/jit_aarch64.c: Add base support to jit vararg | |
| 573 | functions to the aarch64 backend. | |
| 574 | ||
| 575 | 2015-04-27 Paulo Andrade <pcpa@gnu.org> | |
| 576 | ||
| 577 | * include/lightning.h, include/lightning/jit_private.h, | |
| 578 | lib/jit_names.c, lib/lightning.c: Add initial support | |
| 579 | for the new jit_va_start, jit_va_arg, jit_va_arg_d, and | |
| 580 | jit_va_end interfaces. The jit_va_start call is supposed | |
| 581 | to return a va_list compatible pointer, but not yet | |
| 582 | decided if it will be "declared" stdarg compatible, | |
| 583 | as for now only x86 support has been added (and should | |
| 584 | be compatible), but issues may arise on other backends. | |
| 585 | ||
| 586 | * check/lightning.c: Add wrappers to call the new jit_va_* | |
| 587 | interfaces. | |
| 588 | ||
| 589 | * lib/jit_x86-cpu.c, lib/jit_x86.c: Implement the new | |
| 590 | jit_va_* for x86. | |
| 591 | ||
| 592 | * lib/jit_x86-sz.c: Add fields, but not yet fully updated, | |
| 593 | as this is an intermediate commit. | |
| 594 | ||
| 595 | * lib/jit_aarch64-sz.c, lib/jit_aarch64.c, | |

| 602 | lib/jit_s390-sz.c, lib/jit_s390.c, | |
| 603 | lib/jit_sparc-sz.c, lib/jit_sparc.c: Prepare for the | |
| 604 | new jit_va_* interfaces. Not yet implemented, and will | |
| 605 | cause an assertion if used. | |
| 606 | ||
| 607 | * check/va_list.tst: Simple early test case, that works | |
| 608 | on x86_64, x32, ix86, cygwin, and cygwin64. | |
| 609 | ||
| 610 | 2015-02-17 Paulo Andrade <pcpa@gnu.org> | |
| 611 | ||
| 612 | * include/lightning.h, include/lightning/jit_private.h, | |

| 614 | lib/jit_alpha-cpu.c, lib/jit_alpha.c, | |

| 621 | lib/jit_sparc-cpu.c, lib/jit_sparc.c, | |
| 622 | lib/jit_x86-cpu.c, lib/jit_x86.c: Implement the new | |
| 623 | jit_allocar(offs, size) interface, that receives | |
| 624 | two integer registers arguments, allocates space | |
| 625 | dynamically in the stack, returns the offset in | |
| 626 | the first argument, and uses the second argument | |
| 627 | for the size in bytes of the memory to be allocated. | |
| 628 | ||
| 629 | * check/allocar.ok, check/allocar.tst: New files | |
| 630 | implementing test cases for the new jit_allocar | |
| 631 | interface. | |
| 632 | ||
| 633 | * check/Makefile.am, check/lightning.c: Update for | |
| 634 | the new test case and interface. | |
| 635 | ||
| 636 | * doc/body.texi: Add documentation of the new | |
| 637 | interface. | |
| 638 | ||
| 639 | 2015-02-17 Paulo Andrade <pcpa@gnu.org> | |
| 640 | ||
| 641 | * include/lightning/jit_x86.h, lib/jit_x86-cpu.c, | |
| 642 | lib/jit_x86-x87.c: No longer make st(7) available. | |
| 643 | Need to keep one x87 slots empty to avoid exceptions. | |
| 644 | This has the side effect of no longer needing the | |
| 645 | hackish emms instruction before a function call. | |
| 646 | ||
| 647 | 2015-02-16 Paulo Andrade <pcpa@gnu.org> | |
| 648 | ||
| 649 | * lib/lightning.c: Remove the jit_regno_patch bitfield | |
| 650 | register fields before actual emit, as it is only really | |
| 651 | used before emit, otherwise, on special conditions it | |
| 652 | may consider live registers as dead during code emit. | |
| 653 | ||
| 654 | 2015-02-15 Paulo Andrade <pcpa@gnu.org> | |
| 655 | ||
| 656 | * lib/jit_x86-cpu.c, lib/jit_x86-sse.c, lib/jit_x86-x87.c: | |
| 657 | Correct encoding of ldxr* stxr* in the x32 abi. If the | |
| 658 | displacement register is negative, it would generate | |
| 659 | a 64 bit instruction with a 32 bit unsigned displacement. | |
| 660 | ||
| 661 | * check/ranger.tst, check/ranger.ok: New files, implementing | |
| 662 | a test case for negative loads and stores. This is range.tst | |
| 663 | converted to use registers instead of immediate offsets. | |
| 664 | ||
| 665 | check/Makefile.am: Update for the new test case. | |
| 666 | ||
| 667 | 2015-02-07 Paulo Andrade <pcpa@gnu.org> | |
| 668 | ||
| 669 | * lib/jit_size.c: Preventively use at least 144 bytes | |
| 670 | if JIT_INSTR_MAX is less than it. The logic is not | |
| 671 | guaranteed to be 100% precise, it is mostly heuristics | |
| 672 | to allocate a buffer with as close as possible size, | |
| 673 | but a wrong value may cause code generation to write | |
| 674 | past the end of the buffer. | |
| 675 | ||
| 676 | 2015-02-03 Paulo Andrade <pcpa@gnu.org> | |
| 677 | ||
| 678 | * lib/lightning.c: Correct the reason the bug in | |
| 679 | simplify_stxi was not triggered before, it was due to | |
| 680 | incorrectly resetting the value->code field, what was | |
| 681 | causing it to never properly optimize: | |
| 682 | stxi Im0 Rb0 Rt0 | |
| 683 | ldxi Rt1 Rb1 Im1 | |
| 684 | when Rb0 == Rb1, Rt0 == Rt1 and Im0 == Im1 | |
| 685 | There was another possible issue, that has been also | |
| 686 | addressed in this commit, that would be the case of | |
| 687 | Rbn == Rtn, where no redundancy removal is possible. | |
| 688 | ||
| 689 | 2015-02-03 Paulo Andrade <pcpa@gnu.org> | |
| 690 | ||
| 691 | * lib/lightning.c: Correct wrong check in simplify_stxi. | |
| 692 | The test was incorrectly comparing the target register | |
| 693 | and the displacement offset. This was a time bomb bug, | |
| 694 | that would trigger in code like: | |
| 695 | stxi Im0 Rb0 Rt0 | |
| 696 | stxi Im1 Rb1 Rt1 | |
| 697 | if Rb0 == Rb1 && Rt0 == Rt1 && Im0 == Rt1, that is, | |
| 698 | the wrong check was Im0 == Rt1, instead of the supposed | |
| 699 | Im0 == Imm1 (that was what the code mean't to do). It | |
| 700 | was removing the second stxi assuming it was redundantly | |
| 701 | generated; as that is not uncommon pattern on | |
| 702 | translators generating jit. | |
| 703 | ||
| 704 | 2015-02-02 Paulo Andrade <pcpa@gnu.org> | |
| 705 | ||
| 706 | * configure.ac, include/lightning/jit_private.h, | |
| 707 | lib/jit_aarch64.c, lib/jit_alpha.c, lib/jit_arm.c, | |
| 708 | lib/jit_disasm.c, lib/jit_hppa.c, lib/jit_ia64.c, | |
| 709 | lib/jit_mips.c, lib/jit_ppc.c, lib/jit_print.c, | |
| 710 | lib/jit_s390.c, lib/jit_sparc.c, lib/jit_x86.c: Add a new | |
| 711 | --enable-devel-disassembler option, that should be used | |
| 712 | during development, or lightning debug. This option | |
| 713 | intermixes previous jit_print and jit_disassemble | |
| 714 | output, making it easier to visualize what lightning | |
| 715 | call was used, and what code was generated. | |
| 716 | ||
| 717 | 2015-01-31 Paulo Andrade <pcpa@gnu.org> | |
| 718 | ||
| 719 | * lib/jit_arm-cpu.c, lib/jit_arm.c: Only limit to 24 bit | |
| 720 | displacement non conditional jump in the same jit_state_t. | |
| 721 | ||
| 722 | 2015-01-19 Paulo Andrade <pcpa@gnu.org> | |
| 723 | ||
| 724 | * doc/body.texi: Reorder documentation, making jit_frame | |
| 725 | and jit_tramp the lightning response to the need of | |
| 726 | trampolines, continuations and tail call optimizations. | |
| 727 | A pseudo code example of a factorial function was added. | |
| 728 | Also added a section for description of the available | |
| 729 | predicates. | |
| 730 | ||
| 731 | * doc/fact.c: New file, implementing a simple example of | |
| 732 | a translation of a trivial, recursive, tail call optimization | |
| 733 | into lightning calls. This is the conversion to functional C | |
| 734 | code of the example in doc/body.texi. | |
| 735 | ||
| 736 | * doc/Makefile.am: Update for the next test case. | |

| 743 | lib/jit_ppc.c, lib/jit_s390.c, lib/jit_sparc.c, | |
| 744 | lib/jit_x86.c: Add the new jit_arg_register_p predicate. | |
| 745 | The predicate is expected to be used to know if an | |
| 746 | argument is in a register, what would need special | |
| 747 | handling if code that can overwrite non callee save | |
| 748 | registers is executed. | |
| 749 | ||
| 750 | * check/carg.c: New test case to check consistency and | |
| 751 | expected usage of jit_arg_register_p. | |
| 752 | ||
| 753 | * check/Makefile.am: Update for new test case. | |
| 754 | ||

| 769 | lib/jit_ppc.c, lib/jit_s390.c, | |
| 770 | lib/jit_sparc.c, lib/jit_x86.c: Remove jit_arg_reg_p and | |
| 771 | jit_arg_f_reg_p from a public header, and define it only | |
| 772 | on port specific files where an integer offset is used | |
| 773 | to qualify an argument identifier. Exported code expects | |
| 774 | an opaque pointer (but of jit_node_t* type) to "qualify" | |
| 775 | an argument identifier. | |
| 776 | This patch, and the code review/simplification done during | |
| 777 | it also corrected some bugs: | |
| 778 | o Inconsistent jit_arg_d value of double argument after 3 | |
| 779 | integer arguments in arm for jit_functions; tested, C | |
| 780 | functions were being properly called. | |
| 781 | o Inconsistent use of getarg_{f,d} and putarg*_{f,d} on | |
| 782 | s390 (32-bit) that happened to not have a proper test | |
| 783 | case, as it would only happen for jit functions, and | |
| 784 | tested, called C functions had proper arguments. | |
| 785 | o Corrected a "last minute" correction that did not go | |
| 786 | to the committed version, and would not compile on hppa, | |
| 787 | due to bad _jit_putargi_d prototype definition. | |
| 788 | ||
| 789 | 2015-01-17 Paulo Andrade <pcpa@gnu.org> | |
| 790 | ||
| 791 | * doc/body.texi: Correct wrong/outdated information for | |
| 792 | hton*, pusharg* and ret*, and add missing documentation | |
| 793 | for rsb*, qmul*, qdvi* and putarg*. | |
| 794 | ||

| 805 | lib/jit_s390.c, lib/jit_sparc.c, lib/jit_x86.c: | |
| 806 | Implement jit_putarg*. It works as a mix of jit_getarg* | |
| 807 | and jit_pusharg*, in the way that the first argument is | |
| 808 | a register or immediate, and the second is a pointer | |
| 809 | returned by jit_arg*. The use of the interface is to change | |
| 810 | values of arguments to the current jit function. | |
| 811 | ||
| 812 | * check/put.ok, check/put.tst: New test cases exercising | |
| 813 | the new jit_putarg* interface. | |

| 834 | lib/jit_s390x.c, lib/jit_size.c, lib/lightning.c: | |
| 835 | Add support for generating jit for s390 32 bit. This change | |
| 836 | also removed %f15 from the list of temporaries fpr registers; | |
| 837 | it was not being used, but if were, it would corrupt the | |
| 838 | stack frame because the spill address would overwrite grp | |
| 839 | offsets. | |

| 851 | ||
| 852 | 2014-12-26 Paulo Andrade <pcpa@gnu.org> | |

| 891 | 2014-12-21 Paulo Andrade <pcpa@gnu.org> | |
| 892 | ||
| 893 | * lib/jit_arm.c: Call __clear_cache for every page. | |
| 894 | This should only be required for older boards or | |
| 895 | toolchain setup, but has been reported to be required | |
| 896 | for lightning at some point. | |
| 897 | ||
| 898 | 2014-12-21 Paulo Andrade <pcpa@gnu.org> | |
| 899 | ||
| 900 | * lib/jit_arm.c: Correct check to guard overflow of index | |

| 902 | ||
| 903 | 2014-11-24 Paulo Andrade <pcpa@gnu.org> | |
| 904 | ||
| 905 | * lib/lightning.c: Remove an optimization to calee save | |

| 908 | ||
| 909 | 2014-11-20 Paulo Andrade <pcpa@gnu.org> | |

| 914 | 2014-11-20 Paulo Andrade <pcpa@gnu.org> | |
| 915 | ||
| 916 | * lib/jit_disasm.c: Change thumb or arm disassemble based on | |
| 917 | jit code before disassembly. | |
| 918 | ||
| 919 | * lib/jit_arm-cpu.c: Correct reversed arguments to LDRD and | |
| 920 | STRD instructions, and correct checking for support of those. | |
| 921 | ||
| 922 | * lib/jit_arm-swf.c: Correct wrong use of LDRD and STRD and | |
| 923 | only use those if the register is even. | |
| 924 | ||
| 925 | * check/check.arm.swf.sh, check/check.arm4.swf.sh: New files | |
| 926 | to test LDRD and STRD, as well as the alternate code path | |
| 927 | when those are not available, in the .arm4. test case. | |
| 928 | ||

| 936 | lib/jit_s390x.c, lib/jit_sparc.c, lib/jit_x86.c: | |
| 937 | Implement a private jit_flush call, that flushes | |
| 938 | the cache, if applicable, aligning down to the | |
| 939 | previous and up to the next page boundary. | |
| 940 | ||
| 941 | 2014-11-08 Paulo Andrade <pcpa@gnu.org> | |
| 942 | ||
| 943 | * check/ctramp.c: New file. It just repeats the test | |
| 944 | of tramp.tst, but using two jit_state_t, what should | |
| 945 | test possible issues with two contexts, and also validate | |
| 946 | jit_tramp works on backends with function descriptions. | |
| 947 | ||
| 948 | * check/Makefile.am: Update for new test case. | |
| 949 | ||
| 950 | 2014-11-03 Paulo Andrade <pcpa@gnu.org> | |
| 951 | ||
| 952 | * include/lightning/jit_mips.h: Do not make the t9 register | |
| 953 | JIT_R11 (or JIT_R7 for n32 or n64 abi) available. Previously | |
| 954 | it cause problems if one expects it to not be changed in a | |
| 955 | function call. For example, calling a jit function, where it | |
| 956 | really does not need to be changed. | |
| 957 | ||
| 958 | 2014-10-26 Paulo Andrade <pcpa@gnu.org> | |

| 962 | lib/jit_s390x.c, lib/jit_sparc.c, lib/jit_x86.c: Add an | |
| 963 | assertion to all code generation "drivers" to ensure | |
| 964 | _jitc->regarg is empty or in an expected state, after | |
| 965 | translation of a lightning instruction to native code. | |
| 966 | This change was a brute force test to find out other cases | |
| 967 | of a temporary not being release (like was happening with | |
| 968 | _bmsi and _bmci on x86), but no other case was found, | |
| 969 | after running make check, with assertions enabled, on all | |
| 970 | backends. | |
| 971 | ||
| 972 | 2014-10-26 Paulo Andrade <pcpa@gnu.org> | |
| 973 | ||
| 974 | * lib/jit_x86-cpu.c: Correct a register allocation leak in | |
| 975 | _bmsi and _bmci. | |
| 976 | ||
| 977 | 2014-10-25 Paulo Andrade <pcpa@gnu.org> | |
| 978 | ||
| 979 | * lib/jit_disasm.c: Do not cause an fatal error if init_jit | |
| 980 | fails in the jit_init_debug call. | |
| 981 | ||
| 982 | 2014-10-24 Paulo Andrade <pcpa@gnu.org> | |
| 983 | ||
| 984 | * lib/jit_ia64.c, lib/jit_ppc.c: Correct handling of function | |
| 985 | descriptor when first prolog is a jit_tramp prolog. The | |
| 986 | test case was using the same jit_context_t, so was not | |
| 987 | triggering this condition. | |
| 988 | ||
| 989 | * lib/jit_ppc-cpu.c: Properly handle jump displacements that | |
| 990 | do not fit on 24 powerpc. This required changing from previous | |
| 991 | "mtlr reg, blr" to "mtctr reg, bctr" to properly handle | |
| 992 | the logic to "hide" function descriptors, but that would | |
| 993 | also be required as the proper jit_jmpr when/if implementing | |
| 994 | optimizations to leaf functions (was working with blr because | |
| 995 | it is saved/reloaded in prolog/epilog). | |
| 996 | ||
| 997 | 2014-10-21 Paulo Andrade <pcpa@gnu.org> | |
| 998 | ||
| 999 | * include/lightning.h, lib/lightning.c: Add three predicates | |
| 1000 | to query information about labels. jit_forward_p(label) | |
| 1001 | will return non zero if the label is "forward", that is | |
| 1002 | need a call to jit_link(label), jit_indirect_p(label) | |
| 1003 | that returns non zero if the label was created with the | |
| 1004 | jit_indirect() call, and jit_target_p(label) that will | |
| 1005 | return non zero if there is at least one jump patched | |
| 1006 | to land at that label. | |
| 1007 | ||
| 1008 | 2014-10-18 Paulo Andrade <pcpa@gnu.org> | |
| 1009 | ||
| 1010 | * check/range.ok, check/range.tst: New test case designed | |
| 1011 | to catch incorrect code generation, usually due to incorrect | |
| 1012 | test of immediate size. The test checks a large amount of | |
| 1013 | encodings in "power of two" boundaries. This test exorcises | |
| 1014 | a significant amount of code paths that was previously not | |
| 1015 | tested. | |
| 1016 | ||
| 1017 | * check/Makefile.am: Add range test to make check target. | |
| 1018 | ||
| 1019 | * lib/jit_aarch64-cpu.c: Correct wrong address calculation | |
| 1020 | for stxi_c, stxi_s, stxi_i and stxi_l when the offset is | |
| 1021 | too large. | |
| 1022 | ||
| 1023 | * lib/jit_mips-fpu.c: Correct wrong size test to check if | |
| 1024 | an immediate can be encoded in a float or double store. | |
| 1025 | ||
| 1026 | * lib/jit_s390x-cpu.c: Correct inverted encoding to stxi_s | |
| 1027 | when the offset cannot be encoded, and fallbacks to an | |
| 1028 | alternate encoding in 2 instructions. | |
| 1029 | ||
| 1030 | 2014-10-17 Paulo Andrade <pcpa@gnu.org> | |
| 1031 | ||
| 1032 | * check/alu_rsb.ok, check/alu_rsb.tst: New files implementing | |
| 1033 | tests for jit_rsb*. | |
| 1034 | ||
| 1035 | * check/Makefile.am, check/lightning.c, include/lightning.h, | |

| 1050 | lib/jit_x86.c, lib/lightning.c: Implement jit_rsb*. This | |
| 1051 | was a missing lightning 1.x interface, that on most | |
| 1052 | backends is synthesized, but on a few backends (hppa and ia64), | |
| 1053 | it can generate better code as on those there is, or the | |
| 1054 | only instruction with an immediate is in "rsb" format | |
| 1055 | (left operand). | |

| 1057 | 2014-10-17 Paulo Andrade <pcpa@gnu.org> | |

| 1061 | ||
| 1062 | * size.c: Modified to append the code name in a C comment | |
| 1063 | after the maximum instruction size. | |

| 1078 | lib/jit_sparc-cpu.c: Implement or correct the internal | |
| 1079 | nop(count) call that receives an argument that tells the | |
| 1080 | modulo bytes to align the code for the next instruction. | |

| 1085 | lib/jit_x86.c: Implement the new jit_align() call that receive | |
| 1086 | an argument, that tells the modulo, in bytes, to align the | |
| 1087 | next instruction. In most backends the only value that makes | |
| 1088 | a difference is a value that matches sizeof(void*), as all | |
| 1089 | other values usually are already automatically aligned in | |
| 1090 | labels, but not guaranteed to be aligned at word size bytes. | |
| 1091 | ||
| 1092 | * check/align.ok, check/align.tst: New files, implementing | |
| 1093 | a simple test for the new jit_align() interface. | |
| 1094 | ||
| 1095 | * check/Makefile.am, check/lightning.c, lib/jit_aarch64-sz.c, | |

| 1101 | ||
| 1102 | 2014-10-13 Paulo Andrade <pcpa@gnu.org> | |
| 1103 | ||
| 1104 | * include/lightning.h, lib/jit_size.c, size.c: Use a | |
| 1105 | symbolic value for the last IR code. | |
| 1106 | ||
| 1107 | 2014-10-12 Paulo Andrade <pcpa@gnu.org> | |
| 1108 | ||
| 1109 | * include/lightning.h, include/lightning/jit_private.h, | |
| 1110 | lib/jit_aarch64-cpu.c, lib/jit_alpha-cpu.c, lib/jit_arm-cpu.c, | |
| 1111 | lib/jit_hppa-cpu.c, lib/jit_ia64-cpu.c, lib/jit_mips-cpu.c, | |

| 1113 | lib/jit_x86-cpu.c, lib/lightning.c: Implement the new | |
| 1114 | jit_frame and jit_tramp interfaces, that allow writing | |
| 1115 | trampoline like calls, where a single dispatcher jit buffer | |
| 1116 | is written, and later other jit buffers are created, with | |
| 1117 | the same stack frame layout as the dispatcher. This is the | |
| 1118 | logic that GNU Smalltalk used in lightning 1.x, and is required | |
| 1119 | to make a sane port for lighting 2.x. | |
| 1120 | ||
| 1121 | * jit_ia64-cpu.c: Implement support for jit_frame and jit_tramp, | |
| 1122 | and also correct wrong encoding for B4 instructions, that | |
| 1123 | implement jmpr, as well as correct reverse logic in _jmpr, | |
| 1124 | that was moving the branch register to the jump register, | |
| 1125 | and not vice-versa. | |
| 1126 | Also, if a stack frame is to be assumed, always assume it may | |
| 1127 | call a function with up to 8 arguments, regardless of the | |
| 1128 | hint frame argument. | |
| 1129 | ||
| 1130 | * lib/jit_arm.c: Add a new must_align_p() interface to ensure | |
| 1131 | function prologs are always aligned. This condition was | |
| 1132 | previously always true, somewhat by accident, but with | |
| 1133 | jit_tramp it is not guaranteed. | |
| 1134 | ||
| 1135 | * jit_ia64-cpu.c: lib/jit_ppc.c: Add minor special handling | |
| 1136 | required to implement jit_tramp, where a function descriptor | |
| 1137 | should not be added before a prolog, as jit_tramp means omit | |
| 1138 | prolog. | |
| 1139 | ||
| 1140 | * check/lightning.c: Update test driver for the new interfaces. | |
| 1141 | ||
| 1142 | * check/Makefile.am, check/tramp.tst, check/tramp.ok: Add | |
| 1143 | a simple test and example of the jit_frame and jit_tramp | |
| 1144 | usage implementing a simple Fibonacci function using a | |
| 1145 | simulation of an interpreter stack and how it would handle | |
| 1146 | state in language specific variables. | |
| 1147 | ||
| 1148 | * doc/body.texi: Add documentation for jit_frame and | |
| 1149 | jit_tramp. | |
| 1150 | ||

| 1155 | lib/jit_ppc.c, lib/jit_s390x.c, lib/jit_sparc.c, | |
| 1156 | lib/jit_x86.c, lib/lightning.c: Allow jit_jmpi on a | |
| 1157 | target that is not a node. This may lead to hard to | |
| 1158 | debug code generation, but is a required feature for | |
| 1159 | certain generators, like the ones that used lightning | |
| 1160 | 1.2x. Note that previously, but not really well | |
| 1161 | documented, it was instructed to use: | |
| 1162 | jit_movi(rn, addr); jit_jmpr(rn); | |
| 1163 | but now, plain: | |
| 1164 | jit_patch_abs(jit_jmpi(), addr); | |
| 1165 | should also work. | |
| 1166 | ||
| 1167 | 2014-09-24 Paulo Andrade <pcpa@gnu.org> | |
| 1168 | ||
| 1169 | * lib/jit_x86-sz.c: Generate information about instruction | |
| 1170 | lengths for more precise calculation of buffer size on | |
| 1171 | Windows x64. This change is specially important because | |
| 1172 | the maximum instruction length is larger than other | |
| 1173 | systems, what could cause an out of bounds write on | |
| 1174 | special conditions without this update. | |
| 1175 | ||
| 1176 | 2014-09-24 Paulo Andrade <pcpa@gnu.org> | |
| 1177 | ||
| 1178 | * check/lightning.c: Add workaround to conflicting global | |
| 1179 | optind variable in cygwin binutils that have an internal | |
| 1180 | getopt* implementation. | |
| 1181 | ||
| 1182 | * lib/jit_x86-cpu.c: Add a simple define ffsl ffs if building | |
| 1183 | for 32 bit and there is no ffsl function. | |
| 1184 | ||
| 1185 | 2014-09-24 Paulo Andrade <pcpa@gnu.org> | |
| 1186 | ||
| 1187 | * check/lightning.c: Add a hopefully temporary kludge to not use | |
| 1188 | sprintf and sscanf returned by dlsym. This is required to pass | |
| 1189 | the varargs test. | |
| 1190 | ||
| 1191 | * include/lightning/jit_private.h: Use symbolic name for first | |
| 1192 | integer register argument, as this is different in sysv and | |
| 1193 | win64 abi. | |
| 1194 | ||
| 1195 | * include/lightning/jit_x86.h: Add conditionals and definitions | |
| 1196 | for Windows x64 (under __CYGWIN__ preprocessor conditional). | |
| 1197 | ||
| 1198 | * lib/jit_x86-cpu.c: Correct one instruction encoding bug, that | |
| 1199 | was working by accident. Only use rax to rdx for some byte | |
| 1200 | operations to work on compatibility mode (that is, to generate | |
| 1201 | the proper encoding, instead of actually generating encoding | |
| 1202 | for high byte registers, e.g. %bh). | |
| 1203 | Add proper prolog and epilog for windows x64. | |
| 1204 | ||
| 1205 | * lib/jit_x86-sse.c: Correct a swapped rex prefix for float | |
| 1206 | operations. | |
| 1207 | ||
| 1208 | * lib/jit_x86.c: Adjust to support Windows x64 abi. | |
| 1209 | ||
| 1210 | * check/check.x87.nodata.sh: New file, previously used but that | |
| 1211 | was missing git. | |
| 1212 | ||
| 1213 | 2014-09-07 Paulo Andrade <pcpa@gnu.org> | |
| 1214 | ||
| 1215 | * lib/lightning.c: Mark all registers advertised as live, as | |
| 1216 | per jit_callee_save_p as live whenever reaching a jump that | |
| 1217 | cannot be tracked. This is a rethink of the previous commit, | |
| 1218 | and is a better approach, otherwise there would not be much | |
| 1219 | sense on relying on jit_callee_save_p if it could not be | |
| 1220 | trusted. | |
| 1221 | ||
| 1222 | * check/jmpr.tst, check/jmpr.ok: New files implementing a very | |
| 1223 | simple test case, that would actually cause an assertion on | |
| 1224 | code before the change to only mark as live when reaching a | |
| 1225 | jump that could not tracked, the actually advertised as callee | |
| 1226 | save registers. | |
| 1227 | ||
| 1228 | check/Makefile.am: Update for new jmpr test case. | |
| 1229 | ||
| 1230 | 2014-09-01 Paulo Andrade <pcpa@gnu.org> | |
| 1231 | ||
| 1232 | * lib/lightning.c: Do not mark all registers in unknown state | |
| 1233 | as live on jit_jmpr, or jit_jmpi to an absolute address. Instead, | |
| 1234 | treat it as a function call, and only consider JIT_Vn registers | |
| 1235 | as possibly live. | |
| 1236 | ||
| 1237 | 2014-08-29 Paulo Andrade <pcpa@gnu.org> | |

| 1254 | lib/jit_x86-cpu.c, lib/jit_x86-sse.c, | |
| 1255 | lib/jit_x86-x87.c: Review generation of all branch | |
| 1256 | instructions and always adds the jit_class_nospill | |
| 1257 | bitfield for temporary registers that cannot be spilled | |
| 1258 | because the reload would be after a conditional jump; the | |
| 1259 | patch only adds an extra assertion. These conditions do | |
| 1260 | not happen on documented lightning usage, but can happen | |
| 1261 | if one uses the not exported jit_get_reg and jit_unget_reg | |
| 1262 | calls and cause enough register starvation. | |
| 1263 | ||
| 1264 | 2014-08-16 Paulo Andrade <pcpa@gnu.org> | |
| 1265 | ||
| 1266 | * lib/jit_alpha.c: Correct wrong bitmask of most argument | |
| 1267 | float register arguments, that were being set as callee | |
| 1268 | save instead of argument registers class. | |
| 1269 | ||
| 1270 | 2014-08-16 Paulo Andrade <pcpa@gnu.org> | |

| 1274 | that implements "virtual" float registers in the stack | |
| 1275 | and operations as calls to libgcc. | |

| 1292 | ||
| 1293 | 2014-08-10 Paulo Andrade <pcpa@gnu.org> | |
| 1294 | ||
| 1295 | * lib/lightning.c: Always mark JIT_RET and JIT_FRET as | |
| 1296 | live in a function epilog. This is required because | |
| 1297 | on some ports a complex sequence, allocating one or more | |
| 1298 | registers, may be required to jump from a ret* to the | |
| 1299 | epilog, and the lightning api does not have annotations | |
| 1300 | to know if a function returns a value, or the type of | |
| 1301 | the return value. | |
| 1302 | ||
| 1303 | 2014-08-10 Paulo Andrade <pcpa@gnu.org> | |
| 1304 | ||
| 1305 | * lib/lightning.c: Change the correct live bitmask of | |
| 1306 | return registers after a function call in jit_update. | |
| 1307 | ||
| 1308 | 2014-08-10 Paulo Andrade <pcpa@gnu.org> | |
| 1309 | ||
| 1310 | * lib/lightning.c: Change assertions to have an int | |

| 1312 | ||
| 1313 | 2014-08-10 Paulo Andrade <pcpa@gnu.org> | |
| 1314 | ||
| 1315 | * lib/jit_aarch64.c: Correct bad setup for assertion | |
| 1316 | of consistency before a patch. | |
| 1317 | ||
| 1318 | 2014-08-10 Paulo Andrade <pcpa@gnu.org> | |
| 1319 | ||
| 1320 | * lib/jit_mips-cpu.c: Correct typo in the jit_bmsr | |
| 1321 | implementation that was using the wrong test result | |
| 1322 | register. | |
| 1323 | ||
| 1324 | 2014-07-28 Paulo Andrade <pcpa@gnu.org> | |
| 1325 | ||
| 1326 | * lib/jit_memory.c: Do not call free on NULL pointers. | |
| 1327 | ||
| 1328 | * include/lightning/jit_private.h, lib/jit_note.c, | |
| 1329 | lib/lightning.c: Add a wrapper to memcpy and memmove | |
| 1330 | to not actually call those functions with a zero size | |
| 1331 | argument, and likely also a null src or dst. | |
| 1332 | ||
| 1333 | 2014-07-27 Paulo Andrade <pcpa@gnu.org> | |
| 1334 | ||
| 1335 | * include/lightning/jit_private.h, lib/jit_disasm.c, | |
| 1336 | lib/lightning.c: Remove the global jit_progname variable. | |
| 1337 | It was being only used in jit_init_debug, that is called | |
| 1338 | from init_jit, so, just pass an argument. | |
| 1339 | ||
| 1340 | 2014-07-27 Paulo Andrade <pcpa@gnu.org> | |
| 1341 | ||
| 1342 | * doc/body.texi: Add note that jit_set_memory_functions | |
| 1343 | should be called before init_jit, because init_jit | |
| 1344 | itself may call the memory wrappers. | |
| 1345 | ||
| 1346 | 2014-04-22 Paulo Andrade <pcpa@gnu.org> | |

| 1359 | header file. These types and definitions are supposed to be | |
| 1360 | only used internally. | |
| 1361 | ||
| 1362 | 2014-04-05 Paulo Andrade <pcpa@gnu.org> | |
| 1363 | ||
| 1364 | * lib/jit_arm-cpu.c: Only adjust stack pointer in prolog if | |
| 1365 | need stack space, that is, do not emit a nop instruction | |
| 1366 | subtracting zero from the stack pointer. | |
| 1367 | ||
| 1368 | 2014-04-04 Paulo Andrade <pcpa@gnu.org> | |
| 1369 | ||
| 1370 | * lib/jit_disasm.c: Correct a crash in the doc/printf example | |
| 1371 | on arm due to releasing the data_info information in | |
| 1372 | jit_clear_state. This is a special case for arm only, and | |
| 1373 | actually, only armv5 or older uses the data_info buffer, | |
| 1374 | or when forcing arm instruction set mode besides thumb | |
| 1375 | available. | |
| 1376 | ||
| 1377 | 2014-12-03 Paulo Andrade <pcpa@gnu.org> | |

| 1384 | ||
| 1385 | * include/lightning.h, include/lightning/jit_private.h, | |
| 1386 | lib/lightning.c: Implement the new jit_set_data() interface, | |
| 1387 | and the new jit_get_data() helper. Like jit_set_code(), | |
| 1388 | jit_realize() should be called before jit_set_data(). | |
| 1389 | The most common usage should be jit_set_data(JIT_DISABLE_DATA | |
| 1390 | | JIT_DISABLE_NOTE), to force synthesize any float/double | |
| 1391 | constant in the stack and not generate any debug information. | |
| 1392 | ||
| 1393 | * lib/jit_note.c: Minor change to debug note generation as | |
| 1394 | now it uses an alternate temporary data buffer during constants | |
| 1395 | and debug generation to accommodate the possibility of the user | |
| 1396 | setting an alternate data buffer. | |

| 1403 | lib/jit_s390x-sz.c: Update for several instructions that now | |
| 1404 | have a different maximum length due to jit_set_data. | |
| 1405 | ||
| 1406 | * lib/jit_mips-fpu.c: Implement jit_set_data, but missing | |
| 1407 | validation on n32 and n64 abis (and/or big endian). | |
| 1408 | ||
| 1409 | * lib/jit_mips-sz.c: Update for changes in o32. | |
| 1410 | ||
| 1411 | * lib/jit_ppc-fpu.c: Implement jit_set_data, but missing | |
| 1412 | validation on Darwin PPC. | |

| 1415 | 64 bit. | |
| 1416 | ||
| 1417 | * lib/jit_ia64-fpu.c: Implement untested jit_set_data. | |
| 1418 | ||
| 1419 | * TODO: Add note to list ports that were not tested for the | |
| 1420 | new jit_set_data() feature, due to no longer having access | |
| 1421 | to them. | |
| 1422 | ||
| 1423 | * check/nodata.c: New file implementing a simple test exercising | |
| 1424 | several different conditions created by jit_set_data(). | |
| 1425 | ||
| 1426 | * check/check.nodata.sh: New file implementing a wrapper | |
| 1427 | over the existing *.tst files, that runs all tests without | |
| 1428 | using a data buffer for constants; only meaningful (and | |
| 1429 | enabled) on architectures that used to store float/double | |
| 1430 | constants on a read only data buffer. | |
| 1431 | ||
| 1432 | * configure.ac, check/Makefile.am: Update for the new test | |
| 1433 | cases. | |
| 1434 | ||
| 1435 | * check/lightning.c: Implement the new "-d" option that | |
| 1436 | sets an internal flag to call jit_set_data() disable | |
| 1437 | constants and debug, that is, using only a pure code | |
| 1438 | buffer. | |

| 1440 | 2014-11-03 Paulo Andrade <pcpa@gnu.org> | |
| 1441 | ||
| 1442 | * include/lightning.h, include/lightning/jit_private.h, | |
| 1443 | lib/lightning.c: Implement the new jit_set_code() interface, | |
| 1444 | that allows instructing lightning to use an alternate code | |
| 1445 | buffer. The new jit_realize() function should be called | |
| 1446 | before jit_set_code(), and usually call jit_get_code() | |
| 1447 | to query the amount of bytes expected to be required for | |
| 1448 | the code. | |
| 1449 | ||
| 1450 | * lib/jit_size.c: Minor update to have less chances of | |
| 1451 | miscalculating the code buffer by starting the counter | |
| 1452 | with the size of the longest instruction instead of zero, | |
| 1453 | as code emit fails if at any moment less than the longest | |
| 1454 | instruction bytes are available. | |
| 1455 | ||
| 1456 | * check/setcode.c: New file implementing some basic tests | |
| 1457 | of the new jit_set_code() interface. | |
| 1458 | ||
| 1459 | * check/Makefile.am: Update for newer test case. | |
| 1460 | ||
| 1461 | 2014-06-03 Paulo Andrade <pcpa@gnu.org> | |
| 1462 | ||
| 1463 | * include/lightning.h, lib/lightning.c: Add the new | |
| 1464 | jit_indirect() call, that returns a special label node, | |
| 1465 | and tells lightning that the label may be the target of | |
| 1466 | an indirect jump. | |
| 1467 | ||
| 1468 | * doc/body.texi: Document the new jit_indirect() call, and | |
| 1469 | add examples of different ways to create labels and branches. | |
| 1470 | ||
| 1471 | 2014-23-02 Paulo Andrade <pcpa@gnu.org> | |
| 1472 | ||
| 1473 | * lib/jit_x86.c: Rewrite previous patch to inline save/restore | |
| 1474 | because clobbering %ebx in x86 is treated as an error | |
| 1475 | (jit_x86.c:239:5: error: PIC register clobbered by 'ebx' in 'asm'). | |
| 1476 | ||
| 1477 | 2014-19-02 Paulo Andrade <pcpa@gnu.org> | |
| 1478 | ||
| 1479 | * lib/jit_x86.c: Rewrite incorrect inline assembly that could | |
| 1480 | truncate a variable in a callee save register. Now it simply | |
| 1481 | tells gcc that the register is clobbered, instead of using a | |
| 1482 | *32 bit* swap with a temporary variable. The problem only | |
| 1483 | happens when compiling with optimization. | |
| 1484 | ||
| 1485 | 2014-19-02 Paulo Andrade <pcpa@gnu.org> | |
| 1486 | ||
| 1487 | * include/lightning/jit_aarch64.h, include/lightning/jit_arm.h, | |
| 1488 | include/lightning/jit_hppa.h, include/lightning/jit_ia64.h, | |
| 1489 | include/lightning/jit_mips.h, include/lightning/jit_ppc.h, | |
| 1490 | include/lightning/jit_s390x.h, include/lightning/jit_sparc.h, | |
| 1491 | include/lightning/jit_x86.h: Change jit_regset_t to an | |
| 1492 | unsigned type, to allow safe right shift. | |
| 1493 | ||
| 1494 | * lib/lightning.c: Rewrite jit_regset_scan1 to allow easier | |
| 1495 | compiler optimization. | |
| 1496 | ||
| 1497 | 2013-12-03 Paulo Andrade <pcpa@gnu.org> | |
| 1498 | ||
| 1499 | * lib/jit_x86-x87.c: Correct wrong optimization when | |
| 1500 | loading the log(2) constant. | |
| 1501 | ||
| 1502 | 2013-12-03 Paulo Andrade <pcpa@gnu.org> | |
| 1503 | ||
| 1504 | * lib/jit_x86-cpu.c: Use the emms instruction before | |
| 1505 | calling any function. This is particularly important | |
| 1506 | when using c99 complex functions as it can easily | |
| 1507 | overflow the x87 stack due to the way lightning uses | |
| 1508 | the x87 stack as a flat register file. | |
| 1509 | ||
| 1510 | 2013-12-02 Paulo Andrade <pcpa@gnu.org> | |
| 1511 | ||
| 1512 | * lib/jit_x86-x87.c: Correct wrong code generation due | |
| 1513 | to comparing the base and not the value register with | |
| 1514 | %st(0) in stxi_f. | |
| 1515 | ||
| 1516 | 2013-12-02 Paulo Andrade <pcpa@gnu.org> | |
| 1517 | ||
| 1518 | * lib/jit_x86-x87.c, lib/jit_x86.c: Use 8 bytes aligned | |
| 1519 | stack offset for float/double x87 to/from sse move. | |
| 1520 | ||
| 1521 | 2013-11-27 Paulo Andrade <pcpa@gnu.org> | |
| 1522 | ||
| 1523 | * configure.ac, lib/jit_arm-swf.c, lib/jit_arm.c: Add | |
| 1524 | changes that should at least allow building lightning | |
| 1525 | on Apple iOS7. | |
| 1526 | ||
| 1527 | 2013-10-08 Paulo Andrade <pcpa@gnu.org> | |
| 1528 | ||
| 1529 | * lib/jit_ppc-cpu.c: Correct wrong shortcut for ldxi_l with | |
| 1530 | a zero offset, that was calling ldr_i instead of ldr_l. | |
| 1531 | ||
| 1532 | 2013-10-08 Paulo Andrade <pcpa@gnu.org> | |
| 1533 | ||
| 1534 | * include/lightning/jit_arm.h, lib/jit_arm-cpu.c: Do not use | |
| 1535 | by default load/store instructions that map to ldrt/strt. | |
| 1536 | There is already the long displacement version for positive | |
| 1537 | offsets, and when using a (shorter) negative offset it does | |
| 1538 | not map to ldrt/strt. At least on qemu strt may cause | |
| 1539 | reproducible, but unexpected SIGILL. | |
| 1540 | ||
| 1541 | 2013-10-08 Paulo Andrade <pcpa@gnu.org> | |
| 1542 | ||
| 1543 | * lib/jit_arm-vfp.c: Correct wrong load/store offset | |
| 1544 | calculation when the displacement is constant but too | |
| 1545 | large to use an instruction with an immediate offset. | |
| 1546 | ||
| 1547 | 2013-10-07 Paulo Andrade <pcpa@gnu.org> | |
| 1548 | ||
| 1549 | * check/self.c: Extend tests to validate jit_callee_save_p | |
| 1550 | does not cause an assertion on valid arguments, and test | |
| 1551 | extra registers defined on some backends. | |
| 1552 | ||
| 1553 | * configure.ac: Do not ignore environment CFLAGS when | |
| 1554 | checking if need to test runtime configurable options, | |
| 1555 | like use x87 when sse2 is available, arm instruction set | |
| 1556 | instead of thumb, etc. | |
| 1557 | ||
| 1558 | * include/lightning/jit_arm.h: Correct wrong jit_f macro | |
| 1559 | definition. | |
| 1560 | ||
| 519a9ea1 | 1561 | * include/lightning/jit_ia64.h, include/lightning/jit_ppc.h: |
| 4a71579b PC |
1562 | Correct wrong jit_r macro definition. |
| 1563 | ||
| 1564 | * lib/jit_x86-x87.c, lib/jit_x86.c: Actually use the | |
| 1565 | reserved stack space for integer to/from float conversion. | |
| 1566 | The stack space was also changed to ensure it is 8 bytes | |
| 1567 | aligned. Also, for Solaris x86 in 32 bit mode, an alternate | |
| 1568 | truncr_d was implemented because for some reason it is | |
| 1569 | failing with SIGILL if using the "fisttpl" instructions, | |
| 1570 | that must be available on p6 or newer, but for the sake of | |
| 1571 | making all tests pass, implement a 486 or newer sequence | |
| 1572 | if "sun" is defined. | |
| 1573 | ||
| 1574 | 2013-10-03 Paulo Andrade <pcpa@gnu.org> | |
| 1575 | ||
| 1576 | * include/lightning/jit_mips.h, lib/jit_mips-cpu.c, | |
| 1577 | lib/jit_mips-sz.c, lib/jit_mips.c, size: Build and | |
| 1578 | pass all test cases on Irix big endian mips using | |
| 1579 | the 64 bit abi. | |
| 1580 | ||
| 1581 | 2013-10-02 Paulo Andrade <pcpa@gnu.org> | |
| 1582 | ||
| 1583 | * include/lightning/jit_mips.h: Add proper mips abi detection. | |
| 1584 | ||
| 1585 | 2013-09-30 Paulo Andrade <pcpa@gnu.org> | |
| 1586 | ||
| 1587 | * lib/jit_print.c: Do not crash if calling jit_print from | |
| 1588 | gdb before actually emitting code. | |
| 1589 | ||
| 1590 | * lib/lightning.c: Correct misplaced check for already | |
| 1591 | visited blocks on conditional branches, what was preventing | |
| 1592 | proper merge live bit masks of forward blocks. | |
| 1593 | ||
| 1594 | 2013-09-30 Paulo Andrade <pcpa@gnu.org> | |
| 1595 | ||
| 1596 | * lib/jit_x86-cpu.c: Correct not properly tested case of using | |
| 1597 | %r12 as index register, what was causing an invalid assertion. | |
| 1598 | %r12 is mapped to the "extra" JIT_R3 register, and test cases | |
| 1599 | only test "standard" lightning registers. | |
| 1600 | ||
| 1601 | 2013-09-28 Paulo Andrade <pcpa@gnu.org> | |
| 1602 | ||
| 1603 | * lib/jit_ia64.c: Minor change to force collecting the maximum | |
| 1604 | instruction length in the --enable-devel-get-jit-size build | |
| 1605 | mode. The actual generated file did not change because the | |
| 1606 | sampling was large enough that it had already collected proper | |
| 1607 | information in the previously slightly buggy code (not forcing | |
| 1608 | a sync of the instructions that could be combined). | |
| 1609 | ||
| 1610 | 2013-09-27 Paulo Andrade <pcpa@gnu.org> | |
| 1611 | ||
| 1612 | * lib/jit_arm.c: Correct build when disassembler is | |
| 1613 | disabled. | |
| 1614 | ||
| 1615 | 2013-09-25 Paulo Andrade <pcpa@gnu.org> | |
| 1616 | ||
| 1617 | * lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c: Correct some | |
| 1618 | off by one range checks (that were only accepting values | |
| 1619 | one less than the maximum allowed) and an invalid test | |
| 1620 | condition check that was forcing it to always use | |
| 1621 | indirect jumps even when reachable with an immediate | |
| 1622 | displacement. | |
| 1623 | ||
| 1624 | 2013-09-24 Paulo Andrade <pcpa@gnu.org> | |
| 1625 | ||
| 1626 | * lib/jit_aarch64-sz.c, lib/jit_arm-sz.c, lib/jit_hppa-sz.c, | |
| 1627 | lib/jit_ia64-sz.c, lib/jit_mips-sz.c, lib/jit_ppc-sz.c, | |
| 1628 | lib/jit_s390x-sz.c, lib/jit_size.c, lib/jit_sparc-sz.c, | |
| 1629 | lib/jit_x86-sz.c: New files implementing static tables | |
| 1630 | with longest known instructions length generated to match | |
| 1631 | a lightning instruction. These tables should make it easier | |
| 1632 | to make it very unlikely to ever miscalculate, or by too | |
| 1633 | much, the size of a code buffer. | |
| 1634 | ||
| 1635 | * lib/jit_size.c: New file that aids to either collect | |
| 1636 | jit code size information, or use the information depending | |
| 1637 | on build options. | |
| 1638 | ||
| 1639 | * size.c: New helper file that parses input for, and create | |
| 1640 | an initial jit_$arch-sz.c file, that needs some minor edit | |
| 1641 | for arches with multiple configurations. | |
| 1642 | ||
| 1643 | * configure.ac, Makefile.am: Add the new, devel mode only | |
| 1644 | --enable-devel-get-jit-size configure option, that sets | |
| 1645 | compile time flags to collect jit code size information, | |
| 1646 | that will be used as input for the "noinst size program". | |
| 1647 | ||
| 1648 | * lib/jit_aarch64.c, lib/jit_arm.c, lib/jit_disasm.c, | |
| 1649 | lib/jit_hppa.c, lib/jit_ia64.c, lib/jit_memory.c, | |
| 1650 | lib/jit_mips.c, lib/jit_ppc.c, lib/jit_s390x.c, | |
| 1651 | lib/jit_sparc.c, lib/jit_x86.c, lib/lightning.c: Minor | |
| 1652 | changes for the --enable-devel-get-jit-size build mode, | |
| 1653 | as well as the "production build mode" with jit code | |
| 1654 | size information. | |
| 1655 | ||
| 1656 | 2013-09-14 Paulo Andrade <pcpa@gnu.org> | |
| 1657 | ||
| 1658 | * include/lightning.h, lib/lightning.c: Add the new | |
| 1659 | jit_pointer_p interface, that returns a boolean value | |
| 1660 | telling if the pointer argument is inside the jit | |
| 1661 | code buffer. This is useful to avoid the need to add | |
| 1662 | extra labels and calls to jit_address to figure bounds | |
| 1663 | of code buffer, and still keep internal data private. | |
| 1664 | ||
| 1665 | 2013-09-13 Paulo Andrade <pcpa@gnu.org> | |
| 1666 | ||
| 1667 | * include/lightning.h, include/lightning/jit_private.h, | |
| 1668 | lib/jit_note.c: Change the code argument of jit_get_note | |
| 1669 | to a jit_pointer_t and make jit_get_note a public interface. | |
| 1670 | It was intended so since start, as a way to map an offset | |
| 1671 | in the code to a function name, file name and line number | |
| 1672 | mapping. | |
| 1673 | ||
| 1674 | 2013-09-11 Paulo Andrade <pcpa@gnu.org> | |
| 1675 | ||
| 1676 | * doc/body.texi: Correct reversed arguments in example of | |
| 1677 | usage in a (possibly) multi threaded, multiple jit_state_t | |
| 1678 | environments. | |
| 1679 | ||
| 1680 | * include/lightning/jit_arm.h, include/lightning/jit_private.h, | |
| 1681 | lib/jit_arm-cpu.c, lib/jit_arm.c: Make a previously, non | |
| 1682 | documented, global state private to the related jit_state_t | |
| 1683 | generating code. | |
| 1684 | ||
| 1685 | 2013-09-10 Paulo Andrade <pcpa@gnu.org> | |
| 1686 | ||
| 1687 | * check/self.c, check/self.ok: New files implementing simple | |
| 1688 | consistency check assertions. At first validating some macros | |
| 1689 | that use values from different sources agree. | |
| 1690 | ||
| 1691 | * check/Makefile.am: Update for the new test case. | |
| 1692 | ||
| 1693 | * include/lightning.h, lib/lightning.c: Add the new | |
| 1694 | jit_callee_save_p() call, that is intended to be used when | |
| 1695 | writing complex code using lightning, so that one does not | |
| 1696 | need to verify what backend is being used, or have access to | |
| 1697 | private data, to query if a register is callee save or not; | |
| 1698 | on several backends the scratch registers are actually callee | |
| 1699 | save. | |
| 1700 | ||
| 1701 | * include/lightning/jit_aarch64.h, include/lightning/jit_arm.h, | |
| 1702 | include/lightning/jit_hppa.h, include/lightning/jit_mips.h, | |
| 1703 | include/lightning/jit_ppc.h, include/lightning/jit_sparc.h, | |
| 1704 | include/lightning/jit_x86.h: Add an explicit definition for | |
| 1705 | JIT_R3-JIT_Rn, JIT_V3-JIT_Vn and JIT_F6-JIT_Fn when applicable. | |
| 1706 | This allows one to write code based on "#if defined(JIT_XN)" | |
| 1707 | and therefore, not need to check what is the current backend | |
| 1708 | or have access to private data structures. This is particularly | |
| 1709 | useful when writing virtual machines with several specialized, | |
| 1710 | global registers. | |
| 1711 | ||
| 1712 | * lib/jit_ia64.c: Properly flag the callee save general | |
| 1713 | purpose registers as such, so that jit_callee_save_p() works | |
| 1714 | as intended. | |
| 1715 | ||
| 1716 | 2013-09-10 Paulo Andrade <pcpa@gnu.org> | |
| 1717 | ||
| 1718 | * check/lightning.c, configure.ac: Conditionally use the | |
| 1719 | code written to workaround a bug in the Hercules emulator, | |
| 1720 | as isnan and isinf are not available at least on HP-UX ia64. | |
| 1721 | ||
| 1722 | 2013-09-10 Paulo Andrade <pcpa@gnu.org> | |
| 1723 | ||
| 1724 | * lib/jit_s390x-cpu.c: Spill/reload correct callee save | |
| 1725 | float registers. | |
| 1726 | ||
| 1727 | 2013-09-10 Paulo Andrade <pcpa@gnu.org> | |
| 1728 | ||
| 1729 | * lib/jit_hppa-cpu.c: Correct code to call a function stored | |
| 1730 | in a register or a patched function address. | |
| 1731 | ||
| 1732 | 2013-09-10 Paulo Andrade <pcpa@gnu.org> | |
| 1733 | ||
| 1734 | * lib/jit_ia64-cpu.c: Correct incorrect logic when restoring | |
| 1735 | the value of the "r2" callee save register. | |
| 1736 | ||
| 1737 | 2013-08-29 Paulo Andrade <pcpa@gnu.org> | |
| 1738 | ||
| 1739 | * lib/jit_arm-cpu.c, lib/jit_arm.c: Correct wrong test and update | |
| 1740 | of the thumb offset information, when checking if needing to | |
| 1741 | patch a jump from arm to thumb mode. The problem would happen when | |
| 1742 | remapping the code buffer, and the new address being lower than | |
| 1743 | the previous one. | |
| 1744 | ||
| 1745 | 2013-08-26 Paulo Andrade <pcpa@gnu.org> | |
| 1746 | ||
| 1747 | * configure.ac: Extend FreeBSD test to also handle NetBSD. | |
| 1748 | ||
| 1749 | * lib/jit_x86-cpu.c: Correct wrongly defined offset type of | |
| 1750 | ldxi_ui. Problem detected when building on NetBSD. | |
| 1751 | ||
| 1752 | * lib/lightning.c: Adjust code to handle NetBSD mremap, | |
| 1753 | where arguments do not match Linux mremap. | |
| 1754 | ||
| 1755 | 2013-08-26 Paulo Andrade <pcpa@gnu.org> | |
| 1756 | ||
| 1757 | * lib/jit_ppc.c: Correct C sequence point problem miscalculating | |
| 1758 | the actual function address in a function descriptor. Problem | |
| 1759 | happens with gcc 4.8.1 at least. | |
| 1760 | ||
| 1761 | 2013-08-11 Paulo Andrade <pcpa@gnu.org> | |
| 1762 | ||
| 1763 | * lib/jit_s390x-cpu.c: Correct code checking if immediate | |
| 1764 | fits instruction, but using the negated value. | |
| 1765 | ||
| 1766 | 2013-07-28 Paulo Andrade <pcpa@gnu.org> | |
| 1767 | ||
| 1768 | * include/lightning/jit_s390x.h, lib/jit_s390x-cpu.c, | |
| 1769 | lib/jit_s390x-fpu.c, lib/jit_s390x.c: New files | |
| 1770 | implementing the new s390x port. | |
| 1771 | ||
| 1772 | * configure.ac, include/lightning.h, | |
| 1773 | include/lightning/Makefile.am, | |
| 1774 | include/lightning/jit_private.h, | |
| 1775 | lib/Makefile.am, lib/jit_disasm.c, lib/lightning.c: | |
| 1776 | Minor adaptation for the new s390x backend. | |
| 1777 | ||
| 1778 | * check/float.tst: Update for the s390x result of | |
| 1779 | truncating +Inf to integer. | |
| 1780 | ||
| 1781 | * check/qalu_mul.tst: Add extra test cases to better test | |
| 1782 | high word of signed multiplication as the result is | |
| 1783 | adjust from unsigned multiplication on s390x. | |
| 1784 | ||
| 1785 | 2013-07-28 Paulo Andrade <pcpa@gnu.org> | |
| 1786 | ||
| 1787 | * check/lightning.c: Do not assume casting a double NaN or | |
| 1788 | Inf to float will produce the expected float NaN or Inf. | |
| 1789 | This is not true at least under s390x. | |
| 1790 | ||
| 1791 | 2013-07-28 Paulo Andrade <pcpa@gnu.org> | |
| 1792 | ||
| 1793 | * check/check.arm.sh, check/check.sh, check/check.swf.sh, | |
| 1794 | check/check.x87.sh: Properly check test programs output, | |
| 1795 | not just rely on the test program self testing the results | |
| 1796 | and not crashing. | |
| 1797 | ||
| 1798 | 2013-07-28 Paulo Andrade <pcpa@gnu.org> | |
| 1799 | ||
| 1800 | * lib/jit_aarch64.c: Remove unused macros left from cut&paste | |
| 1801 | of jit_arm.c. | |
| 1802 | ||
| 1803 | 2013-07-16 Paulo Andrade <pcpa@gnu.org> | |
| 1804 | ||
| 1805 | * include/lightning/jit_aarch64.h, lib/jit_aarch64-cpu.c, | |
| 1806 | lib/jit_aarch64-fpu.c, lib/jit_aarch64.c: New files | |
| 1807 | implementing the new aarch64 port, as a new architecture, | |
| 1808 | not as an expansion of the existing armv[4-7] port. | |
| 1809 | ||
| 1810 | * check/lightning.c: Add aarch64 support and a small | |
| 1811 | change to recognize character constants as immediate | |
| 1812 | values. | |
| 1813 | ||
| 1814 | * check/float.tst: Add aarch64 preprocessor conditionals | |
| 1815 | to select proper expected value when converting [+-]Inf | |
| 1816 | and NaN to integer. | |
| 1817 | ||
| 1818 | * include/lightning/jit_arm.h, lib/jit_arm.c: Minor changes | |
| 1819 | to better match the new aarch64 files. | |
| 1820 | ||
| 1821 | * configure.ac, include/lightning.h, | |
| 1822 | include/lightning/Makefile.am, include/lightning/jit_private.h, | |
| 1823 | lib/Makefile.am, lib/lightning.c: Minor adjustments | |
| 1824 | for the aarch64 port. | |
| 1825 | ||
| 1826 | 2013-07-08 Paulo Andrade <pcpa@gnu.org> | |
| 1827 | ||
| 1828 | * NEWS, THANKS, configure.ac, doc/version.texi: Update for | |
| 1829 | the 1.99a second alpha release. | |
| 1830 | ||
| 1831 | 2013-06-25 Paulo Andrade <pcpa@gnu.org> | |
| 1832 | ||
| 1833 | * lib/jit_mips.c: Correct cut&paste error that caused wrong | |
| 1834 | stack offset calculation for double arguments in stack in | |
| 1835 | the o32 abi. | |
| 1836 | Correct typo in the __LITTLE_ENDIAN macro name, that came | |
| 1837 | from cut&paste error in the original typo in lib/jit_ppc.c. | |
| 1838 | ||
| 1839 | * lib/jit_ia64.c, lib/jit_ppc.c: Correct typo in the | |
| 1840 | __LITTLE_ENDIAN macro name. | |
| 1841 | ||
| 1842 | 2013-06-22 Paulo Andrade <pcpa@gnu.org> | |
| 1843 | ||
| 1844 | * check/lightning.c, configure.ac, include/lightning.h, | |
| 1845 | lib/lightning.c: Add tests and quirks to build/detect | |
| 1846 | and/or work on Irix. | |
| 1847 | ||
| 1848 | * include/lightning/jit_mips.h, lib/jit_mips-cpu.c, | |
| 1849 | lib/jit_mips-fpu.c, lib/jit_mips.c: Adapt code to run | |
| 1850 | in big endian mips, using the n32 abi. | |
| 1851 | ||
| 1852 | 2013-06-18 Paulo Andrade <pcpa@gnu.org> | |
| 1853 | ||
| 1854 | * include/lightning.h: Minor extra preprocessor testing | |
| 1855 | to "detect" byte order on x86 solaris, that now builds | |
| 1856 | and pass all test cases. | |
| 1857 | ||
| 1858 | 2013-06-18 Paulo Andrade <pcpa@gnu.org> | |
| 1859 | ||
| 1860 | * lib/jit_sparc-cpu.c: Correct compiler warning of value | |
| 1861 | used before assignment. The usage is bogus as the api | |
| 1862 | requires always patching jumps, but the random value used | |
| 1863 | could cause an assertion due to invalid displacement. | |
| 1864 | ||
| 1865 | * lib/jit_sparc.c: Always load and store double arguments | |
| 1866 | in stack as 2 float loads or stores, for safety, as unaligned | |
| 1867 | access is not allowed in Sparc Solaris. | |
| 1868 | ||
| 1869 | 2013-06-14 Paulo Andrade <pcpa@gnu.org> | |
| 1870 | ||
| 1871 | * configure.ac: Force -mlp64 to CFLAGS on HP-UX ia64 port. | |
| 1872 | It is the only supported mode, and expects gcc as C compiler. | |
| 1873 | ||
| 1874 | * include/lightning.h, lib/jit_ia64-cpu.c, lib/jit_ia64.c: | |
| 1875 | Correct ia64 port to work on HP-UX that runs it in big endian | |
| 1876 | mode. | |
| 1877 | ||
| 1878 | 2013-06-10 Paulo Andrade <pcpa@gnu.org> | |
| 1879 | ||
| 1880 | * lib/jit_hppa.c: Sanitize the cache synchronization inline | |
| 1881 | assembly code that was doing twice the work and redundantly | |
| 1882 | flushing the end address every loop iteration. | |
| 1883 | ||
| 1884 | 2013-06-09 Paulo Andrade <pcpa@gnu.org> | |
| 1885 | ||
| 1886 | * configure.ac, check/Makefile.am, doc/Makefile.am: Do not | |
| 1887 | explicitly link to -ldl, but instead autodetect the library | |
| 1888 | with dlopen, dlsym, etc. | |
| 1889 | ||
| 1890 | * check/lightning.c: Add workaround to apparently buggy | |
| 1891 | getopt in HP-UX that sets optind to the wrong index, and | |
| 1892 | use RTLD_NEXT on HP-UX instead of RTLD_DEFAULT to dlsym | |
| 1893 | global symbols. | |
| 1894 | ||
| 1895 | * include/lightning.h: Rework definitions of wordsize and | |
| 1896 | byte order to detect proper values on HP-UX. | |
| 1897 | ||
| 1898 | * lib/lightning.c: Minor correction to use MAP_ANONYMOUS | |
| 1899 | instead of MAP_ANON on HP-UX. | |
| 1900 | ||
| 1901 | * lib/jit_hppa.c: Float arguments must be passed on integer | |
| 1902 | registers on HP-UX, not only for varargs functions. | |
| 1903 | Add code to properly clear instruction cache. This was | |
| 1904 | not required on Debian hppa port, but may have been working | |
| 1905 | by accident. | |
| 1906 | ||
| 1907 | * lib/jit_hppa-cpu.c: Follow pattern of HP-UX binaries and | |
| 1908 | use bve,n instead of bv,n to return from functions. | |
| 1909 | ||
| 1910 | * lib/jit_hppa-fpu.c: For some reason "fst? frX,rX,(rY)" did | |
| 1911 | not work on the tested computer (HP-UX B.11.23 U 9000/785 HP-UX) | |
| 1912 | so the code was changed, at first for __hpux only to add the | |
| 1913 | base and offset register and use the instruction with an | |
| 1914 | immediate (zero) offset. | |
| 1915 | ||
| 1916 | 2013-06-07 Paulo Andrade <pcpa@gnu.org> | |
| 1917 | ||
| 1918 | * check/lightning.c, lib/jit_disasm.c, lib/jit_ppc-cpu.c, | |
| 1919 | lib/jit_ppc-fpu.c, lib/jit_ppc.c, include/lightning.h, | |
| 1920 | include/lightning/jit_ppc.h, include/lightning/jit_private.h: | |
| 1921 | Adapt code to work on 32 bit AIX ppc using gcc. Most changes | |
| 1922 | are basically to adapt the elf64 logic to 32 bit, as it does | |
| 1923 | not use the same convention of 32 bit Darwin ppc. | |
| 1924 | ||
| 1925 | * check/stack.tst: Add a fake memcpy function to the test | |
| 1926 | case if running under AIX, as it is not available to dlsym. | |
| 1927 | ||
| 1928 | * configure.ac: Check for getopt.h header, not available in | |
| 1929 | AIX. | |
| 1930 | ||
| 1931 | 2013-06-01 Paulo Andrade <pcpa@gnu.org> | |
| 1932 | ||
| 1933 | * include/lightning/jit_hppa.h, lib/jit_hppa-cpu.c, | |
| 1934 | lib/jit_hppa-fpu.c, lib/jit_hppa.c: New files implementing | |
| 1935 | the hppa port. Built on Debian Linux PA-RISC 2.0, 32 bit. | |
| 1936 | ||
| 1937 | * check/float.tst: Add preprocessor for hppa expected | |
| 1938 | values when converting NaN and +-Inf to an integer. | |
| 1939 | ||
| 1940 | * check/ldst.inc: Ensure double load/store tests use an | |
| 1941 | 8 byte aligned address by default. | |
| 1942 | ||
| 1943 | * lib/lightning.c: Correct a bug found during tests in | |
| 1944 | the new port, where qmul* and qdiv* were not properly | |
| 1945 | setting one of the result registers as modified in the | |
| 1946 | function, what would be a problem if the only "write" | |
| 1947 | usage were the qmul* or qdiv*. | |
| 1948 | ||
| 1949 | * check/varargs.tst, check/varargs.ok: Add one extra | |
| 1950 | interleaved integer/double test to validate proper code | |
| 1951 | generation in the extra case. | |
| 1952 | ||
| 1953 | * check/lightning.c, configure.ac, include/lightning.h, | |
| 1954 | include/lightning/Makefile.am, | |
| 1955 | include/lightning/jit_private.h, lib/Makefile.am, | |
| 1956 | lib/jit_disasm.c: Update for the hppa port. | |
| 1957 | ||
| 1958 | 2013-04-27 Paulo Andrade <pcpa@gnu.org> | |
| 1959 | ||
| 1960 | * check/varargs.tst: Correct misplaced .align directive | |
| 1961 | that was causing the double buffer to not be aligned at | |
| 1962 | 8 bytes. | |
| 1963 | * lib/jit_ia64-cpu.c: | |
| 1964 | Properly implement abi for excess arguments passed on | |
| 1965 | stack. | |
| 1966 | Simplify load/store with immediate displacement argument | |
| 1967 | with zero value. | |
| 1968 | Simplify some calls to "subi" changing to "addi" with | |
| 1969 | a negative argument. | |
| 1970 | Remove some #if 0'ed code, that could be useful in | |
| 1971 | special conditions, but the most useful one would be | |
| 1972 | to "optimize" "static" jit functions, but for the sake | |
| 1973 | of simplicity, jit functions are implemented in a way | |
| 1974 | that can be passed back to C code as C function pointers. | |
| 1975 | Add an attribute to prototypes of several unused functions. | |
| 1976 | These functions are defined for the sake of implementing all | |
| 1977 | Itanium documented instructions, but a significant amount of | |
| 1978 | them is not used by lightning. | |
| 1979 | * lib/jit_ia64-fpu.c: Simplify load/store with zero immediate | |
| 1980 | displacement and add unused attribute for functions not used | |
| 1981 | by lightning, but required to provide macros implementing all | |
| 1982 | Itanium documented instructions. | |
| 1983 | * lib/jit_ia64.c: Update for the properly implemented abi | |
| 1984 | for stack arguments. | |
| 1985 | * lib/lightning.c: Mark an unused function as such. | |
| 1986 | ||
| 1987 | 2013-04-27 Paulo Andrade <pcpa@gnu.org> | |
| 1988 | ||
| 1989 | lib/jit_ia64-cpu.c: | |
| 1990 | Correct immediate range check of integer comparisons when | |
| 1991 | inverting arguments. | |
| 1992 | Correct gei_u that was not decrementing immediate when | |
| 1993 | inverting arguments. | |
| 1994 | Correct b?add* and b?sub* that were not properly updating | |
| 1995 | the result register. | |
| 1996 | ||
| 1997 | 2013-04-27 Paulo Andrade <pcpa@gnu.org> | |
| 1998 | ||
| 1999 | * lib/jit_ia64-cpu.c: Correct wrong mapping of 2 instructions | |
| 2000 | in "M-, stop, M-, stop" translation, that was ignoring the | |
| 2001 | last stop (implemented as a nop I- stop). | |
| 2002 | ||
| 2003 | * lib/jit_ia64-fpu.c: Properly implement fnorm.s and fnorm.d, | |
| 2004 | as well as the proper integer to float or double conversion. | |
| 2005 | ||
| 2006 | 2013-04-27 Paulo Andrade <pcpa@gnu.org> | |
| 2007 | ||
| 2008 | * lib/jit_ia64-cpu.c: Correct bogus implementation of ldr_T | |
| 2009 | for signed integers, that was using ld1.s, ld2.s and ld4.s. | |
| 2010 | The ".s" stands for speculative load, not sign extend. | |
| 2011 | ||
| 2012 | * lib/jit_ia64-fpu.c: Correct bogus implementation of ldxr_T | |
| 2013 | for float and double. The third (actually, second) argument | |
| 2014 | is indeed added to the base register, but the base register | |
| 2015 | is modified. The actual M7 implementation was already correct, | |
| 2016 | just the ldxr_f and ldxr_d implementation that was kept in | |
| 2017 | a prototype state, misinterpreting what M7 does. | |
| 2018 | ||
| 2019 | 2013-04-27 Paulo Andrade <pcpa@gnu.org> | |
| 2020 | ||
| 2021 | * lib/jit_ia64-cpu.c: Correct X2 pattern matching by preventing | |
| 2022 | it to attempt to require a stop between the L and the X | |
| 2023 | instruction; that is, check the registers and predicates | |
| 2024 | before emitting the L instruction, not after. | |
| 2025 | ||
| 2026 | * lib/jit_ia64-fpu.c: Slightly simplify and correct | |
| 2027 | divr_f and divrd_d implementation. | |
| 2028 | ||
| 2029 | * check/lightning.c: Add __ia64__ preprocessor define | |
| 519a9ea1 | 2030 | on Itanium. |
| 4a71579b PC |
2031 | |
| 2032 | * check/alu.inc, check/clobber.tst, check/float.tst: Define | |
| 2033 | several macros conditionally to __ia64__. This is required | |
| 2034 | because __ia64__ jit generation can use way too many memory, | |
| 2035 | due to not implementing instruction reordering to avoid | |
| 2036 | as much as possible "stops", what causes way too many nops | |
| 2037 | to be generated, as well as the fact that division and | |
| 2038 | remainder requires function calls, and float division | |
| 2039 | requires significant code to implement. | |
| 2040 | ||
| 2041 | 2013-04-27 Paulo Andrade <pcpa@gnu.org> | |
| 2042 | ||
| 2043 | * include/lightning.h: Add new backend specific movr_w_d, | |
| 2044 | movr_d_w and movi_d_w codes as helpers to ia64 varargs | |
| 2045 | functions arguments. | |
| 2046 | ||
| 2047 | * lib/jit_ia64-cpu.c: | |
| 2048 | Correct wrong encoding of A5 small integers. | |
| 2049 | Correct define of "mux" instruction modifiers. | |
| 2050 | Correct ordering of arguments and predicates of cmp_xy | |
| 2051 | implementation with immediate arguments; like most other | |
| 2052 | codes with an immediate, the immediate is the second, not | |
| 2053 | the third argument. | |
| 2054 | ||
| 2055 | * lib/jit_ia64-fpu.c: Actual implementation of the code | |
| 2056 | to move to/from gpr to/from fpr, to implement varargs abi. | |
| 2057 | ||
| 2058 | * lib/jit_ia64.c: Make fpr argument registers not allocatable | |
| 2059 | as temporaries, no need for the extra checks when there are | |
| 2060 | plenty registers. | |
| 2061 | ||
| 2062 | * lib/jit_print.c, lib/lightning.c: Minor updates for the | |
| 2063 | new movr_w_d, movr_d_w and movi_d_w codes. | |
| 2064 | ||
| 2065 | 2013-04-26 Paulo Andrade <pcpa@gnu.org> | |
| 2066 | ||
| 2067 | * lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c: Correct code to | |
| 2068 | also insert a stop to break an instruction group if a | |
| 2069 | register is written more than once in the same group. | |
| 2070 | This may happen if a register is argument and result of | |
| 2071 | some lightning call (not a real instruction). The most | |
| 2072 | common case should be code in the pattern: | |
| 2073 | movl rn=largenum | |
| 2074 | ... | |
| 2075 | mov rn=smallnum | |
| 2076 | where "rn" would end up holding "largenum". | |
| 2077 | But the problem possibly could happen in other circumstances. | |
| 2078 | ||
| 2079 | 2013-04-26 Paulo Andrade <pcpa@gnu.org> | |
| 2080 | ||
| 2081 | * include/lightning/jit_ia64.h, lib/jit_ia64-cpu.c, | |
| 2082 | lib/jit_ia64-fpu.c, lib/jit_ia64.c: | |
| 2083 | Relocate JIT_Rn registers to the local registers, as, like | |
| 2084 | float registers, div/rem and sqrt are implemented as function | |
| 2085 | calls, and may overwrite non saved scratch registers. | |
| 2086 | Change patch_at to receive a jit_code_t instead of a | |
| 2087 | jit_node_t, so that it is easier to "inline" patches when | |
| 2088 | some instruction requires complex code to implement, e.g. | |
| 2089 | uneq and ltgt. | |
| 2090 | Correct arguments to FMA and FMA like instructions that, | |
| 2091 | due to a cut&paste error were passing the wrong argument | |
| 2092 | to the related F- implementation function. | |
| 2093 | Rewrite ltgt to return the proper result if one (or both) | |
| 2094 | of the arguments is unordered. | |
| 2095 | ||
| 2096 | 2013-04-26 Paulo Andrade <pcpa@gnu.org> | |
| 2097 | ||
| 2098 | * include/lightning/jit_ia64.h, include/lightning/jit_private.h, | |
| 2099 | lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c, lib/jit_ia64.c, | |
| 2100 | lib/lightning.c: Rework code to detect need of a "stop" to | |
| 2101 | also handle predicates, as if a predicate is written, it | |
| 2102 | cannot be read in the same instruction group. | |
| 2103 | Use a single jit_regset_t variable for all registers when | |
| 2104 | checking need for a stop (increment value by 128 for | |
| 2105 | float registers). | |
| 2106 | Correct wrong "subi" implementation, as the code executed | |
| 2107 | is r0=im-r1, not r0=r1-im. | |
| 2108 | Use standard lightning 6 fpr registers, and rework to | |
| 2109 | use callee save float registers, that may be spill/reloaded | |
| 2110 | in prolog/epilog. This is required because some jit | |
| 2111 | instructions implementations need to call functions; currently | |
| 2112 | integer div/mod and float sqrt, what may change the value of | |
| 2113 | scratch float registers. | |
| 2114 | Rework point of "sync" of branches that need to return a | |
| 2115 | patch'able address, because the need for a "stop" before a | |
| 2116 | predicate read causes all branches to be the instruction | |
| 2117 | in slot 0, as there is no template to "stop" and branch | |
| 2118 | in the same instruction "bundle". | |
| 2119 | ||
| 2120 | 2013-04-25 Paulo Andrade <pcpa@gnu.org> | |
| 2121 | ||
| 2122 | * include/lightning/jit_ia64.h, lib/jit_ia64-cpu.c, | |
| 2123 | lib/jit_ia64-fpu.c, lib/jit_ia64.c: New files implementing | |
| 2124 | the basic infrastructure of an Itanium port. The code | |
| 2125 | compiles and can generate jit for basic hello world like | |
| 2126 | functions. | |
| 2127 | ||
| 2128 | * check/lightning.c, configure.ac, include/lightning.h, | |
| 2129 | include/lightning/Makefile.am, include/lightning/jit_private.h, | |
| 2130 | lib/Makefile.am, lib/lightning.c: Update for the Itanium | |
| 2131 | port. | |
| 2132 | ||
| 2133 | * lib/jit_mips-cpu.c, lib/jit_mips.c: Correct typo and | |
| 2134 | make the jit_carry register local to the jit_state_t. | |
| 2135 | This matches code reviewed in the Itanium port, that | |
| 2136 | should use the same base logic to handle carry/borrow. | |
| 2137 | ||
| 2138 | 2013-04-10 Paulo Andrade <pcpa@gnu.org> | |
| 2139 | ||
| 2140 | * include/lightning/jit_private.h, lib/jit_arm.c, | |
| 2141 | lib/jit_mips-cpu.c, lib/jit_mips.c, lib/jit_ppc-cpu.c, | |
| 2142 | lib/jit_ppc.c, lib/jit_print.c, lib/jit_sparc-cpu.c, | |
| 2143 | lib/jit_sparc.c, lib/jit_x86-cpu.c, lib/jit_x86.c, | |
| 2144 | lib/lightning.c: Change all jit_regset macros to take | |
| 2145 | a pointer argument, to avoid structure copies when | |
| 2146 | adding a port to an architecture with more than 64 | |
| 2147 | registers. | |
| 2148 | ||
| 2149 | 2013-04-08 Paulo Andrade <pcpa@gnu.org> | |
| 2150 | ||
| 2151 | * lib/jit_arm.c, lib/jit_ppc.c: Do not rely on __clear_cache | |
| 2152 | aligning to the next page boundary the end argument. It may | |
| 2153 | actually truncate it. | |
| 2154 | ||
| 2155 | 2013-03-29 Paulo Andrade <pcpa@gnu.org> | |
| 2156 | ||
| 2157 | * include/lightning/jit_private.h, lib/jit_arm.c, lib/jit_memory.c, | |
| 2158 | lib/jit_mips.c, lib/jit_ppc.c, lib/jit_sparc.c, lib/jit_x86.c, | |
| 2159 | lib/lightning.c: Do not start over jit generation if can grow | |
| 2160 | the code buffer with mremap without moving the base pointer. | |
| 2161 | ||
| 2162 | 2013-03-29 Paulo Andrade <pcpa@gnu.org> | |
| 2163 | ||
| 2164 | * lib/jit_memory.c: Implement a simple memory allocation wrapper | |
| 2165 | to allow overriding calls to malloc/calloc/realloc/free, as well | |
| 2166 | as ensuring all memory containing pointers is zero or points to | |
| 2167 | allocated memory. | |
| 2168 | ||
| 2169 | * include/lightning.h, include/lightning/jit_private.h: Definitions | |
| 2170 | for the memory allocation wrapper. | |
| 2171 | ||
| 2172 | * lib/Makefile.am: Update for new jit_memory.c file. | |
| 2173 | ||
| 2174 | * lib/jit_arm.c, lib/jit_disasm.c, lib/jit_mips.c, lib/jit_note.c, | |
| 2175 | lib/jit_ppc.c, lib/jit_sparc.c, lib/jit_x86.c, lib/lightning.c: | |
| 2176 | Use the new memory allocation wrapper code. | |
| 2177 | ||
| 2178 | 2013-03-22 Paulo Andrade <pcpa@gnu.org> | |
| 2179 | ||
| 2180 | * configure.ac, include/lightning/jit_private.h, lib/lightning.c: | |
| 2181 | Remove dependency on gmp. Only a simple bitmap was required, and | |
| 2182 | that was not enough reason to force linking to gmp and possible | |
| 2183 | complications caused by it. | |
| 2184 | ||
| 2185 | 2013-03-10 Paulo Andrade <pcpa@gnu.org> | |
| 2186 | ||
| 2187 | * include/lightning.h: Add check for __powerpc__ defined | |
| 2188 | in Linux, while Darwin defines __ppc__. | |
| 2189 | ||
| 2190 | * include/lightning/jit_ppc.h: Adjust register definitions | |
| 2191 | for Darwin 32 bit and Linux 64 bit ppc usage and/or ABI. | |
| 2192 | ||
| 2193 | * include/lightning/jit_private.h: Add proper check for | |
| 2194 | Linux __powerpc__ and an data definition for an workaround | |
| 2195 | to properly handle code that starts with a jump to a "main" | |
| 2196 | label. | |
| 2197 | ||
| 2198 | * lib/jit_disasm.c: Add extra disassembler initialization | |
| 2199 | for __powerpc64__. | |
| 2200 | ||
| 2201 | * lib/jit_ppc-cpu.c: Add extra macros and functions, and | |
| 2202 | correct/adapt previous ones to handle powerpc64. | |
| 2203 | ||
| 2204 | * lib/jit_ppc-fpu.c: Adapt for 64 bit wordsize. Basically | |
| 2205 | add conversion from/to int32/int64 and proper handling of | |
| 2206 | load/store offsets too large for 32 bit. | |
| 2207 | ||
| 2208 | * lib/jit_ppc.c: Add calls to 64 bit codes and adaptation | |
| 2209 | for the PowerPC 64 bit Linux ABI. | |
| 2210 | ||
| 2211 | * lib/jit_arm.c, lib/jit_mips.c, lib/jit_sparc, lib/jit_x86.c, | |
| 2212 | lib/lightning.c: Correct off by one error when restarting jit | |
| 2213 | of a function due to finding too late that needs to spill/reload | |
| 2214 | some register. Problem was found by accident on a very special | |
| 2215 | condition during PowerPC 64 code adaptation. | |
| 2216 | ||
| 2217 | 2013-03-08 Paulo Andrade <pcpa@gnu.org> | |
| 2218 | ||
| 2219 | * check/lightning.c: Add missing ppc preprocessor definition. | |
| 2220 | ||
| 2221 | 2013-03-06 Paulo Andrade <pcpa@gnu.org> | |
| 2222 | ||
| 2223 | * check/float.tst: Comment out the int to negative infinity | |
| 2224 | test in mips for the moment because not all Loongson agrees | |
| 2225 | on the result. | |
| 2226 | ||
| 2227 | * lib/jit_disasm.c: Add a test instead of an assertion | |
| 2228 | when loading symbols for disassembly due to a failure with | |
| 2229 | a simple binutils build in Debian mipsel64. | |
| 2230 | ||
| 2231 | 2013-03-06 Paulo Andrade <pcpa@gnu.org> | |
| 2232 | ||
| 2233 | * include/lightning/jit_private.h, lib/jit_arm-cpu.c, | |
| 2234 | lib/jit_arm.c, lib/jit_disasm.c, lib/jit_mips-cpu.c, | |
| 2235 | lib/jit_mips.c, lib/jit_note.c, lib/jit_ppc-cpu.c, | |
| 2236 | lib/jit_ppc.c, lib/jit_print.c, lib/jit_sparc-cpu.c, | |
| 2237 | lib/jit_sparc.c, lib/jit_x86-cpu.c, lib/jit_x86.c, | |
| 2238 | lib/lightning.c: Add an extra structure for data storage | |
| 2239 | during jit generation, and release it after generating | |
| 2240 | jit, to reduce a bit memory usage, and also to make it | |
| 2241 | easier to understand what data is available during | |
| 2242 | jit runtime. | |
| 2243 | ||
| 2244 | 2013-03-06 Paulo Andrade <pcpa@gnu.org> | |
| 2245 | ||
| 2246 | * lib/lightning.c: Make data and code buffer readonly. | |
| 2247 | ||
| 2248 | 2013-02-20 Paulo Andrade <pcpa@gnu.org> | |
| 2249 | ||
| 2250 | * doc/body.texi: Fool proof validate the examples of what | |
| 2251 | an assembly-language programmer would write and correct the | |
| 2252 | wrong sparc example. | |
| 2253 | ||
| 2254 | 2013-02-19 Paulo Andrade <pcpa@gnu.org> | |
| 2255 | ||
| 2256 | * doc/body.texi: Add back the SPARC code generation example. | |
| 2257 | ||
| 2258 | 2013-02-19 Paulo Andrade <pcpa@gnu.org> | |
| 2259 | ||
| 2260 | * check/lightning.c: Remove state flag to work with partial | |
| 2261 | sparc port, by just disassembling if there was incomplete | |
| 2262 | code generation. | |
| 2263 | ||
| 2264 | * jit_sparc-cpu.c: Correct wrong range check for immediate | |
| 2265 | integer constants (off by one bit shift). | |
| 2266 | Correct macro implementing equivalent "rd %y, rd" assembly. | |
| 2267 | Implement qmul* and qdiv*. | |
| 2268 | ||
| 2269 | * jit_sparc.c: Update for qmul* and qdiv* and remove logic | |
| 2270 | to handle incomplete code generation during sparc port. | |
| 2271 | ||
| 2272 | 2013-02-18 Paulo Andrade <pcpa@gnu.org> | |
| 2273 | ||
| 2274 | * check/float.tst: Add sparc to list of known NaN and +-Inf | |
| 2275 | to integer conversion. | |
| 2276 | ||
| 2277 | * check/lightning.c: Define __sparc__ to preprocessor in | |
| 2278 | the sparc backend. | |
| 2279 | ||
| 2280 | * include/lightning/jit_private.h: Correct wrong definition | |
| 2281 | of emit_stxi_d, that has lived for a long time, but would | |
| 2282 | cause problems whenever needing to spill/reload a float | |
| 2283 | register. | |
| 2284 | ||
| 2285 | * include/lightning/jit_sparc.h: Can only use %g2,%g3,%g4 | |
| 2286 | for scratch variables, as other "global" registers are | |
| 2287 | reserved for the system, e.g. libc. | |
| 2288 | Reorder float register naming to make it easier to | |
| 2289 | access odd float registers, so that generating code for | |
| 2290 | pusharg and getarg is easier for the IR. | |
| 2291 | ||
| 2292 | * lib/jit_mips-cpu.c, lib/jit_ppc-cpu.c: Update to match | |
| 2293 | new code in jit_sparc-cpu.c. It must call jit_get_reg | |
| 2294 | with jit_class_nospill if using the register to move | |
| 2295 | an unconditional branch address to it, as the reload | |
| 2296 | will not happen (actually could happen in the delay | |
| 2297 | slot...) | |
| 2298 | ||
| 2299 | * lib/jit_sparc-cpu.c: Correct wrong macro definition for | |
| 2300 | ldxr_s. | |
| 2301 | Properly implement div* and implement rem. Div* needs | |
| 2302 | to use the y register, and rem* needs to be synthesized. | |
| 2303 | Correct b?sub* macro definitions. | |
| 2304 | ||
| 2305 | * lib/jit_sparc-fpu.c: Correct reversed float to/from double | |
| 2306 | conversion. | |
| 2307 | Correct wrong jit_get_reg call asking for a gpr and then | |
| 2308 | using the fpr with that number. | |
| 2309 | Correct wrong branch displacement computation for | |
| 2310 | conditional branches. | |
| 2311 | ||
| 2312 | * lib/jit_sparc.c: Correct getarg_d and pushargi_d implementation. | |
| 2313 | Add rem* entries to the switch converting IR to machine code. | |
| 2314 | ||
| 2315 | * lib/lightning.c: Correct a problem detected when adding | |
| 2316 | the jit_class_nospill flag to jit_get_reg, that was caused | |
| 2317 | when having a branch to an "epilog" node, what would cause | |
| 2318 | the code to think all registers in unknown state were live, | |
| 2319 | while in truth, all registers in unknown state in the | |
| 2320 | "just after return" point are actually dead. | |
| 2321 | ||
| 2322 | 2013-02-17 Paulo Andrade <pcpa@gnu.org> | |
| 2323 | ||
| 2324 | * include/lightning/jit_sparc.h, lib/jit_sparc-cpu.c, | |
| 2325 | lib/jit_sparc-fpu.c, lib/jit_sparc.c: New files implementing | |
| 2326 | the basic framework of the sparc port. | |
| 2327 | ||
| 2328 | * configure.ac, include/lightning.h, include/lightning/Makefile.am, | |
| 2329 | include/lightning/jit_private.h, lib/jit_disasm.c: Update | |
| 2330 | for the sparc port framework. | |
| 2331 | ||
| 2332 | * lib/jit_mips.c: Correct reversed retr/reti logic. | |
| 2333 | ||
| 2334 | * lib/jit_ppc.c: Correct misspelled __LITTLE_ENDIAN. | |
| 2335 | ||
| 2336 | * lib/lightning.c: Always do byte hashing in hash_data, because | |
| 2337 | the logic to "compress" strings causes large pointers to not | |
| 2338 | be guaranteed aligned at 4 byte boundaries. | |
| 2339 | Update for the sparc port framework. | |
| 2340 | ||
| 2341 | 2013-02-11 Paulo Andrade <pcpa@gnu.org> | |
| 2342 | ||
| 2343 | * lib/jit_arm.c: Correct jit_pushargi_f in the arm hardfp abi. | |
| 2344 | Most of the logic uses even numbered register numbers, so that | |
| 2345 | a float and a double can be used in the same register, but | |
| 2346 | the abi requires packing the float arguments, so jit_pushargi_f | |
| 2347 | needs to allocate a temporary register to modify only the | |
| 2348 | proper register argument (or be very smart to push two | |
| 2349 | immediate arguments if applicable). | |
| 2350 | ||
| 2351 | 2013-02-11 Paulo Andrade <pcpa@gnu.org> | |
| 2352 | ||
| 2353 | * include/lightning.h, lib/lightning.c: Implement the new | |
| 2354 | jit_clear_state and jit_destroy_state calls. jit_clear_state | |
| 2355 | releases all memory not required during jit_execution; that | |
| 2356 | is, leaves only the mmap'ed data and code buffers allocated. | |
| 2357 | jit_destroy_state releases the mmap'ed buffers as well as | |
| 2358 | the jit_state_t object itself, that holds pointers to the | |
| 2359 | code and data buffers, as well as annotation pointers (for | |
| 2360 | disassembly or backtrace) in the data buffer. | |
| 2361 | ||
| 2362 | * lib/jit_note.c: Correct invalid vector offset access. | |
| 2363 | ||
| 2364 | * check/ccall.c, check/lightning.c, doc/ifib.c, doc/incr.c, | |
| 2365 | doc/printf.c, doc/rfib.c, doc/rpn.c: Use the new jit_clear_state | |
| 2366 | and jit_destroy_state calls, to demonstrate the new code to | |
| 2367 | release all jit memory. | |
| 2368 | ||
| 2369 | * doc/body.texi: Add basic documentation and usage description | |
| 2370 | of jit_clear_state and jit_destroy_state. | |
| 2371 | ||
| 2372 | 2013-02-11 Paulo Andrade <pcpa@gnu.org> | |
| 2373 | ||
| 2374 | * include/lightning/jit_private.h, lib/jit_note.c, lib/lightning.c: | |
| 2375 | Store all annotation information in the mmap'ed area reserved for | |
| 2376 | read only data. This adds code to not allocate memory for jit_note_t | |
| 2377 | objects, and to relocate jit_line_t objects and its contents after | |
| 2378 | calculating annotation information. The jit_line_t objects are | |
| 2379 | relocated because it is not possible to always calculate before | |
| 2380 | hand data layout because note information may be extended or | |
| 2381 | redundant entries removed, as well as allowed to be added in | |
| 2382 | non sequential order. | |
| 2383 | A bug was also corrected in _jit_set_note, that was causing it | |
| 2384 | to allocate new jit_line_t objects when not needed. It was still | |
| 2385 | working correctly, but allocating way more memory than required. | |
| 2386 | ||
| 2387 | 2013-02-05 Paulo Andrade <pcpa@gnu.org> | |
| 2388 | ||
| 2389 | *include/lightning.h, lib/lightning.c: Add the new jit_live code | |
| 2390 | to explicitly mark a register as live. It is required to avoid | |
| 2391 | assuming functions always return a value in the gpr and fpr return | |
| 2392 | register, and to avoid the need of some very specialized codes | |
| 2393 | that vary too much from backend to backend, to instruct the | |
| 2394 | optimization code the return register is live. | |
| 2395 | ||
| 2396 | * lib/jit_arm.c, lib/jit_mips.c, lib/jit_ppc.c, lib/jit_print.c, | |
| 2397 | lib/jit_x86.c: Update for the new jit_live code. | |
| 2398 | ||
| 2399 | * check/ret.ok, check/ret.tst: New files implementing a simple | |
| 2400 | test case that would previously fail at least in ix86/x86_64. | |
| 2401 | ||
| 2402 | * check/Makefile.am: Update for new "ret" test case. | |
| 2403 | ||
| 2404 | 2013-02-05 Paulo Andrade <pcpa@gnu.org> | |
| 2405 | ||
| 2406 | * lib/jit_ppc-cpu.c, lib/jit_ppc.c: Validate and correct | |
| 2407 | problems in the qmul and qdiv ppc implementation. | |
| 2408 | ||
| 2409 | 2013-02-04 Paulo Andrade <pcpa@gnu.org> | |
| 2410 | ||
| 2411 | * include/lightning.h, include/lightning/jit_private.h, | |
| 2412 | lib/jit_arm-cpu.c, lib/jit_arm.c, lib/jit_mips-cpu.c, | |
| 2413 | lib/jit_mips.c, lib/jit_ppc-cpu.c, lib/jit_ppc.c, | |
| 2414 | lib/jit_x86-cpu.c, lib/jit_x86.c, lib/lightning.c: | |
| 2415 | Implement the new qmul and qdiv instructions that return signed | |
| 2416 | and unsigned lo/hi multiplication result and div/rem division result. | |
| 2417 | These should be useful for jit translation of code that needs to | |
| 2418 | know if a multiplication overflows (no branch opcode added) or if | |
| 2419 | a division is exact (easy check if remainder is zero). | |
| 2420 | ||
| 2421 | * check/lightning.c, lib/jit_print.c, check/Makefile.am, | |
| 2422 | check/all.tst: Update for the new qmul and qdiv instructions. | |
| 2423 | ||
| 2424 | * check/qalu.inc, check/qalu_div.ok, check/qalu_div.tst, | |
| 2425 | check/qalu_mul.ok, check/qalu_mul.tst: New files implementing | |
| 2426 | simple test cases for qmul and qdiv. | |
| 2427 | ||
| 2428 | 2013-01-30 Paulo Andrade <pcpa@gnu.org> | |
| 2429 | ||
| 2430 | * doc/body.texi: Correct "jmpi" description that incorrectly | |
| 2431 | told it was possible to pass any address as jump target. The | |
| 2432 | only way to do that is "movi+jmpr". | |
| 2433 | ||
| 2434 | 2013-01-30 Paulo Andrade <pcpa@gnu.org> | |
| 2435 | ||
| 2436 | * lib/jit_x86-cpu.c: Correct undefined behavior code. | |
| 2437 | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56143 | |
| 2438 | ||
| 2439 | 2013-01-29 Paulo Andrade <pcpa@gnu.org> | |
| 2440 | ||
| 2441 | * configure.ac: Use AC_CONFIG_HEADERS instead of AC_CONFIG_HEADER | |
| 2442 | to have HAVE_CONFIG_H defined with latest aclocal. | |
| 2443 | ||
| 2444 | * include/lightning/jit_private.h, lib/lightning.c: Add new | |
| 2445 | abstraction to use an heuristic to calculate amount of space | |
| 2446 | required for jit generation, and code to reallocate buffer if | |
| 2447 | did miscalculate it. | |
| 2448 | ||
| 2449 | * lib/jit_arm.c, lib/jit_mips.c, lib/jit_ppc.c, lib/jit_x86.c: | |
| 2450 | Update to use new code to estimate and resize of required buffer | |
| 2451 | for jit code. | |
| 2452 | ||
| 2453 | * lib/jit_x86-cpu.c: Minor cosmetic change to avoid adding a | |
| 2454 | non required rex prefix when calling a function pointer stored | |
| 2455 | in a register. | |
| 2456 | ||
| 2457 | 2013-01-24 Paulo Andrade <pcpa@gnu.org> | |
| 2458 | ||
| 2459 | * check/Makefile.am: "make debug" target should pass only | |
| 2460 | the main test tool program as argument for running gdb | |
| 2461 | ||
| 2462 | * configure.ac: Add the --enable-assertions options. | |
| 2463 | ||
| 2464 | * doc/Makefile.am, doc/body.texi, doc/lightning.texi: | |
| 2465 | Major rewrite of the documentation to match the current | |
| 2466 | implementation. | |
| 2467 | ||
| 2468 | * doc/version.texi: Automatic date update. | |
| 2469 | ||
| 2470 | * doc/ifib.c, doc/incr.c, doc/printf.c, doc/rfib.c, doc/rpn.c: | |
| 2471 | Implementation of the documentation examples, that are also | |
| 2472 | compiled during a normal build. | |
| 2473 | ||
| 2474 | * doc/p-lightning.texi, doc/porting.texi, doc/toc.texi, | |
| 2475 | doc/u-lightning.texi, doc/using.texi: These files were | |
| 2476 | renamed in the documentation rewrite, as the documentation | |
| 2477 | was significantly trimmed due to full removal of the porting | |
| 2478 | chapters. Better porting documentation should be added but | |
| 2479 | for the moment it was just removed the documentation not | |
| 2480 | matching the implementation. | |
| 2481 | ||
| 2482 | 2013-01-18 Paulo Andrade <pcpa@gnu.org> | |
| 2483 | ||
| 2484 | * lib/jit_note.c: Correct bounds check and wrong code keeping | |
| 2485 | a pointer that could be changed after a realloc call. | |
| 2486 | ||
| 2487 | 2013-01-18 Paulo Andrade <pcpa@gnu.org> | |
| 2488 | ||
| 2489 | * check/3to2.tst, check/add.tst, check/allocai.tst, check/bp.tst, | |

| 2497 | lib/jit_x86.c, lib/lightning.c: Extend the "jit_note" abstraction | |
| 2498 | with the new "jit_name" call, that receives a string argument, and | |
| 2499 | should usually be called to mark boundaries of functions of code | |
| 2500 | generating jit (that is, it is not expected that the language | |
| 2501 | generating jit map its functions to jit functions). | |
| 2502 | ||
| 2503 | 2013-01-17 Paulo Andrade <pcpa@gnu.org> | |

| 2507 | include/lightning/jit_mips.h, include/lightning/jit_ppc.h, | |
| 2508 | include/lightning/jit_private.h, include/lightning/jit_x86.h: | |
| 2509 | Make JIT_RET, JIT_FRET and JIT_SP private. These should not be | |
| 2510 | used in any operations due to frequently having special | |
| 2511 | constraints (usually JIT_FRET). JIT_FP must be made available | |
| 2512 | because it must be used as the base register to access stack | |
| 2513 | space allocated with jit_allocai. | |
| 2514 | ||
| 2515 | 2013-01-14 Paulo Andrade <pcpa@gnu.org> | |
| 2516 | ||
| 2517 | * include/lightning.h, lib/lightning.c: Add an extra align | |
| 2518 | argument to the jit_data call (that should be made private), | |
| 2519 | so that it should not align strings at 8 bytes. | |
| 2520 | Correct the jit_note call to include the null ending byte | |
| 2521 | when adding label/note names to the "jit data section". | |
| 2522 | ||
| 2523 | 2013-01-11 Paulo Andrade <pcpa@gnu.org> | |
| 2524 | ||
| 2525 | * lib/jit_note.c: New file implementing a simple string+integer | |
| 2526 | annotation, that should be used to map filename and line number | |
| 2527 | to offsets in the generated jit. | |
| 2528 | ||
| 2529 | * include/lightning.h, lib/lightning.c: Update for the new | |
| 2530 | note code. | |
| 2531 | Add an extra mandatory argument to init_jit, that is used | |
| 2532 | as argument to bfd_openr. | |
| 2533 | Change from generic void* to char* the argument to jit_note | |
| 2534 | and add an extra integer argument, to map to filename and | |
| 2535 | line number. | |
| 2536 | ||
| 2537 | * check/ccall.c, check/lightning.c, include/lightning/jit_private.h, | |

| 2540 | new annotation code. | |
| 2541 | ||
| 2542 | * configure.ac, check/Makefile.am: Update to work with latest | |
| 2543 | automake. | |
| 2544 | ||
| 2545 | 2013-01-09 Paulo Andrade <pcpa@gnu.org> | |
| 2546 | ||

| 2548 | lib/jit_mips.c, lib/jit_print.c, lib/jit_x86.c, lib/lightning.c: | |
| 2549 | Remove the jit_code_getarg_{f,d} and jit_code_pusharg{i,r}_{f,d} | |
| 2550 | calls, replacing them with the new, internal only, jit_movr_w_f, | |
| 2551 | jit_mov{r,i}_f_w, jit_movr_ww_d, and jit_mov{i,r}_d_ww, that | |
| 2552 | better describe the operation being done, and allow removing | |
| 2553 | the hackish code to detect special conditions for arm when | |
| 2554 | moving from/to vfp from/to a grp register pair. | |
| 2555 | Rename jit_code_retval_{f,d} to jit_code_x86_retval_{f,d} as | |
| 2556 | it is specific to 32 bit x86, and used to move abi return | |
| 2557 | value in x87 register to a sse register. | |
| 2558 | ||
| 2559 | 2013-01-05 Paulo Andrade <pcpa@gnu.org> | |
| 2560 | ||
| 2561 | * check/cccall.c, check/ccall.ok: New test case to validate | |
| 2562 | interleaved calls from/to C code and jit. | |
| 2563 | ||
| 2564 | * check/Makefile.am: Update for the new ccall test case. | |
| 2565 | ||
| 2566 | * include/lightning.h, lib/lightning.c: Add the new jit_address | |
| 2567 | call that returns the real/final address of a "note" in the | |
| 2568 | generated jit. It requires a jit_node_t as returned by the | |
| 2569 | jit_note call, and is only valid after calling jit_emit. | |
| 2570 | Add an intermediate solution to properly handle arm | |
| 2571 | soft and softfp modes that move a double to an integer register | |
| 2572 | pair. Currently it just adds extra tests for the condition, | |
| 2573 | but the proper solution should be to have extra lightning | |
| 2574 | codes for these conditions, codes which should be only used | |
| 2575 | by the backends that need it, and merged with the existing | |
| 2576 | jit_pusharg*_{f,d}. | |
| 2577 | ||
| 2578 | * include/lightning/jit_private.h: Add new jit_state_t flag | |
| 2579 | to know it finished jit_emit, so that calls to jit_address | |
| 2580 | are valid. | |
| 2581 | ||
| 2582 | * lib/jit_mips.c: Correct abi implementation so that the | |
| 2583 | new ccall test case pass. Major problem was using | |
| 2584 | _jit->function.self.arg{i,f} as boolean values, but that | |
| 2585 | would cause lightning.c:patch_registers() to incorrectly | |
| 2586 | assume only one register was used as argument when calling | |
| 2587 | jit_regarg_p(); _jit->function.self.arg{i,f} must be the | |
| 2588 | number of registers used as arguments (in all backends). | |
| 2589 | ||
| 2590 | * lib/jit_x86.c: Add workaround, by marking %rax as used, | |
| 2591 | to a special condition, when running out of registers and the | |
| 2592 | allocator trying to spill and reload %rax, but %rax was used | |
| 2593 | as a pointer to a function, what would cause the reload to | |
| 2594 | destroy the return value. This condition can be better | |
| 2595 | generalized, but the current solution is good enough. | |
| 2596 | ||
| 2597 | * include/lightning/jit_ppc.h, lib/jit_ppc-cpu.c, lib/jit_ppc.c: | |
| 2598 | Rewrite logic to handle arguments, as the original code was | |
| 2599 | written based on a SysV pdf about the generic powerpc ABI, | |
| 2600 | what did "invent" a new abi for the previous test cases, but | |
| 2601 | failed in the new ccall test in Darwin PPC. Now it properly | |
| 2602 | handles 13 float registers for arguments, as well as proper | |
| 2603 | computation of stack offsets when running out of registers | |
| 2604 | for arguments. | |
| 2605 | ||
| 2606 | 2013-01-02 Paulo Andrade <pcpa@gnu.org> | |
| 2607 | ||
| 2608 | * check/float.tst: Correct test case to match ppc also | |
| 2609 | converting positive infinity to 0x7fffffff. | |
| 2610 | ||
| 2611 | * lib/jit_arm-swf.c: Correct typos with double underscores. | |
| 2612 | ||
| 2613 | * lib/lightning.c: Correct remaining wrong reverse jump logic. | |
| 2614 | ||
| 2615 | 2012-12-29 Paulo Andrade <pcpa@gnu.org> | |
| 2616 | ||
| 2617 | * lib/lightning.c: Correct both, wrong and confusing logic | |
| 2618 | to compute the reverse of a jump. Now it properly matches | |
| 2619 | C semantics for "eq" (==) and "ne" (!=) and correct computation | |
| 2620 | of reverse of "uneq" as "gt". | |
| 2621 | ||
| 2622 | * check/branch.tst: Update "ne" float branch check that | |
| 2623 | previously happened to be wrongly tested with a NaN argument. | |
| 2624 | ||
| 2625 | 2012-12-29 Paulo Andrade <pcpa@gnu.org> | |
| 2626 | ||
| 2627 | * check/float.ok, check/float.tst: New test cases implementing | |
| 2628 | extensive validation of float comparison and branch code | |
| 2629 | generation as well as integer conversion, involving NaN and | |
| 2630 | [+-]Inf. | |
| 2631 | ||
| 2632 | * lib/jit_arm-swf.c, lib/jit_x86-sse.c, lib/jit_x86-x87.c: | |
| 2633 | Correct bugs found by new float test case. | |
| 2634 | ||
| 2635 | * lib/jit_x86.c: Correct cut&paste error added in commit to | |
| 2636 | convert jit_arg* return value to a jit_node_t*, that would | |
| 2637 | cause it to not properly handle double arguments in ix86. | |
| 2638 | ||
| 2639 | * check/Makefile.am: Update for the new test case. | |
| 2640 | ||
| 2641 | 2012-12-28 Paulo Andrade <pcpa@gnu.org> | |
| 2642 | ||
| 2643 | * check/lightning.c, include/lightning.h, lib/jit_arm.c, | |
| 2644 | lib/jit_mips.c, lib/jit_ppc.c, lib/jit_print.c, lib/jit_x86.c, | |
| 2645 | lib/lightning.c: Change return value of jit_arg{,_f,_d} to | |
| 2646 | a jit_node_t* object, that should be used as argument to | |
| 2647 | jit_getarg_{c,uc,s,us,i,ui,l,f,d}. This just requires changing | |
| 2648 | from jit_int32_t to jit_pointer_t (or jit_node_t*) the "handle" | |
| 2649 | for the getarg calls, with the benefit that it makes it easy | |
| 2650 | to implement patching of the stack address of non register | |
| 2651 | arguments, this way allowing to implement variable size stack | |
| 2652 | frames if applicable; useful if there are too many registers and | |
| 2653 | jit functions uses only a few callee save registers. | |
| 2654 | ||
| 2655 | 2012-12-27 Paulo Andrade <pcpa@gnu.org> | |
| 2656 | ||
| 2657 | * lib/jit_arm.c, lib/jit_mips-cpu.c, lib/jit_mips.c: Correct | |
| 2658 | regressions when patching jit_calli for a forward function. | |
| 2659 | ||
| 2660 | * lib/jit_ppc-cpu.c: Correct wrong arguments to ANDI opcode | |
| 2661 | in jit_getarg_u{c,s} implementation. | |
| 2662 | ||
| 2663 | 2012-12-23 Paulo Andrade <pcpa@gnu.org> | |
| 2664 | ||
| 2665 | * check/call.ok, check/call.tst: New test cases to validate | |
| 2666 | simple typed argument and return values in function calls. | |
| 2667 | ||
| 2668 | * check/lightning.c: Properly handle jit_movi of labels for | |
| 2669 | backward and forward code labels. | |
| 2670 | ||
| 2671 | * check/Makefile.am: Update for new test case. | |
| 2672 | ||
| 2673 | 2012-12-23 Paulo Andrade <pcpa@gnu.org> | |
| 2674 | ||
| 2675 | * check/carry.ok, check/carry.tst: New test case to validate | |
| 2676 | carry condition handling. | |
| 2677 | ||
| 2678 | * check/Makefile.am: Update for new test case. | |
| 2679 | ||
| 2680 | 2012-12-22 Paulo Andrade <pcpa@gnu.org> | |
| 2681 | ||
| 2682 | * lib/jit_ppc-cpu.c, lib/jit_ppc.c: Implement logic for | |
| 2683 | jit_htonr for big endian, so that ppc (big endian) pass the | |
| 2684 | new clobber.tst test case. | |
| 2685 | ||
| 2686 | 2012-12-22 Paulo Andrade <pcpa@gnu.org> | |
| 2687 | ||
| 2688 | * lib/jit_arm.c: Correct use of wrong argument offset | |
| 2689 | variable in armv7l or float/double argument for varargs | |
| 2690 | function in armv7hl. | |
| 2691 | Correct jit_getarg* logic in software float mode to | |
| 2692 | match expected behavior in other backends, that is, if | |
| 2693 | a function is not called, it is safe to use a few lightning | |
| 2694 | calls before a next jit_getarg* call, as done in the test | |
| 2695 | case check/stack.tst. The proper solution should be to | |
| 2696 | extend the parser in lib/lightning.c to check if there is | |
| 2697 | some float operation that will call some (libgcc?) function, | |
| 2698 | but software float arm should be a very uncommon backend for | |
| 2699 | lightning, so, just load the already in place arguments | |
| 2700 | saved to stack, assuming the register argument was clobbered | |
| 2701 | (what should not be the case most times...). | |
| 2702 | ||
| 2703 | 2012-12-22 Paulo Andrade <pcpa@gnu.org> | |
| 2704 | ||
| 2705 | * check/clobber.ok, check/clobber.tst: New test case doing | |
| 2706 | extensive validation tests to ensure registers not used in | |
| 2707 | a operation are not clobbered. | |
| 2708 | ||
| 2709 | * check/Makefile.am: Update for new test case. | |
| 2710 | ||
| 2711 | 2012-12-21 Paulo Andrade <pcpa@gnu.org> | |
| 2712 | ||
| 2713 | * lib/lightning.c: Partially rewrite/revert code to compute | |
| 2714 | initial register live state at the start of a basic block. | |
| 2715 | The original logic was corrupted when adding optimizations | |
| 2716 | to do as few computations as possible in jit_update. The | |
| 2717 | reglive field must be always a known set of live registers | |
| 2718 | at the start of a basic block. The value that was incorrect | |
| 2719 | was the regmask field, that must be the set of registers | |
| 2720 | that are in unknown state, because they are not known live, | |
| 2721 | neither set (or possibly not set) in the basic block, and | |
| 2722 | *must* store the state at the start of the basic block. | |
| 2723 | ||
| 2724 | 2012-12-20 Paulo Andrade <pcpa@gnu.org> | |
| 2725 | ||
| 2726 | * include/lightning/jit_ppc.h: Correct mismatch of JIT_F{1,5} | |
| 2727 | with enum codes, that were correct, and returned by jit_f(). | |
| 2728 | ||
| 2729 | * lib/jit_ppc-cpu.c, lib/jit_ppc-fpu.c, lib/jit_ppc.c: Properly | |
| 2730 | implement and better describe values when generating stack | |
| 2731 | frames. | |
| 2732 | ||
| 2733 | 2012-12-18 Paulo Andrade <pcpa@gnu.org> | |
| 2734 | ||
| 2735 | * check/stack.ok, check/stack.tst: New files to test data | |
| 2736 | integrity on a deep chain of stack frames. | |
| 2737 | ||
| 2738 | * lib/jit_arm.c, lib/jit_arm-cpu.c, lib/jit_mips.c, | |
| 2739 | lib/jit_mips-cpu.c, lib/jit_ppc.c, lib/jit_ppc-cpu.c, | |
| 2740 | lib/jit_x86.c, lib/jit_x86-cpu.c: Calculate _jit->function->stack | |
| 2741 | in the emit stage, otherwise it will calculate it wrong if | |
| 2742 | need to jit_allocai space to spill registers. | |
| 2743 | ||
| 2744 | * lib/lightning.c: Correct wrong offset when updating the | |
| 2745 | "current" jit function pointer in the code that may need to | |
| 2746 | allocate stack space to spill registers. | |
| 2747 | ||
| 2748 | * check/lightning.c: Correct off by one data space check. | |
| 2749 | ||
| 2750 | * check/Makefile.am: Update for new test case. | |
| 2751 | ||
| 2752 | 2012-12-17 Paulo Andrade <pcpa@gnu.org> | |
| 2753 | ||
| 2754 | * check/fop_abs.ok, check/fop_abs.tst, check/fop_sqrt.ok, | |
| 2755 | check/fop_sqrt.tst: New files implementing simple test cases | |
| 2756 | for the extra float operations. | |
| 2757 | ||
| 2758 | * check/Makefile.am: Update for new test cases. | |
| 2759 | ||
| 2760 | * check/alu.inc: Add an extra macro to check for unordered | |
| 2761 | equality on tests where it is expected to use NaN as an | |
| 2762 | argument. | |
| 2763 | ||
| 2764 | * check/lightning.c: Minor change for proper/common argument | |
| 2765 | syntax handling ommiting arguments to options. | |
| 2766 | ||
| 2767 | 2012-12-17 Paulo Andrade <pcpa@gnu.org> | |
| 2768 | ||
| 2769 | * check/Makefile.am: Automatically generate pattern list | |
| 2770 | of tests with alternate jit generation options. This should | |
| 2771 | prevent typos and needing to change multiple places after | |
| 2772 | a change. | |
| 2773 | ||
| 2774 | 2012-12-14 Paulo Andrade <pcpa@gnu.org> | |
| 2775 | ||
| 2776 | * check/lightning.c: Remove the ".cpu name value" syntax, | |
| 2777 | as it was not able to do proper changes before the jit | |
| 2778 | internal data structure was initialized. Now it supports | |
| 2779 | several getopt options to force using different jit | |
| 2780 | generation options, effectively replacing the previous | |
| 2781 | syntax. | |
| 2782 | ||
| 2783 | * check/run-test: Add simple extra logic to handle differently | |
| 2784 | named test scripts, used to test things like x87 coprocessor | |
| 2785 | in ix86, and arm instruction set or software float in armv7l. | |
| 2786 | ||
| 2787 | * configure.ac: Add some AC_RUN_IFELSE calls to figure at | |
| 2788 | compile time if can test different code generation options, | |
| 2789 | and update Makefile generation accordingly. | |
| 2790 | ||
| 2791 | * check/Makefile.am, lib/jit_arm.c, lib/jit_x86.c: Update to | |
| 2792 | properly work with the test tool updating the jit_cpu global | |
| 2793 | information. | |
| 2794 | ||
| 2795 | * check/check.arm.sh, check/check.swf.sh, check/check.x87.sh: | |
| 2796 | New wrapper files passing -mthumb=0, mvfp=0 and -mx87=1 to | |
| 2797 | the test tool, if applicable, so that it can validate alternate | |
| 2798 | code generation options on test hosts that support them. | |
| 2799 | ||
| 2800 | 2012-12-14 Paulo Andrade <pcpa@gnu.org> | |
| 2801 | ||
| 2802 | * lib/jit_x86-x87.c, lib/jit_x86.c: Correct test cases in ix86 | |
| 2803 | when using the x87 coprocessor instead of sse2+. | |
| 2804 | ||
| 2805 | 2012-12-14 Paulo Andrade <pcpa@gnu.org> | |
| 2806 | ||
| 2807 | * include/lightning.h, include/lightning/jit_private.h, | |
| 2808 | lib/jit_arm.c, lib/jit_mips.c, lib/jit_ppc.c, lib/jit_x86.c, | |
| 2809 | lib/lightning.c: Make jit_ellipsis implementation not | |
| 2810 | backend specific. It is not intended to handle va_list | |
| 2811 | like objects at runtime, as jit_arg* and jit_getarg* | |
| 2812 | return constant values resolved at parse time, so, effectively | |
| 2813 | it is not possible to create printf like jit functions, as | |
| 2814 | there is no va_start, va_arg, va_end, etc, abstraction. This | |
| 2815 | limitation should be kept for the sake of making new ports | |
| 2816 | easier. | |
| 2817 | ||
| 2818 | 2012-12-14 Paulo Andrade <pcpa@gnu.org> | |
| 2819 | ||
| 2820 | * include/lightning.h, lib/lightning.c: Add two extra wrapper | |
| 2821 | functions to avoid need for excess pointer to/from word casts. | |
| 2822 | ||
| 2823 | * check/lightning.c: Only need for pointer to/from word cast | |
| 2824 | now is jit_movi, update accordingly. | |
| 2825 | ||
| 2826 | 2012-12-13 Paulo Andrade <pcpa@gnu.org> | |
| 2827 | ||
| 2828 | * check/varargs.ok, check/varargs.tst: New test cases implementing | |
| 2829 | simple varargs calls with a large amount of arguments to exercise | |
| 2830 | excess arguments on stack. | |
| 2831 | ||
| 2832 | * include/lightning.h: Include config.h if HAVE_CONFIG_H is | |
| 2833 | defined. | |
| 2834 | ||
| 2835 | * lib/jit_arm.c: Allocate a fpr register, not a gpr one for | |
| 2836 | temporary when pushing varargs arguments in the stack. | |
| 2837 | ||
| 2838 | * lib/jit_arm-swf.c: Correct code changing the wrong offset | |
| 2839 | in jit_absr_d and jit_negr_d in software float. | |
| 2840 | ||
| 2841 | * lib/jit_mips.c: Correct calculation of offsets of arguments | |
| 2842 | on stack. | |
| 2843 | ||
| 2844 | * lib/jit_ppc.c: Correct bogus logic for "next" offset of arguments | |
| 2845 | on stack and adjust for fixed offset of stack arguments. | |
| 2846 | ||
| 2847 | 2012-12-12 Paulo Andrade <pcpa@gnu.org> | |
| 2848 | ||
| 2849 | * include/lightning.h, lib/jit_arm.c, lib/jit_mips.c, | |
| 2850 | lib/jit_ppc.c, lib/jit_x86.c, lib/lightning.c: Change jit_prepare | |
| 2851 | to no longer receive an argument. If receiving an argument, it | |
| 2852 | should be an ABI specifier, not a boolean if varargs or not, | |
| 2853 | and add the new jit_ellipsis call, to specify where the | |
| 2854 | ellipsis is in the C prototype of the function being called. | |
| 2855 | Note that currently it is not supported to define varargs | |
| 2856 | functions and it will be ignored if calling jit_ellipsis not | |
| 2857 | in a prepare/finish* block, but this should be addressed. | |
| 2858 | ||
| 2859 | * check/allocai.tst, check/alu_add.tst, check/alu_and.tst, | |
| 2860 | check/alu_com.tst, check/alu_div.tst, check/alu_lsh.tst, | |
| 2861 | check/alu_mul.tst, check/alu_neg.tst, check/alu_or.tst, | |

| 2867 | check/ldstxr-c.tst, check/ldstxr.tst, check/rpn.tst, | |
| 2868 | check/lightning.c: Update for the change to jit_prepare and | |
| 2869 | addition of jit_ellipsis. | |
| 2870 | ||
| 2871 | 2012-12-11 Paulo Andrade <pcpa@gnu.org> | |
| 2872 | ||
| 2873 | * lib/jit_ppc-cpu.c: Make movr a function that checks arguments | |
| 2874 | so that other code can safely assume it is a noop if src and dst | |
| 2875 | are the same register. | |
| 2876 | Implement rem{r,i}{,_u} as a div{,u}/mul/sub. | |
| 2877 | Correct ANDIS, ORIS and XORIS calls to cast the argument to | |
| 2878 | unsigned before the shift to avoid an assertion if the argument | |
| 2879 | had the topmost bit set. | |
| 2880 | Implement lshi, rshi and rshi_u as functions to test for a | |
| 2881 | zero argument, that would otherwise trigger an assertion when | |
| 2882 | computing the shift value. | |
| 2883 | Do a simple implementation of bm{s,c}{r,i} with a temporary, | |
| 2884 | "andr" of arguments and jump based on comparison with zero. | |
| 2885 | Correct typo in ldxi_c. | |
| 2886 | ||
| 2887 | * lib/jit_ppc-fpu.c: Correct wrong arguments to FDIV* and STF*. | |
| 2888 | ||
| 2889 | * lib/jit_ppc.c: Correct wrong check for 6 instead of 8 integer | |
| 2890 | arguments in registers. If calling a varargs function and | |
| 2891 | passing a float or double argument, also either store the | |
| 2892 | value in the stack or in integer registers, as varargs functions | |
| 2893 | do not fetch it from float registers. | |
| 2894 | Add "case" for new functions and incorrectly missing ones. | |
| 2895 | Call libgcc's __clear_cache, that should know what to do | |
| 2896 | if the hardware needs flushing cache before execution. | |
| 2897 | ||
| 2898 | * lib/lightning.c: Do a simple/trivial logic in jit_regset_scan1, | |
| 2899 | that should make it easier for the compiler to optimize it, and | |
| 2900 | that also corrects the previously wrong code for big endian, and | |
| 2901 | that was causing problems in ppc due to not saving all callee save | |
| 2902 | registers as it was not "finding" them in the regset due to the | |
| 2903 | little endian assumption bug. | |
| 2904 | ||
| 2905 | 2012-12-11 Paulo Andrade <pcpa@gnu.org> | |
| 2906 | ||
| 2907 | * configure.ac: Only default to using the builtin disassembler | |
| 2908 | if on GNU/Linux. This should be temporary, due to requiring | |
| 2909 | /proc/self/exe. | |
| 2910 | Correctly check $target_cpu for powerpc. | |
| 2911 | ||
| 2912 | * include/lightning/jit_ppc.h: Correctly implement jit_v_num. | |
| 2913 | ||
| 2914 | * include/lightning/jit_private.h: Declare proper prototype | |
| 2915 | for jit_init_debug and jit_finish_debug. | |
| 2916 | ||
| 2917 | * lib/jit_ppc-cpu.c: Remove code to save/restore callee save | |
| 2918 | float registers, as it is not required since those float | |
| 2919 | registers are not usable currently. | |
| 2920 | Change prolog and epilog generation to, at least comparing | |
| 2921 | code, match what gcc generates in "gcc -O0", but it is still | |
| 2922 | failing in Darwin PPC, apparently due to the __clear_cache | |
| 2923 | call not being enough, as frequently it will also fail to | |
| 2924 | execute, and the code buffer is all zeroes. | |
| 2925 | ||
| 2926 | * lib/lightning.c: Do not fail in jit_regset_scan1 calls due | |
| 2927 | to passing 64 as argument on computers with 64 registers. | |
| 2928 | ||
| 2929 | 2012-12-10 Paulo Andrade <pcpa@gnu.org> | |
| 2930 | ||
| 2931 | * lib/jit_mips-cpu.c: Correct all current test cases. | |
| 2932 | Call the "xori" not the "XORI" macro for jit_xori implementation, | |
| 2933 | as the XORI macro handles only 16 bit unsigned values. | |
| 2934 | Call the "movr" macro, not the "movi" macro in the special | |
| 2935 | case of adding or subtracting zero. | |
| 2936 | Use the proper temporary register in the jit_andr implementation. | |
| 2937 | ||
| 2938 | 2012-12-09 Paulo Andrade <pcpa@gnu.org> | |

| 2950 | check/branch.tst: New test cases for arithmetic and branch | |
| 2951 | tests. | |
| 2952 | ||
| 2953 | * check/Makefile.am: Update for new test cases. | |
| 2954 | ||
| 2955 | * include/lightning/jit_private.h: Make the jit_reg_free_p | |
| 2956 | macro shared by all backends. Previously was added for the | |
| 2957 | arm backend, but is useful in the x86_64 backend when checking | |
| 2958 | state of "special purpose register". | |
| 2959 | Also add the new jit_class_named register class, that must be | |
| 2960 | or'ed with the register value if calling jit_get_reg expecting | |
| 2961 | an specific value, because the specific register value may be | |
| 2962 | zero, that previously was treated as no register requested. | |
| 2963 | ||
| 2964 | * lib/jit_arm-cpu.c: Correct argument order for T2_MVN. | |
| 2965 | ||
| 2966 | * lib/jit_arm-swf.c: Call the proper function for double | |
| 2967 | divide. The "software float" implementation just calls | |
| 2968 | libgcc functions. | |
| 2969 | ||
| 2970 | * lib/jit_arm.c: Return float/double values in the float | |
| 2971 | register if using the hard float ABI. | |
| 2972 | ||
| 2973 | * lib/jit_x86-cpu.c: Change the can_sign_extend_int_p macro | |
| 2974 | to not include -0x80000000L, because there is code that | |
| 2975 | "abuses" it and thinks it can negate the immediate value | |
| 2976 | after calling that macro. | |
| 2977 | Correct implementation of jit_subi that had a wrong code | |
| 2978 | patch logic doing subtraction with reversed arguments. | |
| 2979 | Correct REX prefix calculation in the jit_muli implementation. | |
| 2980 | Correct logic to get/unget %*ax and %*dx registers in divremr | |
| 2981 | and divremi. | |
| 2982 | Correct divremi that was using the symbolic, unique %*ax | |
| 2983 | value in on place (not using the _REGNO name suffix). | |
| 2984 | Correct cut&paste error causing it to use "xor" instead of | |
| 2985 | "or" in one code path of the jit_ori implementation. | |
| 2986 | Correct several flaws when clobbering registers and/or when | |
| 2987 | one of the arguments was %*cx in the rotshr wrapper function | |
| 2988 | implementing most shift operations. | |
| 2989 | ||
| 2990 | * lib/lightning.c: No longer expect that the backend be smart | |
| 2991 | enough to know what to do when asking for a named register | |
| 2992 | if that register is already an argument or is live. It fails | |
| 2993 | if it is an argument, or if register is live, fails if cannot | |
| 2994 | spill. | |
| 2995 | No longer incorrectly assume that eqr_{f,d} and ltgr_{f,d} are | |
| 2996 | safe to inverse value tests in jump thread optimization. | |
| 2997 | ||
| 2998 | 2012-12-05 Paulo Andrade <pcpa@gnu.org> | |
| 2999 | ||
| 3000 | * check/Makefile.am, check/cvt.ok, check/cvt.tst: Add new | |
| 3001 | "cvt" test case to test conversion from/to int/float types. | |
| 3002 | ||
| 3003 | * check/lightning.c: Only define truncr_{f,d}_l in 64 bit mode. | |
| 3004 | ||
| 3005 | * include/lightning.h: Correct typo that caused it to define | |
| 3006 | jit_truncr_{f,d}_l in 32 bit mode. | |
| 3007 | ||
| 3008 | * lib/jit_arm-cpu.c: Avoid assertion failure in the signed/unsigned | |
| 3009 | extend opcodes generation as it shares an interface for 3 argument | |
| 3010 | opcode generation. | |
| 3011 | ||
| 3012 | * lib/jit_x86-cpu.c: Correct wrong argument passed to | |
| 3013 | jit_unget_reg in the andi implementation and wrong byte | |
| 3014 | unsigned extend code generation. | |
| 3015 | ||
| 3016 | * lib/jit_x86-sse.c: Correct conversion from "word" to float or | |
| 3017 | double as is dependent on wordsize. | |

| 3023 | New test case files testing load clobbering the base and/or | |
| 3024 | index register; | |
| 3025 | ||
| 3026 | * check/ldst.inc: New file with common definition for all the | |

| 3028 | ||
| 3029 | check/Makefile.am, check/ldsti.tst, check/ldstr.tst, | |

| 3033 | 2012-12-05 Paulo Andrade <pcpa@gnu.org> | |

| 3056 | register combinations to verify load/store implementation. | |
| 3057 | ||
| 3058 | * check/Makefile.am: Update for new test cases. | |
| 3059 | ||
| 3060 | * lib/jit_x86-cpu.c: Correct wrong argument order when | |
| 3061 | computing REX prefix for {ld,st}r_T codes; | |
| 3062 | ||
| 3063 | 2012-12-04 Paulo Andrade <pcpa@gnu.org> | |
| 3064 | ||
| 3065 | * lib/jit_mips-fpu.c, lib/jit_mips.c: Implement missing mips | |
| 3066 | jit_sqrtr_{f,d} codes. | |
| 3067 | ||
| 3068 | * check/all.tst, include/lightning.h, lib/jit_print.c: Change | |
| 3069 | declaration order and call order in all.tst of {add,sub}c and | |
| 3070 | {add,sub}x. *c must be called before to set the carry and *x | |
| 3071 | second to use the carry and keep it set. The wrong call order | |
| 3072 | was causing all.tst to fail in mips, where a register is | |
| 3073 | allocated to keep a global carry state. | |
| 3074 | ||
| 3075 | 2012-12-04 Paulo Andrade <pcpa@gnu.org> | |

| 3077 | * include/lightning/jit_mips.h, lib/jit_mips-cpu.c, | |
| 3078 | lib/jit_mips-fpu.c, lib/jit_mips.c: Correct float/double | |
| 3079 | argument handling and make the mips backend pass the initial | |
| 3080 | test cases. | |
| 3081 | ||
| 3082 | * include/lightning.h, ib/jit_print.c, lib/lightning.c: | |
| 3083 | Add extra enum values for argument handling functions that | |
| 3084 | could not be abstracted to the current codes, that is, when | |
| 3085 | float values need to move from/to gpr from/to fpr. It would | |
| 3086 | be more tempting to add such primitives, but they would have | |
| 3087 | wordsize limitations, and it is not expected to add codes | |
| 3088 | with one gpr argument for 64 bit and two for 32 bit. | |
| 3089 | ||
| 3090 | * lib/jit_ppc.c: Check _jit->function before calling jit_epilog() | |
| 3091 | to avoid a runtime exception. | |
| 3092 | ||
| 3093 | 2012-12-04 Paulo Andrade <pcpa@gnu.org> | |
| 3094 | ||
| 3095 | * include/lightning/jit_mips.h, lib/jit_mips.c: Update to | |
| 3096 | make the mips backend compile in a qemu image. | |
| 3097 | ||
| 3098 | * lib/jit_ppc.c: Minor adaptations to help in having the | |
| 3099 | ppc backend compilable. | |
| 3100 | ||
| 3101 | 2012-12-03 Paulo Andrade <pcpa@gnu.org> | |
| 3102 | ||
| 3103 | * configure.ac, include/lightning/jit_private.h, lib/jit_arm-cpu.c, | |
| 3104 | lib/jit_arm-swf.c, lib/jit_arm.c, check/Makefile.am: Correct | |
| 3105 | implementation of the arm backend port to build and pass the | |
| 3106 | current test cases. Tested on armv7 with softfp abi. | |
| 3107 | ||
| 3108 | * lib/jit_disasm.c: Rename and change prototype of static | |
| 3109 | disassemble function as in the arm backend it is required | |
| 3110 | to access state information stored in the jit_state_t object. | |
| 3111 | ||
| 3112 | * check/3to2.tst, check/add.tst: Correct test case code assuming | |
| 3113 | JIT_RO and JIT_RET are the same, and even if they are the same, | |
| 3114 | the logic was incorrect because it must always call jit_retval* | |
| 3115 | to fetch a function call return before any other instruction. | |
| 3116 | The arm backend hash a special condition if jit_retval is not | |
| 3117 | called, because "r0" is not JIT_R0, but is JIT_RET and *also* | |
| 3118 | the first argument for a called function, so JIT_RET must be | |
| 3119 | only used as an argument to jit_retval. | |
| 3120 | ||
| 3121 | 2012-12-03 Paulo Andrade <pcpa@gnu.org> | |
| 3122 | ||
| 3123 | * check/all.tst, check/lightning.c: Only declare or use 64 bit | |
| 3124 | interfaces on 64 bit builds. | |
| 3125 | ||
| 3126 | * check/fib.tst: Use simpler logic to not need preprocessor | |
| 3127 | conditionals for 32 or 64 bit. | |
| 3128 | ||
| 3129 | * include/lightning.h: Only declare 64 bit macros on a 64 bit | |
| 3130 | build. Code using lightning must know about wordsize and the | |
| 3131 | jit generation limitations, also, this way it generates a | |
| 3132 | compile time failure, not a runtime assertion. | |
| 3133 | ||
| 3134 | * include/lightning/jit_x86.h: Correct typo in macro name. | |
| 3135 | ||
| 3136 | * lib/jit_arm.c, lib/jit_arm-cpu.c, lib/jit_mips.c, | |
| 519a9ea1 | 3137 | lib/jit_mips-cpu.c, lib/jit_ppc.c, lib/jit_ppc-cpu.c, |
| 4a71579b PC |
3138 | lib/jit_x86.c, lib/jit_x86-cpu.c: Correct wrong code to get |
| 3139 | current jit function pointer. | |
| 3140 | ||
| 3141 | * lib/lightning.c: Move call to the simplify() optimization | |
| 3142 | to after register liveness is known. Previous code did work | |
| 3143 | by accident but now with proper test cases the problem was | |
| 3144 | noticed. | |
| 3145 | ||
| 3146 | * lib/jit_disasm.c: Always cast bfd_vma to long long when | |
| 3147 | passing it as printf argument. | |
| 3148 | ||
| 3149 | 2012-12-03 Paulo Andrade <pcpa@gnu.org> | |

| 3157 | * lib/jit_ppc.c: Assign copyright ownership to FSF. | |
| 3158 | ||
| 3159 | * lib/jit_x86-cpu.c: Correct integer multiplication that was | |
| 3160 | generating code with reversed register arguments. | |
| 3161 | ||
| 3162 | * check/rpn.ok, check/rpn.tst: New test case file. | |
| 3163 | ||
| 3164 | 2012-12-02 Paulo Andrade <pcpa@gnu.org> | |
| 3165 | ||
| 3166 | * lib/jit_x86-cpu.c, lib/jit_x86-sse.c, lib/jit_x86-x87.c: | |

| 3172 | lib/jit_ppc-cpu.c, lib/jit_ppc-fpu.c, lib/jit_ppc.c: New | |
| 3173 | files implementing initial code different jit backends. | |
| 3174 | ||
| 3175 | * include/lightning/jit_private.h: Add extra field to the | |
| 3176 | private jit_patch_t type, required by the arm port. | |

| 3178 | * lib/Makefile.am: Update for the new backend implementation | |

| 3180 | ||
| 3181 | 2012-12-02 Paulo Andrade <pcpa@gnu.org> | |
| 3182 | ||

| 3185 | ||
| 3186 | 2012-12-02 Paulo Andrade <pcpa@gnu.org> | |
| 3187 | ||
| 3188 | * .gitignore: Update pattern of ignored files. | |
| 3189 | ||
| 3190 | * check/Makefile.am: Add rule to build liblightning.la dependency | |
| 3191 | in case of running "make check" before building the library. | |

| 3231 | ||
| 3232 | * check/Makefile.am: New test suite makefile. | |

| 3240 | ||
| 3241 | * check/all.tst: New file. A generic debug and sample test file | |

| 3244 | of registers. | |

| 3253 | written from scratch, only by <pcpa@gnu.org>, and have now | |
| 3254 | copyright assignment to the FSF. This is the core of the new | |
| 3255 | lightning rework. Previously it was integrated in code with | |
| 3256 | a garbage collector and several custom types like vectors and | |
| 3257 | hash tables, so this first code merge with lightning converts | |
| 3258 | that code into a library extracting only the jit bits, and at | |
| 3259 | first only for x86_64 GNU/Linux. | |
| 3260 | ||

| 3262 | required in the new lightning code. | |
| 3263 | ||
| 3264 | .gitignore, Makefile.am, configure.ac: Update for the new | |

| 3275 | * .gitignore, configure.ac, Makefile.am, doc/Makefile.am: | |
| 3276 | Update for build-aux to m4 rename. | |
| 3277 | ||
| 3278 | 2012-12-01 Paulo Andrade <pcpa@gnu.org> | |
| 3279 | ||
| 3280 | * opcode/Makefile.am, opcode/Makefile.in, opcode/ansidecl.h, | |
| 3281 | opcode/bfd.h, opcode/dis-asm.h, opcode/dis-buf.c, opcode/disass.c, | |
| 3282 | opcode/i386-dis.c, opcode/i386.h, opcode/ppc-dis.c, opcode/ppc-opc.c, | |
| 3283 | opcode/ppc.h, opcode/sparc-dis.c, opcode/sparc-opc.c, opcode/sparc.h, | |
| 3284 | opcode/sysdep.h: Removed. Do not bundle GNU binutils files. | |
| 3285 | ||
| 3286 | * aclocal.m4, configure, Makefile.in, config.h.in, doc/Makefile.in, | |
| 3287 | lightning/Makefile.in, tests/Makefile.in: Removed. Do not maintain | |
| 3288 | autogenerated files that also generate too much diff noise when | |
| 3289 | regenerated in git. | |
| 3290 | ||
| 3291 | * build-aux/help2man, build-aux/texinfo.tex, build-aux/texi2dvi: | |
| 3292 | Removed. Buildenvironment must have an up to date version from | |
| 3293 | upstream installed. | |
| 3294 | ||
| 3295 | * build-aux/config.guess, build-aux/config.sub, build-aux/depcomp, | |
| 3296 | build-aux/install-sh build-aux/mdate-sh build-aux/missing: Removed. | |
| 3297 | Do not maintain a copy of automake files in git. Release tarballs | |
| 3298 | must use an up to date version. | |
| 3299 | ||
| 3300 | * lightningize.in, doc/lightningize.1: Removed. Do not encourage | |
| 3301 | bundling lightning in other packages. It should use a system package | |
| 3302 | or a proper thirdy part subdirectory. | |
| 3303 | ||
| 3304 | * INSTALL: Removed. Autoreconf removes it and creates a symlink | |
| 3305 | when regenerating files, so, avoid conflicts in git and let | |
| 3306 | automake create the symlink. | |
| 3307 | ||
| 3308 | * .gitignore: Add INSTALL and autogenerated files. | |
| 3309 | ||
| 3310 | * configure.ac, Makefile.am: Update for removal of opcode subdir, | |
| 3311 | auto generated files and lightningize. | |
| 3312 | ||
| 3313 | * tests/Makefile.am, tests/3to2.c, tests/add.c, tests/bp.c, | |
| 3314 | tests/fib.c, tests/fibdelay.c, tests/fibit.c, tests/funcfp.c, | |
| 3315 | tests/incr.c, tests/printf.c, tests/rpn.c, tests/rpnfp.c, | |
| 3316 | tests/sete.c, tests/testfp.c: Update for removal of opcode subdir. | |
| 3317 | ||
| 3318 | * doc/Makefile.am: Update for removal of lightningize. | |
| 3319 | ||
| 3320 | * configure.ac, lightning/ppc/funcs.h, lightning/sparc/funcs.h, | |
| 3321 | lightning/i386/fp.h, lightning/i386/core.h, lightning/i386/asm.h, | |
| 3322 | tests/3to2.c, tests/add.c, tests/bp.c, tests/fib.c, tests/fibdelay.c, | |
| 3323 | tests/fibit.c, tests/funcfp.c, tests/incr.c, tests/printf.c, | |
| 3324 | tests/rpn.c, tests/rpnfp.c, tests/sete.c, tests/testfp.c: | |
| 3325 | Remove LIGHTNING_CROSS, it is half supported and incomplete. | |
| 3326 | ||
| 3327 | * tests/3to2.c, tests/funcfp.c, tests/rpnfp.c: Remove preprocessor | |
| 3328 | check on JIT_FPR. If no hardware registers are available, the backend | |
| 3329 | must provide an alternative for software float. | |
| 3330 | ||
| 3331 | * lightning/ppc/core.h, lightning/sparc/core.h, tests/Makefile.am: | |
| 3332 | Remove JIT_NEED_PUSH_POP. It is absolutely not trivial to implement | |
| 3333 | properly on some backends due to stack alignment constraints, and | |
| 3334 | whenever it is required, using jit_allocai and using a properly | |
| 3335 | aligned stack vector, or a heap buffer, is better. | |
| 3336 | ||
| 3337 | * tests/push-pop.c, tests/push-pop.ok: Removed due to | |
| 3338 | JIT_NEED_PUSH_POP no longer available. | |
| 3339 | ||
| 3340 | 2011-02-28 Paolo Bonzini <bonzini@gnu.org> | |
| 3341 | ||
| 3342 | * lightning/i386/core-64.h: Add jit_add{c,x}{i,r}_l, jit_mulr_{l,ul}_, | |
| 3343 | fix jit_mul{i,r}_{l,ul}. | |

| 3365 | ||
| 3366 | 2010-08-15 Paolo Bonzini <bonzini@gnu.org> | |
| 3367 | ||
| 3368 | * lightning/i386/core.h (jit_ldr_c, jit_ldxr_c, jit_ldr_s, | |
| 3369 | jit_ldxr_s): Move... | |
| 3370 | * lightning/i386/core-32.h: ... here. | |

| 3389 | ||
| 3390 | * THANKS: Add Paulo Cesar Pereira de Andrade. | |
| 3391 | * doc/porting.texi: Fix ordering of arguments in jit_stxi. | |
| 3392 | * lightning/i386/core-32.h (jit_replace): Remove cmp argument. | |

| 3449 | ||
| 3450 | * lightning/ppc/funcs.h (jit_flush_code): modified the computation | |
| 3451 | of start/end. The pointer arithmetic was done without casting. It | |
| 519a9ea1 | 3452 | prevented compilation with recent gcc versions. |
| 4a71579b PC |
3453 | * lightning/ppc/core.h (jit_pushr_i): The offset for the store was |
| 3454 | incorrect. Should have been 4 bytes below SP (not above). | |
| 519a9ea1 PC |
3455 | * lightning/ppc/core.h (jit_popr_i): The offset for the load was |
| 3456 | incorrect. Should have been 0 (not +8). | |

| 3485 | the XOR should be on a quadword. | |
| 3486 | * lightning/i386/core-64.h (jit_prolog): Keep 16-byte stack | |
| 3487 | alignment. | |
| 3488 | (jit_ret): Always use LEAVE. | |
| 3489 | ||
| 3490 | 2008-06-13 Laurent Michel <ldm@thorgal.homelinux.org> | |
| 3491 | ||
| 3492 | * lightning/i386/core-64.h: Add (void) casts for C++ compatibility. | |

| 3530 | ||
| 3531 | * lightning/i386/core-32.h: Use separate __APPLE__ and SysV | |
