3 * lib/jit_fallback.c: Implement fallback compare and swap with
4 pthreads.
5 * check/Makefile.am: Update for new cas{r,i} simple test.
6 * check/catomic.c, check/catomic.ok: New test case for
7 simple compare and swap atomic operation.
8 * check/lightning.c: Add entries to be able to use
9 the new compare and swap atomic operation. Still missing
10 a general test, only the basic C version.
11 * include/lightning.h.in: Include pthread.h, even if not
12 needing a fallback compare and swap.
13 * include/lightning/jit_private.h: Add support for a register pair
14 in second argument. Required by the new casr and casi operations.
15 * lib/jit_aarch64-cpu.c, lib/jit_aarch64-sz.c, lib/jit_aarch64.c,
16 lib/jit_ppc-cpu.c, lib/jit_ppc-sz.c, lib/jit_ppc.c, lib/jit_x86-cpu.c,
17 lib/jit_x86-sz.c, lib/jit_x86.c: Implement inline code for compare
18 and swap.
19 * lib/jit_arm-cpu.c, lib/jit_arm-sz.c, lib/jit_arm.c: Implement
20 inline code for compare and swap if cpu is armv7, otherwise, use
21 a fallback with pthreads.
22 * lib/jit_alpha-cpu.c, lib/jit_alpha-sz.c, lib/jit_alpha.c,
23 lib/jit_hppa-cpu.c, lib/jit_hppa-sz.c, lib/jit_hppa.c,

28 lib/jit_sparc-cpu.c, lib/jit_sparc-sz.c, lib/jit_sparc.c: Implement
29 fallback compare and swap with pthreads. At least some of these
30 should be updated for inline code generation.
31 * lib/jit_names.c, lib/jit_print.c: lib/lightning.c: Update for the
32 new compare and swap operation.
33 * doc/body.texi: Add simple documentation of the compare and swap

412022-05-14 Paulo Andrade <pcpa@gnu.org>
42
43 * include/lightning.h.in: Reorder jit_mov{n,z}r in instruction list.
44 * lib/jit_alpha.c, lib/jit_alpha-cpu.c, lib/jit_hppa.c,
45 lib/jit_hppa-cpu.c, lib/jit_ia64.c, lib/jit_ia64-cpu.c,
46 lib/jit_riscv.c, lib/jit_riscv-cpu.c, lib/jit_s390.c,
47 lib/jit_s390-cpu.c, lib/jit_sparc.c, lib/jit_sparc-cpu.c:
48 Implement fallback jit_mov{n,z}r. These are a somewhat cheap
49 implementation, but should be reviewed for the arches that already
50 have a proper conditional move.
51 * lib/jit_arm-sz.c, lib/jit_mips-sz.c: Add missing maximum size
52 estimative and reorder.
53 * lib/jit_aarch64-sz.c, lib/jit_x86-sz.c, lib/jit_ppc-sz.c:
54 Reorder entry to match definition order.

622021-04-03 Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de>
63
64 * check/Makefile.am: Add test for the live instruction.
65 * check/live.ok: New file.
66 * check/live.tst: New file.
67 * doc/body.texi: Add documentation for the live instruction and
68 for jit_get_reg/jit_get_unreg. Fix menu entries.
69 * include/lightning.h.in (jit_get_reg, jit_unget_reg): Expose the
70 macros in the public header file.
71 * include/lightning/jit_private.h (jit_get_reg, jit_unget_reg):
72 Remove the macros from the private header file.
73
742021-04-03 Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de>
75
76 * Makefile.am, check/Makefile.am, doc/Makefile.am,
77 lib/Makefile.am: Include $(top_builddir)/include in include paths
78 for the autoconf-generated header file lightning.h.
79
802021-04-03 Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de>
81
82 * doc/.gitignore: Add version.texi to list of ignored files.
83 * doc/version.texi: Remove file from version control.
84
852020-18-04 Paulo Andrade <pcpa@gnu.org>
86
87 * lib/jit_x86-cpu.c, lib/jit_x86.c: Implement %rip relative
88 calls and jumps on x86_64. Currently very conservative, assuming
89 a jit block can be larger than 2G, so, if a jump or call is in
90 the same jit generation, but target is unknown, use an indirect
91 branch (could have an option to assume a jit code block is
92 never larger than 2G). Also a deoptimization is that now does
93 not always generate ip relative jmpi; previously implicitly
94 assumed jmpi would never be larger than 2G. Overall still an
95 optimization.

972020-23-01 Paulo Andrade <pcpa@gnu.org>
98
99 * lib/lightning.c: Add a proper fix to the condition of considering
100 a register dead at entry of a block when it modifies the register
101 !after! a branch to a target where it is live.
102 The correction is just to split blocks on branches. It uses an
103 extra label per branch, but makes following the code simpler and
104 avoid costly searches.
105
1062020-22-01 Paulo Andrade <pcpa@gnu.org>
107
108 * lib/lightning.c: Correct a special condition of a register
109 only assigned in a block, and incorrectly marked as dead before
110 a jump where the register is live.
111
1122019-10-04 Paulo Andrade <pcpa@gnu.org>
113
114 * check/lightning.c, include/lightning/jit_private.h,
115 include/lightning/jit_x86.h, lib/jit_x86-cpu.c, lib/jit_x86-sz.c,
116 lib/jit_x86.c: Correct issues with MinGW64 that defines _WIN32
117 and needs long long for jit_word_t.
118
1192019-09-16 Paulo Andrade <pcpa@gnu.org>
120
121 * lib/lightning.c: Do not add registers that are never modified
122 to the set of registers to scan for live range, what might
123 consume a lot of cpu time, doing nothing.
124
519a9ea1 1252019-09-16 Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de>
4a71579b
PC
126
127 * include/lightning/jit_x86.h, lib/jit_x86.c: Correct x86_64
128 backend, made %r12 a callee-save register as dictated by the
129 System V AMD64 ABI.
130
1312019-09-16 Paulo Andrade <pcpa@gnu.org>
132
133 * Makefile.am: Do not force CFLAGS for the get_jit_size target.
134 * check/lightning.c: Drop __ppc__ check.
135 * include/lightning.h.in: Drop __ppc__ check. Add new
136 jit_flag_vararg flag, for special case in powerpc 32 bit using
137 the SYSV abi, and need to pass an extra argument during code
138 generation.
139 * include/lightning/jit_ppc.c: Drop __ppc_ check. Remove the
140 ABI_ELFv2 macro, as it now directly checks for the _CALL_ELF
141 value when/if appropriate.
142 * include/lightning/jit_private.h: Drop __ppc_ check. Check for
143 _CALL_AIXDESC to define extra data to handle function
144 descriptors.
145 * lib/jit_ppc-cpu.c: Update to check for _CALL_SYSV; assume
146 !_CALL_SYSV == (_CALL_AIX || _CALL_LINUX). Significant code
147 rework for the SYSV abi.
148 * lib/jit_ppc-sz.c: Update for the SYSV abi.
149 * lib/jit_ppc.c: Update for the SYSV abi. Add matching va_list
150 type. Drop __ppc__ check.
151 * lib/jit_size.c: Drop __ppc_ check.
152 * lib/lightning.c: Drop __ppc__ check. Add proper check for
153 __powerpc__ and _CALL_AIXDESC to manage function descriptors.
154 * lib/size.c: Update to drop __pppc_ check and SYSV abi.
155
1562019-08-30 Paulo Andrade <pcpa@gnu.org>
157
158 * lib/jit_mips-cpu.c: Use JALR to get the same effect as JR, as
159 in mips32r6 JR generates an illegal instruction. Thanks to
160 Bruno Haible for providing a patch and the information, reported at
161 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=925129
162 * THANKS: update.

165
166 * include/lightning/jit_private.h: Move definition of offsetof
167 from the public header file here.
168
169 * configure.ac, include/Makefile.am, include/lightning.h,
170 include/lightning.h.in: Generate lightning.h from lightning.in.h
171 and remove the dependence on config.h from the public header file.
172
1732019-06-04 Paulo Andrade <pcpa@gnu.org>
174
175 * include/lightning/jit_riscv.h, lib/jit_riscv-cpu.c,
176 lib/jit_riscv-fpu.c, lib/jit_riscv-sz.c, lib/jit_riscv.c:
177 Implement riscv port. Only 64 bit Linux supported. Built on
178 Fedora 28 image.
179
180 * check/all.tst, check/float.tst, configure.ac, include/lightning.h,
181 include/lightning/Makefile.am, include/lightning/jit_private.h,
182 lib/Makefile.am, lib/jit_disasm.c, lib/jit_size.c, lib/lightning.c:
183 Minor updates for the new riscv port.
184
1852019-06-04 Paulo Andrade <pcpa@gnu.org>
186
187 * lib/jit_alpha.c lib/jit_ia64.c lib/jit_mips.c lib/jit_sparc.c:
188 Correct assertion of _jitc->regarg after emiting an instruction.
189 jit_carry may be set, but not an argument to the current instruction.
190
1912019-06-01 Paulo Andrade <pcpa@gnu.org>
192
193 * lib/lightning.c: Correct assertion on jit_unget_reg when the
194 argument is jit_carry, and jit_carry was not used in the
195 instruction.
196
1972019-06-01 Paulo Andrade <pcpa@gnu.org>
198
199 * include/lightning/jit_private.h: Remove no longer need
200 setmask field of jit_block_t and blockmask from jit_compiler_t.
201
202 * lib/lightning.c: Rework of register live and unknown state
203 information during jit generation. It no longer recurses nor
204 do dangerous bit unset of registers in unknown state. The
205 only pitfall known, that must be taken care now is that jmpr
206 (or jmpi to not a jit node) is treated as a function call, as
207 otherwise it would need to consider all registers live, and
208 spill/reload during all jit generation.
209
2102018-12-28 Paulo Andrade <pcpa@gnu.org>
211
212 * lib/jit_disasm.c: Release bfd handle. Thanks for patch to
213 Marc Nieper-Wißkirchen.
214
2152018-08-30 Paulo Andrade <pcpa@gnu.org>
216
217 * lib/jit_disasm.c: Add hints to select hppa disassembler.
218
219 * lib/jit_hppa-cpu.c: Correct address of vastart when all
220 argument registers were used as non vararg arguments.
221
222 * lib/jit_hppa-fpu.c: Disable load/store of rv,ix,rb where
223 rv is the value, ix is an register or integer offset and rb
224 is a base register. These should be better tested, as they do
225 not work on all environments (fail on qemu-hppa).
226
2272018-04-20 Paulo Andrade <pcpa@gnu.org>
228
229 * include/lightning/jit_private.h: Add new register classes to
230 flag float registers and double only registers, required for sparc64
231 where only low 32 bit fpr registers can be used for single precision
232 operations.
233 Add new 128 bit jit_regset_t type for sparc64 register set.
234
235 * include/lightning/jit_sparc.h, lib/jit_sparc-cpu.c, lib/jit_sparc-fpu.c,
236 lib/jit_sparc-sz.c, lib/jit_sparc.c: Update for 64 bits sparc.
237
238 * lib/lightning.c: Update for new jit_regset_t required for sparc64.
239
2402018-02-26 Paulo Andrade <pcpa@gnu.org>
241
242 * check/lightning.c, include/lightning.h: Add the new jit_va_push
243 interface. That should be called when passing a va_list to a C
244 function. This is required because on Alpha a va_list is passed
245 by value, and lightning does not know about data types, so, cannot
246 understand it is pushing a va_list as argument.
247
248 * lib/jit_names.c, lib/lightning.c: Minor changes for the new
249 jit_code_va_push.
250
251 * check/cva_list.c: Update only test case using jit_va_push, to
252 pass a va_list to a C function.
253
254 doc/body.texi: Better documentation of the varargs interface.
255
256 * jit_alpha.c, jit_alpha-cpu.c: Update to properly push a
257 C va_list and correctly calculate varargs offset.
258
259 * lib/jit_aarch64-sz.c, lib/jit_aarch64.c, lib/jit_alpha-sz.c,
260 lib/jit_arm-sz.c, lib/jit_arm.c, lib/jit_hppa-sz.c, lib/jit_hppa.c,
261 lib/jit_ia64-sz.c, lib/jit_ia64.c, lib/jit_mips-sz.c, lib/jit_mips.c,
262 lib/jit_ppc-sz.c, lib/jit_ppc.c, lib/jit_s390-sz.c, lib/jit_s390.c,
263 lib/jit_sparc-sz.c, lib/jit_sparc.c, lib/jit_x86-sz.c, lib/jit_x86.c:
264 Update for the new jit_va_push interface.
265
2662018-02-22 Paulo Andrade <pcpa@gnu.org>
267
268 * lib/jit_alpha-cpu.c: Always set t12 to the address of the
269 current function, to properly work on all systems. Previously
270 the shortcut did only work on Tru64. For Linux and glibc the
271 change is required.
272
2732018-02-22 Paulo Andrade <pcpa@gnu.org>
274
275 * lib/jit_aarch64.c, lib/jit_alpha.c, lib/jit_arm.c,
276 lib/jit_mips.c, lib/jit_ppc.c, lib/jit_sparc.c, lib/jit_x86.c:
277 Correct wrong logic in usage of jit_live in jit_retr. The
278 problem is that if a temporary is required during epilog,
279 the return register might be allocated, so, jit_live must always
280 be used.
281
2822018-01-31 Paulo Andrade <pcpa@gnu.org>
283
284 * lib/lightning.c: Avoid deep recursions when computing live
285 register ranges.
286
2872018-01-31 Paulo Andrade <pcpa@gnu.org>
288
289 * lib/jit_mips-cpu.c: Correct frame size and varargs
290 initialization for the n32 abi.
291 * lib/jit_mips.c, lib/jit_mips-fpu.c: Correct 32 bit abis
292 in big-endian.
293
2942017-09-13 Paulo Andrade <pcpa@gnu.org>
295
296 * configure.ac: Add check for binutils 2.29 prototype to the
297 disassembler function.
298 * lib/jit_disasm.c: Adapt for binutils 2.29 change.
299
3002017-06-09 Paulo Andrade <pcpa@gnu.org>
301
302 * include/lightning/jit_private.h, lib/lightning.c: Add a
303 second pass from start when computing register live ranges.
304 This should be used temporarily, and is required for certain
305 loop constructs, with several consecutive blocks not referencing
306 a live register.
307
3082016-05-05 Paulo Andrade <pcpa@gnu.org>
309
310 * lib/lightning.c: Correct wrong movr simplification,
311 remove no longer needed code to set return registers live
312 and update live register set when reaching a label boundary,
313 but do not descend if the block has been already visited.
314 The later need some tuning for complex code generation, where
315 it will still have issues.
316
3172015-11-30 Paulo Andrade <pcpa@gnu.org>
318
319 * doc/body.texi: Change documentation to no longer say
320 it is a variant of the Fibonacci sequence, and document
321 a proper implementation.
322 Thanks to Jon Arintok for pointing out that the Fibonacci
323 sequence generation was incorrect. It was documented, but
324 still confusing.
325
326 * check/fib.tst, check/fib.ok, check/bp.tst, check/bp.ok,
327 doc/ifib.c, doc/rbif.c: Implement a proper Fibonacci
328 sequence implementation.
329
3302015-07-03 Paulo Andrade <pcpa@gnu.org>
331
332 * lib/jit_mips-cpu.c: Correct definition of htonr_ul.
333 Correct prolog/epilog/va* routines to work on o64 abi.
334
335 * lib/jit_mips-fpu.c: Correct load of double literal
336 argument when not using a data buffer.
337 Remove alignment correction in vaarg_d if using the
338 new mips abi.
339
340 * lib/jit_mips.c: Correct code to allow creating variadic
341 jit functions when using the new mips abi.
342
343 * lib/jit_rewind.c: Minor adjust for rewind when using
344 the new mips abi, if there are varargs arguments in
345 registers.
346
3472015-06-06 Paulo Andrade <pcpa@gnu.org>
348
349 * lib/jit_ia64-cpu.c: Search backward for the last output
350 register used, otherwise would stop too early if a float
351 argument used the slot.
352 Correct offset of first va_list argument, and use proper
353 va_list abi.
354
355 * lib/jit_ia64-fpu.c: Add new functions to move a gpr
356 to a fpr register, to counterpart the ones that move a
357 fpr to a gpr. These are required to properly implement
358 jit_getarg*_{f,d} on complex prototypes, or variadic
359 jit functions.
360
361 * lib/jit_ia64-sz.c: Update for support to jit variadic
362 functions.
363
364 * lib/jit_ia64.c: Implement proper abi for variadic
365 jit functions.
366
3672015-06-04 Paulo Andrade <pcpa@gnu.org>
368
369 * lib/jit_rewind.c: New file implementing generic functions
370 to "rewind", or rewrite IR code sequences.
371
372 * include/lightning.h: Add several new codes, that previously
373 were a function call, that would synthesize the operation.
374 Now, there is a code for the operation, and a new flag to
375 know an operation is synthesized.
376
377 * include/lightning/jit_private.h: Add several new macros to
378 help construct synthesized IR code sequences.
379
380 * lib/Makefile.am: Update for lib/jit_rewind.c.
381
382 * lib/jit_disasm.c: Update for a small rework on jit_node_t,
383 so that --enable-devel-disassembler does not need a change
384 in the layout of jit_node_t.
385
386 * lib/jit_names.c: Update for the new codes.
387
388 * lib/jit_print.c: Update to print more readable output, and
389 flag synthesized IR code sequences.
390
391 * lib/jit_aarch64-sz.c, lib/jit_aarch64.c,
392 lib/jit_arm-sz.c, lib/jit_arm.c, lib/jit_x86-sz.c,
393 lib/jit_x86.c: Update for new synthesized IR code sequences.
394
395 * lib/jit_ppc-cpu.c, lib/jit_ppc-fpu., lib/jit_ppc-sz.c,
396 lib/jit_ppc.c, lib/jit_mips-cpu.c, lib/jit_mips-fpu.c,
397 lib/jit_mips-sz.c, lib/jit_mips.c, lib/jit_s390-fpu.c,
398 lib/jit_s390-sz.c, lib/jit_s390.c: Update for new synthesized
399 IR code sequences and correct bugs in the initial varargs
400 implementation support.
401
402 * lib/jit_alpha-sz.c, lib/jit_alpha.c, lib/jit_hppa-sz.c,
403 lib/jit_hppa.c, lib/jit_ia64-sz.c, lib/jit_ia64.c,
404 lib/jit_sparc-sz.c, lib/jit_sparc.c: Add generic, untested
405 support for the new synthesized IR code sequences. Known
406 most likely broken right now, and should be corrected once
407 access to these hosts is available.
408
409 * lib/lightning.c: Update for new IR codes, and add support
410 for not yet existing instructions that change third argument.
411
412 * size.c: Change to use different tables for LE and BE PowerPC.
413 Correct a wrong endif for x32.
414
4152015-05-25 Paulo Andrade <pcpa@gnu.org>
416
417 * check/cva_list.c: New file implementing a test to ensure
418 the value returned by jit_va_start is a valid C va_list.
419
420 * check/va_list.ok: New simple helper file, as now the
421 va_list.tst test is enabled.
422
423 * check/va_list.tst: Rewritten for an extensive variadic
424 jit functions test.
425
426 * check/Makefile.am: Update for the new tests.
427
428 * lib/jit_arm-cpu.c, lib/jit_arm-swf.c, lib/jit_arm-vfp.c,
429 lib/jit_arm.c: Correct broken software float in a previous
430 commit. Note that the hard float abi implementation is known
431 broken at this time, for special cases involving variadic
432 functions, and should be corrected next.
433
434 lib/jit_x86-cpu.c, lib/jit_x86-sz.c, lib/jit_x86.c: Correct
435 the jit_va_list_t semantics to match C va_list.
436

438
439 * lib/Makefile.am: Bump library major. This is a preparation
440 for a rework that was due for quite some time, but that is
441 now required to properly implement variadic jit functions.
442 The rework is mainly required to know at prolog parsing, if
443 a function is variadic or not. This will benefit a few
444 backends, and is mandatory for the hard float arm abi.
445 The rework was already planned for quite some time, to
446 be able to use a variable stack framesize, and for leaf
447 functions optimization where applicable.
448 The change will be source compatible, but will change
449 some internals, and jit_code_t values, as some new will
450 be added.
451 The only behavior change is that, jit_arg_register_p may
452 change return value on hard float arm abi, if called before
453 or after jit_ellipsis. Common sense anyway, would say to
454 make that call after jit_ellipsis, but documentation
455 should be updated for it.
456
4572015-05-24 Paulo Andrade <pcpa@gnu.org>
458
459 * lib/jit_aarch64-fpu.c, lib/jit_aarch64.c: Correct base
460 aarch64 varargs code.
461
4622015-05-24 Paulo Andrade <pcpa@gnu.org>
463
464 * check/lightning.c: Clearly run check if clang is the system
465 compiler.
466
4672015-05-20 Paulo Andrade <pcpa@gnu.org>
468
469 * lib/jit_sparc-cpu.c, lib/jit_sparc-fpu.c, lib/jit_sparc.c:
470 Add base support to jit vararg functions to the sparc backend.
471
4722015-05-20 Paulo Andrade <pcpa@gnu.org>
473
474 * lib/jit_alpha-cpu.c, lib/jit_alpha-fpu.c, lib/jit_alpha.c:
475 Add base support to jit vararg functions to the alpha backend.
476
4772015-05-19 Paulo Andrade <pcpa@gnu.org>
478
479 * lib/jit_hppa-cpu.c, lib/jit_hppa-fpu.c, lib/jit_hppa.c:
480 Add base support to jit vararg functions to the hppa backend.
481
4822015-05-10 Paulo Andrade <pcpa@gnu.org>
483
484 * lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c, lib/jit_ia64.c:
485 Add base support to jit vararg functions to the ia64 backend.
486
4872015-05-10 Paulo Andrade <pcpa@gnu.org>
488
489 * lib/jit_ia64-fpu.c, lib/jit_ia64.c: Correct movi_d_w
490 and movi_f_w implementation to work when not using a
491 data buffer. This causes the check varargs.tst to
492 work when passing "-d" to the lightning test tool.
493
4942015-05-10 Paulo Andrade <pcpa@gnu.org>
495
496 * lib/jit_ia64.c: Implement inline assembly cache flush,
497 required on multiprocessor systems.
498
4992015-05-06 Paulo Andrade <pcpa@gnu.org>
500
501 * lib/jit_mips-cpu.c, lib/jit_mips-fpu.c, lib/jit_mips.c:
502 Add base support to jit vararg functions to the mips backend.
503 Currently only supported on the o32 abi, until access to a
504 n32 system is arranged.
505
5062015-05-05 Paulo Andrade <pcpa@gnu.org>
507
508 * lib/jit_ppc-cpu.c, lib/jit_ppc-fpu.c, lib/jit_ppc.c:
509 Add base support to jit vararg functions to the PowerPC backend.
510
5112015-05-02 Paulo Andrade <pcpa@gnu.org>
512
513 * lib/jit_s390-cpu.c, lib/jit_s390-fpu.c, lib/jit_s390.c:
514 Add base support to jit vararg functions to the s390 backend.
515
5162015-05-01 Paulo Andrade <pcpa@gnu.org>
517
518 * lib/jit_arm-cpu.c, lib/jit_arm-swf.c, lib/jit_arm-vfp.c,
519 lib/jit_arm.c: Add base support to jit vararg
520 functions to the arm backend.
521
5222015-04-30 Paulo Andrade <pcpa@gnu.org>
523
524 * lib/jit_aarch64-cpu.c, lib/jit_aarch64-fpu.c,
525 lib/jit_aarch64.c: Add base support to jit vararg
526 functions to the aarch64 backend.
527
5282015-04-27 Paulo Andrade <pcpa@gnu.org>
529
530 * include/lightning.h, include/lightning/jit_private.h,
531 lib/jit_names.c, lib/lightning.c: Add initial support
532 for the new jit_va_start, jit_va_arg, jit_va_arg_d, and
533 jit_va_end interfaces. The jit_va_start call is supposed
534 to return a va_list compatible pointer, but not yet
535 decided if it will be "declared" stdarg compatible,
536 as for now only x86 support has been added (and should
537 be compatible), but issues may arise on other backends.
538
539 * check/lightning.c: Add wrappers to call the new jit_va_*
540 interfaces.
541
542 * lib/jit_x86-cpu.c, lib/jit_x86.c: Implement the new
543 jit_va_* for x86.
544
545 * lib/jit_x86-sz.c: Add fields, but not yet fully updated,
546 as this is an intermediate commit.
547
548 * lib/jit_aarch64-sz.c, lib/jit_aarch64.c,
549 lib/jit_alpha-sz.c, lib/jit_alpha.c,
550 lib/jit_arm-sz.c, lib/jit_arm.c,

555 lib/jit_s390-sz.c, lib/jit_s390.c,
556 lib/jit_sparc-sz.c, lib/jit_sparc.c: Prepare for the
557 new jit_va_* interfaces. Not yet implemented, and will
558 cause an assertion if used.
559
560 * check/va_list.tst: Simple early test case, that works
561 on x86_64, x32, ix86, cygwin, and cygwin64.
562
5632015-02-17 Paulo Andrade <pcpa@gnu.org>
564
565 * include/lightning.h, include/lightning/jit_private.h,
566 lib/jit_aarch64-cpu.c, lib/jit_aarch64.c,
567 lib/jit_alpha-cpu.c, lib/jit_alpha.c,

573 lib/jit_s390-cpu.c, lib/jit_s390.c,
574 lib/jit_sparc-cpu.c, lib/jit_sparc.c,
575 lib/jit_x86-cpu.c, lib/jit_x86.c: Implement the new
576 jit_allocar(offs, size) interface, that receives
577 two integer registers arguments, allocates space
578 dynamically in the stack, returns the offset in
579 the first argument, and uses the second argument
580 for the size in bytes of the memory to be allocated.
581
582 * check/allocar.ok, check/allocar.tst: New files
583 implementing test cases for the new jit_allocar
584 interface.
585
586 * check/Makefile.am, check/lightning.c: Update for
587 the new test case and interface.
588
589 * doc/body.texi: Add documentation of the new
590 interface.
591
5922015-02-17 Paulo Andrade <pcpa@gnu.org>
593
594 * include/lightning/jit_x86.h, lib/jit_x86-cpu.c,
595 lib/jit_x86-x87.c: No longer make st(7) available.
596 Need to keep one x87 slots empty to avoid exceptions.
597 This has the side effect of no longer needing the
598 hackish emms instruction before a function call.
599
6002015-02-16 Paulo Andrade <pcpa@gnu.org>
601
602 * lib/lightning.c: Remove the jit_regno_patch bitfield
603 register fields before actual emit, as it is only really
604 used before emit, otherwise, on special conditions it
605 may consider live registers as dead during code emit.
606
6072015-02-15 Paulo Andrade <pcpa@gnu.org>
608
609 * lib/jit_x86-cpu.c, lib/jit_x86-sse.c, lib/jit_x86-x87.c:
610 Correct encoding of ldxr* stxr* in the x32 abi. If the
611 displacement register is negative, it would generate
612 a 64 bit instruction with a 32 bit unsigned displacement.
613
614 * check/ranger.tst, check/ranger.ok: New files, implementing
615 a test case for negative loads and stores. This is range.tst
616 converted to use registers instead of immediate offsets.
617
618 check/Makefile.am: Update for the new test case.
619
6202015-02-07 Paulo Andrade <pcpa@gnu.org>
621
622 * lib/jit_size.c: Preventively use at least 144 bytes
623 if JIT_INSTR_MAX is less than it. The logic is not
624 guaranteed to be 100% precise, it is mostly heuristics
625 to allocate a buffer with as close as possible size,
626 but a wrong value may cause code generation to write
627 past the end of the buffer.
628
6292015-02-03 Paulo Andrade <pcpa@gnu.org>
630
631 * lib/lightning.c: Correct the reason the bug in
632 simplify_stxi was not triggered before, it was due to
633 incorrectly resetting the value->code field, what was
634 causing it to never properly optimize:
635 stxi Im0 Rb0 Rt0
636 ldxi Rt1 Rb1 Im1
637 when Rb0 == Rb1, Rt0 == Rt1 and Im0 == Im1
638 There was another possible issue, that has been also
639 addressed in this commit, that would be the case of
640 Rbn == Rtn, where no redundancy removal is possible.
641
6422015-02-03 Paulo Andrade <pcpa@gnu.org>
643
644 * lib/lightning.c: Correct wrong check in simplify_stxi.
645 The test was incorrectly comparing the target register
646 and the displacement offset. This was a time bomb bug,
647 that would trigger in code like:
648 stxi Im0 Rb0 Rt0
649 stxi Im1 Rb1 Rt1
650 if Rb0 == Rb1 && Rt0 == Rt1 && Im0 == Rt1, that is,
651 the wrong check was Im0 == Rt1, instead of the supposed
652 Im0 == Imm1 (that was what the code mean't to do). It
653 was removing the second stxi assuming it was redundantly
654 generated; as that is not uncommon pattern on
655 translators generating jit.
656
6572015-02-02 Paulo Andrade <pcpa@gnu.org>
658
659 * configure.ac, include/lightning/jit_private.h,
660 lib/jit_aarch64.c, lib/jit_alpha.c, lib/jit_arm.c,
661 lib/jit_disasm.c, lib/jit_hppa.c, lib/jit_ia64.c,
662 lib/jit_mips.c, lib/jit_ppc.c, lib/jit_print.c,
663 lib/jit_s390.c, lib/jit_sparc.c, lib/jit_x86.c: Add a new
664 --enable-devel-disassembler option, that should be used
665 during development, or lightning debug. This option
666 intermixes previous jit_print and jit_disassemble
667 output, making it easier to visualize what lightning
668 call was used, and what code was generated.
669
6702015-01-31 Paulo Andrade <pcpa@gnu.org>
671
672 * lib/jit_arm-cpu.c, lib/jit_arm.c: Only limit to 24 bit
673 displacement non conditional jump in the same jit_state_t.
674
6752015-01-19 Paulo Andrade <pcpa@gnu.org>
676
677 * doc/body.texi: Reorder documentation, making jit_frame
678 and jit_tramp the lightning response to the need of
679 trampolines, continuations and tail call optimizations.
680 A pseudo code example of a factorial function was added.
681 Also added a section for description of the available
682 predicates.
683
684 * doc/fact.c: New file, implementing a simple example of
685 a translation of a trivial, recursive, tail call optimization
686 into lightning calls. This is the conversion to functional C
687 code of the example in doc/body.texi.
688
689 * doc/Makefile.am: Update for the next test case.
690
6912015-01-17 Paulo Andrade <pcpa@gnu.org>
692
693 * include/lightning.h, lib/jit_aarch64.c,
694 lib/jit_alpha.c, lib/jit_arm-vfp.c, lib/jit_arm.c,
695 lib/jit_hppa.c, lib/jit_ia64.c, lib/jit_mips.c,
696 lib/jit_ppc.c, lib/jit_s390.c, lib/jit_sparc.c,
697 lib/jit_x86.c: Add the new jit_arg_register_p predicate.
698 The predicate is expected to be used to know if an
699 argument is in a register, what would need special
700 handling if code that can overwrite non callee save
701 registers is executed.
702
703 * check/carg.c: New test case to check consistency and
704 expected usage of jit_arg_register_p.
705
706 * check/Makefile.am: Update for new test case.
707
7082015-01-17 Paulo Andrade <pcpa@gnu.org>

722 lib/jit_ppc.c, lib/jit_s390.c,
723 lib/jit_sparc.c, lib/jit_x86.c: Remove jit_arg_reg_p and
724 jit_arg_f_reg_p from a public header, and define it only
725 on port specific files where an integer offset is used
726 to qualify an argument identifier. Exported code expects
727 an opaque pointer (but of jit_node_t* type) to "qualify"
728 an argument identifier.
729 This patch, and the code review/simplification done during
730 it also corrected some bugs:
731 o Inconsistent jit_arg_d value of double argument after 3
732 integer arguments in arm for jit_functions; tested, C
733 functions were being properly called.
734 o Inconsistent use of getarg_{f,d} and putarg*_{f,d} on
735 s390 (32-bit) that happened to not have a proper test
736 case, as it would only happen for jit functions, and
737 tested, called C functions had proper arguments.
738 o Corrected a "last minute" correction that did not go
739 to the committed version, and would not compile on hppa,
740 due to bad _jit_putargi_d prototype definition.
741
7422015-01-17 Paulo Andrade <pcpa@gnu.org>
743
744 * doc/body.texi: Correct wrong/outdated information for
745 hton*, pusharg* and ret*, and add missing documentation
746 for rsb*, qmul*, qdvi* and putarg*.
747
7482015-01-15 Paulo Andrade <pcpa@gnu.org>
749
750 * configure.ac, lib/jit_disasm.c: Rewrite workaround
751 to apparent problem to initialize powerpc disassembler.
752
7532015-01-15 Paulo Andrade <pcpa@gnu.org>
754

757 lib/jit_ia64.c, lib/jit_mips.c, lib/jit_ppc.c,
758 lib/jit_s390.c, lib/jit_sparc.c, lib/jit_x86.c:
759 Implement jit_putarg*. It works as a mix of jit_getarg*
760 and jit_pusharg*, in the way that the first argument is
761 a register or immediate, and the second is a pointer
762 returned by jit_arg*. The use of the interface is to change
763 values of arguments to the current jit function.
764
765 * check/put.ok, check/put.tst: New test cases exercising
766 the new jit_putarg* interface.
767
768 * check/Makefile.am, check/lightning.c: Update for the
769 new test case and interface.
770

775 Renamed s390x* files to s390*.
776
777 * check/float.tst, check/lightning.c, configure.ac,
778 include/lightning.h, include/lightning/Makefile.am,

787 lib/jit_s390x.c, lib/jit_size.c, lib/lightning.c:
788 Add support for generating jit for s390 32 bit. This change
789 also removed %f15 from the list of temporaries fpr registers;
790 it was not being used, but if were, it would corrupt the
791 stack frame because the spill address would overwrite grp
792 offsets.
793
7942014-12-26 Paulo Andrade <pcpa@gnu.org>
795
796 * lib/jit_ppc-cpu.c, lib/jit_ppc.c: Correct some endianess issues

798
7992014-12-26 Paulo Andrade <pcpa@gnu.org>
800
801 * lib/jit_ppc-cpu.c: Add mcrxr instruction emulation,
802 as this instruction has been phased out, and should be
803 implemented as a kernel trap.
804
8052014-12-26 Paulo Andrade <pcpa@gnu.org>
806
807 * lib/jit_arm.c: Better check for need to flush constants
808 before the pool being no longer reachable.
809
8102014-12-25 Paulo Andrade <pcpa@gnu.org>
811
812 * include/lightning.h: Split jit_htonr in the new 3 interfaces
813 jit_htonr_us, jit_htonr_ui and jit_htonr_ul, the later only
814 available on 64 bit. The plain/untyped jit_htonr macro call
815 maps to the wordsize one.

826 Update backends for the new jit_htonr*.
827 * check/lightning.c, lib/jit_names.c, lib/lightning.c:
828 Update for the new jit_htonr* interfaces.
829 * check/Makefile.am: Update for new test cases.

839
8402014-12-24 Paulo Andrade <pcpa@gnu.org>
841
842 * lib/jit_names.c: Add missing rsbi_f and rsbi_d strings.
843
8442014-12-21 Paulo Andrade <pcpa@gnu.org>
845
846 * lib/jit_arm.c: Call __clear_cache for every page.
847 This should only be required for older boards or
848 toolchain setup, but has been reported to be required
849 for lightning at some point.
850
8512014-12-21 Paulo Andrade <pcpa@gnu.org>
852
853 * lib/jit_arm.c: Correct check to guard overflow of index
854 of constants from program counter.
855
8562014-11-24 Paulo Andrade <pcpa@gnu.org>
857
858 * lib/lightning.c: Remove an optimization to calee save

876 only use those if the register is even.
877
878 * check/check.arm.swf.sh, check/check.arm4.swf.sh: New files
879 to test LDRD and STRD, as well as the alternate code path
880 when those are not available, in the .arm4. test case.
881
882 * check/Makefile.am: Update for the new test cases.
883
8842014-11-08 Paulo Andrade <pcpa@gnu.org>
885
886 * include/lightning/jit_private.h, lib/jit_aarch64.c,
887 lib/jit_alpha.c, lib/jit_arm.c, lib/jit_hppa.c,
888 lib/jit_ia64.c, lib/jit_mips.c, lib/jit_ppc.c,
889 lib/jit_s390x.c, lib/jit_sparc.c, lib/jit_x86.c:
890 Implement a private jit_flush call, that flushes
891 the cache, if applicable, aligning down to the
892 previous and up to the next page boundary.
893
8942014-11-08 Paulo Andrade <pcpa@gnu.org>
895
896 * check/ctramp.c: New file. It just repeats the test
897 of tramp.tst, but using two jit_state_t, what should
898 test possible issues with two contexts, and also validate
899 jit_tramp works on backends with function descriptions.
900
901 * check/Makefile.am: Update for new test case.
902
9032014-11-03 Paulo Andrade <pcpa@gnu.org>
904
905 * include/lightning/jit_mips.h: Do not make the t9 register
906 JIT_R11 (or JIT_R7 for n32 or n64 abi) available. Previously
907 it cause problems if one expects it to not be changed in a
908 function call. For example, calling a jit function, where it
909 really does not need to be changed.
910
9112014-10-26 Paulo Andrade <pcpa@gnu.org>
912
913 * lib/jit_aarch64.c, lib/jit_alpha.c, lib/jit_arm.c,
914 lib/jit_hppa.c, lib/jit_ia64.c, lib/jit_mips.c, lib/jit_ppc.c,
915 lib/jit_s390x.c, lib/jit_sparc.c, lib/jit_x86.c: Add an
916 assertion to all code generation "drivers" to ensure
917 _jitc->regarg is empty or in an expected state, after
918 translation of a lightning instruction to native code.
919 This change was a brute force test to find out other cases
920 of a temporary not being release (like was happening with
921 _bmsi and _bmci on x86), but no other case was found,
922 after running make check, with assertions enabled, on all
923 backends.
924
9252014-10-26 Paulo Andrade <pcpa@gnu.org>
926
927 * lib/jit_x86-cpu.c: Correct a register allocation leak in
928 _bmsi and _bmci.
929
9302014-10-25 Paulo Andrade <pcpa@gnu.org>
931
932 * lib/jit_disasm.c: Do not cause an fatal error if init_jit
933 fails in the jit_init_debug call.
934
9352014-10-24 Paulo Andrade <pcpa@gnu.org>
936
937 * lib/jit_ia64.c, lib/jit_ppc.c: Correct handling of function
938 descriptor when first prolog is a jit_tramp prolog. The
939 test case was using the same jit_context_t, so was not
940 triggering this condition.
941
942 * lib/jit_ppc-cpu.c: Properly handle jump displacements that
943 do not fit on 24 powerpc. This required changing from previous
944 "mtlr reg, blr" to "mtctr reg, bctr" to properly handle
945 the logic to "hide" function descriptors, but that would
946 also be required as the proper jit_jmpr when/if implementing
947 optimizations to leaf functions (was working with blr because
948 it is saved/reloaded in prolog/epilog).
949
9502014-10-21 Paulo Andrade <pcpa@gnu.org>
951
952 * include/lightning.h, lib/lightning.c: Add three predicates
953 to query information about labels. jit_forward_p(label)
954 will return non zero if the label is "forward", that is
955 need a call to jit_link(label), jit_indirect_p(label)
956 that returns non zero if the label was created with the
957 jit_indirect() call, and jit_target_p(label) that will
958 return non zero if there is at least one jump patched
959 to land at that label.
960
9612014-10-18 Paulo Andrade <pcpa@gnu.org>
962
963 * check/range.ok, check/range.tst: New test case designed
964 to catch incorrect code generation, usually due to incorrect
965 test of immediate size. The test checks a large amount of
966 encodings in "power of two" boundaries. This test exorcises
967 a significant amount of code paths that was previously not
968 tested.
969
970 * check/Makefile.am: Add range test to make check target.
971
972 * lib/jit_aarch64-cpu.c: Correct wrong address calculation
973 for stxi_c, stxi_s, stxi_i and stxi_l when the offset is
974 too large.
975
976 * lib/jit_mips-fpu.c: Correct wrong size test to check if
977 an immediate can be encoded in a float or double store.
978
979 * lib/jit_s390x-cpu.c: Correct inverted encoding to stxi_s
980 when the offset cannot be encoded, and fallbacks to an
981 alternate encoding in 2 instructions.
982
9832014-10-17 Paulo Andrade <pcpa@gnu.org>
984
985 * check/alu_rsb.ok, check/alu_rsb.tst: New files implementing
986 tests for jit_rsb*.
987
988 * check/Makefile.am, check/lightning.c, include/lightning.h,
989 lib/jit_aarch64-cpu.c, lib/jit_aarch64-fpu.c, lib/jit_aarch64-sz.c,

1002 lib/jit_x86-sse.c, lib/jit_x86-sz.c, lib/jit_x86-x87.c,
1003 lib/jit_x86.c, lib/lightning.c: Implement jit_rsb*. This
1004 was a missing lightning 1.x interface, that on most
1005 backends is synthesized, but on a few backends (hppa and ia64),
1006 it can generate better code as on those there is, or the
1007 only instruction with an immediate is in "rsb" format
1008 (left operand).
1009
10102014-10-17 Paulo Andrade <pcpa@gnu.org>
1011
1012 * lib/jit_names.c: New file with single definition of string
1013 representation of lightning IR codes.
1014
1015 * size.c: Modified to append the code name in a C comment
1016 after the maximum instruction size.
1017
1018 * lib/jit_print.c: Minor change to not duplicate jit_names.c
1019 contents.
1020
1021 * lib/jit_aarch64-sz.c, lib/jit_alpha-sz.c, lib/jit_arm-sz.c,
1022 lib/jit_hppa-sz.c, lib/jit_ia64-sz.c, lib/jit_mips-sz.c,
1023 lib/jit_ppc-sz.c, lib/jit_s390x-sz.c, lib/jit_sparc-sz.c,
1024 lib/jit_x86-sz.c: Rewritten to add string representation of
1025 IR codes in a C comment.
1026
10272014-10-14 Paulo Andrade <pcpa@gnu.org>
1028
1029 * lib/jit_aarch64-cpu.c, lib/jit_alpha-cpu.c, lib/jit_arm-cpu.c,
1030 lib/jit_hppa-cpu.c, lib/jit_mips-cpu.c, lib/jit_ppc-cpu.c,
1031 lib/jit_sparc-cpu.c: Implement or correct the internal
1032 nop(count) call that receives an argument that tells the
1033 modulo bytes to align the code for the next instruction.
1034
1035 * include/lightning.h, lib/lightning.c, lib/jit_aarch64.c,
1036 lib/jit_alpha.c, lib/jit_arm.c, lib/jit_hppa.c, lib/jit_ia64.c,
1037 lib/jit_mips.c, lib/jit_ppc.c, lib/jit_s390x.c, lib/jit_sparc.c,
1038 lib/jit_x86.c: Implement the new jit_align() call that receive
1039 an argument, that tells the modulo, in bytes, to align the
1040 next instruction. In most backends the only value that makes
1041 a difference is a value that matches sizeof(void*), as all
1042 other values usually are already automatically aligned in
1043 labels, but not guaranteed to be aligned at word size bytes.
1044
1045 * check/align.ok, check/align.tst: New files, implementing
1046 a simple test for the new jit_align() interface.
1047
1048 * check/Makefile.am, check/lightning.c, lib/jit_aarch64-sz.c,
1049 lib/jit_alpha-sz.c, lib/jit_arm-sz.c, lib/jit_hppa-sz.c,
1050 lib/jit_ia64-sz.c, lib/jit_mips-sz.c, lib/jit_ppc-sz.c,
1051 lib/jit_print.c, lib/jit_s390x-sz.c, lib/jit_sparc-sz.c,
1052 lib/jit_x86-sz.c: Update for the new jit_code_align code and
1053 the jit_align() interface.
1054
10552014-10-13 Paulo Andrade <pcpa@gnu.org>
1056
1057 * include/lightning.h, lib/jit_size.c, size.c: Use a
1058 symbolic value for the last IR code.
1059
10602014-10-12 Paulo Andrade <pcpa@gnu.org>
1061
1062 * include/lightning.h, include/lightning/jit_private.h,
1063 lib/jit_aarch64-cpu.c, lib/jit_alpha-cpu.c, lib/jit_arm-cpu.c,
1064 lib/jit_hppa-cpu.c, lib/jit_ia64-cpu.c, lib/jit_mips-cpu.c,
1065 lib/jit_ppc-cpu.c, lib/jit_s390x-cpu.c, lib/jit_sparc-cpu.c,
1066 lib/jit_x86-cpu.c, lib/lightning.c: Implement the new
1067 jit_frame and jit_tramp interfaces, that allow writing
1068 trampoline like calls, where a single dispatcher jit buffer
1069 is written, and later other jit buffers are created, with
1070 the same stack frame layout as the dispatcher. This is the
1071 logic that GNU Smalltalk used in lightning 1.x, and is required
1072 to make a sane port for lighting 2.x.
1073
1074 * jit_ia64-cpu.c: Implement support for jit_frame and jit_tramp,
1075 and also correct wrong encoding for B4 instructions, that
1076 implement jmpr, as well as correct reverse logic in _jmpr,
1077 that was moving the branch register to the jump register,
1078 and not vice-versa.
1079 Also, if a stack frame is to be assumed, always assume it may
1080 call a function with up to 8 arguments, regardless of the
1081 hint frame argument.
1082
1083 * lib/jit_arm.c: Add a new must_align_p() interface to ensure
1084 function prologs are always aligned. This condition was
1085 previously always true, somewhat by accident, but with
1086 jit_tramp it is not guaranteed.
1087
1088 * jit_ia64-cpu.c: lib/jit_ppc.c: Add minor special handling
1089 required to implement jit_tramp, where a function descriptor
1090 should not be added before a prolog, as jit_tramp means omit
1091 prolog.
1092
1093 * check/lightning.c: Update test driver for the new interfaces.
1094
1095 * check/Makefile.am, check/tramp.tst, check/tramp.ok: Add
1096 a simple test and example of the jit_frame and jit_tramp
1097 usage implementing a simple Fibonacci function using a
1098 simulation of an interpreter stack and how it would handle
1099 state in language specific variables.
1100
1101 * doc/body.texi: Add documentation for jit_frame and
1102 jit_tramp.
1103
11042014-09-29 Paulo Andrade <pcpa@gnu.org>
1105
1106 * lib/jit_aarch64.c, lib/jit_alpha.c, lib/jit_arm.c,
1107 lib/jit_hppa.c, lib/jit_ia64.c, lib/jit_mips.c,
1108 lib/jit_ppc.c, lib/jit_s390x.c, lib/jit_sparc.c,
1109 lib/jit_x86.c, lib/lightning.c: Allow jit_jmpi on a
1110 target that is not a node. This may lead to hard to
1111 debug code generation, but is a required feature for
1112 certain generators, like the ones that used lightning
1113 1.2x. Note that previously, but not really well
1114 documented, it was instructed to use:
1115 jit_movi(rn, addr); jit_jmpr(rn);
1116 but now, plain:
1117 jit_patch_abs(jit_jmpi(), addr);
1118 should also work.
1119
11202014-09-24 Paulo Andrade <pcpa@gnu.org>
1121
1122 * lib/jit_x86-sz.c: Generate information about instruction
1123 lengths for more precise calculation of buffer size on
1124 Windows x64. This change is specially important because
1125 the maximum instruction length is larger than other
1126 systems, what could cause an out of bounds write on
1127 special conditions without this update.
1128
11292014-09-24 Paulo Andrade <pcpa@gnu.org>
1130
1131 * check/lightning.c: Add workaround to conflicting global
1132 optind variable in cygwin binutils that have an internal
1133 getopt* implementation.
1134
1135 * lib/jit_x86-cpu.c: Add a simple define ffsl ffs if building
1136 for 32 bit and there is no ffsl function.
1137
11382014-09-24 Paulo Andrade <pcpa@gnu.org>
1139
1140 * check/lightning.c: Add a hopefully temporary kludge to not use
1141 sprintf and sscanf returned by dlsym. This is required to pass
1142 the varargs test.
1143
1144 * include/lightning/jit_private.h: Use symbolic name for first
1145 integer register argument, as this is different in sysv and
1146 win64 abi.
1147
1148 * include/lightning/jit_x86.h: Add conditionals and definitions
1149 for Windows x64 (under __CYGWIN__ preprocessor conditional).
1150
1151 * lib/jit_x86-cpu.c: Correct one instruction encoding bug, that
1152 was working by accident. Only use rax to rdx for some byte
1153 operations to work on compatibility mode (that is, to generate
1154 the proper encoding, instead of actually generating encoding
1155 for high byte registers, e.g. %bh).
1156 Add proper prolog and epilog for windows x64.
1157
1158 * lib/jit_x86-sse.c: Correct a swapped rex prefix for float
1159 operations.
1160
1161 * lib/jit_x86.c: Adjust to support Windows x64 abi.
1162
1163 * check/check.x87.nodata.sh: New file, previously used but that
1164 was missing git.
1165
11662014-09-07 Paulo Andrade <pcpa@gnu.org>
1167
1168 * lib/lightning.c: Mark all registers advertised as live, as
1169 per jit_callee_save_p as live whenever reaching a jump that
1170 cannot be tracked. This is a rethink of the previous commit,
1171 and is a better approach, otherwise there would not be much
1172 sense on relying on jit_callee_save_p if it could not be
1173 trusted.
1174
1175 * check/jmpr.tst, check/jmpr.ok: New files implementing a very
1176 simple test case, that would actually cause an assertion on
1177 code before the change to only mark as live when reaching a
1178 jump that could not tracked, the actually advertised as callee
1179 save registers.
1180
1181 check/Makefile.am: Update for new jmpr test case.
1182
11832014-09-01 Paulo Andrade <pcpa@gnu.org>
1184
1185 * lib/lightning.c: Do not mark all registers in unknown state
1186 as live on jit_jmpr, or jit_jmpi to an absolute address. Instead,
1187 treat it as a function call, and only consider JIT_Vn registers
1188 as possibly live.
1189
11902014-08-29 Paulo Andrade <pcpa@gnu.org>
1191
1192 * doc/body.texi: Add a proper info menu entry for
1193 GNU lightning.
1194
1195 * doc/version.texi: Regenerate.
1196
11972014-08-16 Paulo Andrade <pcpa@gnu.org>
1198
1199 * lib/jit_aarch64-cpu.c, lib/jit_aarch64-fpu.c,

1201 lib/jit_hppa-cpu.c, lib/jit_hppa-fpu.c,

1207 lib/jit_x86-cpu.c, lib/jit_x86-sse.c,
1208 lib/jit_x86-x87.c: Review generation of all branch
1209 instructions and always adds the jit_class_nospill
1210 bitfield for temporary registers that cannot be spilled
1211 because the reload would be after a conditional jump; the
1212 patch only adds an extra assertion. These conditions do
1213 not happen on documented lightning usage, but can happen
1214 if one uses the not exported jit_get_reg and jit_unget_reg
1215 calls and cause enough register starvation.
1216
12172014-08-16 Paulo Andrade <pcpa@gnu.org>
1218
1219 * lib/jit_alpha.c: Correct wrong bitmask of most argument
1220 float register arguments, that were being set as callee
1221 save instead of argument registers class.
1222
12232014-08-16 Paulo Andrade <pcpa@gnu.org>
1224
1225 * lib/jit_arm-sz.c: Regenerate table of known maximum
1226 instruction sizes for the software float fallback,
1227 that implements "virtual" float registers in the stack
1228 and operations as calls to libgcc.
1229
1230 * size.c: Correct typo in the generated jit_arm-sz.c file.
1231
12322014-08-10 Paulo Andrade <pcpa@gnu.org>
1233
1234 * include/lightning/jit_alpha.h, lib/jit_alpha-cpu.c,
1235 lib/jit_alpha-fpu.c, lib/jit_alpha-sz.c, lib/jit_alpha.c:
1236 New files implementing a lightning Alpha port. Thanks
1237 to Trent Nelson and snakebit.net staff for providing access
1238 to an Alpha system.
1239
1240 * check/float.tst, check/lightning.c, configure.ac,
1241 include/lightning.h, include/lightning/Makefile.am,
1242 include/lightning/jit_private.h, lib/Makefile.am,
1243 lib/jit_disasm.c, lib/jit_size.c, lib/lightning.c:
1244 Minor changes to adapt for the new Alpha port.
1245
12462014-08-10 Paulo Andrade <pcpa@gnu.org>
1247
1248 * lib/lightning.c: Always mark JIT_RET and JIT_FRET as
1249 live in a function epilog. This is required because
1250 on some ports a complex sequence, allocating one or more
1251 registers, may be required to jump from a ret* to the
1252 epilog, and the lightning api does not have annotations
1253 to know if a function returns a value, or the type of
1254 the return value.
1255
12562014-08-10 Paulo Andrade <pcpa@gnu.org>
1257
1258 * lib/lightning.c: Change the correct live bitmask of
1259 return registers after a function call in jit_update.
1260
12612014-08-10 Paulo Andrade <pcpa@gnu.org>
1262
1263 * lib/lightning.c: Change assertions to have an int
1264 result and correct a bad bit mask assertion.
1265
12662014-08-10 Paulo Andrade <pcpa@gnu.org>
1267
1268 * lib/jit_aarch64.c: Correct bad setup for assertion
1269 of consistency before a patch.
1270
12712014-08-10 Paulo Andrade <pcpa@gnu.org>
1272
1273 * lib/jit_mips-cpu.c: Correct typo in the jit_bmsr
1274 implementation that was using the wrong test result
1275 register.
1276
12772014-07-28 Paulo Andrade <pcpa@gnu.org>
1278
1279 * lib/jit_memory.c: Do not call free on NULL pointers.
1280
1281 * include/lightning/jit_private.h, lib/jit_note.c,
1282 lib/lightning.c: Add a wrapper to memcpy and memmove
1283 to not actually call those functions with a zero size
1284 argument, and likely also a null src or dst.
1285
12862014-07-27 Paulo Andrade <pcpa@gnu.org>
1287
1288 * include/lightning/jit_private.h, lib/jit_disasm.c,
1289 lib/lightning.c: Remove the global jit_progname variable.
1290 It was being only used in jit_init_debug, that is called
1291 from init_jit, so, just pass an argument.
1292
12932014-07-27 Paulo Andrade <pcpa@gnu.org>
1294
1295 * doc/body.texi: Add note that jit_set_memory_functions
1296 should be called before init_jit, because init_jit
1297 itself may call the memory wrappers.
1298
12992014-04-22 Paulo Andrade <pcpa@gnu.org>
1300
1301 * lib/jit_arm.c: Do not get confused with default settings
1302 if /proc is not mounted on Linux specific code path.
1303
13042014-04-09 Paulo Andrade <pcpa@gnu.org>

1311 Do not add jit_regset_t, JIT_RA0, and JIT_FA0 to the installed
1312 header file. These types and definitions are supposed to be
1313 only used internally.
1314
13152014-04-05 Paulo Andrade <pcpa@gnu.org>
1316
1317 * lib/jit_arm-cpu.c: Only adjust stack pointer in prolog if
1318 need stack space, that is, do not emit a nop instruction
1319 subtracting zero from the stack pointer.
1320
13212014-04-04 Paulo Andrade <pcpa@gnu.org>
1322
1323 * lib/jit_disasm.c: Correct a crash in the doc/printf example
1324 on arm due to releasing the data_info information in
1325 jit_clear_state. This is a special case for arm only, and
1326 actually, only armv5 or older uses the data_info buffer,
1327 or when forcing arm instruction set mode besides thumb
1328 available.
1329
13302014-12-03 Paulo Andrade <pcpa@gnu.org>
1331
1332 * doc/body.texi: Write detailed description and examples for
1333 jit_get_memory_functions, jit_set_memory_functions,
1334 jit_get_code, jit_set_code, jit_get_data and jit_set_data.
1335
13362014-12-03 Paulo Andrade <pcpa@gnu.org>
1337
1338 * include/lightning.h, include/lightning/jit_private.h,
1339 lib/lightning.c: Implement the new jit_set_data() interface,
1340 and the new jit_get_data() helper. Like jit_set_code(),
1341 jit_realize() should be called before jit_set_data().
1342 The most common usage should be jit_set_data(JIT_DISABLE_DATA
1343 | JIT_DISABLE_NOTE), to force synthesize any float/double
1344 constant in the stack and not generate any debug information.
1345
1346 * lib/jit_note.c: Minor change to debug note generation as
1347 now it uses an alternate temporary data buffer during constants
1348 and debug generation to accommodate the possibility of the user
1349 setting an alternate data buffer.
1350
1351 * lib/jit_hppa-fpu.c, lib/jit_s390x.c, lib/jit_s390x-cpu.c,
1352 lib/jit_s390x-fpu.c, lib/jit_sparc.c, lib/jit_sparc-fpu.c,
1353 lib/jit_x86-sse.c, lib/jit_x86-x87.c: Implement jit_set_data.
1354
1355 * lib/jit_hppa-sz.c, lib/jit_sparc-sz.c, lib/jit_x86-sz.c,
1356 lib/jit_s390x-sz.c: Update for several instructions that now
1357 have a different maximum length due to jit_set_data.
1358
1359 * lib/jit_mips-fpu.c: Implement jit_set_data, but missing
1360 validation on n32 and n64 abis (and/or big endian).
1361
1362 * lib/jit_mips-sz.c: Update for changes in o32.
1363
1364 * lib/jit_ppc-fpu.c: Implement jit_set_data, but missing
1365 validation on Darwin PPC.
1366
1367 * lib/jit_ppc-sz.c: Update for changes in powerpc 32 and
1368 64 bit.
1369
1370 * lib/jit_ia64-fpu.c: Implement untested jit_set_data.
1371
1372 * TODO: Add note to list ports that were not tested for the
1373 new jit_set_data() feature, due to no longer having access
1374 to them.
1375
1376 * check/nodata.c: New file implementing a simple test exercising
1377 several different conditions created by jit_set_data().
1378
1379 * check/check.nodata.sh: New file implementing a wrapper
1380 over the existing *.tst files, that runs all tests without
1381 using a data buffer for constants; only meaningful (and
1382 enabled) on architectures that used to store float/double
1383 constants on a read only data buffer.
1384
1385 * configure.ac, check/Makefile.am: Update for the new test
1386 cases.
1387
1388 * check/lightning.c: Implement the new "-d" option that
1389 sets an internal flag to call jit_set_data() disable
1390 constants and debug, that is, using only a pure code
1391 buffer.
1392
13932014-11-03 Paulo Andrade <pcpa@gnu.org>
1394
1395 * include/lightning.h, include/lightning/jit_private.h,
1396 lib/lightning.c: Implement the new jit_set_code() interface,
1397 that allows instructing lightning to use an alternate code
1398 buffer. The new jit_realize() function should be called
1399 before jit_set_code(), and usually call jit_get_code()
1400 to query the amount of bytes expected to be required for
1401 the code.
1402
1403 * lib/jit_size.c: Minor update to have less chances of
1404 miscalculating the code buffer by starting the counter
1405 with the size of the longest instruction instead of zero,
1406 as code emit fails if at any moment less than the longest
1407 instruction bytes are available.
1408
1409 * check/setcode.c: New file implementing some basic tests
1410 of the new jit_set_code() interface.
1411
1412 * check/Makefile.am: Update for newer test case.
1413
14142014-06-03 Paulo Andrade <pcpa@gnu.org>
1415
1416 * include/lightning.h, lib/lightning.c: Add the new
1417 jit_indirect() call, that returns a special label node,
1418 and tells lightning that the label may be the target of
1419 an indirect jump.
1420
1421 * doc/body.texi: Document the new jit_indirect() call, and
1422 add examples of different ways to create labels and branches.
1423
14242014-23-02 Paulo Andrade <pcpa@gnu.org>
1425
1426 * lib/jit_x86.c: Rewrite previous patch to inline save/restore
1427 because clobbering %ebx in x86 is treated as an error
1428 (jit_x86.c:239:5: error: PIC register clobbered by 'ebx' in 'asm').
1429
14302014-19-02 Paulo Andrade <pcpa@gnu.org>
1431
1432 * lib/jit_x86.c: Rewrite incorrect inline assembly that could
1433 truncate a variable in a callee save register. Now it simply
1434 tells gcc that the register is clobbered, instead of using a
1435 *32 bit* swap with a temporary variable. The problem only
1436 happens when compiling with optimization.
1437
14382014-19-02 Paulo Andrade <pcpa@gnu.org>
1439
1440 * include/lightning/jit_aarch64.h, include/lightning/jit_arm.h,
1441 include/lightning/jit_hppa.h, include/lightning/jit_ia64.h,
1442 include/lightning/jit_mips.h, include/lightning/jit_ppc.h,
1443 include/lightning/jit_s390x.h, include/lightning/jit_sparc.h,
1444 include/lightning/jit_x86.h: Change jit_regset_t to an
1445 unsigned type, to allow safe right shift.
1446
1447 * lib/lightning.c: Rewrite jit_regset_scan1 to allow easier
1448 compiler optimization.
1449
14502013-12-03 Paulo Andrade <pcpa@gnu.org>
1451
1452 * lib/jit_x86-x87.c: Correct wrong optimization when
1453 loading the log(2) constant.
1454
14552013-12-03 Paulo Andrade <pcpa@gnu.org>
1456
1457 * lib/jit_x86-cpu.c: Use the emms instruction before
1458 calling any function. This is particularly important
1459 when using c99 complex functions as it can easily
1460 overflow the x87 stack due to the way lightning uses
1461 the x87 stack as a flat register file.
1462
14632013-12-02 Paulo Andrade <pcpa@gnu.org>
1464
1465 * lib/jit_x86-x87.c: Correct wrong code generation due
1466 to comparing the base and not the value register with
1467 %st(0) in stxi_f.
1468
14692013-12-02 Paulo Andrade <pcpa@gnu.org>
1470
1471 * lib/jit_x86-x87.c, lib/jit_x86.c: Use 8 bytes aligned
1472 stack offset for float/double x87 to/from sse move.
1473
14742013-11-27 Paulo Andrade <pcpa@gnu.org>
1475
1476 * configure.ac, lib/jit_arm-swf.c, lib/jit_arm.c: Add
1477 changes that should at least allow building lightning
1478 on Apple iOS7.
1479
14802013-10-08 Paulo Andrade <pcpa@gnu.org>
1481
1482 * lib/jit_ppc-cpu.c: Correct wrong shortcut for ldxi_l with
1483 a zero offset, that was calling ldr_i instead of ldr_l.
1484
14852013-10-08 Paulo Andrade <pcpa@gnu.org>
1486
1487 * include/lightning/jit_arm.h, lib/jit_arm-cpu.c: Do not use
1488 by default load/store instructions that map to ldrt/strt.
1489 There is already the long displacement version for positive
1490 offsets, and when using a (shorter) negative offset it does
1491 not map to ldrt/strt. At least on qemu strt may cause
1492 reproducible, but unexpected SIGILL.
1493
14942013-10-08 Paulo Andrade <pcpa@gnu.org>
1495
1496 * lib/jit_arm-vfp.c: Correct wrong load/store offset
1497 calculation when the displacement is constant but too
1498 large to use an instruction with an immediate offset.
1499
15002013-10-07 Paulo Andrade <pcpa@gnu.org>
1501
1502 * check/self.c: Extend tests to validate jit_callee_save_p
1503 does not cause an assertion on valid arguments, and test
1504 extra registers defined on some backends.
1505
1506 * configure.ac: Do not ignore environment CFLAGS when
1507 checking if need to test runtime configurable options,
1508 like use x87 when sse2 is available, arm instruction set
1509 instead of thumb, etc.
1510
1511 * include/lightning/jit_arm.h: Correct wrong jit_f macro
1512 definition.
1513
519a9ea1 1514 * include/lightning/jit_ia64.h, include/lightning/jit_ppc.h:
4a71579b
PC
1515 Correct wrong jit_r macro definition.
1516
1517 * lib/jit_x86-x87.c, lib/jit_x86.c: Actually use the
1518 reserved stack space for integer to/from float conversion.
1519 The stack space was also changed to ensure it is 8 bytes
1520 aligned. Also, for Solaris x86 in 32 bit mode, an alternate
1521 truncr_d was implemented because for some reason it is
1522 failing with SIGILL if using the "fisttpl" instructions,
1523 that must be available on p6 or newer, but for the sake of
1524 making all tests pass, implement a 486 or newer sequence
1525 if "sun" is defined.
1526
15272013-10-03 Paulo Andrade <pcpa@gnu.org>
1528
1529 * include/lightning/jit_mips.h, lib/jit_mips-cpu.c,
1530 lib/jit_mips-sz.c, lib/jit_mips.c, size: Build and
1531 pass all test cases on Irix big endian mips using
1532 the 64 bit abi.
1533
15342013-10-02 Paulo Andrade <pcpa@gnu.org>
1535
1536 * include/lightning/jit_mips.h: Add proper mips abi detection.
1537
15382013-09-30 Paulo Andrade <pcpa@gnu.org>
1539
1540 * lib/jit_print.c: Do not crash if calling jit_print from
1541 gdb before actually emitting code.
1542
1543 * lib/lightning.c: Correct misplaced check for already
1544 visited blocks on conditional branches, what was preventing
1545 proper merge live bit masks of forward blocks.
1546
15472013-09-30 Paulo Andrade <pcpa@gnu.org>
1548
1549 * lib/jit_x86-cpu.c: Correct not properly tested case of using
1550 %r12 as index register, what was causing an invalid assertion.
1551 %r12 is mapped to the "extra" JIT_R3 register, and test cases
1552 only test "standard" lightning registers.
1553
15542013-09-28 Paulo Andrade <pcpa@gnu.org>
1555
1556 * lib/jit_ia64.c: Minor change to force collecting the maximum
1557 instruction length in the --enable-devel-get-jit-size build
1558 mode. The actual generated file did not change because the
1559 sampling was large enough that it had already collected proper
1560 information in the previously slightly buggy code (not forcing
1561 a sync of the instructions that could be combined).
1562
15632013-09-27 Paulo Andrade <pcpa@gnu.org>
1564
1565 * lib/jit_arm.c: Correct build when disassembler is
1566 disabled.
1567
15682013-09-25 Paulo Andrade <pcpa@gnu.org>
1569
1570 * lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c: Correct some
1571 off by one range checks (that were only accepting values
1572 one less than the maximum allowed) and an invalid test
1573 condition check that was forcing it to always use
1574 indirect jumps even when reachable with an immediate
1575 displacement.
1576
15772013-09-24 Paulo Andrade <pcpa@gnu.org>
1578
1579 * lib/jit_aarch64-sz.c, lib/jit_arm-sz.c, lib/jit_hppa-sz.c,
1580 lib/jit_ia64-sz.c, lib/jit_mips-sz.c, lib/jit_ppc-sz.c,
1581 lib/jit_s390x-sz.c, lib/jit_size.c, lib/jit_sparc-sz.c,
1582 lib/jit_x86-sz.c: New files implementing static tables
1583 with longest known instructions length generated to match
1584 a lightning instruction. These tables should make it easier
1585 to make it very unlikely to ever miscalculate, or by too
1586 much, the size of a code buffer.
1587
1588 * lib/jit_size.c: New file that aids to either collect
1589 jit code size information, or use the information depending
1590 on build options.
1591
1592 * size.c: New helper file that parses input for, and create
1593 an initial jit_$arch-sz.c file, that needs some minor edit
1594 for arches with multiple configurations.
1595
1596 * configure.ac, Makefile.am: Add the new, devel mode only
1597 --enable-devel-get-jit-size configure option, that sets
1598 compile time flags to collect jit code size information,
1599 that will be used as input for the "noinst size program".
1600
1601 * lib/jit_aarch64.c, lib/jit_arm.c, lib/jit_disasm.c,
1602 lib/jit_hppa.c, lib/jit_ia64.c, lib/jit_memory.c,
1603 lib/jit_mips.c, lib/jit_ppc.c, lib/jit_s390x.c,
1604 lib/jit_sparc.c, lib/jit_x86.c, lib/lightning.c: Minor
1605 changes for the --enable-devel-get-jit-size build mode,
1606 as well as the "production build mode" with jit code
1607 size information.
1608
16092013-09-14 Paulo Andrade <pcpa@gnu.org>
1610
1611 * include/lightning.h, lib/lightning.c: Add the new
1612 jit_pointer_p interface, that returns a boolean value
1613 telling if the pointer argument is inside the jit
1614 code buffer. This is useful to avoid the need to add
1615 extra labels and calls to jit_address to figure bounds
1616 of code buffer, and still keep internal data private.
1617
16182013-09-13 Paulo Andrade <pcpa@gnu.org>
1619
1620 * include/lightning.h, include/lightning/jit_private.h,
1621 lib/jit_note.c: Change the code argument of jit_get_note
1622 to a jit_pointer_t and make jit_get_note a public interface.
1623 It was intended so since start, as a way to map an offset
1624 in the code to a function name, file name and line number
1625 mapping.
1626
16272013-09-11 Paulo Andrade <pcpa@gnu.org>
1628
1629 * doc/body.texi: Correct reversed arguments in example of
1630 usage in a (possibly) multi threaded, multiple jit_state_t
1631 environments.
1632
1633 * include/lightning/jit_arm.h, include/lightning/jit_private.h,
1634 lib/jit_arm-cpu.c, lib/jit_arm.c: Make a previously, non
1635 documented, global state private to the related jit_state_t
1636 generating code.
1637
16382013-09-10 Paulo Andrade <pcpa@gnu.org>
1639
1640 * check/self.c, check/self.ok: New files implementing simple
1641 consistency check assertions. At first validating some macros
1642 that use values from different sources agree.
1643
1644 * check/Makefile.am: Update for the new test case.
1645
1646 * include/lightning.h, lib/lightning.c: Add the new
1647 jit_callee_save_p() call, that is intended to be used when
1648 writing complex code using lightning, so that one does not
1649 need to verify what backend is being used, or have access to
1650 private data, to query if a register is callee save or not;
1651 on several backends the scratch registers are actually callee
1652 save.
1653
1654 * include/lightning/jit_aarch64.h, include/lightning/jit_arm.h,
1655 include/lightning/jit_hppa.h, include/lightning/jit_mips.h,
1656 include/lightning/jit_ppc.h, include/lightning/jit_sparc.h,
1657 include/lightning/jit_x86.h: Add an explicit definition for
1658 JIT_R3-JIT_Rn, JIT_V3-JIT_Vn and JIT_F6-JIT_Fn when applicable.
1659 This allows one to write code based on "#if defined(JIT_XN)"
1660 and therefore, not need to check what is the current backend
1661 or have access to private data structures. This is particularly
1662 useful when writing virtual machines with several specialized,
1663 global registers.
1664
1665 * lib/jit_ia64.c: Properly flag the callee save general
1666 purpose registers as such, so that jit_callee_save_p() works
1667 as intended.
1668
16692013-09-10 Paulo Andrade <pcpa@gnu.org>
1670
1671 * check/lightning.c, configure.ac: Conditionally use the
1672 code written to workaround a bug in the Hercules emulator,
1673 as isnan and isinf are not available at least on HP-UX ia64.
1674
16752013-09-10 Paulo Andrade <pcpa@gnu.org>
1676
1677 * lib/jit_s390x-cpu.c: Spill/reload correct callee save
1678 float registers.
1679
16802013-09-10 Paulo Andrade <pcpa@gnu.org>
1681
1682 * lib/jit_hppa-cpu.c: Correct code to call a function stored
1683 in a register or a patched function address.
1684
16852013-09-10 Paulo Andrade <pcpa@gnu.org>
1686
1687 * lib/jit_ia64-cpu.c: Correct incorrect logic when restoring
1688 the value of the "r2" callee save register.
1689
16902013-08-29 Paulo Andrade <pcpa@gnu.org>
1691
1692 * lib/jit_arm-cpu.c, lib/jit_arm.c: Correct wrong test and update
1693 of the thumb offset information, when checking if needing to
1694 patch a jump from arm to thumb mode. The problem would happen when
1695 remapping the code buffer, and the new address being lower than
1696 the previous one.
1697
16982013-08-26 Paulo Andrade <pcpa@gnu.org>
1699
1700 * configure.ac: Extend FreeBSD test to also handle NetBSD.
1701
1702 * lib/jit_x86-cpu.c: Correct wrongly defined offset type of
1703 ldxi_ui. Problem detected when building on NetBSD.
1704
1705 * lib/lightning.c: Adjust code to handle NetBSD mremap,
1706 where arguments do not match Linux mremap.
1707
17082013-08-26 Paulo Andrade <pcpa@gnu.org>
1709
1710 * lib/jit_ppc.c: Correct C sequence point problem miscalculating
1711 the actual function address in a function descriptor. Problem
1712 happens with gcc 4.8.1 at least.
1713
17142013-08-11 Paulo Andrade <pcpa@gnu.org>
1715
1716 * lib/jit_s390x-cpu.c: Correct code checking if immediate
1717 fits instruction, but using the negated value.
1718
17192013-07-28 Paulo Andrade <pcpa@gnu.org>
1720
1721 * include/lightning/jit_s390x.h, lib/jit_s390x-cpu.c,
1722 lib/jit_s390x-fpu.c, lib/jit_s390x.c: New files
1723 implementing the new s390x port.
1724
1725 * configure.ac, include/lightning.h,
1726 include/lightning/Makefile.am,
1727 include/lightning/jit_private.h,
1728 lib/Makefile.am, lib/jit_disasm.c, lib/lightning.c:
1729 Minor adaptation for the new s390x backend.
1730
1731 * check/float.tst: Update for the s390x result of
1732 truncating +Inf to integer.
1733
1734 * check/qalu_mul.tst: Add extra test cases to better test
1735 high word of signed multiplication as the result is
1736 adjust from unsigned multiplication on s390x.
1737
17382013-07-28 Paulo Andrade <pcpa@gnu.org>
1739
1740 * check/lightning.c: Do not assume casting a double NaN or
1741 Inf to float will produce the expected float NaN or Inf.
1742 This is not true at least under s390x.
1743
17442013-07-28 Paulo Andrade <pcpa@gnu.org>
1745
1746 * check/check.arm.sh, check/check.sh, check/check.swf.sh,
1747 check/check.x87.sh: Properly check test programs output,
1748 not just rely on the test program self testing the results
1749 and not crashing.
1750
17512013-07-28 Paulo Andrade <pcpa@gnu.org>
1752
1753 * lib/jit_aarch64.c: Remove unused macros left from cut&paste
1754 of jit_arm.c.
1755
17562013-07-16 Paulo Andrade <pcpa@gnu.org>
1757
1758 * include/lightning/jit_aarch64.h, lib/jit_aarch64-cpu.c,
1759 lib/jit_aarch64-fpu.c, lib/jit_aarch64.c: New files
1760 implementing the new aarch64 port, as a new architecture,
1761 not as an expansion of the existing armv[4-7] port.
1762
1763 * check/lightning.c: Add aarch64 support and a small
1764 change to recognize character constants as immediate
1765 values.
1766
1767 * check/float.tst: Add aarch64 preprocessor conditionals
1768 to select proper expected value when converting [+-]Inf
1769 and NaN to integer.
1770
1771 * include/lightning/jit_arm.h, lib/jit_arm.c: Minor changes
1772 to better match the new aarch64 files.
1773
1774 * configure.ac, include/lightning.h,
1775 include/lightning/Makefile.am, include/lightning/jit_private.h,
1776 lib/Makefile.am, lib/lightning.c: Minor adjustments
1777 for the aarch64 port.
1778
17792013-07-08 Paulo Andrade <pcpa@gnu.org>
1780
1781 * NEWS, THANKS, configure.ac, doc/version.texi: Update for
1782 the 1.99a second alpha release.
1783
17842013-06-25 Paulo Andrade <pcpa@gnu.org>
1785
1786 * lib/jit_mips.c: Correct cut&paste error that caused wrong
1787 stack offset calculation for double arguments in stack in
1788 the o32 abi.
1789 Correct typo in the __LITTLE_ENDIAN macro name, that came
1790 from cut&paste error in the original typo in lib/jit_ppc.c.
1791
1792 * lib/jit_ia64.c, lib/jit_ppc.c: Correct typo in the
1793 __LITTLE_ENDIAN macro name.
1794
17952013-06-22 Paulo Andrade <pcpa@gnu.org>
1796
1797 * check/lightning.c, configure.ac, include/lightning.h,
1798 lib/lightning.c: Add tests and quirks to build/detect
1799 and/or work on Irix.
1800
1801 * include/lightning/jit_mips.h, lib/jit_mips-cpu.c,
1802 lib/jit_mips-fpu.c, lib/jit_mips.c: Adapt code to run
1803 in big endian mips, using the n32 abi.
1804
18052013-06-18 Paulo Andrade <pcpa@gnu.org>
1806
1807 * include/lightning.h: Minor extra preprocessor testing
1808 to "detect" byte order on x86 solaris, that now builds
1809 and pass all test cases.
1810
18112013-06-18 Paulo Andrade <pcpa@gnu.org>
1812
1813 * lib/jit_sparc-cpu.c: Correct compiler warning of value
1814 used before assignment. The usage is bogus as the api
1815 requires always patching jumps, but the random value used
1816 could cause an assertion due to invalid displacement.
1817
1818 * lib/jit_sparc.c: Always load and store double arguments
1819 in stack as 2 float loads or stores, for safety, as unaligned
1820 access is not allowed in Sparc Solaris.
1821
18222013-06-14 Paulo Andrade <pcpa@gnu.org>
1823
1824 * configure.ac: Force -mlp64 to CFLAGS on HP-UX ia64 port.
1825 It is the only supported mode, and expects gcc as C compiler.
1826
1827 * include/lightning.h, lib/jit_ia64-cpu.c, lib/jit_ia64.c:
1828 Correct ia64 port to work on HP-UX that runs it in big endian
1829 mode.
1830
18312013-06-10 Paulo Andrade <pcpa@gnu.org>
1832
1833 * lib/jit_hppa.c: Sanitize the cache synchronization inline
1834 assembly code that was doing twice the work and redundantly
1835 flushing the end address every loop iteration.
1836
18372013-06-09 Paulo Andrade <pcpa@gnu.org>
1838
1839 * configure.ac, check/Makefile.am, doc/Makefile.am: Do not
1840 explicitly link to -ldl, but instead autodetect the library
1841 with dlopen, dlsym, etc.
1842
1843 * check/lightning.c: Add workaround to apparently buggy
1844 getopt in HP-UX that sets optind to the wrong index, and
1845 use RTLD_NEXT on HP-UX instead of RTLD_DEFAULT to dlsym
1846 global symbols.
1847
1848 * include/lightning.h: Rework definitions of wordsize and
1849 byte order to detect proper values on HP-UX.
1850
1851 * lib/lightning.c: Minor correction to use MAP_ANONYMOUS
1852 instead of MAP_ANON on HP-UX.
1853
1854 * lib/jit_hppa.c: Float arguments must be passed on integer
1855 registers on HP-UX, not only for varargs functions.
1856 Add code to properly clear instruction cache. This was
1857 not required on Debian hppa port, but may have been working
1858 by accident.
1859
1860 * lib/jit_hppa-cpu.c: Follow pattern of HP-UX binaries and
1861 use bve,n instead of bv,n to return from functions.
1862
1863 * lib/jit_hppa-fpu.c: For some reason "fst? frX,rX,(rY)" did
1864 not work on the tested computer (HP-UX B.11.23 U 9000/785 HP-UX)
1865 so the code was changed, at first for __hpux only to add the
1866 base and offset register and use the instruction with an
1867 immediate (zero) offset.
1868
18692013-06-07 Paulo Andrade <pcpa@gnu.org>
1870
1871 * check/lightning.c, lib/jit_disasm.c, lib/jit_ppc-cpu.c,
1872 lib/jit_ppc-fpu.c, lib/jit_ppc.c, include/lightning.h,
1873 include/lightning/jit_ppc.h, include/lightning/jit_private.h:
1874 Adapt code to work on 32 bit AIX ppc using gcc. Most changes
1875 are basically to adapt the elf64 logic to 32 bit, as it does
1876 not use the same convention of 32 bit Darwin ppc.
1877
1878 * check/stack.tst: Add a fake memcpy function to the test
1879 case if running under AIX, as it is not available to dlsym.
1880
1881 * configure.ac: Check for getopt.h header, not available in
1882 AIX.
1883
18842013-06-01 Paulo Andrade <pcpa@gnu.org>
1885
1886 * include/lightning/jit_hppa.h, lib/jit_hppa-cpu.c,
1887 lib/jit_hppa-fpu.c, lib/jit_hppa.c: New files implementing
1888 the hppa port. Built on Debian Linux PA-RISC 2.0, 32 bit.
1889
1890 * check/float.tst: Add preprocessor for hppa expected
1891 values when converting NaN and +-Inf to an integer.
1892
1893 * check/ldst.inc: Ensure double load/store tests use an
1894 8 byte aligned address by default.
1895
1896 * lib/lightning.c: Correct a bug found during tests in
1897 the new port, where qmul* and qdiv* were not properly
1898 setting one of the result registers as modified in the
1899 function, what would be a problem if the only "write"
1900 usage were the qmul* or qdiv*.
1901
1902 * check/varargs.tst, check/varargs.ok: Add one extra
1903 interleaved integer/double test to validate proper code
1904 generation in the extra case.
1905
1906 * check/lightning.c, configure.ac, include/lightning.h,
1907 include/lightning/Makefile.am,
1908 include/lightning/jit_private.h, lib/Makefile.am,
1909 lib/jit_disasm.c: Update for the hppa port.
1910
19112013-04-27 Paulo Andrade <pcpa@gnu.org>
1912
1913 * check/varargs.tst: Correct misplaced .align directive
1914 that was causing the double buffer to not be aligned at
1915 8 bytes.
1916 * lib/jit_ia64-cpu.c:
1917 Properly implement abi for excess arguments passed on
1918 stack.
1919 Simplify load/store with immediate displacement argument
1920 with zero value.
1921 Simplify some calls to "subi" changing to "addi" with
1922 a negative argument.
1923 Remove some #if 0'ed code, that could be useful in
1924 special conditions, but the most useful one would be
1925 to "optimize" "static" jit functions, but for the sake
1926 of simplicity, jit functions are implemented in a way
1927 that can be passed back to C code as C function pointers.
1928 Add an attribute to prototypes of several unused functions.
1929 These functions are defined for the sake of implementing all
1930 Itanium documented instructions, but a significant amount of
1931 them is not used by lightning.
1932 * lib/jit_ia64-fpu.c: Simplify load/store with zero immediate
1933 displacement and add unused attribute for functions not used
1934 by lightning, but required to provide macros implementing all
1935 Itanium documented instructions.
1936 * lib/jit_ia64.c: Update for the properly implemented abi
1937 for stack arguments.
1938 * lib/lightning.c: Mark an unused function as such.
1939
19402013-04-27 Paulo Andrade <pcpa@gnu.org>
1941
1942 lib/jit_ia64-cpu.c:
1943 Correct immediate range check of integer comparisons when
1944 inverting arguments.
1945 Correct gei_u that was not decrementing immediate when
1946 inverting arguments.
1947 Correct b?add* and b?sub* that were not properly updating
1948 the result register.
1949
19502013-04-27 Paulo Andrade <pcpa@gnu.org>
1951
1952 * lib/jit_ia64-cpu.c: Correct wrong mapping of 2 instructions
1953 in "M-, stop, M-, stop" translation, that was ignoring the
1954 last stop (implemented as a nop I- stop).
1955
1956 * lib/jit_ia64-fpu.c: Properly implement fnorm.s and fnorm.d,
1957 as well as the proper integer to float or double conversion.
1958
19592013-04-27 Paulo Andrade <pcpa@gnu.org>
1960
1961 * lib/jit_ia64-cpu.c: Correct bogus implementation of ldr_T
1962 for signed integers, that was using ld1.s, ld2.s and ld4.s.
1963 The ".s" stands for speculative load, not sign extend.
1964
1965 * lib/jit_ia64-fpu.c: Correct bogus implementation of ldxr_T
1966 for float and double. The third (actually, second) argument
1967 is indeed added to the base register, but the base register
1968 is modified. The actual M7 implementation was already correct,
1969 just the ldxr_f and ldxr_d implementation that was kept in
1970 a prototype state, misinterpreting what M7 does.
1971
19722013-04-27 Paulo Andrade <pcpa@gnu.org>
1973
1974 * lib/jit_ia64-cpu.c: Correct X2 pattern matching by preventing
1975 it to attempt to require a stop between the L and the X
1976 instruction; that is, check the registers and predicates
1977 before emitting the L instruction, not after.
1978
1979 * lib/jit_ia64-fpu.c: Slightly simplify and correct
1980 divr_f and divrd_d implementation.
1981
1982 * check/lightning.c: Add __ia64__ preprocessor define
519a9ea1 1983 on Itanium.
4a71579b
PC
1984
1985 * check/alu.inc, check/clobber.tst, check/float.tst: Define
1986 several macros conditionally to __ia64__. This is required
1987 because __ia64__ jit generation can use way too many memory,
1988 due to not implementing instruction reordering to avoid
1989 as much as possible "stops", what causes way too many nops
1990 to be generated, as well as the fact that division and
1991 remainder requires function calls, and float division
1992 requires significant code to implement.
1993
19942013-04-27 Paulo Andrade <pcpa@gnu.org>
1995
1996 * include/lightning.h: Add new backend specific movr_w_d,
1997 movr_d_w and movi_d_w codes as helpers to ia64 varargs
1998 functions arguments.
1999
2000 * lib/jit_ia64-cpu.c:
2001 Correct wrong encoding of A5 small integers.
2002 Correct define of "mux" instruction modifiers.
2003 Correct ordering of arguments and predicates of cmp_xy
2004 implementation with immediate arguments; like most other
2005 codes with an immediate, the immediate is the second, not
2006 the third argument.
2007
2008 * lib/jit_ia64-fpu.c: Actual implementation of the code
2009 to move to/from gpr to/from fpr, to implement varargs abi.
2010
2011 * lib/jit_ia64.c: Make fpr argument registers not allocatable
2012 as temporaries, no need for the extra checks when there are
2013 plenty registers.
2014
2015 * lib/jit_print.c, lib/lightning.c: Minor updates for the
2016 new movr_w_d, movr_d_w and movi_d_w codes.
2017
20182013-04-26 Paulo Andrade <pcpa@gnu.org>
2019
2020 * lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c: Correct code to
2021 also insert a stop to break an instruction group if a
2022 register is written more than once in the same group.
2023 This may happen if a register is argument and result of
2024 some lightning call (not a real instruction). The most
2025 common case should be code in the pattern:
2026 movl rn=largenum
2027 ...
2028 mov rn=smallnum
2029 where "rn" would end up holding "largenum".
2030 But the problem possibly could happen in other circumstances.
2031
20322013-04-26 Paulo Andrade <pcpa@gnu.org>
2033
2034 * include/lightning/jit_ia64.h, lib/jit_ia64-cpu.c,
2035 lib/jit_ia64-fpu.c, lib/jit_ia64.c:
2036 Relocate JIT_Rn registers to the local registers, as, like
2037 float registers, div/rem and sqrt are implemented as function
2038 calls, and may overwrite non saved scratch registers.
2039 Change patch_at to receive a jit_code_t instead of a
2040 jit_node_t, so that it is easier to "inline" patches when
2041 some instruction requires complex code to implement, e.g.
2042 uneq and ltgt.
2043 Correct arguments to FMA and FMA like instructions that,
2044 due to a cut&paste error were passing the wrong argument
2045 to the related F- implementation function.
2046 Rewrite ltgt to return the proper result if one (or both)
2047 of the arguments is unordered.
2048
20492013-04-26 Paulo Andrade <pcpa@gnu.org>
2050
2051 * include/lightning/jit_ia64.h, include/lightning/jit_private.h,
2052 lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c, lib/jit_ia64.c,
2053 lib/lightning.c: Rework code to detect need of a "stop" to
2054 also handle predicates, as if a predicate is written, it
2055 cannot be read in the same instruction group.
2056 Use a single jit_regset_t variable for all registers when
2057 checking need for a stop (increment value by 128 for
2058 float registers).
2059 Correct wrong "subi" implementation, as the code executed
2060 is r0=im-r1, not r0=r1-im.
2061 Use standard lightning 6 fpr registers, and rework to
2062 use callee save float registers, that may be spill/reloaded
2063 in prolog/epilog. This is required because some jit
2064 instructions implementations need to call functions; currently
2065 integer div/mod and float sqrt, what may change the value of
2066 scratch float registers.
2067 Rework point of "sync" of branches that need to return a
2068 patch'able address, because the need for a "stop" before a
2069 predicate read causes all branches to be the instruction
2070 in slot 0, as there is no template to "stop" and branch
2071 in the same instruction "bundle".
2072
20732013-04-25 Paulo Andrade <pcpa@gnu.org>
2074
2075 * include/lightning/jit_ia64.h, lib/jit_ia64-cpu.c,
2076 lib/jit_ia64-fpu.c, lib/jit_ia64.c: New files implementing
2077 the basic infrastructure of an Itanium port. The code
2078 compiles and can generate jit for basic hello world like
2079 functions.
2080
2081 * check/lightning.c, configure.ac, include/lightning.h,
2082 include/lightning/Makefile.am, include/lightning/jit_private.h,
2083 lib/Makefile.am, lib/lightning.c: Update for the Itanium
2084 port.
2085
2086 * lib/jit_mips-cpu.c, lib/jit_mips.c: Correct typo and
2087 make the jit_carry register local to the jit_state_t.
2088 This matches code reviewed in the Itanium port, that
2089 should use the same base logic to handle carry/borrow.
2090
20912013-04-10 Paulo Andrade <pcpa@gnu.org>
2092
2093 * include/lightning/jit_private.h, lib/jit_arm.c,
2094 lib/jit_mips-cpu.c, lib/jit_mips.c, lib/jit_ppc-cpu.c,
2095 lib/jit_ppc.c, lib/jit_print.c, lib/jit_sparc-cpu.c,
2096 lib/jit_sparc.c, lib/jit_x86-cpu.c, lib/jit_x86.c,
2097 lib/lightning.c: Change all jit_regset macros to take
2098 a pointer argument, to avoid structure copies when
2099 adding a port to an architecture with more than 64
2100 registers.
2101
21022013-04-08 Paulo Andrade <pcpa@gnu.org>
2103
2104 * lib/jit_arm.c, lib/jit_ppc.c: Do not rely on __clear_cache
2105 aligning to the next page boundary the end argument. It may
2106 actually truncate it.
2107
21082013-03-29 Paulo Andrade <pcpa@gnu.org>
2109
2110 * include/lightning/jit_private.h, lib/jit_arm.c, lib/jit_memory.c,
2111 lib/jit_mips.c, lib/jit_ppc.c, lib/jit_sparc.c, lib/jit_x86.c,
2112 lib/lightning.c: Do not start over jit generation if can grow
2113 the code buffer with mremap without moving the base pointer.
2114
21152013-03-29 Paulo Andrade <pcpa@gnu.org>
2116
2117 * lib/jit_memory.c: Implement a simple memory allocation wrapper
2118 to allow overriding calls to malloc/calloc/realloc/free, as well
2119 as ensuring all memory containing pointers is zero or points to
2120 allocated memory.
2121
2122 * include/lightning.h, include/lightning/jit_private.h: Definitions
2123 for the memory allocation wrapper.
2124
2125 * lib/Makefile.am: Update for new jit_memory.c file.
2126
2127 * lib/jit_arm.c, lib/jit_disasm.c, lib/jit_mips.c, lib/jit_note.c,
2128 lib/jit_ppc.c, lib/jit_sparc.c, lib/jit_x86.c, lib/lightning.c:
2129 Use the new memory allocation wrapper code.
2130
21312013-03-22 Paulo Andrade <pcpa@gnu.org>
2132
2133 * configure.ac, include/lightning/jit_private.h, lib/lightning.c:
2134 Remove dependency on gmp. Only a simple bitmap was required, and
2135 that was not enough reason to force linking to gmp and possible
2136 complications caused by it.
2137
21382013-03-10 Paulo Andrade <pcpa@gnu.org>
2139
2140 * include/lightning.h: Add check for __powerpc__ defined
2141 in Linux, while Darwin defines __ppc__.
2142
2143 * include/lightning/jit_ppc.h: Adjust register definitions
2144 for Darwin 32 bit and Linux 64 bit ppc usage and/or ABI.
2145
2146 * include/lightning/jit_private.h: Add proper check for
2147 Linux __powerpc__ and an data definition for an workaround
2148 to properly handle code that starts with a jump to a "main"
2149 label.
2150
2151 * lib/jit_disasm.c: Add extra disassembler initialization
2152 for __powerpc64__.
2153
2154 * lib/jit_ppc-cpu.c: Add extra macros and functions, and
2155 correct/adapt previous ones to handle powerpc64.
2156
2157 * lib/jit_ppc-fpu.c: Adapt for 64 bit wordsize. Basically
2158 add conversion from/to int32/int64 and proper handling of
2159 load/store offsets too large for 32 bit.
2160
2161 * lib/jit_ppc.c: Add calls to 64 bit codes and adaptation
2162 for the PowerPC 64 bit Linux ABI.
2163
2164 * lib/jit_arm.c, lib/jit_mips.c, lib/jit_sparc, lib/jit_x86.c,
2165 lib/lightning.c: Correct off by one error when restarting jit
2166 of a function due to finding too late that needs to spill/reload
2167 some register. Problem was found by accident on a very special
2168 condition during PowerPC 64 code adaptation.
2169
21702013-03-08 Paulo Andrade <pcpa@gnu.org>
2171
2172 * check/lightning.c: Add missing ppc preprocessor definition.
2173
21742013-03-06 Paulo Andrade <pcpa@gnu.org>
2175
2176 * check/float.tst: Comment out the int to negative infinity
2177 test in mips for the moment because not all Loongson agrees
2178 on the result.
2179
2180 * lib/jit_disasm.c: Add a test instead of an assertion
2181 when loading symbols for disassembly due to a failure with
2182 a simple binutils build in Debian mipsel64.
2183
21842013-03-06 Paulo Andrade <pcpa@gnu.org>
2185
2186 * include/lightning/jit_private.h, lib/jit_arm-cpu.c,
2187 lib/jit_arm.c, lib/jit_disasm.c, lib/jit_mips-cpu.c,
2188 lib/jit_mips.c, lib/jit_note.c, lib/jit_ppc-cpu.c,
2189 lib/jit_ppc.c, lib/jit_print.c, lib/jit_sparc-cpu.c,
2190 lib/jit_sparc.c, lib/jit_x86-cpu.c, lib/jit_x86.c,
2191 lib/lightning.c: Add an extra structure for data storage
2192 during jit generation, and release it after generating
2193 jit, to reduce a bit memory usage, and also to make it
2194 easier to understand what data is available during
2195 jit runtime.
2196
21972013-03-06 Paulo Andrade <pcpa@gnu.org>
2198
2199 * lib/lightning.c: Make data and code buffer readonly.
2200
22012013-02-20 Paulo Andrade <pcpa@gnu.org>
2202
2203 * doc/body.texi: Fool proof validate the examples of what
2204 an assembly-language programmer would write and correct the
2205 wrong sparc example.
2206
22072013-02-19 Paulo Andrade <pcpa@gnu.org>
2208
2209 * doc/body.texi: Add back the SPARC code generation example.
2210
22112013-02-19 Paulo Andrade <pcpa@gnu.org>
2212
2213 * check/lightning.c: Remove state flag to work with partial
2214 sparc port, by just disassembling if there was incomplete
2215 code generation.
2216
2217 * jit_sparc-cpu.c: Correct wrong range check for immediate
2218 integer constants (off by one bit shift).
2219 Correct macro implementing equivalent "rd %y, rd" assembly.
2220 Implement qmul* and qdiv*.
2221
2222 * jit_sparc.c: Update for qmul* and qdiv* and remove logic
2223 to handle incomplete code generation during sparc port.
2224
22252013-02-18 Paulo Andrade <pcpa@gnu.org>
2226
2227 * check/float.tst: Add sparc to list of known NaN and +-Inf
2228 to integer conversion.
2229
2230 * check/lightning.c: Define __sparc__ to preprocessor in
2231 the sparc backend.
2232
2233 * include/lightning/jit_private.h: Correct wrong definition
2234 of emit_stxi_d, that has lived for a long time, but would
2235 cause problems whenever needing to spill/reload a float
2236 register.
2237
2238 * include/lightning/jit_sparc.h: Can only use %g2,%g3,%g4
2239 for scratch variables, as other "global" registers are
2240 reserved for the system, e.g. libc.
2241 Reorder float register naming to make it easier to
2242 access odd float registers, so that generating code for
2243 pusharg and getarg is easier for the IR.
2244
2245 * lib/jit_mips-cpu.c, lib/jit_ppc-cpu.c: Update to match
2246 new code in jit_sparc-cpu.c. It must call jit_get_reg
2247 with jit_class_nospill if using the register to move
2248 an unconditional branch address to it, as the reload
2249 will not happen (actually could happen in the delay
2250 slot...)
2251
2252 * lib/jit_sparc-cpu.c: Correct wrong macro definition for
2253 ldxr_s.
2254 Properly implement div* and implement rem. Div* needs
2255 to use the y register, and rem* needs to be synthesized.
2256 Correct b?sub* macro definitions.
2257
2258 * lib/jit_sparc-fpu.c: Correct reversed float to/from double
2259 conversion.
2260 Correct wrong jit_get_reg call asking for a gpr and then
2261 using the fpr with that number.
2262 Correct wrong branch displacement computation for
2263 conditional branches.
2264
2265 * lib/jit_sparc.c: Correct getarg_d and pushargi_d implementation.
2266 Add rem* entries to the switch converting IR to machine code.
2267
2268 * lib/lightning.c: Correct a problem detected when adding
2269 the jit_class_nospill flag to jit_get_reg, that was caused
2270 when having a branch to an "epilog" node, what would cause
2271 the code to think all registers in unknown state were live,
2272 while in truth, all registers in unknown state in the
2273 "just after return" point are actually dead.
2274
22752013-02-17 Paulo Andrade <pcpa@gnu.org>
2276
2277 * include/lightning/jit_sparc.h, lib/jit_sparc-cpu.c,
2278 lib/jit_sparc-fpu.c, lib/jit_sparc.c: New files implementing
2279 the basic framework of the sparc port.
2280
2281 * configure.ac, include/lightning.h, include/lightning/Makefile.am,
2282 include/lightning/jit_private.h, lib/jit_disasm.c: Update
2283 for the sparc port framework.
2284
2285 * lib/jit_mips.c: Correct reversed retr/reti logic.
2286
2287 * lib/jit_ppc.c: Correct misspelled __LITTLE_ENDIAN.
2288
2289 * lib/lightning.c: Always do byte hashing in hash_data, because
2290 the logic to "compress" strings causes large pointers to not
2291 be guaranteed aligned at 4 byte boundaries.
2292 Update for the sparc port framework.
2293
22942013-02-11 Paulo Andrade <pcpa@gnu.org>
2295
2296 * lib/jit_arm.c: Correct jit_pushargi_f in the arm hardfp abi.
2297 Most of the logic uses even numbered register numbers, so that
2298 a float and a double can be used in the same register, but
2299 the abi requires packing the float arguments, so jit_pushargi_f
2300 needs to allocate a temporary register to modify only the
2301 proper register argument (or be very smart to push two
2302 immediate arguments if applicable).
2303
23042013-02-11 Paulo Andrade <pcpa@gnu.org>
2305
2306 * include/lightning.h, lib/lightning.c: Implement the new
2307 jit_clear_state and jit_destroy_state calls. jit_clear_state
2308 releases all memory not required during jit_execution; that
2309 is, leaves only the mmap'ed data and code buffers allocated.
2310 jit_destroy_state releases the mmap'ed buffers as well as
2311 the jit_state_t object itself, that holds pointers to the
2312 code and data buffers, as well as annotation pointers (for
2313 disassembly or backtrace) in the data buffer.
2314
2315 * lib/jit_note.c: Correct invalid vector offset access.
2316
2317 * check/ccall.c, check/lightning.c, doc/ifib.c, doc/incr.c,
2318 doc/printf.c, doc/rfib.c, doc/rpn.c: Use the new jit_clear_state
2319 and jit_destroy_state calls, to demonstrate the new code to
2320 release all jit memory.
2321
2322 * doc/body.texi: Add basic documentation and usage description
2323 of jit_clear_state and jit_destroy_state.
2324
23252013-02-11 Paulo Andrade <pcpa@gnu.org>
2326
2327 * include/lightning/jit_private.h, lib/jit_note.c, lib/lightning.c:
2328 Store all annotation information in the mmap'ed area reserved for
2329 read only data. This adds code to not allocate memory for jit_note_t
2330 objects, and to relocate jit_line_t objects and its contents after
2331 calculating annotation information. The jit_line_t objects are
2332 relocated because it is not possible to always calculate before
2333 hand data layout because note information may be extended or
2334 redundant entries removed, as well as allowed to be added in
2335 non sequential order.
2336 A bug was also corrected in _jit_set_note, that was causing it
2337 to allocate new jit_line_t objects when not needed. It was still
2338 working correctly, but allocating way more memory than required.
2339
23402013-02-05 Paulo Andrade <pcpa@gnu.org>
2341
2342 *include/lightning.h, lib/lightning.c: Add the new jit_live code
2343 to explicitly mark a register as live. It is required to avoid
2344 assuming functions always return a value in the gpr and fpr return
2345 register, and to avoid the need of some very specialized codes
2346 that vary too much from backend to backend, to instruct the
2347 optimization code the return register is live.
2348
2349 * lib/jit_arm.c, lib/jit_mips.c, lib/jit_ppc.c, lib/jit_print.c,
2350 lib/jit_x86.c: Update for the new jit_live code.
2351
2352 * check/ret.ok, check/ret.tst: New files implementing a simple
2353 test case that would previously fail at least in ix86/x86_64.
2354
2355 * check/Makefile.am: Update for new "ret" test case.
2356
23572013-02-05 Paulo Andrade <pcpa@gnu.org>
2358
2359 * lib/jit_ppc-cpu.c, lib/jit_ppc.c: Validate and correct
2360 problems in the qmul and qdiv ppc implementation.
2361
23622013-02-04 Paulo Andrade <pcpa@gnu.org>
2363
2364 * include/lightning.h, include/lightning/jit_private.h,
2365 lib/jit_arm-cpu.c, lib/jit_arm.c, lib/jit_mips-cpu.c,
2366 lib/jit_mips.c, lib/jit_ppc-cpu.c, lib/jit_ppc.c,
2367 lib/jit_x86-cpu.c, lib/jit_x86.c, lib/lightning.c:
2368 Implement the new qmul and qdiv instructions that return signed
2369 and unsigned lo/hi multiplication result and div/rem division result.
2370 These should be useful for jit translation of code that needs to
2371 know if a multiplication overflows (no branch opcode added) or if
2372 a division is exact (easy check if remainder is zero).
2373
2374 * check/lightning.c, lib/jit_print.c, check/Makefile.am,
2375 check/all.tst: Update for the new qmul and qdiv instructions.
2376
2377 * check/qalu.inc, check/qalu_div.ok, check/qalu_div.tst,
2378 check/qalu_mul.ok, check/qalu_mul.tst: New files implementing
2379 simple test cases for qmul and qdiv.
2380
23812013-01-30 Paulo Andrade <pcpa@gnu.org>
2382
2383 * doc/body.texi: Correct "jmpi" description that incorrectly
2384 told it was possible to pass any address as jump target. The
2385 only way to do that is "movi+jmpr".
2386
23872013-01-30 Paulo Andrade <pcpa@gnu.org>
2388
2389 * lib/jit_x86-cpu.c: Correct undefined behavior code.
2390 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56143
2391
23922013-01-29 Paulo Andrade <pcpa@gnu.org>
2393
2394 * configure.ac: Use AC_CONFIG_HEADERS instead of AC_CONFIG_HEADER
2395 to have HAVE_CONFIG_H defined with latest aclocal.
2396
2397 * include/lightning/jit_private.h, lib/lightning.c: Add new
2398 abstraction to use an heuristic to calculate amount of space
2399 required for jit generation, and code to reallocate buffer if
2400 did miscalculate it.
2401
2402 * lib/jit_arm.c, lib/jit_mips.c, lib/jit_ppc.c, lib/jit_x86.c:
2403 Update to use new code to estimate and resize of required buffer
2404 for jit code.
2405
2406 * lib/jit_x86-cpu.c: Minor cosmetic change to avoid adding a
2407 non required rex prefix when calling a function pointer stored
2408 in a register.
2409
24102013-01-24 Paulo Andrade <pcpa@gnu.org>
2411
2412 * check/Makefile.am: "make debug" target should pass only
2413 the main test tool program as argument for running gdb
2414
2415 * configure.ac: Add the --enable-assertions options.
2416
2417 * doc/Makefile.am, doc/body.texi, doc/lightning.texi:
2418 Major rewrite of the documentation to match the current
2419 implementation.
2420
2421 * doc/version.texi: Automatic date update.
2422
2423 * doc/ifib.c, doc/incr.c, doc/printf.c, doc/rfib.c, doc/rpn.c:
2424 Implementation of the documentation examples, that are also
2425 compiled during a normal build.
2426
2427 * doc/p-lightning.texi, doc/porting.texi, doc/toc.texi,
2428 doc/u-lightning.texi, doc/using.texi: These files were
2429 renamed in the documentation rewrite, as the documentation
2430 was significantly trimmed due to full removal of the porting
2431 chapters. Better porting documentation should be added but
2432 for the moment it was just removed the documentation not
2433 matching the implementation.
2434
24352013-01-18 Paulo Andrade <pcpa@gnu.org>
2436
2437 * lib/jit_note.c: Correct bounds check and wrong code keeping
2438 a pointer that could be changed after a realloc call.
2439
24402013-01-18 Paulo Andrade <pcpa@gnu.org>
2441
2442 * check/3to2.tst, check/add.tst, check/allocai.tst, check/bp.tst,
2443 check/call.tst, check/ccall.c, check/clobber.tst, check/divi.tst,
2444 check/fib.tst, check/ldsti.tst, check/ldstr-c.tst, check/ldstr.tst,

2449 lib/jit_mips.c, lib/jit_note.c, lib/jit_ppc.c, lib/jit_print.c,
2450 lib/jit_x86.c, lib/lightning.c: Extend the "jit_note" abstraction
2451 with the new "jit_name" call, that receives a string argument, and
2452 should usually be called to mark boundaries of functions of code
2453 generating jit (that is, it is not expected that the language
2454 generating jit map its functions to jit functions).
2455
24562013-01-17 Paulo Andrade <pcpa@gnu.org>
2457
2458 * check/add.tst, check/allocai.tst, check/bp.tst, check/divi.tst,
2459 check/fib.tst, check/lightning.c, include/lightning/jit_arm.h,
2460 include/lightning/jit_mips.h, include/lightning/jit_ppc.h,
2461 include/lightning/jit_private.h, include/lightning/jit_x86.h:
2462 Make JIT_RET, JIT_FRET and JIT_SP private. These should not be
2463 used in any operations due to frequently having special
2464 constraints (usually JIT_FRET). JIT_FP must be made available
2465 because it must be used as the base register to access stack
2466 space allocated with jit_allocai.
2467
24682013-01-14 Paulo Andrade <pcpa@gnu.org>
2469
2470 * include/lightning.h, lib/lightning.c: Add an extra align
2471 argument to the jit_data call (that should be made private),
2472 so that it should not align strings at 8 bytes.
2473 Correct the jit_note call to include the null ending byte
2474 when adding label/note names to the "jit data section".
2475
24762013-01-11 Paulo Andrade <pcpa@gnu.org>
2477
2478 * lib/jit_note.c: New file implementing a simple string+integer
2479 annotation, that should be used to map filename and line number
2480 to offsets in the generated jit.
2481
2482 * include/lightning.h, lib/lightning.c: Update for the new
2483 note code.
2484 Add an extra mandatory argument to init_jit, that is used
2485 as argument to bfd_openr.
2486 Change from generic void* to char* the argument to jit_note
2487 and add an extra integer argument, to map to filename and
2488 line number.
2489
2490 * check/ccall.c, check/lightning.c, include/lightning/jit_private.h,
2491 lib/jit_arm.c, lib/jit_disasm.c, lib/jit_mips.c, lib/jit_ppc.c,
2492 lib/jit_print.c, lib/jit_x86.c: lib/Makefile.am: Update for the
2493 new annotation code.
2494
2495 * configure.ac, check/Makefile.am: Update to work with latest
2496 automake.
2497
24982013-01-09 Paulo Andrade <pcpa@gnu.org>
2499
2500 * include/lightning.h, lib/jit_arm.c, jit_mips-fpu.c,
2501 lib/jit_mips.c, lib/jit_print.c, lib/jit_x86.c, lib/lightning.c:
2502 Remove the jit_code_getarg_{f,d} and jit_code_pusharg{i,r}_{f,d}
2503 calls, replacing them with the new, internal only, jit_movr_w_f,
2504 jit_mov{r,i}_f_w, jit_movr_ww_d, and jit_mov{i,r}_d_ww, that
2505 better describe the operation being done, and allow removing
2506 the hackish code to detect special conditions for arm when
2507 moving from/to vfp from/to a grp register pair.
2508 Rename jit_code_retval_{f,d} to jit_code_x86_retval_{f,d} as
2509 it is specific to 32 bit x86, and used to move abi return
2510 value in x87 register to a sse register.
2511
25122013-01-05 Paulo Andrade <pcpa@gnu.org>
2513
2514 * check/cccall.c, check/ccall.ok: New test case to validate
2515 interleaved calls from/to C code and jit.
2516
2517 * check/Makefile.am: Update for the new ccall test case.
2518
2519 * include/lightning.h, lib/lightning.c: Add the new jit_address
2520 call that returns the real/final address of a "note" in the
2521 generated jit. It requires a jit_node_t as returned by the
2522 jit_note call, and is only valid after calling jit_emit.
2523 Add an intermediate solution to properly handle arm
2524 soft and softfp modes that move a double to an integer register
2525 pair. Currently it just adds extra tests for the condition,
2526 but the proper solution should be to have extra lightning
2527 codes for these conditions, codes which should be only used
2528 by the backends that need it, and merged with the existing
2529 jit_pusharg*_{f,d}.
2530
2531 * include/lightning/jit_private.h: Add new jit_state_t flag
2532 to know it finished jit_emit, so that calls to jit_address
2533 are valid.
2534
2535 * lib/jit_mips.c: Correct abi implementation so that the
2536 new ccall test case pass. Major problem was using
2537 _jit->function.self.arg{i,f} as boolean values, but that
2538 would cause lightning.c:patch_registers() to incorrectly
2539 assume only one register was used as argument when calling
2540 jit_regarg_p(); _jit->function.self.arg{i,f} must be the
2541 number of registers used as arguments (in all backends).
2542
2543 * lib/jit_x86.c: Add workaround, by marking %rax as used,
2544 to a special condition, when running out of registers and the
2545 allocator trying to spill and reload %rax, but %rax was used
2546 as a pointer to a function, what would cause the reload to
2547 destroy the return value. This condition can be better
2548 generalized, but the current solution is good enough.
2549
2550 * include/lightning/jit_ppc.h, lib/jit_ppc-cpu.c, lib/jit_ppc.c:
2551 Rewrite logic to handle arguments, as the original code was
2552 written based on a SysV pdf about the generic powerpc ABI,
2553 what did "invent" a new abi for the previous test cases, but
2554 failed in the new ccall test in Darwin PPC. Now it properly
2555 handles 13 float registers for arguments, as well as proper
2556 computation of stack offsets when running out of registers
2557 for arguments.
2558
25592013-01-02 Paulo Andrade <pcpa@gnu.org>
2560
2561 * check/float.tst: Correct test case to match ppc also
2562 converting positive infinity to 0x7fffffff.
2563
2564 * lib/jit_arm-swf.c: Correct typos with double underscores.
2565
2566 * lib/lightning.c: Correct remaining wrong reverse jump logic.
2567
25682012-12-29 Paulo Andrade <pcpa@gnu.org>
2569
2570 * lib/lightning.c: Correct both, wrong and confusing logic
2571 to compute the reverse of a jump. Now it properly matches
2572 C semantics for "eq" (==) and "ne" (!=) and correct computation
2573 of reverse of "uneq" as "gt".
2574
2575 * check/branch.tst: Update "ne" float branch check that
2576 previously happened to be wrongly tested with a NaN argument.
2577
25782012-12-29 Paulo Andrade <pcpa@gnu.org>
2579
2580 * check/float.ok, check/float.tst: New test cases implementing
2581 extensive validation of float comparison and branch code
2582 generation as well as integer conversion, involving NaN and
2583 [+-]Inf.
2584
2585 * lib/jit_arm-swf.c, lib/jit_x86-sse.c, lib/jit_x86-x87.c:
2586 Correct bugs found by new float test case.
2587
2588 * lib/jit_x86.c: Correct cut&paste error added in commit to
2589 convert jit_arg* return value to a jit_node_t*, that would
2590 cause it to not properly handle double arguments in ix86.
2591
2592 * check/Makefile.am: Update for the new test case.
2593
25942012-12-28 Paulo Andrade <pcpa@gnu.org>

2597 lib/jit_mips.c, lib/jit_ppc.c, lib/jit_print.c, lib/jit_x86.c,
2598 lib/lightning.c: Change return value of jit_arg{,_f,_d} to
2599 a jit_node_t* object, that should be used as argument to
2600 jit_getarg_{c,uc,s,us,i,ui,l,f,d}. This just requires changing
2601 from jit_int32_t to jit_pointer_t (or jit_node_t*) the "handle"
2602 for the getarg calls, with the benefit that it makes it easy
2603 to implement patching of the stack address of non register
2604 arguments, this way allowing to implement variable size stack
2605 frames if applicable; useful if there are too many registers and
2606 jit functions uses only a few callee save registers.
2607
26082012-12-27 Paulo Andrade <pcpa@gnu.org>
2609
2610 * lib/jit_arm.c, lib/jit_mips-cpu.c, lib/jit_mips.c: Correct
2611 regressions when patching jit_calli for a forward function.
2612
2613 * lib/jit_ppc-cpu.c: Correct wrong arguments to ANDI opcode
2614 in jit_getarg_u{c,s} implementation.
2615
26162012-12-23 Paulo Andrade <pcpa@gnu.org>
2617
2618 * check/call.ok, check/call.tst: New test cases to validate
2619 simple typed argument and return values in function calls.
2620
2621 * check/lightning.c: Properly handle jit_movi of labels for
2622 backward and forward code labels.
2623
2624 * check/Makefile.am: Update for new test case.
2625
26262012-12-23 Paulo Andrade <pcpa@gnu.org>
2627
2628 * check/carry.ok, check/carry.tst: New test case to validate
2629 carry condition handling.
2630
2631 * check/Makefile.am: Update for new test case.
2632
26332012-12-22 Paulo Andrade <pcpa@gnu.org>
2634
2635 * lib/jit_ppc-cpu.c, lib/jit_ppc.c: Implement logic for
2636 jit_htonr for big endian, so that ppc (big endian) pass the
2637 new clobber.tst test case.
2638
26392012-12-22 Paulo Andrade <pcpa@gnu.org>
2640
2641 * lib/jit_arm.c: Correct use of wrong argument offset
2642 variable in armv7l or float/double argument for varargs
2643 function in armv7hl.
2644 Correct jit_getarg* logic in software float mode to
2645 match expected behavior in other backends, that is, if
2646 a function is not called, it is safe to use a few lightning
2647 calls before a next jit_getarg* call, as done in the test
2648 case check/stack.tst. The proper solution should be to
2649 extend the parser in lib/lightning.c to check if there is
2650 some float operation that will call some (libgcc?) function,
2651 but software float arm should be a very uncommon backend for
2652 lightning, so, just load the already in place arguments
2653 saved to stack, assuming the register argument was clobbered
2654 (what should not be the case most times...).
2655
26562012-12-22 Paulo Andrade <pcpa@gnu.org>
2657
2658 * check/clobber.ok, check/clobber.tst: New test case doing
2659 extensive validation tests to ensure registers not used in
2660 a operation are not clobbered.
2661
2662 * check/Makefile.am: Update for new test case.
2663
26642012-12-21 Paulo Andrade <pcpa@gnu.org>
2665
2666 * lib/lightning.c: Partially rewrite/revert code to compute
2667 initial register live state at the start of a basic block.
2668 The original logic was corrupted when adding optimizations
2669 to do as few computations as possible in jit_update. The
2670 reglive field must be always a known set of live registers
2671 at the start of a basic block. The value that was incorrect
2672 was the regmask field, that must be the set of registers
2673 that are in unknown state, because they are not known live,
2674 neither set (or possibly not set) in the basic block, and
2675 *must* store the state at the start of the basic block.
2676
26772012-12-20 Paulo Andrade <pcpa@gnu.org>
2678
2679 * include/lightning/jit_ppc.h: Correct mismatch of JIT_F{1,5}
2680 with enum codes, that were correct, and returned by jit_f().
2681
2682 * lib/jit_ppc-cpu.c, lib/jit_ppc-fpu.c, lib/jit_ppc.c: Properly
2683 implement and better describe values when generating stack
2684 frames.
2685
26862012-12-18 Paulo Andrade <pcpa@gnu.org>
2687
2688 * check/stack.ok, check/stack.tst: New files to test data
2689 integrity on a deep chain of stack frames.
2690
2691 * lib/jit_arm.c, lib/jit_arm-cpu.c, lib/jit_mips.c,
2692 lib/jit_mips-cpu.c, lib/jit_ppc.c, lib/jit_ppc-cpu.c,
2693 lib/jit_x86.c, lib/jit_x86-cpu.c: Calculate _jit->function->stack
2694 in the emit stage, otherwise it will calculate it wrong if
2695 need to jit_allocai space to spill registers.
2696
2697 * lib/lightning.c: Correct wrong offset when updating the
2698 "current" jit function pointer in the code that may need to
2699 allocate stack space to spill registers.
2700
2701 * check/lightning.c: Correct off by one data space check.
2702
2703 * check/Makefile.am: Update for new test case.
2704
27052012-12-17 Paulo Andrade <pcpa@gnu.org>
2706
2707 * check/fop_abs.ok, check/fop_abs.tst, check/fop_sqrt.ok,
2708 check/fop_sqrt.tst: New files implementing simple test cases
2709 for the extra float operations.
2710
2711 * check/Makefile.am: Update for new test cases.
2712
2713 * check/alu.inc: Add an extra macro to check for unordered
2714 equality on tests where it is expected to use NaN as an
2715 argument.
2716
2717 * check/lightning.c: Minor change for proper/common argument
2718 syntax handling ommiting arguments to options.
2719
27202012-12-17 Paulo Andrade <pcpa@gnu.org>
2721
2722 * check/Makefile.am: Automatically generate pattern list
2723 of tests with alternate jit generation options. This should
2724 prevent typos and needing to change multiple places after
2725 a change.
2726
27272012-12-14 Paulo Andrade <pcpa@gnu.org>
2728
2729 * check/lightning.c: Remove the ".cpu name value" syntax,
2730 as it was not able to do proper changes before the jit
2731 internal data structure was initialized. Now it supports
2732 several getopt options to force using different jit
2733 generation options, effectively replacing the previous
2734 syntax.
2735
2736 * check/run-test: Add simple extra logic to handle differently
2737 named test scripts, used to test things like x87 coprocessor
2738 in ix86, and arm instruction set or software float in armv7l.
2739
2740 * configure.ac: Add some AC_RUN_IFELSE calls to figure at
2741 compile time if can test different code generation options,
2742 and update Makefile generation accordingly.
2743
2744 * check/Makefile.am, lib/jit_arm.c, lib/jit_x86.c: Update to
2745 properly work with the test tool updating the jit_cpu global
2746 information.
2747
2748 * check/check.arm.sh, check/check.swf.sh, check/check.x87.sh:
2749 New wrapper files passing -mthumb=0, mvfp=0 and -mx87=1 to
2750 the test tool, if applicable, so that it can validate alternate
2751 code generation options on test hosts that support them.
2752
27532012-12-14 Paulo Andrade <pcpa@gnu.org>
2754
2755 * lib/jit_x86-x87.c, lib/jit_x86.c: Correct test cases in ix86
2756 when using the x87 coprocessor instead of sse2+.
2757
27582012-12-14 Paulo Andrade <pcpa@gnu.org>
2759
2760 * include/lightning.h, include/lightning/jit_private.h,
2761 lib/jit_arm.c, lib/jit_mips.c, lib/jit_ppc.c, lib/jit_x86.c,
2762 lib/lightning.c: Make jit_ellipsis implementation not
2763 backend specific. It is not intended to handle va_list
2764 like objects at runtime, as jit_arg* and jit_getarg*
2765 return constant values resolved at parse time, so, effectively
2766 it is not possible to create printf like jit functions, as
2767 there is no va_start, va_arg, va_end, etc, abstraction. This
2768 limitation should be kept for the sake of making new ports
2769 easier.
2770
27712012-12-14 Paulo Andrade <pcpa@gnu.org>
2772
2773 * include/lightning.h, lib/lightning.c: Add two extra wrapper
2774 functions to avoid need for excess pointer to/from word casts.
2775
2776 * check/lightning.c: Only need for pointer to/from word cast
2777 now is jit_movi, update accordingly.
2778
27792012-12-13 Paulo Andrade <pcpa@gnu.org>
2780
2781 * check/varargs.ok, check/varargs.tst: New test cases implementing
2782 simple varargs calls with a large amount of arguments to exercise
2783 excess arguments on stack.
2784
2785 * include/lightning.h: Include config.h if HAVE_CONFIG_H is
2786 defined.
2787
2788 * lib/jit_arm.c: Allocate a fpr register, not a gpr one for
2789 temporary when pushing varargs arguments in the stack.
2790
2791 * lib/jit_arm-swf.c: Correct code changing the wrong offset
2792 in jit_absr_d and jit_negr_d in software float.
2793
2794 * lib/jit_mips.c: Correct calculation of offsets of arguments
2795 on stack.
2796
2797 * lib/jit_ppc.c: Correct bogus logic for "next" offset of arguments
2798 on stack and adjust for fixed offset of stack arguments.
2799
28002012-12-12 Paulo Andrade <pcpa@gnu.org>
2801
2802 * include/lightning.h, lib/jit_arm.c, lib/jit_mips.c,
2803 lib/jit_ppc.c, lib/jit_x86.c, lib/lightning.c: Change jit_prepare
2804 to no longer receive an argument. If receiving an argument, it
2805 should be an ABI specifier, not a boolean if varargs or not,
2806 and add the new jit_ellipsis call, to specify where the
2807 ellipsis is in the C prototype of the function being called.
2808 Note that currently it is not supported to define varargs
2809 functions and it will be ignored if calling jit_ellipsis not
2810 in a prepare/finish* block, but this should be addressed.
2811
2812 * check/allocai.tst, check/alu_add.tst, check/alu_and.tst,
2813 check/alu_com.tst, check/alu_div.tst, check/alu_lsh.tst,
2814 check/alu_mul.tst, check/alu_neg.tst, check/alu_or.tst,
2815 check/alu_rem.tst, check/alu_rsh.tst, check/alu_sub.tst,
2816 check/alu_xor.tst, check/alux_add.tst, check/alux_sub.tst,
2817 check/bp.tst, check/branch.tst, check/cvt.tst, check/divi.tst,
2818 check/fib.tst, check/ldsti.tst, check/ldstr-c.tst,
2819 check/ldstr.tst, check/ldstxi-c.tst, check/ldstxi.tst,
2820 check/ldstxr-c.tst, check/ldstxr.tst, check/rpn.tst,
2821 check/lightning.c: Update for the change to jit_prepare and
2822 addition of jit_ellipsis.
2823
28242012-12-11 Paulo Andrade <pcpa@gnu.org>
2825
2826 * lib/jit_ppc-cpu.c: Make movr a function that checks arguments
2827 so that other code can safely assume it is a noop if src and dst
2828 are the same register.
2829 Implement rem{r,i}{,_u} as a div{,u}/mul/sub.
2830 Correct ANDIS, ORIS and XORIS calls to cast the argument to
2831 unsigned before the shift to avoid an assertion if the argument
2832 had the topmost bit set.
2833 Implement lshi, rshi and rshi_u as functions to test for a
2834 zero argument, that would otherwise trigger an assertion when
2835 computing the shift value.
2836 Do a simple implementation of bm{s,c}{r,i} with a temporary,
2837 "andr" of arguments and jump based on comparison with zero.
2838 Correct typo in ldxi_c.
2839
2840 * lib/jit_ppc-fpu.c: Correct wrong arguments to FDIV* and STF*.
2841
2842 * lib/jit_ppc.c: Correct wrong check for 6 instead of 8 integer
2843 arguments in registers. If calling a varargs function and
2844 passing a float or double argument, also either store the
2845 value in the stack or in integer registers, as varargs functions
2846 do not fetch it from float registers.
2847 Add "case" for new functions and incorrectly missing ones.
2848 Call libgcc's __clear_cache, that should know what to do
2849 if the hardware needs flushing cache before execution.
2850
2851 * lib/lightning.c: Do a simple/trivial logic in jit_regset_scan1,
2852 that should make it easier for the compiler to optimize it, and
2853 that also corrects the previously wrong code for big endian, and
2854 that was causing problems in ppc due to not saving all callee save
2855 registers as it was not "finding" them in the regset due to the
2856 little endian assumption bug.
2857
28582012-12-11 Paulo Andrade <pcpa@gnu.org>
2859
2860 * configure.ac: Only default to using the builtin disassembler
2861 if on GNU/Linux. This should be temporary, due to requiring
2862 /proc/self/exe.
2863 Correctly check $target_cpu for powerpc.
2864
2865 * include/lightning/jit_ppc.h: Correctly implement jit_v_num.
2866
2867 * include/lightning/jit_private.h: Declare proper prototype
2868 for jit_init_debug and jit_finish_debug.
2869
2870 * lib/jit_ppc-cpu.c: Remove code to save/restore callee save
2871 float registers, as it is not required since those float
2872 registers are not usable currently.
2873 Change prolog and epilog generation to, at least comparing
2874 code, match what gcc generates in "gcc -O0", but it is still
2875 failing in Darwin PPC, apparently due to the __clear_cache
2876 call not being enough, as frequently it will also fail to
2877 execute, and the code buffer is all zeroes.
2878
2879 * lib/lightning.c: Do not fail in jit_regset_scan1 calls due
2880 to passing 64 as argument on computers with 64 registers.
2881
28822012-12-10 Paulo Andrade <pcpa@gnu.org>
2883
2884 * lib/jit_mips-cpu.c: Correct all current test cases.
2885 Call the "xori" not the "XORI" macro for jit_xori implementation,
2886 as the XORI macro handles only 16 bit unsigned values.
2887 Call the "movr" macro, not the "movi" macro in the special
2888 case of adding or subtracting zero.
2889 Use the proper temporary register in the jit_andr implementation.
2890
28912012-12-09 Paulo Andrade <pcpa@gnu.org>
2892
2893 * check/alu.inc, check/alu_add.ok, check/alu_add.tst,
2894 check/alu_and.ok, check/alu_and.tst, check/alu_com.ok,
2895 check/alu_com.tst, check/alu_div.ok, check/alu_div.tst,
2896 check/alu_lsh.ok, check/alu_lsh.tst, check/alu_mul.ok,
2897 check/alu_mul.tst, check/alu_neg.ok, check/alu_neg.tst,

2900 check/alu_sub.ok, check/alu_sub.tst, check/alu_xor.ok,
2901 check/alu_xor.tst, check/alux_add.ok, check/alux_add.tst,
2902 check/alux_sub.ok, check/alux_sub.tst, check/branch.ok,
2903 check/branch.tst: New test cases for arithmetic and branch
2904 tests.
2905
2906 * check/Makefile.am: Update for new test cases.
2907
2908 * include/lightning/jit_private.h: Make the jit_reg_free_p
2909 macro shared by all backends. Previously was added for the
2910 arm backend, but is useful in the x86_64 backend when checking
2911 state of "special purpose register".
2912 Also add the new jit_class_named register class, that must be
2913 or'ed with the register value if calling jit_get_reg expecting
2914 an specific value, because the specific register value may be
2915 zero, that previously was treated as no register requested.
2916
2917 * lib/jit_arm-cpu.c: Correct argument order for T2_MVN.
2918
2919 * lib/jit_arm-swf.c: Call the proper function for double
2920 divide. The "software float" implementation just calls
2921 libgcc functions.
2922
2923 * lib/jit_arm.c: Return float/double values in the float
2924 register if using the hard float ABI.
2925
2926 * lib/jit_x86-cpu.c: Change the can_sign_extend_int_p macro
2927 to not include -0x80000000L, because there is code that
2928 "abuses" it and thinks it can negate the immediate value
2929 after calling that macro.
2930 Correct implementation of jit_subi that had a wrong code
2931 patch logic doing subtraction with reversed arguments.
2932 Correct REX prefix calculation in the jit_muli implementation.
2933 Correct logic to get/unget %*ax and %*dx registers in divremr
2934 and divremi.
2935 Correct divremi that was using the symbolic, unique %*ax
2936 value in on place (not using the _REGNO name suffix).
2937 Correct cut&paste error causing it to use "xor" instead of
2938 "or" in one code path of the jit_ori implementation.
2939 Correct several flaws when clobbering registers and/or when
2940 one of the arguments was %*cx in the rotshr wrapper function
2941 implementing most shift operations.
2942
2943 * lib/lightning.c: No longer expect that the backend be smart
2944 enough to know what to do when asking for a named register
2945 if that register is already an argument or is live. It fails
2946 if it is an argument, or if register is live, fails if cannot
2947 spill.
2948 No longer incorrectly assume that eqr_{f,d} and ltgr_{f,d} are
2949 safe to inverse value tests in jump thread optimization.
2950
29512012-12-05 Paulo Andrade <pcpa@gnu.org>
2952
2953 * check/Makefile.am, check/cvt.ok, check/cvt.tst: Add new
2954 "cvt" test case to test conversion from/to int/float types.
2955
2956 * check/lightning.c: Only define truncr_{f,d}_l in 64 bit mode.
2957
2958 * include/lightning.h: Correct typo that caused it to define
2959 jit_truncr_{f,d}_l in 32 bit mode.
2960
2961 * lib/jit_arm-cpu.c: Avoid assertion failure in the signed/unsigned
2962 extend opcodes generation as it shares an interface for 3 argument
2963 opcode generation.
2964
2965 * lib/jit_x86-cpu.c: Correct wrong argument passed to
2966 jit_unget_reg in the andi implementation and wrong byte
2967 unsigned extend code generation.
2968
2969 * lib/jit_x86-sse.c: Correct conversion from "word" to float or
2970 double as is dependent on wordsize.
2971
29722012-12-05 Paulo Andrade <pcpa@gnu.org>
2973
2974 * check/ldstr-c.ok, check/ldstr-c.tst, check/ldstxi-c.ok,
2975 check/ldstxi-c.tst, check/ldstxr-c.ok, check/ldstxr-c.tst:
2976 New test case files testing load clobbering the base and/or
2977 index register;
2978
2979 * check/ldst.inc: New file with common definition for all the
2980 ldst* test cases.
2981
2982 check/Makefile.am, check/ldsti.tst, check/ldstr.tst,
2983 check/ldstxi.tst, check/ldstxr.tst: Update for new common
2984 definitions file and new register clobber ldst tests.
2985
29862012-12-05 Paulo Andrade <pcpa@gnu.org>
2987
2988 * lib/jit_mips-fpu.c: Correct wrong register order in stxr_{f,d}
2989 in the mips backend.
2990
29912012-12-05 Paulo Andrade <pcpa@gnu.org>
2992
2993 * lib/jit_arm-vfp.c: Correct regression found in armv7l with
2994 latest test cases.
2995
29962012-12-05 Paulo Andrade <pcpa@gnu.org>
2997
2998 * check/ldstxi.tst, check/ldstxr.tst: Correct wrong argument
2999 order for 32 bit mode tests.
3000
3001 * configure.ac: Correct check for ix86 target_cpu.
3002
30032012-12-05 Paulo Andrade <pcpa@gnu.org>
3004
3005 * check/ldstr.ok, check/ldstr.tst, check/ldsti.ok,
3006 check/ldsti.tst, check/ldstxr.ok, check/ldstxr.tst,
3007 check/ldstxi.ok, check/ldstxi.tst:
3008 New test case files exercising a very large amount of
3009 register combinations to verify load/store implementation.
3010
3011 * check/Makefile.am: Update for new test cases.
3012
3013 * lib/jit_x86-cpu.c: Correct wrong argument order when
3014 computing REX prefix for {ld,st}r_T codes;
3015
30162012-12-04 Paulo Andrade <pcpa@gnu.org>
3017
3018 * lib/jit_mips-fpu.c, lib/jit_mips.c: Implement missing mips
3019 jit_sqrtr_{f,d} codes.
3020
3021 * check/all.tst, include/lightning.h, lib/jit_print.c: Change
3022 declaration order and call order in all.tst of {add,sub}c and
3023 {add,sub}x. *c must be called before to set the carry and *x
3024 second to use the carry and keep it set. The wrong call order
3025 was causing all.tst to fail in mips, where a register is
3026 allocated to keep a global carry state.
3027
30282012-12-04 Paulo Andrade <pcpa@gnu.org>
3029
3030 * include/lightning/jit_mips.h, lib/jit_mips-cpu.c,
3031 lib/jit_mips-fpu.c, lib/jit_mips.c: Correct float/double
3032 argument handling and make the mips backend pass the initial
3033 test cases.
3034
3035 * include/lightning.h, ib/jit_print.c, lib/lightning.c:
3036 Add extra enum values for argument handling functions that
3037 could not be abstracted to the current codes, that is, when
3038 float values need to move from/to gpr from/to fpr. It would
3039 be more tempting to add such primitives, but they would have
3040 wordsize limitations, and it is not expected to add codes
3041 with one gpr argument for 64 bit and two for 32 bit.
3042
3043 * lib/jit_ppc.c: Check _jit->function before calling jit_epilog()
3044 to avoid a runtime exception.
3045
30462012-12-04 Paulo Andrade <pcpa@gnu.org>
3047
3048 * include/lightning/jit_mips.h, lib/jit_mips.c: Update to
3049 make the mips backend compile in a qemu image.
3050
3051 * lib/jit_ppc.c: Minor adaptations to help in having the
3052 ppc backend compilable.
3053
30542012-12-03 Paulo Andrade <pcpa@gnu.org>
3055
3056 * configure.ac, include/lightning/jit_private.h, lib/jit_arm-cpu.c,
3057 lib/jit_arm-swf.c, lib/jit_arm.c, check/Makefile.am: Correct
3058 implementation of the arm backend port to build and pass the
3059 current test cases. Tested on armv7 with softfp abi.
3060
3061 * lib/jit_disasm.c: Rename and change prototype of static
3062 disassemble function as in the arm backend it is required
3063 to access state information stored in the jit_state_t object.
3064
3065 * check/3to2.tst, check/add.tst: Correct test case code assuming
3066 JIT_RO and JIT_RET are the same, and even if they are the same,
3067 the logic was incorrect because it must always call jit_retval*
3068 to fetch a function call return before any other instruction.
3069 The arm backend hash a special condition if jit_retval is not
3070 called, because "r0" is not JIT_R0, but is JIT_RET and *also*
3071 the first argument for a called function, so JIT_RET must be
3072 only used as an argument to jit_retval.
3073
30742012-12-03 Paulo Andrade <pcpa@gnu.org>
3075
3076 * check/all.tst, check/lightning.c: Only declare or use 64 bit
3077 interfaces on 64 bit builds.
3078
3079 * check/fib.tst: Use simpler logic to not need preprocessor
3080 conditionals for 32 or 64 bit.
3081
3082 * include/lightning.h: Only declare 64 bit macros on a 64 bit
3083 build. Code using lightning must know about wordsize and the
3084 jit generation limitations, also, this way it generates a
3085 compile time failure, not a runtime assertion.
3086
3087 * include/lightning/jit_x86.h: Correct typo in macro name.
3088
3089 * lib/jit_arm.c, lib/jit_arm-cpu.c, lib/jit_mips.c,

3091 lib/jit_x86.c, lib/jit_x86-cpu.c: Correct wrong code to get
3092 current jit function pointer.
3093
3094 * lib/lightning.c: Move call to the simplify() optimization
3095 to after register liveness is known. Previous code did work
3096 by accident but now with proper test cases the problem was
3097 noticed.
3098
3099 * lib/jit_disasm.c: Always cast bfd_vma to long long when
3100 passing it as printf argument.
3101
31022012-12-03 Paulo Andrade <pcpa@gnu.org>
3103
3104 * configure.ac, check/Makefile.am, check/check.sh,
3105 doc/Makefile.am, include/lightning/Makefile.am,
3106 lib/Makefile.am: Correct make distcheck.
3107
31082012-12-02 Paulo Andrade <pcpa@gnu.org>
3109
3110 * lib/jit_ppc.c: Assign copyright ownership to FSF.
3111
3112 * lib/jit_x86-cpu.c: Correct integer multiplication that was
3113 generating code with reversed register arguments.
3114
3115 * check/rpn.ok, check/rpn.tst: New test case file.
3116
31172012-12-02 Paulo Andrade <pcpa@gnu.org>
3118
3119 * lib/jit_x86-cpu.c, lib/jit_x86-sse.c, lib/jit_x86-x87.c:
3120 Actually change copyright owner to FSF as avertised.
3121

3125 lib/jit_ppc-cpu.c, lib/jit_ppc-fpu.c, lib/jit_ppc.c: New
3126 files implementing initial code different jit backends.
3127
3128 * include/lightning/jit_private.h: Add extra field to the
3129 private jit_patch_t type, required by the arm port.
3130
3131 * lib/Makefile.am: Update for the new backend implementation
3132 files.
3133
31342012-12-02 Paulo Andrade <pcpa@gnu.org>
3135
3136 * check/Makefile.am: Add proper "make clean" rule and missing
3137 check.sh to EXTRA_DIST.
3138
31392012-12-02 Paulo Andrade <pcpa@gnu.org>
3140
3141 * .gitignore: Update pattern of ignored files.
3142
3143 * check/Makefile.am: Add rule to build liblightning.la dependency
3144 in case of running "make check" before building the library.
3145

3158 lightning/sparc/asm.h, lightning/sparc/core.h,
3159 lightning/sparc/fp.h, lightning/sparc/funcs.h:
3160 Removed. The core logic is used in the new code, and new mips
3161 and arm ports will be added. At first, sparc will not be
3162 supported as it has not yet been ported to the new engine.

3176 tests/testfp.ok, tests-run-test: Removed previous test suite, in
3177 favor of a newer one in the check subdirectory.
3178
3179 * check/3to2.ok, check/3to2.tst, check/add.ok, check/add.tst,
3180 check/allocai.ok, check/allocai.tst, check/bp.ok, check/bp.tst,
3181 check/divi.ok, check/divi.tst, check/fib.ok, check/fib.tst:
3182 New sample input for the new test program, loosely matching
3183 several of the previous test cases.
3184
3185 * check/Makefile.am: New test suite makefile.
3186
3187 * check/check.sh, check/run-test: New wrapper files for the
3188 new test suite.
3189
3190 * check/lightning.c: New file. The main driver of the new test
3191 suite, that compiles to a parser of a very simple assembly like
3192 language, generates jit and executes it.
3193
3194 * check/all.tst: New file. A generic debug and sample test file
3195 with a directive to prevent it from being executed, and useful to
3196 read disassembly of all possible instructions, using a fixed set
3197 of registers.
3198
3199 * include/Makefile.am, include/lightning.h,

3205 lib/jit_x86.c, lib/lightning.c: New files. These files are
3206 written from scratch, only by <pcpa@gnu.org>, and have now
3207 copyright assignment to the FSF. This is the core of the new
3208 lightning rework. Previously it was integrated in code with
3209 a garbage collector and several custom types like vectors and
3210 hash tables, so this first code merge with lightning converts
3211 that code into a library extracting only the jit bits, and at
3212 first only for x86_64 GNU/Linux.
3213
3214 * lightning.h, m4/lightning.m4: Removed. These are no longer
3215 required in the new lightning code.
3216
3217 .gitignore, Makefile.am, configure.ac: Update for the new
3218 lightning code.
3219
32202012-12-02 Paulo Andrade <pcpa@gnu.org>
3221 * .cvsignore: Removed for extra cleanup.
3222
3223 * build-aux: Rename directory to m4.
3224
3225 * m4: Renamed to "default" name and for consistency with merge
3226 with code rework to be imported in lightning.
3227
3228 * .gitignore, configure.ac, Makefile.am, doc/Makefile.am:
3229 Update for build-aux to m4 rename.
3230

3236 opcode/ppc.h, opcode/sparc-dis.c, opcode/sparc-opc.c, opcode/sparc.h,
3237 opcode/sysdep.h: Removed. Do not bundle GNU binutils files.
3238
3239 * aclocal.m4, configure, Makefile.in, config.h.in, doc/Makefile.in,
3240 lightning/Makefile.in, tests/Makefile.in: Removed. Do not maintain
3241 autogenerated files that also generate too much diff noise when
3242 regenerated in git.
3243
3244 * build-aux/help2man, build-aux/texinfo.tex, build-aux/texi2dvi:
3245 Removed. Buildenvironment must have an up to date version from
3246 upstream installed.
3247
3248 * build-aux/config.guess, build-aux/config.sub, build-aux/depcomp,
3249 build-aux/install-sh build-aux/mdate-sh build-aux/missing: Removed.
3250 Do not maintain a copy of automake files in git. Release tarballs
3251 must use an up to date version.
3252
3253 * lightningize.in, doc/lightningize.1: Removed. Do not encourage
3254 bundling lightning in other packages. It should use a system package
3255 or a proper thirdy part subdirectory.
3256
3257 * INSTALL: Removed. Autoreconf removes it and creates a symlink
3258 when regenerating files, so, avoid conflicts in git and let
3259 automake create the symlink.
3260
3261 * .gitignore: Add INSTALL and autogenerated files.
3262
3263 * configure.ac, Makefile.am: Update for removal of opcode subdir,
3264 auto generated files and lightningize.
3265
3266 * tests/Makefile.am, tests/3to2.c, tests/add.c, tests/bp.c,

3276 tests/fibit.c, tests/funcfp.c, tests/incr.c, tests/printf.c,
3277 tests/rpn.c, tests/rpnfp.c, tests/sete.c, tests/testfp.c:
3278 Remove LIGHTNING_CROSS, it is half supported and incomplete.
3279
3280 * tests/3to2.c, tests/funcfp.c, tests/rpnfp.c: Remove preprocessor
3281 check on JIT_FPR. If no hardware registers are available, the backend
3282 must provide an alternative for software float.
3283
3284 * lightning/ppc/core.h, lightning/sparc/core.h, tests/Makefile.am:
3285 Remove JIT_NEED_PUSH_POP. It is absolutely not trivial to implement
3286 properly on some backends due to stack alignment constraints, and
3287 whenever it is required, using jit_allocai and using a properly
3288 aligned stack vector, or a heap buffer, is better.
3289
3290 * tests/push-pop.c, tests/push-pop.ok: Removed due to
3291 JIT_NEED_PUSH_POP no longer available.
3292
32932011-02-28 Paolo Bonzini <bonzini@gnu.org>
3294
3295 * lightning/i386/core-64.h: Add jit_add{c,x}{i,r}_l, jit_mulr_{l,ul}_,

3400
34012008-07-02 Laurent Michel <ldm@engr.uconn.edu>
3402
3403 * lightning/ppc/funcs.h (jit_flush_code): modified the computation
3404 of start/end. The pointer arithmetic was done without casting. It
519a9ea1 3405 prevented compilation with recent gcc versions.
4a71579b
PC
3406 * lightning/ppc/core.h (jit_pushr_i): The offset for the store was
3407 incorrect. Should have been 4 bytes below SP (not above).
519a9ea1
PC
3408 * lightning/ppc/core.h (jit_popr_i): The offset for the load was
3409 incorrect. Should have been 0 (not +8).

3423 definition...
3424 * lightning/i386/core-32.h: ... here; define jit_save so that
3425 the core.h has no effect on the 32-bit backend.
3426 * lightning/i386/core-64.h: Place JIT_R1/JIT_R2 in R10/R11,
3427 place outgoing arguments in the right spot from the beginning,
3428 define jit_save, fix jit_reg8/jit_reg16.
3429
34302008-06-15 Paolo Bonzini <bonzini@gnu.org>
3431
3432 * lightning/i386/core-64.h: Rewrite argument passing to
3433 support up to 6 arguments and generate less code.
3434
34352008-06-14 Laurent Michel <ldm@thorgal.homelinux.org>
3436
3437 * lightning/i386/core-64.h (jit_movi_l): When the operand is 0,

3483
3484 * lightning/i386/core-32.h: Use separate __APPLE__ and SysV
3485 prolog/ret macros. Subtract 12 bytes in __APPLE__ case to
3486 keep stack aligned, and always use LEAVE in the epilog.
3487
