2
3 * check/Makefile.am: Add test for the live instruction.
4 * check/live.ok: New file.
5 * check/live.tst: New file.
6 * doc/body.texi: Add documentation for the live instruction and
7 for jit_get_reg/jit_get_unreg. Fix menu entries.
8 * include/lightning.h.in (jit_get_reg, jit_unget_reg): Expose the
9 macros in the public header file.
10 * include/lightning/jit_private.h (jit_get_reg, jit_unget_reg):
11 Remove the macros from the private header file.
12
132021-04-03 Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de>
14
15 * Makefile.am, check/Makefile.am, doc/Makefile.am,
16 lib/Makefile.am: Include $(top_builddir)/include in include paths
17 for the autoconf-generated header file lightning.h.
18
192021-04-03 Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de>
20
21 * doc/.gitignore: Add version.texi to list of ignored files.
22 * doc/version.texi: Remove file from version control.
23
242020-18-04 Paulo Andrade <pcpa@gnu.org>
25
26 * lib/jit_x86-cpu.c, lib/jit_x86.c: Implement %rip relative
27 calls and jumps on x86_64. Currently very conservative, assuming
28 a jit block can be larger than 2G, so, if a jump or call is in
29 the same jit generation, but target is unknown, use an indirect
30 branch (could have an option to assume a jit code block is
31 never larger than 2G). Also a deoptimization is that now does
32 not always generate ip relative jmpi; previously implicitly
33 assumed jmpi would never be larger than 2G. Overall still an
34 optimization.

362020-23-01 Paulo Andrade <pcpa@gnu.org>
37
38 * lib/lightning.c: Add a proper fix to the condition of considering
39 a register dead at entry of a block when it modifies the register
40 !after! a branch to a target where it is live.
41 The correction is just to split blocks on branches. It uses an
42 extra label per branch, but makes following the code simpler and
43 avoid costly searches.
44
452020-22-01 Paulo Andrade <pcpa@gnu.org>
46
47 * lib/lightning.c: Correct a special condition of a register
48 only assigned in a block, and incorrectly marked as dead before
49 a jump where the register is live.
50
512019-10-04 Paulo Andrade <pcpa@gnu.org>
52
53 * check/lightning.c, include/lightning/jit_private.h,
54 include/lightning/jit_x86.h, lib/jit_x86-cpu.c, lib/jit_x86-sz.c,
55 lib/jit_x86.c: Correct issues with MinGW64 that defines _WIN32
56 and needs long long for jit_word_t.
57
582019-09-16 Paulo Andrade <pcpa@gnu.org>
59
60 * lib/lightning.c: Do not add registers that are never modified
61 to the set of registers to scan for live range, what might
62 consume a lot of cpu time, doing nothing.
63
519a9ea1 642019-09-16 Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de>
4a71579b
PC
65
66 * include/lightning/jit_x86.h, lib/jit_x86.c: Correct x86_64
67 backend, made %r12 a callee-save register as dictated by the
68 System V AMD64 ABI.
69
702019-09-16 Paulo Andrade <pcpa@gnu.org>
71
72 * Makefile.am: Do not force CFLAGS for the get_jit_size target.
73 * check/lightning.c: Drop __ppc__ check.
74 * include/lightning.h.in: Drop __ppc__ check. Add new
75 jit_flag_vararg flag, for special case in powerpc 32 bit using
76 the SYSV abi, and need to pass an extra argument during code
77 generation.
78 * include/lightning/jit_ppc.c: Drop __ppc_ check. Remove the
79 ABI_ELFv2 macro, as it now directly checks for the _CALL_ELF
80 value when/if appropriate.
81 * include/lightning/jit_private.h: Drop __ppc_ check. Check for
82 _CALL_AIXDESC to define extra data to handle function
83 descriptors.
84 * lib/jit_ppc-cpu.c: Update to check for _CALL_SYSV; assume
85 !_CALL_SYSV == (_CALL_AIX || _CALL_LINUX). Significant code
86 rework for the SYSV abi.
87 * lib/jit_ppc-sz.c: Update for the SYSV abi.
88 * lib/jit_ppc.c: Update for the SYSV abi. Add matching va_list
89 type. Drop __ppc__ check.
90 * lib/jit_size.c: Drop __ppc_ check.
91 * lib/lightning.c: Drop __ppc__ check. Add proper check for
92 __powerpc__ and _CALL_AIXDESC to manage function descriptors.
93 * lib/size.c: Update to drop __pppc_ check and SYSV abi.
94
952019-08-30 Paulo Andrade <pcpa@gnu.org>
96
97 * lib/jit_mips-cpu.c: Use JALR to get the same effect as JR, as
98 in mips32r6 JR generates an illegal instruction. Thanks to
99 Bruno Haible for providing a patch and the information, reported at
100 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=925129
101 * THANKS: update.

104
105 * include/lightning/jit_private.h: Move definition of offsetof
106 from the public header file here.
107
108 * configure.ac, include/Makefile.am, include/lightning.h,
109 include/lightning.h.in: Generate lightning.h from lightning.in.h
110 and remove the dependence on config.h from the public header file.
111
1122019-06-04 Paulo Andrade <pcpa@gnu.org>
113
114 * include/lightning/jit_riscv.h, lib/jit_riscv-cpu.c,
115 lib/jit_riscv-fpu.c, lib/jit_riscv-sz.c, lib/jit_riscv.c:
116 Implement riscv port. Only 64 bit Linux supported. Built on
117 Fedora 28 image.
118
119 * check/all.tst, check/float.tst, configure.ac, include/lightning.h,
120 include/lightning/Makefile.am, include/lightning/jit_private.h,
121 lib/Makefile.am, lib/jit_disasm.c, lib/jit_size.c, lib/lightning.c:
122 Minor updates for the new riscv port.
123
1242019-06-04 Paulo Andrade <pcpa@gnu.org>
125
126 * lib/jit_alpha.c lib/jit_ia64.c lib/jit_mips.c lib/jit_sparc.c:
127 Correct assertion of _jitc->regarg after emiting an instruction.
128 jit_carry may be set, but not an argument to the current instruction.
129
1302019-06-01 Paulo Andrade <pcpa@gnu.org>
131
132 * lib/lightning.c: Correct assertion on jit_unget_reg when the
133 argument is jit_carry, and jit_carry was not used in the
134 instruction.
135
1362019-06-01 Paulo Andrade <pcpa@gnu.org>
137
138 * include/lightning/jit_private.h: Remove no longer need
139 setmask field of jit_block_t and blockmask from jit_compiler_t.
140
141 * lib/lightning.c: Rework of register live and unknown state
142 information during jit generation. It no longer recurses nor
143 do dangerous bit unset of registers in unknown state. The
144 only pitfall known, that must be taken care now is that jmpr
145 (or jmpi to not a jit node) is treated as a function call, as
146 otherwise it would need to consider all registers live, and
147 spill/reload during all jit generation.
148
1492018-12-28 Paulo Andrade <pcpa@gnu.org>
150
151 * lib/jit_disasm.c: Release bfd handle. Thanks for patch to
152 Marc Nieper-Wißkirchen.
153
1542018-08-30 Paulo Andrade <pcpa@gnu.org>
155
156 * lib/jit_disasm.c: Add hints to select hppa disassembler.
157
158 * lib/jit_hppa-cpu.c: Correct address of vastart when all
159 argument registers were used as non vararg arguments.
160
161 * lib/jit_hppa-fpu.c: Disable load/store of rv,ix,rb where
162 rv is the value, ix is an register or integer offset and rb
163 is a base register. These should be better tested, as they do
164 not work on all environments (fail on qemu-hppa).
165
1662018-04-20 Paulo Andrade <pcpa@gnu.org>
167
168 * include/lightning/jit_private.h: Add new register classes to
169 flag float registers and double only registers, required for sparc64
170 where only low 32 bit fpr registers can be used for single precision
171 operations.
172 Add new 128 bit jit_regset_t type for sparc64 register set.
173
174 * include/lightning/jit_sparc.h, lib/jit_sparc-cpu.c, lib/jit_sparc-fpu.c,
175 lib/jit_sparc-sz.c, lib/jit_sparc.c: Update for 64 bits sparc.
176
177 * lib/lightning.c: Update for new jit_regset_t required for sparc64.
178
1792018-02-26 Paulo Andrade <pcpa@gnu.org>
180
181 * check/lightning.c, include/lightning.h: Add the new jit_va_push
182 interface. That should be called when passing a va_list to a C
183 function. This is required because on Alpha a va_list is passed
184 by value, and lightning does not know about data types, so, cannot
185 understand it is pushing a va_list as argument.
186
187 * lib/jit_names.c, lib/lightning.c: Minor changes for the new
188 jit_code_va_push.
189
190 * check/cva_list.c: Update only test case using jit_va_push, to
191 pass a va_list to a C function.
192
193 doc/body.texi: Better documentation of the varargs interface.
194
195 * jit_alpha.c, jit_alpha-cpu.c: Update to properly push a
196 C va_list and correctly calculate varargs offset.
197
198 * lib/jit_aarch64-sz.c, lib/jit_aarch64.c, lib/jit_alpha-sz.c,
199 lib/jit_arm-sz.c, lib/jit_arm.c, lib/jit_hppa-sz.c, lib/jit_hppa.c,
200 lib/jit_ia64-sz.c, lib/jit_ia64.c, lib/jit_mips-sz.c, lib/jit_mips.c,
201 lib/jit_ppc-sz.c, lib/jit_ppc.c, lib/jit_s390-sz.c, lib/jit_s390.c,
202 lib/jit_sparc-sz.c, lib/jit_sparc.c, lib/jit_x86-sz.c, lib/jit_x86.c:
203 Update for the new jit_va_push interface.
204
2052018-02-22 Paulo Andrade <pcpa@gnu.org>
206
207 * lib/jit_alpha-cpu.c: Always set t12 to the address of the
208 current function, to properly work on all systems. Previously
209 the shortcut did only work on Tru64. For Linux and glibc the
210 change is required.
211
2122018-02-22 Paulo Andrade <pcpa@gnu.org>
213
214 * lib/jit_aarch64.c, lib/jit_alpha.c, lib/jit_arm.c,
215 lib/jit_mips.c, lib/jit_ppc.c, lib/jit_sparc.c, lib/jit_x86.c:
216 Correct wrong logic in usage of jit_live in jit_retr. The
217 problem is that if a temporary is required during epilog,
218 the return register might be allocated, so, jit_live must always
219 be used.
220
2212018-01-31 Paulo Andrade <pcpa@gnu.org>
222
223 * lib/lightning.c: Avoid deep recursions when computing live
224 register ranges.
225
2262018-01-31 Paulo Andrade <pcpa@gnu.org>
227
228 * lib/jit_mips-cpu.c: Correct frame size and varargs
229 initialization for the n32 abi.
230 * lib/jit_mips.c, lib/jit_mips-fpu.c: Correct 32 bit abis
231 in big-endian.
232
2332017-09-13 Paulo Andrade <pcpa@gnu.org>
234
235 * configure.ac: Add check for binutils 2.29 prototype to the
236 disassembler function.
237 * lib/jit_disasm.c: Adapt for binutils 2.29 change.
238
2392017-06-09 Paulo Andrade <pcpa@gnu.org>
240
241 * include/lightning/jit_private.h, lib/lightning.c: Add a
242 second pass from start when computing register live ranges.
243 This should be used temporarily, and is required for certain
244 loop constructs, with several consecutive blocks not referencing
245 a live register.
246
2472016-05-05 Paulo Andrade <pcpa@gnu.org>
248
249 * lib/lightning.c: Correct wrong movr simplification,
250 remove no longer needed code to set return registers live
251 and update live register set when reaching a label boundary,
252 but do not descend if the block has been already visited.
253 The later need some tuning for complex code generation, where
254 it will still have issues.
255
2562015-11-30 Paulo Andrade <pcpa@gnu.org>
257
258 * doc/body.texi: Change documentation to no longer say
259 it is a variant of the Fibonacci sequence, and document
260 a proper implementation.
261 Thanks to Jon Arintok for pointing out that the Fibonacci
262 sequence generation was incorrect. It was documented, but
263 still confusing.
264
265 * check/fib.tst, check/fib.ok, check/bp.tst, check/bp.ok,
266 doc/ifib.c, doc/rbif.c: Implement a proper Fibonacci
267 sequence implementation.
268
2692015-07-03 Paulo Andrade <pcpa@gnu.org>
270
271 * lib/jit_mips-cpu.c: Correct definition of htonr_ul.
272 Correct prolog/epilog/va* routines to work on o64 abi.
273
274 * lib/jit_mips-fpu.c: Correct load of double literal
275 argument when not using a data buffer.
276 Remove alignment correction in vaarg_d if using the
277 new mips abi.
278
279 * lib/jit_mips.c: Correct code to allow creating variadic
280 jit functions when using the new mips abi.
281
282 * lib/jit_rewind.c: Minor adjust for rewind when using
283 the new mips abi, if there are varargs arguments in
284 registers.
285
2862015-06-06 Paulo Andrade <pcpa@gnu.org>
287
288 * lib/jit_ia64-cpu.c: Search backward for the last output
289 register used, otherwise would stop too early if a float
290 argument used the slot.
291 Correct offset of first va_list argument, and use proper
292 va_list abi.
293
294 * lib/jit_ia64-fpu.c: Add new functions to move a gpr
295 to a fpr register, to counterpart the ones that move a
296 fpr to a gpr. These are required to properly implement
297 jit_getarg*_{f,d} on complex prototypes, or variadic
298 jit functions.
299
300 * lib/jit_ia64-sz.c: Update for support to jit variadic
301 functions.
302
303 * lib/jit_ia64.c: Implement proper abi for variadic
304 jit functions.
305
3062015-06-04 Paulo Andrade <pcpa@gnu.org>
307
308 * lib/jit_rewind.c: New file implementing generic functions
309 to "rewind", or rewrite IR code sequences.
310
311 * include/lightning.h: Add several new codes, that previously
312 were a function call, that would synthesize the operation.
313 Now, there is a code for the operation, and a new flag to
314 know an operation is synthesized.
315
316 * include/lightning/jit_private.h: Add several new macros to
317 help construct synthesized IR code sequences.
318
319 * lib/Makefile.am: Update for lib/jit_rewind.c.
320
321 * lib/jit_disasm.c: Update for a small rework on jit_node_t,
322 so that --enable-devel-disassembler does not need a change
323 in the layout of jit_node_t.
324
325 * lib/jit_names.c: Update for the new codes.
326
327 * lib/jit_print.c: Update to print more readable output, and
328 flag synthesized IR code sequences.
329
330 * lib/jit_aarch64-sz.c, lib/jit_aarch64.c,
331 lib/jit_arm-sz.c, lib/jit_arm.c, lib/jit_x86-sz.c,
332 lib/jit_x86.c: Update for new synthesized IR code sequences.
333
334 * lib/jit_ppc-cpu.c, lib/jit_ppc-fpu., lib/jit_ppc-sz.c,
335 lib/jit_ppc.c, lib/jit_mips-cpu.c, lib/jit_mips-fpu.c,
336 lib/jit_mips-sz.c, lib/jit_mips.c, lib/jit_s390-fpu.c,
337 lib/jit_s390-sz.c, lib/jit_s390.c: Update for new synthesized
338 IR code sequences and correct bugs in the initial varargs
339 implementation support.
340
341 * lib/jit_alpha-sz.c, lib/jit_alpha.c, lib/jit_hppa-sz.c,
342 lib/jit_hppa.c, lib/jit_ia64-sz.c, lib/jit_ia64.c,
343 lib/jit_sparc-sz.c, lib/jit_sparc.c: Add generic, untested
344 support for the new synthesized IR code sequences. Known
345 most likely broken right now, and should be corrected once
346 access to these hosts is available.
347
348 * lib/lightning.c: Update for new IR codes, and add support
349 for not yet existing instructions that change third argument.
350
351 * size.c: Change to use different tables for LE and BE PowerPC.
352 Correct a wrong endif for x32.
353
3542015-05-25 Paulo Andrade <pcpa@gnu.org>
355
356 * check/cva_list.c: New file implementing a test to ensure
357 the value returned by jit_va_start is a valid C va_list.
358
359 * check/va_list.ok: New simple helper file, as now the
360 va_list.tst test is enabled.
361
362 * check/va_list.tst: Rewritten for an extensive variadic
363 jit functions test.
364
365 * check/Makefile.am: Update for the new tests.
366
367 * lib/jit_arm-cpu.c, lib/jit_arm-swf.c, lib/jit_arm-vfp.c,
368 lib/jit_arm.c: Correct broken software float in a previous
369 commit. Note that the hard float abi implementation is known
370 broken at this time, for special cases involving variadic
371 functions, and should be corrected next.
372
373 lib/jit_x86-cpu.c, lib/jit_x86-sz.c, lib/jit_x86.c: Correct
374 the jit_va_list_t semantics to match C va_list.
375
3762015-05-24 Paulo Andrade <pcpa@gnu.org>
377
378 * lib/Makefile.am: Bump library major. This is a preparation
379 for a rework that was due for quite some time, but that is
380 now required to properly implement variadic jit functions.
381 The rework is mainly required to know at prolog parsing, if
382 a function is variadic or not. This will benefit a few
383 backends, and is mandatory for the hard float arm abi.
384 The rework was already planned for quite some time, to
385 be able to use a variable stack framesize, and for leaf
386 functions optimization where applicable.
387 The change will be source compatible, but will change
388 some internals, and jit_code_t values, as some new will
389 be added.
390 The only behavior change is that, jit_arg_register_p may
391 change return value on hard float arm abi, if called before
392 or after jit_ellipsis. Common sense anyway, would say to
393 make that call after jit_ellipsis, but documentation
394 should be updated for it.
395
3962015-05-24 Paulo Andrade <pcpa@gnu.org>
397
398 * lib/jit_aarch64-fpu.c, lib/jit_aarch64.c: Correct base
399 aarch64 varargs code.
400
4012015-05-24 Paulo Andrade <pcpa@gnu.org>
402
403 * check/lightning.c: Clearly run check if clang is the system
404 compiler.
405
4062015-05-20 Paulo Andrade <pcpa@gnu.org>
407
408 * lib/jit_sparc-cpu.c, lib/jit_sparc-fpu.c, lib/jit_sparc.c:
409 Add base support to jit vararg functions to the sparc backend.
410
4112015-05-20 Paulo Andrade <pcpa@gnu.org>
412
413 * lib/jit_alpha-cpu.c, lib/jit_alpha-fpu.c, lib/jit_alpha.c:
414 Add base support to jit vararg functions to the alpha backend.
415
4162015-05-19 Paulo Andrade <pcpa@gnu.org>
417
418 * lib/jit_hppa-cpu.c, lib/jit_hppa-fpu.c, lib/jit_hppa.c:
419 Add base support to jit vararg functions to the hppa backend.
420
4212015-05-10 Paulo Andrade <pcpa@gnu.org>
422
423 * lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c, lib/jit_ia64.c:
424 Add base support to jit vararg functions to the ia64 backend.
425
4262015-05-10 Paulo Andrade <pcpa@gnu.org>
427
428 * lib/jit_ia64-fpu.c, lib/jit_ia64.c: Correct movi_d_w
429 and movi_f_w implementation to work when not using a
430 data buffer. This causes the check varargs.tst to
431 work when passing "-d" to the lightning test tool.
432
4332015-05-10 Paulo Andrade <pcpa@gnu.org>
434
435 * lib/jit_ia64.c: Implement inline assembly cache flush,
436 required on multiprocessor systems.
437
4382015-05-06 Paulo Andrade <pcpa@gnu.org>
439
440 * lib/jit_mips-cpu.c, lib/jit_mips-fpu.c, lib/jit_mips.c:
441 Add base support to jit vararg functions to the mips backend.
442 Currently only supported on the o32 abi, until access to a
443 n32 system is arranged.
444
4452015-05-05 Paulo Andrade <pcpa@gnu.org>
446
447 * lib/jit_ppc-cpu.c, lib/jit_ppc-fpu.c, lib/jit_ppc.c:
448 Add base support to jit vararg functions to the PowerPC backend.
449
4502015-05-02 Paulo Andrade <pcpa@gnu.org>
451
452 * lib/jit_s390-cpu.c, lib/jit_s390-fpu.c, lib/jit_s390.c:
453 Add base support to jit vararg functions to the s390 backend.
454
4552015-05-01 Paulo Andrade <pcpa@gnu.org>
456
457 * lib/jit_arm-cpu.c, lib/jit_arm-swf.c, lib/jit_arm-vfp.c,
458 lib/jit_arm.c: Add base support to jit vararg
459 functions to the arm backend.
460
4612015-04-30 Paulo Andrade <pcpa@gnu.org>
462
463 * lib/jit_aarch64-cpu.c, lib/jit_aarch64-fpu.c,
464 lib/jit_aarch64.c: Add base support to jit vararg
465 functions to the aarch64 backend.
466
4672015-04-27 Paulo Andrade <pcpa@gnu.org>
468
469 * include/lightning.h, include/lightning/jit_private.h,
470 lib/jit_names.c, lib/lightning.c: Add initial support
471 for the new jit_va_start, jit_va_arg, jit_va_arg_d, and
472 jit_va_end interfaces. The jit_va_start call is supposed
473 to return a va_list compatible pointer, but not yet
474 decided if it will be "declared" stdarg compatible,
475 as for now only x86 support has been added (and should
476 be compatible), but issues may arise on other backends.
477
478 * check/lightning.c: Add wrappers to call the new jit_va_*
479 interfaces.
480
481 * lib/jit_x86-cpu.c, lib/jit_x86.c: Implement the new
482 jit_va_* for x86.
483
484 * lib/jit_x86-sz.c: Add fields, but not yet fully updated,
485 as this is an intermediate commit.
486
487 * lib/jit_aarch64-sz.c, lib/jit_aarch64.c,
488 lib/jit_alpha-sz.c, lib/jit_alpha.c,
489 lib/jit_arm-sz.c, lib/jit_arm.c,
490 lib/jit_hppa-sz.c, lib/jit_hppa.c,
491 lib/jit_ia64-sz.c, lib/jit_ia64.c,
492 lib/jit_mips-sz.c, lib/jit_mips.c,
493 lib/jit_ppc-sz.c, lib/jit_ppc.c,
494 lib/jit_s390-sz.c, lib/jit_s390.c,
495 lib/jit_sparc-sz.c, lib/jit_sparc.c: Prepare for the
496 new jit_va_* interfaces. Not yet implemented, and will
497 cause an assertion if used.
498
499 * check/va_list.tst: Simple early test case, that works
500 on x86_64, x32, ix86, cygwin, and cygwin64.
501
5022015-02-17 Paulo Andrade <pcpa@gnu.org>
503
504 * include/lightning.h, include/lightning/jit_private.h,
505 lib/jit_aarch64-cpu.c, lib/jit_aarch64.c,
506 lib/jit_alpha-cpu.c, lib/jit_alpha.c,
507 lib/jit_arm-cpu.c, lib/jit_arm.c,
508 lib/jit_hppa-cpu.c, lib/jit_hppa.c,
509 lib/jit_ia64-cpu.c, lib/jit_ia64.c,
510 lib/jit_mips-cpu.c, lib/jit_mips.c,
511 lib/jit_ppc-cpu.c, lib/jit_ppc.c,
512 lib/jit_s390-cpu.c, lib/jit_s390.c,
513 lib/jit_sparc-cpu.c, lib/jit_sparc.c,
514 lib/jit_x86-cpu.c, lib/jit_x86.c: Implement the new
515 jit_allocar(offs, size) interface, that receives
516 two integer registers arguments, allocates space
517 dynamically in the stack, returns the offset in
518 the first argument, and uses the second argument
519 for the size in bytes of the memory to be allocated.
520
521 * check/allocar.ok, check/allocar.tst: New files
522 implementing test cases for the new jit_allocar
523 interface.
524
525 * check/Makefile.am, check/lightning.c: Update for
526 the new test case and interface.
527
528 * doc/body.texi: Add documentation of the new
529 interface.
530
5312015-02-17 Paulo Andrade <pcpa@gnu.org>
532
533 * include/lightning/jit_x86.h, lib/jit_x86-cpu.c,
534 lib/jit_x86-x87.c: No longer make st(7) available.
535 Need to keep one x87 slots empty to avoid exceptions.
536 This has the side effect of no longer needing the
537 hackish emms instruction before a function call.
538
5392015-02-16 Paulo Andrade <pcpa@gnu.org>
540
541 * lib/lightning.c: Remove the jit_regno_patch bitfield
542 register fields before actual emit, as it is only really
543 used before emit, otherwise, on special conditions it
544 may consider live registers as dead during code emit.
545
5462015-02-15 Paulo Andrade <pcpa@gnu.org>
547
548 * lib/jit_x86-cpu.c, lib/jit_x86-sse.c, lib/jit_x86-x87.c:
549 Correct encoding of ldxr* stxr* in the x32 abi. If the
550 displacement register is negative, it would generate
551 a 64 bit instruction with a 32 bit unsigned displacement.
552
553 * check/ranger.tst, check/ranger.ok: New files, implementing
554 a test case for negative loads and stores. This is range.tst
555 converted to use registers instead of immediate offsets.
556
557 check/Makefile.am: Update for the new test case.
558
5592015-02-07 Paulo Andrade <pcpa@gnu.org>
560
561 * lib/jit_size.c: Preventively use at least 144 bytes
562 if JIT_INSTR_MAX is less than it. The logic is not
563 guaranteed to be 100% precise, it is mostly heuristics
564 to allocate a buffer with as close as possible size,
565 but a wrong value may cause code generation to write
566 past the end of the buffer.
567
5682015-02-03 Paulo Andrade <pcpa@gnu.org>
569
570 * lib/lightning.c: Correct the reason the bug in
571 simplify_stxi was not triggered before, it was due to
572 incorrectly resetting the value->code field, what was
573 causing it to never properly optimize:
574 stxi Im0 Rb0 Rt0
575 ldxi Rt1 Rb1 Im1
576 when Rb0 == Rb1, Rt0 == Rt1 and Im0 == Im1
577 There was another possible issue, that has been also
578 addressed in this commit, that would be the case of
579 Rbn == Rtn, where no redundancy removal is possible.
580
5812015-02-03 Paulo Andrade <pcpa@gnu.org>
582
583 * lib/lightning.c: Correct wrong check in simplify_stxi.
584 The test was incorrectly comparing the target register
585 and the displacement offset. This was a time bomb bug,
586 that would trigger in code like:
587 stxi Im0 Rb0 Rt0
588 stxi Im1 Rb1 Rt1
589 if Rb0 == Rb1 && Rt0 == Rt1 && Im0 == Rt1, that is,
590 the wrong check was Im0 == Rt1, instead of the supposed
591 Im0 == Imm1 (that was what the code mean't to do). It
592 was removing the second stxi assuming it was redundantly
593 generated; as that is not uncommon pattern on
594 translators generating jit.
595
5962015-02-02 Paulo Andrade <pcpa@gnu.org>
597
598 * configure.ac, include/lightning/jit_private.h,
599 lib/jit_aarch64.c, lib/jit_alpha.c, lib/jit_arm.c,
600 lib/jit_disasm.c, lib/jit_hppa.c, lib/jit_ia64.c,
601 lib/jit_mips.c, lib/jit_ppc.c, lib/jit_print.c,
602 lib/jit_s390.c, lib/jit_sparc.c, lib/jit_x86.c: Add a new
603 --enable-devel-disassembler option, that should be used
604 during development, or lightning debug. This option
605 intermixes previous jit_print and jit_disassemble
606 output, making it easier to visualize what lightning
607 call was used, and what code was generated.
608
6092015-01-31 Paulo Andrade <pcpa@gnu.org>
610
611 * lib/jit_arm-cpu.c, lib/jit_arm.c: Only limit to 24 bit
612 displacement non conditional jump in the same jit_state_t.
613
6142015-01-19 Paulo Andrade <pcpa@gnu.org>
615
616 * doc/body.texi: Reorder documentation, making jit_frame
617 and jit_tramp the lightning response to the need of
618 trampolines, continuations and tail call optimizations.
619 A pseudo code example of a factorial function was added.
620 Also added a section for description of the available
621 predicates.
622
623 * doc/fact.c: New file, implementing a simple example of
624 a translation of a trivial, recursive, tail call optimization
625 into lightning calls. This is the conversion to functional C
626 code of the example in doc/body.texi.
627
628 * doc/Makefile.am: Update for the next test case.
629
6302015-01-17 Paulo Andrade <pcpa@gnu.org>
631
632 * include/lightning.h, lib/jit_aarch64.c,
633 lib/jit_alpha.c, lib/jit_arm-vfp.c, lib/jit_arm.c,
634 lib/jit_hppa.c, lib/jit_ia64.c, lib/jit_mips.c,
635 lib/jit_ppc.c, lib/jit_s390.c, lib/jit_sparc.c,
636 lib/jit_x86.c: Add the new jit_arg_register_p predicate.
637 The predicate is expected to be used to know if an
638 argument is in a register, what would need special
639 handling if code that can overwrite non callee save
640 registers is executed.
641
642 * check/carg.c: New test case to check consistency and
643 expected usage of jit_arg_register_p.
644
645 * check/Makefile.am: Update for new test case.
646
6472015-01-17 Paulo Andrade <pcpa@gnu.org>
648
649 * include/lightning/jit_aarch64.h,
650 include/lightning/jit_alpha.h,

652 include/lightning/jit_hppa.h,
653 include/lightning/jit_mips.h,

661 lib/jit_ppc.c, lib/jit_s390.c,
662 lib/jit_sparc.c, lib/jit_x86.c: Remove jit_arg_reg_p and
663 jit_arg_f_reg_p from a public header, and define it only
664 on port specific files where an integer offset is used
665 to qualify an argument identifier. Exported code expects
666 an opaque pointer (but of jit_node_t* type) to "qualify"
667 an argument identifier.
668 This patch, and the code review/simplification done during
669 it also corrected some bugs:
670 o Inconsistent jit_arg_d value of double argument after 3
671 integer arguments in arm for jit_functions; tested, C
672 functions were being properly called.
673 o Inconsistent use of getarg_{f,d} and putarg*_{f,d} on
674 s390 (32-bit) that happened to not have a proper test
675 case, as it would only happen for jit functions, and
676 tested, called C functions had proper arguments.
677 o Corrected a "last minute" correction that did not go
678 to the committed version, and would not compile on hppa,
679 due to bad _jit_putargi_d prototype definition.
680
6812015-01-17 Paulo Andrade <pcpa@gnu.org>
682
683 * doc/body.texi: Correct wrong/outdated information for
684 hton*, pusharg* and ret*, and add missing documentation
685 for rsb*, qmul*, qdvi* and putarg*.
686
6872015-01-15 Paulo Andrade <pcpa@gnu.org>
688
689 * configure.ac, lib/jit_disasm.c: Rewrite workaround
690 to apparent problem to initialize powerpc disassembler.
691
6922015-01-15 Paulo Andrade <pcpa@gnu.org>
693
694 * include/lightning.h, lib/jit_aarch64.c,
695 lib/jit_alpha.c, lib/jit_arm.c, lib/jit_hppa.c,
696 lib/jit_ia64.c, lib/jit_mips.c, lib/jit_ppc.c,
697 lib/jit_s390.c, lib/jit_sparc.c, lib/jit_x86.c:
698 Implement jit_putarg*. It works as a mix of jit_getarg*
699 and jit_pusharg*, in the way that the first argument is
700 a register or immediate, and the second is a pointer
701 returned by jit_arg*. The use of the interface is to change
702 values of arguments to the current jit function.
703
704 * check/put.ok, check/put.tst: New test cases exercising
705 the new jit_putarg* interface.
706
707 * check/Makefile.am, check/lightning.c: Update for the
708 new test case and interface.
709
7102015-01-08 Paulo Andrade <pcpa@gnu.org>
711
712 * include/lightning/jit_s390.h, lib/jit_s390-cpu.c,
713 lib/jit_s390-fpu.c, lib/jit_s390-sz.c, lib/jit_s390.c:
714 Renamed s390x* files to s390*.
715
716 * check/float.tst, check/lightning.c, configure.ac,
717 include/lightning.h, include/lightning/Makefile.am,
718 lib/Makefile.am, lib/jit_s390.c, lib/jit_size.c,
719 lib/lightning.c: Update for renamed files.
720
7212015-01-08 Paulo Andrade <pcpa@gnu.org>
722
723 * include/lightning.h, include/lightning/jit_private.h,
724 include/lightning/jit_s390x.h, lib/jit_disasm.c,
725 lib/jit_s390x-cpu.c, lib/jit_s390x-fpu.c, lib/jit_s390x-sz.c,
726 lib/jit_s390x.c, lib/jit_size.c, lib/lightning.c:
727 Add support for generating jit for s390 32 bit. This change
728 also removed %f15 from the list of temporaries fpr registers;
729 it was not being used, but if were, it would corrupt the
730 stack frame because the spill address would overwrite grp
731 offsets.
732
7332014-12-26 Paulo Andrade <pcpa@gnu.org>
734
735 * lib/jit_ppc-cpu.c, lib/jit_ppc.c: Correct some endianess issues
736 on the powerpc le backend.
737
7382014-12-26 Paulo Andrade <pcpa@gnu.org>
739
740 * lib/jit_ppc-cpu.c: Add mcrxr instruction emulation,
741 as this instruction has been phased out, and should be
742 implemented as a kernel trap.
743
7442014-12-26 Paulo Andrade <pcpa@gnu.org>
745
746 * lib/jit_arm.c: Better check for need to flush constants
747 before the pool being no longer reachable.
748
7492014-12-25 Paulo Andrade <pcpa@gnu.org>
750
751 * include/lightning.h: Split jit_htonr in the new 3 interfaces
752 jit_htonr_us, jit_htonr_ui and jit_htonr_ul, the later only
753 available on 64 bit. The plain/untyped jit_htonr macro call
754 maps to the wordsize one.
755 * lib/jit_aarch64-cpu.c, lib/jit_aarch64-sz.c, lib/jit_aarch64.c,
756 lib/jit_alpha-cpu.c, lib/jit_alpha-sz.c, lib/jit_alpha.c,

764 lib/jit_x86-cpu.c, lib/jit_x86-sz.c, lib/jit_x86.c:
765 Update backends for the new jit_htonr*.
766 * check/lightning.c, lib/jit_names.c, lib/lightning.c:
767 Update for the new jit_htonr* interfaces.
768 * check/Makefile.am: Update for new test cases.
769 * check/hton.ok, check/hton.tst: New test cases.
770
7712014-12-24 Paulo Andrade <pcpa@gnu.org>
772
773 * include/lightning/jit_private.h, include/lightning/jit_x86.h,
774 lib/jit_disasm.c, lib/jit_x86-cpu.c, lib/jit_x86-sse.c,
775 lib/jit_x86-sz.c, lib/jit_x86-x87.c, lib/jit_x86.c,
776 size.c: Implement support for the x32 abi. Built and
777 tested on Gentoo default/linux/amd64/13.0/x32 profile.
778
7792014-12-24 Paulo Andrade <pcpa@gnu.org>
780
781 * lib/jit_names.c: Add missing rsbi_f and rsbi_d strings.
782
7832014-12-21 Paulo Andrade <pcpa@gnu.org>
784
785 * lib/jit_arm.c: Call __clear_cache for every page.
786 This should only be required for older boards or
787 toolchain setup, but has been reported to be required
788 for lightning at some point.
789
7902014-12-21 Paulo Andrade <pcpa@gnu.org>
791
792 * lib/jit_arm.c: Correct check to guard overflow of index
793 of constants from program counter.
794
7952014-11-24 Paulo Andrade <pcpa@gnu.org>
796
797 * lib/lightning.c: Remove an optimization to calee save
798 registers that may incorrectly remove a jit_movr under
799 special conditions.
800
8012014-11-20 Paulo Andrade <pcpa@gnu.org>
802
803 * include/lightning/jit_ppc.h, lib/jit_ppc-cpu.c,
804 lib/jit_ppc.c: Add initial powerpc le support.
805
8062014-11-20 Paulo Andrade <pcpa@gnu.org>
807
808 * lib/jit_disasm.c: Change thumb or arm disassemble based on
809 jit code before disassembly.
810
811 * lib/jit_arm-cpu.c: Correct reversed arguments to LDRD and
812 STRD instructions, and correct checking for support of those.
813
814 * lib/jit_arm-swf.c: Correct wrong use of LDRD and STRD and
815 only use those if the register is even.
816
817 * check/check.arm.swf.sh, check/check.arm4.swf.sh: New files
818 to test LDRD and STRD, as well as the alternate code path
819 when those are not available, in the .arm4. test case.
820
821 * check/Makefile.am: Update for the new test cases.
822
8232014-11-08 Paulo Andrade <pcpa@gnu.org>
824
825 * include/lightning/jit_private.h, lib/jit_aarch64.c,
826 lib/jit_alpha.c, lib/jit_arm.c, lib/jit_hppa.c,
827 lib/jit_ia64.c, lib/jit_mips.c, lib/jit_ppc.c,
828 lib/jit_s390x.c, lib/jit_sparc.c, lib/jit_x86.c:
829 Implement a private jit_flush call, that flushes
830 the cache, if applicable, aligning down to the
831 previous and up to the next page boundary.
832
8332014-11-08 Paulo Andrade <pcpa@gnu.org>
834
835 * check/ctramp.c: New file. It just repeats the test
836 of tramp.tst, but using two jit_state_t, what should
837 test possible issues with two contexts, and also validate
838 jit_tramp works on backends with function descriptions.
839
840 * check/Makefile.am: Update for new test case.
841
8422014-11-03 Paulo Andrade <pcpa@gnu.org>
843
844 * include/lightning/jit_mips.h: Do not make the t9 register
845 JIT_R11 (or JIT_R7 for n32 or n64 abi) available. Previously
846 it cause problems if one expects it to not be changed in a
847 function call. For example, calling a jit function, where it
848 really does not need to be changed.
849
8502014-10-26 Paulo Andrade <pcpa@gnu.org>
851
852 * lib/jit_aarch64.c, lib/jit_alpha.c, lib/jit_arm.c,
853 lib/jit_hppa.c, lib/jit_ia64.c, lib/jit_mips.c, lib/jit_ppc.c,
854 lib/jit_s390x.c, lib/jit_sparc.c, lib/jit_x86.c: Add an
855 assertion to all code generation "drivers" to ensure
856 _jitc->regarg is empty or in an expected state, after
857 translation of a lightning instruction to native code.
858 This change was a brute force test to find out other cases
859 of a temporary not being release (like was happening with
860 _bmsi and _bmci on x86), but no other case was found,
861 after running make check, with assertions enabled, on all
862 backends.
863
8642014-10-26 Paulo Andrade <pcpa@gnu.org>
865
866 * lib/jit_x86-cpu.c: Correct a register allocation leak in
867 _bmsi and _bmci.
868
8692014-10-25 Paulo Andrade <pcpa@gnu.org>
870
871 * lib/jit_disasm.c: Do not cause an fatal error if init_jit
872 fails in the jit_init_debug call.
873
8742014-10-24 Paulo Andrade <pcpa@gnu.org>
875
876 * lib/jit_ia64.c, lib/jit_ppc.c: Correct handling of function
877 descriptor when first prolog is a jit_tramp prolog. The
878 test case was using the same jit_context_t, so was not
879 triggering this condition.
880
881 * lib/jit_ppc-cpu.c: Properly handle jump displacements that
882 do not fit on 24 powerpc. This required changing from previous
883 "mtlr reg, blr" to "mtctr reg, bctr" to properly handle
884 the logic to "hide" function descriptors, but that would
885 also be required as the proper jit_jmpr when/if implementing
886 optimizations to leaf functions (was working with blr because
887 it is saved/reloaded in prolog/epilog).
888
8892014-10-21 Paulo Andrade <pcpa@gnu.org>
890
891 * include/lightning.h, lib/lightning.c: Add three predicates
892 to query information about labels. jit_forward_p(label)
893 will return non zero if the label is "forward", that is
894 need a call to jit_link(label), jit_indirect_p(label)
895 that returns non zero if the label was created with the
896 jit_indirect() call, and jit_target_p(label) that will
897 return non zero if there is at least one jump patched
898 to land at that label.

901
902 * check/range.ok, check/range.tst: New test case designed
903 to catch incorrect code generation, usually due to incorrect
904 test of immediate size. The test checks a large amount of
905 encodings in "power of two" boundaries. This test exorcises
906 a significant amount of code paths that was previously not
907 tested.
908
909 * check/Makefile.am: Add range test to make check target.
910
911 * lib/jit_aarch64-cpu.c: Correct wrong address calculation
912 for stxi_c, stxi_s, stxi_i and stxi_l when the offset is
913 too large.
914
915 * lib/jit_mips-fpu.c: Correct wrong size test to check if
916 an immediate can be encoded in a float or double store.
917
918 * lib/jit_s390x-cpu.c: Correct inverted encoding to stxi_s
919 when the offset cannot be encoded, and fallbacks to an
920 alternate encoding in 2 instructions.
921
9222014-10-17 Paulo Andrade <pcpa@gnu.org>
923
924 * check/alu_rsb.ok, check/alu_rsb.tst: New files implementing
925 tests for jit_rsb*.
926
927 * check/Makefile.am, check/lightning.c, include/lightning.h,

941 lib/jit_x86-sse.c, lib/jit_x86-sz.c, lib/jit_x86-x87.c,
942 lib/jit_x86.c, lib/lightning.c: Implement jit_rsb*. This
943 was a missing lightning 1.x interface, that on most
944 backends is synthesized, but on a few backends (hppa and ia64),
945 it can generate better code as on those there is, or the
946 only instruction with an immediate is in "rsb" format
947 (left operand).
948
9492014-10-17 Paulo Andrade <pcpa@gnu.org>
950
951 * lib/jit_names.c: New file with single definition of string
952 representation of lightning IR codes.
953
954 * size.c: Modified to append the code name in a C comment
955 after the maximum instruction size.
956
957 * lib/jit_print.c: Minor change to not duplicate jit_names.c
958 contents.
959
960 * lib/jit_aarch64-sz.c, lib/jit_alpha-sz.c, lib/jit_arm-sz.c,
961 lib/jit_hppa-sz.c, lib/jit_ia64-sz.c, lib/jit_mips-sz.c,
962 lib/jit_ppc-sz.c, lib/jit_s390x-sz.c, lib/jit_sparc-sz.c,
963 lib/jit_x86-sz.c: Rewritten to add string representation of
964 IR codes in a C comment.
965
9662014-10-14 Paulo Andrade <pcpa@gnu.org>
967
968 * lib/jit_aarch64-cpu.c, lib/jit_alpha-cpu.c, lib/jit_arm-cpu.c,
969 lib/jit_hppa-cpu.c, lib/jit_mips-cpu.c, lib/jit_ppc-cpu.c,
970 lib/jit_sparc-cpu.c: Implement or correct the internal
971 nop(count) call that receives an argument that tells the
972 modulo bytes to align the code for the next instruction.
973
974 * include/lightning.h, lib/lightning.c, lib/jit_aarch64.c,
975 lib/jit_alpha.c, lib/jit_arm.c, lib/jit_hppa.c, lib/jit_ia64.c,
976 lib/jit_mips.c, lib/jit_ppc.c, lib/jit_s390x.c, lib/jit_sparc.c,
977 lib/jit_x86.c: Implement the new jit_align() call that receive
978 an argument, that tells the modulo, in bytes, to align the
979 next instruction. In most backends the only value that makes
980 a difference is a value that matches sizeof(void*), as all
981 other values usually are already automatically aligned in
982 labels, but not guaranteed to be aligned at word size bytes.
983
984 * check/align.ok, check/align.tst: New files, implementing
985 a simple test for the new jit_align() interface.
986
987 * check/Makefile.am, check/lightning.c, lib/jit_aarch64-sz.c,
988 lib/jit_alpha-sz.c, lib/jit_arm-sz.c, lib/jit_hppa-sz.c,
989 lib/jit_ia64-sz.c, lib/jit_mips-sz.c, lib/jit_ppc-sz.c,
990 lib/jit_print.c, lib/jit_s390x-sz.c, lib/jit_sparc-sz.c,
991 lib/jit_x86-sz.c: Update for the new jit_code_align code and
992 the jit_align() interface.
993
9942014-10-13 Paulo Andrade <pcpa@gnu.org>
995
996 * include/lightning.h, lib/jit_size.c, size.c: Use a
997 symbolic value for the last IR code.
998
9992014-10-12 Paulo Andrade <pcpa@gnu.org>
1000
1001 * include/lightning.h, include/lightning/jit_private.h,
1002 lib/jit_aarch64-cpu.c, lib/jit_alpha-cpu.c, lib/jit_arm-cpu.c,
1003 lib/jit_hppa-cpu.c, lib/jit_ia64-cpu.c, lib/jit_mips-cpu.c,
1004 lib/jit_ppc-cpu.c, lib/jit_s390x-cpu.c, lib/jit_sparc-cpu.c,
1005 lib/jit_x86-cpu.c, lib/lightning.c: Implement the new
1006 jit_frame and jit_tramp interfaces, that allow writing
1007 trampoline like calls, where a single dispatcher jit buffer
1008 is written, and later other jit buffers are created, with
1009 the same stack frame layout as the dispatcher. This is the
1010 logic that GNU Smalltalk used in lightning 1.x, and is required
1011 to make a sane port for lighting 2.x.
1012
1013 * jit_ia64-cpu.c: Implement support for jit_frame and jit_tramp,
1014 and also correct wrong encoding for B4 instructions, that
1015 implement jmpr, as well as correct reverse logic in _jmpr,
1016 that was moving the branch register to the jump register,
1017 and not vice-versa.
1018 Also, if a stack frame is to be assumed, always assume it may
1019 call a function with up to 8 arguments, regardless of the
1020 hint frame argument.
1021
1022 * lib/jit_arm.c: Add a new must_align_p() interface to ensure
1023 function prologs are always aligned. This condition was
1024 previously always true, somewhat by accident, but with
1025 jit_tramp it is not guaranteed.
1026
1027 * jit_ia64-cpu.c: lib/jit_ppc.c: Add minor special handling
1028 required to implement jit_tramp, where a function descriptor
1029 should not be added before a prolog, as jit_tramp means omit
1030 prolog.
1031
1032 * check/lightning.c: Update test driver for the new interfaces.
1033
1034 * check/Makefile.am, check/tramp.tst, check/tramp.ok: Add
1035 a simple test and example of the jit_frame and jit_tramp
1036 usage implementing a simple Fibonacci function using a
1037 simulation of an interpreter stack and how it would handle
1038 state in language specific variables.
1039
1040 * doc/body.texi: Add documentation for jit_frame and
1041 jit_tramp.
1042
10432014-09-29 Paulo Andrade <pcpa@gnu.org>
1044
1045 * lib/jit_aarch64.c, lib/jit_alpha.c, lib/jit_arm.c,
1046 lib/jit_hppa.c, lib/jit_ia64.c, lib/jit_mips.c,
1047 lib/jit_ppc.c, lib/jit_s390x.c, lib/jit_sparc.c,
1048 lib/jit_x86.c, lib/lightning.c: Allow jit_jmpi on a
1049 target that is not a node. This may lead to hard to
1050 debug code generation, but is a required feature for
1051 certain generators, like the ones that used lightning
1052 1.2x. Note that previously, but not really well
1053 documented, it was instructed to use:
1054 jit_movi(rn, addr); jit_jmpr(rn);
1055 but now, plain:
1056 jit_patch_abs(jit_jmpi(), addr);
1057 should also work.
1058
10592014-09-24 Paulo Andrade <pcpa@gnu.org>
1060
1061 * lib/jit_x86-sz.c: Generate information about instruction
1062 lengths for more precise calculation of buffer size on
1063 Windows x64. This change is specially important because
1064 the maximum instruction length is larger than other
1065 systems, what could cause an out of bounds write on
1066 special conditions without this update.
1067
10682014-09-24 Paulo Andrade <pcpa@gnu.org>
1069
1070 * check/lightning.c: Add workaround to conflicting global
1071 optind variable in cygwin binutils that have an internal
1072 getopt* implementation.
1073
1074 * lib/jit_x86-cpu.c: Add a simple define ffsl ffs if building
1075 for 32 bit and there is no ffsl function.
1076
10772014-09-24 Paulo Andrade <pcpa@gnu.org>
1078
1079 * check/lightning.c: Add a hopefully temporary kludge to not use
1080 sprintf and sscanf returned by dlsym. This is required to pass
1081 the varargs test.
1082
1083 * include/lightning/jit_private.h: Use symbolic name for first
1084 integer register argument, as this is different in sysv and
1085 win64 abi.
1086
1087 * include/lightning/jit_x86.h: Add conditionals and definitions
1088 for Windows x64 (under __CYGWIN__ preprocessor conditional).
1089
1090 * lib/jit_x86-cpu.c: Correct one instruction encoding bug, that
1091 was working by accident. Only use rax to rdx for some byte
1092 operations to work on compatibility mode (that is, to generate
1093 the proper encoding, instead of actually generating encoding
1094 for high byte registers, e.g. %bh).
1095 Add proper prolog and epilog for windows x64.
1096
1097 * lib/jit_x86-sse.c: Correct a swapped rex prefix for float
1098 operations.
1099
1100 * lib/jit_x86.c: Adjust to support Windows x64 abi.
1101
1102 * check/check.x87.nodata.sh: New file, previously used but that
1103 was missing git.
1104
11052014-09-07 Paulo Andrade <pcpa@gnu.org>
1106
1107 * lib/lightning.c: Mark all registers advertised as live, as
1108 per jit_callee_save_p as live whenever reaching a jump that
1109 cannot be tracked. This is a rethink of the previous commit,
1110 and is a better approach, otherwise there would not be much
1111 sense on relying on jit_callee_save_p if it could not be
1112 trusted.
1113
1114 * check/jmpr.tst, check/jmpr.ok: New files implementing a very
1115 simple test case, that would actually cause an assertion on
1116 code before the change to only mark as live when reaching a
1117 jump that could not tracked, the actually advertised as callee
1118 save registers.
1119
1120 check/Makefile.am: Update for new jmpr test case.
1121
11222014-09-01 Paulo Andrade <pcpa@gnu.org>
1123
1124 * lib/lightning.c: Do not mark all registers in unknown state
1125 as live on jit_jmpr, or jit_jmpi to an absolute address. Instead,
1126 treat it as a function call, and only consider JIT_Vn registers
1127 as possibly live.
1128
11292014-08-29 Paulo Andrade <pcpa@gnu.org>
1130
1131 * doc/body.texi: Add a proper info menu entry for
1132 GNU lightning.
1133
1134 * doc/version.texi: Regenerate.
1135
11362014-08-16 Paulo Andrade <pcpa@gnu.org>
1137
1138 * lib/jit_aarch64-cpu.c, lib/jit_aarch64-fpu.c,
1139 lib/jit_arm-cpu.c, lib/jit_arm-vfp.c,
1140 lib/jit_hppa-cpu.c, lib/jit_hppa-fpu.c,
1141 lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c,
1142 lib/jit_mips-cpu.c, lib/jit_mips-fpu.c,

1146 lib/jit_x86-cpu.c, lib/jit_x86-sse.c,
1147 lib/jit_x86-x87.c: Review generation of all branch
1148 instructions and always adds the jit_class_nospill
1149 bitfield for temporary registers that cannot be spilled
1150 because the reload would be after a conditional jump; the
1151 patch only adds an extra assertion. These conditions do
1152 not happen on documented lightning usage, but can happen
1153 if one uses the not exported jit_get_reg and jit_unget_reg
1154 calls and cause enough register starvation.
1155
11562014-08-16 Paulo Andrade <pcpa@gnu.org>
1157
1158 * lib/jit_alpha.c: Correct wrong bitmask of most argument
1159 float register arguments, that were being set as callee
1160 save instead of argument registers class.
1161
11622014-08-16 Paulo Andrade <pcpa@gnu.org>
1163
1164 * lib/jit_arm-sz.c: Regenerate table of known maximum
1165 instruction sizes for the software float fallback,
1166 that implements "virtual" float registers in the stack
1167 and operations as calls to libgcc.
1168
1169 * size.c: Correct typo in the generated jit_arm-sz.c file.
1170
11712014-08-10 Paulo Andrade <pcpa@gnu.org>
1172
1173 * include/lightning/jit_alpha.h, lib/jit_alpha-cpu.c,
1174 lib/jit_alpha-fpu.c, lib/jit_alpha-sz.c, lib/jit_alpha.c:
1175 New files implementing a lightning Alpha port. Thanks
1176 to Trent Nelson and snakebit.net staff for providing access
1177 to an Alpha system.
1178
1179 * check/float.tst, check/lightning.c, configure.ac,
1180 include/lightning.h, include/lightning/Makefile.am,
1181 include/lightning/jit_private.h, lib/Makefile.am,
1182 lib/jit_disasm.c, lib/jit_size.c, lib/lightning.c:
1183 Minor changes to adapt for the new Alpha port.
1184
11852014-08-10 Paulo Andrade <pcpa@gnu.org>
1186
1187 * lib/lightning.c: Always mark JIT_RET and JIT_FRET as
1188 live in a function epilog. This is required because
1189 on some ports a complex sequence, allocating one or more
1190 registers, may be required to jump from a ret* to the
1191 epilog, and the lightning api does not have annotations
1192 to know if a function returns a value, or the type of
1193 the return value.
1194
11952014-08-10 Paulo Andrade <pcpa@gnu.org>
1196
1197 * lib/lightning.c: Change the correct live bitmask of
1198 return registers after a function call in jit_update.
1199
12002014-08-10 Paulo Andrade <pcpa@gnu.org>
1201
1202 * lib/lightning.c: Change assertions to have an int
1203 result and correct a bad bit mask assertion.
1204
12052014-08-10 Paulo Andrade <pcpa@gnu.org>
1206
1207 * lib/jit_aarch64.c: Correct bad setup for assertion
1208 of consistency before a patch.
1209
12102014-08-10 Paulo Andrade <pcpa@gnu.org>
1211
1212 * lib/jit_mips-cpu.c: Correct typo in the jit_bmsr
1213 implementation that was using the wrong test result
1214 register.
1215
12162014-07-28 Paulo Andrade <pcpa@gnu.org>
1217
1218 * lib/jit_memory.c: Do not call free on NULL pointers.
1219
1220 * include/lightning/jit_private.h, lib/jit_note.c,
1221 lib/lightning.c: Add a wrapper to memcpy and memmove
1222 to not actually call those functions with a zero size
1223 argument, and likely also a null src or dst.
1224
12252014-07-27 Paulo Andrade <pcpa@gnu.org>
1226
1227 * include/lightning/jit_private.h, lib/jit_disasm.c,
1228 lib/lightning.c: Remove the global jit_progname variable.
1229 It was being only used in jit_init_debug, that is called
1230 from init_jit, so, just pass an argument.
1231
12322014-07-27 Paulo Andrade <pcpa@gnu.org>
1233
1234 * doc/body.texi: Add note that jit_set_memory_functions
1235 should be called before init_jit, because init_jit
1236 itself may call the memory wrappers.
1237
12382014-04-22 Paulo Andrade <pcpa@gnu.org>
1239
1240 * lib/jit_arm.c: Do not get confused with default settings
1241 if /proc is not mounted on Linux specific code path.
1242
12432014-04-09 Paulo Andrade <pcpa@gnu.org>
1244
1245 * include/lightning/jit_aarch64.h, include/lightning/jit_arm.h,
1246 include/lightning/jit_hppa.h, include/lightning/jit_ia64.h,
1247 include/lightning/jit_mips.h, include/lightning/jit_ppc.h,
1248 include/lightning/jit_private.h, include/lightning/jit_s390x.h,
1249 include/lightning/jit_sparc.h, include/lightning/jit_x86.h:
1250 Do not add jit_regset_t, JIT_RA0, and JIT_FA0 to the installed
1251 header file. These types and definitions are supposed to be
1252 only used internally.
1253
12542014-04-05 Paulo Andrade <pcpa@gnu.org>
1255
1256 * lib/jit_arm-cpu.c: Only adjust stack pointer in prolog if
1257 need stack space, that is, do not emit a nop instruction
1258 subtracting zero from the stack pointer.
1259
12602014-04-04 Paulo Andrade <pcpa@gnu.org>
1261
1262 * lib/jit_disasm.c: Correct a crash in the doc/printf example
1263 on arm due to releasing the data_info information in
1264 jit_clear_state. This is a special case for arm only, and
1265 actually, only armv5 or older uses the data_info buffer,
1266 or when forcing arm instruction set mode besides thumb
1267 available.
1268
12692014-12-03 Paulo Andrade <pcpa@gnu.org>
1270
1271 * doc/body.texi: Write detailed description and examples for
1272 jit_get_memory_functions, jit_set_memory_functions,
1273 jit_get_code, jit_set_code, jit_get_data and jit_set_data.
1274
12752014-12-03 Paulo Andrade <pcpa@gnu.org>
1276
1277 * include/lightning.h, include/lightning/jit_private.h,
1278 lib/lightning.c: Implement the new jit_set_data() interface,
1279 and the new jit_get_data() helper. Like jit_set_code(),
1280 jit_realize() should be called before jit_set_data().
1281 The most common usage should be jit_set_data(JIT_DISABLE_DATA
1282 | JIT_DISABLE_NOTE), to force synthesize any float/double
1283 constant in the stack and not generate any debug information.
1284
1285 * lib/jit_note.c: Minor change to debug note generation as
1286 now it uses an alternate temporary data buffer during constants
1287 and debug generation to accommodate the possibility of the user
1288 setting an alternate data buffer.
1289
1290 * lib/jit_hppa-fpu.c, lib/jit_s390x.c, lib/jit_s390x-cpu.c,
1291 lib/jit_s390x-fpu.c, lib/jit_sparc.c, lib/jit_sparc-fpu.c,
1292 lib/jit_x86-sse.c, lib/jit_x86-x87.c: Implement jit_set_data.
1293
1294 * lib/jit_hppa-sz.c, lib/jit_sparc-sz.c, lib/jit_x86-sz.c,
1295 lib/jit_s390x-sz.c: Update for several instructions that now
1296 have a different maximum length due to jit_set_data.
1297
1298 * lib/jit_mips-fpu.c: Implement jit_set_data, but missing
1299 validation on n32 and n64 abis (and/or big endian).
1300
1301 * lib/jit_mips-sz.c: Update for changes in o32.
1302
1303 * lib/jit_ppc-fpu.c: Implement jit_set_data, but missing
1304 validation on Darwin PPC.
1305
1306 * lib/jit_ppc-sz.c: Update for changes in powerpc 32 and
1307 64 bit.
1308
1309 * lib/jit_ia64-fpu.c: Implement untested jit_set_data.
1310
1311 * TODO: Add note to list ports that were not tested for the
1312 new jit_set_data() feature, due to no longer having access
1313 to them.
1314
1315 * check/nodata.c: New file implementing a simple test exercising
1316 several different conditions created by jit_set_data().
1317
1318 * check/check.nodata.sh: New file implementing a wrapper
1319 over the existing *.tst files, that runs all tests without
1320 using a data buffer for constants; only meaningful (and
1321 enabled) on architectures that used to store float/double
1322 constants on a read only data buffer.
1323
1324 * configure.ac, check/Makefile.am: Update for the new test
1325 cases.
1326
1327 * check/lightning.c: Implement the new "-d" option that
1328 sets an internal flag to call jit_set_data() disable
1329 constants and debug, that is, using only a pure code
1330 buffer.
1331
13322014-11-03 Paulo Andrade <pcpa@gnu.org>
1333
1334 * include/lightning.h, include/lightning/jit_private.h,
1335 lib/lightning.c: Implement the new jit_set_code() interface,
1336 that allows instructing lightning to use an alternate code
1337 buffer. The new jit_realize() function should be called
1338 before jit_set_code(), and usually call jit_get_code()
1339 to query the amount of bytes expected to be required for
1340 the code.
1341
1342 * lib/jit_size.c: Minor update to have less chances of
1343 miscalculating the code buffer by starting the counter
1344 with the size of the longest instruction instead of zero,
1345 as code emit fails if at any moment less than the longest
1346 instruction bytes are available.
1347
1348 * check/setcode.c: New file implementing some basic tests
1349 of the new jit_set_code() interface.
1350
1351 * check/Makefile.am: Update for newer test case.
1352
13532014-06-03 Paulo Andrade <pcpa@gnu.org>
1354
1355 * include/lightning.h, lib/lightning.c: Add the new
1356 jit_indirect() call, that returns a special label node,
1357 and tells lightning that the label may be the target of
1358 an indirect jump.
1359
1360 * doc/body.texi: Document the new jit_indirect() call, and
1361 add examples of different ways to create labels and branches.
1362
13632014-23-02 Paulo Andrade <pcpa@gnu.org>
1364
1365 * lib/jit_x86.c: Rewrite previous patch to inline save/restore
1366 because clobbering %ebx in x86 is treated as an error
1367 (jit_x86.c:239:5: error: PIC register clobbered by 'ebx' in 'asm').
1368
13692014-19-02 Paulo Andrade <pcpa@gnu.org>
1370
1371 * lib/jit_x86.c: Rewrite incorrect inline assembly that could
1372 truncate a variable in a callee save register. Now it simply
1373 tells gcc that the register is clobbered, instead of using a
1374 *32 bit* swap with a temporary variable. The problem only
1375 happens when compiling with optimization.
1376
13772014-19-02 Paulo Andrade <pcpa@gnu.org>
1378
1379 * include/lightning/jit_aarch64.h, include/lightning/jit_arm.h,
1380 include/lightning/jit_hppa.h, include/lightning/jit_ia64.h,
1381 include/lightning/jit_mips.h, include/lightning/jit_ppc.h,
1382 include/lightning/jit_s390x.h, include/lightning/jit_sparc.h,
1383 include/lightning/jit_x86.h: Change jit_regset_t to an
1384 unsigned type, to allow safe right shift.
1385
1386 * lib/lightning.c: Rewrite jit_regset_scan1 to allow easier
1387 compiler optimization.
1388
13892013-12-03 Paulo Andrade <pcpa@gnu.org>
1390
1391 * lib/jit_x86-x87.c: Correct wrong optimization when
1392 loading the log(2) constant.
1393
13942013-12-03 Paulo Andrade <pcpa@gnu.org>
1395
1396 * lib/jit_x86-cpu.c: Use the emms instruction before
1397 calling any function. This is particularly important
1398 when using c99 complex functions as it can easily
1399 overflow the x87 stack due to the way lightning uses
1400 the x87 stack as a flat register file.
1401
14022013-12-02 Paulo Andrade <pcpa@gnu.org>
1403
1404 * lib/jit_x86-x87.c: Correct wrong code generation due
1405 to comparing the base and not the value register with
1406 %st(0) in stxi_f.
1407
14082013-12-02 Paulo Andrade <pcpa@gnu.org>
1409
1410 * lib/jit_x86-x87.c, lib/jit_x86.c: Use 8 bytes aligned
1411 stack offset for float/double x87 to/from sse move.
1412
14132013-11-27 Paulo Andrade <pcpa@gnu.org>
1414
1415 * configure.ac, lib/jit_arm-swf.c, lib/jit_arm.c: Add
1416 changes that should at least allow building lightning
1417 on Apple iOS7.
1418
14192013-10-08 Paulo Andrade <pcpa@gnu.org>
1420
1421 * lib/jit_ppc-cpu.c: Correct wrong shortcut for ldxi_l with
1422 a zero offset, that was calling ldr_i instead of ldr_l.
1423
14242013-10-08 Paulo Andrade <pcpa@gnu.org>
1425
1426 * include/lightning/jit_arm.h, lib/jit_arm-cpu.c: Do not use
1427 by default load/store instructions that map to ldrt/strt.
1428 There is already the long displacement version for positive
1429 offsets, and when using a (shorter) negative offset it does
1430 not map to ldrt/strt. At least on qemu strt may cause
1431 reproducible, but unexpected SIGILL.
1432
14332013-10-08 Paulo Andrade <pcpa@gnu.org>
1434
1435 * lib/jit_arm-vfp.c: Correct wrong load/store offset
1436 calculation when the displacement is constant but too
1437 large to use an instruction with an immediate offset.
1438
14392013-10-07 Paulo Andrade <pcpa@gnu.org>
1440
1441 * check/self.c: Extend tests to validate jit_callee_save_p
1442 does not cause an assertion on valid arguments, and test
1443 extra registers defined on some backends.
1444
1445 * configure.ac: Do not ignore environment CFLAGS when
1446 checking if need to test runtime configurable options,
1447 like use x87 when sse2 is available, arm instruction set
1448 instead of thumb, etc.
1449
1450 * include/lightning/jit_arm.h: Correct wrong jit_f macro
1451 definition.
1452
519a9ea1 1453 * include/lightning/jit_ia64.h, include/lightning/jit_ppc.h:
4a71579b
PC
1454 Correct wrong jit_r macro definition.
1455
1456 * lib/jit_x86-x87.c, lib/jit_x86.c: Actually use the
1457 reserved stack space for integer to/from float conversion.
1458 The stack space was also changed to ensure it is 8 bytes
1459 aligned. Also, for Solaris x86 in 32 bit mode, an alternate
1460 truncr_d was implemented because for some reason it is
1461 failing with SIGILL if using the "fisttpl" instructions,
1462 that must be available on p6 or newer, but for the sake of
1463 making all tests pass, implement a 486 or newer sequence
1464 if "sun" is defined.
1465
14662013-10-03 Paulo Andrade <pcpa@gnu.org>
1467
1468 * include/lightning/jit_mips.h, lib/jit_mips-cpu.c,
1469 lib/jit_mips-sz.c, lib/jit_mips.c, size: Build and
1470 pass all test cases on Irix big endian mips using
1471 the 64 bit abi.
1472
14732013-10-02 Paulo Andrade <pcpa@gnu.org>
1474
1475 * include/lightning/jit_mips.h: Add proper mips abi detection.
1476
14772013-09-30 Paulo Andrade <pcpa@gnu.org>
1478
1479 * lib/jit_print.c: Do not crash if calling jit_print from
1480 gdb before actually emitting code.
1481
1482 * lib/lightning.c: Correct misplaced check for already
1483 visited blocks on conditional branches, what was preventing
1484 proper merge live bit masks of forward blocks.
1485
14862013-09-30 Paulo Andrade <pcpa@gnu.org>
1487
1488 * lib/jit_x86-cpu.c: Correct not properly tested case of using
1489 %r12 as index register, what was causing an invalid assertion.
1490 %r12 is mapped to the "extra" JIT_R3 register, and test cases
1491 only test "standard" lightning registers.
1492
14932013-09-28 Paulo Andrade <pcpa@gnu.org>
1494
1495 * lib/jit_ia64.c: Minor change to force collecting the maximum
1496 instruction length in the --enable-devel-get-jit-size build
1497 mode. The actual generated file did not change because the
1498 sampling was large enough that it had already collected proper
1499 information in the previously slightly buggy code (not forcing
1500 a sync of the instructions that could be combined).
1501
15022013-09-27 Paulo Andrade <pcpa@gnu.org>
1503
1504 * lib/jit_arm.c: Correct build when disassembler is
1505 disabled.
1506
15072013-09-25 Paulo Andrade <pcpa@gnu.org>
1508
1509 * lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c: Correct some
1510 off by one range checks (that were only accepting values
1511 one less than the maximum allowed) and an invalid test
1512 condition check that was forcing it to always use
1513 indirect jumps even when reachable with an immediate
1514 displacement.
1515
15162013-09-24 Paulo Andrade <pcpa@gnu.org>
1517
1518 * lib/jit_aarch64-sz.c, lib/jit_arm-sz.c, lib/jit_hppa-sz.c,
1519 lib/jit_ia64-sz.c, lib/jit_mips-sz.c, lib/jit_ppc-sz.c,
1520 lib/jit_s390x-sz.c, lib/jit_size.c, lib/jit_sparc-sz.c,
1521 lib/jit_x86-sz.c: New files implementing static tables
1522 with longest known instructions length generated to match
1523 a lightning instruction. These tables should make it easier
1524 to make it very unlikely to ever miscalculate, or by too
1525 much, the size of a code buffer.
1526
1527 * lib/jit_size.c: New file that aids to either collect
1528 jit code size information, or use the information depending
1529 on build options.
1530
1531 * size.c: New helper file that parses input for, and create
1532 an initial jit_$arch-sz.c file, that needs some minor edit
1533 for arches with multiple configurations.
1534
1535 * configure.ac, Makefile.am: Add the new, devel mode only
1536 --enable-devel-get-jit-size configure option, that sets
1537 compile time flags to collect jit code size information,
1538 that will be used as input for the "noinst size program".
1539
1540 * lib/jit_aarch64.c, lib/jit_arm.c, lib/jit_disasm.c,
1541 lib/jit_hppa.c, lib/jit_ia64.c, lib/jit_memory.c,
1542 lib/jit_mips.c, lib/jit_ppc.c, lib/jit_s390x.c,
1543 lib/jit_sparc.c, lib/jit_x86.c, lib/lightning.c: Minor
1544 changes for the --enable-devel-get-jit-size build mode,
1545 as well as the "production build mode" with jit code
1546 size information.
1547
15482013-09-14 Paulo Andrade <pcpa@gnu.org>
1549
1550 * include/lightning.h, lib/lightning.c: Add the new
1551 jit_pointer_p interface, that returns a boolean value
1552 telling if the pointer argument is inside the jit
1553 code buffer. This is useful to avoid the need to add
1554 extra labels and calls to jit_address to figure bounds
1555 of code buffer, and still keep internal data private.
1556
15572013-09-13 Paulo Andrade <pcpa@gnu.org>
1558
1559 * include/lightning.h, include/lightning/jit_private.h,
1560 lib/jit_note.c: Change the code argument of jit_get_note
1561 to a jit_pointer_t and make jit_get_note a public interface.
1562 It was intended so since start, as a way to map an offset
1563 in the code to a function name, file name and line number
1564 mapping.
1565
15662013-09-11 Paulo Andrade <pcpa@gnu.org>
1567
1568 * doc/body.texi: Correct reversed arguments in example of
1569 usage in a (possibly) multi threaded, multiple jit_state_t
1570 environments.
1571
1572 * include/lightning/jit_arm.h, include/lightning/jit_private.h,
1573 lib/jit_arm-cpu.c, lib/jit_arm.c: Make a previously, non
1574 documented, global state private to the related jit_state_t
1575 generating code.
1576
15772013-09-10 Paulo Andrade <pcpa@gnu.org>
1578
1579 * check/self.c, check/self.ok: New files implementing simple
1580 consistency check assertions. At first validating some macros
1581 that use values from different sources agree.
1582
1583 * check/Makefile.am: Update for the new test case.
1584
1585 * include/lightning.h, lib/lightning.c: Add the new
1586 jit_callee_save_p() call, that is intended to be used when
1587 writing complex code using lightning, so that one does not
1588 need to verify what backend is being used, or have access to
1589 private data, to query if a register is callee save or not;
1590 on several backends the scratch registers are actually callee
1591 save.
1592
1593 * include/lightning/jit_aarch64.h, include/lightning/jit_arm.h,
1594 include/lightning/jit_hppa.h, include/lightning/jit_mips.h,
1595 include/lightning/jit_ppc.h, include/lightning/jit_sparc.h,
1596 include/lightning/jit_x86.h: Add an explicit definition for
1597 JIT_R3-JIT_Rn, JIT_V3-JIT_Vn and JIT_F6-JIT_Fn when applicable.
1598 This allows one to write code based on "#if defined(JIT_XN)"
1599 and therefore, not need to check what is the current backend
1600 or have access to private data structures. This is particularly
1601 useful when writing virtual machines with several specialized,
1602 global registers.
1603
1604 * lib/jit_ia64.c: Properly flag the callee save general
1605 purpose registers as such, so that jit_callee_save_p() works
1606 as intended.
1607
16082013-09-10 Paulo Andrade <pcpa@gnu.org>
1609
1610 * check/lightning.c, configure.ac: Conditionally use the
1611 code written to workaround a bug in the Hercules emulator,
1612 as isnan and isinf are not available at least on HP-UX ia64.
1613
16142013-09-10 Paulo Andrade <pcpa@gnu.org>
1615
1616 * lib/jit_s390x-cpu.c: Spill/reload correct callee save
1617 float registers.
1618
16192013-09-10 Paulo Andrade <pcpa@gnu.org>
1620
1621 * lib/jit_hppa-cpu.c: Correct code to call a function stored
1622 in a register or a patched function address.
1623
16242013-09-10 Paulo Andrade <pcpa@gnu.org>
1625
1626 * lib/jit_ia64-cpu.c: Correct incorrect logic when restoring
1627 the value of the "r2" callee save register.
1628
16292013-08-29 Paulo Andrade <pcpa@gnu.org>
1630
1631 * lib/jit_arm-cpu.c, lib/jit_arm.c: Correct wrong test and update
1632 of the thumb offset information, when checking if needing to
1633 patch a jump from arm to thumb mode. The problem would happen when
1634 remapping the code buffer, and the new address being lower than
1635 the previous one.
1636
16372013-08-26 Paulo Andrade <pcpa@gnu.org>
1638
1639 * configure.ac: Extend FreeBSD test to also handle NetBSD.
1640
1641 * lib/jit_x86-cpu.c: Correct wrongly defined offset type of
1642 ldxi_ui. Problem detected when building on NetBSD.
1643
1644 * lib/lightning.c: Adjust code to handle NetBSD mremap,
1645 where arguments do not match Linux mremap.
1646
16472013-08-26 Paulo Andrade <pcpa@gnu.org>
1648
1649 * lib/jit_ppc.c: Correct C sequence point problem miscalculating
1650 the actual function address in a function descriptor. Problem
1651 happens with gcc 4.8.1 at least.
1652
16532013-08-11 Paulo Andrade <pcpa@gnu.org>
1654
1655 * lib/jit_s390x-cpu.c: Correct code checking if immediate
1656 fits instruction, but using the negated value.
1657
16582013-07-28 Paulo Andrade <pcpa@gnu.org>
1659
1660 * include/lightning/jit_s390x.h, lib/jit_s390x-cpu.c,
1661 lib/jit_s390x-fpu.c, lib/jit_s390x.c: New files
1662 implementing the new s390x port.
1663
1664 * configure.ac, include/lightning.h,
1665 include/lightning/Makefile.am,
1666 include/lightning/jit_private.h,
1667 lib/Makefile.am, lib/jit_disasm.c, lib/lightning.c:
1668 Minor adaptation for the new s390x backend.
1669
1670 * check/float.tst: Update for the s390x result of
1671 truncating +Inf to integer.
1672
1673 * check/qalu_mul.tst: Add extra test cases to better test
1674 high word of signed multiplication as the result is
1675 adjust from unsigned multiplication on s390x.
1676
16772013-07-28 Paulo Andrade <pcpa@gnu.org>
1678
1679 * check/lightning.c: Do not assume casting a double NaN or
1680 Inf to float will produce the expected float NaN or Inf.
1681 This is not true at least under s390x.
1682
16832013-07-28 Paulo Andrade <pcpa@gnu.org>
1684
1685 * check/check.arm.sh, check/check.sh, check/check.swf.sh,
1686 check/check.x87.sh: Properly check test programs output,
1687 not just rely on the test program self testing the results
1688 and not crashing.
1689
16902013-07-28 Paulo Andrade <pcpa@gnu.org>
1691
1692 * lib/jit_aarch64.c: Remove unused macros left from cut&paste
1693 of jit_arm.c.
1694
16952013-07-16 Paulo Andrade <pcpa@gnu.org>
1696
1697 * include/lightning/jit_aarch64.h, lib/jit_aarch64-cpu.c,
1698 lib/jit_aarch64-fpu.c, lib/jit_aarch64.c: New files
1699 implementing the new aarch64 port, as a new architecture,
1700 not as an expansion of the existing armv[4-7] port.
1701
1702 * check/lightning.c: Add aarch64 support and a small
1703 change to recognize character constants as immediate
1704 values.
1705
1706 * check/float.tst: Add aarch64 preprocessor conditionals
1707 to select proper expected value when converting [+-]Inf
1708 and NaN to integer.
1709
1710 * include/lightning/jit_arm.h, lib/jit_arm.c: Minor changes
1711 to better match the new aarch64 files.
1712
1713 * configure.ac, include/lightning.h,
1714 include/lightning/Makefile.am, include/lightning/jit_private.h,
1715 lib/Makefile.am, lib/lightning.c: Minor adjustments
1716 for the aarch64 port.
1717
17182013-07-08 Paulo Andrade <pcpa@gnu.org>
1719
1720 * NEWS, THANKS, configure.ac, doc/version.texi: Update for
1721 the 1.99a second alpha release.
1722
17232013-06-25 Paulo Andrade <pcpa@gnu.org>
1724
1725 * lib/jit_mips.c: Correct cut&paste error that caused wrong
1726 stack offset calculation for double arguments in stack in
1727 the o32 abi.
1728 Correct typo in the __LITTLE_ENDIAN macro name, that came
1729 from cut&paste error in the original typo in lib/jit_ppc.c.
1730
1731 * lib/jit_ia64.c, lib/jit_ppc.c: Correct typo in the
1732 __LITTLE_ENDIAN macro name.
1733
17342013-06-22 Paulo Andrade <pcpa@gnu.org>
1735
1736 * check/lightning.c, configure.ac, include/lightning.h,
1737 lib/lightning.c: Add tests and quirks to build/detect
1738 and/or work on Irix.
1739
1740 * include/lightning/jit_mips.h, lib/jit_mips-cpu.c,
1741 lib/jit_mips-fpu.c, lib/jit_mips.c: Adapt code to run
1742 in big endian mips, using the n32 abi.
1743
17442013-06-18 Paulo Andrade <pcpa@gnu.org>
1745
1746 * include/lightning.h: Minor extra preprocessor testing
1747 to "detect" byte order on x86 solaris, that now builds
1748 and pass all test cases.
1749
17502013-06-18 Paulo Andrade <pcpa@gnu.org>
1751
1752 * lib/jit_sparc-cpu.c: Correct compiler warning of value
1753 used before assignment. The usage is bogus as the api
1754 requires always patching jumps, but the random value used
1755 could cause an assertion due to invalid displacement.
1756
1757 * lib/jit_sparc.c: Always load and store double arguments
1758 in stack as 2 float loads or stores, for safety, as unaligned
1759 access is not allowed in Sparc Solaris.
1760
17612013-06-14 Paulo Andrade <pcpa@gnu.org>
1762
1763 * configure.ac: Force -mlp64 to CFLAGS on HP-UX ia64 port.
1764 It is the only supported mode, and expects gcc as C compiler.
1765
1766 * include/lightning.h, lib/jit_ia64-cpu.c, lib/jit_ia64.c:
1767 Correct ia64 port to work on HP-UX that runs it in big endian
1768 mode.
1769
17702013-06-10 Paulo Andrade <pcpa@gnu.org>
1771
1772 * lib/jit_hppa.c: Sanitize the cache synchronization inline
1773 assembly code that was doing twice the work and redundantly
1774 flushing the end address every loop iteration.
1775
17762013-06-09 Paulo Andrade <pcpa@gnu.org>
1777
1778 * configure.ac, check/Makefile.am, doc/Makefile.am: Do not
1779 explicitly link to -ldl, but instead autodetect the library
1780 with dlopen, dlsym, etc.
1781
1782 * check/lightning.c: Add workaround to apparently buggy
1783 getopt in HP-UX that sets optind to the wrong index, and
1784 use RTLD_NEXT on HP-UX instead of RTLD_DEFAULT to dlsym
1785 global symbols.
1786
1787 * include/lightning.h: Rework definitions of wordsize and
1788 byte order to detect proper values on HP-UX.
1789
1790 * lib/lightning.c: Minor correction to use MAP_ANONYMOUS
1791 instead of MAP_ANON on HP-UX.
1792
1793 * lib/jit_hppa.c: Float arguments must be passed on integer
1794 registers on HP-UX, not only for varargs functions.
1795 Add code to properly clear instruction cache. This was
1796 not required on Debian hppa port, but may have been working
1797 by accident.
1798
1799 * lib/jit_hppa-cpu.c: Follow pattern of HP-UX binaries and
1800 use bve,n instead of bv,n to return from functions.
1801
1802 * lib/jit_hppa-fpu.c: For some reason "fst? frX,rX,(rY)" did
1803 not work on the tested computer (HP-UX B.11.23 U 9000/785 HP-UX)
1804 so the code was changed, at first for __hpux only to add the
1805 base and offset register and use the instruction with an
1806 immediate (zero) offset.
1807
18082013-06-07 Paulo Andrade <pcpa@gnu.org>
1809
1810 * check/lightning.c, lib/jit_disasm.c, lib/jit_ppc-cpu.c,
1811 lib/jit_ppc-fpu.c, lib/jit_ppc.c, include/lightning.h,
1812 include/lightning/jit_ppc.h, include/lightning/jit_private.h:
1813 Adapt code to work on 32 bit AIX ppc using gcc. Most changes
1814 are basically to adapt the elf64 logic to 32 bit, as it does
1815 not use the same convention of 32 bit Darwin ppc.
1816
1817 * check/stack.tst: Add a fake memcpy function to the test
1818 case if running under AIX, as it is not available to dlsym.
1819
1820 * configure.ac: Check for getopt.h header, not available in
1821 AIX.
1822
18232013-06-01 Paulo Andrade <pcpa@gnu.org>
1824
1825 * include/lightning/jit_hppa.h, lib/jit_hppa-cpu.c,
1826 lib/jit_hppa-fpu.c, lib/jit_hppa.c: New files implementing
1827 the hppa port. Built on Debian Linux PA-RISC 2.0, 32 bit.
1828
1829 * check/float.tst: Add preprocessor for hppa expected
1830 values when converting NaN and +-Inf to an integer.
1831
1832 * check/ldst.inc: Ensure double load/store tests use an
1833 8 byte aligned address by default.
1834
1835 * lib/lightning.c: Correct a bug found during tests in
1836 the new port, where qmul* and qdiv* were not properly
1837 setting one of the result registers as modified in the
1838 function, what would be a problem if the only "write"
1839 usage were the qmul* or qdiv*.
1840
1841 * check/varargs.tst, check/varargs.ok: Add one extra
1842 interleaved integer/double test to validate proper code
1843 generation in the extra case.
1844
1845 * check/lightning.c, configure.ac, include/lightning.h,
1846 include/lightning/Makefile.am,
1847 include/lightning/jit_private.h, lib/Makefile.am,
1848 lib/jit_disasm.c: Update for the hppa port.
1849
18502013-04-27 Paulo Andrade <pcpa@gnu.org>
1851
1852 * check/varargs.tst: Correct misplaced .align directive
1853 that was causing the double buffer to not be aligned at
1854 8 bytes.
1855 * lib/jit_ia64-cpu.c:
1856 Properly implement abi for excess arguments passed on
1857 stack.
1858 Simplify load/store with immediate displacement argument
1859 with zero value.
1860 Simplify some calls to "subi" changing to "addi" with
1861 a negative argument.
1862 Remove some #if 0'ed code, that could be useful in
1863 special conditions, but the most useful one would be
1864 to "optimize" "static" jit functions, but for the sake
1865 of simplicity, jit functions are implemented in a way
1866 that can be passed back to C code as C function pointers.
1867 Add an attribute to prototypes of several unused functions.
1868 These functions are defined for the sake of implementing all
1869 Itanium documented instructions, but a significant amount of
1870 them is not used by lightning.
1871 * lib/jit_ia64-fpu.c: Simplify load/store with zero immediate
1872 displacement and add unused attribute for functions not used
1873 by lightning, but required to provide macros implementing all
1874 Itanium documented instructions.
1875 * lib/jit_ia64.c: Update for the properly implemented abi
1876 for stack arguments.
1877 * lib/lightning.c: Mark an unused function as such.
1878
18792013-04-27 Paulo Andrade <pcpa@gnu.org>
1880
1881 lib/jit_ia64-cpu.c:
1882 Correct immediate range check of integer comparisons when
1883 inverting arguments.
1884 Correct gei_u that was not decrementing immediate when
1885 inverting arguments.
1886 Correct b?add* and b?sub* that were not properly updating
1887 the result register.
1888
18892013-04-27 Paulo Andrade <pcpa@gnu.org>
1890
1891 * lib/jit_ia64-cpu.c: Correct wrong mapping of 2 instructions
1892 in "M-, stop, M-, stop" translation, that was ignoring the
1893 last stop (implemented as a nop I- stop).
1894
1895 * lib/jit_ia64-fpu.c: Properly implement fnorm.s and fnorm.d,
1896 as well as the proper integer to float or double conversion.
1897
18982013-04-27 Paulo Andrade <pcpa@gnu.org>
1899
1900 * lib/jit_ia64-cpu.c: Correct bogus implementation of ldr_T
1901 for signed integers, that was using ld1.s, ld2.s and ld4.s.
1902 The ".s" stands for speculative load, not sign extend.
1903
1904 * lib/jit_ia64-fpu.c: Correct bogus implementation of ldxr_T
1905 for float and double. The third (actually, second) argument
1906 is indeed added to the base register, but the base register
1907 is modified. The actual M7 implementation was already correct,
1908 just the ldxr_f and ldxr_d implementation that was kept in
1909 a prototype state, misinterpreting what M7 does.
1910
19112013-04-27 Paulo Andrade <pcpa@gnu.org>
1912
1913 * lib/jit_ia64-cpu.c: Correct X2 pattern matching by preventing
1914 it to attempt to require a stop between the L and the X
1915 instruction; that is, check the registers and predicates
1916 before emitting the L instruction, not after.
1917
1918 * lib/jit_ia64-fpu.c: Slightly simplify and correct
1919 divr_f and divrd_d implementation.
1920
1921 * check/lightning.c: Add __ia64__ preprocessor define
519a9ea1 1922 on Itanium.
4a71579b
PC
1923
1924 * check/alu.inc, check/clobber.tst, check/float.tst: Define
1925 several macros conditionally to __ia64__. This is required
1926 because __ia64__ jit generation can use way too many memory,
1927 due to not implementing instruction reordering to avoid
1928 as much as possible "stops", what causes way too many nops
1929 to be generated, as well as the fact that division and
1930 remainder requires function calls, and float division
1931 requires significant code to implement.
1932
19332013-04-27 Paulo Andrade <pcpa@gnu.org>
1934
1935 * include/lightning.h: Add new backend specific movr_w_d,
1936 movr_d_w and movi_d_w codes as helpers to ia64 varargs
1937 functions arguments.
1938
1939 * lib/jit_ia64-cpu.c:
1940 Correct wrong encoding of A5 small integers.
1941 Correct define of "mux" instruction modifiers.
1942 Correct ordering of arguments and predicates of cmp_xy
1943 implementation with immediate arguments; like most other
1944 codes with an immediate, the immediate is the second, not
1945 the third argument.
1946
1947 * lib/jit_ia64-fpu.c: Actual implementation of the code
1948 to move to/from gpr to/from fpr, to implement varargs abi.
1949
1950 * lib/jit_ia64.c: Make fpr argument registers not allocatable
1951 as temporaries, no need for the extra checks when there are
1952 plenty registers.
1953
1954 * lib/jit_print.c, lib/lightning.c: Minor updates for the
1955 new movr_w_d, movr_d_w and movi_d_w codes.
1956
19572013-04-26 Paulo Andrade <pcpa@gnu.org>
1958
1959 * lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c: Correct code to
1960 also insert a stop to break an instruction group if a
1961 register is written more than once in the same group.
1962 This may happen if a register is argument and result of
1963 some lightning call (not a real instruction). The most
1964 common case should be code in the pattern:
1965 movl rn=largenum
1966 ...
1967 mov rn=smallnum
1968 where "rn" would end up holding "largenum".
1969 But the problem possibly could happen in other circumstances.
1970
19712013-04-26 Paulo Andrade <pcpa@gnu.org>
1972
1973 * include/lightning/jit_ia64.h, lib/jit_ia64-cpu.c,
1974 lib/jit_ia64-fpu.c, lib/jit_ia64.c:
1975 Relocate JIT_Rn registers to the local registers, as, like
1976 float registers, div/rem and sqrt are implemented as function
1977 calls, and may overwrite non saved scratch registers.
1978 Change patch_at to receive a jit_code_t instead of a
1979 jit_node_t, so that it is easier to "inline" patches when
1980 some instruction requires complex code to implement, e.g.
1981 uneq and ltgt.
1982 Correct arguments to FMA and FMA like instructions that,
1983 due to a cut&paste error were passing the wrong argument
1984 to the related F- implementation function.
1985 Rewrite ltgt to return the proper result if one (or both)
1986 of the arguments is unordered.
1987
19882013-04-26 Paulo Andrade <pcpa@gnu.org>
1989
1990 * include/lightning/jit_ia64.h, include/lightning/jit_private.h,
1991 lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c, lib/jit_ia64.c,
1992 lib/lightning.c: Rework code to detect need of a "stop" to
1993 also handle predicates, as if a predicate is written, it
1994 cannot be read in the same instruction group.
1995 Use a single jit_regset_t variable for all registers when
1996 checking need for a stop (increment value by 128 for
1997 float registers).
1998 Correct wrong "subi" implementation, as the code executed
1999 is r0=im-r1, not r0=r1-im.
2000 Use standard lightning 6 fpr registers, and rework to
2001 use callee save float registers, that may be spill/reloaded
2002 in prolog/epilog. This is required because some jit
2003 instructions implementations need to call functions; currently
2004 integer div/mod and float sqrt, what may change the value of
2005 scratch float registers.
2006 Rework point of "sync" of branches that need to return a
2007 patch'able address, because the need for a "stop" before a
2008 predicate read causes all branches to be the instruction
2009 in slot 0, as there is no template to "stop" and branch
2010 in the same instruction "bundle".
2011
20122013-04-25 Paulo Andrade <pcpa@gnu.org>
2013
2014 * include/lightning/jit_ia64.h, lib/jit_ia64-cpu.c,
2015 lib/jit_ia64-fpu.c, lib/jit_ia64.c: New files implementing
2016 the basic infrastructure of an Itanium port. The code
2017 compiles and can generate jit for basic hello world like
2018 functions.
2019
2020 * check/lightning.c, configure.ac, include/lightning.h,
2021 include/lightning/Makefile.am, include/lightning/jit_private.h,
2022 lib/Makefile.am, lib/lightning.c: Update for the Itanium
2023 port.
2024
2025 * lib/jit_mips-cpu.c, lib/jit_mips.c: Correct typo and
2026 make the jit_carry register local to the jit_state_t.
2027 This matches code reviewed in the Itanium port, that
2028 should use the same base logic to handle carry/borrow.
2029
20302013-04-10 Paulo Andrade <pcpa@gnu.org>
2031
2032 * include/lightning/jit_private.h, lib/jit_arm.c,
2033 lib/jit_mips-cpu.c, lib/jit_mips.c, lib/jit_ppc-cpu.c,
2034 lib/jit_ppc.c, lib/jit_print.c, lib/jit_sparc-cpu.c,
2035 lib/jit_sparc.c, lib/jit_x86-cpu.c, lib/jit_x86.c,
2036 lib/lightning.c: Change all jit_regset macros to take
2037 a pointer argument, to avoid structure copies when
2038 adding a port to an architecture with more than 64
2039 registers.
2040
20412013-04-08 Paulo Andrade <pcpa@gnu.org>
2042
2043 * lib/jit_arm.c, lib/jit_ppc.c: Do not rely on __clear_cache
2044 aligning to the next page boundary the end argument. It may
2045 actually truncate it.
2046
20472013-03-29 Paulo Andrade <pcpa@gnu.org>
2048
2049 * include/lightning/jit_private.h, lib/jit_arm.c, lib/jit_memory.c,
2050 lib/jit_mips.c, lib/jit_ppc.c, lib/jit_sparc.c, lib/jit_x86.c,
2051 lib/lightning.c: Do not start over jit generation if can grow
2052 the code buffer with mremap without moving the base pointer.
2053
20542013-03-29 Paulo Andrade <pcpa@gnu.org>
2055
2056 * lib/jit_memory.c: Implement a simple memory allocation wrapper
2057 to allow overriding calls to malloc/calloc/realloc/free, as well
2058 as ensuring all memory containing pointers is zero or points to
2059 allocated memory.
2060
2061 * include/lightning.h, include/lightning/jit_private.h: Definitions
2062 for the memory allocation wrapper.
2063
2064 * lib/Makefile.am: Update for new jit_memory.c file.
2065
2066 * lib/jit_arm.c, lib/jit_disasm.c, lib/jit_mips.c, lib/jit_note.c,
2067 lib/jit_ppc.c, lib/jit_sparc.c, lib/jit_x86.c, lib/lightning.c:
2068 Use the new memory allocation wrapper code.
2069
20702013-03-22 Paulo Andrade <pcpa@gnu.org>
2071
2072 * configure.ac, include/lightning/jit_private.h, lib/lightning.c:
2073 Remove dependency on gmp. Only a simple bitmap was required, and
2074 that was not enough reason to force linking to gmp and possible
2075 complications caused by it.
2076
20772013-03-10 Paulo Andrade <pcpa@gnu.org>
2078
2079 * include/lightning.h: Add check for __powerpc__ defined
2080 in Linux, while Darwin defines __ppc__.
2081
2082 * include/lightning/jit_ppc.h: Adjust register definitions
2083 for Darwin 32 bit and Linux 64 bit ppc usage and/or ABI.
2084
2085 * include/lightning/jit_private.h: Add proper check for
2086 Linux __powerpc__ and an data definition for an workaround
2087 to properly handle code that starts with a jump to a "main"
2088 label.
2089
2090 * lib/jit_disasm.c: Add extra disassembler initialization
2091 for __powerpc64__.
2092
2093 * lib/jit_ppc-cpu.c: Add extra macros and functions, and
2094 correct/adapt previous ones to handle powerpc64.
2095
2096 * lib/jit_ppc-fpu.c: Adapt for 64 bit wordsize. Basically
2097 add conversion from/to int32/int64 and proper handling of
2098 load/store offsets too large for 32 bit.
2099
2100 * lib/jit_ppc.c: Add calls to 64 bit codes and adaptation
2101 for the PowerPC 64 bit Linux ABI.
2102
2103 * lib/jit_arm.c, lib/jit_mips.c, lib/jit_sparc, lib/jit_x86.c,
2104 lib/lightning.c: Correct off by one error when restarting jit
2105 of a function due to finding too late that needs to spill/reload
2106 some register. Problem was found by accident on a very special
2107 condition during PowerPC 64 code adaptation.
2108
21092013-03-08 Paulo Andrade <pcpa@gnu.org>
2110
2111 * check/lightning.c: Add missing ppc preprocessor definition.
2112
21132013-03-06 Paulo Andrade <pcpa@gnu.org>
2114
2115 * check/float.tst: Comment out the int to negative infinity
2116 test in mips for the moment because not all Loongson agrees
2117 on the result.
2118
2119 * lib/jit_disasm.c: Add a test instead of an assertion
2120 when loading symbols for disassembly due to a failure with
2121 a simple binutils build in Debian mipsel64.
2122
21232013-03-06 Paulo Andrade <pcpa@gnu.org>
2124
2125 * include/lightning/jit_private.h, lib/jit_arm-cpu.c,
2126 lib/jit_arm.c, lib/jit_disasm.c, lib/jit_mips-cpu.c,
2127 lib/jit_mips.c, lib/jit_note.c, lib/jit_ppc-cpu.c,
2128 lib/jit_ppc.c, lib/jit_print.c, lib/jit_sparc-cpu.c,
2129 lib/jit_sparc.c, lib/jit_x86-cpu.c, lib/jit_x86.c,
2130 lib/lightning.c: Add an extra structure for data storage
2131 during jit generation, and release it after generating
2132 jit, to reduce a bit memory usage, and also to make it
2133 easier to understand what data is available during
2134 jit runtime.
2135
21362013-03-06 Paulo Andrade <pcpa@gnu.org>
2137
2138 * lib/lightning.c: Make data and code buffer readonly.
2139
21402013-02-20 Paulo Andrade <pcpa@gnu.org>
2141
2142 * doc/body.texi: Fool proof validate the examples of what
2143 an assembly-language programmer would write and correct the
2144 wrong sparc example.
2145
21462013-02-19 Paulo Andrade <pcpa@gnu.org>
2147
2148 * doc/body.texi: Add back the SPARC code generation example.
2149
21502013-02-19 Paulo Andrade <pcpa@gnu.org>
2151
2152 * check/lightning.c: Remove state flag to work with partial
2153 sparc port, by just disassembling if there was incomplete
2154 code generation.
2155
2156 * jit_sparc-cpu.c: Correct wrong range check for immediate
2157 integer constants (off by one bit shift).
2158 Correct macro implementing equivalent "rd %y, rd" assembly.
2159 Implement qmul* and qdiv*.
2160
2161 * jit_sparc.c: Update for qmul* and qdiv* and remove logic
2162 to handle incomplete code generation during sparc port.
2163
21642013-02-18 Paulo Andrade <pcpa@gnu.org>
2165
2166 * check/float.tst: Add sparc to list of known NaN and +-Inf
2167 to integer conversion.
2168
2169 * check/lightning.c: Define __sparc__ to preprocessor in
2170 the sparc backend.
2171
2172 * include/lightning/jit_private.h: Correct wrong definition
2173 of emit_stxi_d, that has lived for a long time, but would
2174 cause problems whenever needing to spill/reload a float
2175 register.
2176
2177 * include/lightning/jit_sparc.h: Can only use %g2,%g3,%g4
2178 for scratch variables, as other "global" registers are
2179 reserved for the system, e.g. libc.
2180 Reorder float register naming to make it easier to
2181 access odd float registers, so that generating code for
2182 pusharg and getarg is easier for the IR.
2183
2184 * lib/jit_mips-cpu.c, lib/jit_ppc-cpu.c: Update to match
2185 new code in jit_sparc-cpu.c. It must call jit_get_reg
2186 with jit_class_nospill if using the register to move
2187 an unconditional branch address to it, as the reload
2188 will not happen (actually could happen in the delay
2189 slot...)
2190
2191 * lib/jit_sparc-cpu.c: Correct wrong macro definition for
2192 ldxr_s.
2193 Properly implement div* and implement rem. Div* needs
2194 to use the y register, and rem* needs to be synthesized.
2195 Correct b?sub* macro definitions.
2196
2197 * lib/jit_sparc-fpu.c: Correct reversed float to/from double
2198 conversion.
2199 Correct wrong jit_get_reg call asking for a gpr and then
2200 using the fpr with that number.
2201 Correct wrong branch displacement computation for
2202 conditional branches.
2203
2204 * lib/jit_sparc.c: Correct getarg_d and pushargi_d implementation.
2205 Add rem* entries to the switch converting IR to machine code.
2206
2207 * lib/lightning.c: Correct a problem detected when adding
2208 the jit_class_nospill flag to jit_get_reg, that was caused
2209 when having a branch to an "epilog" node, what would cause
2210 the code to think all registers in unknown state were live,
2211 while in truth, all registers in unknown state in the
2212 "just after return" point are actually dead.
2213
22142013-02-17 Paulo Andrade <pcpa@gnu.org>
2215
2216 * include/lightning/jit_sparc.h, lib/jit_sparc-cpu.c,
2217 lib/jit_sparc-fpu.c, lib/jit_sparc.c: New files implementing
2218 the basic framework of the sparc port.
2219
2220 * configure.ac, include/lightning.h, include/lightning/Makefile.am,
2221 include/lightning/jit_private.h, lib/jit_disasm.c: Update
2222 for the sparc port framework.
2223
2224 * lib/jit_mips.c: Correct reversed retr/reti logic.
2225
2226 * lib/jit_ppc.c: Correct misspelled __LITTLE_ENDIAN.
2227
2228 * lib/lightning.c: Always do byte hashing in hash_data, because
2229 the logic to "compress" strings causes large pointers to not
2230 be guaranteed aligned at 4 byte boundaries.
2231 Update for the sparc port framework.
2232
22332013-02-11 Paulo Andrade <pcpa@gnu.org>
2234
2235 * lib/jit_arm.c: Correct jit_pushargi_f in the arm hardfp abi.
2236 Most of the logic uses even numbered register numbers, so that
2237 a float and a double can be used in the same register, but
2238 the abi requires packing the float arguments, so jit_pushargi_f
2239 needs to allocate a temporary register to modify only the
2240 proper register argument (or be very smart to push two
2241 immediate arguments if applicable).
2242
22432013-02-11 Paulo Andrade <pcpa@gnu.org>
2244
2245 * include/lightning.h, lib/lightning.c: Implement the new
2246 jit_clear_state and jit_destroy_state calls. jit_clear_state
2247 releases all memory not required during jit_execution; that
2248 is, leaves only the mmap'ed data and code buffers allocated.
2249 jit_destroy_state releases the mmap'ed buffers as well as
2250 the jit_state_t object itself, that holds pointers to the
2251 code and data buffers, as well as annotation pointers (for
2252 disassembly or backtrace) in the data buffer.
2253
2254 * lib/jit_note.c: Correct invalid vector offset access.
2255
2256 * check/ccall.c, check/lightning.c, doc/ifib.c, doc/incr.c,
2257 doc/printf.c, doc/rfib.c, doc/rpn.c: Use the new jit_clear_state
2258 and jit_destroy_state calls, to demonstrate the new code to
2259 release all jit memory.
2260
2261 * doc/body.texi: Add basic documentation and usage description
2262 of jit_clear_state and jit_destroy_state.
2263
22642013-02-11 Paulo Andrade <pcpa@gnu.org>
2265
2266 * include/lightning/jit_private.h, lib/jit_note.c, lib/lightning.c:
2267 Store all annotation information in the mmap'ed area reserved for
2268 read only data. This adds code to not allocate memory for jit_note_t
2269 objects, and to relocate jit_line_t objects and its contents after
2270 calculating annotation information. The jit_line_t objects are
2271 relocated because it is not possible to always calculate before
2272 hand data layout because note information may be extended or
2273 redundant entries removed, as well as allowed to be added in
2274 non sequential order.
2275 A bug was also corrected in _jit_set_note, that was causing it
2276 to allocate new jit_line_t objects when not needed. It was still
2277 working correctly, but allocating way more memory than required.
2278
22792013-02-05 Paulo Andrade <pcpa@gnu.org>
2280
2281 *include/lightning.h, lib/lightning.c: Add the new jit_live code
2282 to explicitly mark a register as live. It is required to avoid
2283 assuming functions always return a value in the gpr and fpr return
2284 register, and to avoid the need of some very specialized codes
2285 that vary too much from backend to backend, to instruct the
2286 optimization code the return register is live.
2287
2288 * lib/jit_arm.c, lib/jit_mips.c, lib/jit_ppc.c, lib/jit_print.c,
2289 lib/jit_x86.c: Update for the new jit_live code.
2290
2291 * check/ret.ok, check/ret.tst: New files implementing a simple
2292 test case that would previously fail at least in ix86/x86_64.
2293
2294 * check/Makefile.am: Update for new "ret" test case.
2295
22962013-02-05 Paulo Andrade <pcpa@gnu.org>
2297
2298 * lib/jit_ppc-cpu.c, lib/jit_ppc.c: Validate and correct
2299 problems in the qmul and qdiv ppc implementation.
2300
23012013-02-04 Paulo Andrade <pcpa@gnu.org>
2302
2303 * include/lightning.h, include/lightning/jit_private.h,
2304 lib/jit_arm-cpu.c, lib/jit_arm.c, lib/jit_mips-cpu.c,
2305 lib/jit_mips.c, lib/jit_ppc-cpu.c, lib/jit_ppc.c,
2306 lib/jit_x86-cpu.c, lib/jit_x86.c, lib/lightning.c:
2307 Implement the new qmul and qdiv instructions that return signed
2308 and unsigned lo/hi multiplication result and div/rem division result.
2309 These should be useful for jit translation of code that needs to
2310 know if a multiplication overflows (no branch opcode added) or if
2311 a division is exact (easy check if remainder is zero).
2312
2313 * check/lightning.c, lib/jit_print.c, check/Makefile.am,
2314 check/all.tst: Update for the new qmul and qdiv instructions.
2315
2316 * check/qalu.inc, check/qalu_div.ok, check/qalu_div.tst,
2317 check/qalu_mul.ok, check/qalu_mul.tst: New files implementing
2318 simple test cases for qmul and qdiv.
2319
23202013-01-30 Paulo Andrade <pcpa@gnu.org>
2321
2322 * doc/body.texi: Correct "jmpi" description that incorrectly
2323 told it was possible to pass any address as jump target. The
2324 only way to do that is "movi+jmpr".
2325
23262013-01-30 Paulo Andrade <pcpa@gnu.org>
2327
2328 * lib/jit_x86-cpu.c: Correct undefined behavior code.
2329 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56143
2330
23312013-01-29 Paulo Andrade <pcpa@gnu.org>
2332
2333 * configure.ac: Use AC_CONFIG_HEADERS instead of AC_CONFIG_HEADER
2334 to have HAVE_CONFIG_H defined with latest aclocal.
2335
2336 * include/lightning/jit_private.h, lib/lightning.c: Add new
2337 abstraction to use an heuristic to calculate amount of space
2338 required for jit generation, and code to reallocate buffer if
2339 did miscalculate it.
2340
2341 * lib/jit_arm.c, lib/jit_mips.c, lib/jit_ppc.c, lib/jit_x86.c:
2342 Update to use new code to estimate and resize of required buffer
2343 for jit code.
2344
2345 * lib/jit_x86-cpu.c: Minor cosmetic change to avoid adding a
2346 non required rex prefix when calling a function pointer stored
2347 in a register.
2348
23492013-01-24 Paulo Andrade <pcpa@gnu.org>
2350
2351 * check/Makefile.am: "make debug" target should pass only
2352 the main test tool program as argument for running gdb
2353
2354 * configure.ac: Add the --enable-assertions options.
2355
2356 * doc/Makefile.am, doc/body.texi, doc/lightning.texi:
2357 Major rewrite of the documentation to match the current
2358 implementation.
2359
2360 * doc/version.texi: Automatic date update.
2361
2362 * doc/ifib.c, doc/incr.c, doc/printf.c, doc/rfib.c, doc/rpn.c:
2363 Implementation of the documentation examples, that are also
2364 compiled during a normal build.
2365
2366 * doc/p-lightning.texi, doc/porting.texi, doc/toc.texi,
2367 doc/u-lightning.texi, doc/using.texi: These files were
2368 renamed in the documentation rewrite, as the documentation
2369 was significantly trimmed due to full removal of the porting
2370 chapters. Better porting documentation should be added but
2371 for the moment it was just removed the documentation not
2372 matching the implementation.
2373
23742013-01-18 Paulo Andrade <pcpa@gnu.org>
2375
2376 * lib/jit_note.c: Correct bounds check and wrong code keeping
2377 a pointer that could be changed after a realloc call.
2378
23792013-01-18 Paulo Andrade <pcpa@gnu.org>
2380
2381 * check/3to2.tst, check/add.tst, check/allocai.tst, check/bp.tst,

2383 check/fib.tst, check/ldsti.tst, check/ldstr-c.tst, check/ldstr.tst,

2388 lib/jit_mips.c, lib/jit_note.c, lib/jit_ppc.c, lib/jit_print.c,
2389 lib/jit_x86.c, lib/lightning.c: Extend the "jit_note" abstraction
2390 with the new "jit_name" call, that receives a string argument, and
2391 should usually be called to mark boundaries of functions of code
2392 generating jit (that is, it is not expected that the language
2393 generating jit map its functions to jit functions).
2394
23952013-01-17 Paulo Andrade <pcpa@gnu.org>
2396
2397 * check/add.tst, check/allocai.tst, check/bp.tst, check/divi.tst,
2398 check/fib.tst, check/lightning.c, include/lightning/jit_arm.h,
2399 include/lightning/jit_mips.h, include/lightning/jit_ppc.h,
2400 include/lightning/jit_private.h, include/lightning/jit_x86.h:
2401 Make JIT_RET, JIT_FRET and JIT_SP private. These should not be
2402 used in any operations due to frequently having special
2403 constraints (usually JIT_FRET). JIT_FP must be made available
2404 because it must be used as the base register to access stack
2405 space allocated with jit_allocai.
2406
24072013-01-14 Paulo Andrade <pcpa@gnu.org>
2408
2409 * include/lightning.h, lib/lightning.c: Add an extra align
2410 argument to the jit_data call (that should be made private),
2411 so that it should not align strings at 8 bytes.
2412 Correct the jit_note call to include the null ending byte
2413 when adding label/note names to the "jit data section".
2414
24152013-01-11 Paulo Andrade <pcpa@gnu.org>
2416
2417 * lib/jit_note.c: New file implementing a simple string+integer
2418 annotation, that should be used to map filename and line number
2419 to offsets in the generated jit.
2420
2421 * include/lightning.h, lib/lightning.c: Update for the new
2422 note code.
2423 Add an extra mandatory argument to init_jit, that is used
2424 as argument to bfd_openr.
2425 Change from generic void* to char* the argument to jit_note
2426 and add an extra integer argument, to map to filename and
2427 line number.
2428
2429 * check/ccall.c, check/lightning.c, include/lightning/jit_private.h,
2430 lib/jit_arm.c, lib/jit_disasm.c, lib/jit_mips.c, lib/jit_ppc.c,
2431 lib/jit_print.c, lib/jit_x86.c: lib/Makefile.am: Update for the
2432 new annotation code.
2433
2434 * configure.ac, check/Makefile.am: Update to work with latest
2435 automake.
2436
24372013-01-09 Paulo Andrade <pcpa@gnu.org>
2438
2439 * include/lightning.h, lib/jit_arm.c, jit_mips-fpu.c,
2440 lib/jit_mips.c, lib/jit_print.c, lib/jit_x86.c, lib/lightning.c:
2441 Remove the jit_code_getarg_{f,d} and jit_code_pusharg{i,r}_{f,d}
2442 calls, replacing them with the new, internal only, jit_movr_w_f,
2443 jit_mov{r,i}_f_w, jit_movr_ww_d, and jit_mov{i,r}_d_ww, that
2444 better describe the operation being done, and allow removing
2445 the hackish code to detect special conditions for arm when
2446 moving from/to vfp from/to a grp register pair.
2447 Rename jit_code_retval_{f,d} to jit_code_x86_retval_{f,d} as
2448 it is specific to 32 bit x86, and used to move abi return
2449 value in x87 register to a sse register.
2450
24512013-01-05 Paulo Andrade <pcpa@gnu.org>
2452
2453 * check/cccall.c, check/ccall.ok: New test case to validate
2454 interleaved calls from/to C code and jit.
2455
2456 * check/Makefile.am: Update for the new ccall test case.
2457
2458 * include/lightning.h, lib/lightning.c: Add the new jit_address
2459 call that returns the real/final address of a "note" in the
2460 generated jit. It requires a jit_node_t as returned by the
2461 jit_note call, and is only valid after calling jit_emit.
2462 Add an intermediate solution to properly handle arm
2463 soft and softfp modes that move a double to an integer register
2464 pair. Currently it just adds extra tests for the condition,
2465 but the proper solution should be to have extra lightning
2466 codes for these conditions, codes which should be only used
2467 by the backends that need it, and merged with the existing
2468 jit_pusharg*_{f,d}.
2469
2470 * include/lightning/jit_private.h: Add new jit_state_t flag
2471 to know it finished jit_emit, so that calls to jit_address
2472 are valid.
2473
2474 * lib/jit_mips.c: Correct abi implementation so that the
2475 new ccall test case pass. Major problem was using
2476 _jit->function.self.arg{i,f} as boolean values, but that
2477 would cause lightning.c:patch_registers() to incorrectly
2478 assume only one register was used as argument when calling
2479 jit_regarg_p(); _jit->function.self.arg{i,f} must be the
2480 number of registers used as arguments (in all backends).
2481
2482 * lib/jit_x86.c: Add workaround, by marking %rax as used,
2483 to a special condition, when running out of registers and the
2484 allocator trying to spill and reload %rax, but %rax was used
2485 as a pointer to a function, what would cause the reload to
2486 destroy the return value. This condition can be better
2487 generalized, but the current solution is good enough.
2488
2489 * include/lightning/jit_ppc.h, lib/jit_ppc-cpu.c, lib/jit_ppc.c:
2490 Rewrite logic to handle arguments, as the original code was
2491 written based on a SysV pdf about the generic powerpc ABI,
2492 what did "invent" a new abi for the previous test cases, but
2493 failed in the new ccall test in Darwin PPC. Now it properly
2494 handles 13 float registers for arguments, as well as proper
2495 computation of stack offsets when running out of registers
2496 for arguments.
2497
24982013-01-02 Paulo Andrade <pcpa@gnu.org>
2499
2500 * check/float.tst: Correct test case to match ppc also
2501 converting positive infinity to 0x7fffffff.
2502
2503 * lib/jit_arm-swf.c: Correct typos with double underscores.
2504
2505 * lib/lightning.c: Correct remaining wrong reverse jump logic.
2506
25072012-12-29 Paulo Andrade <pcpa@gnu.org>
2508
2509 * lib/lightning.c: Correct both, wrong and confusing logic
2510 to compute the reverse of a jump. Now it properly matches
2511 C semantics for "eq" (==) and "ne" (!=) and correct computation
2512 of reverse of "uneq" as "gt".
2513
2514 * check/branch.tst: Update "ne" float branch check that
2515 previously happened to be wrongly tested with a NaN argument.
2516
25172012-12-29 Paulo Andrade <pcpa@gnu.org>
2518
2519 * check/float.ok, check/float.tst: New test cases implementing
2520 extensive validation of float comparison and branch code
2521 generation as well as integer conversion, involving NaN and
2522 [+-]Inf.
2523
2524 * lib/jit_arm-swf.c, lib/jit_x86-sse.c, lib/jit_x86-x87.c:
2525 Correct bugs found by new float test case.
2526
2527 * lib/jit_x86.c: Correct cut&paste error added in commit to
2528 convert jit_arg* return value to a jit_node_t*, that would
2529 cause it to not properly handle double arguments in ix86.
2530
2531 * check/Makefile.am: Update for the new test case.
2532
25332012-12-28 Paulo Andrade <pcpa@gnu.org>
2534
2535 * check/lightning.c, include/lightning.h, lib/jit_arm.c,
2536 lib/jit_mips.c, lib/jit_ppc.c, lib/jit_print.c, lib/jit_x86.c,
2537 lib/lightning.c: Change return value of jit_arg{,_f,_d} to
2538 a jit_node_t* object, that should be used as argument to
2539 jit_getarg_{c,uc,s,us,i,ui,l,f,d}. This just requires changing
2540 from jit_int32_t to jit_pointer_t (or jit_node_t*) the "handle"
2541 for the getarg calls, with the benefit that it makes it easy
2542 to implement patching of the stack address of non register
2543 arguments, this way allowing to implement variable size stack
2544 frames if applicable; useful if there are too many registers and
2545 jit functions uses only a few callee save registers.
2546
25472012-12-27 Paulo Andrade <pcpa@gnu.org>
2548
2549 * lib/jit_arm.c, lib/jit_mips-cpu.c, lib/jit_mips.c: Correct
2550 regressions when patching jit_calli for a forward function.
2551
2552 * lib/jit_ppc-cpu.c: Correct wrong arguments to ANDI opcode
2553 in jit_getarg_u{c,s} implementation.
2554
25552012-12-23 Paulo Andrade <pcpa@gnu.org>
2556
2557 * check/call.ok, check/call.tst: New test cases to validate
2558 simple typed argument and return values in function calls.
2559
2560 * check/lightning.c: Properly handle jit_movi of labels for
2561 backward and forward code labels.
2562
2563 * check/Makefile.am: Update for new test case.
2564
25652012-12-23 Paulo Andrade <pcpa@gnu.org>
2566
2567 * check/carry.ok, check/carry.tst: New test case to validate
2568 carry condition handling.
2569
2570 * check/Makefile.am: Update for new test case.
2571
25722012-12-22 Paulo Andrade <pcpa@gnu.org>
2573
2574 * lib/jit_ppc-cpu.c, lib/jit_ppc.c: Implement logic for
2575 jit_htonr for big endian, so that ppc (big endian) pass the
2576 new clobber.tst test case.
2577
25782012-12-22 Paulo Andrade <pcpa@gnu.org>
2579
2580 * lib/jit_arm.c: Correct use of wrong argument offset
2581 variable in armv7l or float/double argument for varargs
2582 function in armv7hl.
2583 Correct jit_getarg* logic in software float mode to
2584 match expected behavior in other backends, that is, if
2585 a function is not called, it is safe to use a few lightning
2586 calls before a next jit_getarg* call, as done in the test
2587 case check/stack.tst. The proper solution should be to
2588 extend the parser in lib/lightning.c to check if there is
2589 some float operation that will call some (libgcc?) function,
2590 but software float arm should be a very uncommon backend for
2591 lightning, so, just load the already in place arguments
2592 saved to stack, assuming the register argument was clobbered
2593 (what should not be the case most times...).
2594
25952012-12-22 Paulo Andrade <pcpa@gnu.org>
2596
2597 * check/clobber.ok, check/clobber.tst: New test case doing
2598 extensive validation tests to ensure registers not used in
2599 a operation are not clobbered.
2600
2601 * check/Makefile.am: Update for new test case.
2602
26032012-12-21 Paulo Andrade <pcpa@gnu.org>
2604
2605 * lib/lightning.c: Partially rewrite/revert code to compute
2606 initial register live state at the start of a basic block.
2607 The original logic was corrupted when adding optimizations
2608 to do as few computations as possible in jit_update. The
2609 reglive field must be always a known set of live registers
2610 at the start of a basic block. The value that was incorrect
2611 was the regmask field, that must be the set of registers
2612 that are in unknown state, because they are not known live,
2613 neither set (or possibly not set) in the basic block, and
2614 *must* store the state at the start of the basic block.
2615
26162012-12-20 Paulo Andrade <pcpa@gnu.org>
2617
2618 * include/lightning/jit_ppc.h: Correct mismatch of JIT_F{1,5}
2619 with enum codes, that were correct, and returned by jit_f().
2620
2621 * lib/jit_ppc-cpu.c, lib/jit_ppc-fpu.c, lib/jit_ppc.c: Properly
2622 implement and better describe values when generating stack
2623 frames.
2624
26252012-12-18 Paulo Andrade <pcpa@gnu.org>
2626
2627 * check/stack.ok, check/stack.tst: New files to test data
2628 integrity on a deep chain of stack frames.
2629
2630 * lib/jit_arm.c, lib/jit_arm-cpu.c, lib/jit_mips.c,
2631 lib/jit_mips-cpu.c, lib/jit_ppc.c, lib/jit_ppc-cpu.c,
2632 lib/jit_x86.c, lib/jit_x86-cpu.c: Calculate _jit->function->stack
2633 in the emit stage, otherwise it will calculate it wrong if
2634 need to jit_allocai space to spill registers.
2635
2636 * lib/lightning.c: Correct wrong offset when updating the
2637 "current" jit function pointer in the code that may need to
2638 allocate stack space to spill registers.
2639
2640 * check/lightning.c: Correct off by one data space check.
2641
2642 * check/Makefile.am: Update for new test case.
2643
26442012-12-17 Paulo Andrade <pcpa@gnu.org>
2645
2646 * check/fop_abs.ok, check/fop_abs.tst, check/fop_sqrt.ok,
2647 check/fop_sqrt.tst: New files implementing simple test cases
2648 for the extra float operations.
2649
2650 * check/Makefile.am: Update for new test cases.
2651
2652 * check/alu.inc: Add an extra macro to check for unordered
2653 equality on tests where it is expected to use NaN as an
2654 argument.
2655
2656 * check/lightning.c: Minor change for proper/common argument
2657 syntax handling ommiting arguments to options.
2658
26592012-12-17 Paulo Andrade <pcpa@gnu.org>
2660
2661 * check/Makefile.am: Automatically generate pattern list
2662 of tests with alternate jit generation options. This should
2663 prevent typos and needing to change multiple places after
2664 a change.
2665
26662012-12-14 Paulo Andrade <pcpa@gnu.org>
2667
2668 * check/lightning.c: Remove the ".cpu name value" syntax,
2669 as it was not able to do proper changes before the jit
2670 internal data structure was initialized. Now it supports
2671 several getopt options to force using different jit
2672 generation options, effectively replacing the previous
2673 syntax.
2674
2675 * check/run-test: Add simple extra logic to handle differently
2676 named test scripts, used to test things like x87 coprocessor
2677 in ix86, and arm instruction set or software float in armv7l.
2678
2679 * configure.ac: Add some AC_RUN_IFELSE calls to figure at
2680 compile time if can test different code generation options,
2681 and update Makefile generation accordingly.
2682
2683 * check/Makefile.am, lib/jit_arm.c, lib/jit_x86.c: Update to
2684 properly work with the test tool updating the jit_cpu global
2685 information.
2686
2687 * check/check.arm.sh, check/check.swf.sh, check/check.x87.sh:
2688 New wrapper files passing -mthumb=0, mvfp=0 and -mx87=1 to
2689 the test tool, if applicable, so that it can validate alternate
2690 code generation options on test hosts that support them.
2691
26922012-12-14 Paulo Andrade <pcpa@gnu.org>
2693
2694 * lib/jit_x86-x87.c, lib/jit_x86.c: Correct test cases in ix86
2695 when using the x87 coprocessor instead of sse2+.
2696
26972012-12-14 Paulo Andrade <pcpa@gnu.org>
2698
2699 * include/lightning.h, include/lightning/jit_private.h,
2700 lib/jit_arm.c, lib/jit_mips.c, lib/jit_ppc.c, lib/jit_x86.c,
2701 lib/lightning.c: Make jit_ellipsis implementation not
2702 backend specific. It is not intended to handle va_list
2703 like objects at runtime, as jit_arg* and jit_getarg*
2704 return constant values resolved at parse time, so, effectively
2705 it is not possible to create printf like jit functions, as
2706 there is no va_start, va_arg, va_end, etc, abstraction. This
2707 limitation should be kept for the sake of making new ports
2708 easier.
2709
27102012-12-14 Paulo Andrade <pcpa@gnu.org>
2711
2712 * include/lightning.h, lib/lightning.c: Add two extra wrapper
2713 functions to avoid need for excess pointer to/from word casts.
2714
2715 * check/lightning.c: Only need for pointer to/from word cast
2716 now is jit_movi, update accordingly.
2717
27182012-12-13 Paulo Andrade <pcpa@gnu.org>
2719
2720 * check/varargs.ok, check/varargs.tst: New test cases implementing
2721 simple varargs calls with a large amount of arguments to exercise
2722 excess arguments on stack.
2723
2724 * include/lightning.h: Include config.h if HAVE_CONFIG_H is
2725 defined.
2726
2727 * lib/jit_arm.c: Allocate a fpr register, not a gpr one for
2728 temporary when pushing varargs arguments in the stack.
2729
2730 * lib/jit_arm-swf.c: Correct code changing the wrong offset
2731 in jit_absr_d and jit_negr_d in software float.
2732
2733 * lib/jit_mips.c: Correct calculation of offsets of arguments
2734 on stack.
2735
2736 * lib/jit_ppc.c: Correct bogus logic for "next" offset of arguments
2737 on stack and adjust for fixed offset of stack arguments.
2738
27392012-12-12 Paulo Andrade <pcpa@gnu.org>
2740
2741 * include/lightning.h, lib/jit_arm.c, lib/jit_mips.c,
2742 lib/jit_ppc.c, lib/jit_x86.c, lib/lightning.c: Change jit_prepare
2743 to no longer receive an argument. If receiving an argument, it
2744 should be an ABI specifier, not a boolean if varargs or not,
2745 and add the new jit_ellipsis call, to specify where the
2746 ellipsis is in the C prototype of the function being called.
2747 Note that currently it is not supported to define varargs
2748 functions and it will be ignored if calling jit_ellipsis not
2749 in a prepare/finish* block, but this should be addressed.
2750
2751 * check/allocai.tst, check/alu_add.tst, check/alu_and.tst,
2752 check/alu_com.tst, check/alu_div.tst, check/alu_lsh.tst,
2753 check/alu_mul.tst, check/alu_neg.tst, check/alu_or.tst,

2759 check/ldstxr-c.tst, check/ldstxr.tst, check/rpn.tst,
2760 check/lightning.c: Update for the change to jit_prepare and
2761 addition of jit_ellipsis.
2762
27632012-12-11 Paulo Andrade <pcpa@gnu.org>
2764
2765 * lib/jit_ppc-cpu.c: Make movr a function that checks arguments
2766 so that other code can safely assume it is a noop if src and dst
2767 are the same register.
2768 Implement rem{r,i}{,_u} as a div{,u}/mul/sub.
2769 Correct ANDIS, ORIS and XORIS calls to cast the argument to
2770 unsigned before the shift to avoid an assertion if the argument
2771 had the topmost bit set.
2772 Implement lshi, rshi and rshi_u as functions to test for a
2773 zero argument, that would otherwise trigger an assertion when
2774 computing the shift value.
2775 Do a simple implementation of bm{s,c}{r,i} with a temporary,
2776 "andr" of arguments and jump based on comparison with zero.
2777 Correct typo in ldxi_c.
2778
2779 * lib/jit_ppc-fpu.c: Correct wrong arguments to FDIV* and STF*.
2780
2781 * lib/jit_ppc.c: Correct wrong check for 6 instead of 8 integer
2782 arguments in registers. If calling a varargs function and
2783 passing a float or double argument, also either store the
2784 value in the stack or in integer registers, as varargs functions
2785 do not fetch it from float registers.
2786 Add "case" for new functions and incorrectly missing ones.
2787 Call libgcc's __clear_cache, that should know what to do
2788 if the hardware needs flushing cache before execution.
2789
2790 * lib/lightning.c: Do a simple/trivial logic in jit_regset_scan1,
2791 that should make it easier for the compiler to optimize it, and
2792 that also corrects the previously wrong code for big endian, and
2793 that was causing problems in ppc due to not saving all callee save
2794 registers as it was not "finding" them in the regset due to the
2795 little endian assumption bug.
2796
27972012-12-11 Paulo Andrade <pcpa@gnu.org>
2798
2799 * configure.ac: Only default to using the builtin disassembler
2800 if on GNU/Linux. This should be temporary, due to requiring
2801 /proc/self/exe.
2802 Correctly check $target_cpu for powerpc.
2803
2804 * include/lightning/jit_ppc.h: Correctly implement jit_v_num.
2805
2806 * include/lightning/jit_private.h: Declare proper prototype
2807 for jit_init_debug and jit_finish_debug.
2808
2809 * lib/jit_ppc-cpu.c: Remove code to save/restore callee save
2810 float registers, as it is not required since those float
2811 registers are not usable currently.
2812 Change prolog and epilog generation to, at least comparing
2813 code, match what gcc generates in "gcc -O0", but it is still
2814 failing in Darwin PPC, apparently due to the __clear_cache
2815 call not being enough, as frequently it will also fail to
2816 execute, and the code buffer is all zeroes.
2817
2818 * lib/lightning.c: Do not fail in jit_regset_scan1 calls due
2819 to passing 64 as argument on computers with 64 registers.
2820
28212012-12-10 Paulo Andrade <pcpa@gnu.org>
2822
2823 * lib/jit_mips-cpu.c: Correct all current test cases.
2824 Call the "xori" not the "XORI" macro for jit_xori implementation,
2825 as the XORI macro handles only 16 bit unsigned values.
2826 Call the "movr" macro, not the "movi" macro in the special
2827 case of adding or subtracting zero.
2828 Use the proper temporary register in the jit_andr implementation.
2829
28302012-12-09 Paulo Andrade <pcpa@gnu.org>
2831
2832 * check/alu.inc, check/alu_add.ok, check/alu_add.tst,
2833 check/alu_and.ok, check/alu_and.tst, check/alu_com.ok,
2834 check/alu_com.tst, check/alu_div.ok, check/alu_div.tst,
2835 check/alu_lsh.ok, check/alu_lsh.tst, check/alu_mul.ok,
2836 check/alu_mul.tst, check/alu_neg.ok, check/alu_neg.tst,
2837 check/alu_or.ok, check/alu_or.tst, check/alu_rem.ok,
2838 check/alu_rem.tst, check/alu_rsh.ok, check/alu_rsh.tst,
2839 check/alu_sub.ok, check/alu_sub.tst, check/alu_xor.ok,
2840 check/alu_xor.tst, check/alux_add.ok, check/alux_add.tst,
2841 check/alux_sub.ok, check/alux_sub.tst, check/branch.ok,
2842 check/branch.tst: New test cases for arithmetic and branch
2843 tests.
2844
2845 * check/Makefile.am: Update for new test cases.
2846
2847 * include/lightning/jit_private.h: Make the jit_reg_free_p
2848 macro shared by all backends. Previously was added for the
2849 arm backend, but is useful in the x86_64 backend when checking
2850 state of "special purpose register".
2851 Also add the new jit_class_named register class, that must be
2852 or'ed with the register value if calling jit_get_reg expecting
2853 an specific value, because the specific register value may be
2854 zero, that previously was treated as no register requested.
2855
2856 * lib/jit_arm-cpu.c: Correct argument order for T2_MVN.
2857
2858 * lib/jit_arm-swf.c: Call the proper function for double
2859 divide. The "software float" implementation just calls
2860 libgcc functions.
2861
2862 * lib/jit_arm.c: Return float/double values in the float
2863 register if using the hard float ABI.
2864
2865 * lib/jit_x86-cpu.c: Change the can_sign_extend_int_p macro
2866 to not include -0x80000000L, because there is code that
2867 "abuses" it and thinks it can negate the immediate value
2868 after calling that macro.
2869 Correct implementation of jit_subi that had a wrong code
2870 patch logic doing subtraction with reversed arguments.
2871 Correct REX prefix calculation in the jit_muli implementation.
2872 Correct logic to get/unget %*ax and %*dx registers in divremr
2873 and divremi.
2874 Correct divremi that was using the symbolic, unique %*ax
2875 value in on place (not using the _REGNO name suffix).
2876 Correct cut&paste error causing it to use "xor" instead of
2877 "or" in one code path of the jit_ori implementation.
2878 Correct several flaws when clobbering registers and/or when
2879 one of the arguments was %*cx in the rotshr wrapper function
2880 implementing most shift operations.
2881
2882 * lib/lightning.c: No longer expect that the backend be smart
2883 enough to know what to do when asking for a named register
2884 if that register is already an argument or is live. It fails
2885 if it is an argument, or if register is live, fails if cannot
2886 spill.
2887 No longer incorrectly assume that eqr_{f,d} and ltgr_{f,d} are
2888 safe to inverse value tests in jump thread optimization.
2889
28902012-12-05 Paulo Andrade <pcpa@gnu.org>
2891
2892 * check/Makefile.am, check/cvt.ok, check/cvt.tst: Add new
2893 "cvt" test case to test conversion from/to int/float types.
2894
2895 * check/lightning.c: Only define truncr_{f,d}_l in 64 bit mode.
2896
2897 * include/lightning.h: Correct typo that caused it to define
2898 jit_truncr_{f,d}_l in 32 bit mode.
2899
2900 * lib/jit_arm-cpu.c: Avoid assertion failure in the signed/unsigned
2901 extend opcodes generation as it shares an interface for 3 argument
2902 opcode generation.
2903
2904 * lib/jit_x86-cpu.c: Correct wrong argument passed to
2905 jit_unget_reg in the andi implementation and wrong byte
2906 unsigned extend code generation.
2907
2908 * lib/jit_x86-sse.c: Correct conversion from "word" to float or
2909 double as is dependent on wordsize.
2910
29112012-12-05 Paulo Andrade <pcpa@gnu.org>
2912
2913 * check/ldstr-c.ok, check/ldstr-c.tst, check/ldstxi-c.ok,
2914 check/ldstxi-c.tst, check/ldstxr-c.ok, check/ldstxr-c.tst:
2915 New test case files testing load clobbering the base and/or
2916 index register;
2917
2918 * check/ldst.inc: New file with common definition for all the
2919 ldst* test cases.
2920
2921 check/Makefile.am, check/ldsti.tst, check/ldstr.tst,
2922 check/ldstxi.tst, check/ldstxr.tst: Update for new common
2923 definitions file and new register clobber ldst tests.
2924
29252012-12-05 Paulo Andrade <pcpa@gnu.org>
2926
2927 * lib/jit_mips-fpu.c: Correct wrong register order in stxr_{f,d}
2928 in the mips backend.
2929
29302012-12-05 Paulo Andrade <pcpa@gnu.org>
2931
2932 * lib/jit_arm-vfp.c: Correct regression found in armv7l with
2933 latest test cases.
2934
29352012-12-05 Paulo Andrade <pcpa@gnu.org>
2936
2937 * check/ldstxi.tst, check/ldstxr.tst: Correct wrong argument
2938 order for 32 bit mode tests.
2939
2940 * configure.ac: Correct check for ix86 target_cpu.
2941
29422012-12-05 Paulo Andrade <pcpa@gnu.org>
2943
2944 * check/ldstr.ok, check/ldstr.tst, check/ldsti.ok,
2945 check/ldsti.tst, check/ldstxr.ok, check/ldstxr.tst,
2946 check/ldstxi.ok, check/ldstxi.tst:
2947 New test case files exercising a very large amount of
2948 register combinations to verify load/store implementation.
2949
2950 * check/Makefile.am: Update for new test cases.
2951
2952 * lib/jit_x86-cpu.c: Correct wrong argument order when
2953 computing REX prefix for {ld,st}r_T codes;
2954
29552012-12-04 Paulo Andrade <pcpa@gnu.org>
2956
2957 * lib/jit_mips-fpu.c, lib/jit_mips.c: Implement missing mips
2958 jit_sqrtr_{f,d} codes.
2959
2960 * check/all.tst, include/lightning.h, lib/jit_print.c: Change
2961 declaration order and call order in all.tst of {add,sub}c and
2962 {add,sub}x. *c must be called before to set the carry and *x
2963 second to use the carry and keep it set. The wrong call order
2964 was causing all.tst to fail in mips, where a register is
2965 allocated to keep a global carry state.
2966
29672012-12-04 Paulo Andrade <pcpa@gnu.org>
2968
2969 * include/lightning/jit_mips.h, lib/jit_mips-cpu.c,
2970 lib/jit_mips-fpu.c, lib/jit_mips.c: Correct float/double
2971 argument handling and make the mips backend pass the initial
2972 test cases.
2973
2974 * include/lightning.h, ib/jit_print.c, lib/lightning.c:
2975 Add extra enum values for argument handling functions that
2976 could not be abstracted to the current codes, that is, when
2977 float values need to move from/to gpr from/to fpr. It would
2978 be more tempting to add such primitives, but they would have
2979 wordsize limitations, and it is not expected to add codes
2980 with one gpr argument for 64 bit and two for 32 bit.
2981
2982 * lib/jit_ppc.c: Check _jit->function before calling jit_epilog()
2983 to avoid a runtime exception.
2984
29852012-12-04 Paulo Andrade <pcpa@gnu.org>
2986
2987 * include/lightning/jit_mips.h, lib/jit_mips.c: Update to
2988 make the mips backend compile in a qemu image.
2989
2990 * lib/jit_ppc.c: Minor adaptations to help in having the
2991 ppc backend compilable.
2992
29932012-12-03 Paulo Andrade <pcpa@gnu.org>
2994
2995 * configure.ac, include/lightning/jit_private.h, lib/jit_arm-cpu.c,
2996 lib/jit_arm-swf.c, lib/jit_arm.c, check/Makefile.am: Correct
2997 implementation of the arm backend port to build and pass the
2998 current test cases. Tested on armv7 with softfp abi.
2999
3000 * lib/jit_disasm.c: Rename and change prototype of static
3001 disassemble function as in the arm backend it is required
3002 to access state information stored in the jit_state_t object.
3003
3004 * check/3to2.tst, check/add.tst: Correct test case code assuming
3005 JIT_RO and JIT_RET are the same, and even if they are the same,
3006 the logic was incorrect because it must always call jit_retval*
3007 to fetch a function call return before any other instruction.
3008 The arm backend hash a special condition if jit_retval is not
3009 called, because "r0" is not JIT_R0, but is JIT_RET and *also*
3010 the first argument for a called function, so JIT_RET must be
3011 only used as an argument to jit_retval.
3012
30132012-12-03 Paulo Andrade <pcpa@gnu.org>
3014
3015 * check/all.tst, check/lightning.c: Only declare or use 64 bit
3016 interfaces on 64 bit builds.
3017
3018 * check/fib.tst: Use simpler logic to not need preprocessor
3019 conditionals for 32 or 64 bit.
3020
3021 * include/lightning.h: Only declare 64 bit macros on a 64 bit
3022 build. Code using lightning must know about wordsize and the
3023 jit generation limitations, also, this way it generates a
3024 compile time failure, not a runtime assertion.
3025
3026 * include/lightning/jit_x86.h: Correct typo in macro name.
3027
3028 * lib/jit_arm.c, lib/jit_arm-cpu.c, lib/jit_mips.c,
519a9ea1 3029 lib/jit_mips-cpu.c, lib/jit_ppc.c, lib/jit_ppc-cpu.c,
4a71579b
PC
3030 lib/jit_x86.c, lib/jit_x86-cpu.c: Correct wrong code to get
3031 current jit function pointer.
3032
3033 * lib/lightning.c: Move call to the simplify() optimization
3034 to after register liveness is known. Previous code did work
3035 by accident but now with proper test cases the problem was
3036 noticed.
3037
3038 * lib/jit_disasm.c: Always cast bfd_vma to long long when
3039 passing it as printf argument.
3040
30412012-12-03 Paulo Andrade <pcpa@gnu.org>
3042

3046
30472012-12-02 Paulo Andrade <pcpa@gnu.org>
3048
3049 * lib/jit_ppc.c: Assign copyright ownership to FSF.
3050
3051 * lib/jit_x86-cpu.c: Correct integer multiplication that was
3052 generating code with reversed register arguments.
3053
3054 * check/rpn.ok, check/rpn.tst: New test case file.
3055
30562012-12-02 Paulo Andrade <pcpa@gnu.org>
3057
3058 * lib/jit_x86-cpu.c, lib/jit_x86-sse.c, lib/jit_x86-x87.c:

3065 files implementing initial code different jit backends.
3066
3067 * include/lightning/jit_private.h: Add extra field to the
3068 private jit_patch_t type, required by the arm port.
3069
3070 * lib/Makefile.am: Update for the new backend implementation
3071 files.
3072
30732012-12-02 Paulo Andrade <pcpa@gnu.org>
3074
3075 * check/Makefile.am: Add proper "make clean" rule and missing

3077
30782012-12-02 Paulo Andrade <pcpa@gnu.org>
3079
3080 * .gitignore: Update pattern of ignored files.
3081
3082 * check/Makefile.am: Add rule to build liblightning.la dependency
3083 in case of running "make check" before building the library.

3100 and arm ports will be added. At first, sparc will not be
3101 supported as it has not yet been ported to the new engine.

3114 tests/rpnfp.ok, tests/sete.c, tests/sete.ok, tests/testfp.c,
3115 tests/testfp.ok, tests-run-test: Removed previous test suite, in
3116 favor of a newer one in the check subdirectory.
3117
3118 * check/3to2.ok, check/3to2.tst, check/add.ok, check/add.tst,
3119 check/allocai.ok, check/allocai.tst, check/bp.ok, check/bp.tst,
3120 check/divi.ok, check/divi.tst, check/fib.ok, check/fib.tst:
3121 New sample input for the new test program, loosely matching
3122 several of the previous test cases.
3123
3124 * check/Makefile.am: New test suite makefile.
3125
3126 * check/check.sh, check/run-test: New wrapper files for the
3127 new test suite.
3128
3129 * check/lightning.c: New file. The main driver of the new test
3130 suite, that compiles to a parser of a very simple assembly like
3131 language, generates jit and executes it.
3132
3133 * check/all.tst: New file. A generic debug and sample test file
3134 with a directive to prevent it from being executed, and useful to
3135 read disassembly of all possible instructions, using a fixed set
3136 of registers.
3137
3138 * include/Makefile.am, include/lightning.h,
3139 include/lightning/Makefile.am, include/lightning/jit_arm.h,
3140 include/lightning/jit_mips.h, include/lightning/jit_ppc.h,

3144 lib/jit_x86.c, lib/lightning.c: New files. These files are
3145 written from scratch, only by <pcpa@gnu.org>, and have now
3146 copyright assignment to the FSF. This is the core of the new
3147 lightning rework. Previously it was integrated in code with
3148 a garbage collector and several custom types like vectors and
3149 hash tables, so this first code merge with lightning converts
3150 that code into a library extracting only the jit bits, and at
3151 first only for x86_64 GNU/Linux.
3152
3153 * lightning.h, m4/lightning.m4: Removed. These are no longer
3154 required in the new lightning code.
3155
3156 .gitignore, Makefile.am, configure.ac: Update for the new
3157 lightning code.
3158
31592012-12-02 Paulo Andrade <pcpa@gnu.org>
3160 * .cvsignore: Removed for extra cleanup.
3161
3162 * build-aux: Rename directory to m4.
3163
3164 * m4: Renamed to "default" name and for consistency with merge
3165 with code rework to be imported in lightning.
3166
3167 * .gitignore, configure.ac, Makefile.am, doc/Makefile.am:
3168 Update for build-aux to m4 rename.
3169
31702012-12-01 Paulo Andrade <pcpa@gnu.org>
3171
3172 * opcode/Makefile.am, opcode/Makefile.in, opcode/ansidecl.h,

3174 opcode/i386-dis.c, opcode/i386.h, opcode/ppc-dis.c, opcode/ppc-opc.c,
3175 opcode/ppc.h, opcode/sparc-dis.c, opcode/sparc-opc.c, opcode/sparc.h,
3176 opcode/sysdep.h: Removed. Do not bundle GNU binutils files.
3177
3178 * aclocal.m4, configure, Makefile.in, config.h.in, doc/Makefile.in,
3179 lightning/Makefile.in, tests/Makefile.in: Removed. Do not maintain
3180 autogenerated files that also generate too much diff noise when
3181 regenerated in git.
3182
3183 * build-aux/help2man, build-aux/texinfo.tex, build-aux/texi2dvi:
3184 Removed. Buildenvironment must have an up to date version from
3185 upstream installed.
3186
3187 * build-aux/config.guess, build-aux/config.sub, build-aux/depcomp,
3188 build-aux/install-sh build-aux/mdate-sh build-aux/missing: Removed.
3189 Do not maintain a copy of automake files in git. Release tarballs
3190 must use an up to date version.
3191
3192 * lightningize.in, doc/lightningize.1: Removed. Do not encourage
3193 bundling lightning in other packages. It should use a system package
3194 or a proper thirdy part subdirectory.
3195
3196 * INSTALL: Removed. Autoreconf removes it and creates a symlink
3197 when regenerating files, so, avoid conflicts in git and let
3198 automake create the symlink.
3199
3200 * .gitignore: Add INSTALL and autogenerated files.
3201
3202 * configure.ac, Makefile.am: Update for removal of opcode subdir,
3203 auto generated files and lightningize.
3204
3205 * tests/Makefile.am, tests/3to2.c, tests/add.c, tests/bp.c,
3206 tests/fib.c, tests/fibdelay.c, tests/fibit.c, tests/funcfp.c,
3207 tests/incr.c, tests/printf.c, tests/rpn.c, tests/rpnfp.c,
3208 tests/sete.c, tests/testfp.c: Update for removal of opcode subdir.
3209
3210 * doc/Makefile.am: Update for removal of lightningize.
3211
3212 * configure.ac, lightning/ppc/funcs.h, lightning/sparc/funcs.h,
3213 lightning/i386/fp.h, lightning/i386/core.h, lightning/i386/asm.h,
3214 tests/3to2.c, tests/add.c, tests/bp.c, tests/fib.c, tests/fibdelay.c,
3215 tests/fibit.c, tests/funcfp.c, tests/incr.c, tests/printf.c,
3216 tests/rpn.c, tests/rpnfp.c, tests/sete.c, tests/testfp.c:
3217 Remove LIGHTNING_CROSS, it is half supported and incomplete.
3218
3219 * tests/3to2.c, tests/funcfp.c, tests/rpnfp.c: Remove preprocessor
3220 check on JIT_FPR. If no hardware registers are available, the backend
3221 must provide an alternative for software float.
3222
3223 * lightning/ppc/core.h, lightning/sparc/core.h, tests/Makefile.am:
3224 Remove JIT_NEED_PUSH_POP. It is absolutely not trivial to implement
3225 properly on some backends due to stack alignment constraints, and
3226 whenever it is required, using jit_allocai and using a properly
3227 aligned stack vector, or a heap buffer, is better.
3228
3229 * tests/push-pop.c, tests/push-pop.ok: Removed due to
3230 JIT_NEED_PUSH_POP no longer available.
3231
32322011-02-28 Paolo Bonzini <bonzini@gnu.org>

3341
3342 * lightning/ppc/funcs.h (jit_flush_code): modified the computation
3343 of start/end. The pointer arithmetic was done without casting. It
519a9ea1 3344 prevented compilation with recent gcc versions.
4a71579b
PC

3346 incorrect. Should have been 4 bytes below SP (not above).
519a9ea1
PC
3347 * lightning/ppc/core.h (jit_popr_i): The offset for the load was
3348 incorrect. Should have been 0 (not +8).

3364 the core.h has no effect on the 32-bit backend.
3365 * lightning/i386/core-64.h: Place JIT_R1/JIT_R2 in R10/R11,
3366 place outgoing arguments in the right spot from the beginning,
3367 define jit_save, fix jit_reg8/jit_reg16.
3368

3370
3371 * lightning/i386/core-64.h: Rewrite argument passing to
3372 support up to 6 arguments and generate less code.
3373
33742008-06-14 Laurent Michel <ldm@thorgal.homelinux.org>
