3 * include/lightning.h.in: Reorder jit_mov{n,z}r in instruction list.
4 * lib/jit_alpha.c, lib/jit_alpha-cpu.c, lib/jit_hppa.c,
5 lib/jit_hppa-cpu.c, lib/jit_ia64.c, lib/jit_ia64-cpu.c,
6 lib/jit_riscv.c, lib/jit_riscv-cpu.c, lib/jit_s390.c,
7 lib/jit_s390-cpu.c, lib/jit_sparc.c, lib/jit_sparc-cpu.c:
8 Implement fallback jit_mov{n,z}r. These are a somewhat cheap
9 implementation, but should be reviewed for the arches that already
10 have a proper conditional move.
11 * lib/jit_arm-sz.c, lib/jit_mips-sz.c: Add missing maximum size
12 estimative and reorder.
13 * lib/jit_aarch64-sz.c, lib/jit_x86-sz.c, lib/jit_ppc-sz.c:
14 Reorder entry to match definition order.
15 * lib/jit_aarch64-sz.c, lib/jit_alpha-sz.c, lib/jit_hppa-sz.c,
16 lib/jit_ia64-sz.c, lib/jit_riscv-sz.c, lib/jit_s390-sz.c,
17 lib/jit_sparc-sz.c: Add heuristic value, basically the sum of
18 the cost of a movr + beqr.
19 * lib/jit_names.c: Add entries for debug output of mov{n,z}r.
20 * lib/lightning.c: Use proper bitmask in jit_classify.

222021-04-03 Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de>
23
24 * check/Makefile.am: Add test for the live instruction.
25 * check/live.ok: New file.
26 * check/live.tst: New file.
27 * doc/body.texi: Add documentation for the live instruction and
28 for jit_get_reg/jit_get_unreg. Fix menu entries.
29 * include/lightning.h.in (jit_get_reg, jit_unget_reg): Expose the
30 macros in the public header file.
31 * include/lightning/jit_private.h (jit_get_reg, jit_unget_reg):
32 Remove the macros from the private header file.
33
342021-04-03 Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de>
35
36 * Makefile.am, check/Makefile.am, doc/Makefile.am,
37 lib/Makefile.am: Include $(top_builddir)/include in include paths
38 for the autoconf-generated header file lightning.h.
39
402021-04-03 Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de>
41
42 * doc/.gitignore: Add version.texi to list of ignored files.
43 * doc/version.texi: Remove file from version control.
44
452020-18-04 Paulo Andrade <pcpa@gnu.org>
46
47 * lib/jit_x86-cpu.c, lib/jit_x86.c: Implement %rip relative
48 calls and jumps on x86_64. Currently very conservative, assuming
49 a jit block can be larger than 2G, so, if a jump or call is in
50 the same jit generation, but target is unknown, use an indirect
51 branch (could have an option to assume a jit code block is
52 never larger than 2G). Also a deoptimization is that now does
53 not always generate ip relative jmpi; previously implicitly
54 assumed jmpi would never be larger than 2G. Overall still an
55 optimization.

572020-23-01 Paulo Andrade <pcpa@gnu.org>
58
59 * lib/lightning.c: Add a proper fix to the condition of considering
60 a register dead at entry of a block when it modifies the register
61 !after! a branch to a target where it is live.
62 The correction is just to split blocks on branches. It uses an
63 extra label per branch, but makes following the code simpler and
64 avoid costly searches.
65
662020-22-01 Paulo Andrade <pcpa@gnu.org>
67
68 * lib/lightning.c: Correct a special condition of a register
69 only assigned in a block, and incorrectly marked as dead before
70 a jump where the register is live.
71
722019-10-04 Paulo Andrade <pcpa@gnu.org>
73
74 * check/lightning.c, include/lightning/jit_private.h,
75 include/lightning/jit_x86.h, lib/jit_x86-cpu.c, lib/jit_x86-sz.c,
76 lib/jit_x86.c: Correct issues with MinGW64 that defines _WIN32
77 and needs long long for jit_word_t.
78
792019-09-16 Paulo Andrade <pcpa@gnu.org>
80
81 * lib/lightning.c: Do not add registers that are never modified
82 to the set of registers to scan for live range, what might
83 consume a lot of cpu time, doing nothing.
84
519a9ea1 852019-09-16 Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de>
4a71579b
PC
86
87 * include/lightning/jit_x86.h, lib/jit_x86.c: Correct x86_64
88 backend, made %r12 a callee-save register as dictated by the
89 System V AMD64 ABI.
90
912019-09-16 Paulo Andrade <pcpa@gnu.org>
92
93 * Makefile.am: Do not force CFLAGS for the get_jit_size target.
94 * check/lightning.c: Drop __ppc__ check.
95 * include/lightning.h.in: Drop __ppc__ check. Add new
96 jit_flag_vararg flag, for special case in powerpc 32 bit using
97 the SYSV abi, and need to pass an extra argument during code
98 generation.
99 * include/lightning/jit_ppc.c: Drop __ppc_ check. Remove the
100 ABI_ELFv2 macro, as it now directly checks for the _CALL_ELF
101 value when/if appropriate.
102 * include/lightning/jit_private.h: Drop __ppc_ check. Check for
103 _CALL_AIXDESC to define extra data to handle function
104 descriptors.
105 * lib/jit_ppc-cpu.c: Update to check for _CALL_SYSV; assume
106 !_CALL_SYSV == (_CALL_AIX || _CALL_LINUX). Significant code
107 rework for the SYSV abi.
108 * lib/jit_ppc-sz.c: Update for the SYSV abi.
109 * lib/jit_ppc.c: Update for the SYSV abi. Add matching va_list
110 type. Drop __ppc__ check.
111 * lib/jit_size.c: Drop __ppc_ check.
112 * lib/lightning.c: Drop __ppc__ check. Add proper check for
113 __powerpc__ and _CALL_AIXDESC to manage function descriptors.
114 * lib/size.c: Update to drop __pppc_ check and SYSV abi.
115
1162019-08-30 Paulo Andrade <pcpa@gnu.org>
117
118 * lib/jit_mips-cpu.c: Use JALR to get the same effect as JR, as
119 in mips32r6 JR generates an illegal instruction. Thanks to
120 Bruno Haible for providing a patch and the information, reported at
121 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=925129
122 * THANKS: update.

125
126 * include/lightning/jit_private.h: Move definition of offsetof
127 from the public header file here.
128
129 * configure.ac, include/Makefile.am, include/lightning.h,
130 include/lightning.h.in: Generate lightning.h from lightning.in.h
131 and remove the dependence on config.h from the public header file.
132
1332019-06-04 Paulo Andrade <pcpa@gnu.org>
134
135 * include/lightning/jit_riscv.h, lib/jit_riscv-cpu.c,
136 lib/jit_riscv-fpu.c, lib/jit_riscv-sz.c, lib/jit_riscv.c:
137 Implement riscv port. Only 64 bit Linux supported. Built on
138 Fedora 28 image.
139
140 * check/all.tst, check/float.tst, configure.ac, include/lightning.h,
141 include/lightning/Makefile.am, include/lightning/jit_private.h,
142 lib/Makefile.am, lib/jit_disasm.c, lib/jit_size.c, lib/lightning.c:
143 Minor updates for the new riscv port.
144
1452019-06-04 Paulo Andrade <pcpa@gnu.org>
146
147 * lib/jit_alpha.c lib/jit_ia64.c lib/jit_mips.c lib/jit_sparc.c:
148 Correct assertion of _jitc->regarg after emiting an instruction.
149 jit_carry may be set, but not an argument to the current instruction.
150
1512019-06-01 Paulo Andrade <pcpa@gnu.org>
152
153 * lib/lightning.c: Correct assertion on jit_unget_reg when the
154 argument is jit_carry, and jit_carry was not used in the
155 instruction.
156
1572019-06-01 Paulo Andrade <pcpa@gnu.org>
158
159 * include/lightning/jit_private.h: Remove no longer need
160 setmask field of jit_block_t and blockmask from jit_compiler_t.
161
162 * lib/lightning.c: Rework of register live and unknown state
163 information during jit generation. It no longer recurses nor
164 do dangerous bit unset of registers in unknown state. The
165 only pitfall known, that must be taken care now is that jmpr
166 (or jmpi to not a jit node) is treated as a function call, as
167 otherwise it would need to consider all registers live, and
168 spill/reload during all jit generation.
169
1702018-12-28 Paulo Andrade <pcpa@gnu.org>
171
172 * lib/jit_disasm.c: Release bfd handle. Thanks for patch to
173 Marc Nieper-Wißkirchen.
174
1752018-08-30 Paulo Andrade <pcpa@gnu.org>
176
177 * lib/jit_disasm.c: Add hints to select hppa disassembler.
178
179 * lib/jit_hppa-cpu.c: Correct address of vastart when all
180 argument registers were used as non vararg arguments.
181
182 * lib/jit_hppa-fpu.c: Disable load/store of rv,ix,rb where
183 rv is the value, ix is an register or integer offset and rb
184 is a base register. These should be better tested, as they do
185 not work on all environments (fail on qemu-hppa).
186
1872018-04-20 Paulo Andrade <pcpa@gnu.org>
188
189 * include/lightning/jit_private.h: Add new register classes to
190 flag float registers and double only registers, required for sparc64
191 where only low 32 bit fpr registers can be used for single precision
192 operations.
193 Add new 128 bit jit_regset_t type for sparc64 register set.
194
195 * include/lightning/jit_sparc.h, lib/jit_sparc-cpu.c, lib/jit_sparc-fpu.c,
196 lib/jit_sparc-sz.c, lib/jit_sparc.c: Update for 64 bits sparc.
197
198 * lib/lightning.c: Update for new jit_regset_t required for sparc64.
199
2002018-02-26 Paulo Andrade <pcpa@gnu.org>
201
202 * check/lightning.c, include/lightning.h: Add the new jit_va_push
203 interface. That should be called when passing a va_list to a C
204 function. This is required because on Alpha a va_list is passed
205 by value, and lightning does not know about data types, so, cannot
206 understand it is pushing a va_list as argument.
207
208 * lib/jit_names.c, lib/lightning.c: Minor changes for the new
209 jit_code_va_push.
210
211 * check/cva_list.c: Update only test case using jit_va_push, to
212 pass a va_list to a C function.
213
214 doc/body.texi: Better documentation of the varargs interface.
215
216 * jit_alpha.c, jit_alpha-cpu.c: Update to properly push a
217 C va_list and correctly calculate varargs offset.
218
219 * lib/jit_aarch64-sz.c, lib/jit_aarch64.c, lib/jit_alpha-sz.c,
220 lib/jit_arm-sz.c, lib/jit_arm.c, lib/jit_hppa-sz.c, lib/jit_hppa.c,
221 lib/jit_ia64-sz.c, lib/jit_ia64.c, lib/jit_mips-sz.c, lib/jit_mips.c,
222 lib/jit_ppc-sz.c, lib/jit_ppc.c, lib/jit_s390-sz.c, lib/jit_s390.c,
223 lib/jit_sparc-sz.c, lib/jit_sparc.c, lib/jit_x86-sz.c, lib/jit_x86.c:
224 Update for the new jit_va_push interface.
225
2262018-02-22 Paulo Andrade <pcpa@gnu.org>
227
228 * lib/jit_alpha-cpu.c: Always set t12 to the address of the
229 current function, to properly work on all systems. Previously
230 the shortcut did only work on Tru64. For Linux and glibc the
231 change is required.
232
2332018-02-22 Paulo Andrade <pcpa@gnu.org>
234
235 * lib/jit_aarch64.c, lib/jit_alpha.c, lib/jit_arm.c,
236 lib/jit_mips.c, lib/jit_ppc.c, lib/jit_sparc.c, lib/jit_x86.c:
237 Correct wrong logic in usage of jit_live in jit_retr. The
238 problem is that if a temporary is required during epilog,
239 the return register might be allocated, so, jit_live must always
240 be used.
241
2422018-01-31 Paulo Andrade <pcpa@gnu.org>
243
244 * lib/lightning.c: Avoid deep recursions when computing live
245 register ranges.
246
2472018-01-31 Paulo Andrade <pcpa@gnu.org>
248
249 * lib/jit_mips-cpu.c: Correct frame size and varargs
250 initialization for the n32 abi.
251 * lib/jit_mips.c, lib/jit_mips-fpu.c: Correct 32 bit abis
252 in big-endian.
253
2542017-09-13 Paulo Andrade <pcpa@gnu.org>
255
256 * configure.ac: Add check for binutils 2.29 prototype to the
257 disassembler function.
258 * lib/jit_disasm.c: Adapt for binutils 2.29 change.
259
2602017-06-09 Paulo Andrade <pcpa@gnu.org>
261
262 * include/lightning/jit_private.h, lib/lightning.c: Add a
263 second pass from start when computing register live ranges.
264 This should be used temporarily, and is required for certain
265 loop constructs, with several consecutive blocks not referencing
266 a live register.
267
2682016-05-05 Paulo Andrade <pcpa@gnu.org>
269
270 * lib/lightning.c: Correct wrong movr simplification,
271 remove no longer needed code to set return registers live
272 and update live register set when reaching a label boundary,
273 but do not descend if the block has been already visited.
274 The later need some tuning for complex code generation, where
275 it will still have issues.
276
2772015-11-30 Paulo Andrade <pcpa@gnu.org>
278
279 * doc/body.texi: Change documentation to no longer say
280 it is a variant of the Fibonacci sequence, and document
281 a proper implementation.
282 Thanks to Jon Arintok for pointing out that the Fibonacci
283 sequence generation was incorrect. It was documented, but
284 still confusing.
285
286 * check/fib.tst, check/fib.ok, check/bp.tst, check/bp.ok,
287 doc/ifib.c, doc/rbif.c: Implement a proper Fibonacci
288 sequence implementation.
289
2902015-07-03 Paulo Andrade <pcpa@gnu.org>
291
292 * lib/jit_mips-cpu.c: Correct definition of htonr_ul.
293 Correct prolog/epilog/va* routines to work on o64 abi.
294
295 * lib/jit_mips-fpu.c: Correct load of double literal
296 argument when not using a data buffer.
297 Remove alignment correction in vaarg_d if using the
298 new mips abi.
299
300 * lib/jit_mips.c: Correct code to allow creating variadic
301 jit functions when using the new mips abi.
302
303 * lib/jit_rewind.c: Minor adjust for rewind when using
304 the new mips abi, if there are varargs arguments in
305 registers.
306
3072015-06-06 Paulo Andrade <pcpa@gnu.org>
308
309 * lib/jit_ia64-cpu.c: Search backward for the last output
310 register used, otherwise would stop too early if a float
311 argument used the slot.
312 Correct offset of first va_list argument, and use proper
313 va_list abi.
314
315 * lib/jit_ia64-fpu.c: Add new functions to move a gpr
316 to a fpr register, to counterpart the ones that move a
317 fpr to a gpr. These are required to properly implement
318 jit_getarg*_{f,d} on complex prototypes, or variadic
319 jit functions.
320
321 * lib/jit_ia64-sz.c: Update for support to jit variadic
322 functions.
323
324 * lib/jit_ia64.c: Implement proper abi for variadic
325 jit functions.
326
3272015-06-04 Paulo Andrade <pcpa@gnu.org>
328
329 * lib/jit_rewind.c: New file implementing generic functions
330 to "rewind", or rewrite IR code sequences.
331
332 * include/lightning.h: Add several new codes, that previously
333 were a function call, that would synthesize the operation.
334 Now, there is a code for the operation, and a new flag to
335 know an operation is synthesized.
336
337 * include/lightning/jit_private.h: Add several new macros to
338 help construct synthesized IR code sequences.
339
340 * lib/Makefile.am: Update for lib/jit_rewind.c.
341
342 * lib/jit_disasm.c: Update for a small rework on jit_node_t,
343 so that --enable-devel-disassembler does not need a change
344 in the layout of jit_node_t.
345
346 * lib/jit_names.c: Update for the new codes.
347
348 * lib/jit_print.c: Update to print more readable output, and
349 flag synthesized IR code sequences.
350
351 * lib/jit_aarch64-sz.c, lib/jit_aarch64.c,
352 lib/jit_arm-sz.c, lib/jit_arm.c, lib/jit_x86-sz.c,
353 lib/jit_x86.c: Update for new synthesized IR code sequences.
354
355 * lib/jit_ppc-cpu.c, lib/jit_ppc-fpu., lib/jit_ppc-sz.c,
356 lib/jit_ppc.c, lib/jit_mips-cpu.c, lib/jit_mips-fpu.c,
357 lib/jit_mips-sz.c, lib/jit_mips.c, lib/jit_s390-fpu.c,
358 lib/jit_s390-sz.c, lib/jit_s390.c: Update for new synthesized
359 IR code sequences and correct bugs in the initial varargs
360 implementation support.
361
362 * lib/jit_alpha-sz.c, lib/jit_alpha.c, lib/jit_hppa-sz.c,
363 lib/jit_hppa.c, lib/jit_ia64-sz.c, lib/jit_ia64.c,
364 lib/jit_sparc-sz.c, lib/jit_sparc.c: Add generic, untested
365 support for the new synthesized IR code sequences. Known
366 most likely broken right now, and should be corrected once
367 access to these hosts is available.
368
369 * lib/lightning.c: Update for new IR codes, and add support
370 for not yet existing instructions that change third argument.
371
372 * size.c: Change to use different tables for LE and BE PowerPC.
373 Correct a wrong endif for x32.
374
3752015-05-25 Paulo Andrade <pcpa@gnu.org>
376
377 * check/cva_list.c: New file implementing a test to ensure
378 the value returned by jit_va_start is a valid C va_list.
379
380 * check/va_list.ok: New simple helper file, as now the
381 va_list.tst test is enabled.
382
383 * check/va_list.tst: Rewritten for an extensive variadic
384 jit functions test.
385
386 * check/Makefile.am: Update for the new tests.
387
388 * lib/jit_arm-cpu.c, lib/jit_arm-swf.c, lib/jit_arm-vfp.c,
389 lib/jit_arm.c: Correct broken software float in a previous
390 commit. Note that the hard float abi implementation is known
391 broken at this time, for special cases involving variadic
392 functions, and should be corrected next.
393
394 lib/jit_x86-cpu.c, lib/jit_x86-sz.c, lib/jit_x86.c: Correct
395 the jit_va_list_t semantics to match C va_list.
396
3972015-05-24 Paulo Andrade <pcpa@gnu.org>
398
399 * lib/Makefile.am: Bump library major. This is a preparation
400 for a rework that was due for quite some time, but that is
401 now required to properly implement variadic jit functions.
402 The rework is mainly required to know at prolog parsing, if
403 a function is variadic or not. This will benefit a few
404 backends, and is mandatory for the hard float arm abi.
405 The rework was already planned for quite some time, to
406 be able to use a variable stack framesize, and for leaf
407 functions optimization where applicable.
408 The change will be source compatible, but will change
409 some internals, and jit_code_t values, as some new will
410 be added.
411 The only behavior change is that, jit_arg_register_p may
412 change return value on hard float arm abi, if called before
413 or after jit_ellipsis. Common sense anyway, would say to
414 make that call after jit_ellipsis, but documentation
415 should be updated for it.
416
4172015-05-24 Paulo Andrade <pcpa@gnu.org>
418
419 * lib/jit_aarch64-fpu.c, lib/jit_aarch64.c: Correct base
420 aarch64 varargs code.
421
4222015-05-24 Paulo Andrade <pcpa@gnu.org>
423
424 * check/lightning.c: Clearly run check if clang is the system
425 compiler.
426
4272015-05-20 Paulo Andrade <pcpa@gnu.org>
428
429 * lib/jit_sparc-cpu.c, lib/jit_sparc-fpu.c, lib/jit_sparc.c:
430 Add base support to jit vararg functions to the sparc backend.
431
4322015-05-20 Paulo Andrade <pcpa@gnu.org>
433
434 * lib/jit_alpha-cpu.c, lib/jit_alpha-fpu.c, lib/jit_alpha.c:
435 Add base support to jit vararg functions to the alpha backend.
436
4372015-05-19 Paulo Andrade <pcpa@gnu.org>
438
439 * lib/jit_hppa-cpu.c, lib/jit_hppa-fpu.c, lib/jit_hppa.c:
440 Add base support to jit vararg functions to the hppa backend.
441
4422015-05-10 Paulo Andrade <pcpa@gnu.org>
443
444 * lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c, lib/jit_ia64.c:
445 Add base support to jit vararg functions to the ia64 backend.
446
4472015-05-10 Paulo Andrade <pcpa@gnu.org>
448
449 * lib/jit_ia64-fpu.c, lib/jit_ia64.c: Correct movi_d_w
450 and movi_f_w implementation to work when not using a
451 data buffer. This causes the check varargs.tst to
452 work when passing "-d" to the lightning test tool.
453
4542015-05-10 Paulo Andrade <pcpa@gnu.org>
455
456 * lib/jit_ia64.c: Implement inline assembly cache flush,
457 required on multiprocessor systems.
458
4592015-05-06 Paulo Andrade <pcpa@gnu.org>
460
461 * lib/jit_mips-cpu.c, lib/jit_mips-fpu.c, lib/jit_mips.c:
462 Add base support to jit vararg functions to the mips backend.
463 Currently only supported on the o32 abi, until access to a
464 n32 system is arranged.
465
4662015-05-05 Paulo Andrade <pcpa@gnu.org>
467
468 * lib/jit_ppc-cpu.c, lib/jit_ppc-fpu.c, lib/jit_ppc.c:
469 Add base support to jit vararg functions to the PowerPC backend.
470
4712015-05-02 Paulo Andrade <pcpa@gnu.org>
472
473 * lib/jit_s390-cpu.c, lib/jit_s390-fpu.c, lib/jit_s390.c:
474 Add base support to jit vararg functions to the s390 backend.
475
4762015-05-01 Paulo Andrade <pcpa@gnu.org>
477
478 * lib/jit_arm-cpu.c, lib/jit_arm-swf.c, lib/jit_arm-vfp.c,
479 lib/jit_arm.c: Add base support to jit vararg
480 functions to the arm backend.
481
4822015-04-30 Paulo Andrade <pcpa@gnu.org>
483
484 * lib/jit_aarch64-cpu.c, lib/jit_aarch64-fpu.c,
485 lib/jit_aarch64.c: Add base support to jit vararg
486 functions to the aarch64 backend.
487
4882015-04-27 Paulo Andrade <pcpa@gnu.org>
489
490 * include/lightning.h, include/lightning/jit_private.h,
491 lib/jit_names.c, lib/lightning.c: Add initial support
492 for the new jit_va_start, jit_va_arg, jit_va_arg_d, and
493 jit_va_end interfaces. The jit_va_start call is supposed
494 to return a va_list compatible pointer, but not yet
495 decided if it will be "declared" stdarg compatible,
496 as for now only x86 support has been added (and should
497 be compatible), but issues may arise on other backends.
498
499 * check/lightning.c: Add wrappers to call the new jit_va_*
500 interfaces.
501
502 * lib/jit_x86-cpu.c, lib/jit_x86.c: Implement the new
503 jit_va_* for x86.
504
505 * lib/jit_x86-sz.c: Add fields, but not yet fully updated,
506 as this is an intermediate commit.
507
508 * lib/jit_aarch64-sz.c, lib/jit_aarch64.c,
509 lib/jit_alpha-sz.c, lib/jit_alpha.c,
510 lib/jit_arm-sz.c, lib/jit_arm.c,

515 lib/jit_s390-sz.c, lib/jit_s390.c,
516 lib/jit_sparc-sz.c, lib/jit_sparc.c: Prepare for the
517 new jit_va_* interfaces. Not yet implemented, and will
518 cause an assertion if used.
519
520 * check/va_list.tst: Simple early test case, that works
521 on x86_64, x32, ix86, cygwin, and cygwin64.
522
5232015-02-17 Paulo Andrade <pcpa@gnu.org>
524
525 * include/lightning.h, include/lightning/jit_private.h,
526 lib/jit_aarch64-cpu.c, lib/jit_aarch64.c,
527 lib/jit_alpha-cpu.c, lib/jit_alpha.c,

533 lib/jit_s390-cpu.c, lib/jit_s390.c,
534 lib/jit_sparc-cpu.c, lib/jit_sparc.c,
535 lib/jit_x86-cpu.c, lib/jit_x86.c: Implement the new
536 jit_allocar(offs, size) interface, that receives
537 two integer registers arguments, allocates space
538 dynamically in the stack, returns the offset in
539 the first argument, and uses the second argument
540 for the size in bytes of the memory to be allocated.
541
542 * check/allocar.ok, check/allocar.tst: New files
543 implementing test cases for the new jit_allocar
544 interface.
545
546 * check/Makefile.am, check/lightning.c: Update for
547 the new test case and interface.
548
549 * doc/body.texi: Add documentation of the new
550 interface.
551
5522015-02-17 Paulo Andrade <pcpa@gnu.org>
553
554 * include/lightning/jit_x86.h, lib/jit_x86-cpu.c,
555 lib/jit_x86-x87.c: No longer make st(7) available.
556 Need to keep one x87 slots empty to avoid exceptions.
557 This has the side effect of no longer needing the
558 hackish emms instruction before a function call.
559
5602015-02-16 Paulo Andrade <pcpa@gnu.org>
561
562 * lib/lightning.c: Remove the jit_regno_patch bitfield
563 register fields before actual emit, as it is only really
564 used before emit, otherwise, on special conditions it
565 may consider live registers as dead during code emit.
566
5672015-02-15 Paulo Andrade <pcpa@gnu.org>
568
569 * lib/jit_x86-cpu.c, lib/jit_x86-sse.c, lib/jit_x86-x87.c:
570 Correct encoding of ldxr* stxr* in the x32 abi. If the
571 displacement register is negative, it would generate
572 a 64 bit instruction with a 32 bit unsigned displacement.
573
574 * check/ranger.tst, check/ranger.ok: New files, implementing
575 a test case for negative loads and stores. This is range.tst
576 converted to use registers instead of immediate offsets.
577
578 check/Makefile.am: Update for the new test case.
579
5802015-02-07 Paulo Andrade <pcpa@gnu.org>
581
582 * lib/jit_size.c: Preventively use at least 144 bytes
583 if JIT_INSTR_MAX is less than it. The logic is not
584 guaranteed to be 100% precise, it is mostly heuristics
585 to allocate a buffer with as close as possible size,
586 but a wrong value may cause code generation to write
587 past the end of the buffer.
588
5892015-02-03 Paulo Andrade <pcpa@gnu.org>
590
591 * lib/lightning.c: Correct the reason the bug in
592 simplify_stxi was not triggered before, it was due to
593 incorrectly resetting the value->code field, what was
594 causing it to never properly optimize:
595 stxi Im0 Rb0 Rt0
596 ldxi Rt1 Rb1 Im1
597 when Rb0 == Rb1, Rt0 == Rt1 and Im0 == Im1
598 There was another possible issue, that has been also
599 addressed in this commit, that would be the case of
600 Rbn == Rtn, where no redundancy removal is possible.
601
6022015-02-03 Paulo Andrade <pcpa@gnu.org>
603
604 * lib/lightning.c: Correct wrong check in simplify_stxi.
605 The test was incorrectly comparing the target register
606 and the displacement offset. This was a time bomb bug,
607 that would trigger in code like:
608 stxi Im0 Rb0 Rt0
609 stxi Im1 Rb1 Rt1
610 if Rb0 == Rb1 && Rt0 == Rt1 && Im0 == Rt1, that is,
611 the wrong check was Im0 == Rt1, instead of the supposed
612 Im0 == Imm1 (that was what the code mean't to do). It
613 was removing the second stxi assuming it was redundantly
614 generated; as that is not uncommon pattern on
615 translators generating jit.
616
6172015-02-02 Paulo Andrade <pcpa@gnu.org>
618
619 * configure.ac, include/lightning/jit_private.h,
620 lib/jit_aarch64.c, lib/jit_alpha.c, lib/jit_arm.c,
621 lib/jit_disasm.c, lib/jit_hppa.c, lib/jit_ia64.c,
622 lib/jit_mips.c, lib/jit_ppc.c, lib/jit_print.c,
623 lib/jit_s390.c, lib/jit_sparc.c, lib/jit_x86.c: Add a new
624 --enable-devel-disassembler option, that should be used
625 during development, or lightning debug. This option
626 intermixes previous jit_print and jit_disassemble
627 output, making it easier to visualize what lightning
628 call was used, and what code was generated.
629
6302015-01-31 Paulo Andrade <pcpa@gnu.org>
631
632 * lib/jit_arm-cpu.c, lib/jit_arm.c: Only limit to 24 bit
633 displacement non conditional jump in the same jit_state_t.
634
6352015-01-19 Paulo Andrade <pcpa@gnu.org>
636
637 * doc/body.texi: Reorder documentation, making jit_frame
638 and jit_tramp the lightning response to the need of
639 trampolines, continuations and tail call optimizations.
640 A pseudo code example of a factorial function was added.
641 Also added a section for description of the available
642 predicates.
643
644 * doc/fact.c: New file, implementing a simple example of
645 a translation of a trivial, recursive, tail call optimization
646 into lightning calls. This is the conversion to functional C
647 code of the example in doc/body.texi.
648
649 * doc/Makefile.am: Update for the next test case.
650
6512015-01-17 Paulo Andrade <pcpa@gnu.org>
652
653 * include/lightning.h, lib/jit_aarch64.c,
654 lib/jit_alpha.c, lib/jit_arm-vfp.c, lib/jit_arm.c,
655 lib/jit_hppa.c, lib/jit_ia64.c, lib/jit_mips.c,
656 lib/jit_ppc.c, lib/jit_s390.c, lib/jit_sparc.c,
657 lib/jit_x86.c: Add the new jit_arg_register_p predicate.
658 The predicate is expected to be used to know if an
659 argument is in a register, what would need special
660 handling if code that can overwrite non callee save
661 registers is executed.
662
663 * check/carg.c: New test case to check consistency and
664 expected usage of jit_arg_register_p.
665
666 * check/Makefile.am: Update for new test case.
667
6682015-01-17 Paulo Andrade <pcpa@gnu.org>

682 lib/jit_ppc.c, lib/jit_s390.c,
683 lib/jit_sparc.c, lib/jit_x86.c: Remove jit_arg_reg_p and
684 jit_arg_f_reg_p from a public header, and define it only
685 on port specific files where an integer offset is used
686 to qualify an argument identifier. Exported code expects
687 an opaque pointer (but of jit_node_t* type) to "qualify"
688 an argument identifier.
689 This patch, and the code review/simplification done during
690 it also corrected some bugs:
691 o Inconsistent jit_arg_d value of double argument after 3
692 integer arguments in arm for jit_functions; tested, C
693 functions were being properly called.
694 o Inconsistent use of getarg_{f,d} and putarg*_{f,d} on
695 s390 (32-bit) that happened to not have a proper test
696 case, as it would only happen for jit functions, and
697 tested, called C functions had proper arguments.
698 o Corrected a "last minute" correction that did not go
699 to the committed version, and would not compile on hppa,
700 due to bad _jit_putargi_d prototype definition.
701
7022015-01-17 Paulo Andrade <pcpa@gnu.org>
703
704 * doc/body.texi: Correct wrong/outdated information for
705 hton*, pusharg* and ret*, and add missing documentation
706 for rsb*, qmul*, qdvi* and putarg*.
707
7082015-01-15 Paulo Andrade <pcpa@gnu.org>
709
710 * configure.ac, lib/jit_disasm.c: Rewrite workaround
711 to apparent problem to initialize powerpc disassembler.
712
7132015-01-15 Paulo Andrade <pcpa@gnu.org>
714
715 * include/lightning.h, lib/jit_aarch64.c,
716 lib/jit_alpha.c, lib/jit_arm.c, lib/jit_hppa.c,
717 lib/jit_ia64.c, lib/jit_mips.c, lib/jit_ppc.c,
718 lib/jit_s390.c, lib/jit_sparc.c, lib/jit_x86.c:
719 Implement jit_putarg*. It works as a mix of jit_getarg*
720 and jit_pusharg*, in the way that the first argument is
721 a register or immediate, and the second is a pointer
722 returned by jit_arg*. The use of the interface is to change
723 values of arguments to the current jit function.
724
725 * check/put.ok, check/put.tst: New test cases exercising
726 the new jit_putarg* interface.
727
728 * check/Makefile.am, check/lightning.c: Update for the
729 new test case and interface.
730

734 lib/jit_s390-fpu.c, lib/jit_s390-sz.c, lib/jit_s390.c:
735 Renamed s390x* files to s390*.
736
737 * check/float.tst, check/lightning.c, configure.ac,
738 include/lightning.h, include/lightning/Makefile.am,
739 lib/Makefile.am, lib/jit_s390.c, lib/jit_size.c,

747 lib/jit_s390x.c, lib/jit_size.c, lib/lightning.c:
748 Add support for generating jit for s390 32 bit. This change
749 also removed %f15 from the list of temporaries fpr registers;
750 it was not being used, but if were, it would corrupt the
751 stack frame because the spill address would overwrite grp
752 offsets.
753
7542014-12-26 Paulo Andrade <pcpa@gnu.org>
755
756 * lib/jit_ppc-cpu.c, lib/jit_ppc.c: Correct some endianess issues
757 on the powerpc le backend.
758
7592014-12-26 Paulo Andrade <pcpa@gnu.org>
760
761 * lib/jit_ppc-cpu.c: Add mcrxr instruction emulation,
762 as this instruction has been phased out, and should be
763 implemented as a kernel trap.
764
7652014-12-26 Paulo Andrade <pcpa@gnu.org>
766
767 * lib/jit_arm.c: Better check for need to flush constants
768 before the pool being no longer reachable.
769
7702014-12-25 Paulo Andrade <pcpa@gnu.org>
771
772 * include/lightning.h: Split jit_htonr in the new 3 interfaces
773 jit_htonr_us, jit_htonr_ui and jit_htonr_ul, the later only
774 available on 64 bit. The plain/untyped jit_htonr macro call
775 maps to the wordsize one.

785 lib/jit_x86-cpu.c, lib/jit_x86-sz.c, lib/jit_x86.c:
786 Update backends for the new jit_htonr*.
787 * check/lightning.c, lib/jit_names.c, lib/lightning.c:
788 Update for the new jit_htonr* interfaces.
789 * check/Makefile.am: Update for new test cases.
790 * check/hton.ok, check/hton.tst: New test cases.
791

796 lib/jit_x86-sz.c, lib/jit_x86-x87.c, lib/jit_x86.c,
797 size.c: Implement support for the x32 abi. Built and
798 tested on Gentoo default/linux/amd64/13.0/x32 profile.
799
8002014-12-24 Paulo Andrade <pcpa@gnu.org>
801
802 * lib/jit_names.c: Add missing rsbi_f and rsbi_d strings.
803
8042014-12-21 Paulo Andrade <pcpa@gnu.org>
805
806 * lib/jit_arm.c: Call __clear_cache for every page.
807 This should only be required for older boards or
808 toolchain setup, but has been reported to be required
809 for lightning at some point.
810
8112014-12-21 Paulo Andrade <pcpa@gnu.org>
812
813 * lib/jit_arm.c: Correct check to guard overflow of index
814 of constants from program counter.
815
8162014-11-24 Paulo Andrade <pcpa@gnu.org>
817
818 * lib/lightning.c: Remove an optimization to calee save
819 registers that may incorrectly remove a jit_movr under
820 special conditions.
821
8222014-11-20 Paulo Andrade <pcpa@gnu.org>
823
824 * include/lightning/jit_ppc.h, lib/jit_ppc-cpu.c,
825 lib/jit_ppc.c: Add initial powerpc le support.
826
8272014-11-20 Paulo Andrade <pcpa@gnu.org>
828
829 * lib/jit_disasm.c: Change thumb or arm disassemble based on
830 jit code before disassembly.
831
832 * lib/jit_arm-cpu.c: Correct reversed arguments to LDRD and
833 STRD instructions, and correct checking for support of those.
834
835 * lib/jit_arm-swf.c: Correct wrong use of LDRD and STRD and
836 only use those if the register is even.
837
838 * check/check.arm.swf.sh, check/check.arm4.swf.sh: New files
839 to test LDRD and STRD, as well as the alternate code path
840 when those are not available, in the .arm4. test case.
841
842 * check/Makefile.am: Update for the new test cases.

849 lib/jit_s390x.c, lib/jit_sparc.c, lib/jit_x86.c:
850 Implement a private jit_flush call, that flushes
851 the cache, if applicable, aligning down to the
852 previous and up to the next page boundary.
853
8542014-11-08 Paulo Andrade <pcpa@gnu.org>
855
856 * check/ctramp.c: New file. It just repeats the test
857 of tramp.tst, but using two jit_state_t, what should
858 test possible issues with two contexts, and also validate
859 jit_tramp works on backends with function descriptions.
860
861 * check/Makefile.am: Update for new test case.
862
8632014-11-03 Paulo Andrade <pcpa@gnu.org>
864
865 * include/lightning/jit_mips.h: Do not make the t9 register
866 JIT_R11 (or JIT_R7 for n32 or n64 abi) available. Previously
867 it cause problems if one expects it to not be changed in a
868 function call. For example, calling a jit function, where it
869 really does not need to be changed.
870
8712014-10-26 Paulo Andrade <pcpa@gnu.org>

875 lib/jit_s390x.c, lib/jit_sparc.c, lib/jit_x86.c: Add an
876 assertion to all code generation "drivers" to ensure
877 _jitc->regarg is empty or in an expected state, after
878 translation of a lightning instruction to native code.
879 This change was a brute force test to find out other cases
880 of a temporary not being release (like was happening with
881 _bmsi and _bmci on x86), but no other case was found,
882 after running make check, with assertions enabled, on all
883 backends.
884
8852014-10-26 Paulo Andrade <pcpa@gnu.org>
886
887 * lib/jit_x86-cpu.c: Correct a register allocation leak in
888 _bmsi and _bmci.
889
8902014-10-25 Paulo Andrade <pcpa@gnu.org>
891
892 * lib/jit_disasm.c: Do not cause an fatal error if init_jit
893 fails in the jit_init_debug call.
894
8952014-10-24 Paulo Andrade <pcpa@gnu.org>
896
897 * lib/jit_ia64.c, lib/jit_ppc.c: Correct handling of function
898 descriptor when first prolog is a jit_tramp prolog. The
899 test case was using the same jit_context_t, so was not
900 triggering this condition.
901
902 * lib/jit_ppc-cpu.c: Properly handle jump displacements that
903 do not fit on 24 powerpc. This required changing from previous
904 "mtlr reg, blr" to "mtctr reg, bctr" to properly handle
905 the logic to "hide" function descriptors, but that would
906 also be required as the proper jit_jmpr when/if implementing
907 optimizations to leaf functions (was working with blr because
908 it is saved/reloaded in prolog/epilog).
909
9102014-10-21 Paulo Andrade <pcpa@gnu.org>
911
912 * include/lightning.h, lib/lightning.c: Add three predicates
913 to query information about labels. jit_forward_p(label)
914 will return non zero if the label is "forward", that is
915 need a call to jit_link(label), jit_indirect_p(label)
916 that returns non zero if the label was created with the
917 jit_indirect() call, and jit_target_p(label) that will
918 return non zero if there is at least one jump patched
919 to land at that label.
920
9212014-10-18 Paulo Andrade <pcpa@gnu.org>
922
923 * check/range.ok, check/range.tst: New test case designed
924 to catch incorrect code generation, usually due to incorrect
925 test of immediate size. The test checks a large amount of
926 encodings in "power of two" boundaries. This test exorcises
927 a significant amount of code paths that was previously not
928 tested.
929
930 * check/Makefile.am: Add range test to make check target.
931
932 * lib/jit_aarch64-cpu.c: Correct wrong address calculation
933 for stxi_c, stxi_s, stxi_i and stxi_l when the offset is
934 too large.
935
936 * lib/jit_mips-fpu.c: Correct wrong size test to check if
937 an immediate can be encoded in a float or double store.
938
939 * lib/jit_s390x-cpu.c: Correct inverted encoding to stxi_s
940 when the offset cannot be encoded, and fallbacks to an
941 alternate encoding in 2 instructions.
942
9432014-10-17 Paulo Andrade <pcpa@gnu.org>
944
945 * check/alu_rsb.ok, check/alu_rsb.tst: New files implementing
946 tests for jit_rsb*.
947
948 * check/Makefile.am, check/lightning.c, include/lightning.h,
949 lib/jit_aarch64-cpu.c, lib/jit_aarch64-fpu.c, lib/jit_aarch64-sz.c,

962 lib/jit_x86-sse.c, lib/jit_x86-sz.c, lib/jit_x86-x87.c,
963 lib/jit_x86.c, lib/lightning.c: Implement jit_rsb*. This
964 was a missing lightning 1.x interface, that on most
965 backends is synthesized, but on a few backends (hppa and ia64),
966 it can generate better code as on those there is, or the
967 only instruction with an immediate is in "rsb" format
968 (left operand).
969
9702014-10-17 Paulo Andrade <pcpa@gnu.org>
971
972 * lib/jit_names.c: New file with single definition of string
973 representation of lightning IR codes.
974
975 * size.c: Modified to append the code name in a C comment
976 after the maximum instruction size.
977
978 * lib/jit_print.c: Minor change to not duplicate jit_names.c
979 contents.
980
981 * lib/jit_aarch64-sz.c, lib/jit_alpha-sz.c, lib/jit_arm-sz.c,
982 lib/jit_hppa-sz.c, lib/jit_ia64-sz.c, lib/jit_mips-sz.c,
983 lib/jit_ppc-sz.c, lib/jit_s390x-sz.c, lib/jit_sparc-sz.c,
984 lib/jit_x86-sz.c: Rewritten to add string representation of
985 IR codes in a C comment.
986
9872014-10-14 Paulo Andrade <pcpa@gnu.org>
988
989 * lib/jit_aarch64-cpu.c, lib/jit_alpha-cpu.c, lib/jit_arm-cpu.c,
990 lib/jit_hppa-cpu.c, lib/jit_mips-cpu.c, lib/jit_ppc-cpu.c,
991 lib/jit_sparc-cpu.c: Implement or correct the internal
992 nop(count) call that receives an argument that tells the
993 modulo bytes to align the code for the next instruction.
994
995 * include/lightning.h, lib/lightning.c, lib/jit_aarch64.c,
996 lib/jit_alpha.c, lib/jit_arm.c, lib/jit_hppa.c, lib/jit_ia64.c,
997 lib/jit_mips.c, lib/jit_ppc.c, lib/jit_s390x.c, lib/jit_sparc.c,
998 lib/jit_x86.c: Implement the new jit_align() call that receive
999 an argument, that tells the modulo, in bytes, to align the
1000 next instruction. In most backends the only value that makes
1001 a difference is a value that matches sizeof(void*), as all
1002 other values usually are already automatically aligned in
1003 labels, but not guaranteed to be aligned at word size bytes.
1004
1005 * check/align.ok, check/align.tst: New files, implementing
1006 a simple test for the new jit_align() interface.
1007
1008 * check/Makefile.am, check/lightning.c, lib/jit_aarch64-sz.c,
1009 lib/jit_alpha-sz.c, lib/jit_arm-sz.c, lib/jit_hppa-sz.c,
1010 lib/jit_ia64-sz.c, lib/jit_mips-sz.c, lib/jit_ppc-sz.c,
1011 lib/jit_print.c, lib/jit_s390x-sz.c, lib/jit_sparc-sz.c,
1012 lib/jit_x86-sz.c: Update for the new jit_code_align code and
1013 the jit_align() interface.
1014
10152014-10-13 Paulo Andrade <pcpa@gnu.org>
1016
1017 * include/lightning.h, lib/jit_size.c, size.c: Use a
1018 symbolic value for the last IR code.
1019
10202014-10-12 Paulo Andrade <pcpa@gnu.org>
1021
1022 * include/lightning.h, include/lightning/jit_private.h,
1023 lib/jit_aarch64-cpu.c, lib/jit_alpha-cpu.c, lib/jit_arm-cpu.c,
1024 lib/jit_hppa-cpu.c, lib/jit_ia64-cpu.c, lib/jit_mips-cpu.c,
1025 lib/jit_ppc-cpu.c, lib/jit_s390x-cpu.c, lib/jit_sparc-cpu.c,
1026 lib/jit_x86-cpu.c, lib/lightning.c: Implement the new
1027 jit_frame and jit_tramp interfaces, that allow writing
1028 trampoline like calls, where a single dispatcher jit buffer
1029 is written, and later other jit buffers are created, with
1030 the same stack frame layout as the dispatcher. This is the
1031 logic that GNU Smalltalk used in lightning 1.x, and is required
1032 to make a sane port for lighting 2.x.
1033
1034 * jit_ia64-cpu.c: Implement support for jit_frame and jit_tramp,
1035 and also correct wrong encoding for B4 instructions, that
1036 implement jmpr, as well as correct reverse logic in _jmpr,
1037 that was moving the branch register to the jump register,
1038 and not vice-versa.
1039 Also, if a stack frame is to be assumed, always assume it may
1040 call a function with up to 8 arguments, regardless of the
1041 hint frame argument.
1042
1043 * lib/jit_arm.c: Add a new must_align_p() interface to ensure
1044 function prologs are always aligned. This condition was
1045 previously always true, somewhat by accident, but with
1046 jit_tramp it is not guaranteed.
1047
1048 * jit_ia64-cpu.c: lib/jit_ppc.c: Add minor special handling
1049 required to implement jit_tramp, where a function descriptor
1050 should not be added before a prolog, as jit_tramp means omit
1051 prolog.
1052
1053 * check/lightning.c: Update test driver for the new interfaces.
1054
1055 * check/Makefile.am, check/tramp.tst, check/tramp.ok: Add
1056 a simple test and example of the jit_frame and jit_tramp
1057 usage implementing a simple Fibonacci function using a
1058 simulation of an interpreter stack and how it would handle
1059 state in language specific variables.
1060
1061 * doc/body.texi: Add documentation for jit_frame and
1062 jit_tramp.
1063
10642014-09-29 Paulo Andrade <pcpa@gnu.org>
1065
1066 * lib/jit_aarch64.c, lib/jit_alpha.c, lib/jit_arm.c,
1067 lib/jit_hppa.c, lib/jit_ia64.c, lib/jit_mips.c,
1068 lib/jit_ppc.c, lib/jit_s390x.c, lib/jit_sparc.c,
1069 lib/jit_x86.c, lib/lightning.c: Allow jit_jmpi on a
1070 target that is not a node. This may lead to hard to
1071 debug code generation, but is a required feature for
1072 certain generators, like the ones that used lightning
1073 1.2x. Note that previously, but not really well
1074 documented, it was instructed to use:
1075 jit_movi(rn, addr); jit_jmpr(rn);
1076 but now, plain:
1077 jit_patch_abs(jit_jmpi(), addr);
1078 should also work.
1079
10802014-09-24 Paulo Andrade <pcpa@gnu.org>
1081
1082 * lib/jit_x86-sz.c: Generate information about instruction
1083 lengths for more precise calculation of buffer size on
1084 Windows x64. This change is specially important because
1085 the maximum instruction length is larger than other
1086 systems, what could cause an out of bounds write on
1087 special conditions without this update.
1088
10892014-09-24 Paulo Andrade <pcpa@gnu.org>
1090
1091 * check/lightning.c: Add workaround to conflicting global
1092 optind variable in cygwin binutils that have an internal
1093 getopt* implementation.
1094
1095 * lib/jit_x86-cpu.c: Add a simple define ffsl ffs if building
1096 for 32 bit and there is no ffsl function.
1097
10982014-09-24 Paulo Andrade <pcpa@gnu.org>
1099
1100 * check/lightning.c: Add a hopefully temporary kludge to not use
1101 sprintf and sscanf returned by dlsym. This is required to pass
1102 the varargs test.
1103
1104 * include/lightning/jit_private.h: Use symbolic name for first
1105 integer register argument, as this is different in sysv and
1106 win64 abi.
1107
1108 * include/lightning/jit_x86.h: Add conditionals and definitions
1109 for Windows x64 (under __CYGWIN__ preprocessor conditional).
1110
1111 * lib/jit_x86-cpu.c: Correct one instruction encoding bug, that
1112 was working by accident. Only use rax to rdx for some byte
1113 operations to work on compatibility mode (that is, to generate
1114 the proper encoding, instead of actually generating encoding
1115 for high byte registers, e.g. %bh).
1116 Add proper prolog and epilog for windows x64.
1117
1118 * lib/jit_x86-sse.c: Correct a swapped rex prefix for float
1119 operations.
1120
1121 * lib/jit_x86.c: Adjust to support Windows x64 abi.
1122
1123 * check/check.x87.nodata.sh: New file, previously used but that
1124 was missing git.
1125
11262014-09-07 Paulo Andrade <pcpa@gnu.org>
1127
1128 * lib/lightning.c: Mark all registers advertised as live, as
1129 per jit_callee_save_p as live whenever reaching a jump that
1130 cannot be tracked. This is a rethink of the previous commit,
1131 and is a better approach, otherwise there would not be much
1132 sense on relying on jit_callee_save_p if it could not be
1133 trusted.
1134
1135 * check/jmpr.tst, check/jmpr.ok: New files implementing a very
1136 simple test case, that would actually cause an assertion on
1137 code before the change to only mark as live when reaching a
1138 jump that could not tracked, the actually advertised as callee
1139 save registers.
1140
1141 check/Makefile.am: Update for new jmpr test case.
1142
11432014-09-01 Paulo Andrade <pcpa@gnu.org>
1144
1145 * lib/lightning.c: Do not mark all registers in unknown state
1146 as live on jit_jmpr, or jit_jmpi to an absolute address. Instead,
1147 treat it as a function call, and only consider JIT_Vn registers
1148 as possibly live.
1149
11502014-08-29 Paulo Andrade <pcpa@gnu.org>
1151
1152 * doc/body.texi: Add a proper info menu entry for
1153 GNU lightning.
1154
1155 * doc/version.texi: Regenerate.
1156
11572014-08-16 Paulo Andrade <pcpa@gnu.org>
1158
1159 * lib/jit_aarch64-cpu.c, lib/jit_aarch64-fpu.c,
1160 lib/jit_arm-cpu.c, lib/jit_arm-vfp.c,
1161 lib/jit_hppa-cpu.c, lib/jit_hppa-fpu.c,

1167 lib/jit_x86-cpu.c, lib/jit_x86-sse.c,
1168 lib/jit_x86-x87.c: Review generation of all branch
1169 instructions and always adds the jit_class_nospill
1170 bitfield for temporary registers that cannot be spilled
1171 because the reload would be after a conditional jump; the
1172 patch only adds an extra assertion. These conditions do
1173 not happen on documented lightning usage, but can happen
1174 if one uses the not exported jit_get_reg and jit_unget_reg
1175 calls and cause enough register starvation.
1176
11772014-08-16 Paulo Andrade <pcpa@gnu.org>
1178
1179 * lib/jit_alpha.c: Correct wrong bitmask of most argument
1180 float register arguments, that were being set as callee
1181 save instead of argument registers class.
1182
11832014-08-16 Paulo Andrade <pcpa@gnu.org>
1184
1185 * lib/jit_arm-sz.c: Regenerate table of known maximum
1186 instruction sizes for the software float fallback,
1187 that implements "virtual" float registers in the stack
1188 and operations as calls to libgcc.
1189
1190 * size.c: Correct typo in the generated jit_arm-sz.c file.
1191
11922014-08-10 Paulo Andrade <pcpa@gnu.org>
1193
1194 * include/lightning/jit_alpha.h, lib/jit_alpha-cpu.c,
1195 lib/jit_alpha-fpu.c, lib/jit_alpha-sz.c, lib/jit_alpha.c:
1196 New files implementing a lightning Alpha port. Thanks
1197 to Trent Nelson and snakebit.net staff for providing access
1198 to an Alpha system.
1199
1200 * check/float.tst, check/lightning.c, configure.ac,
1201 include/lightning.h, include/lightning/Makefile.am,
1202 include/lightning/jit_private.h, lib/Makefile.am,
1203 lib/jit_disasm.c, lib/jit_size.c, lib/lightning.c:
1204 Minor changes to adapt for the new Alpha port.
1205
12062014-08-10 Paulo Andrade <pcpa@gnu.org>
1207
1208 * lib/lightning.c: Always mark JIT_RET and JIT_FRET as
1209 live in a function epilog. This is required because
1210 on some ports a complex sequence, allocating one or more
1211 registers, may be required to jump from a ret* to the
1212 epilog, and the lightning api does not have annotations
1213 to know if a function returns a value, or the type of
1214 the return value.
1215
12162014-08-10 Paulo Andrade <pcpa@gnu.org>
1217
1218 * lib/lightning.c: Change the correct live bitmask of
1219 return registers after a function call in jit_update.
1220
12212014-08-10 Paulo Andrade <pcpa@gnu.org>
1222
1223 * lib/lightning.c: Change assertions to have an int
1224 result and correct a bad bit mask assertion.
1225
12262014-08-10 Paulo Andrade <pcpa@gnu.org>
1227
1228 * lib/jit_aarch64.c: Correct bad setup for assertion
1229 of consistency before a patch.
1230
12312014-08-10 Paulo Andrade <pcpa@gnu.org>
1232
1233 * lib/jit_mips-cpu.c: Correct typo in the jit_bmsr
1234 implementation that was using the wrong test result
1235 register.
1236
12372014-07-28 Paulo Andrade <pcpa@gnu.org>
1238
1239 * lib/jit_memory.c: Do not call free on NULL pointers.
1240
1241 * include/lightning/jit_private.h, lib/jit_note.c,
1242 lib/lightning.c: Add a wrapper to memcpy and memmove
1243 to not actually call those functions with a zero size
1244 argument, and likely also a null src or dst.
1245
12462014-07-27 Paulo Andrade <pcpa@gnu.org>
1247
1248 * include/lightning/jit_private.h, lib/jit_disasm.c,
1249 lib/lightning.c: Remove the global jit_progname variable.
1250 It was being only used in jit_init_debug, that is called
1251 from init_jit, so, just pass an argument.
1252
12532014-07-27 Paulo Andrade <pcpa@gnu.org>
1254
1255 * doc/body.texi: Add note that jit_set_memory_functions
1256 should be called before init_jit, because init_jit
1257 itself may call the memory wrappers.
1258
12592014-04-22 Paulo Andrade <pcpa@gnu.org>
1260
1261 * lib/jit_arm.c: Do not get confused with default settings
1262 if /proc is not mounted on Linux specific code path.
1263
12642014-04-09 Paulo Andrade <pcpa@gnu.org>
1265

1267 include/lightning/jit_hppa.h, include/lightning/jit_ia64.h,
1268 include/lightning/jit_mips.h, include/lightning/jit_ppc.h,
1269 include/lightning/jit_private.h, include/lightning/jit_s390x.h,
1270 include/lightning/jit_sparc.h, include/lightning/jit_x86.h:
1271 Do not add jit_regset_t, JIT_RA0, and JIT_FA0 to the installed
1272 header file. These types and definitions are supposed to be
1273 only used internally.
1274
12752014-04-05 Paulo Andrade <pcpa@gnu.org>
1276
1277 * lib/jit_arm-cpu.c: Only adjust stack pointer in prolog if
1278 need stack space, that is, do not emit a nop instruction
1279 subtracting zero from the stack pointer.
1280
12812014-04-04 Paulo Andrade <pcpa@gnu.org>
1282
1283 * lib/jit_disasm.c: Correct a crash in the doc/printf example
1284 on arm due to releasing the data_info information in
1285 jit_clear_state. This is a special case for arm only, and
1286 actually, only armv5 or older uses the data_info buffer,
1287 or when forcing arm instruction set mode besides thumb
1288 available.
1289
12902014-12-03 Paulo Andrade <pcpa@gnu.org>
1291
1292 * doc/body.texi: Write detailed description and examples for
1293 jit_get_memory_functions, jit_set_memory_functions,
1294 jit_get_code, jit_set_code, jit_get_data and jit_set_data.
1295
12962014-12-03 Paulo Andrade <pcpa@gnu.org>
1297
1298 * include/lightning.h, include/lightning/jit_private.h,
1299 lib/lightning.c: Implement the new jit_set_data() interface,
1300 and the new jit_get_data() helper. Like jit_set_code(),
1301 jit_realize() should be called before jit_set_data().
1302 The most common usage should be jit_set_data(JIT_DISABLE_DATA
1303 | JIT_DISABLE_NOTE), to force synthesize any float/double
1304 constant in the stack and not generate any debug information.
1305
1306 * lib/jit_note.c: Minor change to debug note generation as
1307 now it uses an alternate temporary data buffer during constants
1308 and debug generation to accommodate the possibility of the user
1309 setting an alternate data buffer.
1310
1311 * lib/jit_hppa-fpu.c, lib/jit_s390x.c, lib/jit_s390x-cpu.c,
1312 lib/jit_s390x-fpu.c, lib/jit_sparc.c, lib/jit_sparc-fpu.c,
1313 lib/jit_x86-sse.c, lib/jit_x86-x87.c: Implement jit_set_data.
1314
1315 * lib/jit_hppa-sz.c, lib/jit_sparc-sz.c, lib/jit_x86-sz.c,
1316 lib/jit_s390x-sz.c: Update for several instructions that now
1317 have a different maximum length due to jit_set_data.
1318
1319 * lib/jit_mips-fpu.c: Implement jit_set_data, but missing
1320 validation on n32 and n64 abis (and/or big endian).
1321
1322 * lib/jit_mips-sz.c: Update for changes in o32.
1323
1324 * lib/jit_ppc-fpu.c: Implement jit_set_data, but missing
1325 validation on Darwin PPC.
1326
1327 * lib/jit_ppc-sz.c: Update for changes in powerpc 32 and
1328 64 bit.
1329
1330 * lib/jit_ia64-fpu.c: Implement untested jit_set_data.
1331
1332 * TODO: Add note to list ports that were not tested for the
1333 new jit_set_data() feature, due to no longer having access
1334 to them.
1335
1336 * check/nodata.c: New file implementing a simple test exercising
1337 several different conditions created by jit_set_data().
1338
1339 * check/check.nodata.sh: New file implementing a wrapper
1340 over the existing *.tst files, that runs all tests without
1341 using a data buffer for constants; only meaningful (and
1342 enabled) on architectures that used to store float/double
1343 constants on a read only data buffer.
1344
1345 * configure.ac, check/Makefile.am: Update for the new test
1346 cases.
1347
1348 * check/lightning.c: Implement the new "-d" option that
1349 sets an internal flag to call jit_set_data() disable
1350 constants and debug, that is, using only a pure code
1351 buffer.
1352
13532014-11-03 Paulo Andrade <pcpa@gnu.org>
1354
1355 * include/lightning.h, include/lightning/jit_private.h,
1356 lib/lightning.c: Implement the new jit_set_code() interface,
1357 that allows instructing lightning to use an alternate code
1358 buffer. The new jit_realize() function should be called
1359 before jit_set_code(), and usually call jit_get_code()
1360 to query the amount of bytes expected to be required for
1361 the code.
1362
1363 * lib/jit_size.c: Minor update to have less chances of
1364 miscalculating the code buffer by starting the counter
1365 with the size of the longest instruction instead of zero,
1366 as code emit fails if at any moment less than the longest
1367 instruction bytes are available.
1368
1369 * check/setcode.c: New file implementing some basic tests
1370 of the new jit_set_code() interface.
1371
1372 * check/Makefile.am: Update for newer test case.
1373
13742014-06-03 Paulo Andrade <pcpa@gnu.org>
1375
1376 * include/lightning.h, lib/lightning.c: Add the new
1377 jit_indirect() call, that returns a special label node,
1378 and tells lightning that the label may be the target of
1379 an indirect jump.
1380
1381 * doc/body.texi: Document the new jit_indirect() call, and
1382 add examples of different ways to create labels and branches.
1383
13842014-23-02 Paulo Andrade <pcpa@gnu.org>
1385
1386 * lib/jit_x86.c: Rewrite previous patch to inline save/restore
1387 because clobbering %ebx in x86 is treated as an error
1388 (jit_x86.c:239:5: error: PIC register clobbered by 'ebx' in 'asm').
1389
13902014-19-02 Paulo Andrade <pcpa@gnu.org>
1391
1392 * lib/jit_x86.c: Rewrite incorrect inline assembly that could
1393 truncate a variable in a callee save register. Now it simply
1394 tells gcc that the register is clobbered, instead of using a
1395 *32 bit* swap with a temporary variable. The problem only
1396 happens when compiling with optimization.
1397
13982014-19-02 Paulo Andrade <pcpa@gnu.org>
1399
1400 * include/lightning/jit_aarch64.h, include/lightning/jit_arm.h,
1401 include/lightning/jit_hppa.h, include/lightning/jit_ia64.h,
1402 include/lightning/jit_mips.h, include/lightning/jit_ppc.h,
1403 include/lightning/jit_s390x.h, include/lightning/jit_sparc.h,
1404 include/lightning/jit_x86.h: Change jit_regset_t to an
1405 unsigned type, to allow safe right shift.
1406
1407 * lib/lightning.c: Rewrite jit_regset_scan1 to allow easier
1408 compiler optimization.
1409
14102013-12-03 Paulo Andrade <pcpa@gnu.org>
1411
1412 * lib/jit_x86-x87.c: Correct wrong optimization when
1413 loading the log(2) constant.
1414
14152013-12-03 Paulo Andrade <pcpa@gnu.org>
1416
1417 * lib/jit_x86-cpu.c: Use the emms instruction before
1418 calling any function. This is particularly important
1419 when using c99 complex functions as it can easily
1420 overflow the x87 stack due to the way lightning uses
1421 the x87 stack as a flat register file.
1422
14232013-12-02 Paulo Andrade <pcpa@gnu.org>
1424
1425 * lib/jit_x86-x87.c: Correct wrong code generation due
1426 to comparing the base and not the value register with
1427 %st(0) in stxi_f.
1428
14292013-12-02 Paulo Andrade <pcpa@gnu.org>
1430
1431 * lib/jit_x86-x87.c, lib/jit_x86.c: Use 8 bytes aligned
1432 stack offset for float/double x87 to/from sse move.
1433
14342013-11-27 Paulo Andrade <pcpa@gnu.org>
1435
1436 * configure.ac, lib/jit_arm-swf.c, lib/jit_arm.c: Add
1437 changes that should at least allow building lightning
1438 on Apple iOS7.
1439
14402013-10-08 Paulo Andrade <pcpa@gnu.org>
1441
1442 * lib/jit_ppc-cpu.c: Correct wrong shortcut for ldxi_l with
1443 a zero offset, that was calling ldr_i instead of ldr_l.
1444
14452013-10-08 Paulo Andrade <pcpa@gnu.org>
1446
1447 * include/lightning/jit_arm.h, lib/jit_arm-cpu.c: Do not use
1448 by default load/store instructions that map to ldrt/strt.
1449 There is already the long displacement version for positive
1450 offsets, and when using a (shorter) negative offset it does
1451 not map to ldrt/strt. At least on qemu strt may cause
1452 reproducible, but unexpected SIGILL.
1453
14542013-10-08 Paulo Andrade <pcpa@gnu.org>
1455
1456 * lib/jit_arm-vfp.c: Correct wrong load/store offset
1457 calculation when the displacement is constant but too
1458 large to use an instruction with an immediate offset.
1459
14602013-10-07 Paulo Andrade <pcpa@gnu.org>
1461
1462 * check/self.c: Extend tests to validate jit_callee_save_p
1463 does not cause an assertion on valid arguments, and test
1464 extra registers defined on some backends.
1465
1466 * configure.ac: Do not ignore environment CFLAGS when
1467 checking if need to test runtime configurable options,
1468 like use x87 when sse2 is available, arm instruction set
1469 instead of thumb, etc.
1470
1471 * include/lightning/jit_arm.h: Correct wrong jit_f macro
1472 definition.
1473
519a9ea1 1474 * include/lightning/jit_ia64.h, include/lightning/jit_ppc.h:
4a71579b
PC
1475 Correct wrong jit_r macro definition.
1476
1477 * lib/jit_x86-x87.c, lib/jit_x86.c: Actually use the
1478 reserved stack space for integer to/from float conversion.
1479 The stack space was also changed to ensure it is 8 bytes
1480 aligned. Also, for Solaris x86 in 32 bit mode, an alternate
1481 truncr_d was implemented because for some reason it is
1482 failing with SIGILL if using the "fisttpl" instructions,
1483 that must be available on p6 or newer, but for the sake of
1484 making all tests pass, implement a 486 or newer sequence
1485 if "sun" is defined.
1486
14872013-10-03 Paulo Andrade <pcpa@gnu.org>
1488
1489 * include/lightning/jit_mips.h, lib/jit_mips-cpu.c,
1490 lib/jit_mips-sz.c, lib/jit_mips.c, size: Build and
1491 pass all test cases on Irix big endian mips using
1492 the 64 bit abi.
1493
14942013-10-02 Paulo Andrade <pcpa@gnu.org>
1495
1496 * include/lightning/jit_mips.h: Add proper mips abi detection.
1497
14982013-09-30 Paulo Andrade <pcpa@gnu.org>
1499
1500 * lib/jit_print.c: Do not crash if calling jit_print from
1501 gdb before actually emitting code.
1502
1503 * lib/lightning.c: Correct misplaced check for already
1504 visited blocks on conditional branches, what was preventing
1505 proper merge live bit masks of forward blocks.
1506
15072013-09-30 Paulo Andrade <pcpa@gnu.org>
1508
1509 * lib/jit_x86-cpu.c: Correct not properly tested case of using
1510 %r12 as index register, what was causing an invalid assertion.
1511 %r12 is mapped to the "extra" JIT_R3 register, and test cases
1512 only test "standard" lightning registers.
1513
15142013-09-28 Paulo Andrade <pcpa@gnu.org>
1515
1516 * lib/jit_ia64.c: Minor change to force collecting the maximum
1517 instruction length in the --enable-devel-get-jit-size build
1518 mode. The actual generated file did not change because the
1519 sampling was large enough that it had already collected proper
1520 information in the previously slightly buggy code (not forcing
1521 a sync of the instructions that could be combined).
1522
15232013-09-27 Paulo Andrade <pcpa@gnu.org>
1524
1525 * lib/jit_arm.c: Correct build when disassembler is
1526 disabled.
1527
15282013-09-25 Paulo Andrade <pcpa@gnu.org>
1529
1530 * lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c: Correct some
1531 off by one range checks (that were only accepting values
1532 one less than the maximum allowed) and an invalid test
1533 condition check that was forcing it to always use
1534 indirect jumps even when reachable with an immediate
1535 displacement.
1536
15372013-09-24 Paulo Andrade <pcpa@gnu.org>
1538
1539 * lib/jit_aarch64-sz.c, lib/jit_arm-sz.c, lib/jit_hppa-sz.c,
1540 lib/jit_ia64-sz.c, lib/jit_mips-sz.c, lib/jit_ppc-sz.c,
1541 lib/jit_s390x-sz.c, lib/jit_size.c, lib/jit_sparc-sz.c,
1542 lib/jit_x86-sz.c: New files implementing static tables
1543 with longest known instructions length generated to match
1544 a lightning instruction. These tables should make it easier
1545 to make it very unlikely to ever miscalculate, or by too
1546 much, the size of a code buffer.
1547
1548 * lib/jit_size.c: New file that aids to either collect
1549 jit code size information, or use the information depending
1550 on build options.
1551
1552 * size.c: New helper file that parses input for, and create
1553 an initial jit_$arch-sz.c file, that needs some minor edit
1554 for arches with multiple configurations.
1555
1556 * configure.ac, Makefile.am: Add the new, devel mode only
1557 --enable-devel-get-jit-size configure option, that sets
1558 compile time flags to collect jit code size information,
1559 that will be used as input for the "noinst size program".
1560
1561 * lib/jit_aarch64.c, lib/jit_arm.c, lib/jit_disasm.c,
1562 lib/jit_hppa.c, lib/jit_ia64.c, lib/jit_memory.c,
1563 lib/jit_mips.c, lib/jit_ppc.c, lib/jit_s390x.c,
1564 lib/jit_sparc.c, lib/jit_x86.c, lib/lightning.c: Minor
1565 changes for the --enable-devel-get-jit-size build mode,
1566 as well as the "production build mode" with jit code
1567 size information.
1568
15692013-09-14 Paulo Andrade <pcpa@gnu.org>
1570
1571 * include/lightning.h, lib/lightning.c: Add the new
1572 jit_pointer_p interface, that returns a boolean value
1573 telling if the pointer argument is inside the jit
1574 code buffer. This is useful to avoid the need to add
1575 extra labels and calls to jit_address to figure bounds
1576 of code buffer, and still keep internal data private.
1577
15782013-09-13 Paulo Andrade <pcpa@gnu.org>
1579
1580 * include/lightning.h, include/lightning/jit_private.h,
1581 lib/jit_note.c: Change the code argument of jit_get_note
1582 to a jit_pointer_t and make jit_get_note a public interface.
1583 It was intended so since start, as a way to map an offset
1584 in the code to a function name, file name and line number
1585 mapping.
1586
15872013-09-11 Paulo Andrade <pcpa@gnu.org>
1588
1589 * doc/body.texi: Correct reversed arguments in example of
1590 usage in a (possibly) multi threaded, multiple jit_state_t
1591 environments.
1592
1593 * include/lightning/jit_arm.h, include/lightning/jit_private.h,
1594 lib/jit_arm-cpu.c, lib/jit_arm.c: Make a previously, non
1595 documented, global state private to the related jit_state_t
1596 generating code.
1597
15982013-09-10 Paulo Andrade <pcpa@gnu.org>
1599
1600 * check/self.c, check/self.ok: New files implementing simple
1601 consistency check assertions. At first validating some macros
1602 that use values from different sources agree.
1603
1604 * check/Makefile.am: Update for the new test case.
1605
1606 * include/lightning.h, lib/lightning.c: Add the new
1607 jit_callee_save_p() call, that is intended to be used when
1608 writing complex code using lightning, so that one does not
1609 need to verify what backend is being used, or have access to
1610 private data, to query if a register is callee save or not;
1611 on several backends the scratch registers are actually callee
1612 save.
1613
1614 * include/lightning/jit_aarch64.h, include/lightning/jit_arm.h,
1615 include/lightning/jit_hppa.h, include/lightning/jit_mips.h,
1616 include/lightning/jit_ppc.h, include/lightning/jit_sparc.h,
1617 include/lightning/jit_x86.h: Add an explicit definition for
1618 JIT_R3-JIT_Rn, JIT_V3-JIT_Vn and JIT_F6-JIT_Fn when applicable.
1619 This allows one to write code based on "#if defined(JIT_XN)"
1620 and therefore, not need to check what is the current backend
1621 or have access to private data structures. This is particularly
1622 useful when writing virtual machines with several specialized,
1623 global registers.
1624
1625 * lib/jit_ia64.c: Properly flag the callee save general
1626 purpose registers as such, so that jit_callee_save_p() works
1627 as intended.
1628
16292013-09-10 Paulo Andrade <pcpa@gnu.org>
1630
1631 * check/lightning.c, configure.ac: Conditionally use the
1632 code written to workaround a bug in the Hercules emulator,
1633 as isnan and isinf are not available at least on HP-UX ia64.
1634
16352013-09-10 Paulo Andrade <pcpa@gnu.org>
1636
1637 * lib/jit_s390x-cpu.c: Spill/reload correct callee save
1638 float registers.
1639
16402013-09-10 Paulo Andrade <pcpa@gnu.org>
1641
1642 * lib/jit_hppa-cpu.c: Correct code to call a function stored
1643 in a register or a patched function address.
1644
16452013-09-10 Paulo Andrade <pcpa@gnu.org>
1646
1647 * lib/jit_ia64-cpu.c: Correct incorrect logic when restoring
1648 the value of the "r2" callee save register.
1649
16502013-08-29 Paulo Andrade <pcpa@gnu.org>
1651
1652 * lib/jit_arm-cpu.c, lib/jit_arm.c: Correct wrong test and update
1653 of the thumb offset information, when checking if needing to
1654 patch a jump from arm to thumb mode. The problem would happen when
1655 remapping the code buffer, and the new address being lower than
1656 the previous one.
1657
16582013-08-26 Paulo Andrade <pcpa@gnu.org>
1659
1660 * configure.ac: Extend FreeBSD test to also handle NetBSD.
1661
1662 * lib/jit_x86-cpu.c: Correct wrongly defined offset type of
1663 ldxi_ui. Problem detected when building on NetBSD.
1664
1665 * lib/lightning.c: Adjust code to handle NetBSD mremap,
1666 where arguments do not match Linux mremap.
1667
16682013-08-26 Paulo Andrade <pcpa@gnu.org>
1669
1670 * lib/jit_ppc.c: Correct C sequence point problem miscalculating
1671 the actual function address in a function descriptor. Problem
1672 happens with gcc 4.8.1 at least.
1673
16742013-08-11 Paulo Andrade <pcpa@gnu.org>
1675
1676 * lib/jit_s390x-cpu.c: Correct code checking if immediate
1677 fits instruction, but using the negated value.
1678
16792013-07-28 Paulo Andrade <pcpa@gnu.org>
1680
1681 * include/lightning/jit_s390x.h, lib/jit_s390x-cpu.c,
1682 lib/jit_s390x-fpu.c, lib/jit_s390x.c: New files
1683 implementing the new s390x port.
1684
1685 * configure.ac, include/lightning.h,
1686 include/lightning/Makefile.am,
1687 include/lightning/jit_private.h,
1688 lib/Makefile.am, lib/jit_disasm.c, lib/lightning.c:
1689 Minor adaptation for the new s390x backend.
1690
1691 * check/float.tst: Update for the s390x result of
1692 truncating +Inf to integer.
1693
1694 * check/qalu_mul.tst: Add extra test cases to better test
1695 high word of signed multiplication as the result is
1696 adjust from unsigned multiplication on s390x.
1697
16982013-07-28 Paulo Andrade <pcpa@gnu.org>
1699
1700 * check/lightning.c: Do not assume casting a double NaN or
1701 Inf to float will produce the expected float NaN or Inf.
1702 This is not true at least under s390x.
1703
17042013-07-28 Paulo Andrade <pcpa@gnu.org>
1705
1706 * check/check.arm.sh, check/check.sh, check/check.swf.sh,
1707 check/check.x87.sh: Properly check test programs output,
1708 not just rely on the test program self testing the results
1709 and not crashing.
1710
17112013-07-28 Paulo Andrade <pcpa@gnu.org>
1712
1713 * lib/jit_aarch64.c: Remove unused macros left from cut&paste
1714 of jit_arm.c.
1715
17162013-07-16 Paulo Andrade <pcpa@gnu.org>
1717
1718 * include/lightning/jit_aarch64.h, lib/jit_aarch64-cpu.c,
1719 lib/jit_aarch64-fpu.c, lib/jit_aarch64.c: New files
1720 implementing the new aarch64 port, as a new architecture,
1721 not as an expansion of the existing armv[4-7] port.
1722
1723 * check/lightning.c: Add aarch64 support and a small
1724 change to recognize character constants as immediate
1725 values.
1726
1727 * check/float.tst: Add aarch64 preprocessor conditionals
1728 to select proper expected value when converting [+-]Inf
1729 and NaN to integer.
1730
1731 * include/lightning/jit_arm.h, lib/jit_arm.c: Minor changes
1732 to better match the new aarch64 files.
1733
1734 * configure.ac, include/lightning.h,
1735 include/lightning/Makefile.am, include/lightning/jit_private.h,
1736 lib/Makefile.am, lib/lightning.c: Minor adjustments
1737 for the aarch64 port.
1738
17392013-07-08 Paulo Andrade <pcpa@gnu.org>
1740
1741 * NEWS, THANKS, configure.ac, doc/version.texi: Update for
1742 the 1.99a second alpha release.
1743
17442013-06-25 Paulo Andrade <pcpa@gnu.org>
1745
1746 * lib/jit_mips.c: Correct cut&paste error that caused wrong
1747 stack offset calculation for double arguments in stack in
1748 the o32 abi.
1749 Correct typo in the __LITTLE_ENDIAN macro name, that came
1750 from cut&paste error in the original typo in lib/jit_ppc.c.
1751
1752 * lib/jit_ia64.c, lib/jit_ppc.c: Correct typo in the
1753 __LITTLE_ENDIAN macro name.
1754
17552013-06-22 Paulo Andrade <pcpa@gnu.org>
1756
1757 * check/lightning.c, configure.ac, include/lightning.h,
1758 lib/lightning.c: Add tests and quirks to build/detect
1759 and/or work on Irix.
1760
1761 * include/lightning/jit_mips.h, lib/jit_mips-cpu.c,
1762 lib/jit_mips-fpu.c, lib/jit_mips.c: Adapt code to run
1763 in big endian mips, using the n32 abi.
1764
17652013-06-18 Paulo Andrade <pcpa@gnu.org>
1766
1767 * include/lightning.h: Minor extra preprocessor testing
1768 to "detect" byte order on x86 solaris, that now builds
1769 and pass all test cases.
1770
17712013-06-18 Paulo Andrade <pcpa@gnu.org>
1772
1773 * lib/jit_sparc-cpu.c: Correct compiler warning of value
1774 used before assignment. The usage is bogus as the api
1775 requires always patching jumps, but the random value used
1776 could cause an assertion due to invalid displacement.
1777
1778 * lib/jit_sparc.c: Always load and store double arguments
1779 in stack as 2 float loads or stores, for safety, as unaligned
1780 access is not allowed in Sparc Solaris.
1781
17822013-06-14 Paulo Andrade <pcpa@gnu.org>
1783
1784 * configure.ac: Force -mlp64 to CFLAGS on HP-UX ia64 port.
1785 It is the only supported mode, and expects gcc as C compiler.
1786
1787 * include/lightning.h, lib/jit_ia64-cpu.c, lib/jit_ia64.c:
1788 Correct ia64 port to work on HP-UX that runs it in big endian
1789 mode.
1790
17912013-06-10 Paulo Andrade <pcpa@gnu.org>
1792
1793 * lib/jit_hppa.c: Sanitize the cache synchronization inline
1794 assembly code that was doing twice the work and redundantly
1795 flushing the end address every loop iteration.
1796
17972013-06-09 Paulo Andrade <pcpa@gnu.org>
1798
1799 * configure.ac, check/Makefile.am, doc/Makefile.am: Do not
1800 explicitly link to -ldl, but instead autodetect the library
1801 with dlopen, dlsym, etc.
1802
1803 * check/lightning.c: Add workaround to apparently buggy
1804 getopt in HP-UX that sets optind to the wrong index, and
1805 use RTLD_NEXT on HP-UX instead of RTLD_DEFAULT to dlsym
1806 global symbols.
1807
1808 * include/lightning.h: Rework definitions of wordsize and
1809 byte order to detect proper values on HP-UX.
1810
1811 * lib/lightning.c: Minor correction to use MAP_ANONYMOUS
1812 instead of MAP_ANON on HP-UX.
1813
1814 * lib/jit_hppa.c: Float arguments must be passed on integer
1815 registers on HP-UX, not only for varargs functions.
1816 Add code to properly clear instruction cache. This was
1817 not required on Debian hppa port, but may have been working
1818 by accident.
1819
1820 * lib/jit_hppa-cpu.c: Follow pattern of HP-UX binaries and
1821 use bve,n instead of bv,n to return from functions.
1822
1823 * lib/jit_hppa-fpu.c: For some reason "fst? frX,rX,(rY)" did
1824 not work on the tested computer (HP-UX B.11.23 U 9000/785 HP-UX)
1825 so the code was changed, at first for __hpux only to add the
1826 base and offset register and use the instruction with an
1827 immediate (zero) offset.
1828
18292013-06-07 Paulo Andrade <pcpa@gnu.org>
1830
1831 * check/lightning.c, lib/jit_disasm.c, lib/jit_ppc-cpu.c,
1832 lib/jit_ppc-fpu.c, lib/jit_ppc.c, include/lightning.h,
1833 include/lightning/jit_ppc.h, include/lightning/jit_private.h:
1834 Adapt code to work on 32 bit AIX ppc using gcc. Most changes
1835 are basically to adapt the elf64 logic to 32 bit, as it does
1836 not use the same convention of 32 bit Darwin ppc.
1837
1838 * check/stack.tst: Add a fake memcpy function to the test
1839 case if running under AIX, as it is not available to dlsym.
1840
1841 * configure.ac: Check for getopt.h header, not available in
1842 AIX.
1843
18442013-06-01 Paulo Andrade <pcpa@gnu.org>
1845
1846 * include/lightning/jit_hppa.h, lib/jit_hppa-cpu.c,
1847 lib/jit_hppa-fpu.c, lib/jit_hppa.c: New files implementing
1848 the hppa port. Built on Debian Linux PA-RISC 2.0, 32 bit.
1849
1850 * check/float.tst: Add preprocessor for hppa expected
1851 values when converting NaN and +-Inf to an integer.
1852
1853 * check/ldst.inc: Ensure double load/store tests use an
1854 8 byte aligned address by default.
1855
1856 * lib/lightning.c: Correct a bug found during tests in
1857 the new port, where qmul* and qdiv* were not properly
1858 setting one of the result registers as modified in the
1859 function, what would be a problem if the only "write"
1860 usage were the qmul* or qdiv*.
1861
1862 * check/varargs.tst, check/varargs.ok: Add one extra
1863 interleaved integer/double test to validate proper code
1864 generation in the extra case.
1865
1866 * check/lightning.c, configure.ac, include/lightning.h,
1867 include/lightning/Makefile.am,
1868 include/lightning/jit_private.h, lib/Makefile.am,
1869 lib/jit_disasm.c: Update for the hppa port.
1870
18712013-04-27 Paulo Andrade <pcpa@gnu.org>
1872
1873 * check/varargs.tst: Correct misplaced .align directive
1874 that was causing the double buffer to not be aligned at
1875 8 bytes.
1876 * lib/jit_ia64-cpu.c:
1877 Properly implement abi for excess arguments passed on
1878 stack.
1879 Simplify load/store with immediate displacement argument
1880 with zero value.
1881 Simplify some calls to "subi" changing to "addi" with
1882 a negative argument.
1883 Remove some #if 0'ed code, that could be useful in
1884 special conditions, but the most useful one would be
1885 to "optimize" "static" jit functions, but for the sake
1886 of simplicity, jit functions are implemented in a way
1887 that can be passed back to C code as C function pointers.
1888 Add an attribute to prototypes of several unused functions.
1889 These functions are defined for the sake of implementing all
1890 Itanium documented instructions, but a significant amount of
1891 them is not used by lightning.
1892 * lib/jit_ia64-fpu.c: Simplify load/store with zero immediate
1893 displacement and add unused attribute for functions not used
1894 by lightning, but required to provide macros implementing all
1895 Itanium documented instructions.
1896 * lib/jit_ia64.c: Update for the properly implemented abi
1897 for stack arguments.
1898 * lib/lightning.c: Mark an unused function as such.
1899
19002013-04-27 Paulo Andrade <pcpa@gnu.org>
1901
1902 lib/jit_ia64-cpu.c:
1903 Correct immediate range check of integer comparisons when
1904 inverting arguments.
1905 Correct gei_u that was not decrementing immediate when
1906 inverting arguments.
1907 Correct b?add* and b?sub* that were not properly updating
1908 the result register.
1909
19102013-04-27 Paulo Andrade <pcpa@gnu.org>
1911
1912 * lib/jit_ia64-cpu.c: Correct wrong mapping of 2 instructions
1913 in "M-, stop, M-, stop" translation, that was ignoring the
1914 last stop (implemented as a nop I- stop).
1915
1916 * lib/jit_ia64-fpu.c: Properly implement fnorm.s and fnorm.d,
1917 as well as the proper integer to float or double conversion.
1918
19192013-04-27 Paulo Andrade <pcpa@gnu.org>
1920
1921 * lib/jit_ia64-cpu.c: Correct bogus implementation of ldr_T
1922 for signed integers, that was using ld1.s, ld2.s and ld4.s.
1923 The ".s" stands for speculative load, not sign extend.
1924
1925 * lib/jit_ia64-fpu.c: Correct bogus implementation of ldxr_T
1926 for float and double. The third (actually, second) argument
1927 is indeed added to the base register, but the base register
1928 is modified. The actual M7 implementation was already correct,
1929 just the ldxr_f and ldxr_d implementation that was kept in
1930 a prototype state, misinterpreting what M7 does.
1931
19322013-04-27 Paulo Andrade <pcpa@gnu.org>
1933
1934 * lib/jit_ia64-cpu.c: Correct X2 pattern matching by preventing
1935 it to attempt to require a stop between the L and the X
1936 instruction; that is, check the registers and predicates
1937 before emitting the L instruction, not after.
1938
1939 * lib/jit_ia64-fpu.c: Slightly simplify and correct
1940 divr_f and divrd_d implementation.
1941
1942 * check/lightning.c: Add __ia64__ preprocessor define
519a9ea1 1943 on Itanium.
4a71579b
PC
1944
1945 * check/alu.inc, check/clobber.tst, check/float.tst: Define
1946 several macros conditionally to __ia64__. This is required
1947 because __ia64__ jit generation can use way too many memory,
1948 due to not implementing instruction reordering to avoid
1949 as much as possible "stops", what causes way too many nops
1950 to be generated, as well as the fact that division and
1951 remainder requires function calls, and float division
1952 requires significant code to implement.
1953
19542013-04-27 Paulo Andrade <pcpa@gnu.org>
1955
1956 * include/lightning.h: Add new backend specific movr_w_d,
1957 movr_d_w and movi_d_w codes as helpers to ia64 varargs
1958 functions arguments.
1959
1960 * lib/jit_ia64-cpu.c:
1961 Correct wrong encoding of A5 small integers.
1962 Correct define of "mux" instruction modifiers.
1963 Correct ordering of arguments and predicates of cmp_xy
1964 implementation with immediate arguments; like most other
1965 codes with an immediate, the immediate is the second, not
1966 the third argument.
1967
1968 * lib/jit_ia64-fpu.c: Actual implementation of the code
1969 to move to/from gpr to/from fpr, to implement varargs abi.
1970
1971 * lib/jit_ia64.c: Make fpr argument registers not allocatable
1972 as temporaries, no need for the extra checks when there are
1973 plenty registers.
1974
1975 * lib/jit_print.c, lib/lightning.c: Minor updates for the
1976 new movr_w_d, movr_d_w and movi_d_w codes.
1977
19782013-04-26 Paulo Andrade <pcpa@gnu.org>
1979
1980 * lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c: Correct code to
1981 also insert a stop to break an instruction group if a
1982 register is written more than once in the same group.
1983 This may happen if a register is argument and result of
1984 some lightning call (not a real instruction). The most
1985 common case should be code in the pattern:
1986 movl rn=largenum
1987 ...
1988 mov rn=smallnum
1989 where "rn" would end up holding "largenum".
1990 But the problem possibly could happen in other circumstances.
1991
19922013-04-26 Paulo Andrade <pcpa@gnu.org>
1993
1994 * include/lightning/jit_ia64.h, lib/jit_ia64-cpu.c,
1995 lib/jit_ia64-fpu.c, lib/jit_ia64.c:
1996 Relocate JIT_Rn registers to the local registers, as, like
1997 float registers, div/rem and sqrt are implemented as function
1998 calls, and may overwrite non saved scratch registers.
1999 Change patch_at to receive a jit_code_t instead of a
2000 jit_node_t, so that it is easier to "inline" patches when
2001 some instruction requires complex code to implement, e.g.
2002 uneq and ltgt.
2003 Correct arguments to FMA and FMA like instructions that,
2004 due to a cut&paste error were passing the wrong argument
2005 to the related F- implementation function.
2006 Rewrite ltgt to return the proper result if one (or both)
2007 of the arguments is unordered.
2008
20092013-04-26 Paulo Andrade <pcpa@gnu.org>
2010
2011 * include/lightning/jit_ia64.h, include/lightning/jit_private.h,
2012 lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c, lib/jit_ia64.c,
2013 lib/lightning.c: Rework code to detect need of a "stop" to
2014 also handle predicates, as if a predicate is written, it
2015 cannot be read in the same instruction group.
2016 Use a single jit_regset_t variable for all registers when
2017 checking need for a stop (increment value by 128 for
2018 float registers).
2019 Correct wrong "subi" implementation, as the code executed
2020 is r0=im-r1, not r0=r1-im.
2021 Use standard lightning 6 fpr registers, and rework to
2022 use callee save float registers, that may be spill/reloaded
2023 in prolog/epilog. This is required because some jit
2024 instructions implementations need to call functions; currently
2025 integer div/mod and float sqrt, what may change the value of
2026 scratch float registers.
2027 Rework point of "sync" of branches that need to return a
2028 patch'able address, because the need for a "stop" before a
2029 predicate read causes all branches to be the instruction
2030 in slot 0, as there is no template to "stop" and branch
2031 in the same instruction "bundle".
2032
20332013-04-25 Paulo Andrade <pcpa@gnu.org>
2034
2035 * include/lightning/jit_ia64.h, lib/jit_ia64-cpu.c,
2036 lib/jit_ia64-fpu.c, lib/jit_ia64.c: New files implementing
2037 the basic infrastructure of an Itanium port. The code
2038 compiles and can generate jit for basic hello world like
2039 functions.
2040
2041 * check/lightning.c, configure.ac, include/lightning.h,
2042 include/lightning/Makefile.am, include/lightning/jit_private.h,
2043 lib/Makefile.am, lib/lightning.c: Update for the Itanium
2044 port.
2045
2046 * lib/jit_mips-cpu.c, lib/jit_mips.c: Correct typo and
2047 make the jit_carry register local to the jit_state_t.
2048 This matches code reviewed in the Itanium port, that
2049 should use the same base logic to handle carry/borrow.
2050
20512013-04-10 Paulo Andrade <pcpa@gnu.org>
2052
2053 * include/lightning/jit_private.h, lib/jit_arm.c,
2054 lib/jit_mips-cpu.c, lib/jit_mips.c, lib/jit_ppc-cpu.c,
2055 lib/jit_ppc.c, lib/jit_print.c, lib/jit_sparc-cpu.c,
2056 lib/jit_sparc.c, lib/jit_x86-cpu.c, lib/jit_x86.c,
2057 lib/lightning.c: Change all jit_regset macros to take
2058 a pointer argument, to avoid structure copies when
2059 adding a port to an architecture with more than 64
2060 registers.
2061
20622013-04-08 Paulo Andrade <pcpa@gnu.org>
2063
2064 * lib/jit_arm.c, lib/jit_ppc.c: Do not rely on __clear_cache
2065 aligning to the next page boundary the end argument. It may
2066 actually truncate it.
2067
20682013-03-29 Paulo Andrade <pcpa@gnu.org>
2069
2070 * include/lightning/jit_private.h, lib/jit_arm.c, lib/jit_memory.c,
2071 lib/jit_mips.c, lib/jit_ppc.c, lib/jit_sparc.c, lib/jit_x86.c,
2072 lib/lightning.c: Do not start over jit generation if can grow
2073 the code buffer with mremap without moving the base pointer.
2074
20752013-03-29 Paulo Andrade <pcpa@gnu.org>
2076
2077 * lib/jit_memory.c: Implement a simple memory allocation wrapper
2078 to allow overriding calls to malloc/calloc/realloc/free, as well
2079 as ensuring all memory containing pointers is zero or points to
2080 allocated memory.
2081
2082 * include/lightning.h, include/lightning/jit_private.h: Definitions
2083 for the memory allocation wrapper.
2084
2085 * lib/Makefile.am: Update for new jit_memory.c file.
2086
2087 * lib/jit_arm.c, lib/jit_disasm.c, lib/jit_mips.c, lib/jit_note.c,
2088 lib/jit_ppc.c, lib/jit_sparc.c, lib/jit_x86.c, lib/lightning.c:
2089 Use the new memory allocation wrapper code.
2090
20912013-03-22 Paulo Andrade <pcpa@gnu.org>
2092
2093 * configure.ac, include/lightning/jit_private.h, lib/lightning.c:
2094 Remove dependency on gmp. Only a simple bitmap was required, and
2095 that was not enough reason to force linking to gmp and possible
2096 complications caused by it.
2097
20982013-03-10 Paulo Andrade <pcpa@gnu.org>
2099
2100 * include/lightning.h: Add check for __powerpc__ defined
2101 in Linux, while Darwin defines __ppc__.
2102
2103 * include/lightning/jit_ppc.h: Adjust register definitions
2104 for Darwin 32 bit and Linux 64 bit ppc usage and/or ABI.
2105
2106 * include/lightning/jit_private.h: Add proper check for
2107 Linux __powerpc__ and an data definition for an workaround
2108 to properly handle code that starts with a jump to a "main"
2109 label.
2110
2111 * lib/jit_disasm.c: Add extra disassembler initialization
2112 for __powerpc64__.
2113
2114 * lib/jit_ppc-cpu.c: Add extra macros and functions, and
2115 correct/adapt previous ones to handle powerpc64.
2116
2117 * lib/jit_ppc-fpu.c: Adapt for 64 bit wordsize. Basically
2118 add conversion from/to int32/int64 and proper handling of
2119 load/store offsets too large for 32 bit.
2120
2121 * lib/jit_ppc.c: Add calls to 64 bit codes and adaptation
2122 for the PowerPC 64 bit Linux ABI.
2123
2124 * lib/jit_arm.c, lib/jit_mips.c, lib/jit_sparc, lib/jit_x86.c,
2125 lib/lightning.c: Correct off by one error when restarting jit
2126 of a function due to finding too late that needs to spill/reload
2127 some register. Problem was found by accident on a very special
2128 condition during PowerPC 64 code adaptation.
2129
21302013-03-08 Paulo Andrade <pcpa@gnu.org>
2131
2132 * check/lightning.c: Add missing ppc preprocessor definition.
2133
21342013-03-06 Paulo Andrade <pcpa@gnu.org>
2135
2136 * check/float.tst: Comment out the int to negative infinity
2137 test in mips for the moment because not all Loongson agrees
2138 on the result.
2139
2140 * lib/jit_disasm.c: Add a test instead of an assertion
2141 when loading symbols for disassembly due to a failure with
2142 a simple binutils build in Debian mipsel64.
2143
21442013-03-06 Paulo Andrade <pcpa@gnu.org>
2145
2146 * include/lightning/jit_private.h, lib/jit_arm-cpu.c,
2147 lib/jit_arm.c, lib/jit_disasm.c, lib/jit_mips-cpu.c,
2148 lib/jit_mips.c, lib/jit_note.c, lib/jit_ppc-cpu.c,
2149 lib/jit_ppc.c, lib/jit_print.c, lib/jit_sparc-cpu.c,
2150 lib/jit_sparc.c, lib/jit_x86-cpu.c, lib/jit_x86.c,
2151 lib/lightning.c: Add an extra structure for data storage
2152 during jit generation, and release it after generating
2153 jit, to reduce a bit memory usage, and also to make it
2154 easier to understand what data is available during
2155 jit runtime.
2156
21572013-03-06 Paulo Andrade <pcpa@gnu.org>
2158
2159 * lib/lightning.c: Make data and code buffer readonly.
2160
21612013-02-20 Paulo Andrade <pcpa@gnu.org>
2162
2163 * doc/body.texi: Fool proof validate the examples of what
2164 an assembly-language programmer would write and correct the
2165 wrong sparc example.
2166
21672013-02-19 Paulo Andrade <pcpa@gnu.org>
2168
2169 * doc/body.texi: Add back the SPARC code generation example.
2170
21712013-02-19 Paulo Andrade <pcpa@gnu.org>
2172
2173 * check/lightning.c: Remove state flag to work with partial
2174 sparc port, by just disassembling if there was incomplete
2175 code generation.
2176
2177 * jit_sparc-cpu.c: Correct wrong range check for immediate
2178 integer constants (off by one bit shift).
2179 Correct macro implementing equivalent "rd %y, rd" assembly.
2180 Implement qmul* and qdiv*.
2181
2182 * jit_sparc.c: Update for qmul* and qdiv* and remove logic
2183 to handle incomplete code generation during sparc port.
2184
21852013-02-18 Paulo Andrade <pcpa@gnu.org>
2186
2187 * check/float.tst: Add sparc to list of known NaN and +-Inf
2188 to integer conversion.
2189
2190 * check/lightning.c: Define __sparc__ to preprocessor in
2191 the sparc backend.
2192
2193 * include/lightning/jit_private.h: Correct wrong definition
2194 of emit_stxi_d, that has lived for a long time, but would
2195 cause problems whenever needing to spill/reload a float
2196 register.
2197
2198 * include/lightning/jit_sparc.h: Can only use %g2,%g3,%g4
2199 for scratch variables, as other "global" registers are
2200 reserved for the system, e.g. libc.
2201 Reorder float register naming to make it easier to
2202 access odd float registers, so that generating code for
2203 pusharg and getarg is easier for the IR.
2204
2205 * lib/jit_mips-cpu.c, lib/jit_ppc-cpu.c: Update to match
2206 new code in jit_sparc-cpu.c. It must call jit_get_reg
2207 with jit_class_nospill if using the register to move
2208 an unconditional branch address to it, as the reload
2209 will not happen (actually could happen in the delay
2210 slot...)
2211
2212 * lib/jit_sparc-cpu.c: Correct wrong macro definition for
2213 ldxr_s.
2214 Properly implement div* and implement rem. Div* needs
2215 to use the y register, and rem* needs to be synthesized.
2216 Correct b?sub* macro definitions.
2217
2218 * lib/jit_sparc-fpu.c: Correct reversed float to/from double
2219 conversion.
2220 Correct wrong jit_get_reg call asking for a gpr and then
2221 using the fpr with that number.
2222 Correct wrong branch displacement computation for
2223 conditional branches.
2224
2225 * lib/jit_sparc.c: Correct getarg_d and pushargi_d implementation.
2226 Add rem* entries to the switch converting IR to machine code.
2227
2228 * lib/lightning.c: Correct a problem detected when adding
2229 the jit_class_nospill flag to jit_get_reg, that was caused
2230 when having a branch to an "epilog" node, what would cause
2231 the code to think all registers in unknown state were live,
2232 while in truth, all registers in unknown state in the
2233 "just after return" point are actually dead.
2234
22352013-02-17 Paulo Andrade <pcpa@gnu.org>
2236
2237 * include/lightning/jit_sparc.h, lib/jit_sparc-cpu.c,
2238 lib/jit_sparc-fpu.c, lib/jit_sparc.c: New files implementing
2239 the basic framework of the sparc port.
2240
2241 * configure.ac, include/lightning.h, include/lightning/Makefile.am,
2242 include/lightning/jit_private.h, lib/jit_disasm.c: Update
2243 for the sparc port framework.
2244
2245 * lib/jit_mips.c: Correct reversed retr/reti logic.
2246
2247 * lib/jit_ppc.c: Correct misspelled __LITTLE_ENDIAN.
2248
2249 * lib/lightning.c: Always do byte hashing in hash_data, because
2250 the logic to "compress" strings causes large pointers to not
2251 be guaranteed aligned at 4 byte boundaries.
2252 Update for the sparc port framework.
2253
22542013-02-11 Paulo Andrade <pcpa@gnu.org>
2255
2256 * lib/jit_arm.c: Correct jit_pushargi_f in the arm hardfp abi.
2257 Most of the logic uses even numbered register numbers, so that
2258 a float and a double can be used in the same register, but
2259 the abi requires packing the float arguments, so jit_pushargi_f
2260 needs to allocate a temporary register to modify only the
2261 proper register argument (or be very smart to push two
2262 immediate arguments if applicable).
2263
22642013-02-11 Paulo Andrade <pcpa@gnu.org>
2265
2266 * include/lightning.h, lib/lightning.c: Implement the new
2267 jit_clear_state and jit_destroy_state calls. jit_clear_state
2268 releases all memory not required during jit_execution; that
2269 is, leaves only the mmap'ed data and code buffers allocated.
2270 jit_destroy_state releases the mmap'ed buffers as well as
2271 the jit_state_t object itself, that holds pointers to the
2272 code and data buffers, as well as annotation pointers (for
2273 disassembly or backtrace) in the data buffer.
2274
2275 * lib/jit_note.c: Correct invalid vector offset access.
2276
2277 * check/ccall.c, check/lightning.c, doc/ifib.c, doc/incr.c,
2278 doc/printf.c, doc/rfib.c, doc/rpn.c: Use the new jit_clear_state
2279 and jit_destroy_state calls, to demonstrate the new code to
2280 release all jit memory.
2281
2282 * doc/body.texi: Add basic documentation and usage description
2283 of jit_clear_state and jit_destroy_state.
2284
22852013-02-11 Paulo Andrade <pcpa@gnu.org>
2286
2287 * include/lightning/jit_private.h, lib/jit_note.c, lib/lightning.c:
2288 Store all annotation information in the mmap'ed area reserved for
2289 read only data. This adds code to not allocate memory for jit_note_t
2290 objects, and to relocate jit_line_t objects and its contents after
2291 calculating annotation information. The jit_line_t objects are
2292 relocated because it is not possible to always calculate before
2293 hand data layout because note information may be extended or
2294 redundant entries removed, as well as allowed to be added in
2295 non sequential order.
2296 A bug was also corrected in _jit_set_note, that was causing it
2297 to allocate new jit_line_t objects when not needed. It was still
2298 working correctly, but allocating way more memory than required.
2299
23002013-02-05 Paulo Andrade <pcpa@gnu.org>
2301
2302 *include/lightning.h, lib/lightning.c: Add the new jit_live code
2303 to explicitly mark a register as live. It is required to avoid
2304 assuming functions always return a value in the gpr and fpr return
2305 register, and to avoid the need of some very specialized codes
2306 that vary too much from backend to backend, to instruct the
2307 optimization code the return register is live.
2308
2309 * lib/jit_arm.c, lib/jit_mips.c, lib/jit_ppc.c, lib/jit_print.c,
2310 lib/jit_x86.c: Update for the new jit_live code.
2311
2312 * check/ret.ok, check/ret.tst: New files implementing a simple
2313 test case that would previously fail at least in ix86/x86_64.
2314
2315 * check/Makefile.am: Update for new "ret" test case.
2316
23172013-02-05 Paulo Andrade <pcpa@gnu.org>
2318
2319 * lib/jit_ppc-cpu.c, lib/jit_ppc.c: Validate and correct
2320 problems in the qmul and qdiv ppc implementation.
2321
23222013-02-04 Paulo Andrade <pcpa@gnu.org>
2323
2324 * include/lightning.h, include/lightning/jit_private.h,
2325 lib/jit_arm-cpu.c, lib/jit_arm.c, lib/jit_mips-cpu.c,
2326 lib/jit_mips.c, lib/jit_ppc-cpu.c, lib/jit_ppc.c,
2327 lib/jit_x86-cpu.c, lib/jit_x86.c, lib/lightning.c:
2328 Implement the new qmul and qdiv instructions that return signed
2329 and unsigned lo/hi multiplication result and div/rem division result.
2330 These should be useful for jit translation of code that needs to
2331 know if a multiplication overflows (no branch opcode added) or if
2332 a division is exact (easy check if remainder is zero).
2333
2334 * check/lightning.c, lib/jit_print.c, check/Makefile.am,
2335 check/all.tst: Update for the new qmul and qdiv instructions.
2336
2337 * check/qalu.inc, check/qalu_div.ok, check/qalu_div.tst,
2338 check/qalu_mul.ok, check/qalu_mul.tst: New files implementing
2339 simple test cases for qmul and qdiv.
2340
23412013-01-30 Paulo Andrade <pcpa@gnu.org>
2342
2343 * doc/body.texi: Correct "jmpi" description that incorrectly
2344 told it was possible to pass any address as jump target. The
2345 only way to do that is "movi+jmpr".
2346
23472013-01-30 Paulo Andrade <pcpa@gnu.org>
2348
2349 * lib/jit_x86-cpu.c: Correct undefined behavior code.
2350 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56143
2351
23522013-01-29 Paulo Andrade <pcpa@gnu.org>
2353
2354 * configure.ac: Use AC_CONFIG_HEADERS instead of AC_CONFIG_HEADER
2355 to have HAVE_CONFIG_H defined with latest aclocal.
2356
2357 * include/lightning/jit_private.h, lib/lightning.c: Add new
2358 abstraction to use an heuristic to calculate amount of space
2359 required for jit generation, and code to reallocate buffer if
2360 did miscalculate it.
2361
2362 * lib/jit_arm.c, lib/jit_mips.c, lib/jit_ppc.c, lib/jit_x86.c:
2363 Update to use new code to estimate and resize of required buffer
2364 for jit code.
2365
2366 * lib/jit_x86-cpu.c: Minor cosmetic change to avoid adding a
2367 non required rex prefix when calling a function pointer stored
2368 in a register.
2369
23702013-01-24 Paulo Andrade <pcpa@gnu.org>
2371
2372 * check/Makefile.am: "make debug" target should pass only
2373 the main test tool program as argument for running gdb
2374
2375 * configure.ac: Add the --enable-assertions options.
2376
2377 * doc/Makefile.am, doc/body.texi, doc/lightning.texi:
2378 Major rewrite of the documentation to match the current
2379 implementation.
2380
2381 * doc/version.texi: Automatic date update.
2382
2383 * doc/ifib.c, doc/incr.c, doc/printf.c, doc/rfib.c, doc/rpn.c:
2384 Implementation of the documentation examples, that are also
2385 compiled during a normal build.
2386
2387 * doc/p-lightning.texi, doc/porting.texi, doc/toc.texi,
2388 doc/u-lightning.texi, doc/using.texi: These files were
2389 renamed in the documentation rewrite, as the documentation
2390 was significantly trimmed due to full removal of the porting
2391 chapters. Better porting documentation should be added but
2392 for the moment it was just removed the documentation not
2393 matching the implementation.
2394
23952013-01-18 Paulo Andrade <pcpa@gnu.org>
2396
2397 * lib/jit_note.c: Correct bounds check and wrong code keeping
2398 a pointer that could be changed after a realloc call.
2399
24002013-01-18 Paulo Andrade <pcpa@gnu.org>
2401
2402 * check/3to2.tst, check/add.tst, check/allocai.tst, check/bp.tst,

2409 lib/jit_mips.c, lib/jit_note.c, lib/jit_ppc.c, lib/jit_print.c,
2410 lib/jit_x86.c, lib/lightning.c: Extend the "jit_note" abstraction
2411 with the new "jit_name" call, that receives a string argument, and
2412 should usually be called to mark boundaries of functions of code
2413 generating jit (that is, it is not expected that the language
2414 generating jit map its functions to jit functions).
2415
24162013-01-17 Paulo Andrade <pcpa@gnu.org>
2417
2418 * check/add.tst, check/allocai.tst, check/bp.tst, check/divi.tst,
2419 check/fib.tst, check/lightning.c, include/lightning/jit_arm.h,
2420 include/lightning/jit_mips.h, include/lightning/jit_ppc.h,
2421 include/lightning/jit_private.h, include/lightning/jit_x86.h:
2422 Make JIT_RET, JIT_FRET and JIT_SP private. These should not be
2423 used in any operations due to frequently having special
2424 constraints (usually JIT_FRET). JIT_FP must be made available
2425 because it must be used as the base register to access stack
2426 space allocated with jit_allocai.
2427
24282013-01-14 Paulo Andrade <pcpa@gnu.org>
2429
2430 * include/lightning.h, lib/lightning.c: Add an extra align
2431 argument to the jit_data call (that should be made private),
2432 so that it should not align strings at 8 bytes.
2433 Correct the jit_note call to include the null ending byte
2434 when adding label/note names to the "jit data section".
2435
24362013-01-11 Paulo Andrade <pcpa@gnu.org>
2437
2438 * lib/jit_note.c: New file implementing a simple string+integer
2439 annotation, that should be used to map filename and line number
2440 to offsets in the generated jit.
2441
2442 * include/lightning.h, lib/lightning.c: Update for the new
2443 note code.
2444 Add an extra mandatory argument to init_jit, that is used
2445 as argument to bfd_openr.
2446 Change from generic void* to char* the argument to jit_note
2447 and add an extra integer argument, to map to filename and
2448 line number.
2449
2450 * check/ccall.c, check/lightning.c, include/lightning/jit_private.h,
2451 lib/jit_arm.c, lib/jit_disasm.c, lib/jit_mips.c, lib/jit_ppc.c,
2452 lib/jit_print.c, lib/jit_x86.c: lib/Makefile.am: Update for the
2453 new annotation code.
2454
2455 * configure.ac, check/Makefile.am: Update to work with latest
2456 automake.
2457
24582013-01-09 Paulo Andrade <pcpa@gnu.org>
2459
2460 * include/lightning.h, lib/jit_arm.c, jit_mips-fpu.c,
2461 lib/jit_mips.c, lib/jit_print.c, lib/jit_x86.c, lib/lightning.c:
2462 Remove the jit_code_getarg_{f,d} and jit_code_pusharg{i,r}_{f,d}
2463 calls, replacing them with the new, internal only, jit_movr_w_f,
2464 jit_mov{r,i}_f_w, jit_movr_ww_d, and jit_mov{i,r}_d_ww, that
2465 better describe the operation being done, and allow removing
2466 the hackish code to detect special conditions for arm when
2467 moving from/to vfp from/to a grp register pair.
2468 Rename jit_code_retval_{f,d} to jit_code_x86_retval_{f,d} as
2469 it is specific to 32 bit x86, and used to move abi return
2470 value in x87 register to a sse register.
2471
24722013-01-05 Paulo Andrade <pcpa@gnu.org>
2473
2474 * check/cccall.c, check/ccall.ok: New test case to validate
2475 interleaved calls from/to C code and jit.
2476
2477 * check/Makefile.am: Update for the new ccall test case.
2478
2479 * include/lightning.h, lib/lightning.c: Add the new jit_address
2480 call that returns the real/final address of a "note" in the
2481 generated jit. It requires a jit_node_t as returned by the
2482 jit_note call, and is only valid after calling jit_emit.
2483 Add an intermediate solution to properly handle arm
2484 soft and softfp modes that move a double to an integer register
2485 pair. Currently it just adds extra tests for the condition,
2486 but the proper solution should be to have extra lightning
2487 codes for these conditions, codes which should be only used
2488 by the backends that need it, and merged with the existing
2489 jit_pusharg*_{f,d}.
2490
2491 * include/lightning/jit_private.h: Add new jit_state_t flag
2492 to know it finished jit_emit, so that calls to jit_address
2493 are valid.
2494
2495 * lib/jit_mips.c: Correct abi implementation so that the
2496 new ccall test case pass. Major problem was using
2497 _jit->function.self.arg{i,f} as boolean values, but that
2498 would cause lightning.c:patch_registers() to incorrectly
2499 assume only one register was used as argument when calling
2500 jit_regarg_p(); _jit->function.self.arg{i,f} must be the
2501 number of registers used as arguments (in all backends).
2502
2503 * lib/jit_x86.c: Add workaround, by marking %rax as used,
2504 to a special condition, when running out of registers and the
2505 allocator trying to spill and reload %rax, but %rax was used
2506 as a pointer to a function, what would cause the reload to
2507 destroy the return value. This condition can be better
2508 generalized, but the current solution is good enough.
2509
2510 * include/lightning/jit_ppc.h, lib/jit_ppc-cpu.c, lib/jit_ppc.c:
2511 Rewrite logic to handle arguments, as the original code was
2512 written based on a SysV pdf about the generic powerpc ABI,
2513 what did "invent" a new abi for the previous test cases, but
2514 failed in the new ccall test in Darwin PPC. Now it properly
2515 handles 13 float registers for arguments, as well as proper
2516 computation of stack offsets when running out of registers
2517 for arguments.
2518
25192013-01-02 Paulo Andrade <pcpa@gnu.org>
2520
2521 * check/float.tst: Correct test case to match ppc also
2522 converting positive infinity to 0x7fffffff.
2523
2524 * lib/jit_arm-swf.c: Correct typos with double underscores.
2525
2526 * lib/lightning.c: Correct remaining wrong reverse jump logic.
2527
25282012-12-29 Paulo Andrade <pcpa@gnu.org>
2529
2530 * lib/lightning.c: Correct both, wrong and confusing logic
2531 to compute the reverse of a jump. Now it properly matches
2532 C semantics for "eq" (==) and "ne" (!=) and correct computation
2533 of reverse of "uneq" as "gt".
2534
2535 * check/branch.tst: Update "ne" float branch check that
2536 previously happened to be wrongly tested with a NaN argument.
2537
25382012-12-29 Paulo Andrade <pcpa@gnu.org>
2539
2540 * check/float.ok, check/float.tst: New test cases implementing
2541 extensive validation of float comparison and branch code
2542 generation as well as integer conversion, involving NaN and
2543 [+-]Inf.
2544
2545 * lib/jit_arm-swf.c, lib/jit_x86-sse.c, lib/jit_x86-x87.c:
2546 Correct bugs found by new float test case.
2547
2548 * lib/jit_x86.c: Correct cut&paste error added in commit to
2549 convert jit_arg* return value to a jit_node_t*, that would
2550 cause it to not properly handle double arguments in ix86.
2551
2552 * check/Makefile.am: Update for the new test case.

25542012-12-28 Paulo Andrade <pcpa@gnu.org>

2557 lib/jit_mips.c, lib/jit_ppc.c, lib/jit_print.c, lib/jit_x86.c,
2558 lib/lightning.c: Change return value of jit_arg{,_f,_d} to
2559 a jit_node_t* object, that should be used as argument to
2560 jit_getarg_{c,uc,s,us,i,ui,l,f,d}. This just requires changing
2561 from jit_int32_t to jit_pointer_t (or jit_node_t*) the "handle"
2562 for the getarg calls, with the benefit that it makes it easy
2563 to implement patching of the stack address of non register
2564 arguments, this way allowing to implement variable size stack
2565 frames if applicable; useful if there are too many registers and
2566 jit functions uses only a few callee save registers.
2567
25682012-12-27 Paulo Andrade <pcpa@gnu.org>
2569
2570 * lib/jit_arm.c, lib/jit_mips-cpu.c, lib/jit_mips.c: Correct
2571 regressions when patching jit_calli for a forward function.
2572
2573 * lib/jit_ppc-cpu.c: Correct wrong arguments to ANDI opcode
2574 in jit_getarg_u{c,s} implementation.
2575
25762012-12-23 Paulo Andrade <pcpa@gnu.org>
2577
2578 * check/call.ok, check/call.tst: New test cases to validate
2579 simple typed argument and return values in function calls.
2580
2581 * check/lightning.c: Properly handle jit_movi of labels for
2582 backward and forward code labels.
2583
2584 * check/Makefile.am: Update for new test case.
2585
25862012-12-23 Paulo Andrade <pcpa@gnu.org>
2587
2588 * check/carry.ok, check/carry.tst: New test case to validate
2589 carry condition handling.
2590
2591 * check/Makefile.am: Update for new test case.
2592
25932012-12-22 Paulo Andrade <pcpa@gnu.org>
2594
2595 * lib/jit_ppc-cpu.c, lib/jit_ppc.c: Implement logic for
2596 jit_htonr for big endian, so that ppc (big endian) pass the
2597 new clobber.tst test case.
2598
25992012-12-22 Paulo Andrade <pcpa@gnu.org>
2600
2601 * lib/jit_arm.c: Correct use of wrong argument offset
2602 variable in armv7l or float/double argument for varargs
2603 function in armv7hl.
2604 Correct jit_getarg* logic in software float mode to
2605 match expected behavior in other backends, that is, if
2606 a function is not called, it is safe to use a few lightning
2607 calls before a next jit_getarg* call, as done in the test
2608 case check/stack.tst. The proper solution should be to
2609 extend the parser in lib/lightning.c to check if there is
2610 some float operation that will call some (libgcc?) function,
2611 but software float arm should be a very uncommon backend for
2612 lightning, so, just load the already in place arguments
2613 saved to stack, assuming the register argument was clobbered
2614 (what should not be the case most times...).
2615
26162012-12-22 Paulo Andrade <pcpa@gnu.org>
2617
2618 * check/clobber.ok, check/clobber.tst: New test case doing
2619 extensive validation tests to ensure registers not used in
2620 a operation are not clobbered.
2621
2622 * check/Makefile.am: Update for new test case.
2623
26242012-12-21 Paulo Andrade <pcpa@gnu.org>
2625
2626 * lib/lightning.c: Partially rewrite/revert code to compute
2627 initial register live state at the start of a basic block.
2628 The original logic was corrupted when adding optimizations
2629 to do as few computations as possible in jit_update. The
2630 reglive field must be always a known set of live registers
2631 at the start of a basic block. The value that was incorrect
2632 was the regmask field, that must be the set of registers
2633 that are in unknown state, because they are not known live,
2634 neither set (or possibly not set) in the basic block, and
2635 *must* store the state at the start of the basic block.
2636
26372012-12-20 Paulo Andrade <pcpa@gnu.org>
2638
2639 * include/lightning/jit_ppc.h: Correct mismatch of JIT_F{1,5}
2640 with enum codes, that were correct, and returned by jit_f().
2641
2642 * lib/jit_ppc-cpu.c, lib/jit_ppc-fpu.c, lib/jit_ppc.c: Properly
2643 implement and better describe values when generating stack
2644 frames.
2645
26462012-12-18 Paulo Andrade <pcpa@gnu.org>
2647
2648 * check/stack.ok, check/stack.tst: New files to test data
2649 integrity on a deep chain of stack frames.
2650
2651 * lib/jit_arm.c, lib/jit_arm-cpu.c, lib/jit_mips.c,
2652 lib/jit_mips-cpu.c, lib/jit_ppc.c, lib/jit_ppc-cpu.c,
2653 lib/jit_x86.c, lib/jit_x86-cpu.c: Calculate _jit->function->stack
2654 in the emit stage, otherwise it will calculate it wrong if
2655 need to jit_allocai space to spill registers.
2656
2657 * lib/lightning.c: Correct wrong offset when updating the
2658 "current" jit function pointer in the code that may need to
2659 allocate stack space to spill registers.
2660
2661 * check/lightning.c: Correct off by one data space check.
2662
2663 * check/Makefile.am: Update for new test case.
2664
26652012-12-17 Paulo Andrade <pcpa@gnu.org>
2666
2667 * check/fop_abs.ok, check/fop_abs.tst, check/fop_sqrt.ok,
2668 check/fop_sqrt.tst: New files implementing simple test cases
2669 for the extra float operations.
2670
2671 * check/Makefile.am: Update for new test cases.
2672
2673 * check/alu.inc: Add an extra macro to check for unordered
2674 equality on tests where it is expected to use NaN as an
2675 argument.
2676
2677 * check/lightning.c: Minor change for proper/common argument
2678 syntax handling ommiting arguments to options.
2679
26802012-12-17 Paulo Andrade <pcpa@gnu.org>
2681
2682 * check/Makefile.am: Automatically generate pattern list
2683 of tests with alternate jit generation options. This should
2684 prevent typos and needing to change multiple places after
2685 a change.
2686
26872012-12-14 Paulo Andrade <pcpa@gnu.org>
2688
2689 * check/lightning.c: Remove the ".cpu name value" syntax,
2690 as it was not able to do proper changes before the jit
2691 internal data structure was initialized. Now it supports
2692 several getopt options to force using different jit
2693 generation options, effectively replacing the previous
2694 syntax.
2695
2696 * check/run-test: Add simple extra logic to handle differently
2697 named test scripts, used to test things like x87 coprocessor
2698 in ix86, and arm instruction set or software float in armv7l.
2699
2700 * configure.ac: Add some AC_RUN_IFELSE calls to figure at
2701 compile time if can test different code generation options,
2702 and update Makefile generation accordingly.
2703
2704 * check/Makefile.am, lib/jit_arm.c, lib/jit_x86.c: Update to
2705 properly work with the test tool updating the jit_cpu global
2706 information.
2707
2708 * check/check.arm.sh, check/check.swf.sh, check/check.x87.sh:
2709 New wrapper files passing -mthumb=0, mvfp=0 and -mx87=1 to
2710 the test tool, if applicable, so that it can validate alternate
2711 code generation options on test hosts that support them.
2712
27132012-12-14 Paulo Andrade <pcpa@gnu.org>
2714
2715 * lib/jit_x86-x87.c, lib/jit_x86.c: Correct test cases in ix86
2716 when using the x87 coprocessor instead of sse2+.
2717
27182012-12-14 Paulo Andrade <pcpa@gnu.org>
2719
2720 * include/lightning.h, include/lightning/jit_private.h,
2721 lib/jit_arm.c, lib/jit_mips.c, lib/jit_ppc.c, lib/jit_x86.c,
2722 lib/lightning.c: Make jit_ellipsis implementation not
2723 backend specific. It is not intended to handle va_list
2724 like objects at runtime, as jit_arg* and jit_getarg*
2725 return constant values resolved at parse time, so, effectively
2726 it is not possible to create printf like jit functions, as
2727 there is no va_start, va_arg, va_end, etc, abstraction. This
2728 limitation should be kept for the sake of making new ports
2729 easier.
2730
27312012-12-14 Paulo Andrade <pcpa@gnu.org>
2732
2733 * include/lightning.h, lib/lightning.c: Add two extra wrapper
2734 functions to avoid need for excess pointer to/from word casts.
2735
2736 * check/lightning.c: Only need for pointer to/from word cast
2737 now is jit_movi, update accordingly.
2738
27392012-12-13 Paulo Andrade <pcpa@gnu.org>
2740
2741 * check/varargs.ok, check/varargs.tst: New test cases implementing
2742 simple varargs calls with a large amount of arguments to exercise
2743 excess arguments on stack.
2744
2745 * include/lightning.h: Include config.h if HAVE_CONFIG_H is
2746 defined.
2747
2748 * lib/jit_arm.c: Allocate a fpr register, not a gpr one for
2749 temporary when pushing varargs arguments in the stack.
2750
2751 * lib/jit_arm-swf.c: Correct code changing the wrong offset
2752 in jit_absr_d and jit_negr_d in software float.
2753
2754 * lib/jit_mips.c: Correct calculation of offsets of arguments
2755 on stack.
2756
2757 * lib/jit_ppc.c: Correct bogus logic for "next" offset of arguments
2758 on stack and adjust for fixed offset of stack arguments.
2759
27602012-12-12 Paulo Andrade <pcpa@gnu.org>
2761
2762 * include/lightning.h, lib/jit_arm.c, lib/jit_mips.c,
2763 lib/jit_ppc.c, lib/jit_x86.c, lib/lightning.c: Change jit_prepare
2764 to no longer receive an argument. If receiving an argument, it
2765 should be an ABI specifier, not a boolean if varargs or not,
2766 and add the new jit_ellipsis call, to specify where the
2767 ellipsis is in the C prototype of the function being called.
2768 Note that currently it is not supported to define varargs
2769 functions and it will be ignored if calling jit_ellipsis not
2770 in a prepare/finish* block, but this should be addressed.
2771
2772 * check/allocai.tst, check/alu_add.tst, check/alu_and.tst,
2773 check/alu_com.tst, check/alu_div.tst, check/alu_lsh.tst,
2774 check/alu_mul.tst, check/alu_neg.tst, check/alu_or.tst,
2775 check/alu_rem.tst, check/alu_rsh.tst, check/alu_sub.tst,
2776 check/alu_xor.tst, check/alux_add.tst, check/alux_sub.tst,
2777 check/bp.tst, check/branch.tst, check/cvt.tst, check/divi.tst,
2778 check/fib.tst, check/ldsti.tst, check/ldstr-c.tst,
2779 check/ldstr.tst, check/ldstxi-c.tst, check/ldstxi.tst,
2780 check/ldstxr-c.tst, check/ldstxr.tst, check/rpn.tst,
2781 check/lightning.c: Update for the change to jit_prepare and
2782 addition of jit_ellipsis.
2783
27842012-12-11 Paulo Andrade <pcpa@gnu.org>
2785
2786 * lib/jit_ppc-cpu.c: Make movr a function that checks arguments
2787 so that other code can safely assume it is a noop if src and dst
2788 are the same register.
2789 Implement rem{r,i}{,_u} as a div{,u}/mul/sub.
2790 Correct ANDIS, ORIS and XORIS calls to cast the argument to
2791 unsigned before the shift to avoid an assertion if the argument
2792 had the topmost bit set.
2793 Implement lshi, rshi and rshi_u as functions to test for a
2794 zero argument, that would otherwise trigger an assertion when
2795 computing the shift value.
2796 Do a simple implementation of bm{s,c}{r,i} with a temporary,
2797 "andr" of arguments and jump based on comparison with zero.
2798 Correct typo in ldxi_c.
2799
2800 * lib/jit_ppc-fpu.c: Correct wrong arguments to FDIV* and STF*.
2801
2802 * lib/jit_ppc.c: Correct wrong check for 6 instead of 8 integer
2803 arguments in registers. If calling a varargs function and
2804 passing a float or double argument, also either store the
2805 value in the stack or in integer registers, as varargs functions
2806 do not fetch it from float registers.
2807 Add "case" for new functions and incorrectly missing ones.
2808 Call libgcc's __clear_cache, that should know what to do
2809 if the hardware needs flushing cache before execution.
2810
2811 * lib/lightning.c: Do a simple/trivial logic in jit_regset_scan1,
2812 that should make it easier for the compiler to optimize it, and
2813 that also corrects the previously wrong code for big endian, and
2814 that was causing problems in ppc due to not saving all callee save
2815 registers as it was not "finding" them in the regset due to the
2816 little endian assumption bug.
2817
28182012-12-11 Paulo Andrade <pcpa@gnu.org>
2819
2820 * configure.ac: Only default to using the builtin disassembler
2821 if on GNU/Linux. This should be temporary, due to requiring
2822 /proc/self/exe.
2823 Correctly check $target_cpu for powerpc.
2824
2825 * include/lightning/jit_ppc.h: Correctly implement jit_v_num.
2826
2827 * include/lightning/jit_private.h: Declare proper prototype
2828 for jit_init_debug and jit_finish_debug.
2829
2830 * lib/jit_ppc-cpu.c: Remove code to save/restore callee save
2831 float registers, as it is not required since those float
2832 registers are not usable currently.
2833 Change prolog and epilog generation to, at least comparing
2834 code, match what gcc generates in "gcc -O0", but it is still
2835 failing in Darwin PPC, apparently due to the __clear_cache
2836 call not being enough, as frequently it will also fail to
2837 execute, and the code buffer is all zeroes.
2838
2839 * lib/lightning.c: Do not fail in jit_regset_scan1 calls due
2840 to passing 64 as argument on computers with 64 registers.
2841
28422012-12-10 Paulo Andrade <pcpa@gnu.org>
2843
2844 * lib/jit_mips-cpu.c: Correct all current test cases.
2845 Call the "xori" not the "XORI" macro for jit_xori implementation,
2846 as the XORI macro handles only 16 bit unsigned values.
2847 Call the "movr" macro, not the "movi" macro in the special
2848 case of adding or subtracting zero.
2849 Use the proper temporary register in the jit_andr implementation.
2850
28512012-12-09 Paulo Andrade <pcpa@gnu.org>
2852
2853 * check/alu.inc, check/alu_add.ok, check/alu_add.tst,
2854 check/alu_and.ok, check/alu_and.tst, check/alu_com.ok,
2855 check/alu_com.tst, check/alu_div.ok, check/alu_div.tst,
2856 check/alu_lsh.ok, check/alu_lsh.tst, check/alu_mul.ok,
2857 check/alu_mul.tst, check/alu_neg.ok, check/alu_neg.tst,
2858 check/alu_or.ok, check/alu_or.tst, check/alu_rem.ok,
2859 check/alu_rem.tst, check/alu_rsh.ok, check/alu_rsh.tst,
2860 check/alu_sub.ok, check/alu_sub.tst, check/alu_xor.ok,
2861 check/alu_xor.tst, check/alux_add.ok, check/alux_add.tst,
2862 check/alux_sub.ok, check/alux_sub.tst, check/branch.ok,
2863 check/branch.tst: New test cases for arithmetic and branch
2864 tests.
2865
2866 * check/Makefile.am: Update for new test cases.
2867
2868 * include/lightning/jit_private.h: Make the jit_reg_free_p
2869 macro shared by all backends. Previously was added for the
2870 arm backend, but is useful in the x86_64 backend when checking
2871 state of "special purpose register".
2872 Also add the new jit_class_named register class, that must be
2873 or'ed with the register value if calling jit_get_reg expecting
2874 an specific value, because the specific register value may be
2875 zero, that previously was treated as no register requested.
2876
2877 * lib/jit_arm-cpu.c: Correct argument order for T2_MVN.
2878
2879 * lib/jit_arm-swf.c: Call the proper function for double
2880 divide. The "software float" implementation just calls
2881 libgcc functions.
2882
2883 * lib/jit_arm.c: Return float/double values in the float
2884 register if using the hard float ABI.
2885
2886 * lib/jit_x86-cpu.c: Change the can_sign_extend_int_p macro
2887 to not include -0x80000000L, because there is code that
2888 "abuses" it and thinks it can negate the immediate value
2889 after calling that macro.
2890 Correct implementation of jit_subi that had a wrong code
2891 patch logic doing subtraction with reversed arguments.
2892 Correct REX prefix calculation in the jit_muli implementation.
2893 Correct logic to get/unget %*ax and %*dx registers in divremr
2894 and divremi.
2895 Correct divremi that was using the symbolic, unique %*ax
2896 value in on place (not using the _REGNO name suffix).
2897 Correct cut&paste error causing it to use "xor" instead of
2898 "or" in one code path of the jit_ori implementation.
2899 Correct several flaws when clobbering registers and/or when
2900 one of the arguments was %*cx in the rotshr wrapper function
2901 implementing most shift operations.
2902
2903 * lib/lightning.c: No longer expect that the backend be smart
2904 enough to know what to do when asking for a named register
2905 if that register is already an argument or is live. It fails
2906 if it is an argument, or if register is live, fails if cannot
2907 spill.
2908 No longer incorrectly assume that eqr_{f,d} and ltgr_{f,d} are
2909 safe to inverse value tests in jump thread optimization.
2910
29112012-12-05 Paulo Andrade <pcpa@gnu.org>
2912
2913 * check/Makefile.am, check/cvt.ok, check/cvt.tst: Add new
2914 "cvt" test case to test conversion from/to int/float types.
2915
2916 * check/lightning.c: Only define truncr_{f,d}_l in 64 bit mode.
2917
2918 * include/lightning.h: Correct typo that caused it to define
2919 jit_truncr_{f,d}_l in 32 bit mode.
2920
2921 * lib/jit_arm-cpu.c: Avoid assertion failure in the signed/unsigned
2922 extend opcodes generation as it shares an interface for 3 argument
2923 opcode generation.
2924
2925 * lib/jit_x86-cpu.c: Correct wrong argument passed to
2926 jit_unget_reg in the andi implementation and wrong byte
2927 unsigned extend code generation.
2928
2929 * lib/jit_x86-sse.c: Correct conversion from "word" to float or
2930 double as is dependent on wordsize.
2931
29322012-12-05 Paulo Andrade <pcpa@gnu.org>
2933
2934 * check/ldstr-c.ok, check/ldstr-c.tst, check/ldstxi-c.ok,
2935 check/ldstxi-c.tst, check/ldstxr-c.ok, check/ldstxr-c.tst:
2936 New test case files testing load clobbering the base and/or
2937 index register;
2938
2939 * check/ldst.inc: New file with common definition for all the
2940 ldst* test cases.
2941
2942 check/Makefile.am, check/ldsti.tst, check/ldstr.tst,
2943 check/ldstxi.tst, check/ldstxr.tst: Update for new common
2944 definitions file and new register clobber ldst tests.
2945
29462012-12-05 Paulo Andrade <pcpa@gnu.org>
2947
2948 * lib/jit_mips-fpu.c: Correct wrong register order in stxr_{f,d}
2949 in the mips backend.
2950
29512012-12-05 Paulo Andrade <pcpa@gnu.org>
2952
2953 * lib/jit_arm-vfp.c: Correct regression found in armv7l with
2954 latest test cases.
2955
29562012-12-05 Paulo Andrade <pcpa@gnu.org>
2957
2958 * check/ldstxi.tst, check/ldstxr.tst: Correct wrong argument
2959 order for 32 bit mode tests.
2960
2961 * configure.ac: Correct check for ix86 target_cpu.
2962
29632012-12-05 Paulo Andrade <pcpa@gnu.org>
2964
2965 * check/ldstr.ok, check/ldstr.tst, check/ldsti.ok,
2966 check/ldsti.tst, check/ldstxr.ok, check/ldstxr.tst,
2967 check/ldstxi.ok, check/ldstxi.tst:
2968 New test case files exercising a very large amount of
2969 register combinations to verify load/store implementation.
2970
2971 * check/Makefile.am: Update for new test cases.
2972
2973 * lib/jit_x86-cpu.c: Correct wrong argument order when
2974 computing REX prefix for {ld,st}r_T codes;
2975
29762012-12-04 Paulo Andrade <pcpa@gnu.org>
2977
2978 * lib/jit_mips-fpu.c, lib/jit_mips.c: Implement missing mips
2979 jit_sqrtr_{f,d} codes.
2980
2981 * check/all.tst, include/lightning.h, lib/jit_print.c: Change
2982 declaration order and call order in all.tst of {add,sub}c and
2983 {add,sub}x. *c must be called before to set the carry and *x
2984 second to use the carry and keep it set. The wrong call order
2985 was causing all.tst to fail in mips, where a register is
2986 allocated to keep a global carry state.
2987
29882012-12-04 Paulo Andrade <pcpa@gnu.org>
2989
2990 * include/lightning/jit_mips.h, lib/jit_mips-cpu.c,
2991 lib/jit_mips-fpu.c, lib/jit_mips.c: Correct float/double
2992 argument handling and make the mips backend pass the initial
2993 test cases.
2994
2995 * include/lightning.h, ib/jit_print.c, lib/lightning.c:
2996 Add extra enum values for argument handling functions that
2997 could not be abstracted to the current codes, that is, when
2998 float values need to move from/to gpr from/to fpr. It would
2999 be more tempting to add such primitives, but they would have
3000 wordsize limitations, and it is not expected to add codes
3001 with one gpr argument for 64 bit and two for 32 bit.
3002
3003 * lib/jit_ppc.c: Check _jit->function before calling jit_epilog()
3004 to avoid a runtime exception.
3005
30062012-12-04 Paulo Andrade <pcpa@gnu.org>
3007
3008 * include/lightning/jit_mips.h, lib/jit_mips.c: Update to
3009 make the mips backend compile in a qemu image.
3010
3011 * lib/jit_ppc.c: Minor adaptations to help in having the
3012 ppc backend compilable.
3013
30142012-12-03 Paulo Andrade <pcpa@gnu.org>
3015
3016 * configure.ac, include/lightning/jit_private.h, lib/jit_arm-cpu.c,
3017 lib/jit_arm-swf.c, lib/jit_arm.c, check/Makefile.am: Correct
3018 implementation of the arm backend port to build and pass the
3019 current test cases. Tested on armv7 with softfp abi.
3020
3021 * lib/jit_disasm.c: Rename and change prototype of static
3022 disassemble function as in the arm backend it is required
3023 to access state information stored in the jit_state_t object.
3024
3025 * check/3to2.tst, check/add.tst: Correct test case code assuming
3026 JIT_RO and JIT_RET are the same, and even if they are the same,
3027 the logic was incorrect because it must always call jit_retval*
3028 to fetch a function call return before any other instruction.
3029 The arm backend hash a special condition if jit_retval is not
3030 called, because "r0" is not JIT_R0, but is JIT_RET and *also*
3031 the first argument for a called function, so JIT_RET must be
3032 only used as an argument to jit_retval.
3033
30342012-12-03 Paulo Andrade <pcpa@gnu.org>
3035
3036 * check/all.tst, check/lightning.c: Only declare or use 64 bit
3037 interfaces on 64 bit builds.
3038
3039 * check/fib.tst: Use simpler logic to not need preprocessor
3040 conditionals for 32 or 64 bit.
3041
3042 * include/lightning.h: Only declare 64 bit macros on a 64 bit
3043 build. Code using lightning must know about wordsize and the
3044 jit generation limitations, also, this way it generates a
3045 compile time failure, not a runtime assertion.
3046
3047 * include/lightning/jit_x86.h: Correct typo in macro name.
3048
3049 * lib/jit_arm.c, lib/jit_arm-cpu.c, lib/jit_mips.c,
519a9ea1 3050 lib/jit_mips-cpu.c, lib/jit_ppc.c, lib/jit_ppc-cpu.c,
4a71579b
PC
3051 lib/jit_x86.c, lib/jit_x86-cpu.c: Correct wrong code to get
3052 current jit function pointer.
3053
3054 * lib/lightning.c: Move call to the simplify() optimization
3055 to after register liveness is known. Previous code did work
3056 by accident but now with proper test cases the problem was
3057 noticed.
3058
3059 * lib/jit_disasm.c: Always cast bfd_vma to long long when
3060 passing it as printf argument.
3061
30622012-12-03 Paulo Andrade <pcpa@gnu.org>
3063
3064 * configure.ac, check/Makefile.am, check/check.sh,
3065 doc/Makefile.am, include/lightning/Makefile.am,
3066 lib/Makefile.am: Correct make distcheck.
3067
30682012-12-02 Paulo Andrade <pcpa@gnu.org>
3069
3070 * lib/jit_ppc.c: Assign copyright ownership to FSF.
3071
3072 * lib/jit_x86-cpu.c: Correct integer multiplication that was
3073 generating code with reversed register arguments.
3074
3075 * check/rpn.ok, check/rpn.tst: New test case file.
3076
30772012-12-02 Paulo Andrade <pcpa@gnu.org>
3078
3079 * lib/jit_x86-cpu.c, lib/jit_x86-sse.c, lib/jit_x86-x87.c:
3080 Actually change copyright owner to FSF as avertised.
3081
3082 * lib/jit_arm-cpu.c, lib/jit_arm-swf.c,
3083 lib/jit_arm-vfp.c, lib/jit_arm.c,

3085 lib/jit_ppc-cpu.c, lib/jit_ppc-fpu.c, lib/jit_ppc.c: New
3086 files implementing initial code different jit backends.
3087
3088 * include/lightning/jit_private.h: Add extra field to the
3089 private jit_patch_t type, required by the arm port.
3090
3091 * lib/Makefile.am: Update for the new backend implementation
3092 files.
3093
30942012-12-02 Paulo Andrade <pcpa@gnu.org>
3095
3096 * check/Makefile.am: Add proper "make clean" rule and missing
3097 check.sh to EXTRA_DIST.
3098
30992012-12-02 Paulo Andrade <pcpa@gnu.org>
3100
3101 * .gitignore: Update pattern of ignored files.
3102
3103 * check/Makefile.am: Add rule to build liblightning.la dependency
3104 in case of running "make check" before building the library.
3105

3118 lightning/sparc/asm.h, lightning/sparc/core.h,
3119 lightning/sparc/fp.h, lightning/sparc/funcs.h:
3120 Removed. The core logic is used in the new code, and new mips
3121 and arm ports will be added. At first, sparc will not be
3122 supported as it has not yet been ported to the new engine.

3126 * tests/Makefile.am, tests/3to2.c, tests/3to2.ok, tests/add.c,

3135 tests/rpnfp.ok, tests/sete.c, tests/sete.ok, tests/testfp.c,
3136 tests/testfp.ok, tests-run-test: Removed previous test suite, in
3137 favor of a newer one in the check subdirectory.
3138
3139 * check/3to2.ok, check/3to2.tst, check/add.ok, check/add.tst,
3140 check/allocai.ok, check/allocai.tst, check/bp.ok, check/bp.tst,
3141 check/divi.ok, check/divi.tst, check/fib.ok, check/fib.tst:
3142 New sample input for the new test program, loosely matching
3143 several of the previous test cases.
3144
3145 * check/Makefile.am: New test suite makefile.
3146
3147 * check/check.sh, check/run-test: New wrapper files for the
3148 new test suite.
3149
3150 * check/lightning.c: New file. The main driver of the new test
3151 suite, that compiles to a parser of a very simple assembly like
3152 language, generates jit and executes it.
3153
3154 * check/all.tst: New file. A generic debug and sample test file
3155 with a directive to prevent it from being executed, and useful to
3156 read disassembly of all possible instructions, using a fixed set
3157 of registers.
3158
3159 * include/Makefile.am, include/lightning.h,
3160 include/lightning/Makefile.am, include/lightning/jit_arm.h,
3161 include/lightning/jit_mips.h, include/lightning/jit_ppc.h,

3165 lib/jit_x86.c, lib/lightning.c: New files. These files are
3166 written from scratch, only by <pcpa@gnu.org>, and have now
3167 copyright assignment to the FSF. This is the core of the new
3168 lightning rework. Previously it was integrated in code with
3169 a garbage collector and several custom types like vectors and
3170 hash tables, so this first code merge with lightning converts
3171 that code into a library extracting only the jit bits, and at
3172 first only for x86_64 GNU/Linux.
3173
3174 * lightning.h, m4/lightning.m4: Removed. These are no longer
3175 required in the new lightning code.
3176
3177 .gitignore, Makefile.am, configure.ac: Update for the new
3178 lightning code.
3179
31802012-12-02 Paulo Andrade <pcpa@gnu.org>
3181 * .cvsignore: Removed for extra cleanup.
3182
3183 * build-aux: Rename directory to m4.
3184
3185 * m4: Renamed to "default" name and for consistency with merge
3186 with code rework to be imported in lightning.
3187
3188 * .gitignore, configure.ac, Makefile.am, doc/Makefile.am:
3189 Update for build-aux to m4 rename.
3190

3196 opcode/ppc.h, opcode/sparc-dis.c, opcode/sparc-opc.c, opcode/sparc.h,
3197 opcode/sysdep.h: Removed. Do not bundle GNU binutils files.
3198
3199 * aclocal.m4, configure, Makefile.in, config.h.in, doc/Makefile.in,
3200 lightning/Makefile.in, tests/Makefile.in: Removed. Do not maintain
3201 autogenerated files that also generate too much diff noise when
3202 regenerated in git.
3203
3204 * build-aux/help2man, build-aux/texinfo.tex, build-aux/texi2dvi:
3205 Removed. Buildenvironment must have an up to date version from
3206 upstream installed.
3207
3208 * build-aux/config.guess, build-aux/config.sub, build-aux/depcomp,
3209 build-aux/install-sh build-aux/mdate-sh build-aux/missing: Removed.
3210 Do not maintain a copy of automake files in git. Release tarballs
3211 must use an up to date version.
3212
3213 * lightningize.in, doc/lightningize.1: Removed. Do not encourage
3214 bundling lightning in other packages. It should use a system package
3215 or a proper thirdy part subdirectory.
3216
3217 * INSTALL: Removed. Autoreconf removes it and creates a symlink
3218 when regenerating files, so, avoid conflicts in git and let
3219 automake create the symlink.
3220
3221 * .gitignore: Add INSTALL and autogenerated files.
3222
3223 * configure.ac, Makefile.am: Update for removal of opcode subdir,
3224 auto generated files and lightningize.
3225
3226 * tests/Makefile.am, tests/3to2.c, tests/add.c, tests/bp.c,

3236 tests/fibit.c, tests/funcfp.c, tests/incr.c, tests/printf.c,
3237 tests/rpn.c, tests/rpnfp.c, tests/sete.c, tests/testfp.c:
3238 Remove LIGHTNING_CROSS, it is half supported and incomplete.
3239
3240 * tests/3to2.c, tests/funcfp.c, tests/rpnfp.c: Remove preprocessor
3241 check on JIT_FPR. If no hardware registers are available, the backend
3242 must provide an alternative for software float.
3243
3244 * lightning/ppc/core.h, lightning/sparc/core.h, tests/Makefile.am:
3245 Remove JIT_NEED_PUSH_POP. It is absolutely not trivial to implement
3246 properly on some backends due to stack alignment constraints, and
3247 whenever it is required, using jit_allocai and using a properly
3248 aligned stack vector, or a heap buffer, is better.
3249
3250 * tests/push-pop.c, tests/push-pop.ok: Removed due to
3251 JIT_NEED_PUSH_POP no longer available.
3252
32532011-02-28 Paolo Bonzini <bonzini@gnu.org>

3362
3363 * lightning/ppc/funcs.h (jit_flush_code): modified the computation
3364 of start/end. The pointer arithmetic was done without casting. It
519a9ea1 3365 prevented compilation with recent gcc versions.
4a71579b
PC

3367 incorrect. Should have been 4 bytes below SP (not above).
519a9ea1
PC
3368 * lightning/ppc/core.h (jit_popr_i): The offset for the load was
3369 incorrect. Should have been 0 (not +8).

3385 the core.h has no effect on the 32-bit backend.
3386 * lightning/i386/core-64.h: Place JIT_R1/JIT_R2 in R10/R11,
3387 place outgoing arguments in the right spot from the beginning,
3388 define jit_save, fix jit_reg8/jit_reg16.
3389
33902008-06-15 Paolo Bonzini <bonzini@gnu.org>
3391
3392 * lightning/i386/core-64.h: Rewrite argument passing to
3393 support up to 6 arguments and generate less code.
