14 2022-10-05 Paulo Andrade <pcpa@gnu.org>
16 * check/lightning.c: Remove -Dmacro=value from usage and attempt
17 to parse it. It was buggy and not properly implemented. Now
18 it pass any extra options to the generated jit. To pass any
19 option starting with '-' need to also use '--'.
20 * check/collatz.e: New sample file showing an example of jit
23 2022-10-04 Paulo Andrade <pcpa@gnu.org>
25 * include/lightning/jit_private.h: Add new flag to jit_block_t.
26 * lib/lightning.c: Rewrite register liveness and state at block
27 entry code to avoid a very expensive and non scaling code path.
28 Now it attempts to do as few as possible recomputations when
29 merging state of adjacent blocks, still doing one extra nop pass
30 (in the sense that it will not find any changes) to make sure the
33 2022-09-30 Paulo Andrade <pcpa@gnu.org>
35 * include/lightning/jit_private.h: Implement new data structures
37 * lib/jit_disasm.c: Extra disassemble code for riscv constant pool.
38 * lib/jit_riscv-cpu.c: Modify movi to use constant pool if 3 or
39 more instructions are required to construct constant and modify
40 movi_p to use a pc relative load from a constant pool.
41 lib/jit_riscv-sz.c: Update for new constant pool code. Most
42 instructions that need 64 bit constants are significantly reduced.
43 * lib/jit_riscv.c: Implement most of the constant pool code.
44 * lib/jit_size.c: Update for estimate of code generation size.
45 * lib/lightning.c: Update for riscv specific code, and also make
46 sure to mprotect the constant pool as executable.
48 2022-09-08 Paulo Andrade <pcpa@gnu.org>
50 * lib/jit_fallback.c: Implement fallback compare and swap with
52 * check/Makefile.am: Update for new cas{r,i} simple test.
53 * check/catomic.c, check/catomic.ok: New test case for
54 simple compare and swap atomic operation.
55 * check/lightning.c: Add entries to be able to use
56 the new compare and swap atomic operation. Still missing
57 a general test, only the basic C version.
58 * include/lightning.h.in: Include pthread.h, even if not
59 needing a fallback compare and swap.
60 * include/lightning/jit_private.h: Add support for a register pair
61 in second argument. Required by the new casr and casi operations.

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

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

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

112 * check/live.ok: New file.
113 * check/live.tst: New file.
114 * doc/body.texi: Add documentation for the live instruction and
115 for jit_get_reg/jit_get_unreg. Fix menu entries.
116 * include/lightning.h.in (jit_get_reg, jit_unget_reg): Expose the
117 macros in the public header file.
118 * include/lightning/jit_private.h (jit_get_reg, jit_unget_reg):
119 Remove the macros from the private header file.
121 2021-04-03 Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de>
123 * Makefile.am, check/Makefile.am, doc/Makefile.am,
124 lib/Makefile.am: Include $(top_builddir)/include in include paths
125 for the autoconf-generated header file lightning.h.
127 2021-04-03 Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de>
129 * doc/.gitignore: Add version.texi to list of ignored files.
130 * doc/version.texi: Remove file from version control.
132 2020-18-04 Paulo Andrade <pcpa@gnu.org>
134 * lib/jit_x86-cpu.c, lib/jit_x86.c: Implement %rip relative
135 calls and jumps on x86_64. Currently very conservative, assuming
136 a jit block can be larger than 2G, so, if a jump or call is in
137 the same jit generation, but target is unknown, use an indirect
138 branch (could have an option to assume a jit code block is
139 never larger than 2G). Also a deoptimization is that now does
140 not always generate ip relative jmpi; previously implicitly
141 assumed jmpi would never be larger than 2G. Overall still an
144 2020-23-01 Paulo Andrade <pcpa@gnu.org>
146 * lib/lightning.c: Add a proper fix to the condition of considering
147 a register dead at entry of a block when it modifies the register
148 !after! a branch to a target where it is live.
149 The correction is just to split blocks on branches. It uses an
150 extra label per branch, but makes following the code simpler and
151 avoid costly searches.
153 2020-22-01 Paulo Andrade <pcpa@gnu.org>
155 * lib/lightning.c: Correct a special condition of a register
156 only assigned in a block, and incorrectly marked as dead before
157 a jump where the register is live.
159 2019-10-04 Paulo Andrade <pcpa@gnu.org>
161 * check/lightning.c, include/lightning/jit_private.h,
162 include/lightning/jit_x86.h, lib/jit_x86-cpu.c, lib/jit_x86-sz.c,
163 lib/jit_x86.c: Correct issues with MinGW64 that defines _WIN32
164 and needs long long for jit_word_t.
166 2019-09-16 Paulo Andrade <pcpa@gnu.org>
168 * lib/lightning.c: Do not add registers that are never modified
169 to the set of registers to scan for live range, what might
170 consume a lot of cpu time, doing nothing.
172 2019-09-16 Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de>
174 * include/lightning/jit_x86.h, lib/jit_x86.c: Correct x86_64
175 backend, made %r12 a callee-save register as dictated by the
178 2019-09-16 Paulo Andrade <pcpa@gnu.org>
180 * Makefile.am: Do not force CFLAGS for the get_jit_size target.
181 * check/lightning.c: Drop __ppc__ check.
182 * include/lightning.h.in: Drop __ppc__ check. Add new
183 jit_flag_vararg flag, for special case in powerpc 32 bit using
184 the SYSV abi, and need to pass an extra argument during code
186 * include/lightning/jit_ppc.c: Drop __ppc_ check. Remove the
187 ABI_ELFv2 macro, as it now directly checks for the _CALL_ELF
188 value when/if appropriate.
189 * include/lightning/jit_private.h: Drop __ppc_ check. Check for
190 _CALL_AIXDESC to define extra data to handle function
192 * lib/jit_ppc-cpu.c: Update to check for _CALL_SYSV; assume
193 !_CALL_SYSV == (_CALL_AIX || _CALL_LINUX). Significant code
194 rework for the SYSV abi.
195 * lib/jit_ppc-sz.c: Update for the SYSV abi.
196 * lib/jit_ppc.c: Update for the SYSV abi. Add matching va_list
197 type. Drop __ppc__ check.
198 * lib/jit_size.c: Drop __ppc_ check.
199 * lib/lightning.c: Drop __ppc__ check. Add proper check for
200 __powerpc__ and _CALL_AIXDESC to manage function descriptors.
201 * lib/size.c: Update to drop __pppc_ check and SYSV abi.
203 2019-08-30 Paulo Andrade <pcpa@gnu.org>
205 * lib/jit_mips-cpu.c: Use JALR to get the same effect as JR, as
206 in mips32r6 JR generates an illegal instruction. Thanks to
207 Bruno Haible for providing a patch and the information, reported at
208 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=925129
211 2019-08-29 Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de>
213 * include/lightning/jit_private.h: Move definition of offsetof
214 from the public header file here.
216 * configure.ac, include/Makefile.am, include/lightning.h,
217 include/lightning.h.in: Generate lightning.h from lightning.in.h
218 and remove the dependence on config.h from the public header file.
220 2019-06-04 Paulo Andrade <pcpa@gnu.org>
222 * include/lightning/jit_riscv.h, lib/jit_riscv-cpu.c,
223 lib/jit_riscv-fpu.c, lib/jit_riscv-sz.c, lib/jit_riscv.c:
224 Implement riscv port. Only 64 bit Linux supported. Built on
227 * check/all.tst, check/float.tst, configure.ac, include/lightning.h,
228 include/lightning/Makefile.am, include/lightning/jit_private.h,
229 lib/Makefile.am, lib/jit_disasm.c, lib/jit_size.c, lib/lightning.c:
230 Minor updates for the new riscv port.
232 2019-06-04 Paulo Andrade <pcpa@gnu.org>
234 * lib/jit_alpha.c lib/jit_ia64.c lib/jit_mips.c lib/jit_sparc.c:
235 Correct assertion of _jitc->regarg after emiting an instruction.
236 jit_carry may be set, but not an argument to the current instruction.
238 2019-06-01 Paulo Andrade <pcpa@gnu.org>
240 * lib/lightning.c: Correct assertion on jit_unget_reg when the
241 argument is jit_carry, and jit_carry was not used in the
244 2019-06-01 Paulo Andrade <pcpa@gnu.org>
246 * include/lightning/jit_private.h: Remove no longer need
247 setmask field of jit_block_t and blockmask from jit_compiler_t.
249 * lib/lightning.c: Rework of register live and unknown state
250 information during jit generation. It no longer recurses nor
251 do dangerous bit unset of registers in unknown state. The
252 only pitfall known, that must be taken care now is that jmpr
253 (or jmpi to not a jit node) is treated as a function call, as
254 otherwise it would need to consider all registers live, and
255 spill/reload during all jit generation.
257 2018-12-28 Paulo Andrade <pcpa@gnu.org>
259 * lib/jit_disasm.c: Release bfd handle. Thanks for patch to
260 Marc Nieper-Wißkirchen.
262 2018-08-30 Paulo Andrade <pcpa@gnu.org>
264 * lib/jit_disasm.c: Add hints to select hppa disassembler.
266 * lib/jit_hppa-cpu.c: Correct address of vastart when all
267 argument registers were used as non vararg arguments.
269 * lib/jit_hppa-fpu.c: Disable load/store of rv,ix,rb where
270 rv is the value, ix is an register or integer offset and rb
271 is a base register. These should be better tested, as they do
272 not work on all environments (fail on qemu-hppa).
274 2018-04-20 Paulo Andrade <pcpa@gnu.org>
276 * include/lightning/jit_private.h: Add new register classes to
277 flag float registers and double only registers, required for sparc64
278 where only low 32 bit fpr registers can be used for single precision
280 Add new 128 bit jit_regset_t type for sparc64 register set.
282 * include/lightning/jit_sparc.h, lib/jit_sparc-cpu.c, lib/jit_sparc-fpu.c,
283 lib/jit_sparc-sz.c, lib/jit_sparc.c: Update for 64 bits sparc.
285 * lib/lightning.c: Update for new jit_regset_t required for sparc64.
287 2018-02-26 Paulo Andrade <pcpa@gnu.org>
289 * check/lightning.c, include/lightning.h: Add the new jit_va_push
290 interface. That should be called when passing a va_list to a C
291 function. This is required because on Alpha a va_list is passed
292 by value, and lightning does not know about data types, so, cannot
293 understand it is pushing a va_list as argument.
295 * lib/jit_names.c, lib/lightning.c: Minor changes for the new
298 * check/cva_list.c: Update only test case using jit_va_push, to
299 pass a va_list to a C function.
301 doc/body.texi: Better documentation of the varargs interface.
303 * jit_alpha.c, jit_alpha-cpu.c: Update to properly push a
304 C va_list and correctly calculate varargs offset.
306 * lib/jit_aarch64-sz.c, lib/jit_aarch64.c, lib/jit_alpha-sz.c,

310 lib/jit_sparc-sz.c, lib/jit_sparc.c, lib/jit_x86-sz.c, lib/jit_x86.c:
311 Update for the new jit_va_push interface.
313 2018-02-22 Paulo Andrade <pcpa@gnu.org>
315 * lib/jit_alpha-cpu.c: Always set t12 to the address of the
316 current function, to properly work on all systems. Previously
317 the shortcut did only work on Tru64. For Linux and glibc the
320 2018-02-22 Paulo Andrade <pcpa@gnu.org>
322 * lib/jit_aarch64.c, lib/jit_alpha.c, lib/jit_arm.c,
323 lib/jit_mips.c, lib/jit_ppc.c, lib/jit_sparc.c, lib/jit_x86.c:
324 Correct wrong logic in usage of jit_live in jit_retr. The
325 problem is that if a temporary is required during epilog,
326 the return register might be allocated, so, jit_live must always
329 2018-01-31 Paulo Andrade <pcpa@gnu.org>
331 * lib/lightning.c: Avoid deep recursions when computing live
334 2018-01-31 Paulo Andrade <pcpa@gnu.org>
336 * lib/jit_mips-cpu.c: Correct frame size and varargs
337 initialization for the n32 abi.
338 * lib/jit_mips.c, lib/jit_mips-fpu.c: Correct 32 bit abis
341 2017-09-13 Paulo Andrade <pcpa@gnu.org>
343 * configure.ac: Add check for binutils 2.29 prototype to the
344 disassembler function.
345 * lib/jit_disasm.c: Adapt for binutils 2.29 change.
347 2017-06-09 Paulo Andrade <pcpa@gnu.org>
349 * include/lightning/jit_private.h, lib/lightning.c: Add a
350 second pass from start when computing register live ranges.
351 This should be used temporarily, and is required for certain
352 loop constructs, with several consecutive blocks not referencing
355 2016-05-05 Paulo Andrade <pcpa@gnu.org>
357 * lib/lightning.c: Correct wrong movr simplification,
358 remove no longer needed code to set return registers live
359 and update live register set when reaching a label boundary,
360 but do not descend if the block has been already visited.
361 The later need some tuning for complex code generation, where
362 it will still have issues.
364 2015-11-30 Paulo Andrade <pcpa@gnu.org>
366 * doc/body.texi: Change documentation to no longer say
367 it is a variant of the Fibonacci sequence, and document
368 a proper implementation.
369 Thanks to Jon Arintok for pointing out that the Fibonacci
370 sequence generation was incorrect. It was documented, but
373 * check/fib.tst, check/fib.ok, check/bp.tst, check/bp.ok,
374 doc/ifib.c, doc/rbif.c: Implement a proper Fibonacci
375 sequence implementation.
377 2015-07-03 Paulo Andrade <pcpa@gnu.org>
379 * lib/jit_mips-cpu.c: Correct definition of htonr_ul.
380 Correct prolog/epilog/va* routines to work on o64 abi.
382 * lib/jit_mips-fpu.c: Correct load of double literal
383 argument when not using a data buffer.
384 Remove alignment correction in vaarg_d if using the
387 * lib/jit_mips.c: Correct code to allow creating variadic
388 jit functions when using the new mips abi.
390 * lib/jit_rewind.c: Minor adjust for rewind when using
391 the new mips abi, if there are varargs arguments in
394 2015-06-06 Paulo Andrade <pcpa@gnu.org>
396 * lib/jit_ia64-cpu.c: Search backward for the last output
397 register used, otherwise would stop too early if a float
398 argument used the slot.
399 Correct offset of first va_list argument, and use proper
402 * lib/jit_ia64-fpu.c: Add new functions to move a gpr
403 to a fpr register, to counterpart the ones that move a
404 fpr to a gpr. These are required to properly implement
405 jit_getarg*_{f,d} on complex prototypes, or variadic
408 * lib/jit_ia64-sz.c: Update for support to jit variadic
411 * lib/jit_ia64.c: Implement proper abi for variadic
414 2015-06-04 Paulo Andrade <pcpa@gnu.org>
416 * lib/jit_rewind.c: New file implementing generic functions
417 to "rewind", or rewrite IR code sequences.
419 * include/lightning.h: Add several new codes, that previously
420 were a function call, that would synthesize the operation.
421 Now, there is a code for the operation, and a new flag to
422 know an operation is synthesized.
424 * include/lightning/jit_private.h: Add several new macros to
425 help construct synthesized IR code sequences.
427 * lib/Makefile.am: Update for lib/jit_rewind.c.
429 * lib/jit_disasm.c: Update for a small rework on jit_node_t,
430 so that --enable-devel-disassembler does not need a change
431 in the layout of jit_node_t.
433 * lib/jit_names.c: Update for the new codes.
435 * lib/jit_print.c: Update to print more readable output, and
436 flag synthesized IR code sequences.
438 * lib/jit_aarch64-sz.c, lib/jit_aarch64.c,
439 lib/jit_arm-sz.c, lib/jit_arm.c, lib/jit_x86-sz.c,
440 lib/jit_x86.c: Update for new synthesized IR code sequences.
442 * lib/jit_ppc-cpu.c, lib/jit_ppc-fpu., lib/jit_ppc-sz.c,
443 lib/jit_ppc.c, lib/jit_mips-cpu.c, lib/jit_mips-fpu.c,

445 lib/jit_s390-sz.c, lib/jit_s390.c: Update for new synthesized
446 IR code sequences and correct bugs in the initial varargs
447 implementation support.
449 * lib/jit_alpha-sz.c, lib/jit_alpha.c, lib/jit_hppa-sz.c,
450 lib/jit_hppa.c, lib/jit_ia64-sz.c, lib/jit_ia64.c,
451 lib/jit_sparc-sz.c, lib/jit_sparc.c: Add generic, untested
452 support for the new synthesized IR code sequences. Known
453 most likely broken right now, and should be corrected once
454 access to these hosts is available.
456 * lib/lightning.c: Update for new IR codes, and add support
457 for not yet existing instructions that change third argument.
459 * size.c: Change to use different tables for LE and BE PowerPC.
460 Correct a wrong endif for x32.
462 2015-05-25 Paulo Andrade <pcpa@gnu.org>
464 * check/cva_list.c: New file implementing a test to ensure
465 the value returned by jit_va_start is a valid C va_list.
467 * check/va_list.ok: New simple helper file, as now the
468 va_list.tst test is enabled.
470 * check/va_list.tst: Rewritten for an extensive variadic
473 * check/Makefile.am: Update for the new tests.
475 * lib/jit_arm-cpu.c, lib/jit_arm-swf.c, lib/jit_arm-vfp.c,
476 lib/jit_arm.c: Correct broken software float in a previous
477 commit. Note that the hard float abi implementation is known
478 broken at this time, for special cases involving variadic
479 functions, and should be corrected next.
481 lib/jit_x86-cpu.c, lib/jit_x86-sz.c, lib/jit_x86.c: Correct
482 the jit_va_list_t semantics to match C va_list.
484 2015-05-24 Paulo Andrade <pcpa@gnu.org>
486 * lib/Makefile.am: Bump library major. This is a preparation
487 for a rework that was due for quite some time, but that is
488 now required to properly implement variadic jit functions.
489 The rework is mainly required to know at prolog parsing, if
490 a function is variadic or not. This will benefit a few
491 backends, and is mandatory for the hard float arm abi.
492 The rework was already planned for quite some time, to
493 be able to use a variable stack framesize, and for leaf
494 functions optimization where applicable.
495 The change will be source compatible, but will change
496 some internals, and jit_code_t values, as some new will
498 The only behavior change is that, jit_arg_register_p may
499 change return value on hard float arm abi, if called before
500 or after jit_ellipsis. Common sense anyway, would say to
501 make that call after jit_ellipsis, but documentation
502 should be updated for it.
504 2015-05-24 Paulo Andrade <pcpa@gnu.org>
506 * lib/jit_aarch64-fpu.c, lib/jit_aarch64.c: Correct base
507 aarch64 varargs code.
509 2015-05-24 Paulo Andrade <pcpa@gnu.org>
511 * check/lightning.c: Clearly run check if clang is the system
514 2015-05-20 Paulo Andrade <pcpa@gnu.org>
516 * lib/jit_sparc-cpu.c, lib/jit_sparc-fpu.c, lib/jit_sparc.c:
517 Add base support to jit vararg functions to the sparc backend.
519 2015-05-20 Paulo Andrade <pcpa@gnu.org>
521 * lib/jit_alpha-cpu.c, lib/jit_alpha-fpu.c, lib/jit_alpha.c:
522 Add base support to jit vararg functions to the alpha backend.
524 2015-05-19 Paulo Andrade <pcpa@gnu.org>
526 * lib/jit_hppa-cpu.c, lib/jit_hppa-fpu.c, lib/jit_hppa.c:
527 Add base support to jit vararg functions to the hppa backend.
529 2015-05-10 Paulo Andrade <pcpa@gnu.org>
531 * lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c, lib/jit_ia64.c:
532 Add base support to jit vararg functions to the ia64 backend.
534 2015-05-10 Paulo Andrade <pcpa@gnu.org>
536 * lib/jit_ia64-fpu.c, lib/jit_ia64.c: Correct movi_d_w
537 and movi_f_w implementation to work when not using a
538 data buffer. This causes the check varargs.tst to
539 work when passing "-d" to the lightning test tool.
541 2015-05-10 Paulo Andrade <pcpa@gnu.org>
543 * lib/jit_ia64.c: Implement inline assembly cache flush,
544 required on multiprocessor systems.
546 2015-05-06 Paulo Andrade <pcpa@gnu.org>
548 * lib/jit_mips-cpu.c, lib/jit_mips-fpu.c, lib/jit_mips.c:
549 Add base support to jit vararg functions to the mips backend.
550 Currently only supported on the o32 abi, until access to a
551 n32 system is arranged.
553 2015-05-05 Paulo Andrade <pcpa@gnu.org>
555 * lib/jit_ppc-cpu.c, lib/jit_ppc-fpu.c, lib/jit_ppc.c:
556 Add base support to jit vararg functions to the PowerPC backend.
558 2015-05-02 Paulo Andrade <pcpa@gnu.org>
560 * lib/jit_s390-cpu.c, lib/jit_s390-fpu.c, lib/jit_s390.c:
561 Add base support to jit vararg functions to the s390 backend.
563 2015-05-01 Paulo Andrade <pcpa@gnu.org>
565 * lib/jit_arm-cpu.c, lib/jit_arm-swf.c, lib/jit_arm-vfp.c,
566 lib/jit_arm.c: Add base support to jit vararg
567 functions to the arm backend.
569 2015-04-30 Paulo Andrade <pcpa@gnu.org>
571 * lib/jit_aarch64-cpu.c, lib/jit_aarch64-fpu.c,
572 lib/jit_aarch64.c: Add base support to jit vararg
573 functions to the aarch64 backend.
575 2015-04-27 Paulo Andrade <pcpa@gnu.org>
577 * include/lightning.h, include/lightning/jit_private.h,
578 lib/jit_names.c, lib/lightning.c: Add initial support
579 for the new jit_va_start, jit_va_arg, jit_va_arg_d, and
580 jit_va_end interfaces. The jit_va_start call is supposed
581 to return a va_list compatible pointer, but not yet
582 decided if it will be "declared" stdarg compatible,
583 as for now only x86 support has been added (and should
584 be compatible), but issues may arise on other backends.
586 * check/lightning.c: Add wrappers to call the new jit_va_*
589 * lib/jit_x86-cpu.c, lib/jit_x86.c: Implement the new
592 * lib/jit_x86-sz.c: Add fields, but not yet fully updated,
593 as this is an intermediate commit.
595 * lib/jit_aarch64-sz.c, lib/jit_aarch64.c,
596 lib/jit_alpha-sz.c, lib/jit_alpha.c,
597 lib/jit_arm-sz.c, lib/jit_arm.c,

602 lib/jit_s390-sz.c, lib/jit_s390.c,
603 lib/jit_sparc-sz.c, lib/jit_sparc.c: Prepare for the
604 new jit_va_* interfaces. Not yet implemented, and will
605 cause an assertion if used.
607 * check/va_list.tst: Simple early test case, that works
608 on x86_64, x32, ix86, cygwin, and cygwin64.
610 2015-02-17 Paulo Andrade <pcpa@gnu.org>
612 * include/lightning.h, include/lightning/jit_private.h,
613 lib/jit_aarch64-cpu.c, lib/jit_aarch64.c,
614 lib/jit_alpha-cpu.c, lib/jit_alpha.c,

621 lib/jit_sparc-cpu.c, lib/jit_sparc.c,
622 lib/jit_x86-cpu.c, lib/jit_x86.c: Implement the new
623 jit_allocar(offs, size) interface, that receives
624 two integer registers arguments, allocates space
625 dynamically in the stack, returns the offset in
626 the first argument, and uses the second argument
627 for the size in bytes of the memory to be allocated.
629 * check/allocar.ok, check/allocar.tst: New files
630 implementing test cases for the new jit_allocar
633 * check/Makefile.am, check/lightning.c: Update for
634 the new test case and interface.
636 * doc/body.texi: Add documentation of the new
639 2015-02-17 Paulo Andrade <pcpa@gnu.org>
641 * include/lightning/jit_x86.h, lib/jit_x86-cpu.c,
642 lib/jit_x86-x87.c: No longer make st(7) available.
643 Need to keep one x87 slots empty to avoid exceptions.
644 This has the side effect of no longer needing the
645 hackish emms instruction before a function call.
647 2015-02-16 Paulo Andrade <pcpa@gnu.org>
649 * lib/lightning.c: Remove the jit_regno_patch bitfield
650 register fields before actual emit, as it is only really
651 used before emit, otherwise, on special conditions it
652 may consider live registers as dead during code emit.
654 2015-02-15 Paulo Andrade <pcpa@gnu.org>
656 * lib/jit_x86-cpu.c, lib/jit_x86-sse.c, lib/jit_x86-x87.c:
657 Correct encoding of ldxr* stxr* in the x32 abi. If the
658 displacement register is negative, it would generate
659 a 64 bit instruction with a 32 bit unsigned displacement.
661 * check/ranger.tst, check/ranger.ok: New files, implementing
662 a test case for negative loads and stores. This is range.tst
663 converted to use registers instead of immediate offsets.
665 check/Makefile.am: Update for the new test case.
667 2015-02-07 Paulo Andrade <pcpa@gnu.org>
669 * lib/jit_size.c: Preventively use at least 144 bytes
670 if JIT_INSTR_MAX is less than it. The logic is not
671 guaranteed to be 100% precise, it is mostly heuristics
672 to allocate a buffer with as close as possible size,
673 but a wrong value may cause code generation to write
674 past the end of the buffer.
676 2015-02-03 Paulo Andrade <pcpa@gnu.org>
678 * lib/lightning.c: Correct the reason the bug in
679 simplify_stxi was not triggered before, it was due to
680 incorrectly resetting the value->code field, what was
681 causing it to never properly optimize:
684 when Rb0 == Rb1, Rt0 == Rt1 and Im0 == Im1
685 There was another possible issue, that has been also
686 addressed in this commit, that would be the case of
687 Rbn == Rtn, where no redundancy removal is possible.
689 2015-02-03 Paulo Andrade <pcpa@gnu.org>
691 * lib/lightning.c: Correct wrong check in simplify_stxi.
692 The test was incorrectly comparing the target register
693 and the displacement offset. This was a time bomb bug,
694 that would trigger in code like:
697 if Rb0 == Rb1 && Rt0 == Rt1 && Im0 == Rt1, that is,
698 the wrong check was Im0 == Rt1, instead of the supposed
699 Im0 == Imm1 (that was what the code mean't to do). It
700 was removing the second stxi assuming it was redundantly
701 generated; as that is not uncommon pattern on
702 translators generating jit.
704 2015-02-02 Paulo Andrade <pcpa@gnu.org>
706 * configure.ac, include/lightning/jit_private.h,
707 lib/jit_aarch64.c, lib/jit_alpha.c, lib/jit_arm.c,
708 lib/jit_disasm.c, lib/jit_hppa.c, lib/jit_ia64.c,
709 lib/jit_mips.c, lib/jit_ppc.c, lib/jit_print.c,
710 lib/jit_s390.c, lib/jit_sparc.c, lib/jit_x86.c: Add a new
711 --enable-devel-disassembler option, that should be used
712 during development, or lightning debug. This option
713 intermixes previous jit_print and jit_disassemble
714 output, making it easier to visualize what lightning
715 call was used, and what code was generated.
717 2015-01-31 Paulo Andrade <pcpa@gnu.org>
719 * lib/jit_arm-cpu.c, lib/jit_arm.c: Only limit to 24 bit
720 displacement non conditional jump in the same jit_state_t.
722 2015-01-19 Paulo Andrade <pcpa@gnu.org>
724 * doc/body.texi: Reorder documentation, making jit_frame
725 and jit_tramp the lightning response to the need of
726 trampolines, continuations and tail call optimizations.
727 A pseudo code example of a factorial function was added.
728 Also added a section for description of the available
731 * doc/fact.c: New file, implementing a simple example of
732 a translation of a trivial, recursive, tail call optimization
733 into lightning calls. This is the conversion to functional C
734 code of the example in doc/body.texi.
736 * doc/Makefile.am: Update for the next test case.
738 2015-01-17 Paulo Andrade <pcpa@gnu.org>
740 * include/lightning.h, lib/jit_aarch64.c,
741 lib/jit_alpha.c, lib/jit_arm-vfp.c, lib/jit_arm.c,
742 lib/jit_hppa.c, lib/jit_ia64.c, lib/jit_mips.c,
743 lib/jit_ppc.c, lib/jit_s390.c, lib/jit_sparc.c,
744 lib/jit_x86.c: Add the new jit_arg_register_p predicate.
745 The predicate is expected to be used to know if an
746 argument is in a register, what would need special
747 handling if code that can overwrite non callee save
748 registers is executed.
750 * check/carg.c: New test case to check consistency and
751 expected usage of jit_arg_register_p.
753 * check/Makefile.am: Update for new test case.
755 2015-01-17 Paulo Andrade <pcpa@gnu.org>

769 lib/jit_ppc.c, lib/jit_s390.c,
770 lib/jit_sparc.c, lib/jit_x86.c: Remove jit_arg_reg_p and
771 jit_arg_f_reg_p from a public header, and define it only
772 on port specific files where an integer offset is used
773 to qualify an argument identifier. Exported code expects
774 an opaque pointer (but of jit_node_t* type) to "qualify"
775 an argument identifier.
776 This patch, and the code review/simplification done during
777 it also corrected some bugs:
778 o Inconsistent jit_arg_d value of double argument after 3
779 integer arguments in arm for jit_functions; tested, C
780 functions were being properly called.
781 o Inconsistent use of getarg_{f,d} and putarg*_{f,d} on
782 s390 (32-bit) that happened to not have a proper test
783 case, as it would only happen for jit functions, and
784 tested, called C functions had proper arguments.
785 o Corrected a "last minute" correction that did not go
786 to the committed version, and would not compile on hppa,
787 due to bad _jit_putargi_d prototype definition.
789 2015-01-17 Paulo Andrade <pcpa@gnu.org>
791 * doc/body.texi: Correct wrong/outdated information for
792 hton*, pusharg* and ret*, and add missing documentation
793 for rsb*, qmul*, qdvi* and putarg*.
795 2015-01-15 Paulo Andrade <pcpa@gnu.org>
797 * configure.ac, lib/jit_disasm.c: Rewrite workaround
798 to apparent problem to initialize powerpc disassembler.
800 2015-01-15 Paulo Andrade <pcpa@gnu.org>
802 * include/lightning.h, lib/jit_aarch64.c,

805 lib/jit_s390.c, lib/jit_sparc.c, lib/jit_x86.c:
806 Implement jit_putarg*. It works as a mix of jit_getarg*
807 and jit_pusharg*, in the way that the first argument is
808 a register or immediate, and the second is a pointer
809 returned by jit_arg*. The use of the interface is to change
810 values of arguments to the current jit function.
812 * check/put.ok, check/put.tst: New test cases exercising
813 the new jit_putarg* interface.
815 * check/Makefile.am, check/lightning.c: Update for the
816 new test case and interface.
818 2015-01-08 Paulo Andrade <pcpa@gnu.org>

825 include/lightning.h, include/lightning/Makefile.am,
826 lib/Makefile.am, lib/jit_s390.c, lib/jit_size.c,
827 lib/lightning.c: Update for renamed files.
829 2015-01-08 Paulo Andrade <pcpa@gnu.org>
831 * include/lightning.h, include/lightning/jit_private.h,
832 include/lightning/jit_s390x.h, lib/jit_disasm.c,
833 lib/jit_s390x-cpu.c, lib/jit_s390x-fpu.c, lib/jit_s390x-sz.c,
834 lib/jit_s390x.c, lib/jit_size.c, lib/lightning.c:
835 Add support for generating jit for s390 32 bit. This change
836 also removed %f15 from the list of temporaries fpr registers;
837 it was not being used, but if were, it would corrupt the
838 stack frame because the spill address would overwrite grp
841 2014-12-26 Paulo Andrade <pcpa@gnu.org>
843 * lib/jit_ppc-cpu.c, lib/jit_ppc.c: Correct some endianess issues
844 on the powerpc le backend.
846 2014-12-26 Paulo Andrade <pcpa@gnu.org>
848 * lib/jit_ppc-cpu.c: Add mcrxr instruction emulation,
849 as this instruction has been phased out, and should be
850 implemented as a kernel trap.
852 2014-12-26 Paulo Andrade <pcpa@gnu.org>
854 * lib/jit_arm.c: Better check for need to flush constants
855 before the pool being no longer reachable.
857 2014-12-25 Paulo Andrade <pcpa@gnu.org>
859 * include/lightning.h: Split jit_htonr in the new 3 interfaces
860 jit_htonr_us, jit_htonr_ui and jit_htonr_ul, the later only
861 available on 64 bit. The plain/untyped jit_htonr macro call
862 maps to the wordsize one.

879 2014-12-24 Paulo Andrade <pcpa@gnu.org>
881 * include/lightning/jit_private.h, include/lightning/jit_x86.h,
882 lib/jit_disasm.c, lib/jit_x86-cpu.c, lib/jit_x86-sse.c,
883 lib/jit_x86-sz.c, lib/jit_x86-x87.c, lib/jit_x86.c,
884 size.c: Implement support for the x32 abi. Built and
885 tested on Gentoo default/linux/amd64/13.0/x32 profile.
887 2014-12-24 Paulo Andrade <pcpa@gnu.org>
889 * lib/jit_names.c: Add missing rsbi_f and rsbi_d strings.
891 2014-12-21 Paulo Andrade <pcpa@gnu.org>
893 * lib/jit_arm.c: Call __clear_cache for every page.
894 This should only be required for older boards or
895 toolchain setup, but has been reported to be required
896 for lightning at some point.
898 2014-12-21 Paulo Andrade <pcpa@gnu.org>
900 * lib/jit_arm.c: Correct check to guard overflow of index
901 of constants from program counter.
903 2014-11-24 Paulo Andrade <pcpa@gnu.org>
905 * lib/lightning.c: Remove an optimization to calee save
906 registers that may incorrectly remove a jit_movr under
909 2014-11-20 Paulo Andrade <pcpa@gnu.org>
911 * include/lightning/jit_ppc.h, lib/jit_ppc-cpu.c,
912 lib/jit_ppc.c: Add initial powerpc le support.
914 2014-11-20 Paulo Andrade <pcpa@gnu.org>
916 * lib/jit_disasm.c: Change thumb or arm disassemble based on
917 jit code before disassembly.
919 * lib/jit_arm-cpu.c: Correct reversed arguments to LDRD and
920 STRD instructions, and correct checking for support of those.
922 * lib/jit_arm-swf.c: Correct wrong use of LDRD and STRD and
923 only use those if the register is even.
925 * check/check.arm.swf.sh, check/check.arm4.swf.sh: New files
926 to test LDRD and STRD, as well as the alternate code path
927 when those are not available, in the .arm4. test case.
929 * check/Makefile.am: Update for the new test cases.
931 2014-11-08 Paulo Andrade <pcpa@gnu.org>

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

962 lib/jit_s390x.c, lib/jit_sparc.c, lib/jit_x86.c: Add an
963 assertion to all code generation "drivers" to ensure
964 _jitc->regarg is empty or in an expected state, after
965 translation of a lightning instruction to native code.
966 This change was a brute force test to find out other cases
967 of a temporary not being release (like was happening with
968 _bmsi and _bmci on x86), but no other case was found,
969 after running make check, with assertions enabled, on all

979 * lib/jit_disasm.c: Do not cause an fatal error if init_jit
980 fails in the jit_init_debug call.
982 2014-10-24 Paulo Andrade <pcpa@gnu.org>
984 * lib/jit_ia64.c, lib/jit_ppc.c: Correct handling of function
985 descriptor when first prolog is a jit_tramp prolog. The
986 test case was using the same jit_context_t, so was not
987 triggering this condition.
989 * lib/jit_ppc-cpu.c: Properly handle jump displacements that
990 do not fit on 24 powerpc. This required changing from previous
991 "mtlr reg, blr" to "mtctr reg, bctr" to properly handle
992 the logic to "hide" function descriptors, but that would
993 also be required as the proper jit_jmpr when/if implementing
994 optimizations to leaf functions (was working with blr because
995 it is saved/reloaded in prolog/epilog).
997 2014-10-21 Paulo Andrade <pcpa@gnu.org>
999 * include/lightning.h, lib/lightning.c: Add three predicates
1000 to query information about labels. jit_forward_p(label)
1001 will return non zero if the label is "forward", that is
1002 need a call to jit_link(label), jit_indirect_p(label)
1003 that returns non zero if the label was created with the
1004 jit_indirect() call, and jit_target_p(label) that will
1005 return non zero if there is at least one jump patched
1006 to land at that label.
1008 2014-10-18 Paulo Andrade <pcpa@gnu.org>
1010 * check/range.ok, check/range.tst: New test case designed
1011 to catch incorrect code generation, usually due to incorrect
1012 test of immediate size. The test checks a large amount of
1013 encodings in "power of two" boundaries. This test exorcises
1014 a significant amount of code paths that was previously not
1017 * check/Makefile.am: Add range test to make check target.
1019 * lib/jit_aarch64-cpu.c: Correct wrong address calculation
1020 for stxi_c, stxi_s, stxi_i and stxi_l when the offset is
1023 * lib/jit_mips-fpu.c: Correct wrong size test to check if
1024 an immediate can be encoded in a float or double store.
1026 * lib/jit_s390x-cpu.c: Correct inverted encoding to stxi_s
1027 when the offset cannot be encoded, and fallbacks to an
1028 alternate encoding in 2 instructions.
1030 2014-10-17 Paulo Andrade <pcpa@gnu.org>
1032 * check/alu_rsb.ok, check/alu_rsb.tst: New files implementing
1035 * check/Makefile.am, check/lightning.c, include/lightning.h,
1036 lib/jit_aarch64-cpu.c, lib/jit_aarch64-fpu.c, lib/jit_aarch64-sz.c,
1037 lib/jit_aarch64.c, lib/jit_alpha-cpu.c, lib/jit_alpha-fpu.c,
1038 lib/jit_alpha-sz.c, lib/jit_alpha.c, lib/jit_arm-cpu.c,
1039 lib/jit_arm-swf.c, lib/jit_arm-sz.c, lib/jit_arm-vfp.c,
1040 lib/jit_arm.c, lib/jit_hppa-cpu.c, lib/jit_hppa-fpu.c,
1041 lib/jit_hppa-sz.c, lib/jit_hppa.c, lib/jit_ia64-cpu.c,
1042 lib/jit_ia64-fpu.c, lib/jit_ia64-sz.c, lib/jit_ia64.c,
1043 lib/jit_mips-cpu.c, lib/jit_mips-fpu.c, lib/jit_mips-sz.c,
1044 lib/jit_mips.c, lib/jit_names.c, lib/jit_ppc-cpu.c,
1045 lib/jit_ppc-fpu.c, lib/jit_ppc-sz.c, lib/jit_ppc.c,
1046 lib/jit_s390x-cpu.c, lib/jit_s390x-fpu.c, lib/jit_s390x-sz.c,
1047 lib/jit_s390x.c, lib/jit_sparc-cpu.c, lib/jit_sparc-fpu.c,
1048 lib/jit_sparc-sz.c, lib/jit_sparc.c, lib/jit_x86-cpu.c,
1049 lib/jit_x86-sse.c, lib/jit_x86-sz.c, lib/jit_x86-x87.c,
1050 lib/jit_x86.c, lib/lightning.c: Implement jit_rsb*. This
1051 was a missing lightning 1.x interface, that on most
1052 backends is synthesized, but on a few backends (hppa and ia64),
1053 it can generate better code as on those there is, or the
1054 only instruction with an immediate is in "rsb" format
1057 2014-10-17 Paulo Andrade <pcpa@gnu.org>
1059 * lib/jit_names.c: New file with single definition of string
1060 representation of lightning IR codes.
1062 * size.c: Modified to append the code name in a C comment
1063 after the maximum instruction size.
1065 * lib/jit_print.c: Minor change to not duplicate jit_names.c
1068 * lib/jit_aarch64-sz.c, lib/jit_alpha-sz.c, lib/jit_arm-sz.c,
1069 lib/jit_hppa-sz.c, lib/jit_ia64-sz.c, lib/jit_mips-sz.c,
1070 lib/jit_ppc-sz.c, lib/jit_s390x-sz.c, lib/jit_sparc-sz.c,
1071 lib/jit_x86-sz.c: Rewritten to add string representation of
1072 IR codes in a C comment.
1074 2014-10-14 Paulo Andrade <pcpa@gnu.org>
1076 * lib/jit_aarch64-cpu.c, lib/jit_alpha-cpu.c, lib/jit_arm-cpu.c,
1077 lib/jit_hppa-cpu.c, lib/jit_mips-cpu.c, lib/jit_ppc-cpu.c,
1078 lib/jit_sparc-cpu.c: Implement or correct the internal
1079 nop(count) call that receives an argument that tells the
1080 modulo bytes to align the code for the next instruction.
1082 * include/lightning.h, lib/lightning.c, lib/jit_aarch64.c,
1083 lib/jit_alpha.c, lib/jit_arm.c, lib/jit_hppa.c, lib/jit_ia64.c,
1084 lib/jit_mips.c, lib/jit_ppc.c, lib/jit_s390x.c, lib/jit_sparc.c,
1085 lib/jit_x86.c: Implement the new jit_align() call that receive
1086 an argument, that tells the modulo, in bytes, to align the
1087 next instruction. In most backends the only value that makes
1088 a difference is a value that matches sizeof(void*), as all
1089 other values usually are already automatically aligned in
1090 labels, but not guaranteed to be aligned at word size bytes.
1092 * check/align.ok, check/align.tst: New files, implementing
1093 a simple test for the new jit_align() interface.
1095 * check/Makefile.am, check/lightning.c, lib/jit_aarch64-sz.c,
1096 lib/jit_alpha-sz.c, lib/jit_arm-sz.c, lib/jit_hppa-sz.c,
1097 lib/jit_ia64-sz.c, lib/jit_mips-sz.c, lib/jit_ppc-sz.c,
1098 lib/jit_print.c, lib/jit_s390x-sz.c, lib/jit_sparc-sz.c,
1099 lib/jit_x86-sz.c: Update for the new jit_code_align code and
1100 the jit_align() interface.
1102 2014-10-13 Paulo Andrade <pcpa@gnu.org>
1104 * include/lightning.h, lib/jit_size.c, size.c: Use a
1105 symbolic value for the last IR code.
1107 2014-10-12 Paulo Andrade <pcpa@gnu.org>
1109 * include/lightning.h, include/lightning/jit_private.h,
1110 lib/jit_aarch64-cpu.c, lib/jit_alpha-cpu.c, lib/jit_arm-cpu.c,
1111 lib/jit_hppa-cpu.c, lib/jit_ia64-cpu.c, lib/jit_mips-cpu.c,
1112 lib/jit_ppc-cpu.c, lib/jit_s390x-cpu.c, lib/jit_sparc-cpu.c,
1113 lib/jit_x86-cpu.c, lib/lightning.c: Implement the new
1114 jit_frame and jit_tramp interfaces, that allow writing
1115 trampoline like calls, where a single dispatcher jit buffer
1116 is written, and later other jit buffers are created, with
1117 the same stack frame layout as the dispatcher. This is the
1118 logic that GNU Smalltalk used in lightning 1.x, and is required
1119 to make a sane port for lighting 2.x.
1121 * jit_ia64-cpu.c: Implement support for jit_frame and jit_tramp,
1122 and also correct wrong encoding for B4 instructions, that
1123 implement jmpr, as well as correct reverse logic in _jmpr,
1124 that was moving the branch register to the jump register,
1126 Also, if a stack frame is to be assumed, always assume it may
1127 call a function with up to 8 arguments, regardless of the
1128 hint frame argument.
1130 * lib/jit_arm.c: Add a new must_align_p() interface to ensure
1131 function prologs are always aligned. This condition was
1132 previously always true, somewhat by accident, but with
1133 jit_tramp it is not guaranteed.
1135 * jit_ia64-cpu.c: lib/jit_ppc.c: Add minor special handling
1136 required to implement jit_tramp, where a function descriptor
1137 should not be added before a prolog, as jit_tramp means omit
1140 * check/lightning.c: Update test driver for the new interfaces.
1142 * check/Makefile.am, check/tramp.tst, check/tramp.ok: Add
1143 a simple test and example of the jit_frame and jit_tramp
1144 usage implementing a simple Fibonacci function using a
1145 simulation of an interpreter stack and how it would handle
1146 state in language specific variables.
1148 * doc/body.texi: Add documentation for jit_frame and
1151 2014-09-29 Paulo Andrade <pcpa@gnu.org>
1153 * lib/jit_aarch64.c, lib/jit_alpha.c, lib/jit_arm.c,
1154 lib/jit_hppa.c, lib/jit_ia64.c, lib/jit_mips.c,
1155 lib/jit_ppc.c, lib/jit_s390x.c, lib/jit_sparc.c,
1156 lib/jit_x86.c, lib/lightning.c: Allow jit_jmpi on a
1157 target that is not a node. This may lead to hard to
1158 debug code generation, but is a required feature for
1159 certain generators, like the ones that used lightning
1160 1.2x. Note that previously, but not really well
1161 documented, it was instructed to use:
1162 jit_movi(rn, addr); jit_jmpr(rn);
1164 jit_patch_abs(jit_jmpi(), addr);
1167 2014-09-24 Paulo Andrade <pcpa@gnu.org>
1169 * lib/jit_x86-sz.c: Generate information about instruction
1170 lengths for more precise calculation of buffer size on
1171 Windows x64. This change is specially important because
1172 the maximum instruction length is larger than other
1173 systems, what could cause an out of bounds write on
1174 special conditions without this update.
1176 2014-09-24 Paulo Andrade <pcpa@gnu.org>
1178 * check/lightning.c: Add workaround to conflicting global
1179 optind variable in cygwin binutils that have an internal
1180 getopt* implementation.
1182 * lib/jit_x86-cpu.c: Add a simple define ffsl ffs if building
1183 for 32 bit and there is no ffsl function.
1185 2014-09-24 Paulo Andrade <pcpa@gnu.org>
1187 * check/lightning.c: Add a hopefully temporary kludge to not use
1188 sprintf and sscanf returned by dlsym. This is required to pass
1191 * include/lightning/jit_private.h: Use symbolic name for first
1192 integer register argument, as this is different in sysv and
1195 * include/lightning/jit_x86.h: Add conditionals and definitions
1196 for Windows x64 (under __CYGWIN__ preprocessor conditional).
1198 * lib/jit_x86-cpu.c: Correct one instruction encoding bug, that
1199 was working by accident. Only use rax to rdx for some byte
1200 operations to work on compatibility mode (that is, to generate
1201 the proper encoding, instead of actually generating encoding
1202 for high byte registers, e.g. %bh).
1203 Add proper prolog and epilog for windows x64.
1205 * lib/jit_x86-sse.c: Correct a swapped rex prefix for float
1208 * lib/jit_x86.c: Adjust to support Windows x64 abi.
1210 * check/check.x87.nodata.sh: New file, previously used but that
1213 2014-09-07 Paulo Andrade <pcpa@gnu.org>
1215 * lib/lightning.c: Mark all registers advertised as live, as
1216 per jit_callee_save_p as live whenever reaching a jump that
1217 cannot be tracked. This is a rethink of the previous commit,
1218 and is a better approach, otherwise there would not be much
1219 sense on relying on jit_callee_save_p if it could not be
1222 * check/jmpr.tst, check/jmpr.ok: New files implementing a very
1223 simple test case, that would actually cause an assertion on
1224 code before the change to only mark as live when reaching a
1225 jump that could not tracked, the actually advertised as callee
1228 check/Makefile.am: Update for new jmpr test case.
1230 2014-09-01 Paulo Andrade <pcpa@gnu.org>
1232 * lib/lightning.c: Do not mark all registers in unknown state
1233 as live on jit_jmpr, or jit_jmpi to an absolute address. Instead,
1234 treat it as a function call, and only consider JIT_Vn registers
1237 2014-08-29 Paulo Andrade <pcpa@gnu.org>
1239 * doc/body.texi: Add a proper info menu entry for
1242 * doc/version.texi: Regenerate.
1244 2014-08-16 Paulo Andrade <pcpa@gnu.org>
1246 * lib/jit_aarch64-cpu.c, lib/jit_aarch64-fpu.c,
1247 lib/jit_arm-cpu.c, lib/jit_arm-vfp.c,
1248 lib/jit_hppa-cpu.c, lib/jit_hppa-fpu.c,
1249 lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c,
1250 lib/jit_mips-cpu.c, lib/jit_mips-fpu.c,

1254 lib/jit_x86-cpu.c, lib/jit_x86-sse.c,
1255 lib/jit_x86-x87.c: Review generation of all branch
1256 instructions and always adds the jit_class_nospill
1257 bitfield for temporary registers that cannot be spilled
1258 because the reload would be after a conditional jump; the
1259 patch only adds an extra assertion. These conditions do
1260 not happen on documented lightning usage, but can happen
1261 if one uses the not exported jit_get_reg and jit_unget_reg
1262 calls and cause enough register starvation.
1264 2014-08-16 Paulo Andrade <pcpa@gnu.org>
1266 * lib/jit_alpha.c: Correct wrong bitmask of most argument
1267 float register arguments, that were being set as callee
1268 save instead of argument registers class.
1270 2014-08-16 Paulo Andrade <pcpa@gnu.org>
1272 * lib/jit_arm-sz.c: Regenerate table of known maximum
1273 instruction sizes for the software float fallback,
1274 that implements "virtual" float registers in the stack
1275 and operations as calls to libgcc.
1277 * size.c: Correct typo in the generated jit_arm-sz.c file.
1279 2014-08-10 Paulo Andrade <pcpa@gnu.org>
1281 * include/lightning/jit_alpha.h, lib/jit_alpha-cpu.c,
1282 lib/jit_alpha-fpu.c, lib/jit_alpha-sz.c, lib/jit_alpha.c:
1283 New files implementing a lightning Alpha port. Thanks
1284 to Trent Nelson and snakebit.net staff for providing access
1287 * check/float.tst, check/lightning.c, configure.ac,
1288 include/lightning.h, include/lightning/Makefile.am,
1289 include/lightning/jit_private.h, lib/Makefile.am,
1290 lib/jit_disasm.c, lib/jit_size.c, lib/lightning.c:
1291 Minor changes to adapt for the new Alpha port.
1293 2014-08-10 Paulo Andrade <pcpa@gnu.org>
1295 * lib/lightning.c: Always mark JIT_RET and JIT_FRET as
1296 live in a function epilog. This is required because
1297 on some ports a complex sequence, allocating one or more
1298 registers, may be required to jump from a ret* to the
1299 epilog, and the lightning api does not have annotations
1300 to know if a function returns a value, or the type of
1303 2014-08-10 Paulo Andrade <pcpa@gnu.org>
1305 * lib/lightning.c: Change the correct live bitmask of
1306 return registers after a function call in jit_update.
1308 2014-08-10 Paulo Andrade <pcpa@gnu.org>
1310 * lib/lightning.c: Change assertions to have an int
1311 result and correct a bad bit mask assertion.
1313 2014-08-10 Paulo Andrade <pcpa@gnu.org>
1315 * lib/jit_aarch64.c: Correct bad setup for assertion
1316 of consistency before a patch.
1318 2014-08-10 Paulo Andrade <pcpa@gnu.org>
1320 * lib/jit_mips-cpu.c: Correct typo in the jit_bmsr
1321 implementation that was using the wrong test result
1324 2014-07-28 Paulo Andrade <pcpa@gnu.org>
1326 * lib/jit_memory.c: Do not call free on NULL pointers.
1328 * include/lightning/jit_private.h, lib/jit_note.c,
1329 lib/lightning.c: Add a wrapper to memcpy and memmove
1330 to not actually call those functions with a zero size
1331 argument, and likely also a null src or dst.
1333 2014-07-27 Paulo Andrade <pcpa@gnu.org>
1335 * include/lightning/jit_private.h, lib/jit_disasm.c,
1336 lib/lightning.c: Remove the global jit_progname variable.
1337 It was being only used in jit_init_debug, that is called
1338 from init_jit, so, just pass an argument.
1340 2014-07-27 Paulo Andrade <pcpa@gnu.org>
1342 * doc/body.texi: Add note that jit_set_memory_functions
1343 should be called before init_jit, because init_jit
1344 itself may call the memory wrappers.
1346 2014-04-22 Paulo Andrade <pcpa@gnu.org>
1348 * lib/jit_arm.c: Do not get confused with default settings
1349 if /proc is not mounted on Linux specific code path.
1351 2014-04-09 Paulo Andrade <pcpa@gnu.org>
1353 * include/lightning/jit_aarch64.h, include/lightning/jit_arm.h,
1354 include/lightning/jit_hppa.h, include/lightning/jit_ia64.h,
1355 include/lightning/jit_mips.h, include/lightning/jit_ppc.h,
1356 include/lightning/jit_private.h, include/lightning/jit_s390x.h,
1357 include/lightning/jit_sparc.h, include/lightning/jit_x86.h:
1358 Do not add jit_regset_t, JIT_RA0, and JIT_FA0 to the installed
1359 header file. These types and definitions are supposed to be
1360 only used internally.
1362 2014-04-05 Paulo Andrade <pcpa@gnu.org>
1364 * lib/jit_arm-cpu.c: Only adjust stack pointer in prolog if
1365 need stack space, that is, do not emit a nop instruction
1366 subtracting zero from the stack pointer.
1368 2014-04-04 Paulo Andrade <pcpa@gnu.org>
1370 * lib/jit_disasm.c: Correct a crash in the doc/printf example
1371 on arm due to releasing the data_info information in
1372 jit_clear_state. This is a special case for arm only, and
1373 actually, only armv5 or older uses the data_info buffer,
1374 or when forcing arm instruction set mode besides thumb
1377 2014-12-03 Paulo Andrade <pcpa@gnu.org>
1379 * doc/body.texi: Write detailed description and examples for
1380 jit_get_memory_functions, jit_set_memory_functions,
1381 jit_get_code, jit_set_code, jit_get_data and jit_set_data.
1383 2014-12-03 Paulo Andrade <pcpa@gnu.org>
1385 * include/lightning.h, include/lightning/jit_private.h,
1386 lib/lightning.c: Implement the new jit_set_data() interface,
1387 and the new jit_get_data() helper. Like jit_set_code(),
1388 jit_realize() should be called before jit_set_data().
1389 The most common usage should be jit_set_data(JIT_DISABLE_DATA
1390 | JIT_DISABLE_NOTE), to force synthesize any float/double
1391 constant in the stack and not generate any debug information.
1393 * lib/jit_note.c: Minor change to debug note generation as
1394 now it uses an alternate temporary data buffer during constants
1395 and debug generation to accommodate the possibility of the user
1396 setting an alternate data buffer.
1398 * lib/jit_hppa-fpu.c, lib/jit_s390x.c, lib/jit_s390x-cpu.c,
1399 lib/jit_s390x-fpu.c, lib/jit_sparc.c, lib/jit_sparc-fpu.c,
1400 lib/jit_x86-sse.c, lib/jit_x86-x87.c: Implement jit_set_data.
1402 * lib/jit_hppa-sz.c, lib/jit_sparc-sz.c, lib/jit_x86-sz.c,
1403 lib/jit_s390x-sz.c: Update for several instructions that now
1404 have a different maximum length due to jit_set_data.
1406 * lib/jit_mips-fpu.c: Implement jit_set_data, but missing
1407 validation on n32 and n64 abis (and/or big endian).
1409 * lib/jit_mips-sz.c: Update for changes in o32.
1411 * lib/jit_ppc-fpu.c: Implement jit_set_data, but missing
1412 validation on Darwin PPC.
1414 * lib/jit_ppc-sz.c: Update for changes in powerpc 32 and
1417 * lib/jit_ia64-fpu.c: Implement untested jit_set_data.
1419 * TODO: Add note to list ports that were not tested for the
1420 new jit_set_data() feature, due to no longer having access
1423 * check/nodata.c: New file implementing a simple test exercising
1424 several different conditions created by jit_set_data().
1426 * check/check.nodata.sh: New file implementing a wrapper
1427 over the existing *.tst files, that runs all tests without
1428 using a data buffer for constants; only meaningful (and
1429 enabled) on architectures that used to store float/double
1430 constants on a read only data buffer.
1432 * configure.ac, check/Makefile.am: Update for the new test
1435 * check/lightning.c: Implement the new "-d" option that
1436 sets an internal flag to call jit_set_data() disable
1437 constants and debug, that is, using only a pure code
1440 2014-11-03 Paulo Andrade <pcpa@gnu.org>
1442 * include/lightning.h, include/lightning/jit_private.h,
1443 lib/lightning.c: Implement the new jit_set_code() interface,
1444 that allows instructing lightning to use an alternate code
1445 buffer. The new jit_realize() function should be called
1446 before jit_set_code(), and usually call jit_get_code()
1447 to query the amount of bytes expected to be required for
1450 * lib/jit_size.c: Minor update to have less chances of
1451 miscalculating the code buffer by starting the counter
1452 with the size of the longest instruction instead of zero,
1453 as code emit fails if at any moment less than the longest
1454 instruction bytes are available.
1456 * check/setcode.c: New file implementing some basic tests
1457 of the new jit_set_code() interface.
1459 * check/Makefile.am: Update for newer test case.
1461 2014-06-03 Paulo Andrade <pcpa@gnu.org>
1463 * include/lightning.h, lib/lightning.c: Add the new
1464 jit_indirect() call, that returns a special label node,
1465 and tells lightning that the label may be the target of
1468 * doc/body.texi: Document the new jit_indirect() call, and
1469 add examples of different ways to create labels and branches.
1471 2014-23-02 Paulo Andrade <pcpa@gnu.org>
1473 * lib/jit_x86.c: Rewrite previous patch to inline save/restore
1474 because clobbering %ebx in x86 is treated as an error
1475 (jit_x86.c:239:5: error: PIC register clobbered by 'ebx' in 'asm').
1477 2014-19-02 Paulo Andrade <pcpa@gnu.org>
1479 * lib/jit_x86.c: Rewrite incorrect inline assembly that could
1480 truncate a variable in a callee save register. Now it simply
1481 tells gcc that the register is clobbered, instead of using a
1482 *32 bit* swap with a temporary variable. The problem only
1483 happens when compiling with optimization.
1485 2014-19-02 Paulo Andrade <pcpa@gnu.org>
1487 * include/lightning/jit_aarch64.h, include/lightning/jit_arm.h,
1488 include/lightning/jit_hppa.h, include/lightning/jit_ia64.h,
1489 include/lightning/jit_mips.h, include/lightning/jit_ppc.h,
1490 include/lightning/jit_s390x.h, include/lightning/jit_sparc.h,
1491 include/lightning/jit_x86.h: Change jit_regset_t to an
1492 unsigned type, to allow safe right shift.
1494 * lib/lightning.c: Rewrite jit_regset_scan1 to allow easier
1495 compiler optimization.
1497 2013-12-03 Paulo Andrade <pcpa@gnu.org>
1499 * lib/jit_x86-x87.c: Correct wrong optimization when
1500 loading the log(2) constant.
1502 2013-12-03 Paulo Andrade <pcpa@gnu.org>
1504 * lib/jit_x86-cpu.c: Use the emms instruction before
1505 calling any function. This is particularly important
1506 when using c99 complex functions as it can easily
1507 overflow the x87 stack due to the way lightning uses
1508 the x87 stack as a flat register file.
1510 2013-12-02 Paulo Andrade <pcpa@gnu.org>
1512 * lib/jit_x86-x87.c: Correct wrong code generation due
1513 to comparing the base and not the value register with
1516 2013-12-02 Paulo Andrade <pcpa@gnu.org>
1518 * lib/jit_x86-x87.c, lib/jit_x86.c: Use 8 bytes aligned
1519 stack offset for float/double x87 to/from sse move.
1521 2013-11-27 Paulo Andrade <pcpa@gnu.org>
1523 * configure.ac, lib/jit_arm-swf.c, lib/jit_arm.c: Add
1524 changes that should at least allow building lightning
1527 2013-10-08 Paulo Andrade <pcpa@gnu.org>
1529 * lib/jit_ppc-cpu.c: Correct wrong shortcut for ldxi_l with
1530 a zero offset, that was calling ldr_i instead of ldr_l.
1532 2013-10-08 Paulo Andrade <pcpa@gnu.org>
1534 * include/lightning/jit_arm.h, lib/jit_arm-cpu.c: Do not use
1535 by default load/store instructions that map to ldrt/strt.
1536 There is already the long displacement version for positive
1537 offsets, and when using a (shorter) negative offset it does
1538 not map to ldrt/strt. At least on qemu strt may cause
1539 reproducible, but unexpected SIGILL.
1541 2013-10-08 Paulo Andrade <pcpa@gnu.org>
1543 * lib/jit_arm-vfp.c: Correct wrong load/store offset
1544 calculation when the displacement is constant but too
1545 large to use an instruction with an immediate offset.
1547 2013-10-07 Paulo Andrade <pcpa@gnu.org>
1549 * check/self.c: Extend tests to validate jit_callee_save_p
1550 does not cause an assertion on valid arguments, and test
1551 extra registers defined on some backends.
1553 * configure.ac: Do not ignore environment CFLAGS when
1554 checking if need to test runtime configurable options,
1555 like use x87 when sse2 is available, arm instruction set
1556 instead of thumb, etc.
1558 * include/lightning/jit_arm.h: Correct wrong jit_f macro
1561 * include/lightning/jit_ia64.h, include/lightning/jit_ppc.h:
1562 Correct wrong jit_r macro definition.
1564 * lib/jit_x86-x87.c, lib/jit_x86.c: Actually use the
1565 reserved stack space for integer to/from float conversion.
1566 The stack space was also changed to ensure it is 8 bytes
1567 aligned. Also, for Solaris x86 in 32 bit mode, an alternate
1568 truncr_d was implemented because for some reason it is
1569 failing with SIGILL if using the "fisttpl" instructions,
1570 that must be available on p6 or newer, but for the sake of
1571 making all tests pass, implement a 486 or newer sequence
1572 if "sun" is defined.
1574 2013-10-03 Paulo Andrade <pcpa@gnu.org>
1576 * include/lightning/jit_mips.h, lib/jit_mips-cpu.c,
1577 lib/jit_mips-sz.c, lib/jit_mips.c, size: Build and
1578 pass all test cases on Irix big endian mips using
1581 2013-10-02 Paulo Andrade <pcpa@gnu.org>
1583 * include/lightning/jit_mips.h: Add proper mips abi detection.
1585 2013-09-30 Paulo Andrade <pcpa@gnu.org>
1587 * lib/jit_print.c: Do not crash if calling jit_print from
1588 gdb before actually emitting code.
1590 * lib/lightning.c: Correct misplaced check for already
1591 visited blocks on conditional branches, what was preventing
1592 proper merge live bit masks of forward blocks.
1594 2013-09-30 Paulo Andrade <pcpa@gnu.org>
1596 * lib/jit_x86-cpu.c: Correct not properly tested case of using
1597 %r12 as index register, what was causing an invalid assertion.
1598 %r12 is mapped to the "extra" JIT_R3 register, and test cases
1599 only test "standard" lightning registers.
1601 2013-09-28 Paulo Andrade <pcpa@gnu.org>
1603 * lib/jit_ia64.c: Minor change to force collecting the maximum
1604 instruction length in the --enable-devel-get-jit-size build
1605 mode. The actual generated file did not change because the
1606 sampling was large enough that it had already collected proper
1607 information in the previously slightly buggy code (not forcing
1608 a sync of the instructions that could be combined).
1610 2013-09-27 Paulo Andrade <pcpa@gnu.org>
1612 * lib/jit_arm.c: Correct build when disassembler is
1615 2013-09-25 Paulo Andrade <pcpa@gnu.org>
1617 * lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c: Correct some
1618 off by one range checks (that were only accepting values
1619 one less than the maximum allowed) and an invalid test
1620 condition check that was forcing it to always use
1621 indirect jumps even when reachable with an immediate
1624 2013-09-24 Paulo Andrade <pcpa@gnu.org>
1626 * lib/jit_aarch64-sz.c, lib/jit_arm-sz.c, lib/jit_hppa-sz.c,
1627 lib/jit_ia64-sz.c, lib/jit_mips-sz.c, lib/jit_ppc-sz.c,
1628 lib/jit_s390x-sz.c, lib/jit_size.c, lib/jit_sparc-sz.c,
1629 lib/jit_x86-sz.c: New files implementing static tables
1630 with longest known instructions length generated to match
1631 a lightning instruction. These tables should make it easier
1632 to make it very unlikely to ever miscalculate, or by too
1633 much, the size of a code buffer.
1635 * lib/jit_size.c: New file that aids to either collect
1636 jit code size information, or use the information depending
1639 * size.c: New helper file that parses input for, and create
1640 an initial jit_$arch-sz.c file, that needs some minor edit
1641 for arches with multiple configurations.
1643 * configure.ac, Makefile.am: Add the new, devel mode only
1644 --enable-devel-get-jit-size configure option, that sets
1645 compile time flags to collect jit code size information,
1646 that will be used as input for the "noinst size program".
1648 * lib/jit_aarch64.c, lib/jit_arm.c, lib/jit_disasm.c,
1649 lib/jit_hppa.c, lib/jit_ia64.c, lib/jit_memory.c,
1650 lib/jit_mips.c, lib/jit_ppc.c, lib/jit_s390x.c,
1651 lib/jit_sparc.c, lib/jit_x86.c, lib/lightning.c: Minor
1652 changes for the --enable-devel-get-jit-size build mode,
1653 as well as the "production build mode" with jit code
1656 2013-09-14 Paulo Andrade <pcpa@gnu.org>
1658 * include/lightning.h, lib/lightning.c: Add the new
1659 jit_pointer_p interface, that returns a boolean value
1660 telling if the pointer argument is inside the jit
1661 code buffer. This is useful to avoid the need to add
1662 extra labels and calls to jit_address to figure bounds
1663 of code buffer, and still keep internal data private.
1665 2013-09-13 Paulo Andrade <pcpa@gnu.org>
1667 * include/lightning.h, include/lightning/jit_private.h,
1668 lib/jit_note.c: Change the code argument of jit_get_note
1669 to a jit_pointer_t and make jit_get_note a public interface.
1670 It was intended so since start, as a way to map an offset
1671 in the code to a function name, file name and line number
1674 2013-09-11 Paulo Andrade <pcpa@gnu.org>
1676 * doc/body.texi: Correct reversed arguments in example of
1677 usage in a (possibly) multi threaded, multiple jit_state_t
1680 * include/lightning/jit_arm.h, include/lightning/jit_private.h,
1681 lib/jit_arm-cpu.c, lib/jit_arm.c: Make a previously, non
1682 documented, global state private to the related jit_state_t
1685 2013-09-10 Paulo Andrade <pcpa@gnu.org>
1687 * check/self.c, check/self.ok: New files implementing simple
1688 consistency check assertions. At first validating some macros
1689 that use values from different sources agree.
1691 * check/Makefile.am: Update for the new test case.
1693 * include/lightning.h, lib/lightning.c: Add the new
1694 jit_callee_save_p() call, that is intended to be used when
1695 writing complex code using lightning, so that one does not
1696 need to verify what backend is being used, or have access to
1697 private data, to query if a register is callee save or not;
1698 on several backends the scratch registers are actually callee
1701 * include/lightning/jit_aarch64.h, include/lightning/jit_arm.h,
1702 include/lightning/jit_hppa.h, include/lightning/jit_mips.h,
1703 include/lightning/jit_ppc.h, include/lightning/jit_sparc.h,
1704 include/lightning/jit_x86.h: Add an explicit definition for
1705 JIT_R3-JIT_Rn, JIT_V3-JIT_Vn and JIT_F6-JIT_Fn when applicable.
1706 This allows one to write code based on "#if defined(JIT_XN)"
1707 and therefore, not need to check what is the current backend
1708 or have access to private data structures. This is particularly
1709 useful when writing virtual machines with several specialized,
1712 * lib/jit_ia64.c: Properly flag the callee save general
1713 purpose registers as such, so that jit_callee_save_p() works
1716 2013-09-10 Paulo Andrade <pcpa@gnu.org>
1718 * check/lightning.c, configure.ac: Conditionally use the
1719 code written to workaround a bug in the Hercules emulator,
1720 as isnan and isinf are not available at least on HP-UX ia64.
1722 2013-09-10 Paulo Andrade <pcpa@gnu.org>
1724 * lib/jit_s390x-cpu.c: Spill/reload correct callee save
1727 2013-09-10 Paulo Andrade <pcpa@gnu.org>
1729 * lib/jit_hppa-cpu.c: Correct code to call a function stored
1730 in a register or a patched function address.
1732 2013-09-10 Paulo Andrade <pcpa@gnu.org>
1734 * lib/jit_ia64-cpu.c: Correct incorrect logic when restoring
1735 the value of the "r2" callee save register.
1737 2013-08-29 Paulo Andrade <pcpa@gnu.org>
1739 * lib/jit_arm-cpu.c, lib/jit_arm.c: Correct wrong test and update
1740 of the thumb offset information, when checking if needing to
1741 patch a jump from arm to thumb mode. The problem would happen when
1742 remapping the code buffer, and the new address being lower than
1745 2013-08-26 Paulo Andrade <pcpa@gnu.org>
1747 * configure.ac: Extend FreeBSD test to also handle NetBSD.
1749 * lib/jit_x86-cpu.c: Correct wrongly defined offset type of
1750 ldxi_ui. Problem detected when building on NetBSD.
1752 * lib/lightning.c: Adjust code to handle NetBSD mremap,
1753 where arguments do not match Linux mremap.
1755 2013-08-26 Paulo Andrade <pcpa@gnu.org>
1757 * lib/jit_ppc.c: Correct C sequence point problem miscalculating
1758 the actual function address in a function descriptor. Problem
1759 happens with gcc 4.8.1 at least.
1761 2013-08-11 Paulo Andrade <pcpa@gnu.org>
1763 * lib/jit_s390x-cpu.c: Correct code checking if immediate
1764 fits instruction, but using the negated value.
1766 2013-07-28 Paulo Andrade <pcpa@gnu.org>
1768 * include/lightning/jit_s390x.h, lib/jit_s390x-cpu.c,
1769 lib/jit_s390x-fpu.c, lib/jit_s390x.c: New files
1770 implementing the new s390x port.
1772 * configure.ac, include/lightning.h,
1773 include/lightning/Makefile.am,
1774 include/lightning/jit_private.h,
1775 lib/Makefile.am, lib/jit_disasm.c, lib/lightning.c:
1776 Minor adaptation for the new s390x backend.
1778 * check/float.tst: Update for the s390x result of
1779 truncating +Inf to integer.
1781 * check/qalu_mul.tst: Add extra test cases to better test
1782 high word of signed multiplication as the result is
1783 adjust from unsigned multiplication on s390x.
1785 2013-07-28 Paulo Andrade <pcpa@gnu.org>
1787 * check/lightning.c: Do not assume casting a double NaN or
1788 Inf to float will produce the expected float NaN or Inf.
1789 This is not true at least under s390x.
1791 2013-07-28 Paulo Andrade <pcpa@gnu.org>
1793 * check/check.arm.sh, check/check.sh, check/check.swf.sh,
1794 check/check.x87.sh: Properly check test programs output,
1795 not just rely on the test program self testing the results
1798 2013-07-28 Paulo Andrade <pcpa@gnu.org>
1800 * lib/jit_aarch64.c: Remove unused macros left from cut&paste
1803 2013-07-16 Paulo Andrade <pcpa@gnu.org>
1805 * include/lightning/jit_aarch64.h, lib/jit_aarch64-cpu.c,
1806 lib/jit_aarch64-fpu.c, lib/jit_aarch64.c: New files
1807 implementing the new aarch64 port, as a new architecture,
1808 not as an expansion of the existing armv[4-7] port.
1810 * check/lightning.c: Add aarch64 support and a small
1811 change to recognize character constants as immediate
1814 * check/float.tst: Add aarch64 preprocessor conditionals
1815 to select proper expected value when converting [+-]Inf
1818 * include/lightning/jit_arm.h, lib/jit_arm.c: Minor changes
1819 to better match the new aarch64 files.
1821 * configure.ac, include/lightning.h,
1822 include/lightning/Makefile.am, include/lightning/jit_private.h,
1823 lib/Makefile.am, lib/lightning.c: Minor adjustments
1824 for the aarch64 port.
1826 2013-07-08 Paulo Andrade <pcpa@gnu.org>
1828 * NEWS, THANKS, configure.ac, doc/version.texi: Update for
1829 the 1.99a second alpha release.
1831 2013-06-25 Paulo Andrade <pcpa@gnu.org>
1833 * lib/jit_mips.c: Correct cut&paste error that caused wrong
1834 stack offset calculation for double arguments in stack in
1836 Correct typo in the __LITTLE_ENDIAN macro name, that came
1837 from cut&paste error in the original typo in lib/jit_ppc.c.
1839 * lib/jit_ia64.c, lib/jit_ppc.c: Correct typo in the
1840 __LITTLE_ENDIAN macro name.
1842 2013-06-22 Paulo Andrade <pcpa@gnu.org>
1844 * check/lightning.c, configure.ac, include/lightning.h,
1845 lib/lightning.c: Add tests and quirks to build/detect
1846 and/or work on Irix.
1848 * include/lightning/jit_mips.h, lib/jit_mips-cpu.c,
1849 lib/jit_mips-fpu.c, lib/jit_mips.c: Adapt code to run
1850 in big endian mips, using the n32 abi.
1852 2013-06-18 Paulo Andrade <pcpa@gnu.org>
1854 * include/lightning.h: Minor extra preprocessor testing
1855 to "detect" byte order on x86 solaris, that now builds
1856 and pass all test cases.
1858 2013-06-18 Paulo Andrade <pcpa@gnu.org>
1860 * lib/jit_sparc-cpu.c: Correct compiler warning of value
1861 used before assignment. The usage is bogus as the api
1862 requires always patching jumps, but the random value used
1863 could cause an assertion due to invalid displacement.
1865 * lib/jit_sparc.c: Always load and store double arguments
1866 in stack as 2 float loads or stores, for safety, as unaligned
1867 access is not allowed in Sparc Solaris.
1869 2013-06-14 Paulo Andrade <pcpa@gnu.org>
1871 * configure.ac: Force -mlp64 to CFLAGS on HP-UX ia64 port.
1872 It is the only supported mode, and expects gcc as C compiler.
1874 * include/lightning.h, lib/jit_ia64-cpu.c, lib/jit_ia64.c:
1875 Correct ia64 port to work on HP-UX that runs it in big endian
1878 2013-06-10 Paulo Andrade <pcpa@gnu.org>
1880 * lib/jit_hppa.c: Sanitize the cache synchronization inline
1881 assembly code that was doing twice the work and redundantly
1882 flushing the end address every loop iteration.
1884 2013-06-09 Paulo Andrade <pcpa@gnu.org>
1886 * configure.ac, check/Makefile.am, doc/Makefile.am: Do not
1887 explicitly link to -ldl, but instead autodetect the library
1888 with dlopen, dlsym, etc.
1890 * check/lightning.c: Add workaround to apparently buggy
1891 getopt in HP-UX that sets optind to the wrong index, and
1892 use RTLD_NEXT on HP-UX instead of RTLD_DEFAULT to dlsym
1895 * include/lightning.h: Rework definitions of wordsize and
1896 byte order to detect proper values on HP-UX.
1898 * lib/lightning.c: Minor correction to use MAP_ANONYMOUS
1899 instead of MAP_ANON on HP-UX.
1901 * lib/jit_hppa.c: Float arguments must be passed on integer
1902 registers on HP-UX, not only for varargs functions.
1903 Add code to properly clear instruction cache. This was
1904 not required on Debian hppa port, but may have been working
1907 * lib/jit_hppa-cpu.c: Follow pattern of HP-UX binaries and
1908 use bve,n instead of bv,n to return from functions.
1910 * lib/jit_hppa-fpu.c: For some reason "fst? frX,rX,(rY)" did
1911 not work on the tested computer (HP-UX B.11.23 U 9000/785 HP-UX)
1912 so the code was changed, at first for __hpux only to add the
1913 base and offset register and use the instruction with an
1914 immediate (zero) offset.
1916 2013-06-07 Paulo Andrade <pcpa@gnu.org>
1918 * check/lightning.c, lib/jit_disasm.c, lib/jit_ppc-cpu.c,
1919 lib/jit_ppc-fpu.c, lib/jit_ppc.c, include/lightning.h,
1920 include/lightning/jit_ppc.h, include/lightning/jit_private.h:
1921 Adapt code to work on 32 bit AIX ppc using gcc. Most changes
1922 are basically to adapt the elf64 logic to 32 bit, as it does
1923 not use the same convention of 32 bit Darwin ppc.
1925 * check/stack.tst: Add a fake memcpy function to the test
1926 case if running under AIX, as it is not available to dlsym.
1928 * configure.ac: Check for getopt.h header, not available in
1931 2013-06-01 Paulo Andrade <pcpa@gnu.org>
1933 * include/lightning/jit_hppa.h, lib/jit_hppa-cpu.c,
1934 lib/jit_hppa-fpu.c, lib/jit_hppa.c: New files implementing
1935 the hppa port. Built on Debian Linux PA-RISC 2.0, 32 bit.
1937 * check/float.tst: Add preprocessor for hppa expected
1938 values when converting NaN and +-Inf to an integer.
1940 * check/ldst.inc: Ensure double load/store tests use an
1941 8 byte aligned address by default.
1943 * lib/lightning.c: Correct a bug found during tests in
1944 the new port, where qmul* and qdiv* were not properly
1945 setting one of the result registers as modified in the
1946 function, what would be a problem if the only "write"
1947 usage were the qmul* or qdiv*.
1949 * check/varargs.tst, check/varargs.ok: Add one extra
1950 interleaved integer/double test to validate proper code
1951 generation in the extra case.
1953 * check/lightning.c, configure.ac, include/lightning.h,
1954 include/lightning/Makefile.am,
1955 include/lightning/jit_private.h, lib/Makefile.am,
1956 lib/jit_disasm.c: Update for the hppa port.
1958 2013-04-27 Paulo Andrade <pcpa@gnu.org>
1960 * check/varargs.tst: Correct misplaced .align directive
1961 that was causing the double buffer to not be aligned at
1963 * lib/jit_ia64-cpu.c:
1964 Properly implement abi for excess arguments passed on
1966 Simplify load/store with immediate displacement argument
1968 Simplify some calls to "subi" changing to "addi" with
1969 a negative argument.
1970 Remove some #if 0'ed code, that could be useful in
1971 special conditions, but the most useful one would be
1972 to "optimize" "static" jit functions, but for the sake
1973 of simplicity, jit functions are implemented in a way
1974 that can be passed back to C code as C function pointers.
1975 Add an attribute to prototypes of several unused functions.
1976 These functions are defined for the sake of implementing all
1977 Itanium documented instructions, but a significant amount of
1978 them is not used by lightning.
1979 * lib/jit_ia64-fpu.c: Simplify load/store with zero immediate
1980 displacement and add unused attribute for functions not used
1981 by lightning, but required to provide macros implementing all
1982 Itanium documented instructions.
1983 * lib/jit_ia64.c: Update for the properly implemented abi
1984 for stack arguments.
1985 * lib/lightning.c: Mark an unused function as such.
1987 2013-04-27 Paulo Andrade <pcpa@gnu.org>
1990 Correct immediate range check of integer comparisons when
1991 inverting arguments.
1992 Correct gei_u that was not decrementing immediate when
1993 inverting arguments.
1994 Correct b?add* and b?sub* that were not properly updating
1995 the result register.
1997 2013-04-27 Paulo Andrade <pcpa@gnu.org>
1999 * lib/jit_ia64-cpu.c: Correct wrong mapping of 2 instructions
2000 in "M-, stop, M-, stop" translation, that was ignoring the
2001 last stop (implemented as a nop I- stop).
2003 * lib/jit_ia64-fpu.c: Properly implement fnorm.s and fnorm.d,
2004 as well as the proper integer to float or double conversion.
2006 2013-04-27 Paulo Andrade <pcpa@gnu.org>
2008 * lib/jit_ia64-cpu.c: Correct bogus implementation of ldr_T
2009 for signed integers, that was using ld1.s, ld2.s and ld4.s.
2010 The ".s" stands for speculative load, not sign extend.
2012 * lib/jit_ia64-fpu.c: Correct bogus implementation of ldxr_T
2013 for float and double. The third (actually, second) argument
2014 is indeed added to the base register, but the base register
2015 is modified. The actual M7 implementation was already correct,
2016 just the ldxr_f and ldxr_d implementation that was kept in
2017 a prototype state, misinterpreting what M7 does.
2019 2013-04-27 Paulo Andrade <pcpa@gnu.org>
2021 * lib/jit_ia64-cpu.c: Correct X2 pattern matching by preventing
2022 it to attempt to require a stop between the L and the X
2023 instruction; that is, check the registers and predicates
2024 before emitting the L instruction, not after.
2026 * lib/jit_ia64-fpu.c: Slightly simplify and correct
2027 divr_f and divrd_d implementation.
2029 * check/lightning.c: Add __ia64__ preprocessor define
2032 * check/alu.inc, check/clobber.tst, check/float.tst: Define
2033 several macros conditionally to __ia64__. This is required
2034 because __ia64__ jit generation can use way too many memory,
2035 due to not implementing instruction reordering to avoid
2036 as much as possible "stops", what causes way too many nops
2037 to be generated, as well as the fact that division and
2038 remainder requires function calls, and float division
2039 requires significant code to implement.
2041 2013-04-27 Paulo Andrade <pcpa@gnu.org>
2043 * include/lightning.h: Add new backend specific movr_w_d,
2044 movr_d_w and movi_d_w codes as helpers to ia64 varargs
2045 functions arguments.
2047 * lib/jit_ia64-cpu.c:
2048 Correct wrong encoding of A5 small integers.
2049 Correct define of "mux" instruction modifiers.
2050 Correct ordering of arguments and predicates of cmp_xy
2051 implementation with immediate arguments; like most other
2052 codes with an immediate, the immediate is the second, not
2055 * lib/jit_ia64-fpu.c: Actual implementation of the code
2056 to move to/from gpr to/from fpr, to implement varargs abi.
2058 * lib/jit_ia64.c: Make fpr argument registers not allocatable
2059 as temporaries, no need for the extra checks when there are
2062 * lib/jit_print.c, lib/lightning.c: Minor updates for the
2063 new movr_w_d, movr_d_w and movi_d_w codes.
2065 2013-04-26 Paulo Andrade <pcpa@gnu.org>
2067 * lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c: Correct code to
2068 also insert a stop to break an instruction group if a
2069 register is written more than once in the same group.
2070 This may happen if a register is argument and result of
2071 some lightning call (not a real instruction). The most
2072 common case should be code in the pattern:
2076 where "rn" would end up holding "largenum".
2077 But the problem possibly could happen in other circumstances.
2079 2013-04-26 Paulo Andrade <pcpa@gnu.org>
2081 * include/lightning/jit_ia64.h, lib/jit_ia64-cpu.c,
2082 lib/jit_ia64-fpu.c, lib/jit_ia64.c:
2083 Relocate JIT_Rn registers to the local registers, as, like
2084 float registers, div/rem and sqrt are implemented as function
2085 calls, and may overwrite non saved scratch registers.
2086 Change patch_at to receive a jit_code_t instead of a
2087 jit_node_t, so that it is easier to "inline" patches when
2088 some instruction requires complex code to implement, e.g.
2090 Correct arguments to FMA and FMA like instructions that,
2091 due to a cut&paste error were passing the wrong argument
2092 to the related F- implementation function.
2093 Rewrite ltgt to return the proper result if one (or both)
2094 of the arguments is unordered.
2096 2013-04-26 Paulo Andrade <pcpa@gnu.org>
2098 * include/lightning/jit_ia64.h, include/lightning/jit_private.h,
2099 lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c, lib/jit_ia64.c,
2100 lib/lightning.c: Rework code to detect need of a "stop" to
2101 also handle predicates, as if a predicate is written, it
2102 cannot be read in the same instruction group.
2103 Use a single jit_regset_t variable for all registers when
2104 checking need for a stop (increment value by 128 for
2106 Correct wrong "subi" implementation, as the code executed
2107 is r0=im-r1, not r0=r1-im.
2108 Use standard lightning 6 fpr registers, and rework to
2109 use callee save float registers, that may be spill/reloaded
2110 in prolog/epilog. This is required because some jit
2111 instructions implementations need to call functions; currently
2112 integer div/mod and float sqrt, what may change the value of
2113 scratch float registers.
2114 Rework point of "sync" of branches that need to return a
2115 patch'able address, because the need for a "stop" before a
2116 predicate read causes all branches to be the instruction
2117 in slot 0, as there is no template to "stop" and branch
2118 in the same instruction "bundle".
2120 2013-04-25 Paulo Andrade <pcpa@gnu.org>
2122 * include/lightning/jit_ia64.h, lib/jit_ia64-cpu.c,
2123 lib/jit_ia64-fpu.c, lib/jit_ia64.c: New files implementing
2124 the basic infrastructure of an Itanium port. The code
2125 compiles and can generate jit for basic hello world like
2128 * check/lightning.c, configure.ac, include/lightning.h,
2129 include/lightning/Makefile.am, include/lightning/jit_private.h,
2130 lib/Makefile.am, lib/lightning.c: Update for the Itanium
2133 * lib/jit_mips-cpu.c, lib/jit_mips.c: Correct typo and
2134 make the jit_carry register local to the jit_state_t.
2135 This matches code reviewed in the Itanium port, that
2136 should use the same base logic to handle carry/borrow.
2138 2013-04-10 Paulo Andrade <pcpa@gnu.org>
2140 * include/lightning/jit_private.h, lib/jit_arm.c,
2141 lib/jit_mips-cpu.c, lib/jit_mips.c, lib/jit_ppc-cpu.c,
2142 lib/jit_ppc.c, lib/jit_print.c, lib/jit_sparc-cpu.c,
2143 lib/jit_sparc.c, lib/jit_x86-cpu.c, lib/jit_x86.c,
2144 lib/lightning.c: Change all jit_regset macros to take
2145 a pointer argument, to avoid structure copies when
2146 adding a port to an architecture with more than 64
2149 2013-04-08 Paulo Andrade <pcpa@gnu.org>
2151 * lib/jit_arm.c, lib/jit_ppc.c: Do not rely on __clear_cache
2152 aligning to the next page boundary the end argument. It may
2153 actually truncate it.
2155 2013-03-29 Paulo Andrade <pcpa@gnu.org>
2157 * include/lightning/jit_private.h, lib/jit_arm.c, lib/jit_memory.c,
2158 lib/jit_mips.c, lib/jit_ppc.c, lib/jit_sparc.c, lib/jit_x86.c,
2159 lib/lightning.c: Do not start over jit generation if can grow
2160 the code buffer with mremap without moving the base pointer.
2162 2013-03-29 Paulo Andrade <pcpa@gnu.org>
2164 * lib/jit_memory.c: Implement a simple memory allocation wrapper
2165 to allow overriding calls to malloc/calloc/realloc/free, as well
2166 as ensuring all memory containing pointers is zero or points to
2169 * include/lightning.h, include/lightning/jit_private.h: Definitions
2170 for the memory allocation wrapper.
2172 * lib/Makefile.am: Update for new jit_memory.c file.
2174 * lib/jit_arm.c, lib/jit_disasm.c, lib/jit_mips.c, lib/jit_note.c,
2175 lib/jit_ppc.c, lib/jit_sparc.c, lib/jit_x86.c, lib/lightning.c:
2176 Use the new memory allocation wrapper code.
2178 2013-03-22 Paulo Andrade <pcpa@gnu.org>
2180 * configure.ac, include/lightning/jit_private.h, lib/lightning.c:
2181 Remove dependency on gmp. Only a simple bitmap was required, and
2182 that was not enough reason to force linking to gmp and possible
2183 complications caused by it.
2185 2013-03-10 Paulo Andrade <pcpa@gnu.org>
2187 * include/lightning.h: Add check for __powerpc__ defined
2188 in Linux, while Darwin defines __ppc__.
2190 * include/lightning/jit_ppc.h: Adjust register definitions
2191 for Darwin 32 bit and Linux 64 bit ppc usage and/or ABI.
2193 * include/lightning/jit_private.h: Add proper check for
2194 Linux __powerpc__ and an data definition for an workaround
2195 to properly handle code that starts with a jump to a "main"
2198 * lib/jit_disasm.c: Add extra disassembler initialization
2201 * lib/jit_ppc-cpu.c: Add extra macros and functions, and
2202 correct/adapt previous ones to handle powerpc64.
2204 * lib/jit_ppc-fpu.c: Adapt for 64 bit wordsize. Basically
2205 add conversion from/to int32/int64 and proper handling of
2206 load/store offsets too large for 32 bit.
2208 * lib/jit_ppc.c: Add calls to 64 bit codes and adaptation
2209 for the PowerPC 64 bit Linux ABI.
2211 * lib/jit_arm.c, lib/jit_mips.c, lib/jit_sparc, lib/jit_x86.c,
2212 lib/lightning.c: Correct off by one error when restarting jit
2213 of a function due to finding too late that needs to spill/reload
2214 some register. Problem was found by accident on a very special
2215 condition during PowerPC 64 code adaptation.
2217 2013-03-08 Paulo Andrade <pcpa@gnu.org>
2219 * check/lightning.c: Add missing ppc preprocessor definition.
2221 2013-03-06 Paulo Andrade <pcpa@gnu.org>
2223 * check/float.tst: Comment out the int to negative infinity
2224 test in mips for the moment because not all Loongson agrees
2227 * lib/jit_disasm.c: Add a test instead of an assertion
2228 when loading symbols for disassembly due to a failure with
2229 a simple binutils build in Debian mipsel64.
2231 2013-03-06 Paulo Andrade <pcpa@gnu.org>
2233 * include/lightning/jit_private.h, lib/jit_arm-cpu.c,
2234 lib/jit_arm.c, lib/jit_disasm.c, lib/jit_mips-cpu.c,
2235 lib/jit_mips.c, lib/jit_note.c, lib/jit_ppc-cpu.c,
2236 lib/jit_ppc.c, lib/jit_print.c, lib/jit_sparc-cpu.c,
2237 lib/jit_sparc.c, lib/jit_x86-cpu.c, lib/jit_x86.c,
2238 lib/lightning.c: Add an extra structure for data storage
2239 during jit generation, and release it after generating
2240 jit, to reduce a bit memory usage, and also to make it
2241 easier to understand what data is available during
2244 2013-03-06 Paulo Andrade <pcpa@gnu.org>
2246 * lib/lightning.c: Make data and code buffer readonly.
2248 2013-02-20 Paulo Andrade <pcpa@gnu.org>
2250 * doc/body.texi: Fool proof validate the examples of what
2251 an assembly-language programmer would write and correct the
2252 wrong sparc example.
2254 2013-02-19 Paulo Andrade <pcpa@gnu.org>
2256 * doc/body.texi: Add back the SPARC code generation example.
2258 2013-02-19 Paulo Andrade <pcpa@gnu.org>
2260 * check/lightning.c: Remove state flag to work with partial
2261 sparc port, by just disassembling if there was incomplete
2264 * jit_sparc-cpu.c: Correct wrong range check for immediate
2265 integer constants (off by one bit shift).
2266 Correct macro implementing equivalent "rd %y, rd" assembly.
2267 Implement qmul* and qdiv*.
2269 * jit_sparc.c: Update for qmul* and qdiv* and remove logic
2270 to handle incomplete code generation during sparc port.
2272 2013-02-18 Paulo Andrade <pcpa@gnu.org>
2274 * check/float.tst: Add sparc to list of known NaN and +-Inf
2275 to integer conversion.
2277 * check/lightning.c: Define __sparc__ to preprocessor in
2280 * include/lightning/jit_private.h: Correct wrong definition
2281 of emit_stxi_d, that has lived for a long time, but would
2282 cause problems whenever needing to spill/reload a float
2285 * include/lightning/jit_sparc.h: Can only use %g2,%g3,%g4
2286 for scratch variables, as other "global" registers are
2287 reserved for the system, e.g. libc.
2288 Reorder float register naming to make it easier to
2289 access odd float registers, so that generating code for
2290 pusharg and getarg is easier for the IR.
2292 * lib/jit_mips-cpu.c, lib/jit_ppc-cpu.c: Update to match
2293 new code in jit_sparc-cpu.c. It must call jit_get_reg
2294 with jit_class_nospill if using the register to move
2295 an unconditional branch address to it, as the reload
2296 will not happen (actually could happen in the delay
2299 * lib/jit_sparc-cpu.c: Correct wrong macro definition for
2301 Properly implement div* and implement rem. Div* needs
2302 to use the y register, and rem* needs to be synthesized.
2303 Correct b?sub* macro definitions.
2305 * lib/jit_sparc-fpu.c: Correct reversed float to/from double
2307 Correct wrong jit_get_reg call asking for a gpr and then
2308 using the fpr with that number.
2309 Correct wrong branch displacement computation for
2310 conditional branches.
2312 * lib/jit_sparc.c: Correct getarg_d and pushargi_d implementation.
2313 Add rem* entries to the switch converting IR to machine code.
2315 * lib/lightning.c: Correct a problem detected when adding
2316 the jit_class_nospill flag to jit_get_reg, that was caused
2317 when having a branch to an "epilog" node, what would cause
2318 the code to think all registers in unknown state were live,
2319 while in truth, all registers in unknown state in the
2320 "just after return" point are actually dead.
2322 2013-02-17 Paulo Andrade <pcpa@gnu.org>
2324 * include/lightning/jit_sparc.h, lib/jit_sparc-cpu.c,
2325 lib/jit_sparc-fpu.c, lib/jit_sparc.c: New files implementing
2326 the basic framework of the sparc port.
2328 * configure.ac, include/lightning.h, include/lightning/Makefile.am,
2329 include/lightning/jit_private.h, lib/jit_disasm.c: Update
2330 for the sparc port framework.
2332 * lib/jit_mips.c: Correct reversed retr/reti logic.
2334 * lib/jit_ppc.c: Correct misspelled __LITTLE_ENDIAN.
2336 * lib/lightning.c: Always do byte hashing in hash_data, because
2337 the logic to "compress" strings causes large pointers to not
2338 be guaranteed aligned at 4 byte boundaries.
2339 Update for the sparc port framework.
2341 2013-02-11 Paulo Andrade <pcpa@gnu.org>
2343 * lib/jit_arm.c: Correct jit_pushargi_f in the arm hardfp abi.
2344 Most of the logic uses even numbered register numbers, so that
2345 a float and a double can be used in the same register, but
2346 the abi requires packing the float arguments, so jit_pushargi_f
2347 needs to allocate a temporary register to modify only the
2348 proper register argument (or be very smart to push two
2349 immediate arguments if applicable).
2351 2013-02-11 Paulo Andrade <pcpa@gnu.org>
2353 * include/lightning.h, lib/lightning.c: Implement the new
2354 jit_clear_state and jit_destroy_state calls. jit_clear_state
2355 releases all memory not required during jit_execution; that
2356 is, leaves only the mmap'ed data and code buffers allocated.
2357 jit_destroy_state releases the mmap'ed buffers as well as
2358 the jit_state_t object itself, that holds pointers to the
2359 code and data buffers, as well as annotation pointers (for
2360 disassembly or backtrace) in the data buffer.
2362 * lib/jit_note.c: Correct invalid vector offset access.
2364 * check/ccall.c, check/lightning.c, doc/ifib.c, doc/incr.c,
2365 doc/printf.c, doc/rfib.c, doc/rpn.c: Use the new jit_clear_state
2366 and jit_destroy_state calls, to demonstrate the new code to
2367 release all jit memory.
2369 * doc/body.texi: Add basic documentation and usage description
2370 of jit_clear_state and jit_destroy_state.
2372 2013-02-11 Paulo Andrade <pcpa@gnu.org>
2374 * include/lightning/jit_private.h, lib/jit_note.c, lib/lightning.c:
2375 Store all annotation information in the mmap'ed area reserved for
2376 read only data. This adds code to not allocate memory for jit_note_t
2377 objects, and to relocate jit_line_t objects and its contents after
2378 calculating annotation information. The jit_line_t objects are
2379 relocated because it is not possible to always calculate before
2380 hand data layout because note information may be extended or
2381 redundant entries removed, as well as allowed to be added in
2382 non sequential order.
2383 A bug was also corrected in _jit_set_note, that was causing it
2384 to allocate new jit_line_t objects when not needed. It was still
2385 working correctly, but allocating way more memory than required.
2387 2013-02-05 Paulo Andrade <pcpa@gnu.org>
2389 *include/lightning.h, lib/lightning.c: Add the new jit_live code
2390 to explicitly mark a register as live. It is required to avoid
2391 assuming functions always return a value in the gpr and fpr return
2392 register, and to avoid the need of some very specialized codes
2393 that vary too much from backend to backend, to instruct the
2394 optimization code the return register is live.
2396 * lib/jit_arm.c, lib/jit_mips.c, lib/jit_ppc.c, lib/jit_print.c,
2397 lib/jit_x86.c: Update for the new jit_live code.
2399 * check/ret.ok, check/ret.tst: New files implementing a simple
2400 test case that would previously fail at least in ix86/x86_64.
2402 * check/Makefile.am: Update for new "ret" test case.
2404 2013-02-05 Paulo Andrade <pcpa@gnu.org>
2406 * lib/jit_ppc-cpu.c, lib/jit_ppc.c: Validate and correct
2407 problems in the qmul and qdiv ppc implementation.
2409 2013-02-04 Paulo Andrade <pcpa@gnu.org>
2411 * include/lightning.h, include/lightning/jit_private.h,
2412 lib/jit_arm-cpu.c, lib/jit_arm.c, lib/jit_mips-cpu.c,
2413 lib/jit_mips.c, lib/jit_ppc-cpu.c, lib/jit_ppc.c,
2414 lib/jit_x86-cpu.c, lib/jit_x86.c, lib/lightning.c:
2415 Implement the new qmul and qdiv instructions that return signed
2416 and unsigned lo/hi multiplication result and div/rem division result.
2417 These should be useful for jit translation of code that needs to
2418 know if a multiplication overflows (no branch opcode added) or if
2419 a division is exact (easy check if remainder is zero).
2421 * check/lightning.c, lib/jit_print.c, check/Makefile.am,
2422 check/all.tst: Update for the new qmul and qdiv instructions.
2424 * check/qalu.inc, check/qalu_div.ok, check/qalu_div.tst,
2425 check/qalu_mul.ok, check/qalu_mul.tst: New files implementing
2426 simple test cases for qmul and qdiv.
2428 2013-01-30 Paulo Andrade <pcpa@gnu.org>
2430 * doc/body.texi: Correct "jmpi" description that incorrectly
2431 told it was possible to pass any address as jump target. The
2432 only way to do that is "movi+jmpr".
2434 2013-01-30 Paulo Andrade <pcpa@gnu.org>
2436 * lib/jit_x86-cpu.c: Correct undefined behavior code.
2437 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56143
2439 2013-01-29 Paulo Andrade <pcpa@gnu.org>
2441 * configure.ac: Use AC_CONFIG_HEADERS instead of AC_CONFIG_HEADER
2442 to have HAVE_CONFIG_H defined with latest aclocal.
2444 * include/lightning/jit_private.h, lib/lightning.c: Add new
2445 abstraction to use an heuristic to calculate amount of space
2446 required for jit generation, and code to reallocate buffer if
2447 did miscalculate it.
2449 * lib/jit_arm.c, lib/jit_mips.c, lib/jit_ppc.c, lib/jit_x86.c:
2450 Update to use new code to estimate and resize of required buffer
2453 * lib/jit_x86-cpu.c: Minor cosmetic change to avoid adding a
2454 non required rex prefix when calling a function pointer stored
2457 2013-01-24 Paulo Andrade <pcpa@gnu.org>
2459 * check/Makefile.am: "make debug" target should pass only
2460 the main test tool program as argument for running gdb
2462 * configure.ac: Add the --enable-assertions options.
2464 * doc/Makefile.am, doc/body.texi, doc/lightning.texi:
2465 Major rewrite of the documentation to match the current
2468 * doc/version.texi: Automatic date update.
2470 * doc/ifib.c, doc/incr.c, doc/printf.c, doc/rfib.c, doc/rpn.c:
2471 Implementation of the documentation examples, that are also
2472 compiled during a normal build.
2474 * doc/p-lightning.texi, doc/porting.texi, doc/toc.texi,
2475 doc/u-lightning.texi, doc/using.texi: These files were
2476 renamed in the documentation rewrite, as the documentation
2477 was significantly trimmed due to full removal of the porting
2478 chapters. Better porting documentation should be added but
2479 for the moment it was just removed the documentation not
2480 matching the implementation.
2482 2013-01-18 Paulo Andrade <pcpa@gnu.org>
2484 * lib/jit_note.c: Correct bounds check and wrong code keeping
2485 a pointer that could be changed after a realloc call.
2487 2013-01-18 Paulo Andrade <pcpa@gnu.org>
2489 * check/3to2.tst, check/add.tst, check/allocai.tst, check/bp.tst,

2497 lib/jit_x86.c, lib/lightning.c: Extend the "jit_note" abstraction
2498 with the new "jit_name" call, that receives a string argument, and
2499 should usually be called to mark boundaries of functions of code
2500 generating jit (that is, it is not expected that the language
2501 generating jit map its functions to jit functions).
2503 2013-01-17 Paulo Andrade <pcpa@gnu.org>
2505 * check/add.tst, check/allocai.tst, check/bp.tst, check/divi.tst,
2506 check/fib.tst, check/lightning.c, include/lightning/jit_arm.h,
2507 include/lightning/jit_mips.h, include/lightning/jit_ppc.h,
2508 include/lightning/jit_private.h, include/lightning/jit_x86.h:
2509 Make JIT_RET, JIT_FRET and JIT_SP private. These should not be
2510 used in any operations due to frequently having special
2511 constraints (usually JIT_FRET). JIT_FP must be made available
2512 because it must be used as the base register to access stack
2513 space allocated with jit_allocai.
2515 2013-01-14 Paulo Andrade <pcpa@gnu.org>
2517 * include/lightning.h, lib/lightning.c: Add an extra align
2518 argument to the jit_data call (that should be made private),
2519 so that it should not align strings at 8 bytes.
2520 Correct the jit_note call to include the null ending byte
2521 when adding label/note names to the "jit data section".
2523 2013-01-11 Paulo Andrade <pcpa@gnu.org>
2525 * lib/jit_note.c: New file implementing a simple string+integer
2526 annotation, that should be used to map filename and line number
2527 to offsets in the generated jit.
2529 * include/lightning.h, lib/lightning.c: Update for the new
2531 Add an extra mandatory argument to init_jit, that is used
2532 as argument to bfd_openr.
2533 Change from generic void* to char* the argument to jit_note
2534 and add an extra integer argument, to map to filename and
2537 * check/ccall.c, check/lightning.c, include/lightning/jit_private.h,
2538 lib/jit_arm.c, lib/jit_disasm.c, lib/jit_mips.c, lib/jit_ppc.c,
2539 lib/jit_print.c, lib/jit_x86.c: lib/Makefile.am: Update for the
2540 new annotation code.
2542 * configure.ac, check/Makefile.am: Update to work with latest
2545 2013-01-09 Paulo Andrade <pcpa@gnu.org>
2547 * include/lightning.h, lib/jit_arm.c, jit_mips-fpu.c,
2548 lib/jit_mips.c, lib/jit_print.c, lib/jit_x86.c, lib/lightning.c:
2549 Remove the jit_code_getarg_{f,d} and jit_code_pusharg{i,r}_{f,d}
2550 calls, replacing them with the new, internal only, jit_movr_w_f,
2551 jit_mov{r,i}_f_w, jit_movr_ww_d, and jit_mov{i,r}_d_ww, that
2552 better describe the operation being done, and allow removing
2553 the hackish code to detect special conditions for arm when
2554 moving from/to vfp from/to a grp register pair.
2555 Rename jit_code_retval_{f,d} to jit_code_x86_retval_{f,d} as
2556 it is specific to 32 bit x86, and used to move abi return
2557 value in x87 register to a sse register.
2559 2013-01-05 Paulo Andrade <pcpa@gnu.org>
2561 * check/cccall.c, check/ccall.ok: New test case to validate
2562 interleaved calls from/to C code and jit.
2564 * check/Makefile.am: Update for the new ccall test case.
2566 * include/lightning.h, lib/lightning.c: Add the new jit_address
2567 call that returns the real/final address of a "note" in the
2568 generated jit. It requires a jit_node_t as returned by the
2569 jit_note call, and is only valid after calling jit_emit.
2570 Add an intermediate solution to properly handle arm
2571 soft and softfp modes that move a double to an integer register
2572 pair. Currently it just adds extra tests for the condition,
2573 but the proper solution should be to have extra lightning
2574 codes for these conditions, codes which should be only used
2575 by the backends that need it, and merged with the existing
2578 * include/lightning/jit_private.h: Add new jit_state_t flag
2579 to know it finished jit_emit, so that calls to jit_address
2582 * lib/jit_mips.c: Correct abi implementation so that the
2583 new ccall test case pass. Major problem was using
2584 _jit->function.self.arg{i,f} as boolean values, but that
2585 would cause lightning.c:patch_registers() to incorrectly
2586 assume only one register was used as argument when calling
2587 jit_regarg_p(); _jit->function.self.arg{i,f} must be the
2588 number of registers used as arguments (in all backends).
2590 * lib/jit_x86.c: Add workaround, by marking %rax as used,
2591 to a special condition, when running out of registers and the
2592 allocator trying to spill and reload %rax, but %rax was used
2593 as a pointer to a function, what would cause the reload to
2594 destroy the return value. This condition can be better
2595 generalized, but the current solution is good enough.
2597 * include/lightning/jit_ppc.h, lib/jit_ppc-cpu.c, lib/jit_ppc.c:
2598 Rewrite logic to handle arguments, as the original code was
2599 written based on a SysV pdf about the generic powerpc ABI,
2600 what did "invent" a new abi for the previous test cases, but
2601 failed in the new ccall test in Darwin PPC. Now it properly
2602 handles 13 float registers for arguments, as well as proper
2603 computation of stack offsets when running out of registers
2606 2013-01-02 Paulo Andrade <pcpa@gnu.org>
2608 * check/float.tst: Correct test case to match ppc also
2609 converting positive infinity to 0x7fffffff.
2611 * lib/jit_arm-swf.c: Correct typos with double underscores.
2613 * lib/lightning.c: Correct remaining wrong reverse jump logic.
2615 2012-12-29 Paulo Andrade <pcpa@gnu.org>
2617 * lib/lightning.c: Correct both, wrong and confusing logic
2618 to compute the reverse of a jump. Now it properly matches
2619 C semantics for "eq" (==) and "ne" (!=) and correct computation
2620 of reverse of "uneq" as "gt".
2622 * check/branch.tst: Update "ne" float branch check that
2623 previously happened to be wrongly tested with a NaN argument.
2625 2012-12-29 Paulo Andrade <pcpa@gnu.org>
2627 * check/float.ok, check/float.tst: New test cases implementing
2628 extensive validation of float comparison and branch code
2629 generation as well as integer conversion, involving NaN and
2632 * lib/jit_arm-swf.c, lib/jit_x86-sse.c, lib/jit_x86-x87.c:
2633 Correct bugs found by new float test case.
2635 * lib/jit_x86.c: Correct cut&paste error added in commit to
2636 convert jit_arg* return value to a jit_node_t*, that would
2637 cause it to not properly handle double arguments in ix86.
2639 * check/Makefile.am: Update for the new test case.
2641 2012-12-28 Paulo Andrade <pcpa@gnu.org>
2643 * check/lightning.c, include/lightning.h, lib/jit_arm.c,
2644 lib/jit_mips.c, lib/jit_ppc.c, lib/jit_print.c, lib/jit_x86.c,
2645 lib/lightning.c: Change return value of jit_arg{,_f,_d} to
2646 a jit_node_t* object, that should be used as argument to
2647 jit_getarg_{c,uc,s,us,i,ui,l,f,d}. This just requires changing
2648 from jit_int32_t to jit_pointer_t (or jit_node_t*) the "handle"
2649 for the getarg calls, with the benefit that it makes it easy
2650 to implement patching of the stack address of non register
2651 arguments, this way allowing to implement variable size stack
2652 frames if applicable; useful if there are too many registers and
2653 jit functions uses only a few callee save registers.
2655 2012-12-27 Paulo Andrade <pcpa@gnu.org>
2657 * lib/jit_arm.c, lib/jit_mips-cpu.c, lib/jit_mips.c: Correct
2658 regressions when patching jit_calli for a forward function.
2660 * lib/jit_ppc-cpu.c: Correct wrong arguments to ANDI opcode
2661 in jit_getarg_u{c,s} implementation.
2663 2012-12-23 Paulo Andrade <pcpa@gnu.org>
2665 * check/call.ok, check/call.tst: New test cases to validate
2666 simple typed argument and return values in function calls.
2668 * check/lightning.c: Properly handle jit_movi of labels for
2669 backward and forward code labels.
2671 * check/Makefile.am: Update for new test case.
2673 2012-12-23 Paulo Andrade <pcpa@gnu.org>
2675 * check/carry.ok, check/carry.tst: New test case to validate
2676 carry condition handling.
2678 * check/Makefile.am: Update for new test case.
2680 2012-12-22 Paulo Andrade <pcpa@gnu.org>
2682 * lib/jit_ppc-cpu.c, lib/jit_ppc.c: Implement logic for
2683 jit_htonr for big endian, so that ppc (big endian) pass the
2684 new clobber.tst test case.
2686 2012-12-22 Paulo Andrade <pcpa@gnu.org>
2688 * lib/jit_arm.c: Correct use of wrong argument offset
2689 variable in armv7l or float/double argument for varargs
2690 function in armv7hl.
2691 Correct jit_getarg* logic in software float mode to
2692 match expected behavior in other backends, that is, if
2693 a function is not called, it is safe to use a few lightning
2694 calls before a next jit_getarg* call, as done in the test
2695 case check/stack.tst. The proper solution should be to
2696 extend the parser in lib/lightning.c to check if there is
2697 some float operation that will call some (libgcc?) function,
2698 but software float arm should be a very uncommon backend for
2699 lightning, so, just load the already in place arguments
2700 saved to stack, assuming the register argument was clobbered
2701 (what should not be the case most times...).
2703 2012-12-22 Paulo Andrade <pcpa@gnu.org>
2705 * check/clobber.ok, check/clobber.tst: New test case doing
2706 extensive validation tests to ensure registers not used in
2707 a operation are not clobbered.
2709 * check/Makefile.am: Update for new test case.
2711 2012-12-21 Paulo Andrade <pcpa@gnu.org>
2713 * lib/lightning.c: Partially rewrite/revert code to compute
2714 initial register live state at the start of a basic block.
2715 The original logic was corrupted when adding optimizations
2716 to do as few computations as possible in jit_update. The
2717 reglive field must be always a known set of live registers
2718 at the start of a basic block. The value that was incorrect
2719 was the regmask field, that must be the set of registers
2720 that are in unknown state, because they are not known live,
2721 neither set (or possibly not set) in the basic block, and
2722 *must* store the state at the start of the basic block.
2724 2012-12-20 Paulo Andrade <pcpa@gnu.org>
2726 * include/lightning/jit_ppc.h: Correct mismatch of JIT_F{1,5}
2727 with enum codes, that were correct, and returned by jit_f().
2729 * lib/jit_ppc-cpu.c, lib/jit_ppc-fpu.c, lib/jit_ppc.c: Properly
2730 implement and better describe values when generating stack
2733 2012-12-18 Paulo Andrade <pcpa@gnu.org>
2735 * check/stack.ok, check/stack.tst: New files to test data
2736 integrity on a deep chain of stack frames.
2738 * lib/jit_arm.c, lib/jit_arm-cpu.c, lib/jit_mips.c,
2739 lib/jit_mips-cpu.c, lib/jit_ppc.c, lib/jit_ppc-cpu.c,
2740 lib/jit_x86.c, lib/jit_x86-cpu.c: Calculate _jit->function->stack
2741 in the emit stage, otherwise it will calculate it wrong if
2742 need to jit_allocai space to spill registers.
2744 * lib/lightning.c: Correct wrong offset when updating the
2745 "current" jit function pointer in the code that may need to
2746 allocate stack space to spill registers.
2748 * check/lightning.c: Correct off by one data space check.
2750 * check/Makefile.am: Update for new test case.
2752 2012-12-17 Paulo Andrade <pcpa@gnu.org>
2754 * check/fop_abs.ok, check/fop_abs.tst, check/fop_sqrt.ok,
2755 check/fop_sqrt.tst: New files implementing simple test cases
2756 for the extra float operations.
2758 * check/Makefile.am: Update for new test cases.
2760 * check/alu.inc: Add an extra macro to check for unordered
2761 equality on tests where it is expected to use NaN as an
2764 * check/lightning.c: Minor change for proper/common argument
2765 syntax handling ommiting arguments to options.
2767 2012-12-17 Paulo Andrade <pcpa@gnu.org>
2769 * check/Makefile.am: Automatically generate pattern list
2770 of tests with alternate jit generation options. This should
2771 prevent typos and needing to change multiple places after
2774 2012-12-14 Paulo Andrade <pcpa@gnu.org>
2776 * check/lightning.c: Remove the ".cpu name value" syntax,
2777 as it was not able to do proper changes before the jit
2778 internal data structure was initialized. Now it supports
2779 several getopt options to force using different jit
2780 generation options, effectively replacing the previous
2783 * check/run-test: Add simple extra logic to handle differently
2784 named test scripts, used to test things like x87 coprocessor
2785 in ix86, and arm instruction set or software float in armv7l.
2787 * configure.ac: Add some AC_RUN_IFELSE calls to figure at
2788 compile time if can test different code generation options,
2789 and update Makefile generation accordingly.
2791 * check/Makefile.am, lib/jit_arm.c, lib/jit_x86.c: Update to
2792 properly work with the test tool updating the jit_cpu global
2795 * check/check.arm.sh, check/check.swf.sh, check/check.x87.sh:
2796 New wrapper files passing -mthumb=0, mvfp=0 and -mx87=1 to
2797 the test tool, if applicable, so that it can validate alternate
2798 code generation options on test hosts that support them.
2800 2012-12-14 Paulo Andrade <pcpa@gnu.org>
2802 * lib/jit_x86-x87.c, lib/jit_x86.c: Correct test cases in ix86
2803 when using the x87 coprocessor instead of sse2+.
2805 2012-12-14 Paulo Andrade <pcpa@gnu.org>
2807 * include/lightning.h, include/lightning/jit_private.h,
2808 lib/jit_arm.c, lib/jit_mips.c, lib/jit_ppc.c, lib/jit_x86.c,
2809 lib/lightning.c: Make jit_ellipsis implementation not
2810 backend specific. It is not intended to handle va_list
2811 like objects at runtime, as jit_arg* and jit_getarg*
2812 return constant values resolved at parse time, so, effectively
2813 it is not possible to create printf like jit functions, as
2814 there is no va_start, va_arg, va_end, etc, abstraction. This
2815 limitation should be kept for the sake of making new ports
2818 2012-12-14 Paulo Andrade <pcpa@gnu.org>
2820 * include/lightning.h, lib/lightning.c: Add two extra wrapper
2821 functions to avoid need for excess pointer to/from word casts.
2823 * check/lightning.c: Only need for pointer to/from word cast
2824 now is jit_movi, update accordingly.
2826 2012-12-13 Paulo Andrade <pcpa@gnu.org>
2828 * check/varargs.ok, check/varargs.tst: New test cases implementing
2829 simple varargs calls with a large amount of arguments to exercise
2830 excess arguments on stack.
2832 * include/lightning.h: Include config.h if HAVE_CONFIG_H is
2835 * lib/jit_arm.c: Allocate a fpr register, not a gpr one for
2836 temporary when pushing varargs arguments in the stack.
2838 * lib/jit_arm-swf.c: Correct code changing the wrong offset
2839 in jit_absr_d and jit_negr_d in software float.
2841 * lib/jit_mips.c: Correct calculation of offsets of arguments
2844 * lib/jit_ppc.c: Correct bogus logic for "next" offset of arguments
2845 on stack and adjust for fixed offset of stack arguments.
2847 2012-12-12 Paulo Andrade <pcpa@gnu.org>
2849 * include/lightning.h, lib/jit_arm.c, lib/jit_mips.c,
2850 lib/jit_ppc.c, lib/jit_x86.c, lib/lightning.c: Change jit_prepare
2851 to no longer receive an argument. If receiving an argument, it
2852 should be an ABI specifier, not a boolean if varargs or not,
2853 and add the new jit_ellipsis call, to specify where the
2854 ellipsis is in the C prototype of the function being called.
2855 Note that currently it is not supported to define varargs
2856 functions and it will be ignored if calling jit_ellipsis not
2857 in a prepare/finish* block, but this should be addressed.
2859 * check/allocai.tst, check/alu_add.tst, check/alu_and.tst,
2860 check/alu_com.tst, check/alu_div.tst, check/alu_lsh.tst,

2867 check/ldstxr-c.tst, check/ldstxr.tst, check/rpn.tst,
2868 check/lightning.c: Update for the change to jit_prepare and
2869 addition of jit_ellipsis.
2871 2012-12-11 Paulo Andrade <pcpa@gnu.org>
2873 * lib/jit_ppc-cpu.c: Make movr a function that checks arguments
2874 so that other code can safely assume it is a noop if src and dst
2875 are the same register.
2876 Implement rem{r,i}{,_u} as a div{,u}/mul/sub.
2877 Correct ANDIS, ORIS and XORIS calls to cast the argument to
2878 unsigned before the shift to avoid an assertion if the argument
2879 had the topmost bit set.
2880 Implement lshi, rshi and rshi_u as functions to test for a
2881 zero argument, that would otherwise trigger an assertion when
2882 computing the shift value.
2883 Do a simple implementation of bm{s,c}{r,i} with a temporary,
2884 "andr" of arguments and jump based on comparison with zero.
2885 Correct typo in ldxi_c.
2887 * lib/jit_ppc-fpu.c: Correct wrong arguments to FDIV* and STF*.
2889 * lib/jit_ppc.c: Correct wrong check for 6 instead of 8 integer
2890 arguments in registers. If calling a varargs function and
2891 passing a float or double argument, also either store the
2892 value in the stack or in integer registers, as varargs functions
2893 do not fetch it from float registers.
2894 Add "case" for new functions and incorrectly missing ones.
2895 Call libgcc's __clear_cache, that should know what to do
2896 if the hardware needs flushing cache before execution.
2898 * lib/lightning.c: Do a simple/trivial logic in jit_regset_scan1,
2899 that should make it easier for the compiler to optimize it, and
2900 that also corrects the previously wrong code for big endian, and
2901 that was causing problems in ppc due to not saving all callee save
2902 registers as it was not "finding" them in the regset due to the
2903 little endian assumption bug.
2905 2012-12-11 Paulo Andrade <pcpa@gnu.org>
2907 * configure.ac: Only default to using the builtin disassembler
2908 if on GNU/Linux. This should be temporary, due to requiring
2910 Correctly check $target_cpu for powerpc.
2912 * include/lightning/jit_ppc.h: Correctly implement jit_v_num.
2914 * include/lightning/jit_private.h: Declare proper prototype
2915 for jit_init_debug and jit_finish_debug.
2917 * lib/jit_ppc-cpu.c: Remove code to save/restore callee save
2918 float registers, as it is not required since those float
2919 registers are not usable currently.
2920 Change prolog and epilog generation to, at least comparing
2921 code, match what gcc generates in "gcc -O0", but it is still
2922 failing in Darwin PPC, apparently due to the __clear_cache
2923 call not being enough, as frequently it will also fail to
2924 execute, and the code buffer is all zeroes.
2926 * lib/lightning.c: Do not fail in jit_regset_scan1 calls due
2927 to passing 64 as argument on computers with 64 registers.
2929 2012-12-10 Paulo Andrade <pcpa@gnu.org>
2931 * lib/jit_mips-cpu.c: Correct all current test cases.
2932 Call the "xori" not the "XORI" macro for jit_xori implementation,
2933 as the XORI macro handles only 16 bit unsigned values.
2934 Call the "movr" macro, not the "movi" macro in the special
2935 case of adding or subtracting zero.
2936 Use the proper temporary register in the jit_andr implementation.
2938 2012-12-09 Paulo Andrade <pcpa@gnu.org>
2940 * check/alu.inc, check/alu_add.ok, check/alu_add.tst,
2941 check/alu_and.ok, check/alu_and.tst, check/alu_com.ok,
2942 check/alu_com.tst, check/alu_div.ok, check/alu_div.tst,

2949 check/alux_sub.ok, check/alux_sub.tst, check/branch.ok,
2950 check/branch.tst: New test cases for arithmetic and branch
2953 * check/Makefile.am: Update for new test cases.
2955 * include/lightning/jit_private.h: Make the jit_reg_free_p
2956 macro shared by all backends. Previously was added for the
2957 arm backend, but is useful in the x86_64 backend when checking
2958 state of "special purpose register".
2959 Also add the new jit_class_named register class, that must be
2960 or'ed with the register value if calling jit_get_reg expecting
2961 an specific value, because the specific register value may be
2962 zero, that previously was treated as no register requested.
2964 * lib/jit_arm-cpu.c: Correct argument order for T2_MVN.
2966 * lib/jit_arm-swf.c: Call the proper function for double
2967 divide. The "software float" implementation just calls
2970 * lib/jit_arm.c: Return float/double values in the float
2971 register if using the hard float ABI.
2973 * lib/jit_x86-cpu.c: Change the can_sign_extend_int_p macro
2974 to not include -0x80000000L, because there is code that
2975 "abuses" it and thinks it can negate the immediate value
2976 after calling that macro.
2977 Correct implementation of jit_subi that had a wrong code
2978 patch logic doing subtraction with reversed arguments.
2979 Correct REX prefix calculation in the jit_muli implementation.
2980 Correct logic to get/unget %*ax and %*dx registers in divremr
2982 Correct divremi that was using the symbolic, unique %*ax
2983 value in on place (not using the _REGNO name suffix).
2984 Correct cut&paste error causing it to use "xor" instead of
2985 "or" in one code path of the jit_ori implementation.
2986 Correct several flaws when clobbering registers and/or when
2987 one of the arguments was %*cx in the rotshr wrapper function
2988 implementing most shift operations.
2990 * lib/lightning.c: No longer expect that the backend be smart
2991 enough to know what to do when asking for a named register
2992 if that register is already an argument or is live. It fails
2993 if it is an argument, or if register is live, fails if cannot
2995 No longer incorrectly assume that eqr_{f,d} and ltgr_{f,d} are
2996 safe to inverse value tests in jump thread optimization.
2998 2012-12-05 Paulo Andrade <pcpa@gnu.org>
3000 * check/Makefile.am, check/cvt.ok, check/cvt.tst: Add new
3001 "cvt" test case to test conversion from/to int/float types.
3003 * check/lightning.c: Only define truncr_{f,d}_l in 64 bit mode.
3005 * include/lightning.h: Correct typo that caused it to define
3006 jit_truncr_{f,d}_l in 32 bit mode.
3008 * lib/jit_arm-cpu.c: Avoid assertion failure in the signed/unsigned
3009 extend opcodes generation as it shares an interface for 3 argument
3012 * lib/jit_x86-cpu.c: Correct wrong argument passed to
3013 jit_unget_reg in the andi implementation and wrong byte
3014 unsigned extend code generation.
3016 * lib/jit_x86-sse.c: Correct conversion from "word" to float or
3017 double as is dependent on wordsize.
3019 2012-12-05 Paulo Andrade <pcpa@gnu.org>
3021 * check/ldstr-c.ok, check/ldstr-c.tst, check/ldstxi-c.ok,
3022 check/ldstxi-c.tst, check/ldstxr-c.ok, check/ldstxr-c.tst:
3023 New test case files testing load clobbering the base and/or
3026 * check/ldst.inc: New file with common definition for all the
3029 check/Makefile.am, check/ldsti.tst, check/ldstr.tst,
3030 check/ldstxi.tst, check/ldstxr.tst: Update for new common
3031 definitions file and new register clobber ldst tests.
3033 2012-12-05 Paulo Andrade <pcpa@gnu.org>
3035 * lib/jit_mips-fpu.c: Correct wrong register order in stxr_{f,d}
3036 in the mips backend.
3038 2012-12-05 Paulo Andrade <pcpa@gnu.org>
3040 * lib/jit_arm-vfp.c: Correct regression found in armv7l with
3043 2012-12-05 Paulo Andrade <pcpa@gnu.org>
3045 * check/ldstxi.tst, check/ldstxr.tst: Correct wrong argument
3046 order for 32 bit mode tests.
3048 * configure.ac: Correct check for ix86 target_cpu.
3050 2012-12-05 Paulo Andrade <pcpa@gnu.org>
3052 * check/ldstr.ok, check/ldstr.tst, check/ldsti.ok,
3053 check/ldsti.tst, check/ldstxr.ok, check/ldstxr.tst,
3054 check/ldstxi.ok, check/ldstxi.tst:
3055 New test case files exercising a very large amount of
3056 register combinations to verify load/store implementation.
3058 * check/Makefile.am: Update for new test cases.
3060 * lib/jit_x86-cpu.c: Correct wrong argument order when
3061 computing REX prefix for {ld,st}r_T codes;
3063 2012-12-04 Paulo Andrade <pcpa@gnu.org>
3065 * lib/jit_mips-fpu.c, lib/jit_mips.c: Implement missing mips
3066 jit_sqrtr_{f,d} codes.
3068 * check/all.tst, include/lightning.h, lib/jit_print.c: Change
3069 declaration order and call order in all.tst of {add,sub}c and
3070 {add,sub}x. *c must be called before to set the carry and *x
3071 second to use the carry and keep it set. The wrong call order
3072 was causing all.tst to fail in mips, where a register is
3073 allocated to keep a global carry state.
3075 2012-12-04 Paulo Andrade <pcpa@gnu.org>
3077 * include/lightning/jit_mips.h, lib/jit_mips-cpu.c,
3078 lib/jit_mips-fpu.c, lib/jit_mips.c: Correct float/double
3079 argument handling and make the mips backend pass the initial
3082 * include/lightning.h, ib/jit_print.c, lib/lightning.c:
3083 Add extra enum values for argument handling functions that
3084 could not be abstracted to the current codes, that is, when
3085 float values need to move from/to gpr from/to fpr. It would
3086 be more tempting to add such primitives, but they would have
3087 wordsize limitations, and it is not expected to add codes
3088 with one gpr argument for 64 bit and two for 32 bit.
3090 * lib/jit_ppc.c: Check _jit->function before calling jit_epilog()
3091 to avoid a runtime exception.
3093 2012-12-04 Paulo Andrade <pcpa@gnu.org>
3095 * include/lightning/jit_mips.h, lib/jit_mips.c: Update to
3096 make the mips backend compile in a qemu image.
3098 * lib/jit_ppc.c: Minor adaptations to help in having the
3099 ppc backend compilable.
3101 2012-12-03 Paulo Andrade <pcpa@gnu.org>
3103 * configure.ac, include/lightning/jit_private.h, lib/jit_arm-cpu.c,
3104 lib/jit_arm-swf.c, lib/jit_arm.c, check/Makefile.am: Correct
3105 implementation of the arm backend port to build and pass the
3106 current test cases. Tested on armv7 with softfp abi.
3108 * lib/jit_disasm.c: Rename and change prototype of static
3109 disassemble function as in the arm backend it is required
3110 to access state information stored in the jit_state_t object.
3112 * check/3to2.tst, check/add.tst: Correct test case code assuming
3113 JIT_RO and JIT_RET are the same, and even if they are the same,
3114 the logic was incorrect because it must always call jit_retval*
3115 to fetch a function call return before any other instruction.
3116 The arm backend hash a special condition if jit_retval is not
3117 called, because "r0" is not JIT_R0, but is JIT_RET and *also*
3118 the first argument for a called function, so JIT_RET must be
3119 only used as an argument to jit_retval.
3121 2012-12-03 Paulo Andrade <pcpa@gnu.org>
3123 * check/all.tst, check/lightning.c: Only declare or use 64 bit
3124 interfaces on 64 bit builds.
3126 * check/fib.tst: Use simpler logic to not need preprocessor
3127 conditionals for 32 or 64 bit.
3129 * include/lightning.h: Only declare 64 bit macros on a 64 bit
3130 build. Code using lightning must know about wordsize and the
3131 jit generation limitations, also, this way it generates a
3132 compile time failure, not a runtime assertion.
3134 * include/lightning/jit_x86.h: Correct typo in macro name.
3136 * lib/jit_arm.c, lib/jit_arm-cpu.c, lib/jit_mips.c,
3137 lib/jit_mips-cpu.c, lib/jit_ppc.c, lib/jit_ppc-cpu.c,
3138 lib/jit_x86.c, lib/jit_x86-cpu.c: Correct wrong code to get
3139 current jit function pointer.
3141 * lib/lightning.c: Move call to the simplify() optimization
3142 to after register liveness is known. Previous code did work
3143 by accident but now with proper test cases the problem was
3146 * lib/jit_disasm.c: Always cast bfd_vma to long long when
3147 passing it as printf argument.
3149 2012-12-03 Paulo Andrade <pcpa@gnu.org>
3151 * configure.ac, check/Makefile.am, check/check.sh,
3152 doc/Makefile.am, include/lightning/Makefile.am,
3153 lib/Makefile.am: Correct make distcheck.
3155 2012-12-02 Paulo Andrade <pcpa@gnu.org>
3157 * lib/jit_ppc.c: Assign copyright ownership to FSF.
3159 * lib/jit_x86-cpu.c: Correct integer multiplication that was
3160 generating code with reversed register arguments.
3162 * check/rpn.ok, check/rpn.tst: New test case file.
3164 2012-12-02 Paulo Andrade <pcpa@gnu.org>
3166 * lib/jit_x86-cpu.c, lib/jit_x86-sse.c, lib/jit_x86-x87.c:
3167 Actually change copyright owner to FSF as avertised.
3169 * lib/jit_arm-cpu.c, lib/jit_arm-swf.c,
3170 lib/jit_arm-vfp.c, lib/jit_arm.c,
3171 lib/jit_mips-cpu.c, lib/jit_mips-fpu.c, lib/jit_mips.c,
3172 lib/jit_ppc-cpu.c, lib/jit_ppc-fpu.c, lib/jit_ppc.c: New
3173 files implementing initial code different jit backends.
3175 * include/lightning/jit_private.h: Add extra field to the
3176 private jit_patch_t type, required by the arm port.
3178 * lib/Makefile.am: Update for the new backend implementation
3181 2012-12-02 Paulo Andrade <pcpa@gnu.org>
3183 * check/Makefile.am: Add proper "make clean" rule and missing
3184 check.sh to EXTRA_DIST.
3186 2012-12-02 Paulo Andrade <pcpa@gnu.org>
3188 * .gitignore: Update pattern of ignored files.
3190 * check/Makefile.am: Add rule to build liblightning.la dependency
3191 in case of running "make check" before building the library.
3193 2012-12-02 Paulo Andrade <pcpa@gnu.org>
3195 * lightning/Makefile.am, lightning/asm-common.h,
3196 lightning/core-common.h, lightning/fp-common.h,
3197 lightning/funcs-common.h, lightning/i386/Makefile.frag,

3205 lightning/sparc/asm.h, lightning/sparc/core.h,
3206 lightning/sparc/fp.h, lightning/sparc/funcs.h:
3207 Removed. The core logic is used in the new code, and new mips
3208 and arm ports will be added. At first, sparc will not be
3209 supported as it has not yet been ported to the new engine.
3211 2012-12-02 Paulo Andrade <pcpa@gnu.org>
3213 * tests/Makefile.am, tests/3to2.c, tests/3to2.ok, tests/add.c,
3214 tests/add.ok, tests/allocai.c, tests/allocai.ok, tests/bp.c,
3215 tests/bp.ok, tests/divi.c, tests/divi.ok, tests/fib.c, tests/fib.ok,

3222 tests/rpnfp.ok, tests/sete.c, tests/sete.ok, tests/testfp.c,
3223 tests/testfp.ok, tests-run-test: Removed previous test suite, in
3224 favor of a newer one in the check subdirectory.
3226 * check/3to2.ok, check/3to2.tst, check/add.ok, check/add.tst,
3227 check/allocai.ok, check/allocai.tst, check/bp.ok, check/bp.tst,
3228 check/divi.ok, check/divi.tst, check/fib.ok, check/fib.tst:
3229 New sample input for the new test program, loosely matching
3230 several of the previous test cases.
3232 * check/Makefile.am: New test suite makefile.
3234 * check/check.sh, check/run-test: New wrapper files for the
3237 * check/lightning.c: New file. The main driver of the new test
3238 suite, that compiles to a parser of a very simple assembly like
3239 language, generates jit and executes it.
3241 * check/all.tst: New file. A generic debug and sample test file
3242 with a directive to prevent it from being executed, and useful to
3243 read disassembly of all possible instructions, using a fixed set
3246 * include/Makefile.am, include/lightning.h,
3247 include/lightning/Makefile.am, include/lightning/jit_arm.h,
3248 include/lightning/jit_mips.h, include/lightning/jit_ppc.h,

3252 lib/jit_x86.c, lib/lightning.c: New files. These files are
3253 written from scratch, only by <pcpa@gnu.org>, and have now
3254 copyright assignment to the FSF. This is the core of the new
3255 lightning rework. Previously it was integrated in code with
3256 a garbage collector and several custom types like vectors and
3257 hash tables, so this first code merge with lightning converts
3258 that code into a library extracting only the jit bits, and at
3259 first only for x86_64 GNU/Linux.
3261 * lightning.h, m4/lightning.m4: Removed. These are no longer
3262 required in the new lightning code.
3264 .gitignore, Makefile.am, configure.ac: Update for the new
3267 2012-12-02 Paulo Andrade <pcpa@gnu.org>
3268 * .cvsignore: Removed for extra cleanup.
3270 * build-aux: Rename directory to m4.
3272 * m4: Renamed to "default" name and for consistency with merge
3273 with code rework to be imported in lightning.
3275 * .gitignore, configure.ac, Makefile.am, doc/Makefile.am:
3276 Update for build-aux to m4 rename.
3278 2012-12-01 Paulo Andrade <pcpa@gnu.org>
3280 * opcode/Makefile.am, opcode/Makefile.in, opcode/ansidecl.h,
3281 opcode/bfd.h, opcode/dis-asm.h, opcode/dis-buf.c, opcode/disass.c,
3282 opcode/i386-dis.c, opcode/i386.h, opcode/ppc-dis.c, opcode/ppc-opc.c,
3283 opcode/ppc.h, opcode/sparc-dis.c, opcode/sparc-opc.c, opcode/sparc.h,
3284 opcode/sysdep.h: Removed. Do not bundle GNU binutils files.
3286 * aclocal.m4, configure, Makefile.in, config.h.in, doc/Makefile.in,
3287 lightning/Makefile.in, tests/Makefile.in: Removed. Do not maintain
3288 autogenerated files that also generate too much diff noise when
3291 * build-aux/help2man, build-aux/texinfo.tex, build-aux/texi2dvi:
3292 Removed. Buildenvironment must have an up to date version from
3295 * build-aux/config.guess, build-aux/config.sub, build-aux/depcomp,
3296 build-aux/install-sh build-aux/mdate-sh build-aux/missing: Removed.
3297 Do not maintain a copy of automake files in git. Release tarballs
3298 must use an up to date version.
3300 * lightningize.in, doc/lightningize.1: Removed. Do not encourage
3301 bundling lightning in other packages. It should use a system package
3302 or a proper thirdy part subdirectory.
3304 * INSTALL: Removed. Autoreconf removes it and creates a symlink
3305 when regenerating files, so, avoid conflicts in git and let
3306 automake create the symlink.
3308 * .gitignore: Add INSTALL and autogenerated files.
3310 * configure.ac, Makefile.am: Update for removal of opcode subdir,
3311 auto generated files and lightningize.
3313 * tests/Makefile.am, tests/3to2.c, tests/add.c, tests/bp.c,
3314 tests/fib.c, tests/fibdelay.c, tests/fibit.c, tests/funcfp.c,
3315 tests/incr.c, tests/printf.c, tests/rpn.c, tests/rpnfp.c,
3316 tests/sete.c, tests/testfp.c: Update for removal of opcode subdir.
3318 * doc/Makefile.am: Update for removal of lightningize.
3320 * configure.ac, lightning/ppc/funcs.h, lightning/sparc/funcs.h,
3321 lightning/i386/fp.h, lightning/i386/core.h, lightning/i386/asm.h,
3322 tests/3to2.c, tests/add.c, tests/bp.c, tests/fib.c, tests/fibdelay.c,
3323 tests/fibit.c, tests/funcfp.c, tests/incr.c, tests/printf.c,
3324 tests/rpn.c, tests/rpnfp.c, tests/sete.c, tests/testfp.c:
3325 Remove LIGHTNING_CROSS, it is half supported and incomplete.
3327 * tests/3to2.c, tests/funcfp.c, tests/rpnfp.c: Remove preprocessor
3328 check on JIT_FPR. If no hardware registers are available, the backend
3329 must provide an alternative for software float.
3331 * lightning/ppc/core.h, lightning/sparc/core.h, tests/Makefile.am:
3332 Remove JIT_NEED_PUSH_POP. It is absolutely not trivial to implement
3333 properly on some backends due to stack alignment constraints, and
3334 whenever it is required, using jit_allocai and using a properly
3335 aligned stack vector, or a heap buffer, is better.
3337 * tests/push-pop.c, tests/push-pop.ok: Removed due to
3338 JIT_NEED_PUSH_POP no longer available.
3340 2011-02-28 Paolo Bonzini <bonzini@gnu.org>
3342 * lightning/i386/core-64.h: Add jit_add{c,x}{i,r}_l, jit_mulr_{l,ul}_,
3343 fix jit_mul{i,r}_{l,ul}.
3345 2010-08-20 Paolo Bonzini <bonzini@gnu.org>
3347 * lightning/i386/fp-64.h: Return patch address from jit_bXYr_{f,d}.
3348 Reported by Paulo César Pereira de Andrade.
3349 * lightning/ppc/fp.h: Likewise.
3350 * lightning/sparc/fp.h: Implement FP branches.

3359 Reported by Paulo César Pereira de Andrade.
3361 2010-08-15 Paolo Bonzini <bonzini@gnu.org>
3363 * tests/ldst.c: Update.
3364 * tests/Makefile.am: Use -ffloat-store to compile it.
3366 2010-08-15 Paolo Bonzini <bonzini@gnu.org>
3368 * lightning/i386/core.h (jit_ldr_c, jit_ldxr_c, jit_ldr_s,
3369 jit_ldxr_s): Move...
3370 * lightning/i386/core-32.h: ... here.
3371 * lightning/i386/core-64.h (jit_ldr_c, jit_ldxr_c, jit_ldr_s):
3372 Use movsbq and movswq.
3374 2010-08-10 Paulo César Pereira de Andrade <pcpa@mandriva.com.br>
3376 * lightning/i386/core-32.h (jit_replace): Use MOVLrr, not MOVLir.
3377 (jit_movbrm): Check index register as well.
3378 * lightning/i386/fp-64.h: Add jit_extr_f_d and jit_extr_d_f.
3379 * lightning/fp-common.h: Add jit_extr_f_d and jit_extr_d_f.
3381 2010-07-28 Paolo Bonzini <bonzini@gnu.org>
3383 * tests/Makefile.am: Add ldst test.
3384 * tests/Makefile.in: Regenerate.
3385 * tests/ldst.c: New.
3386 * tests/ldst.ok: New.
3388 2010-07-28 Paolo Bonzini <bonzini@gnu.org>
3390 * THANKS: Add Paulo Cesar Pereira de Andrade.

3416 * lightning/i386/core-64.h: Use Mike's macros for x86-64 too.
3417 * lightning/i386/core.h: Remove jit_replace.
3419 2009-02-27 Mike Spivey <mike@comlab.ox.ac.uk>
3421 * lightning/i386/core.h: Rewrite shift-handling macros.
3422 * lightning/fp-common.h: Fix jit_extr_{f_d,d_f}.
3424 2009-02-17 Mike Spivey <mike@comlab.ox.ac.uk>

3432 2009-02-17 Paolo Bonzini <bonzini@gnu.org>
3434 * lightning/fp-common.h: Define double branches if missing.
3435 * lightning/i386/asm.h: Define JC and JNC mnemonics.
3436 * lightning/i386/fp-32.h: Fix jit_fp_btest. All reported
3439 2008-10-09 Paolo Bonzini <bonzini@gnu.org>
3441 * lightning/ppc/funcs.h (jit_flush_code): Subtract 1 from end.
3442 Reported by Eli Barzilay and Matthew Flatt.
3444 2008-08-23 Nix <nix@esperi.org.uk>
3446 * lightning/i386/Makefile.frag: fp-32.h and fp-64.h are target files.
3448 2008-07-02 Laurent Michel <ldm@engr.uconn.edu>
3450 * lightning/ppc/funcs.h (jit_flush_code): modified the computation
3451 of start/end. The pointer arithmetic was done without casting. It
3452 prevented compilation with recent gcc versions.
3453 * lightning/ppc/core.h (jit_pushr_i): The offset for the store was
3454 incorrect. Should have been 4 bytes below SP (not above).
