30 * lib/jit_print.c: Print debug output for the new instructions.
31 * lib/lightning.c: Add logic for the new register pair in the
32 'v' (second) field of jit_node_t. The new pattern is required
33 to allow having a 'double' immediate in the last argument, for
34 the versions with immediates. The versions with immediates are
35 added for consistency, as they should be very rarely used in
36 common usage of fused multiply add/sub.
38 2023-04-06 Paulo Andrade <pcpa@gnu.org>
40 * include/lightning.h.in: Define new movi_w_f, movi_w_d and

51 are required by unldr_x and unstr_x in some code paths.
52 * lib/lightning.c: Implement generic movi_f_w, movi_d_w and
53 movi_d_ww that are actually the same for all ports.

68 * check/all.tst: Add missing instructions to debug encoding.
69 * check/lightning.c: Implement calls to the new rich set of
70 instructions, with an immediate argument, mostly which are resolved
71 at code generation time. With the exception of jit_negi_{f,d},
72 jit_absi{f,d} and jit_sqrti_{f,d} that generate code to execute at
73 runtime. This is required because the code generator should create
74 the proper float environment with rounding modes, exceptions, etc.
75 The new jit_depi is just a wrapper to have the second operand as an
76 immediate and call jit_depr.
77 * include/lightning.h.in: Declare new instructions code and function
78 prototypes as appropriate.
79 * include/lightning/jit_private.h: Add 4 new macros to generate
80 synthetic debug for float operations with an immediate argument.

84 Add code to call the generic code to implement new instructions
85 with immediate operands.
86 * lib/jit_names.c, lib/jit_print.c: Add debug for the new instructions
87 with immediate operands.

116 lroti, rrotr and rroti.
117 * lib/jit_hppa-cpu.c, lib/jit_hppa.c: Implement optimized rroti.
118 Other instructions use fallbacks.
119 * lib/jit_loongarch-cpu.c, lib/jit_loongarch.c: Implement optimized
120 rrotr and rroti. lrotr and lroti just adapt arguments and use a
122 * lib/jit_mips-cpu.c, lib/jit_mips.c: If mips2, Implement optimized
123 rrotr and rroti. lrotr and lroti just adapt arguments and use a
124 right shift. If mips1 use fallbacks.
125 * lib/jit_ppc-cpu.c, lib/jit_ppc.c, jit_s390-cpu.c, jit_s390.c,
126 lib/jit_x86-cpu.c, lib/jit_x86.c: Implement optimized lrotr,
128 * lib/jit_fallback.c: Implement fallbacks for lrotr, lroti,
129 rrotr and rroti. Also add extra macro to avoid segfaults in s390,

139 popcntr using the fpu.
140 * lib/jit_alpha-cpu.c, lib/jit_alpha.c: Implement optimized
141 popcntr using the ctpop instruction.
142 * lib/jit_arm-vfp.c, lib/jit_arm-cpu.c, lib/jit_arm.c: Implement

157 2023-02-26 Paulo Andrade <pcpa@gnu.org>
159 * check/bit.tst: Correct 32 bit sample ctz implementation.
160 * include/lightning/jit_mips.h: Add jit_cpu flags for instructions
161 that cannot be used in delay slot.
162 * lib/jit_fallback.c: Mips fallbacks now might need a flush of
163 instructions to get correct label addresses, due to pending
164 instruction candidate to delay slot.
165 * lib/jit_mips-cpu.c: Flush any pending instruction if it cannot
166 be used in the delay slot. Add calls to fallback clo, clz, cto and
168 * lib/jit_mips.c: Add code to set defaults or detect if can use
169 certain instructions to delay slots.
171 2023-02-23 Paulo Andrade <pcpa@gnu.org>
173 * include/lightning/jit_private.h: Add new 'inst' field to
174 jit_compiler_t, if __mips__ is defined. This field is a simple
175 helper for a pending instruction to be emitted, and that can
176 be emitted out of order.
177 * lib/jit_fallback.c: Update for changes in internal mips patching
178 and jumping macros and function calls.

218 * lib/jit_x86-cpu.c, lib/jit_x86-sse.c, lib/jit_x86.c: Implement
219 %rip relative addressing when reliable. Currently disabled for
220 x32 and _WIN32; could be added for positive relative addresses
221 only where it should work.
222 * lib/lightning.c: Correct problem added in previous patch due
223 to not testing on a 32 bit environment.
225 2023-01-23 Paulo Andrade <pcpa@gnu.org>
227 * lib/jit_mips-cpu.c, lib/jit_mips-cpu.c: Use pseudo instructions
228 "b" (BEQ(0,0,disp)) and "bal" (BGEZAL(0,disp)) for mips2, when an
229 unconditional branch or function call is known to be in range of a
230 relative jump. This should significantly reduce jit size generation.
232 2023-01-20 Paulo Andrade <pcpa@gnu.org>
234 * lib/jit_mips-cpu.c, lib/jit_mips.c, lib/jit_rewind.c: Adapt
235 code to implement a variable framesize and optimize frame pointer
236 for simple leaf functions.
238 2023-01-19 Paulo Andrade <pcpa@gnu.org>
240 * lib/jit_riscv.c, lib/jit_riscv-cpu.c: Adapt code to use a
241 variable framesize. Previously it was aligning the stack at
242 8 bytes, not 16. Now functions are called with a 16 byte aligned
245 2023-01-18 Paulo Andrade <pcpa@gnu.org>
247 * include/lightning/jit_private.h: Include new framesize field
248 of jit_compiler_t; add new alist field for jit_function_t; add
249 new cvt_offset and need_stack fields specific to x86.
250 * lib/jit_x86.c, lib/jit_x86-cpu: Rewrite code to create stack
251 frames, so that less stack space can be used if no, or very few
252 callee save registers are modified in a function.
253 * jit_x86-sse.c, jit_x86-x87.c: Make CVT_OFFSET variable, and
254 dynamically allocated; this is required to avoid needing to
255 modify twice %rsp at function prologs, even if no stack space
258 2022-11-09 Paulo Andrade <pcpa@gnu.org>
260 * configure.ac: Add new --enable-devel-strong-type-checking
262 * include/lightning.h.in: Rework to not need to know if
263 PACKED_STACK is defined, and add a new argument to _jit_arg,
264 _jit_putarg{r,i}, _jit_pusharg{r,i} and _jit_ret{r,i} to have
265 the same code path if PACKED_STACK is defined or not, and also
266 to implement STRONG_TYPE_CHECK enabled with the new
267 --enable-devel-strong-type-checking.
268 * include/lightning/jit_private.h: Add new macros to add assertions
269 for STRONG_TYPE_CHECK and avoid pasting tokens in jit_inc_synth*
270 when the token is not a static known value.
271 * lib/jit_aarch64.c: The first implementation of the new code,
272 working correctly in Apple M1 and with and without STRONG_TYPE_CHECK
275 2022-11-08 Paulo Andrade <pcpa@gnu.org>
277 Add support for packed stack arguments as used by Apple M1
278 aarch64 cpus. This requires a major redesign in how Lightning
279 works, because contrary to all other supported ports, in this
280 case arguments must be truncated and sign/zero extended if
281 passed in registers, but when receiving the argument, there
282 is no need to truncate and sign/zero extend.
283 Return values are also treated this way. The callee must
284 truncate sign/zero extend, not the caller.
285 check/Makefile.am: Add LIGHTNING_CFLAGS to AM_CFLAGS.
286 check/all.tst: Implement paired arg/getarg/pusharg/putarg/ret
287 codes to validate they do not generate assertions.

289 check/stack.tst: Update to pass in all build types.
290 check/lightning.c: Add new codes for extra codes to handle
292 * configure.ac: Add a preprocessor define to know if packed stack
293 need is required. This is not really used, as it was moved to
295 * doc/Makefile.am: Add LIGHTNING_CFLAGS to AM_CFLAGS.
296 * doc/rpn.c: Update to pass in all build types.
297 include/lightning.h.in: Add new codes and reorder enum.

380 2022-10-04 Paulo Andrade <pcpa@gnu.org>
382 * include/lightning/jit_private.h: Add new flag to jit_block_t.
383 * lib/lightning.c: Rewrite register liveness and state at block
384 entry code to avoid a very expensive and non scaling code path.
385 Now it attempts to do as few as possible recomputations when
386 merging state of adjacent blocks, still doing one extra nop pass
387 (in the sense that it will not find any changes) to make sure the
390 2022-09-30 Paulo Andrade <pcpa@gnu.org>
392 * include/lightning/jit_private.h: Implement new data structures
394 * lib/jit_disasm.c: Extra disassemble code for riscv constant pool.
395 * lib/jit_riscv-cpu.c: Modify movi to use constant pool if 3 or
396 more instructions are required to construct constant and modify
397 movi_p to use a pc relative load from a constant pool.
398 lib/jit_riscv-sz.c: Update for new constant pool code. Most

416 needing a fallback compare and swap.
417 * include/lightning/jit_private.h: Add support for a register pair
418 in second argument. Required by the new casr and casi operations.

432 lib/jit_sparc-cpu.c, lib/jit_sparc-sz.c, lib/jit_sparc.c: Implement
433 fallback compare and swap with pthreads. At least some of these
434 should be updated for inline code generation.
435 * lib/jit_names.c, lib/jit_print.c: lib/lightning.c: Update for the
436 new compare and swap operation.
437 * doc/body.texi: Add simple documentation of the compare and swap

451 lib/jit_s390-cpu.c, lib/jit_sparc.c, lib/jit_sparc-cpu.c:
452 Implement fallback jit_mov{n,z}r. These are a somewhat cheap
453 implementation, but should be reviewed for the arches that already
454 have a proper conditional move.
455 * lib/jit_arm-sz.c, lib/jit_mips-sz.c: Add missing maximum size
456 estimative and reorder.
457 * lib/jit_aarch64-sz.c, lib/jit_x86-sz.c, lib/jit_ppc-sz.c:
458 Reorder entry to match definition order.
459 * lib/jit_aarch64-sz.c, lib/jit_alpha-sz.c, lib/jit_hppa-sz.c,
460 lib/jit_ia64-sz.c, lib/jit_riscv-sz.c, lib/jit_s390-sz.c,
461 lib/jit_sparc-sz.c: Add heuristic value, basically the sum of
462 the cost of a movr + beqr.
463 * lib/jit_names.c: Add entries for debug output of mov{n,z}r.
464 * lib/lightning.c: Use proper bitmask in jit_classify.
466 2021-04-03 Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de>
468 * check/Makefile.am: Add test for the live instruction.
469 * check/live.ok: New file.
470 * check/live.tst: New file.
471 * doc/body.texi: Add documentation for the live instruction and
472 for jit_get_reg/jit_get_unreg. Fix menu entries.
473 * include/lightning.h.in (jit_get_reg, jit_unget_reg): Expose the
474 macros in the public header file.
475 * include/lightning/jit_private.h (jit_get_reg, jit_unget_reg):
476 Remove the macros from the private header file.
478 2021-04-03 Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de>
480 * Makefile.am, check/Makefile.am, doc/Makefile.am,
481 lib/Makefile.am: Include $(top_builddir)/include in include paths
482 for the autoconf-generated header file lightning.h.
484 2021-04-03 Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de>
486 * doc/.gitignore: Add version.texi to list of ignored files.
487 * doc/version.texi: Remove file from version control.
489 2020-18-04 Paulo Andrade <pcpa@gnu.org>
491 * lib/jit_x86-cpu.c, lib/jit_x86.c: Implement %rip relative
492 calls and jumps on x86_64. Currently very conservative, assuming
493 a jit block can be larger than 2G, so, if a jump or call is in
494 the same jit generation, but target is unknown, use an indirect
495 branch (could have an option to assume a jit code block is
496 never larger than 2G). Also a deoptimization is that now does
497 not always generate ip relative jmpi; previously implicitly
498 assumed jmpi would never be larger than 2G. Overall still an
501 2020-23-01 Paulo Andrade <pcpa@gnu.org>
503 * lib/lightning.c: Add a proper fix to the condition of considering
504 a register dead at entry of a block when it modifies the register
505 !after! a branch to a target where it is live.
506 The correction is just to split blocks on branches. It uses an
507 extra label per branch, but makes following the code simpler and
508 avoid costly searches.
510 2020-22-01 Paulo Andrade <pcpa@gnu.org>
512 * lib/lightning.c: Correct a special condition of a register
513 only assigned in a block, and incorrectly marked as dead before
514 a jump where the register is live.
516 2019-10-04 Paulo Andrade <pcpa@gnu.org>
518 * check/lightning.c, include/lightning/jit_private.h,
519 include/lightning/jit_x86.h, lib/jit_x86-cpu.c, lib/jit_x86-sz.c,
520 lib/jit_x86.c: Correct issues with MinGW64 that defines _WIN32
521 and needs long long for jit_word_t.
523 2019-09-16 Paulo Andrade <pcpa@gnu.org>
525 * lib/lightning.c: Do not add registers that are never modified
526 to the set of registers to scan for live range, what might
527 consume a lot of cpu time, doing nothing.
529 2019-09-16 Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de>
531 * include/lightning/jit_x86.h, lib/jit_x86.c: Correct x86_64
532 backend, made %r12 a callee-save register as dictated by the
535 2019-09-16 Paulo Andrade <pcpa@gnu.org>
537 * Makefile.am: Do not force CFLAGS for the get_jit_size target.
538 * check/lightning.c: Drop __ppc__ check.
539 * include/lightning.h.in: Drop __ppc__ check. Add new
540 jit_flag_vararg flag, for special case in powerpc 32 bit using
541 the SYSV abi, and need to pass an extra argument during code
543 * include/lightning/jit_ppc.c: Drop __ppc_ check. Remove the
544 ABI_ELFv2 macro, as it now directly checks for the _CALL_ELF
545 value when/if appropriate.
546 * include/lightning/jit_private.h: Drop __ppc_ check. Check for
547 _CALL_AIXDESC to define extra data to handle function
549 * lib/jit_ppc-cpu.c: Update to check for _CALL_SYSV; assume
550 !_CALL_SYSV == (_CALL_AIX || _CALL_LINUX). Significant code
551 rework for the SYSV abi.
552 * lib/jit_ppc-sz.c: Update for the SYSV abi.
553 * lib/jit_ppc.c: Update for the SYSV abi. Add matching va_list
554 type. Drop __ppc__ check.
555 * lib/jit_size.c: Drop __ppc_ check.
556 * lib/lightning.c: Drop __ppc__ check. Add proper check for
557 __powerpc__ and _CALL_AIXDESC to manage function descriptors.
558 * lib/size.c: Update to drop __pppc_ check and SYSV abi.
560 2019-08-30 Paulo Andrade <pcpa@gnu.org>
562 * lib/jit_mips-cpu.c: Use JALR to get the same effect as JR, as
563 in mips32r6 JR generates an illegal instruction. Thanks to
564 Bruno Haible for providing a patch and the information, reported at
565 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=925129
568 2019-08-29 Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de>
570 * include/lightning/jit_private.h: Move definition of offsetof
571 from the public header file here.
573 * configure.ac, include/Makefile.am, include/lightning.h,
574 include/lightning.h.in: Generate lightning.h from lightning.in.h
575 and remove the dependence on config.h from the public header file.
577 2019-06-04 Paulo Andrade <pcpa@gnu.org>

580 lib/jit_riscv-fpu.c, lib/jit_riscv-sz.c, lib/jit_riscv.c:
581 Implement riscv port. Only 64 bit Linux supported. Built on

587 Minor updates for the new riscv port.
589 2019-06-04 Paulo Andrade <pcpa@gnu.org>
591 * lib/jit_alpha.c lib/jit_ia64.c lib/jit_mips.c lib/jit_sparc.c:
592 Correct assertion of _jitc->regarg after emiting an instruction.
593 jit_carry may be set, but not an argument to the current instruction.
595 2019-06-01 Paulo Andrade <pcpa@gnu.org>
597 * lib/lightning.c: Correct assertion on jit_unget_reg when the
598 argument is jit_carry, and jit_carry was not used in the
601 2019-06-01 Paulo Andrade <pcpa@gnu.org>
603 * include/lightning/jit_private.h: Remove no longer need
604 setmask field of jit_block_t and blockmask from jit_compiler_t.
606 * lib/lightning.c: Rework of register live and unknown state
607 information during jit generation. It no longer recurses nor
608 do dangerous bit unset of registers in unknown state. The
609 only pitfall known, that must be taken care now is that jmpr
610 (or jmpi to not a jit node) is treated as a function call, as
611 otherwise it would need to consider all registers live, and
612 spill/reload during all jit generation.
614 2018-12-28 Paulo Andrade <pcpa@gnu.org>
616 * lib/jit_disasm.c: Release bfd handle. Thanks for patch to
617 Marc Nieper-Wißkirchen.
619 2018-08-30 Paulo Andrade <pcpa@gnu.org>
621 * lib/jit_disasm.c: Add hints to select hppa disassembler.
623 * lib/jit_hppa-cpu.c: Correct address of vastart when all
624 argument registers were used as non vararg arguments.
626 * lib/jit_hppa-fpu.c: Disable load/store of rv,ix,rb where
627 rv is the value, ix is an register or integer offset and rb
628 is a base register. These should be better tested, as they do
629 not work on all environments (fail on qemu-hppa).
631 2018-04-20 Paulo Andrade <pcpa@gnu.org>
633 * include/lightning/jit_private.h: Add new register classes to
634 flag float registers and double only registers, required for sparc64
635 where only low 32 bit fpr registers can be used for single precision
637 Add new 128 bit jit_regset_t type for sparc64 register set.
639 * include/lightning/jit_sparc.h, lib/jit_sparc-cpu.c, lib/jit_sparc-fpu.c,
640 lib/jit_sparc-sz.c, lib/jit_sparc.c: Update for 64 bits sparc.
642 * lib/lightning.c: Update for new jit_regset_t required for sparc64.
644 2018-02-26 Paulo Andrade <pcpa@gnu.org>
646 * check/lightning.c, include/lightning.h: Add the new jit_va_push
647 interface. That should be called when passing a va_list to a C
648 function. This is required because on Alpha a va_list is passed
649 by value, and lightning does not know about data types, so, cannot
650 understand it is pushing a va_list as argument.
652 * lib/jit_names.c, lib/lightning.c: Minor changes for the new
655 * check/cva_list.c: Update only test case using jit_va_push, to
656 pass a va_list to a C function.
658 doc/body.texi: Better documentation of the varargs interface.
660 * jit_alpha.c, jit_alpha-cpu.c: Update to properly push a
661 C va_list and correctly calculate varargs offset.
663 * lib/jit_aarch64-sz.c, lib/jit_aarch64.c, lib/jit_alpha-sz.c,

668 Update for the new jit_va_push interface.
670 2018-02-22 Paulo Andrade <pcpa@gnu.org>
672 * lib/jit_alpha-cpu.c: Always set t12 to the address of the
673 current function, to properly work on all systems. Previously
674 the shortcut did only work on Tru64. For Linux and glibc the
677 2018-02-22 Paulo Andrade <pcpa@gnu.org>
679 * lib/jit_aarch64.c, lib/jit_alpha.c, lib/jit_arm.c,
680 lib/jit_mips.c, lib/jit_ppc.c, lib/jit_sparc.c, lib/jit_x86.c:
681 Correct wrong logic in usage of jit_live in jit_retr. The
682 problem is that if a temporary is required during epilog,
683 the return register might be allocated, so, jit_live must always
686 2018-01-31 Paulo Andrade <pcpa@gnu.org>
688 * lib/lightning.c: Avoid deep recursions when computing live
691 2018-01-31 Paulo Andrade <pcpa@gnu.org>
693 * lib/jit_mips-cpu.c: Correct frame size and varargs
694 initialization for the n32 abi.
695 * lib/jit_mips.c, lib/jit_mips-fpu.c: Correct 32 bit abis
698 2017-09-13 Paulo Andrade <pcpa@gnu.org>
700 * configure.ac: Add check for binutils 2.29 prototype to the
701 disassembler function.
702 * lib/jit_disasm.c: Adapt for binutils 2.29 change.
704 2017-06-09 Paulo Andrade <pcpa@gnu.org>
706 * include/lightning/jit_private.h, lib/lightning.c: Add a
707 second pass from start when computing register live ranges.
708 This should be used temporarily, and is required for certain
709 loop constructs, with several consecutive blocks not referencing
712 2016-05-05 Paulo Andrade <pcpa@gnu.org>
714 * lib/lightning.c: Correct wrong movr simplification,
715 remove no longer needed code to set return registers live
716 and update live register set when reaching a label boundary,
717 but do not descend if the block has been already visited.
718 The later need some tuning for complex code generation, where
719 it will still have issues.
721 2015-11-30 Paulo Andrade <pcpa@gnu.org>
723 * doc/body.texi: Change documentation to no longer say
724 it is a variant of the Fibonacci sequence, and document
725 a proper implementation.
726 Thanks to Jon Arintok for pointing out that the Fibonacci
727 sequence generation was incorrect. It was documented, but
730 * check/fib.tst, check/fib.ok, check/bp.tst, check/bp.ok,
731 doc/ifib.c, doc/rbif.c: Implement a proper Fibonacci
732 sequence implementation.
734 2015-07-03 Paulo Andrade <pcpa@gnu.org>
736 * lib/jit_mips-cpu.c: Correct definition of htonr_ul.
737 Correct prolog/epilog/va* routines to work on o64 abi.
739 * lib/jit_mips-fpu.c: Correct load of double literal
740 argument when not using a data buffer.
741 Remove alignment correction in vaarg_d if using the
744 * lib/jit_mips.c: Correct code to allow creating variadic
745 jit functions when using the new mips abi.
747 * lib/jit_rewind.c: Minor adjust for rewind when using
748 the new mips abi, if there are varargs arguments in
751 2015-06-06 Paulo Andrade <pcpa@gnu.org>
753 * lib/jit_ia64-cpu.c: Search backward for the last output
754 register used, otherwise would stop too early if a float
755 argument used the slot.
756 Correct offset of first va_list argument, and use proper
759 * lib/jit_ia64-fpu.c: Add new functions to move a gpr
760 to a fpr register, to counterpart the ones that move a
761 fpr to a gpr. These are required to properly implement
762 jit_getarg*_{f,d} on complex prototypes, or variadic
765 * lib/jit_ia64-sz.c: Update for support to jit variadic
768 * lib/jit_ia64.c: Implement proper abi for variadic
771 2015-06-04 Paulo Andrade <pcpa@gnu.org>
773 * lib/jit_rewind.c: New file implementing generic functions
774 to "rewind", or rewrite IR code sequences.
776 * include/lightning.h: Add several new codes, that previously
777 were a function call, that would synthesize the operation.
778 Now, there is a code for the operation, and a new flag to
779 know an operation is synthesized.
781 * include/lightning/jit_private.h: Add several new macros to
782 help construct synthesized IR code sequences.
784 * lib/Makefile.am: Update for lib/jit_rewind.c.
786 * lib/jit_disasm.c: Update for a small rework on jit_node_t,
787 so that --enable-devel-disassembler does not need a change
788 in the layout of jit_node_t.
790 * lib/jit_names.c: Update for the new codes.
792 * lib/jit_print.c: Update to print more readable output, and
793 flag synthesized IR code sequences.
795 * lib/jit_aarch64-sz.c, lib/jit_aarch64.c,
796 lib/jit_arm-sz.c, lib/jit_arm.c, lib/jit_x86-sz.c,
797 lib/jit_x86.c: Update for new synthesized IR code sequences.
799 * lib/jit_ppc-cpu.c, lib/jit_ppc-fpu., lib/jit_ppc-sz.c,
800 lib/jit_ppc.c, lib/jit_mips-cpu.c, lib/jit_mips-fpu.c,

802 lib/jit_s390-sz.c, lib/jit_s390.c: Update for new synthesized
803 IR code sequences and correct bugs in the initial varargs
804 implementation support.
806 * lib/jit_alpha-sz.c, lib/jit_alpha.c, lib/jit_hppa-sz.c,
807 lib/jit_hppa.c, lib/jit_ia64-sz.c, lib/jit_ia64.c,
808 lib/jit_sparc-sz.c, lib/jit_sparc.c: Add generic, untested
809 support for the new synthesized IR code sequences. Known
810 most likely broken right now, and should be corrected once
811 access to these hosts is available.
813 * lib/lightning.c: Update for new IR codes, and add support
814 for not yet existing instructions that change third argument.
816 * size.c: Change to use different tables for LE and BE PowerPC.
817 Correct a wrong endif for x32.
819 2015-05-25 Paulo Andrade <pcpa@gnu.org>
821 * check/cva_list.c: New file implementing a test to ensure
822 the value returned by jit_va_start is a valid C va_list.
824 * check/va_list.ok: New simple helper file, as now the
825 va_list.tst test is enabled.
827 * check/va_list.tst: Rewritten for an extensive variadic
830 * check/Makefile.am: Update for the new tests.
832 * lib/jit_arm-cpu.c, lib/jit_arm-swf.c, lib/jit_arm-vfp.c,
833 lib/jit_arm.c: Correct broken software float in a previous
834 commit. Note that the hard float abi implementation is known
835 broken at this time, for special cases involving variadic
836 functions, and should be corrected next.
838 lib/jit_x86-cpu.c, lib/jit_x86-sz.c, lib/jit_x86.c: Correct
839 the jit_va_list_t semantics to match C va_list.
841 2015-05-24 Paulo Andrade <pcpa@gnu.org>
843 * lib/Makefile.am: Bump library major. This is a preparation
844 for a rework that was due for quite some time, but that is
845 now required to properly implement variadic jit functions.
846 The rework is mainly required to know at prolog parsing, if
847 a function is variadic or not. This will benefit a few
848 backends, and is mandatory for the hard float arm abi.
849 The rework was already planned for quite some time, to
850 be able to use a variable stack framesize, and for leaf
851 functions optimization where applicable.
852 The change will be source compatible, but will change
853 some internals, and jit_code_t values, as some new will
855 The only behavior change is that, jit_arg_register_p may
856 change return value on hard float arm abi, if called before
857 or after jit_ellipsis. Common sense anyway, would say to
858 make that call after jit_ellipsis, but documentation
859 should be updated for it.
861 2015-05-24 Paulo Andrade <pcpa@gnu.org>
863 * lib/jit_aarch64-fpu.c, lib/jit_aarch64.c: Correct base
864 aarch64 varargs code.

889 Add base support to jit vararg functions to the ia64 backend.
891 2015-05-10 Paulo Andrade <pcpa@gnu.org>
893 * lib/jit_ia64-fpu.c, lib/jit_ia64.c: Correct movi_d_w
894 and movi_f_w implementation to work when not using a
895 data buffer. This causes the check varargs.tst to
896 work when passing "-d" to the lightning test tool.
898 2015-05-10 Paulo Andrade <pcpa@gnu.org>
900 * lib/jit_ia64.c: Implement inline assembly cache flush,
901 required on multiprocessor systems.
903 2015-05-06 Paulo Andrade <pcpa@gnu.org>
905 * lib/jit_mips-cpu.c, lib/jit_mips-fpu.c, lib/jit_mips.c:
906 Add base support to jit vararg functions to the mips backend.
907 Currently only supported on the o32 abi, until access to a
908 n32 system is arranged.
910 2015-05-05 Paulo Andrade <pcpa@gnu.org>
912 * lib/jit_ppc-cpu.c, lib/jit_ppc-fpu.c, lib/jit_ppc.c:
913 Add base support to jit vararg functions to the PowerPC backend.
915 2015-05-02 Paulo Andrade <pcpa@gnu.org>

924 functions to the arm backend.
926 2015-04-30 Paulo Andrade <pcpa@gnu.org>
928 * lib/jit_aarch64-cpu.c, lib/jit_aarch64-fpu.c,
929 lib/jit_aarch64.c: Add base support to jit vararg
930 functions to the aarch64 backend.
932 2015-04-27 Paulo Andrade <pcpa@gnu.org>
934 * include/lightning.h, include/lightning/jit_private.h,
935 lib/jit_names.c, lib/lightning.c: Add initial support
936 for the new jit_va_start, jit_va_arg, jit_va_arg_d, and
937 jit_va_end interfaces. The jit_va_start call is supposed
938 to return a va_list compatible pointer, but not yet
939 decided if it will be "declared" stdarg compatible,
940 as for now only x86 support has been added (and should
941 be compatible), but issues may arise on other backends.
943 * check/lightning.c: Add wrappers to call the new jit_va_*
946 * lib/jit_x86-cpu.c, lib/jit_x86.c: Implement the new
949 * lib/jit_x86-sz.c: Add fields, but not yet fully updated,
950 as this is an intermediate commit.
952 * lib/jit_aarch64-sz.c, lib/jit_aarch64.c,
953 lib/jit_alpha-sz.c, lib/jit_alpha.c,
954 lib/jit_arm-sz.c, lib/jit_arm.c,
955 lib/jit_hppa-sz.c, lib/jit_hppa.c,
956 lib/jit_ia64-sz.c, lib/jit_ia64.c,
957 lib/jit_mips-sz.c, lib/jit_mips.c,
958 lib/jit_ppc-sz.c, lib/jit_ppc.c,
959 lib/jit_s390-sz.c, lib/jit_s390.c,
960 lib/jit_sparc-sz.c, lib/jit_sparc.c: Prepare for the
961 new jit_va_* interfaces. Not yet implemented, and will
962 cause an assertion if used.
964 * check/va_list.tst: Simple early test case, that works
965 on x86_64, x32, ix86, cygwin, and cygwin64.
967 2015-02-17 Paulo Andrade <pcpa@gnu.org>
969 * include/lightning.h, include/lightning/jit_private.h,
970 lib/jit_aarch64-cpu.c, lib/jit_aarch64.c,
971 lib/jit_alpha-cpu.c, lib/jit_alpha.c,
972 lib/jit_arm-cpu.c, lib/jit_arm.c,
973 lib/jit_hppa-cpu.c, lib/jit_hppa.c,
974 lib/jit_ia64-cpu.c, lib/jit_ia64.c,
975 lib/jit_mips-cpu.c, lib/jit_mips.c,
976 lib/jit_ppc-cpu.c, lib/jit_ppc.c,
977 lib/jit_s390-cpu.c, lib/jit_s390.c,
978 lib/jit_sparc-cpu.c, lib/jit_sparc.c,
979 lib/jit_x86-cpu.c, lib/jit_x86.c: Implement the new
980 jit_allocar(offs, size) interface, that receives
981 two integer registers arguments, allocates space
982 dynamically in the stack, returns the offset in
983 the first argument, and uses the second argument
984 for the size in bytes of the memory to be allocated.
986 * check/allocar.ok, check/allocar.tst: New files
987 implementing test cases for the new jit_allocar
990 * check/Makefile.am, check/lightning.c: Update for
991 the new test case and interface.
993 * doc/body.texi: Add documentation of the new
996 2015-02-17 Paulo Andrade <pcpa@gnu.org>
998 * include/lightning/jit_x86.h, lib/jit_x86-cpu.c,
999 lib/jit_x86-x87.c: No longer make st(7) available.
1000 Need to keep one x87 slots empty to avoid exceptions.
1001 This has the side effect of no longer needing the
1002 hackish emms instruction before a function call.
1004 2015-02-16 Paulo Andrade <pcpa@gnu.org>
1006 * lib/lightning.c: Remove the jit_regno_patch bitfield
1007 register fields before actual emit, as it is only really
1008 used before emit, otherwise, on special conditions it
1009 may consider live registers as dead during code emit.
1011 2015-02-15 Paulo Andrade <pcpa@gnu.org>
1013 * lib/jit_x86-cpu.c, lib/jit_x86-sse.c, lib/jit_x86-x87.c:
1014 Correct encoding of ldxr* stxr* in the x32 abi. If the
1015 displacement register is negative, it would generate
1016 a 64 bit instruction with a 32 bit unsigned displacement.
1018 * check/ranger.tst, check/ranger.ok: New files, implementing
1019 a test case for negative loads and stores. This is range.tst
1020 converted to use registers instead of immediate offsets.
1022 check/Makefile.am: Update for the new test case.
1024 2015-02-07 Paulo Andrade <pcpa@gnu.org>
1026 * lib/jit_size.c: Preventively use at least 144 bytes
1027 if JIT_INSTR_MAX is less than it. The logic is not
1028 guaranteed to be 100% precise, it is mostly heuristics
1029 to allocate a buffer with as close as possible size,
1030 but a wrong value may cause code generation to write
1031 past the end of the buffer.
1033 2015-02-03 Paulo Andrade <pcpa@gnu.org>
1035 * lib/lightning.c: Correct the reason the bug in
1036 simplify_stxi was not triggered before, it was due to
1037 incorrectly resetting the value->code field, what was
1038 causing it to never properly optimize:
1041 when Rb0 == Rb1, Rt0 == Rt1 and Im0 == Im1
1042 There was another possible issue, that has been also
1043 addressed in this commit, that would be the case of
1044 Rbn == Rtn, where no redundancy removal is possible.
1046 2015-02-03 Paulo Andrade <pcpa@gnu.org>
1048 * lib/lightning.c: Correct wrong check in simplify_stxi.
1049 The test was incorrectly comparing the target register
1050 and the displacement offset. This was a time bomb bug,
1051 that would trigger in code like:
1054 if Rb0 == Rb1 && Rt0 == Rt1 && Im0 == Rt1, that is,
1055 the wrong check was Im0 == Rt1, instead of the supposed
1056 Im0 == Imm1 (that was what the code mean't to do). It
1057 was removing the second stxi assuming it was redundantly
1058 generated; as that is not uncommon pattern on
1059 translators generating jit.
1061 2015-02-02 Paulo Andrade <pcpa@gnu.org>
1063 * configure.ac, include/lightning/jit_private.h,
1064 lib/jit_aarch64.c, lib/jit_alpha.c, lib/jit_arm.c,
1065 lib/jit_disasm.c, lib/jit_hppa.c, lib/jit_ia64.c,
1066 lib/jit_mips.c, lib/jit_ppc.c, lib/jit_print.c,
1067 lib/jit_s390.c, lib/jit_sparc.c, lib/jit_x86.c: Add a new
1068 --enable-devel-disassembler option, that should be used
1069 during development, or lightning debug. This option
1070 intermixes previous jit_print and jit_disassemble
1071 output, making it easier to visualize what lightning
1072 call was used, and what code was generated.
1074 2015-01-31 Paulo Andrade <pcpa@gnu.org>
1076 * lib/jit_arm-cpu.c, lib/jit_arm.c: Only limit to 24 bit
1077 displacement non conditional jump in the same jit_state_t.
1079 2015-01-19 Paulo Andrade <pcpa@gnu.org>
1081 * doc/body.texi: Reorder documentation, making jit_frame
1082 and jit_tramp the lightning response to the need of
1083 trampolines, continuations and tail call optimizations.
1084 A pseudo code example of a factorial function was added.
1085 Also added a section for description of the available
1088 * doc/fact.c: New file, implementing a simple example of
1089 a translation of a trivial, recursive, tail call optimization
1090 into lightning calls. This is the conversion to functional C
1091 code of the example in doc/body.texi.
1093 * doc/Makefile.am: Update for the next test case.
1095 2015-01-17 Paulo Andrade <pcpa@gnu.org>
1097 * include/lightning.h, lib/jit_aarch64.c,
1098 lib/jit_alpha.c, lib/jit_arm-vfp.c, lib/jit_arm.c,
1099 lib/jit_hppa.c, lib/jit_ia64.c, lib/jit_mips.c,
1100 lib/jit_ppc.c, lib/jit_s390.c, lib/jit_sparc.c,
1101 lib/jit_x86.c: Add the new jit_arg_register_p predicate.
1102 The predicate is expected to be used to know if an
1103 argument is in a register, what would need special
1104 handling if code that can overwrite non callee save
1105 registers is executed.
1107 * check/carg.c: New test case to check consistency and
1108 expected usage of jit_arg_register_p.
1110 * check/Makefile.am: Update for new test case.
1112 2015-01-17 Paulo Andrade <pcpa@gnu.org>
1114 * include/lightning/jit_aarch64.h,
1115 include/lightning/jit_alpha.h,
1116 include/lightning/jit_arm.h,
1117 include/lightning/jit_hppa.h,
1118 include/lightning/jit_mips.h,
1119 include/lightning/jit_ppc.h,
1120 include/lightning/jit_s390.h,
1121 include/lightning/jit_sparc.h,
1122 include/lightning/jit_x86.h,
1123 lib/jit_aarch64.c, lib/jit_alpha.c,
1124 lib/jit_arm.c, lib/jit_hppa.c,
1125 lib/jit_ia64.c, lib/jit_mips.c,
1126 lib/jit_ppc.c, lib/jit_s390.c,
1127 lib/jit_sparc.c, lib/jit_x86.c: Remove jit_arg_reg_p and
1128 jit_arg_f_reg_p from a public header, and define it only
1129 on port specific files where an integer offset is used
1130 to qualify an argument identifier. Exported code expects
1131 an opaque pointer (but of jit_node_t* type) to "qualify"
1132 an argument identifier.
1133 This patch, and the code review/simplification done during
1134 it also corrected some bugs:
1135 o Inconsistent jit_arg_d value of double argument after 3
1136 integer arguments in arm for jit_functions; tested, C
1137 functions were being properly called.
1138 o Inconsistent use of getarg_{f,d} and putarg*_{f,d} on
1139 s390 (32-bit) that happened to not have a proper test
1140 case, as it would only happen for jit functions, and
1141 tested, called C functions had proper arguments.
1142 o Corrected a "last minute" correction that did not go
1143 to the committed version, and would not compile on hppa,
1144 due to bad _jit_putargi_d prototype definition.
1146 2015-01-17 Paulo Andrade <pcpa@gnu.org>
1148 * doc/body.texi: Correct wrong/outdated information for
1149 hton*, pusharg* and ret*, and add missing documentation
1150 for rsb*, qmul*, qdvi* and putarg*.
1152 2015-01-15 Paulo Andrade <pcpa@gnu.org>
1154 * configure.ac, lib/jit_disasm.c: Rewrite workaround
1155 to apparent problem to initialize powerpc disassembler.
1157 2015-01-15 Paulo Andrade <pcpa@gnu.org>
1159 * include/lightning.h, lib/jit_aarch64.c,
1160 lib/jit_alpha.c, lib/jit_arm.c, lib/jit_hppa.c,
1161 lib/jit_ia64.c, lib/jit_mips.c, lib/jit_ppc.c,
1162 lib/jit_s390.c, lib/jit_sparc.c, lib/jit_x86.c:
1163 Implement jit_putarg*. It works as a mix of jit_getarg*
1164 and jit_pusharg*, in the way that the first argument is
1165 a register or immediate, and the second is a pointer
1166 returned by jit_arg*. The use of the interface is to change
1167 values of arguments to the current jit function.
1169 * check/put.ok, check/put.tst: New test cases exercising
1170 the new jit_putarg* interface.
1172 * check/Makefile.am, check/lightning.c: Update for the
1173 new test case and interface.
1175 2015-01-08 Paulo Andrade <pcpa@gnu.org>
1177 * include/lightning/jit_s390.h, lib/jit_s390-cpu.c,
1178 lib/jit_s390-fpu.c, lib/jit_s390-sz.c, lib/jit_s390.c:
1179 Renamed s390x* files to s390*.
1181 * check/float.tst, check/lightning.c, configure.ac,
1182 include/lightning.h, include/lightning/Makefile.am,
1183 lib/Makefile.am, lib/jit_s390.c, lib/jit_size.c,
1184 lib/lightning.c: Update for renamed files.
1186 2015-01-08 Paulo Andrade <pcpa@gnu.org>
1188 * include/lightning.h, include/lightning/jit_private.h,
1189 include/lightning/jit_s390x.h, lib/jit_disasm.c,
1190 lib/jit_s390x-cpu.c, lib/jit_s390x-fpu.c, lib/jit_s390x-sz.c,
1191 lib/jit_s390x.c, lib/jit_size.c, lib/lightning.c:
1192 Add support for generating jit for s390 32 bit. This change
1193 also removed %f15 from the list of temporaries fpr registers;
1194 it was not being used, but if were, it would corrupt the
1195 stack frame because the spill address would overwrite grp
1198 2014-12-26 Paulo Andrade <pcpa@gnu.org>
1200 * lib/jit_ppc-cpu.c, lib/jit_ppc.c: Correct some endianess issues
1201 on the powerpc le backend.
1203 2014-12-26 Paulo Andrade <pcpa@gnu.org>
1205 * lib/jit_ppc-cpu.c: Add mcrxr instruction emulation,
1206 as this instruction has been phased out, and should be
1207 implemented as a kernel trap.
1209 2014-12-26 Paulo Andrade <pcpa@gnu.org>
1211 * lib/jit_arm.c: Better check for need to flush constants
1212 before the pool being no longer reachable.
1214 2014-12-25 Paulo Andrade <pcpa@gnu.org>
1216 * include/lightning.h: Split jit_htonr in the new 3 interfaces
1217 jit_htonr_us, jit_htonr_ui and jit_htonr_ul, the later only
1218 available on 64 bit. The plain/untyped jit_htonr macro call
1219 maps to the wordsize one.
1220 * lib/jit_aarch64-cpu.c, lib/jit_aarch64-sz.c, lib/jit_aarch64.c,
1221 lib/jit_alpha-cpu.c, lib/jit_alpha-sz.c, lib/jit_alpha.c,
1222 lib/jit_arm-cpu.c, lib/jit_arm-sz.c, lib/jit_arm.c,

1225 lib/jit_mips-cpu.c, lib/jit_mips-sz.c, lib/jit_mips.c,
1226 lib/jit_ppc-cpu.c, lib/jit_ppc-sz.c, lib/jit_ppc.c,
1227 lib/jit_s390x-cpu.c, lib/jit_s390x-sz.c, lib/jit_s390x.c,
1228 lib/jit_sparc-cpu.c, lib/jit_sparc-sz.c, lib/jit_sparc.c,
1229 lib/jit_x86-cpu.c, lib/jit_x86-sz.c, lib/jit_x86.c:
1230 Update backends for the new jit_htonr*.
1231 * check/lightning.c, lib/jit_names.c, lib/lightning.c:
1232 Update for the new jit_htonr* interfaces.
1233 * check/Makefile.am: Update for new test cases.
1234 * check/hton.ok, check/hton.tst: New test cases.
1236 2014-12-24 Paulo Andrade <pcpa@gnu.org>
1238 * include/lightning/jit_private.h, include/lightning/jit_x86.h,
1239 lib/jit_disasm.c, lib/jit_x86-cpu.c, lib/jit_x86-sse.c,
1240 lib/jit_x86-sz.c, lib/jit_x86-x87.c, lib/jit_x86.c,
1241 size.c: Implement support for the x32 abi. Built and
1242 tested on Gentoo default/linux/amd64/13.0/x32 profile.
1244 2014-12-24 Paulo Andrade <pcpa@gnu.org>
1246 * lib/jit_names.c: Add missing rsbi_f and rsbi_d strings.
1248 2014-12-21 Paulo Andrade <pcpa@gnu.org>
1250 * lib/jit_arm.c: Call __clear_cache for every page.
1251 This should only be required for older boards or
1252 toolchain setup, but has been reported to be required
1253 for lightning at some point.
1255 2014-12-21 Paulo Andrade <pcpa@gnu.org>
1257 * lib/jit_arm.c: Correct check to guard overflow of index
1258 of constants from program counter.
1260 2014-11-24 Paulo Andrade <pcpa@gnu.org>
1262 * lib/lightning.c: Remove an optimization to calee save
1263 registers that may incorrectly remove a jit_movr under
1266 2014-11-20 Paulo Andrade <pcpa@gnu.org>
1268 * include/lightning/jit_ppc.h, lib/jit_ppc-cpu.c,
1269 lib/jit_ppc.c: Add initial powerpc le support.
1271 2014-11-20 Paulo Andrade <pcpa@gnu.org>
1273 * lib/jit_disasm.c: Change thumb or arm disassemble based on
1274 jit code before disassembly.
1276 * lib/jit_arm-cpu.c: Correct reversed arguments to LDRD and
1277 STRD instructions, and correct checking for support of those.
1279 * lib/jit_arm-swf.c: Correct wrong use of LDRD and STRD and
1280 only use those if the register is even.
1282 * check/check.arm.swf.sh, check/check.arm4.swf.sh: New files
1283 to test LDRD and STRD, as well as the alternate code path
1284 when those are not available, in the .arm4. test case.
1286 * check/Makefile.am: Update for the new test cases.
1288 2014-11-08 Paulo Andrade <pcpa@gnu.org>
1290 * include/lightning/jit_private.h, lib/jit_aarch64.c,
1291 lib/jit_alpha.c, lib/jit_arm.c, lib/jit_hppa.c,
1292 lib/jit_ia64.c, lib/jit_mips.c, lib/jit_ppc.c,
1293 lib/jit_s390x.c, lib/jit_sparc.c, lib/jit_x86.c:
1294 Implement a private jit_flush call, that flushes
1295 the cache, if applicable, aligning down to the
1296 previous and up to the next page boundary.
1298 2014-11-08 Paulo Andrade <pcpa@gnu.org>
1300 * check/ctramp.c: New file. It just repeats the test
1301 of tramp.tst, but using two jit_state_t, what should
1302 test possible issues with two contexts, and also validate
1303 jit_tramp works on backends with function descriptions.
1305 * check/Makefile.am: Update for new test case.
1307 2014-11-03 Paulo Andrade <pcpa@gnu.org>
1309 * include/lightning/jit_mips.h: Do not make the t9 register
1310 JIT_R11 (or JIT_R7 for n32 or n64 abi) available. Previously
1311 it cause problems if one expects it to not be changed in a
1312 function call. For example, calling a jit function, where it
1313 really does not need to be changed.
1315 2014-10-26 Paulo Andrade <pcpa@gnu.org>
1317 * lib/jit_aarch64.c, lib/jit_alpha.c, lib/jit_arm.c,
1318 lib/jit_hppa.c, lib/jit_ia64.c, lib/jit_mips.c, lib/jit_ppc.c,
1319 lib/jit_s390x.c, lib/jit_sparc.c, lib/jit_x86.c: Add an
1320 assertion to all code generation "drivers" to ensure
1321 _jitc->regarg is empty or in an expected state, after
1322 translation of a lightning instruction to native code.
1323 This change was a brute force test to find out other cases
1324 of a temporary not being release (like was happening with
1325 _bmsi and _bmci on x86), but no other case was found,
1326 after running make check, with assertions enabled, on all
1329 2014-10-26 Paulo Andrade <pcpa@gnu.org>
1331 * lib/jit_x86-cpu.c: Correct a register allocation leak in
1334 2014-10-25 Paulo Andrade <pcpa@gnu.org>
1336 * lib/jit_disasm.c: Do not cause an fatal error if init_jit
1337 fails in the jit_init_debug call.
1339 2014-10-24 Paulo Andrade <pcpa@gnu.org>
1341 * lib/jit_ia64.c, lib/jit_ppc.c: Correct handling of function
1342 descriptor when first prolog is a jit_tramp prolog. The
1343 test case was using the same jit_context_t, so was not
1344 triggering this condition.
1346 * lib/jit_ppc-cpu.c: Properly handle jump displacements that
1347 do not fit on 24 powerpc. This required changing from previous
1348 "mtlr reg, blr" to "mtctr reg, bctr" to properly handle
1349 the logic to "hide" function descriptors, but that would
1350 also be required as the proper jit_jmpr when/if implementing
1351 optimizations to leaf functions (was working with blr because
1352 it is saved/reloaded in prolog/epilog).
1354 2014-10-21 Paulo Andrade <pcpa@gnu.org>
1356 * include/lightning.h, lib/lightning.c: Add three predicates
1357 to query information about labels. jit_forward_p(label)
1358 will return non zero if the label is "forward", that is
1359 need a call to jit_link(label), jit_indirect_p(label)
1360 that returns non zero if the label was created with the
1361 jit_indirect() call, and jit_target_p(label) that will
1362 return non zero if there is at least one jump patched
1363 to land at that label.
1365 2014-10-18 Paulo Andrade <pcpa@gnu.org>
1367 * check/range.ok, check/range.tst: New test case designed
1368 to catch incorrect code generation, usually due to incorrect
1369 test of immediate size. The test checks a large amount of
1370 encodings in "power of two" boundaries. This test exorcises
1371 a significant amount of code paths that was previously not
1374 * check/Makefile.am: Add range test to make check target.
1376 * lib/jit_aarch64-cpu.c: Correct wrong address calculation
1377 for stxi_c, stxi_s, stxi_i and stxi_l when the offset is
1380 * lib/jit_mips-fpu.c: Correct wrong size test to check if
1381 an immediate can be encoded in a float or double store.
1383 * lib/jit_s390x-cpu.c: Correct inverted encoding to stxi_s
1384 when the offset cannot be encoded, and fallbacks to an
1385 alternate encoding in 2 instructions.
1387 2014-10-17 Paulo Andrade <pcpa@gnu.org>
1389 * check/alu_rsb.ok, check/alu_rsb.tst: New files implementing
1392 * check/Makefile.am, check/lightning.c, include/lightning.h,
1393 lib/jit_aarch64-cpu.c, lib/jit_aarch64-fpu.c, lib/jit_aarch64-sz.c,

1407 lib/jit_x86.c, lib/lightning.c: Implement jit_rsb*. This
1408 was a missing lightning 1.x interface, that on most
1409 backends is synthesized, but on a few backends (hppa and ia64),
1410 it can generate better code as on those there is, or the
1411 only instruction with an immediate is in "rsb" format
1414 2014-10-17 Paulo Andrade <pcpa@gnu.org>
1416 * lib/jit_names.c: New file with single definition of string
1417 representation of lightning IR codes.
1419 * size.c: Modified to append the code name in a C comment
1420 after the maximum instruction size.
1422 * lib/jit_print.c: Minor change to not duplicate jit_names.c
1425 * lib/jit_aarch64-sz.c, lib/jit_alpha-sz.c, lib/jit_arm-sz.c,
1426 lib/jit_hppa-sz.c, lib/jit_ia64-sz.c, lib/jit_mips-sz.c,
1427 lib/jit_ppc-sz.c, lib/jit_s390x-sz.c, lib/jit_sparc-sz.c,
1428 lib/jit_x86-sz.c: Rewritten to add string representation of
1429 IR codes in a C comment.
1431 2014-10-14 Paulo Andrade <pcpa@gnu.org>
1433 * lib/jit_aarch64-cpu.c, lib/jit_alpha-cpu.c, lib/jit_arm-cpu.c,
1434 lib/jit_hppa-cpu.c, lib/jit_mips-cpu.c, lib/jit_ppc-cpu.c,
1435 lib/jit_sparc-cpu.c: Implement or correct the internal
1436 nop(count) call that receives an argument that tells the
1437 modulo bytes to align the code for the next instruction.
1439 * include/lightning.h, lib/lightning.c, lib/jit_aarch64.c,
1440 lib/jit_alpha.c, lib/jit_arm.c, lib/jit_hppa.c, lib/jit_ia64.c,
1441 lib/jit_mips.c, lib/jit_ppc.c, lib/jit_s390x.c, lib/jit_sparc.c,
1442 lib/jit_x86.c: Implement the new jit_align() call that receive
1443 an argument, that tells the modulo, in bytes, to align the
1444 next instruction. In most backends the only value that makes
1445 a difference is a value that matches sizeof(void*), as all
1446 other values usually are already automatically aligned in
1447 labels, but not guaranteed to be aligned at word size bytes.
1449 * check/align.ok, check/align.tst: New files, implementing
1450 a simple test for the new jit_align() interface.
1452 * check/Makefile.am, check/lightning.c, lib/jit_aarch64-sz.c,
1453 lib/jit_alpha-sz.c, lib/jit_arm-sz.c, lib/jit_hppa-sz.c,

1455 lib/jit_print.c, lib/jit_s390x-sz.c, lib/jit_sparc-sz.c,
1456 lib/jit_x86-sz.c: Update for the new jit_code_align code and
1457 the jit_align() interface.
1459 2014-10-13 Paulo Andrade <pcpa@gnu.org>
1461 * include/lightning.h, lib/jit_size.c, size.c: Use a
1462 symbolic value for the last IR code.
1464 2014-10-12 Paulo Andrade <pcpa@gnu.org>
1466 * include/lightning.h, include/lightning/jit_private.h,
1467 lib/jit_aarch64-cpu.c, lib/jit_alpha-cpu.c, lib/jit_arm-cpu.c,
1468 lib/jit_hppa-cpu.c, lib/jit_ia64-cpu.c, lib/jit_mips-cpu.c,
1469 lib/jit_ppc-cpu.c, lib/jit_s390x-cpu.c, lib/jit_sparc-cpu.c,
1470 lib/jit_x86-cpu.c, lib/lightning.c: Implement the new
1471 jit_frame and jit_tramp interfaces, that allow writing
1472 trampoline like calls, where a single dispatcher jit buffer
1473 is written, and later other jit buffers are created, with
1474 the same stack frame layout as the dispatcher. This is the
1475 logic that GNU Smalltalk used in lightning 1.x, and is required
1476 to make a sane port for lighting 2.x.
1478 * jit_ia64-cpu.c: Implement support for jit_frame and jit_tramp,
1479 and also correct wrong encoding for B4 instructions, that
1480 implement jmpr, as well as correct reverse logic in _jmpr,
1481 that was moving the branch register to the jump register,
1483 Also, if a stack frame is to be assumed, always assume it may
1484 call a function with up to 8 arguments, regardless of the
1485 hint frame argument.
1487 * lib/jit_arm.c: Add a new must_align_p() interface to ensure
1488 function prologs are always aligned. This condition was
1489 previously always true, somewhat by accident, but with
1490 jit_tramp it is not guaranteed.
1492 * jit_ia64-cpu.c: lib/jit_ppc.c: Add minor special handling
1493 required to implement jit_tramp, where a function descriptor
1494 should not be added before a prolog, as jit_tramp means omit
1497 * check/lightning.c: Update test driver for the new interfaces.
1499 * check/Makefile.am, check/tramp.tst, check/tramp.ok: Add
1500 a simple test and example of the jit_frame and jit_tramp
1501 usage implementing a simple Fibonacci function using a
1502 simulation of an interpreter stack and how it would handle
1503 state in language specific variables.
1505 * doc/body.texi: Add documentation for jit_frame and
1508 2014-09-29 Paulo Andrade <pcpa@gnu.org>
1510 * lib/jit_aarch64.c, lib/jit_alpha.c, lib/jit_arm.c,
1511 lib/jit_hppa.c, lib/jit_ia64.c, lib/jit_mips.c,
1512 lib/jit_ppc.c, lib/jit_s390x.c, lib/jit_sparc.c,
1513 lib/jit_x86.c, lib/lightning.c: Allow jit_jmpi on a
1514 target that is not a node. This may lead to hard to
1515 debug code generation, but is a required feature for
1516 certain generators, like the ones that used lightning
1517 1.2x. Note that previously, but not really well
1518 documented, it was instructed to use:
1519 jit_movi(rn, addr); jit_jmpr(rn);
1521 jit_patch_abs(jit_jmpi(), addr);
1524 2014-09-24 Paulo Andrade <pcpa@gnu.org>
1526 * lib/jit_x86-sz.c: Generate information about instruction
1527 lengths for more precise calculation of buffer size on
1528 Windows x64. This change is specially important because
1529 the maximum instruction length is larger than other
1530 systems, what could cause an out of bounds write on
1531 special conditions without this update.
1533 2014-09-24 Paulo Andrade <pcpa@gnu.org>
1535 * check/lightning.c: Add workaround to conflicting global
1536 optind variable in cygwin binutils that have an internal
1537 getopt* implementation.
1539 * lib/jit_x86-cpu.c: Add a simple define ffsl ffs if building
1540 for 32 bit and there is no ffsl function.
1542 2014-09-24 Paulo Andrade <pcpa@gnu.org>
1544 * check/lightning.c: Add a hopefully temporary kludge to not use
1545 sprintf and sscanf returned by dlsym. This is required to pass
1548 * include/lightning/jit_private.h: Use symbolic name for first
1549 integer register argument, as this is different in sysv and
1552 * include/lightning/jit_x86.h: Add conditionals and definitions
1553 for Windows x64 (under __CYGWIN__ preprocessor conditional).
1555 * lib/jit_x86-cpu.c: Correct one instruction encoding bug, that
1556 was working by accident. Only use rax to rdx for some byte
1557 operations to work on compatibility mode (that is, to generate
1558 the proper encoding, instead of actually generating encoding
1559 for high byte registers, e.g. %bh).
1560 Add proper prolog and epilog for windows x64.
1562 * lib/jit_x86-sse.c: Correct a swapped rex prefix for float
1565 * lib/jit_x86.c: Adjust to support Windows x64 abi.
1567 * check/check.x87.nodata.sh: New file, previously used but that
1570 2014-09-07 Paulo Andrade <pcpa@gnu.org>
1572 * lib/lightning.c: Mark all registers advertised as live, as
1573 per jit_callee_save_p as live whenever reaching a jump that
1574 cannot be tracked. This is a rethink of the previous commit,
1575 and is a better approach, otherwise there would not be much
1576 sense on relying on jit_callee_save_p if it could not be
1579 * check/jmpr.tst, check/jmpr.ok: New files implementing a very
1580 simple test case, that would actually cause an assertion on
1581 code before the change to only mark as live when reaching a
1582 jump that could not tracked, the actually advertised as callee
1585 check/Makefile.am: Update for new jmpr test case.
1587 2014-09-01 Paulo Andrade <pcpa@gnu.org>
1589 * lib/lightning.c: Do not mark all registers in unknown state
1590 as live on jit_jmpr, or jit_jmpi to an absolute address. Instead,
1591 treat it as a function call, and only consider JIT_Vn registers
1594 2014-08-29 Paulo Andrade <pcpa@gnu.org>
1596 * doc/body.texi: Add a proper info menu entry for
1599 * doc/version.texi: Regenerate.
1601 2014-08-16 Paulo Andrade <pcpa@gnu.org>
1603 * lib/jit_aarch64-cpu.c, lib/jit_aarch64-fpu.c,

1605 lib/jit_hppa-cpu.c, lib/jit_hppa-fpu.c,

1611 lib/jit_x86-cpu.c, lib/jit_x86-sse.c,
1612 lib/jit_x86-x87.c: Review generation of all branch
1613 instructions and always adds the jit_class_nospill
1614 bitfield for temporary registers that cannot be spilled
1615 because the reload would be after a conditional jump; the
1616 patch only adds an extra assertion. These conditions do
1617 not happen on documented lightning usage, but can happen
1618 if one uses the not exported jit_get_reg and jit_unget_reg
1619 calls and cause enough register starvation.
1621 2014-08-16 Paulo Andrade <pcpa@gnu.org>
1623 * lib/jit_alpha.c: Correct wrong bitmask of most argument
1624 float register arguments, that were being set as callee
1625 save instead of argument registers class.
1627 2014-08-16 Paulo Andrade <pcpa@gnu.org>
1629 * lib/jit_arm-sz.c: Regenerate table of known maximum
1630 instruction sizes for the software float fallback,
1631 that implements "virtual" float registers in the stack
1632 and operations as calls to libgcc.
1634 * size.c: Correct typo in the generated jit_arm-sz.c file.
1636 2014-08-10 Paulo Andrade <pcpa@gnu.org>
1638 * include/lightning/jit_alpha.h, lib/jit_alpha-cpu.c,
1639 lib/jit_alpha-fpu.c, lib/jit_alpha-sz.c, lib/jit_alpha.c:
1640 New files implementing a lightning Alpha port. Thanks
1641 to Trent Nelson and snakebit.net staff for providing access
1644 * check/float.tst, check/lightning.c, configure.ac,
1645 include/lightning.h, include/lightning/Makefile.am,
1646 include/lightning/jit_private.h, lib/Makefile.am,
1647 lib/jit_disasm.c, lib/jit_size.c, lib/lightning.c:
1648 Minor changes to adapt for the new Alpha port.
1650 2014-08-10 Paulo Andrade <pcpa@gnu.org>
1652 * lib/lightning.c: Always mark JIT_RET and JIT_FRET as
1653 live in a function epilog. This is required because
1654 on some ports a complex sequence, allocating one or more
1655 registers, may be required to jump from a ret* to the
1656 epilog, and the lightning api does not have annotations
1657 to know if a function returns a value, or the type of
1660 2014-08-10 Paulo Andrade <pcpa@gnu.org>
1662 * lib/lightning.c: Change the correct live bitmask of
1663 return registers after a function call in jit_update.
1665 2014-08-10 Paulo Andrade <pcpa@gnu.org>
1667 * lib/lightning.c: Change assertions to have an int
1668 result and correct a bad bit mask assertion.
1670 2014-08-10 Paulo Andrade <pcpa@gnu.org>
1672 * lib/jit_aarch64.c: Correct bad setup for assertion
1673 of consistency before a patch.
1675 2014-08-10 Paulo Andrade <pcpa@gnu.org>
1677 * lib/jit_mips-cpu.c: Correct typo in the jit_bmsr
1678 implementation that was using the wrong test result
1681 2014-07-28 Paulo Andrade <pcpa@gnu.org>
1683 * lib/jit_memory.c: Do not call free on NULL pointers.
1685 * include/lightning/jit_private.h, lib/jit_note.c,
1686 lib/lightning.c: Add a wrapper to memcpy and memmove
1687 to not actually call those functions with a zero size
1688 argument, and likely also a null src or dst.
1690 2014-07-27 Paulo Andrade <pcpa@gnu.org>
1692 * include/lightning/jit_private.h, lib/jit_disasm.c,
1693 lib/lightning.c: Remove the global jit_progname variable.
1694 It was being only used in jit_init_debug, that is called
1695 from init_jit, so, just pass an argument.
1697 2014-07-27 Paulo Andrade <pcpa@gnu.org>
1699 * doc/body.texi: Add note that jit_set_memory_functions
1700 should be called before init_jit, because init_jit
1701 itself may call the memory wrappers.
1703 2014-04-22 Paulo Andrade <pcpa@gnu.org>
1705 * lib/jit_arm.c: Do not get confused with default settings
1706 if /proc is not mounted on Linux specific code path.
1708 2014-04-09 Paulo Andrade <pcpa@gnu.org>
1710 * include/lightning/jit_aarch64.h, include/lightning/jit_arm.h,
1711 include/lightning/jit_hppa.h, include/lightning/jit_ia64.h,
1712 include/lightning/jit_mips.h, include/lightning/jit_ppc.h,
1713 include/lightning/jit_private.h, include/lightning/jit_s390x.h,
1714 include/lightning/jit_sparc.h, include/lightning/jit_x86.h:
1715 Do not add jit_regset_t, JIT_RA0, and JIT_FA0 to the installed
1716 header file. These types and definitions are supposed to be
1717 only used internally.
1719 2014-04-05 Paulo Andrade <pcpa@gnu.org>
1721 * lib/jit_arm-cpu.c: Only adjust stack pointer in prolog if
1722 need stack space, that is, do not emit a nop instruction
1723 subtracting zero from the stack pointer.
1725 2014-04-04 Paulo Andrade <pcpa@gnu.org>
1727 * lib/jit_disasm.c: Correct a crash in the doc/printf example
1728 on arm due to releasing the data_info information in
1729 jit_clear_state. This is a special case for arm only, and
1730 actually, only armv5 or older uses the data_info buffer,
1731 or when forcing arm instruction set mode besides thumb
1734 2014-12-03 Paulo Andrade <pcpa@gnu.org>
1736 * doc/body.texi: Write detailed description and examples for
1737 jit_get_memory_functions, jit_set_memory_functions,
1738 jit_get_code, jit_set_code, jit_get_data and jit_set_data.
1740 2014-12-03 Paulo Andrade <pcpa@gnu.org>
1742 * include/lightning.h, include/lightning/jit_private.h,
1743 lib/lightning.c: Implement the new jit_set_data() interface,
1744 and the new jit_get_data() helper. Like jit_set_code(),
1745 jit_realize() should be called before jit_set_data().
1746 The most common usage should be jit_set_data(JIT_DISABLE_DATA
1747 | JIT_DISABLE_NOTE), to force synthesize any float/double
1748 constant in the stack and not generate any debug information.
1750 * lib/jit_note.c: Minor change to debug note generation as
1751 now it uses an alternate temporary data buffer during constants
1752 and debug generation to accommodate the possibility of the user
1753 setting an alternate data buffer.
1755 * lib/jit_hppa-fpu.c, lib/jit_s390x.c, lib/jit_s390x-cpu.c,
1756 lib/jit_s390x-fpu.c, lib/jit_sparc.c, lib/jit_sparc-fpu.c,
1757 lib/jit_x86-sse.c, lib/jit_x86-x87.c: Implement jit_set_data.
1759 * lib/jit_hppa-sz.c, lib/jit_sparc-sz.c, lib/jit_x86-sz.c,
1760 lib/jit_s390x-sz.c: Update for several instructions that now
1761 have a different maximum length due to jit_set_data.
1763 * lib/jit_mips-fpu.c: Implement jit_set_data, but missing
1764 validation on n32 and n64 abis (and/or big endian).
1766 * lib/jit_mips-sz.c: Update for changes in o32.
1768 * lib/jit_ppc-fpu.c: Implement jit_set_data, but missing
1769 validation on Darwin PPC.
1771 * lib/jit_ppc-sz.c: Update for changes in powerpc 32 and
1774 * lib/jit_ia64-fpu.c: Implement untested jit_set_data.
1776 * TODO: Add note to list ports that were not tested for the
1777 new jit_set_data() feature, due to no longer having access
1780 * check/nodata.c: New file implementing a simple test exercising
1781 several different conditions created by jit_set_data().
1783 * check/check.nodata.sh: New file implementing a wrapper
1784 over the existing *.tst files, that runs all tests without
1785 using a data buffer for constants; only meaningful (and
1786 enabled) on architectures that used to store float/double
1787 constants on a read only data buffer.
1789 * configure.ac, check/Makefile.am: Update for the new test
1792 * check/lightning.c: Implement the new "-d" option that
1793 sets an internal flag to call jit_set_data() disable
1794 constants and debug, that is, using only a pure code
1797 2014-11-03 Paulo Andrade <pcpa@gnu.org>
1799 * include/lightning.h, include/lightning/jit_private.h,
1800 lib/lightning.c: Implement the new jit_set_code() interface,
1801 that allows instructing lightning to use an alternate code
1802 buffer. The new jit_realize() function should be called
1803 before jit_set_code(), and usually call jit_get_code()
1804 to query the amount of bytes expected to be required for
1807 * lib/jit_size.c: Minor update to have less chances of
1808 miscalculating the code buffer by starting the counter
1809 with the size of the longest instruction instead of zero,
1810 as code emit fails if at any moment less than the longest
1811 instruction bytes are available.
1813 * check/setcode.c: New file implementing some basic tests
1814 of the new jit_set_code() interface.
1816 * check/Makefile.am: Update for newer test case.
1818 2014-06-03 Paulo Andrade <pcpa@gnu.org>
1820 * include/lightning.h, lib/lightning.c: Add the new
1821 jit_indirect() call, that returns a special label node,
1822 and tells lightning that the label may be the target of
1825 * doc/body.texi: Document the new jit_indirect() call, and
1826 add examples of different ways to create labels and branches.
1828 2014-23-02 Paulo Andrade <pcpa@gnu.org>
1830 * lib/jit_x86.c: Rewrite previous patch to inline save/restore
1831 because clobbering %ebx in x86 is treated as an error
1832 (jit_x86.c:239:5: error: PIC register clobbered by 'ebx' in 'asm').
1834 2014-19-02 Paulo Andrade <pcpa@gnu.org>
1836 * lib/jit_x86.c: Rewrite incorrect inline assembly that could
1837 truncate a variable in a callee save register. Now it simply
1838 tells gcc that the register is clobbered, instead of using a
1839 *32 bit* swap with a temporary variable. The problem only
1840 happens when compiling with optimization.
1842 2014-19-02 Paulo Andrade <pcpa@gnu.org>
1844 * include/lightning/jit_aarch64.h, include/lightning/jit_arm.h,
1845 include/lightning/jit_hppa.h, include/lightning/jit_ia64.h,
1846 include/lightning/jit_mips.h, include/lightning/jit_ppc.h,
1847 include/lightning/jit_s390x.h, include/lightning/jit_sparc.h,
1848 include/lightning/jit_x86.h: Change jit_regset_t to an
1849 unsigned type, to allow safe right shift.
1851 * lib/lightning.c: Rewrite jit_regset_scan1 to allow easier
1852 compiler optimization.
1854 2013-12-03 Paulo Andrade <pcpa@gnu.org>
1856 * lib/jit_x86-x87.c: Correct wrong optimization when
1857 loading the log(2) constant.
1859 2013-12-03 Paulo Andrade <pcpa@gnu.org>
1861 * lib/jit_x86-cpu.c: Use the emms instruction before
1862 calling any function. This is particularly important
1863 when using c99 complex functions as it can easily
1864 overflow the x87 stack due to the way lightning uses
1865 the x87 stack as a flat register file.
1867 2013-12-02 Paulo Andrade <pcpa@gnu.org>
1869 * lib/jit_x86-x87.c: Correct wrong code generation due
1870 to comparing the base and not the value register with
1873 2013-12-02 Paulo Andrade <pcpa@gnu.org>
1875 * lib/jit_x86-x87.c, lib/jit_x86.c: Use 8 bytes aligned
1876 stack offset for float/double x87 to/from sse move.
1878 2013-11-27 Paulo Andrade <pcpa@gnu.org>
1880 * configure.ac, lib/jit_arm-swf.c, lib/jit_arm.c: Add
1881 changes that should at least allow building lightning
1884 2013-10-08 Paulo Andrade <pcpa@gnu.org>
1886 * lib/jit_ppc-cpu.c: Correct wrong shortcut for ldxi_l with
1887 a zero offset, that was calling ldr_i instead of ldr_l.
1889 2013-10-08 Paulo Andrade <pcpa@gnu.org>
1891 * include/lightning/jit_arm.h, lib/jit_arm-cpu.c: Do not use
1892 by default load/store instructions that map to ldrt/strt.
1893 There is already the long displacement version for positive
1894 offsets, and when using a (shorter) negative offset it does
1895 not map to ldrt/strt. At least on qemu strt may cause
1896 reproducible, but unexpected SIGILL.
1898 2013-10-08 Paulo Andrade <pcpa@gnu.org>
1900 * lib/jit_arm-vfp.c: Correct wrong load/store offset
1901 calculation when the displacement is constant but too
1902 large to use an instruction with an immediate offset.
1904 2013-10-07 Paulo Andrade <pcpa@gnu.org>
1906 * check/self.c: Extend tests to validate jit_callee_save_p
1907 does not cause an assertion on valid arguments, and test
1908 extra registers defined on some backends.
1910 * configure.ac: Do not ignore environment CFLAGS when
1911 checking if need to test runtime configurable options,
1912 like use x87 when sse2 is available, arm instruction set
1913 instead of thumb, etc.
1915 * include/lightning/jit_arm.h: Correct wrong jit_f macro
1918 * include/lightning/jit_ia64.h, include/lightning/jit_ppc.h:
1919 Correct wrong jit_r macro definition.
1921 * lib/jit_x86-x87.c, lib/jit_x86.c: Actually use the
1922 reserved stack space for integer to/from float conversion.
1923 The stack space was also changed to ensure it is 8 bytes
1924 aligned. Also, for Solaris x86 in 32 bit mode, an alternate
1925 truncr_d was implemented because for some reason it is
1926 failing with SIGILL if using the "fisttpl" instructions,
1927 that must be available on p6 or newer, but for the sake of
1928 making all tests pass, implement a 486 or newer sequence
1929 if "sun" is defined.
1931 2013-10-03 Paulo Andrade <pcpa@gnu.org>
1933 * include/lightning/jit_mips.h, lib/jit_mips-cpu.c,
1934 lib/jit_mips-sz.c, lib/jit_mips.c, size: Build and
1935 pass all test cases on Irix big endian mips using
1938 2013-10-02 Paulo Andrade <pcpa@gnu.org>
1940 * include/lightning/jit_mips.h: Add proper mips abi detection.
1942 2013-09-30 Paulo Andrade <pcpa@gnu.org>
1944 * lib/jit_print.c: Do not crash if calling jit_print from
1945 gdb before actually emitting code.
1947 * lib/lightning.c: Correct misplaced check for already
1948 visited blocks on conditional branches, what was preventing
1949 proper merge live bit masks of forward blocks.
1951 2013-09-30 Paulo Andrade <pcpa@gnu.org>
1953 * lib/jit_x86-cpu.c: Correct not properly tested case of using
1954 %r12 as index register, what was causing an invalid assertion.
1955 %r12 is mapped to the "extra" JIT_R3 register, and test cases
1956 only test "standard" lightning registers.
1958 2013-09-28 Paulo Andrade <pcpa@gnu.org>
1960 * lib/jit_ia64.c: Minor change to force collecting the maximum
1961 instruction length in the --enable-devel-get-jit-size build
1962 mode. The actual generated file did not change because the
1963 sampling was large enough that it had already collected proper
1964 information in the previously slightly buggy code (not forcing
1965 a sync of the instructions that could be combined).
1967 2013-09-27 Paulo Andrade <pcpa@gnu.org>
1969 * lib/jit_arm.c: Correct build when disassembler is
1972 2013-09-25 Paulo Andrade <pcpa@gnu.org>
1974 * lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c: Correct some
1975 off by one range checks (that were only accepting values
1976 one less than the maximum allowed) and an invalid test
1977 condition check that was forcing it to always use
1978 indirect jumps even when reachable with an immediate
1981 2013-09-24 Paulo Andrade <pcpa@gnu.org>
1983 * lib/jit_aarch64-sz.c, lib/jit_arm-sz.c, lib/jit_hppa-sz.c,
1984 lib/jit_ia64-sz.c, lib/jit_mips-sz.c, lib/jit_ppc-sz.c,
1985 lib/jit_s390x-sz.c, lib/jit_size.c, lib/jit_sparc-sz.c,
1986 lib/jit_x86-sz.c: New files implementing static tables
1987 with longest known instructions length generated to match
1988 a lightning instruction. These tables should make it easier
1989 to make it very unlikely to ever miscalculate, or by too
1990 much, the size of a code buffer.
1992 * lib/jit_size.c: New file that aids to either collect
1993 jit code size information, or use the information depending
1996 * size.c: New helper file that parses input for, and create
1997 an initial jit_$arch-sz.c file, that needs some minor edit
1998 for arches with multiple configurations.
2000 * configure.ac, Makefile.am: Add the new, devel mode only
2001 --enable-devel-get-jit-size configure option, that sets
2002 compile time flags to collect jit code size information,
2003 that will be used as input for the "noinst size program".
2005 * lib/jit_aarch64.c, lib/jit_arm.c, lib/jit_disasm.c,
2006 lib/jit_hppa.c, lib/jit_ia64.c, lib/jit_memory.c,
2007 lib/jit_mips.c, lib/jit_ppc.c, lib/jit_s390x.c,
2008 lib/jit_sparc.c, lib/jit_x86.c, lib/lightning.c: Minor
2009 changes for the --enable-devel-get-jit-size build mode,
2010 as well as the "production build mode" with jit code
2013 2013-09-14 Paulo Andrade <pcpa@gnu.org>
2015 * include/lightning.h, lib/lightning.c: Add the new
2016 jit_pointer_p interface, that returns a boolean value
2017 telling if the pointer argument is inside the jit
2018 code buffer. This is useful to avoid the need to add
2019 extra labels and calls to jit_address to figure bounds
2020 of code buffer, and still keep internal data private.
2022 2013-09-13 Paulo Andrade <pcpa@gnu.org>
2024 * include/lightning.h, include/lightning/jit_private.h,
2025 lib/jit_note.c: Change the code argument of jit_get_note
2026 to a jit_pointer_t and make jit_get_note a public interface.
2027 It was intended so since start, as a way to map an offset
2028 in the code to a function name, file name and line number
2031 2013-09-11 Paulo Andrade <pcpa@gnu.org>
2033 * doc/body.texi: Correct reversed arguments in example of
2034 usage in a (possibly) multi threaded, multiple jit_state_t
2037 * include/lightning/jit_arm.h, include/lightning/jit_private.h,
2038 lib/jit_arm-cpu.c, lib/jit_arm.c: Make a previously, non
2039 documented, global state private to the related jit_state_t
2042 2013-09-10 Paulo Andrade <pcpa@gnu.org>
2044 * check/self.c, check/self.ok: New files implementing simple
2045 consistency check assertions. At first validating some macros
2046 that use values from different sources agree.
2048 * check/Makefile.am: Update for the new test case.
2050 * include/lightning.h, lib/lightning.c: Add the new
2051 jit_callee_save_p() call, that is intended to be used when
2052 writing complex code using lightning, so that one does not
2053 need to verify what backend is being used, or have access to
2054 private data, to query if a register is callee save or not;
2055 on several backends the scratch registers are actually callee
2058 * include/lightning/jit_aarch64.h, include/lightning/jit_arm.h,
2059 include/lightning/jit_hppa.h, include/lightning/jit_mips.h,
2060 include/lightning/jit_ppc.h, include/lightning/jit_sparc.h,
2061 include/lightning/jit_x86.h: Add an explicit definition for
2062 JIT_R3-JIT_Rn, JIT_V3-JIT_Vn and JIT_F6-JIT_Fn when applicable.
2063 This allows one to write code based on "#if defined(JIT_XN)"
2064 and therefore, not need to check what is the current backend
2065 or have access to private data structures. This is particularly
2066 useful when writing virtual machines with several specialized,
2069 * lib/jit_ia64.c: Properly flag the callee save general
2070 purpose registers as such, so that jit_callee_save_p() works
2073 2013-09-10 Paulo Andrade <pcpa@gnu.org>
2075 * check/lightning.c, configure.ac: Conditionally use the
2076 code written to workaround a bug in the Hercules emulator,
2077 as isnan and isinf are not available at least on HP-UX ia64.
2079 2013-09-10 Paulo Andrade <pcpa@gnu.org>
2081 * lib/jit_s390x-cpu.c: Spill/reload correct callee save
2084 2013-09-10 Paulo Andrade <pcpa@gnu.org>
2086 * lib/jit_hppa-cpu.c: Correct code to call a function stored
2087 in a register or a patched function address.
2089 2013-09-10 Paulo Andrade <pcpa@gnu.org>
2091 * lib/jit_ia64-cpu.c: Correct incorrect logic when restoring
2092 the value of the "r2" callee save register.
2094 2013-08-29 Paulo Andrade <pcpa@gnu.org>
2096 * lib/jit_arm-cpu.c, lib/jit_arm.c: Correct wrong test and update
2097 of the thumb offset information, when checking if needing to
2098 patch a jump from arm to thumb mode. The problem would happen when
2099 remapping the code buffer, and the new address being lower than
2102 2013-08-26 Paulo Andrade <pcpa@gnu.org>
2104 * configure.ac: Extend FreeBSD test to also handle NetBSD.
2106 * lib/jit_x86-cpu.c: Correct wrongly defined offset type of
2107 ldxi_ui. Problem detected when building on NetBSD.
2109 * lib/lightning.c: Adjust code to handle NetBSD mremap,
2110 where arguments do not match Linux mremap.
2112 2013-08-26 Paulo Andrade <pcpa@gnu.org>
2114 * lib/jit_ppc.c: Correct C sequence point problem miscalculating
2115 the actual function address in a function descriptor. Problem
2116 happens with gcc 4.8.1 at least.
2118 2013-08-11 Paulo Andrade <pcpa@gnu.org>
2120 * lib/jit_s390x-cpu.c: Correct code checking if immediate
2121 fits instruction, but using the negated value.
2123 2013-07-28 Paulo Andrade <pcpa@gnu.org>
2125 * include/lightning/jit_s390x.h, lib/jit_s390x-cpu.c,
2126 lib/jit_s390x-fpu.c, lib/jit_s390x.c: New files
2127 implementing the new s390x port.
2129 * configure.ac, include/lightning.h,
2130 include/lightning/Makefile.am,
2131 include/lightning/jit_private.h,
2132 lib/Makefile.am, lib/jit_disasm.c, lib/lightning.c:
2133 Minor adaptation for the new s390x backend.
2135 * check/float.tst: Update for the s390x result of
2136 truncating +Inf to integer.
2138 * check/qalu_mul.tst: Add extra test cases to better test
2139 high word of signed multiplication as the result is
2140 adjust from unsigned multiplication on s390x.
2142 2013-07-28 Paulo Andrade <pcpa@gnu.org>
2144 * check/lightning.c: Do not assume casting a double NaN or
2145 Inf to float will produce the expected float NaN or Inf.
2146 This is not true at least under s390x.
2148 2013-07-28 Paulo Andrade <pcpa@gnu.org>
2150 * check/check.arm.sh, check/check.sh, check/check.swf.sh,
2151 check/check.x87.sh: Properly check test programs output,
2152 not just rely on the test program self testing the results
2155 2013-07-28 Paulo Andrade <pcpa@gnu.org>
2157 * lib/jit_aarch64.c: Remove unused macros left from cut&paste
2160 2013-07-16 Paulo Andrade <pcpa@gnu.org>
2162 * include/lightning/jit_aarch64.h, lib/jit_aarch64-cpu.c,
2163 lib/jit_aarch64-fpu.c, lib/jit_aarch64.c: New files
2164 implementing the new aarch64 port, as a new architecture,
2165 not as an expansion of the existing armv[4-7] port.
2167 * check/lightning.c: Add aarch64 support and a small
2168 change to recognize character constants as immediate
2171 * check/float.tst: Add aarch64 preprocessor conditionals
2172 to select proper expected value when converting [+-]Inf
2175 * include/lightning/jit_arm.h, lib/jit_arm.c: Minor changes
2176 to better match the new aarch64 files.
2178 * configure.ac, include/lightning.h,
2179 include/lightning/Makefile.am, include/lightning/jit_private.h,
2180 lib/Makefile.am, lib/lightning.c: Minor adjustments
2181 for the aarch64 port.
2183 2013-07-08 Paulo Andrade <pcpa@gnu.org>
2185 * NEWS, THANKS, configure.ac, doc/version.texi: Update for
2186 the 1.99a second alpha release.
2188 2013-06-25 Paulo Andrade <pcpa@gnu.org>
2190 * lib/jit_mips.c: Correct cut&paste error that caused wrong
2191 stack offset calculation for double arguments in stack in
2193 Correct typo in the __LITTLE_ENDIAN macro name, that came
2194 from cut&paste error in the original typo in lib/jit_ppc.c.
2196 * lib/jit_ia64.c, lib/jit_ppc.c: Correct typo in the
2197 __LITTLE_ENDIAN macro name.
2199 2013-06-22 Paulo Andrade <pcpa@gnu.org>
2201 * check/lightning.c, configure.ac, include/lightning.h,
2202 lib/lightning.c: Add tests and quirks to build/detect
2203 and/or work on Irix.
2205 * include/lightning/jit_mips.h, lib/jit_mips-cpu.c,
2206 lib/jit_mips-fpu.c, lib/jit_mips.c: Adapt code to run
2207 in big endian mips, using the n32 abi.
2209 2013-06-18 Paulo Andrade <pcpa@gnu.org>
2211 * include/lightning.h: Minor extra preprocessor testing
2212 to "detect" byte order on x86 solaris, that now builds
2213 and pass all test cases.
2215 2013-06-18 Paulo Andrade <pcpa@gnu.org>
2217 * lib/jit_sparc-cpu.c: Correct compiler warning of value
2218 used before assignment. The usage is bogus as the api
2219 requires always patching jumps, but the random value used
2220 could cause an assertion due to invalid displacement.
2222 * lib/jit_sparc.c: Always load and store double arguments
2223 in stack as 2 float loads or stores, for safety, as unaligned
2224 access is not allowed in Sparc Solaris.
2226 2013-06-14 Paulo Andrade <pcpa@gnu.org>
2228 * configure.ac: Force -mlp64 to CFLAGS on HP-UX ia64 port.
2229 It is the only supported mode, and expects gcc as C compiler.
2231 * include/lightning.h, lib/jit_ia64-cpu.c, lib/jit_ia64.c:
2232 Correct ia64 port to work on HP-UX that runs it in big endian
2235 2013-06-10 Paulo Andrade <pcpa@gnu.org>
2237 * lib/jit_hppa.c: Sanitize the cache synchronization inline
2238 assembly code that was doing twice the work and redundantly
2239 flushing the end address every loop iteration.
2241 2013-06-09 Paulo Andrade <pcpa@gnu.org>
2243 * configure.ac, check/Makefile.am, doc/Makefile.am: Do not
2244 explicitly link to -ldl, but instead autodetect the library
2245 with dlopen, dlsym, etc.
2247 * check/lightning.c: Add workaround to apparently buggy
2248 getopt in HP-UX that sets optind to the wrong index, and
2249 use RTLD_NEXT on HP-UX instead of RTLD_DEFAULT to dlsym
2252 * include/lightning.h: Rework definitions of wordsize and
2253 byte order to detect proper values on HP-UX.
2255 * lib/lightning.c: Minor correction to use MAP_ANONYMOUS
2256 instead of MAP_ANON on HP-UX.
2258 * lib/jit_hppa.c: Float arguments must be passed on integer
2259 registers on HP-UX, not only for varargs functions.
2260 Add code to properly clear instruction cache. This was
2261 not required on Debian hppa port, but may have been working
2264 * lib/jit_hppa-cpu.c: Follow pattern of HP-UX binaries and
2265 use bve,n instead of bv,n to return from functions.
2267 * lib/jit_hppa-fpu.c: For some reason "fst? frX,rX,(rY)" did
2268 not work on the tested computer (HP-UX B.11.23 U 9000/785 HP-UX)
2269 so the code was changed, at first for __hpux only to add the
2270 base and offset register and use the instruction with an
2271 immediate (zero) offset.
2273 2013-06-07 Paulo Andrade <pcpa@gnu.org>
2275 * check/lightning.c, lib/jit_disasm.c, lib/jit_ppc-cpu.c,
2276 lib/jit_ppc-fpu.c, lib/jit_ppc.c, include/lightning.h,
2277 include/lightning/jit_ppc.h, include/lightning/jit_private.h:
2278 Adapt code to work on 32 bit AIX ppc using gcc. Most changes
2279 are basically to adapt the elf64 logic to 32 bit, as it does
2280 not use the same convention of 32 bit Darwin ppc.
2282 * check/stack.tst: Add a fake memcpy function to the test
2283 case if running under AIX, as it is not available to dlsym.
2285 * configure.ac: Check for getopt.h header, not available in
2288 2013-06-01 Paulo Andrade <pcpa@gnu.org>
2290 * include/lightning/jit_hppa.h, lib/jit_hppa-cpu.c,
2291 lib/jit_hppa-fpu.c, lib/jit_hppa.c: New files implementing
2292 the hppa port. Built on Debian Linux PA-RISC 2.0, 32 bit.
2294 * check/float.tst: Add preprocessor for hppa expected
2295 values when converting NaN and +-Inf to an integer.
2297 * check/ldst.inc: Ensure double load/store tests use an
2298 8 byte aligned address by default.
2300 * lib/lightning.c: Correct a bug found during tests in
2301 the new port, where qmul* and qdiv* were not properly
2302 setting one of the result registers as modified in the
2303 function, what would be a problem if the only "write"
2304 usage were the qmul* or qdiv*.
2306 * check/varargs.tst, check/varargs.ok: Add one extra
2307 interleaved integer/double test to validate proper code
2308 generation in the extra case.
2310 * check/lightning.c, configure.ac, include/lightning.h,
2311 include/lightning/Makefile.am,
2312 include/lightning/jit_private.h, lib/Makefile.am,
2313 lib/jit_disasm.c: Update for the hppa port.
2315 2013-04-27 Paulo Andrade <pcpa@gnu.org>
2317 * check/varargs.tst: Correct misplaced .align directive
2318 that was causing the double buffer to not be aligned at
2320 * lib/jit_ia64-cpu.c:
2321 Properly implement abi for excess arguments passed on
2323 Simplify load/store with immediate displacement argument
2325 Simplify some calls to "subi" changing to "addi" with
2326 a negative argument.
2327 Remove some #if 0'ed code, that could be useful in
2328 special conditions, but the most useful one would be
2329 to "optimize" "static" jit functions, but for the sake
2330 of simplicity, jit functions are implemented in a way
2331 that can be passed back to C code as C function pointers.
2332 Add an attribute to prototypes of several unused functions.
2333 These functions are defined for the sake of implementing all
2334 Itanium documented instructions, but a significant amount of
2335 them is not used by lightning.
2336 * lib/jit_ia64-fpu.c: Simplify load/store with zero immediate
2337 displacement and add unused attribute for functions not used
2338 by lightning, but required to provide macros implementing all
2339 Itanium documented instructions.
2340 * lib/jit_ia64.c: Update for the properly implemented abi
2341 for stack arguments.
2342 * lib/lightning.c: Mark an unused function as such.
2344 2013-04-27 Paulo Andrade <pcpa@gnu.org>
2347 Correct immediate range check of integer comparisons when
2348 inverting arguments.
2349 Correct gei_u that was not decrementing immediate when
2350 inverting arguments.
2351 Correct b?add* and b?sub* that were not properly updating
2352 the result register.
2354 2013-04-27 Paulo Andrade <pcpa@gnu.org>
2356 * lib/jit_ia64-cpu.c: Correct wrong mapping of 2 instructions
2357 in "M-, stop, M-, stop" translation, that was ignoring the
2358 last stop (implemented as a nop I- stop).
2360 * lib/jit_ia64-fpu.c: Properly implement fnorm.s and fnorm.d,
2361 as well as the proper integer to float or double conversion.
2363 2013-04-27 Paulo Andrade <pcpa@gnu.org>
2365 * lib/jit_ia64-cpu.c: Correct bogus implementation of ldr_T
2366 for signed integers, that was using ld1.s, ld2.s and ld4.s.
2367 The ".s" stands for speculative load, not sign extend.
2369 * lib/jit_ia64-fpu.c: Correct bogus implementation of ldxr_T
2370 for float and double. The third (actually, second) argument
2371 is indeed added to the base register, but the base register
2372 is modified. The actual M7 implementation was already correct,
2373 just the ldxr_f and ldxr_d implementation that was kept in
2374 a prototype state, misinterpreting what M7 does.
2376 2013-04-27 Paulo Andrade <pcpa@gnu.org>
2378 * lib/jit_ia64-cpu.c: Correct X2 pattern matching by preventing
2379 it to attempt to require a stop between the L and the X
2380 instruction; that is, check the registers and predicates
2381 before emitting the L instruction, not after.
2383 * lib/jit_ia64-fpu.c: Slightly simplify and correct
2384 divr_f and divrd_d implementation.
2386 * check/lightning.c: Add __ia64__ preprocessor define
2389 * check/alu.inc, check/clobber.tst, check/float.tst: Define
2390 several macros conditionally to __ia64__. This is required
2391 because __ia64__ jit generation can use way too many memory,
2392 due to not implementing instruction reordering to avoid
2393 as much as possible "stops", what causes way too many nops
2394 to be generated, as well as the fact that division and
2395 remainder requires function calls, and float division
2396 requires significant code to implement.
2398 2013-04-27 Paulo Andrade <pcpa@gnu.org>
2400 * include/lightning.h: Add new backend specific movr_w_d,
2401 movr_d_w and movi_d_w codes as helpers to ia64 varargs
2402 functions arguments.
2404 * lib/jit_ia64-cpu.c:
2405 Correct wrong encoding of A5 small integers.
2406 Correct define of "mux" instruction modifiers.
2407 Correct ordering of arguments and predicates of cmp_xy
2408 implementation with immediate arguments; like most other
2409 codes with an immediate, the immediate is the second, not
2412 * lib/jit_ia64-fpu.c: Actual implementation of the code
2413 to move to/from gpr to/from fpr, to implement varargs abi.
2415 * lib/jit_ia64.c: Make fpr argument registers not allocatable
2416 as temporaries, no need for the extra checks when there are
2419 * lib/jit_print.c, lib/lightning.c: Minor updates for the
2420 new movr_w_d, movr_d_w and movi_d_w codes.
2422 2013-04-26 Paulo Andrade <pcpa@gnu.org>
2424 * lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c: Correct code to
2425 also insert a stop to break an instruction group if a
2426 register is written more than once in the same group.
2427 This may happen if a register is argument and result of
2428 some lightning call (not a real instruction). The most
2429 common case should be code in the pattern:
2433 where "rn" would end up holding "largenum".
2434 But the problem possibly could happen in other circumstances.
2436 2013-04-26 Paulo Andrade <pcpa@gnu.org>
2438 * include/lightning/jit_ia64.h, lib/jit_ia64-cpu.c,
2439 lib/jit_ia64-fpu.c, lib/jit_ia64.c:
2440 Relocate JIT_Rn registers to the local registers, as, like
2441 float registers, div/rem and sqrt are implemented as function
2442 calls, and may overwrite non saved scratch registers.
2443 Change patch_at to receive a jit_code_t instead of a
2444 jit_node_t, so that it is easier to "inline" patches when
2445 some instruction requires complex code to implement, e.g.
2447 Correct arguments to FMA and FMA like instructions that,
2448 due to a cut&paste error were passing the wrong argument
2449 to the related F- implementation function.
2450 Rewrite ltgt to return the proper result if one (or both)
2451 of the arguments is unordered.
2453 2013-04-26 Paulo Andrade <pcpa@gnu.org>
2455 * include/lightning/jit_ia64.h, include/lightning/jit_private.h,
2456 lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c, lib/jit_ia64.c,
2457 lib/lightning.c: Rework code to detect need of a "stop" to
2458 also handle predicates, as if a predicate is written, it
2459 cannot be read in the same instruction group.
2460 Use a single jit_regset_t variable for all registers when
2461 checking need for a stop (increment value by 128 for
2463 Correct wrong "subi" implementation, as the code executed
2464 is r0=im-r1, not r0=r1-im.
2465 Use standard lightning 6 fpr registers, and rework to
2466 use callee save float registers, that may be spill/reloaded
2467 in prolog/epilog. This is required because some jit
2468 instructions implementations need to call functions; currently
2469 integer div/mod and float sqrt, what may change the value of
2470 scratch float registers.
2471 Rework point of "sync" of branches that need to return a
2472 patch'able address, because the need for a "stop" before a
2473 predicate read causes all branches to be the instruction
2474 in slot 0, as there is no template to "stop" and branch
2475 in the same instruction "bundle".
2477 2013-04-25 Paulo Andrade <pcpa@gnu.org>
2479 * include/lightning/jit_ia64.h, lib/jit_ia64-cpu.c,
2480 lib/jit_ia64-fpu.c, lib/jit_ia64.c: New files implementing
2481 the basic infrastructure of an Itanium port. The code
2482 compiles and can generate jit for basic hello world like
2485 * check/lightning.c, configure.ac, include/lightning.h,
2486 include/lightning/Makefile.am, include/lightning/jit_private.h,
2487 lib/Makefile.am, lib/lightning.c: Update for the Itanium
2490 * lib/jit_mips-cpu.c, lib/jit_mips.c: Correct typo and
2491 make the jit_carry register local to the jit_state_t.
2492 This matches code reviewed in the Itanium port, that
2493 should use the same base logic to handle carry/borrow.
2495 2013-04-10 Paulo Andrade <pcpa@gnu.org>
2497 * include/lightning/jit_private.h, lib/jit_arm.c,
2498 lib/jit_mips-cpu.c, lib/jit_mips.c, lib/jit_ppc-cpu.c,
2499 lib/jit_ppc.c, lib/jit_print.c, lib/jit_sparc-cpu.c,
2500 lib/jit_sparc.c, lib/jit_x86-cpu.c, lib/jit_x86.c,
2501 lib/lightning.c: Change all jit_regset macros to take
2502 a pointer argument, to avoid structure copies when
2503 adding a port to an architecture with more than 64
2506 2013-04-08 Paulo Andrade <pcpa@gnu.org>
2508 * lib/jit_arm.c, lib/jit_ppc.c: Do not rely on __clear_cache
2509 aligning to the next page boundary the end argument. It may
2510 actually truncate it.
2512 2013-03-29 Paulo Andrade <pcpa@gnu.org>
2514 * include/lightning/jit_private.h, lib/jit_arm.c, lib/jit_memory.c,
2515 lib/jit_mips.c, lib/jit_ppc.c, lib/jit_sparc.c, lib/jit_x86.c,
2516 lib/lightning.c: Do not start over jit generation if can grow
2517 the code buffer with mremap without moving the base pointer.
2519 2013-03-29 Paulo Andrade <pcpa@gnu.org>
2521 * lib/jit_memory.c: Implement a simple memory allocation wrapper
2522 to allow overriding calls to malloc/calloc/realloc/free, as well
2523 as ensuring all memory containing pointers is zero or points to
2526 * include/lightning.h, include/lightning/jit_private.h: Definitions
2527 for the memory allocation wrapper.
2529 * lib/Makefile.am: Update for new jit_memory.c file.
2531 * lib/jit_arm.c, lib/jit_disasm.c, lib/jit_mips.c, lib/jit_note.c,
2532 lib/jit_ppc.c, lib/jit_sparc.c, lib/jit_x86.c, lib/lightning.c:
2533 Use the new memory allocation wrapper code.
2535 2013-03-22 Paulo Andrade <pcpa@gnu.org>
2537 * configure.ac, include/lightning/jit_private.h, lib/lightning.c:
2538 Remove dependency on gmp. Only a simple bitmap was required, and
2539 that was not enough reason to force linking to gmp and possible
2540 complications caused by it.
2542 2013-03-10 Paulo Andrade <pcpa@gnu.org>
2544 * include/lightning.h: Add check for __powerpc__ defined
2545 in Linux, while Darwin defines __ppc__.
2547 * include/lightning/jit_ppc.h: Adjust register definitions
2548 for Darwin 32 bit and Linux 64 bit ppc usage and/or ABI.
2550 * include/lightning/jit_private.h: Add proper check for
2551 Linux __powerpc__ and an data definition for an workaround
2552 to properly handle code that starts with a jump to a "main"
2555 * lib/jit_disasm.c: Add extra disassembler initialization
2558 * lib/jit_ppc-cpu.c: Add extra macros and functions, and
2559 correct/adapt previous ones to handle powerpc64.
2561 * lib/jit_ppc-fpu.c: Adapt for 64 bit wordsize. Basically
2562 add conversion from/to int32/int64 and proper handling of
2563 load/store offsets too large for 32 bit.
2565 * lib/jit_ppc.c: Add calls to 64 bit codes and adaptation
2566 for the PowerPC 64 bit Linux ABI.
2568 * lib/jit_arm.c, lib/jit_mips.c, lib/jit_sparc, lib/jit_x86.c,
2569 lib/lightning.c: Correct off by one error when restarting jit
2570 of a function due to finding too late that needs to spill/reload
2571 some register. Problem was found by accident on a very special
2572 condition during PowerPC 64 code adaptation.
2574 2013-03-08 Paulo Andrade <pcpa@gnu.org>
2576 * check/lightning.c: Add missing ppc preprocessor definition.
2578 2013-03-06 Paulo Andrade <pcpa@gnu.org>
2580 * check/float.tst: Comment out the int to negative infinity
2581 test in mips for the moment because not all Loongson agrees
2584 * lib/jit_disasm.c: Add a test instead of an assertion
2585 when loading symbols for disassembly due to a failure with
2586 a simple binutils build in Debian mipsel64.
2588 2013-03-06 Paulo Andrade <pcpa@gnu.org>
2590 * include/lightning/jit_private.h, lib/jit_arm-cpu.c,
2591 lib/jit_arm.c, lib/jit_disasm.c, lib/jit_mips-cpu.c,
2592 lib/jit_mips.c, lib/jit_note.c, lib/jit_ppc-cpu.c,
2593 lib/jit_ppc.c, lib/jit_print.c, lib/jit_sparc-cpu.c,
2594 lib/jit_sparc.c, lib/jit_x86-cpu.c, lib/jit_x86.c,
2595 lib/lightning.c: Add an extra structure for data storage
2596 during jit generation, and release it after generating
2597 jit, to reduce a bit memory usage, and also to make it
2598 easier to understand what data is available during
2601 2013-03-06 Paulo Andrade <pcpa@gnu.org>
2603 * lib/lightning.c: Make data and code buffer readonly.
2605 2013-02-20 Paulo Andrade <pcpa@gnu.org>
2607 * doc/body.texi: Fool proof validate the examples of what
2608 an assembly-language programmer would write and correct the
2609 wrong sparc example.
2611 2013-02-19 Paulo Andrade <pcpa@gnu.org>
2613 * doc/body.texi: Add back the SPARC code generation example.
2615 2013-02-19 Paulo Andrade <pcpa@gnu.org>
2617 * check/lightning.c: Remove state flag to work with partial
2618 sparc port, by just disassembling if there was incomplete
2621 * jit_sparc-cpu.c: Correct wrong range check for immediate
2622 integer constants (off by one bit shift).
2623 Correct macro implementing equivalent "rd %y, rd" assembly.
2624 Implement qmul* and qdiv*.
2626 * jit_sparc.c: Update for qmul* and qdiv* and remove logic
2627 to handle incomplete code generation during sparc port.
2629 2013-02-18 Paulo Andrade <pcpa@gnu.org>
2631 * check/float.tst: Add sparc to list of known NaN and +-Inf
2632 to integer conversion.
2634 * check/lightning.c: Define __sparc__ to preprocessor in
2637 * include/lightning/jit_private.h: Correct wrong definition
2638 of emit_stxi_d, that has lived for a long time, but would
2639 cause problems whenever needing to spill/reload a float
2642 * include/lightning/jit_sparc.h: Can only use %g2,%g3,%g4
2643 for scratch variables, as other "global" registers are
2644 reserved for the system, e.g. libc.
2645 Reorder float register naming to make it easier to
2646 access odd float registers, so that generating code for
2647 pusharg and getarg is easier for the IR.
2649 * lib/jit_mips-cpu.c, lib/jit_ppc-cpu.c: Update to match
2650 new code in jit_sparc-cpu.c. It must call jit_get_reg
2651 with jit_class_nospill if using the register to move
2652 an unconditional branch address to it, as the reload
2653 will not happen (actually could happen in the delay
2656 * lib/jit_sparc-cpu.c: Correct wrong macro definition for
2658 Properly implement div* and implement rem. Div* needs
2659 to use the y register, and rem* needs to be synthesized.
2660 Correct b?sub* macro definitions.
2662 * lib/jit_sparc-fpu.c: Correct reversed float to/from double
2664 Correct wrong jit_get_reg call asking for a gpr and then
2665 using the fpr with that number.
2666 Correct wrong branch displacement computation for
2667 conditional branches.
2669 * lib/jit_sparc.c: Correct getarg_d and pushargi_d implementation.
2670 Add rem* entries to the switch converting IR to machine code.
2672 * lib/lightning.c: Correct a problem detected when adding
2673 the jit_class_nospill flag to jit_get_reg, that was caused
2674 when having a branch to an "epilog" node, what would cause
2675 the code to think all registers in unknown state were live,
2676 while in truth, all registers in unknown state in the
2677 "just after return" point are actually dead.
2679 2013-02-17 Paulo Andrade <pcpa@gnu.org>
2681 * include/lightning/jit_sparc.h, lib/jit_sparc-cpu.c,
2682 lib/jit_sparc-fpu.c, lib/jit_sparc.c: New files implementing
2683 the basic framework of the sparc port.
2685 * configure.ac, include/lightning.h, include/lightning/Makefile.am,
2686 include/lightning/jit_private.h, lib/jit_disasm.c: Update
2687 for the sparc port framework.
2689 * lib/jit_mips.c: Correct reversed retr/reti logic.
2691 * lib/jit_ppc.c: Correct misspelled __LITTLE_ENDIAN.
2693 * lib/lightning.c: Always do byte hashing in hash_data, because
2694 the logic to "compress" strings causes large pointers to not
2695 be guaranteed aligned at 4 byte boundaries.
2696 Update for the sparc port framework.
2698 2013-02-11 Paulo Andrade <pcpa@gnu.org>
2700 * lib/jit_arm.c: Correct jit_pushargi_f in the arm hardfp abi.
2701 Most of the logic uses even numbered register numbers, so that
2702 a float and a double can be used in the same register, but
2703 the abi requires packing the float arguments, so jit_pushargi_f
2704 needs to allocate a temporary register to modify only the
2705 proper register argument (or be very smart to push two
2706 immediate arguments if applicable).
2708 2013-02-11 Paulo Andrade <pcpa@gnu.org>
2710 * include/lightning.h, lib/lightning.c: Implement the new
2711 jit_clear_state and jit_destroy_state calls. jit_clear_state
2712 releases all memory not required during jit_execution; that
2713 is, leaves only the mmap'ed data and code buffers allocated.
2714 jit_destroy_state releases the mmap'ed buffers as well as
2715 the jit_state_t object itself, that holds pointers to the
2716 code and data buffers, as well as annotation pointers (for
2717 disassembly or backtrace) in the data buffer.
2719 * lib/jit_note.c: Correct invalid vector offset access.
2721 * check/ccall.c, check/lightning.c, doc/ifib.c, doc/incr.c,
2722 doc/printf.c, doc/rfib.c, doc/rpn.c: Use the new jit_clear_state
2723 and jit_destroy_state calls, to demonstrate the new code to
2724 release all jit memory.
2726 * doc/body.texi: Add basic documentation and usage description
2727 of jit_clear_state and jit_destroy_state.
2729 2013-02-11 Paulo Andrade <pcpa@gnu.org>
2731 * include/lightning/jit_private.h, lib/jit_note.c, lib/lightning.c:
2732 Store all annotation information in the mmap'ed area reserved for
2733 read only data. This adds code to not allocate memory for jit_note_t
2734 objects, and to relocate jit_line_t objects and its contents after
2735 calculating annotation information. The jit_line_t objects are
2736 relocated because it is not possible to always calculate before
2737 hand data layout because note information may be extended or
2738 redundant entries removed, as well as allowed to be added in
2739 non sequential order.
2740 A bug was also corrected in _jit_set_note, that was causing it
2741 to allocate new jit_line_t objects when not needed. It was still
2742 working correctly, but allocating way more memory than required.
2744 2013-02-05 Paulo Andrade <pcpa@gnu.org>
2746 *include/lightning.h, lib/lightning.c: Add the new jit_live code
2747 to explicitly mark a register as live. It is required to avoid
2748 assuming functions always return a value in the gpr and fpr return
2749 register, and to avoid the need of some very specialized codes
2750 that vary too much from backend to backend, to instruct the
2751 optimization code the return register is live.
2753 * lib/jit_arm.c, lib/jit_mips.c, lib/jit_ppc.c, lib/jit_print.c,
2754 lib/jit_x86.c: Update for the new jit_live code.
2756 * check/ret.ok, check/ret.tst: New files implementing a simple
2757 test case that would previously fail at least in ix86/x86_64.
2759 * check/Makefile.am: Update for new "ret" test case.
2761 2013-02-05 Paulo Andrade <pcpa@gnu.org>
2763 * lib/jit_ppc-cpu.c, lib/jit_ppc.c: Validate and correct
2764 problems in the qmul and qdiv ppc implementation.
2766 2013-02-04 Paulo Andrade <pcpa@gnu.org>
2768 * include/lightning.h, include/lightning/jit_private.h,
2769 lib/jit_arm-cpu.c, lib/jit_arm.c, lib/jit_mips-cpu.c,
2770 lib/jit_mips.c, lib/jit_ppc-cpu.c, lib/jit_ppc.c,
2771 lib/jit_x86-cpu.c, lib/jit_x86.c, lib/lightning.c:
2772 Implement the new qmul and qdiv instructions that return signed
2773 and unsigned lo/hi multiplication result and div/rem division result.
2774 These should be useful for jit translation of code that needs to
2775 know if a multiplication overflows (no branch opcode added) or if
2776 a division is exact (easy check if remainder is zero).
2778 * check/lightning.c, lib/jit_print.c, check/Makefile.am,
2779 check/all.tst: Update for the new qmul and qdiv instructions.
2781 * check/qalu.inc, check/qalu_div.ok, check/qalu_div.tst,
2782 check/qalu_mul.ok, check/qalu_mul.tst: New files implementing
2783 simple test cases for qmul and qdiv.
2785 2013-01-30 Paulo Andrade <pcpa@gnu.org>
2787 * doc/body.texi: Correct "jmpi" description that incorrectly
2788 told it was possible to pass any address as jump target. The
2789 only way to do that is "movi+jmpr".
2791 2013-01-30 Paulo Andrade <pcpa@gnu.org>
2793 * lib/jit_x86-cpu.c: Correct undefined behavior code.
2794 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56143
2796 2013-01-29 Paulo Andrade <pcpa@gnu.org>
2798 * configure.ac: Use AC_CONFIG_HEADERS instead of AC_CONFIG_HEADER
2799 to have HAVE_CONFIG_H defined with latest aclocal.
2801 * include/lightning/jit_private.h, lib/lightning.c: Add new
2802 abstraction to use an heuristic to calculate amount of space
2803 required for jit generation, and code to reallocate buffer if
2804 did miscalculate it.
2806 * lib/jit_arm.c, lib/jit_mips.c, lib/jit_ppc.c, lib/jit_x86.c:
2807 Update to use new code to estimate and resize of required buffer
2810 * lib/jit_x86-cpu.c: Minor cosmetic change to avoid adding a
2811 non required rex prefix when calling a function pointer stored
2814 2013-01-24 Paulo Andrade <pcpa@gnu.org>
2816 * check/Makefile.am: "make debug" target should pass only
2817 the main test tool program as argument for running gdb
2819 * configure.ac: Add the --enable-assertions options.
2821 * doc/Makefile.am, doc/body.texi, doc/lightning.texi:
2822 Major rewrite of the documentation to match the current
2825 * doc/version.texi: Automatic date update.
2827 * doc/ifib.c, doc/incr.c, doc/printf.c, doc/rfib.c, doc/rpn.c:
2828 Implementation of the documentation examples, that are also
2829 compiled during a normal build.
2831 * doc/p-lightning.texi, doc/porting.texi, doc/toc.texi,
2832 doc/u-lightning.texi, doc/using.texi: These files were
2833 renamed in the documentation rewrite, as the documentation
2834 was significantly trimmed due to full removal of the porting
2835 chapters. Better porting documentation should be added but
2836 for the moment it was just removed the documentation not
2837 matching the implementation.
2839 2013-01-18 Paulo Andrade <pcpa@gnu.org>
2841 * lib/jit_note.c: Correct bounds check and wrong code keeping
2842 a pointer that could be changed after a realloc call.
2844 2013-01-18 Paulo Andrade <pcpa@gnu.org>
2846 * check/3to2.tst, check/add.tst, check/allocai.tst, check/bp.tst,

2848 check/fib.tst, check/ldsti.tst, check/ldstr-c.tst, check/ldstr.tst,

2853 lib/jit_mips.c, lib/jit_note.c, lib/jit_ppc.c, lib/jit_print.c,
2854 lib/jit_x86.c, lib/lightning.c: Extend the "jit_note" abstraction
2855 with the new "jit_name" call, that receives a string argument, and
2856 should usually be called to mark boundaries of functions of code
2857 generating jit (that is, it is not expected that the language
2858 generating jit map its functions to jit functions).
2860 2013-01-17 Paulo Andrade <pcpa@gnu.org>
2862 * check/add.tst, check/allocai.tst, check/bp.tst, check/divi.tst,
2863 check/fib.tst, check/lightning.c, include/lightning/jit_arm.h,
2864 include/lightning/jit_mips.h, include/lightning/jit_ppc.h,
2865 include/lightning/jit_private.h, include/lightning/jit_x86.h:
2866 Make JIT_RET, JIT_FRET and JIT_SP private. These should not be
2867 used in any operations due to frequently having special
2868 constraints (usually JIT_FRET). JIT_FP must be made available
2869 because it must be used as the base register to access stack
2870 space allocated with jit_allocai.
2872 2013-01-14 Paulo Andrade <pcpa@gnu.org>
2874 * include/lightning.h, lib/lightning.c: Add an extra align
2875 argument to the jit_data call (that should be made private),
2876 so that it should not align strings at 8 bytes.
2877 Correct the jit_note call to include the null ending byte
2878 when adding label/note names to the "jit data section".
2880 2013-01-11 Paulo Andrade <pcpa@gnu.org>
2882 * lib/jit_note.c: New file implementing a simple string+integer
2883 annotation, that should be used to map filename and line number
2884 to offsets in the generated jit.
2886 * include/lightning.h, lib/lightning.c: Update for the new
2888 Add an extra mandatory argument to init_jit, that is used
2889 as argument to bfd_openr.
2890 Change from generic void* to char* the argument to jit_note
2891 and add an extra integer argument, to map to filename and
2894 * check/ccall.c, check/lightning.c, include/lightning/jit_private.h,
2895 lib/jit_arm.c, lib/jit_disasm.c, lib/jit_mips.c, lib/jit_ppc.c,
2896 lib/jit_print.c, lib/jit_x86.c: lib/Makefile.am: Update for the
2897 new annotation code.
2899 * configure.ac, check/Makefile.am: Update to work with latest
2902 2013-01-09 Paulo Andrade <pcpa@gnu.org>
2904 * include/lightning.h, lib/jit_arm.c, jit_mips-fpu.c,
2905 lib/jit_mips.c, lib/jit_print.c, lib/jit_x86.c, lib/lightning.c:
2906 Remove the jit_code_getarg_{f,d} and jit_code_pusharg{i,r}_{f,d}
2907 calls, replacing them with the new, internal only, jit_movr_w_f,
2908 jit_mov{r,i}_f_w, jit_movr_ww_d, and jit_mov{i,r}_d_ww, that
2909 better describe the operation being done, and allow removing
2910 the hackish code to detect special conditions for arm when
2911 moving from/to vfp from/to a grp register pair.
2912 Rename jit_code_retval_{f,d} to jit_code_x86_retval_{f,d} as
2913 it is specific to 32 bit x86, and used to move abi return
2914 value in x87 register to a sse register.
2916 2013-01-05 Paulo Andrade <pcpa@gnu.org>
2918 * check/cccall.c, check/ccall.ok: New test case to validate
2919 interleaved calls from/to C code and jit.
2921 * check/Makefile.am: Update for the new ccall test case.
2923 * include/lightning.h, lib/lightning.c: Add the new jit_address
2924 call that returns the real/final address of a "note" in the
2925 generated jit. It requires a jit_node_t as returned by the
2926 jit_note call, and is only valid after calling jit_emit.
2927 Add an intermediate solution to properly handle arm
2928 soft and softfp modes that move a double to an integer register
2929 pair. Currently it just adds extra tests for the condition,
2930 but the proper solution should be to have extra lightning
2931 codes for these conditions, codes which should be only used
2932 by the backends that need it, and merged with the existing
2935 * include/lightning/jit_private.h: Add new jit_state_t flag
2936 to know it finished jit_emit, so that calls to jit_address
2939 * lib/jit_mips.c: Correct abi implementation so that the
2940 new ccall test case pass. Major problem was using
2941 _jit->function.self.arg{i,f} as boolean values, but that
2942 would cause lightning.c:patch_registers() to incorrectly
2943 assume only one register was used as argument when calling
2944 jit_regarg_p(); _jit->function.self.arg{i,f} must be the
2945 number of registers used as arguments (in all backends).
2947 * lib/jit_x86.c: Add workaround, by marking %rax as used,
2948 to a special condition, when running out of registers and the
2949 allocator trying to spill and reload %rax, but %rax was used
2950 as a pointer to a function, what would cause the reload to
2951 destroy the return value. This condition can be better
2952 generalized, but the current solution is good enough.
2954 * include/lightning/jit_ppc.h, lib/jit_ppc-cpu.c, lib/jit_ppc.c:
2955 Rewrite logic to handle arguments, as the original code was
2956 written based on a SysV pdf about the generic powerpc ABI,
2957 what did "invent" a new abi for the previous test cases, but
2958 failed in the new ccall test in Darwin PPC. Now it properly
2959 handles 13 float registers for arguments, as well as proper
2960 computation of stack offsets when running out of registers
2963 2013-01-02 Paulo Andrade <pcpa@gnu.org>
2965 * check/float.tst: Correct test case to match ppc also
2966 converting positive infinity to 0x7fffffff.
2968 * lib/jit_arm-swf.c: Correct typos with double underscores.
2970 * lib/lightning.c: Correct remaining wrong reverse jump logic.
2972 2012-12-29 Paulo Andrade <pcpa@gnu.org>
2974 * lib/lightning.c: Correct both, wrong and confusing logic
2975 to compute the reverse of a jump. Now it properly matches
2976 C semantics for "eq" (==) and "ne" (!=) and correct computation
2977 of reverse of "uneq" as "gt".
2979 * check/branch.tst: Update "ne" float branch check that
2980 previously happened to be wrongly tested with a NaN argument.
2982 2012-12-29 Paulo Andrade <pcpa@gnu.org>
2984 * check/float.ok, check/float.tst: New test cases implementing
2985 extensive validation of float comparison and branch code
2986 generation as well as integer conversion, involving NaN and
2989 * lib/jit_arm-swf.c, lib/jit_x86-sse.c, lib/jit_x86-x87.c:
2990 Correct bugs found by new float test case.
2992 * lib/jit_x86.c: Correct cut&paste error added in commit to
2993 convert jit_arg* return value to a jit_node_t*, that would
2994 cause it to not properly handle double arguments in ix86.
2996 * check/Makefile.am: Update for the new test case.
2998 2012-12-28 Paulo Andrade <pcpa@gnu.org>
3000 * check/lightning.c, include/lightning.h, lib/jit_arm.c,
3001 lib/jit_mips.c, lib/jit_ppc.c, lib/jit_print.c, lib/jit_x86.c,
3002 lib/lightning.c: Change return value of jit_arg{,_f,_d} to
3003 a jit_node_t* object, that should be used as argument to
3004 jit_getarg_{c,uc,s,us,i,ui,l,f,d}. This just requires changing
3005 from jit_int32_t to jit_pointer_t (or jit_node_t*) the "handle"
3006 for the getarg calls, with the benefit that it makes it easy
3007 to implement patching of the stack address of non register
3008 arguments, this way allowing to implement variable size stack
3009 frames if applicable; useful if there are too many registers and
3010 jit functions uses only a few callee save registers.
3012 2012-12-27 Paulo Andrade <pcpa@gnu.org>
3014 * lib/jit_arm.c, lib/jit_mips-cpu.c, lib/jit_mips.c: Correct
3015 regressions when patching jit_calli for a forward function.
3017 * lib/jit_ppc-cpu.c: Correct wrong arguments to ANDI opcode
3018 in jit_getarg_u{c,s} implementation.
3020 2012-12-23 Paulo Andrade <pcpa@gnu.org>
3022 * check/call.ok, check/call.tst: New test cases to validate
3023 simple typed argument and return values in function calls.
3025 * check/lightning.c: Properly handle jit_movi of labels for
3026 backward and forward code labels.
3028 * check/Makefile.am: Update for new test case.
3030 2012-12-23 Paulo Andrade <pcpa@gnu.org>
3032 * check/carry.ok, check/carry.tst: New test case to validate
3033 carry condition handling.
3035 * check/Makefile.am: Update for new test case.
3037 2012-12-22 Paulo Andrade <pcpa@gnu.org>
3039 * lib/jit_ppc-cpu.c, lib/jit_ppc.c: Implement logic for
3040 jit_htonr for big endian, so that ppc (big endian) pass the
3041 new clobber.tst test case.
3043 2012-12-22 Paulo Andrade <pcpa@gnu.org>
3045 * lib/jit_arm.c: Correct use of wrong argument offset
3046 variable in armv7l or float/double argument for varargs
3047 function in armv7hl.
3048 Correct jit_getarg* logic in software float mode to
3049 match expected behavior in other backends, that is, if
3050 a function is not called, it is safe to use a few lightning
3051 calls before a next jit_getarg* call, as done in the test
3052 case check/stack.tst. The proper solution should be to
3053 extend the parser in lib/lightning.c to check if there is
3054 some float operation that will call some (libgcc?) function,
3055 but software float arm should be a very uncommon backend for
3056 lightning, so, just load the already in place arguments
3057 saved to stack, assuming the register argument was clobbered
3058 (what should not be the case most times...).
3060 2012-12-22 Paulo Andrade <pcpa@gnu.org>
3062 * check/clobber.ok, check/clobber.tst: New test case doing
3063 extensive validation tests to ensure registers not used in
3064 a operation are not clobbered.
3066 * check/Makefile.am: Update for new test case.
3068 2012-12-21 Paulo Andrade <pcpa@gnu.org>
3070 * lib/lightning.c: Partially rewrite/revert code to compute
3071 initial register live state at the start of a basic block.
3072 The original logic was corrupted when adding optimizations
3073 to do as few computations as possible in jit_update. The
3074 reglive field must be always a known set of live registers
3075 at the start of a basic block. The value that was incorrect
3076 was the regmask field, that must be the set of registers
3077 that are in unknown state, because they are not known live,
3078 neither set (or possibly not set) in the basic block, and
3079 *must* store the state at the start of the basic block.
3081 2012-12-20 Paulo Andrade <pcpa@gnu.org>
3083 * include/lightning/jit_ppc.h: Correct mismatch of JIT_F{1,5}
3084 with enum codes, that were correct, and returned by jit_f().
3086 * lib/jit_ppc-cpu.c, lib/jit_ppc-fpu.c, lib/jit_ppc.c: Properly
3087 implement and better describe values when generating stack
3090 2012-12-18 Paulo Andrade <pcpa@gnu.org>
3092 * check/stack.ok, check/stack.tst: New files to test data
3093 integrity on a deep chain of stack frames.
3095 * lib/jit_arm.c, lib/jit_arm-cpu.c, lib/jit_mips.c,
3096 lib/jit_mips-cpu.c, lib/jit_ppc.c, lib/jit_ppc-cpu.c,
3097 lib/jit_x86.c, lib/jit_x86-cpu.c: Calculate _jit->function->stack
3098 in the emit stage, otherwise it will calculate it wrong if
3099 need to jit_allocai space to spill registers.
3101 * lib/lightning.c: Correct wrong offset when updating the
3102 "current" jit function pointer in the code that may need to
3103 allocate stack space to spill registers.
3105 * check/lightning.c: Correct off by one data space check.
3107 * check/Makefile.am: Update for new test case.
3109 2012-12-17 Paulo Andrade <pcpa@gnu.org>
3111 * check/fop_abs.ok, check/fop_abs.tst, check/fop_sqrt.ok,
3112 check/fop_sqrt.tst: New files implementing simple test cases
3113 for the extra float operations.
3115 * check/Makefile.am: Update for new test cases.
3117 * check/alu.inc: Add an extra macro to check for unordered
3118 equality on tests where it is expected to use NaN as an
3121 * check/lightning.c: Minor change for proper/common argument
3122 syntax handling ommiting arguments to options.
3124 2012-12-17 Paulo Andrade <pcpa@gnu.org>
3126 * check/Makefile.am: Automatically generate pattern list
3127 of tests with alternate jit generation options. This should
3128 prevent typos and needing to change multiple places after
3131 2012-12-14 Paulo Andrade <pcpa@gnu.org>
3133 * check/lightning.c: Remove the ".cpu name value" syntax,
3134 as it was not able to do proper changes before the jit
3135 internal data structure was initialized. Now it supports
3136 several getopt options to force using different jit
3137 generation options, effectively replacing the previous
3140 * check/run-test: Add simple extra logic to handle differently
3141 named test scripts, used to test things like x87 coprocessor
3142 in ix86, and arm instruction set or software float in armv7l.
3144 * configure.ac: Add some AC_RUN_IFELSE calls to figure at
3145 compile time if can test different code generation options,
3146 and update Makefile generation accordingly.
3148 * check/Makefile.am, lib/jit_arm.c, lib/jit_x86.c: Update to
3149 properly work with the test tool updating the jit_cpu global
3152 * check/check.arm.sh, check/check.swf.sh, check/check.x87.sh:
3153 New wrapper files passing -mthumb=0, mvfp=0 and -mx87=1 to
3154 the test tool, if applicable, so that it can validate alternate
3155 code generation options on test hosts that support them.
3157 2012-12-14 Paulo Andrade <pcpa@gnu.org>
3159 * lib/jit_x86-x87.c, lib/jit_x86.c: Correct test cases in ix86
3160 when using the x87 coprocessor instead of sse2+.
3162 2012-12-14 Paulo Andrade <pcpa@gnu.org>
3164 * include/lightning.h, include/lightning/jit_private.h,
3165 lib/jit_arm.c, lib/jit_mips.c, lib/jit_ppc.c, lib/jit_x86.c,
3166 lib/lightning.c: Make jit_ellipsis implementation not
3167 backend specific. It is not intended to handle va_list
3168 like objects at runtime, as jit_arg* and jit_getarg*
3169 return constant values resolved at parse time, so, effectively
3170 it is not possible to create printf like jit functions, as
3171 there is no va_start, va_arg, va_end, etc, abstraction. This
3172 limitation should be kept for the sake of making new ports
3175 2012-12-14 Paulo Andrade <pcpa@gnu.org>
3177 * include/lightning.h, lib/lightning.c: Add two extra wrapper
3178 functions to avoid need for excess pointer to/from word casts.
3180 * check/lightning.c: Only need for pointer to/from word cast
3181 now is jit_movi, update accordingly.
3183 2012-12-13 Paulo Andrade <pcpa@gnu.org>
3185 * check/varargs.ok, check/varargs.tst: New test cases implementing
3186 simple varargs calls with a large amount of arguments to exercise
3187 excess arguments on stack.
3189 * include/lightning.h: Include config.h if HAVE_CONFIG_H is
3192 * lib/jit_arm.c: Allocate a fpr register, not a gpr one for
3193 temporary when pushing varargs arguments in the stack.
3195 * lib/jit_arm-swf.c: Correct code changing the wrong offset
3196 in jit_absr_d and jit_negr_d in software float.
3198 * lib/jit_mips.c: Correct calculation of offsets of arguments
3201 * lib/jit_ppc.c: Correct bogus logic for "next" offset of arguments
3202 on stack and adjust for fixed offset of stack arguments.
3204 2012-12-12 Paulo Andrade <pcpa@gnu.org>
3206 * include/lightning.h, lib/jit_arm.c, lib/jit_mips.c,
3207 lib/jit_ppc.c, lib/jit_x86.c, lib/lightning.c: Change jit_prepare
3208 to no longer receive an argument. If receiving an argument, it
3209 should be an ABI specifier, not a boolean if varargs or not,
3210 and add the new jit_ellipsis call, to specify where the
3211 ellipsis is in the C prototype of the function being called.
3212 Note that currently it is not supported to define varargs
3213 functions and it will be ignored if calling jit_ellipsis not
3214 in a prepare/finish* block, but this should be addressed.
3216 * check/allocai.tst, check/alu_add.tst, check/alu_and.tst,
3217 check/alu_com.tst, check/alu_div.tst, check/alu_lsh.tst,
3218 check/alu_mul.tst, check/alu_neg.tst, check/alu_or.tst,
3219 check/alu_rem.tst, check/alu_rsh.tst, check/alu_sub.tst,
3220 check/alu_xor.tst, check/alux_add.tst, check/alux_sub.tst,
3221 check/bp.tst, check/branch.tst, check/cvt.tst, check/divi.tst,
3222 check/fib.tst, check/ldsti.tst, check/ldstr-c.tst,
3223 check/ldstr.tst, check/ldstxi-c.tst, check/ldstxi.tst,
3224 check/ldstxr-c.tst, check/ldstxr.tst, check/rpn.tst,
3225 check/lightning.c: Update for the change to jit_prepare and
3226 addition of jit_ellipsis.
3228 2012-12-11 Paulo Andrade <pcpa@gnu.org>
3230 * lib/jit_ppc-cpu.c: Make movr a function that checks arguments
3231 so that other code can safely assume it is a noop if src and dst
3232 are the same register.
3233 Implement rem{r,i}{,_u} as a div{,u}/mul/sub.
3234 Correct ANDIS, ORIS and XORIS calls to cast the argument to
3235 unsigned before the shift to avoid an assertion if the argument
3236 had the topmost bit set.
3237 Implement lshi, rshi and rshi_u as functions to test for a
3238 zero argument, that would otherwise trigger an assertion when
3239 computing the shift value.
3240 Do a simple implementation of bm{s,c}{r,i} with a temporary,
3241 "andr" of arguments and jump based on comparison with zero.
3242 Correct typo in ldxi_c.
3244 * lib/jit_ppc-fpu.c: Correct wrong arguments to FDIV* and STF*.
3246 * lib/jit_ppc.c: Correct wrong check for 6 instead of 8 integer
3247 arguments in registers. If calling a varargs function and
3248 passing a float or double argument, also either store the
3249 value in the stack or in integer registers, as varargs functions
3250 do not fetch it from float registers.
3251 Add "case" for new functions and incorrectly missing ones.
3252 Call libgcc's __clear_cache, that should know what to do
3253 if the hardware needs flushing cache before execution.
3255 * lib/lightning.c: Do a simple/trivial logic in jit_regset_scan1,
3256 that should make it easier for the compiler to optimize it, and
3257 that also corrects the previously wrong code for big endian, and
3258 that was causing problems in ppc due to not saving all callee save
3259 registers as it was not "finding" them in the regset due to the
3260 little endian assumption bug.
3262 2012-12-11 Paulo Andrade <pcpa@gnu.org>
3264 * configure.ac: Only default to using the builtin disassembler
3265 if on GNU/Linux. This should be temporary, due to requiring
3267 Correctly check $target_cpu for powerpc.
3269 * include/lightning/jit_ppc.h: Correctly implement jit_v_num.
3271 * include/lightning/jit_private.h: Declare proper prototype
3272 for jit_init_debug and jit_finish_debug.
3274 * lib/jit_ppc-cpu.c: Remove code to save/restore callee save
3275 float registers, as it is not required since those float
3276 registers are not usable currently.
3277 Change prolog and epilog generation to, at least comparing
3278 code, match what gcc generates in "gcc -O0", but it is still
3279 failing in Darwin PPC, apparently due to the __clear_cache
3280 call not being enough, as frequently it will also fail to
3281 execute, and the code buffer is all zeroes.
3283 * lib/lightning.c: Do not fail in jit_regset_scan1 calls due
3284 to passing 64 as argument on computers with 64 registers.
3286 2012-12-10 Paulo Andrade <pcpa@gnu.org>
3288 * lib/jit_mips-cpu.c: Correct all current test cases.
3289 Call the "xori" not the "XORI" macro for jit_xori implementation,
3290 as the XORI macro handles only 16 bit unsigned values.
3291 Call the "movr" macro, not the "movi" macro in the special
3292 case of adding or subtracting zero.
3293 Use the proper temporary register in the jit_andr implementation.
3295 2012-12-09 Paulo Andrade <pcpa@gnu.org>
3297 * check/alu.inc, check/alu_add.ok, check/alu_add.tst,
3298 check/alu_and.ok, check/alu_and.tst, check/alu_com.ok,
3299 check/alu_com.tst, check/alu_div.ok, check/alu_div.tst,

3305 check/alu_xor.tst, check/alux_add.ok, check/alux_add.tst,
3306 check/alux_sub.ok, check/alux_sub.tst, check/branch.ok,
3307 check/branch.tst: New test cases for arithmetic and branch
3310 * check/Makefile.am: Update for new test cases.
3312 * include/lightning/jit_private.h: Make the jit_reg_free_p
3313 macro shared by all backends. Previously was added for the
3314 arm backend, but is useful in the x86_64 backend when checking
3315 state of "special purpose register".
3316 Also add the new jit_class_named register class, that must be
3317 or'ed with the register value if calling jit_get_reg expecting
3318 an specific value, because the specific register value may be
3319 zero, that previously was treated as no register requested.
3321 * lib/jit_arm-cpu.c: Correct argument order for T2_MVN.
3323 * lib/jit_arm-swf.c: Call the proper function for double
3324 divide. The "software float" implementation just calls
3327 * lib/jit_arm.c: Return float/double values in the float
3328 register if using the hard float ABI.
3330 * lib/jit_x86-cpu.c: Change the can_sign_extend_int_p macro
3331 to not include -0x80000000L, because there is code that
3332 "abuses" it and thinks it can negate the immediate value
3333 after calling that macro.
3334 Correct implementation of jit_subi that had a wrong code
3335 patch logic doing subtraction with reversed arguments.
3336 Correct REX prefix calculation in the jit_muli implementation.
3337 Correct logic to get/unget %*ax and %*dx registers in divremr
3339 Correct divremi that was using the symbolic, unique %*ax
3340 value in on place (not using the _REGNO name suffix).
3341 Correct cut&paste error causing it to use "xor" instead of
3342 "or" in one code path of the jit_ori implementation.
3343 Correct several flaws when clobbering registers and/or when
3344 one of the arguments was %*cx in the rotshr wrapper function
3345 implementing most shift operations.
3347 * lib/lightning.c: No longer expect that the backend be smart
3348 enough to know what to do when asking for a named register
3349 if that register is already an argument or is live. It fails
3350 if it is an argument, or if register is live, fails if cannot
3352 No longer incorrectly assume that eqr_{f,d} and ltgr_{f,d} are
3353 safe to inverse value tests in jump thread optimization.
3355 2012-12-05 Paulo Andrade <pcpa@gnu.org>
3357 * check/Makefile.am, check/cvt.ok, check/cvt.tst: Add new
3358 "cvt" test case to test conversion from/to int/float types.
3360 * check/lightning.c: Only define truncr_{f,d}_l in 64 bit mode.
3362 * include/lightning.h: Correct typo that caused it to define
3363 jit_truncr_{f,d}_l in 32 bit mode.
3365 * lib/jit_arm-cpu.c: Avoid assertion failure in the signed/unsigned
3366 extend opcodes generation as it shares an interface for 3 argument
3369 * lib/jit_x86-cpu.c: Correct wrong argument passed to
3370 jit_unget_reg in the andi implementation and wrong byte
3371 unsigned extend code generation.
3373 * lib/jit_x86-sse.c: Correct conversion from "word" to float or
3374 double as is dependent on wordsize.
3376 2012-12-05 Paulo Andrade <pcpa@gnu.org>
3378 * check/ldstr-c.ok, check/ldstr-c.tst, check/ldstxi-c.ok,
3379 check/ldstxi-c.tst, check/ldstxr-c.ok, check/ldstxr-c.tst:
3380 New test case files testing load clobbering the base and/or
3383 * check/ldst.inc: New file with common definition for all the
3386 check/Makefile.am, check/ldsti.tst, check/ldstr.tst,
3387 check/ldstxi.tst, check/ldstxr.tst: Update for new common
3388 definitions file and new register clobber ldst tests.
3390 2012-12-05 Paulo Andrade <pcpa@gnu.org>
3392 * lib/jit_mips-fpu.c: Correct wrong register order in stxr_{f,d}
3393 in the mips backend.
3395 2012-12-05 Paulo Andrade <pcpa@gnu.org>
3397 * lib/jit_arm-vfp.c: Correct regression found in armv7l with
3400 2012-12-05 Paulo Andrade <pcpa@gnu.org>
3402 * check/ldstxi.tst, check/ldstxr.tst: Correct wrong argument
3403 order for 32 bit mode tests.
3405 * configure.ac: Correct check for ix86 target_cpu.
3407 2012-12-05 Paulo Andrade <pcpa@gnu.org>
3409 * check/ldstr.ok, check/ldstr.tst, check/ldsti.ok,
3410 check/ldsti.tst, check/ldstxr.ok, check/ldstxr.tst,
3411 check/ldstxi.ok, check/ldstxi.tst:
3412 New test case files exercising a very large amount of
3413 register combinations to verify load/store implementation.
3415 * check/Makefile.am: Update for new test cases.
3417 * lib/jit_x86-cpu.c: Correct wrong argument order when
3418 computing REX prefix for {ld,st}r_T codes;
3420 2012-12-04 Paulo Andrade <pcpa@gnu.org>
3422 * lib/jit_mips-fpu.c, lib/jit_mips.c: Implement missing mips
3423 jit_sqrtr_{f,d} codes.
3425 * check/all.tst, include/lightning.h, lib/jit_print.c: Change
3426 declaration order and call order in all.tst of {add,sub}c and
3427 {add,sub}x. *c must be called before to set the carry and *x
3428 second to use the carry and keep it set. The wrong call order
3429 was causing all.tst to fail in mips, where a register is
3430 allocated to keep a global carry state.
3432 2012-12-04 Paulo Andrade <pcpa@gnu.org>
3434 * include/lightning/jit_mips.h, lib/jit_mips-cpu.c,
3435 lib/jit_mips-fpu.c, lib/jit_mips.c: Correct float/double
3436 argument handling and make the mips backend pass the initial
3439 * include/lightning.h, ib/jit_print.c, lib/lightning.c:
3440 Add extra enum values for argument handling functions that
3441 could not be abstracted to the current codes, that is, when
3442 float values need to move from/to gpr from/to fpr. It would
3443 be more tempting to add such primitives, but they would have
3444 wordsize limitations, and it is not expected to add codes
3445 with one gpr argument for 64 bit and two for 32 bit.
3447 * lib/jit_ppc.c: Check _jit->function before calling jit_epilog()
3448 to avoid a runtime exception.
3450 2012-12-04 Paulo Andrade <pcpa@gnu.org>
3452 * include/lightning/jit_mips.h, lib/jit_mips.c: Update to
3453 make the mips backend compile in a qemu image.
3455 * lib/jit_ppc.c: Minor adaptations to help in having the
3456 ppc backend compilable.
3458 2012-12-03 Paulo Andrade <pcpa@gnu.org>
3460 * configure.ac, include/lightning/jit_private.h, lib/jit_arm-cpu.c,
3461 lib/jit_arm-swf.c, lib/jit_arm.c, check/Makefile.am: Correct
3462 implementation of the arm backend port to build and pass the
3463 current test cases. Tested on armv7 with softfp abi.
3465 * lib/jit_disasm.c: Rename and change prototype of static
3466 disassemble function as in the arm backend it is required
3467 to access state information stored in the jit_state_t object.
3469 * check/3to2.tst, check/add.tst: Correct test case code assuming
3470 JIT_RO and JIT_RET are the same, and even if they are the same,
3471 the logic was incorrect because it must always call jit_retval*
3472 to fetch a function call return before any other instruction.
3473 The arm backend hash a special condition if jit_retval is not
3474 called, because "r0" is not JIT_R0, but is JIT_RET and *also*
3475 the first argument for a called function, so JIT_RET must be
3476 only used as an argument to jit_retval.
3478 2012-12-03 Paulo Andrade <pcpa@gnu.org>
3480 * check/all.tst, check/lightning.c: Only declare or use 64 bit
3481 interfaces on 64 bit builds.
3483 * check/fib.tst: Use simpler logic to not need preprocessor
3484 conditionals for 32 or 64 bit.
3486 * include/lightning.h: Only declare 64 bit macros on a 64 bit
3487 build. Code using lightning must know about wordsize and the
3488 jit generation limitations, also, this way it generates a
3489 compile time failure, not a runtime assertion.
3491 * include/lightning/jit_x86.h: Correct typo in macro name.
3493 * lib/jit_arm.c, lib/jit_arm-cpu.c, lib/jit_mips.c,
3494 lib/jit_mips-cpu.c, lib/jit_ppc.c, lib/jit_ppc-cpu.c,
3495 lib/jit_x86.c, lib/jit_x86-cpu.c: Correct wrong code to get
3496 current jit function pointer.
3498 * lib/lightning.c: Move call to the simplify() optimization
3499 to after register liveness is known. Previous code did work
3500 by accident but now with proper test cases the problem was
3503 * lib/jit_disasm.c: Always cast bfd_vma to long long when
3504 passing it as printf argument.
3506 2012-12-03 Paulo Andrade <pcpa@gnu.org>
3508 * configure.ac, check/Makefile.am, check/check.sh,
3509 doc/Makefile.am, include/lightning/Makefile.am,
3510 lib/Makefile.am: Correct make distcheck.
3512 2012-12-02 Paulo Andrade <pcpa@gnu.org>
3514 * lib/jit_ppc.c: Assign copyright ownership to FSF.
3516 * lib/jit_x86-cpu.c: Correct integer multiplication that was
3517 generating code with reversed register arguments.
3519 * check/rpn.ok, check/rpn.tst: New test case file.
3521 2012-12-02 Paulo Andrade <pcpa@gnu.org>
3523 * lib/jit_x86-cpu.c, lib/jit_x86-sse.c, lib/jit_x86-x87.c:
3524 Actually change copyright owner to FSF as avertised.
3526 * lib/jit_arm-cpu.c, lib/jit_arm-swf.c,
3527 lib/jit_arm-vfp.c, lib/jit_arm.c,
3528 lib/jit_mips-cpu.c, lib/jit_mips-fpu.c, lib/jit_mips.c,
3529 lib/jit_ppc-cpu.c, lib/jit_ppc-fpu.c, lib/jit_ppc.c: New
3530 files implementing initial code different jit backends.
3532 * include/lightning/jit_private.h: Add extra field to the
3533 private jit_patch_t type, required by the arm port.
3535 * lib/Makefile.am: Update for the new backend implementation
3538 2012-12-02 Paulo Andrade <pcpa@gnu.org>
3540 * check/Makefile.am: Add proper "make clean" rule and missing
3541 check.sh to EXTRA_DIST.
3543 2012-12-02 Paulo Andrade <pcpa@gnu.org>
3545 * .gitignore: Update pattern of ignored files.
3547 * check/Makefile.am: Add rule to build liblightning.la dependency
3548 in case of running "make check" before building the library.
3550 2012-12-02 Paulo Andrade <pcpa@gnu.org>
3552 * lightning/Makefile.am, lightning/asm-common.h,
3553 lightning/core-common.h, lightning/fp-common.h,
3554 lightning/funcs-common.h, lightning/i386/Makefile.frag,

3562 lightning/sparc/asm.h, lightning/sparc/core.h,
3563 lightning/sparc/fp.h, lightning/sparc/funcs.h:
3564 Removed. The core logic is used in the new code, and new mips
3565 and arm ports will be added. At first, sparc will not be
3566 supported as it has not yet been ported to the new engine.
3568 2012-12-02 Paulo Andrade <pcpa@gnu.org>
3570 * tests/Makefile.am, tests/3to2.c, tests/3to2.ok, tests/add.c,
3571 tests/add.ok, tests/allocai.c, tests/allocai.ok, tests/bp.c,
3572 tests/bp.ok, tests/divi.c, tests/divi.ok, tests/fib.c, tests/fib.ok,

3579 tests/rpnfp.ok, tests/sete.c, tests/sete.ok, tests/testfp.c,
3580 tests/testfp.ok, tests-run-test: Removed previous test suite, in
3581 favor of a newer one in the check subdirectory.
3583 * check/3to2.ok, check/3to2.tst, check/add.ok, check/add.tst,
3584 check/allocai.ok, check/allocai.tst, check/bp.ok, check/bp.tst,
3585 check/divi.ok, check/divi.tst, check/fib.ok, check/fib.tst:
3586 New sample input for the new test program, loosely matching
3587 several of the previous test cases.
3589 * check/Makefile.am: New test suite makefile.
3591 * check/check.sh, check/run-test: New wrapper files for the
3594 * check/lightning.c: New file. The main driver of the new test
3595 suite, that compiles to a parser of a very simple assembly like
3596 language, generates jit and executes it.
3598 * check/all.tst: New file. A generic debug and sample test file
3599 with a directive to prevent it from being executed, and useful to
3600 read disassembly of all possible instructions, using a fixed set
3603 * include/Makefile.am, include/lightning.h,
3604 include/lightning/Makefile.am, include/lightning/jit_arm.h,
3605 include/lightning/jit_mips.h, include/lightning/jit_ppc.h,

3608 lib/jit_x86-cpu.c, lib/jit_x86-sse.c, lib/jit_x86-x87.c,
3609 lib/jit_x86.c, lib/lightning.c: New files. These files are
3610 written from scratch, only by <pcpa@gnu.org>, and have now
3611 copyright assignment to the FSF. This is the core of the new
3612 lightning rework. Previously it was integrated in code with
3613 a garbage collector and several custom types like vectors and
3614 hash tables, so this first code merge with lightning converts
3615 that code into a library extracting only the jit bits, and at
3616 first only for x86_64 GNU/Linux.
3618 * lightning.h, m4/lightning.m4: Removed. These are no longer
3619 required in the new lightning code.
3621 .gitignore, Makefile.am, configure.ac: Update for the new
3624 2012-12-02 Paulo Andrade <pcpa@gnu.org>
3625 * .cvsignore: Removed for extra cleanup.
3627 * build-aux: Rename directory to m4.
3629 * m4: Renamed to "default" name and for consistency with merge
3630 with code rework to be imported in lightning.
3632 * .gitignore, configure.ac, Makefile.am, doc/Makefile.am:
3633 Update for build-aux to m4 rename.
3635 2012-12-01 Paulo Andrade <pcpa@gnu.org>
3637 * opcode/Makefile.am, opcode/Makefile.in, opcode/ansidecl.h,
3638 opcode/bfd.h, opcode/dis-asm.h, opcode/dis-buf.c, opcode/disass.c,
3639 opcode/i386-dis.c, opcode/i386.h, opcode/ppc-dis.c, opcode/ppc-opc.c,
3640 opcode/ppc.h, opcode/sparc-dis.c, opcode/sparc-opc.c, opcode/sparc.h,
3641 opcode/sysdep.h: Removed. Do not bundle GNU binutils files.
3643 * aclocal.m4, configure, Makefile.in, config.h.in, doc/Makefile.in,
3644 lightning/Makefile.in, tests/Makefile.in: Removed. Do not maintain
3645 autogenerated files that also generate too much diff noise when
3648 * build-aux/help2man, build-aux/texinfo.tex, build-aux/texi2dvi:
3649 Removed. Buildenvironment must have an up to date version from
3652 * build-aux/config.guess, build-aux/config.sub, build-aux/depcomp,
3653 build-aux/install-sh build-aux/mdate-sh build-aux/missing: Removed.
3654 Do not maintain a copy of automake files in git. Release tarballs
3655 must use an up to date version.
3657 * lightningize.in, doc/lightningize.1: Removed. Do not encourage
3658 bundling lightning in other packages. It should use a system package
3659 or a proper thirdy part subdirectory.
3661 * INSTALL: Removed. Autoreconf removes it and creates a symlink
3662 when regenerating files, so, avoid conflicts in git and let
3663 automake create the symlink.
3665 * .gitignore: Add INSTALL and autogenerated files.
3667 * configure.ac, Makefile.am: Update for removal of opcode subdir,
3668 auto generated files and lightningize.
3670 * tests/Makefile.am, tests/3to2.c, tests/add.c, tests/bp.c,
3671 tests/fib.c, tests/fibdelay.c, tests/fibit.c, tests/funcfp.c,
3672 tests/incr.c, tests/printf.c, tests/rpn.c, tests/rpnfp.c,
3673 tests/sete.c, tests/testfp.c: Update for removal of opcode subdir.
3675 * doc/Makefile.am: Update for removal of lightningize.
3677 * configure.ac, lightning/ppc/funcs.h, lightning/sparc/funcs.h,
3678 lightning/i386/fp.h, lightning/i386/core.h, lightning/i386/asm.h,
3679 tests/3to2.c, tests/add.c, tests/bp.c, tests/fib.c, tests/fibdelay.c,
3680 tests/fibit.c, tests/funcfp.c, tests/incr.c, tests/printf.c,
3681 tests/rpn.c, tests/rpnfp.c, tests/sete.c, tests/testfp.c:
3682 Remove LIGHTNING_CROSS, it is half supported and incomplete.
3684 * tests/3to2.c, tests/funcfp.c, tests/rpnfp.c: Remove preprocessor
3685 check on JIT_FPR. If no hardware registers are available, the backend
3686 must provide an alternative for software float.
3688 * lightning/ppc/core.h, lightning/sparc/core.h, tests/Makefile.am:
3689 Remove JIT_NEED_PUSH_POP. It is absolutely not trivial to implement
3690 properly on some backends due to stack alignment constraints, and
3691 whenever it is required, using jit_allocai and using a properly
3692 aligned stack vector, or a heap buffer, is better.
3694 * tests/push-pop.c, tests/push-pop.ok: Removed due to
3695 JIT_NEED_PUSH_POP no longer available.
3697 2011-02-28 Paolo Bonzini <bonzini@gnu.org>
3699 * lightning/i386/core-64.h: Add jit_add{c,x}{i,r}_l, jit_mulr_{l,ul}_,
3700 fix jit_mul{i,r}_{l,ul}.
3702 2010-08-20 Paolo Bonzini <bonzini@gnu.org>
3704 * lightning/i386/fp-64.h: Return patch address from jit_bXYr_{f,d}.
3705 Reported by Paulo César Pereira de Andrade.
3706 * lightning/ppc/fp.h: Likewise.
3707 * lightning/sparc/fp.h: Implement FP branches.

3716 Reported by Paulo César Pereira de Andrade.
3718 2010-08-15 Paolo Bonzini <bonzini@gnu.org>
3720 * tests/ldst.c: Update.
3721 * tests/Makefile.am: Use -ffloat-store to compile it.
3723 2010-08-15 Paolo Bonzini <bonzini@gnu.org>
3725 * lightning/i386/core.h (jit_ldr_c, jit_ldxr_c, jit_ldr_s,
3726 jit_ldxr_s): Move...
3727 * lightning/i386/core-32.h: ... here.
3728 * lightning/i386/core-64.h (jit_ldr_c, jit_ldxr_c, jit_ldr_s):
3729 Use movsbq and movswq.
3731 2010-08-10 Paulo César Pereira de Andrade <pcpa@mandriva.com.br>
3733 * lightning/i386/core-32.h (jit_replace): Use MOVLrr, not MOVLir.
3734 (jit_movbrm): Check index register as well.
3735 * lightning/i386/fp-64.h: Add jit_extr_f_d and jit_extr_d_f.
3736 * lightning/fp-common.h: Add jit_extr_f_d and jit_extr_d_f.
3738 2010-07-28 Paolo Bonzini <bonzini@gnu.org>
3740 * tests/Makefile.am: Add ldst test.
3741 * tests/Makefile.in: Regenerate.
3742 * tests/ldst.c: New.
3743 * tests/ldst.ok: New.
3745 2010-07-28 Paolo Bonzini <bonzini@gnu.org>
3747 * THANKS: Add Paulo Cesar Pereira de Andrade.

3771 2009-03-01 Paolo Bonzini <bonzini@gnu.org>
3773 * lightning/i386/core-64.h: Use Mike's macros for x86-64 too.
3774 * lightning/i386/core.h: Remove jit_replace.
3776 2009-02-27 Mike Spivey <mike@comlab.ox.ac.uk>
3778 * lightning/i386/core.h: Rewrite shift-handling macros.
3779 * lightning/fp-common.h: Fix jit_extr_{f_d,d_f}.
3781 2009-02-17 Mike Spivey <mike@comlab.ox.ac.uk>

3789 2009-02-17 Paolo Bonzini <bonzini@gnu.org>
3791 * lightning/fp-common.h: Define double branches if missing.
3792 * lightning/i386/asm.h: Define JC and JNC mnemonics.

3796 2008-10-09 Paolo Bonzini <bonzini@gnu.org>
3798 * lightning/ppc/funcs.h (jit_flush_code): Subtract 1 from end.
3799 Reported by Eli Barzilay and Matthew Flatt.
3801 2008-08-23 Nix <nix@esperi.org.uk>
3803 * lightning/i386/Makefile.frag: fp-32.h and fp-64.h are target files.
3805 2008-07-02 Laurent Michel <ldm@engr.uconn.edu>
3807 * lightning/ppc/funcs.h (jit_flush_code): modified the computation
3808 of start/end. The pointer arithmetic was done without casting. It
3809 prevented compilation with recent gcc versions.
3810 * lightning/ppc/core.h (jit_pushr_i): The offset for the store was
3811 incorrect. Should have been 4 bytes below SP (not above).
3812 * lightning/ppc/core.h (jit_popr_i): The offset for the load was
3813 incorrect. Should have been 0 (not +8).
3815 2008-06-17 Paolo Bonzini <bonzini@gnu.org>
3817 * lightning/i386/asm-64.h: Forward IMULQir to IMULQirr,

3822 * lightning/i386/core.h: Fix _rN vs. _rR.
3824 2008-06-16 Paolo Bonzini <bonzini@gnu.org>
3826 * lightning/i386/core.h: Use jit_save in jit_replace. Move JIT_R
3828 * lightning/i386/core-32.h: ... here; define jit_save so that
3829 the core.h has no effect on the 32-bit backend.
3830 * lightning/i386/core-64.h: Place JIT_R1/JIT_R2 in R10/R11,
3831 place outgoing arguments in the right spot from the beginning,
3832 define jit_save, fix jit_reg8/jit_reg16.
3834 2008-06-15 Paolo Bonzini <bonzini@gnu.org>
3836 * lightning/i386/core-64.h: Rewrite argument passing to
3837 support up to 6 arguments and generate less code.
3839 2008-06-14 Laurent Michel <ldm@thorgal.homelinux.org>
3841 * lightning/i386/core-64.h (jit_movi_l): When the operand is 0,
3842 the XOR should be on a quadword.
3843 * lightning/i386/core-64.h (jit_prolog): Keep 16-byte stack
3845 (jit_ret): Always use LEAVE.
3847 2008-06-13 Laurent Michel <ldm@thorgal.homelinux.org>
3849 * lightning/i386/core-64.h: Add (void) casts for C++ compatibility.
3850 * lightning/i386/asm.h: Likewise.
3852 2008-06-12 Paolo Bonzini <bonzini@gnu.org>
3854 * lightning/i386/core.h: Move JIT_V definition...
3855 * lightning/i386/core-32.h: ... here.
3856 * lightning/i386/core-64.h: ... and here. Avoid dancing between
3857 RSI/RDI and R12/R13, and place JIT_V1/JIT_V2 in R12/R13.
3859 2008-06-11 Paolo Bonzini <bonzini@gnu.org>
3861 * build-aux/lightning.m4: Adjust LIGHTNING_BACKENDS, don't
3862 use suffix support to distinguish i386/x86_64.
3863 * lightning/i386/Makefile.frag: Use LIGHTNING_TARGET_FILES
3864 to distribute *-32.h and *-64.h files now.
3865 * lightning/i386/asm-i386: Moved to...
