- * include/lightning/jit_private.h: Add new register classes to
- flag float registers and double only registers, required for sparc64
- where only low 32 bit fpr registers can be used for single precision
- operations.
- Add new 128 bit jit_regset_t type for sparc64 register set.

+ https://gitlab.com/wingo/lightening
- * check/lightning.c, include/lightning.h: Add the new jit_va_push
- interface. That should be called when passing a va_list to a C
- function. This is required because on Alpha a va_list is passed
- by value, and lightning does not know about data types, so, cannot
- understand it is pushing a va_list as argument.
-
- * lib/jit_names.c, lib/lightning.c: Minor changes for the new
- jit_code_va_push.
-
- * check/cva_list.c: Update only test case using jit_va_push, to
- pass a va_list to a C function.
-
- doc/body.texi: Better documentation of the varargs interface.
-
- * jit_alpha.c, jit_alpha-cpu.c: Update to properly push a
- C va_list and correctly calculate varargs offset.
-
- * lib/jit_aarch64-sz.c, lib/jit_aarch64.c, lib/jit_alpha-sz.c,
- lib/jit_arm-sz.c, lib/jit_arm.c, lib/jit_hppa-sz.c, lib/jit_hppa.c,
- lib/jit_ia64-sz.c, lib/jit_ia64.c, lib/jit_mips-sz.c, lib/jit_mips.c,
- lib/jit_ppc-sz.c, lib/jit_ppc.c, lib/jit_s390-sz.c, lib/jit_s390.c,
- lib/jit_sparc-sz.c, lib/jit_sparc.c, lib/jit_x86-sz.c, lib/jit_x86.c:
- Update for the new jit_va_push interface.
-
-2018-02-22 Paulo Andrade <address@hidden>
-
- * lib/jit_alpha-cpu.c: Always set t12 to the address of the
- current function, to properly work on all systems. Previously
- the shortcut did only work on Tru64. For Linux and glibc the
- change is required.
-
-2018-02-22 Paulo Andrade <address@hidden>
-
- * lib/jit_aarch64.c, lib/jit_alpha.c, lib/jit_arm.c,
- lib/jit_mips.c, lib/jit_ppc.c, lib/jit_sparc.c, lib/jit_x86.c:
- Correct wrong logic in usage of jit_live in jit_retr. The
- problem is that if a temporary is required during epilog,
- the return register might be allocated, so, jit_live must always
- be used.
-
-2018-01-31 Paulo Andrade <address@hidden>
-
- * lib/lightning.c: Avoid deep recursions when computing live
- register ranges.
-
-2018-01-31 Paulo Andrade <address@hidden>
-
- * lib/jit_mips-cpu.c: Correct frame size and varargs
- initialization for the n32 abi.
- * lib/jit_mips.c, lib/jit_mips-fpu.c: Correct 32 bit abis
- in big-endian.
-
-2017-09-13 Paulo Andrade <address@hidden>
-
- * configure.ac: Add check for binutils 2.29 prototype to the
- disassembler function.
- * lib/jit_disasm.c: Adapt for binutils 2.29 change.
-
-2017-06-09 Paulo Andrade <address@hidden>
-
- * include/lightning/jit_private.h, lib/lightning.c: Add a
- second pass from start when computing register live ranges.
- This should be used temporarily, and is required for certain
- loop constructs, with several consecutive blocks not referencing
- a live register.
-
-2016-05-05 Paulo Andrade <address@hidden>
-
- * lib/lightning.c: Correct wrong movr simplification,
- remove no longer needed code to set return registers live
- and update live register set when reaching a label boundary,
- but do not descend if the block has been already visited.
- The later need some tuning for complex code generation, where
- it will still have issues.
-
-2015-11-30 Paulo Andrade <address@hidden>
-
- * doc/body.texi: Change documentation to no longer say
- it is a variant of the Fibonacci sequence, and document
- a proper implementation.
- Thanks to Jon Arintok for pointing out that the Fibonacci
- sequence generation was incorrect. It was documented, but
- still confusing.
-
- * check/fib.tst, check/fib.ok, check/bp.tst, check/bp.ok,
- doc/ifib.c, doc/rbif.c: Implement a proper Fibonacci
- sequence implementation.
-
-2015-07-03 Paulo Andrade <address@hidden>
-
- * lib/jit_mips-cpu.c: Correct definition of htonr_ul.
- Correct prolog/epilog/va* routines to work on o64 abi.
-
- * lib/jit_mips-fpu.c: Correct load of double literal
- argument when not using a data buffer.
- Remove alignment correction in vaarg_d if using the
- new mips abi.
-
- * lib/jit_mips.c: Correct code to allow creating variadic
- jit functions when using the new mips abi.
-
- * lib/jit_rewind.c: Minor adjust for rewind when using
- the new mips abi, if there are varargs arguments in
- registers.
-
-2015-06-06 Paulo Andrade <address@hidden>
-
- * lib/jit_ia64-cpu.c: Search backward for the last output
- register used, otherwise would stop too early if a float
- argument used the slot.
- Correct offset of first va_list argument, and use proper
- va_list abi.
-
- * lib/jit_ia64-fpu.c: Add new functions to move a gpr
- to a fpr register, to counterpart the ones that move a
- fpr to a gpr. These are required to properly implement
- jit_getarg*_{f,d} on complex prototypes, or variadic
- jit functions.
-
- * lib/jit_ia64-sz.c: Update for support to jit variadic
- functions.
-
- * lib/jit_ia64.c: Implement proper abi for variadic
- jit functions.
-
-2015-06-04 Paulo Andrade <address@hidden>
-
- * lib/jit_rewind.c: New file implementing generic functions
- to "rewind", or rewrite IR code sequences.
-
- * include/lightning.h: Add several new codes, that previously
- were a function call, that would synthesize the operation.
- Now, there is a code for the operation, and a new flag to
- know an operation is synthesized.
-
- * include/lightning/jit_private.h: Add several new macros to
- help construct synthesized IR code sequences.
-
- * lib/Makefile.am: Update for lib/jit_rewind.c.
-
- * lib/jit_disasm.c: Update for a small rework on jit_node_t,
- so that --enable-devel-disassembler does not need a change
- in the layout of jit_node_t.
-
- * lib/jit_names.c: Update for the new codes.
-
- * lib/jit_print.c: Update to print more readable output, and
- flag synthesized IR code sequences.
-
- * lib/jit_aarch64-sz.c, lib/jit_aarch64.c,
- lib/jit_arm-sz.c, lib/jit_arm.c, lib/jit_x86-sz.c,
- lib/jit_x86.c: Update for new synthesized IR code sequences.
-
- * lib/jit_ppc-cpu.c, lib/jit_ppc-fpu., lib/jit_ppc-sz.c,
- lib/jit_ppc.c, lib/jit_mips-cpu.c, lib/jit_mips-fpu.c,
- lib/jit_mips-sz.c, lib/jit_mips.c, lib/jit_s390-fpu.c,
- lib/jit_s390-sz.c, lib/jit_s390.c: Update for new synthesized
- IR code sequences and correct bugs in the initial varargs
- implementation support.
-
- * lib/jit_alpha-sz.c, lib/jit_alpha.c, lib/jit_hppa-sz.c,
- lib/jit_hppa.c, lib/jit_ia64-sz.c, lib/jit_ia64.c,
- lib/jit_sparc-sz.c, lib/jit_sparc.c: Add generic, untested
- support for the new synthesized IR code sequences. Known
- most likely broken right now, and should be corrected once
- access to these hosts is available.
-
- * lib/lightning.c: Update for new IR codes, and add support
- for not yet existing instructions that change third argument.
-
- * size.c: Change to use different tables for LE and BE PowerPC.
- Correct a wrong endif for x32.
-
-2015-05-25 Paulo Andrade <address@hidden>
-
- * check/cva_list.c: New file implementing a test to ensure
- the value returned by jit_va_start is a valid C va_list.
-
- * check/va_list.ok: New simple helper file, as now the
- va_list.tst test is enabled.
-
- * check/va_list.tst: Rewritten for an extensive variadic
- jit functions test.
-
- * check/Makefile.am: Update for the new tests.
-
- * lib/jit_arm-cpu.c, lib/jit_arm-swf.c, lib/jit_arm-vfp.c,
- lib/jit_arm.c: Correct broken software float in a previous
- commit. Note that the hard float abi implementation is known
- broken at this time, for special cases involving variadic
- functions, and should be corrected next.
-
- lib/jit_x86-cpu.c, lib/jit_x86-sz.c, lib/jit_x86.c: Correct
- the jit_va_list_t semantics to match C va_list.
-
-2015-05-24 Paulo Andrade <address@hidden>
-
- * lib/Makefile.am: Bump library major. This is a preparation
- for a rework that was due for quite some time, but that is
- now required to properly implement variadic jit functions.
- The rework is mainly required to know at prolog parsing, if
- a function is variadic or not. This will benefit a few
- backends, and is mandatory for the hard float arm abi.
- The rework was already planned for quite some time, to
- be able to use a variable stack framesize, and for leaf
- functions optimization where applicable.
- The change will be source compatible, but will change
- some internals, and jit_code_t values, as some new will
- be added.
- The only behavior change is that, jit_arg_register_p may
- change return value on hard float arm abi, if called before
- or after jit_ellipsis. Common sense anyway, would say to
- make that call after jit_ellipsis, but documentation
- should be updated for it.
-
-2015-05-24 Paulo Andrade <address@hidden>
-
- * lib/jit_aarch64-fpu.c, lib/jit_aarch64.c: Correct base
- aarch64 varargs code.
-
-2015-05-24 Paulo Andrade <address@hidden>
-
- * check/lightning.c: Clearly run check if clang is the system
- compiler.
-
-2015-05-20 Paulo Andrade <address@hidden>
-
- * lib/jit_sparc-cpu.c, lib/jit_sparc-fpu.c, lib/jit_sparc.c:
- Add base support to jit vararg functions to the sparc backend.
-
-2015-05-20 Paulo Andrade <address@hidden>
-
- * lib/jit_alpha-cpu.c, lib/jit_alpha-fpu.c, lib/jit_alpha.c:
- Add base support to jit vararg functions to the alpha backend.
-
-2015-05-19 Paulo Andrade <address@hidden>
-
- * lib/jit_hppa-cpu.c, lib/jit_hppa-fpu.c, lib/jit_hppa.c:
- Add base support to jit vararg functions to the hppa backend.
-
-2015-05-10 Paulo Andrade <address@hidden>
-
- * lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c, lib/jit_ia64.c:
- Add base support to jit vararg functions to the ia64 backend.
-
-2015-05-10 Paulo Andrade <address@hidden>
-
- * lib/jit_ia64-fpu.c, lib/jit_ia64.c: Correct movi_d_w
- and movi_f_w implementation to work when not using a
- data buffer. This causes the check varargs.tst to
- work when passing "-d" to the lightning test tool.
-
-2015-05-10 Paulo Andrade <address@hidden>
-
- * lib/jit_ia64.c: Implement inline assembly cache flush,
- required on multiprocessor systems.
-
-2015-05-06 Paulo Andrade <address@hidden>
-
- * lib/jit_mips-cpu.c, lib/jit_mips-fpu.c, lib/jit_mips.c:
- Add base support to jit vararg functions to the mips backend.
- Currently only supported on the o32 abi, until access to a
- n32 system is arranged.
-
-2015-05-05 Paulo Andrade <address@hidden>
-
- * lib/jit_ppc-cpu.c, lib/jit_ppc-fpu.c, lib/jit_ppc.c:
- Add base support to jit vararg functions to the PowerPC backend.
-
-2015-05-02 Paulo Andrade <address@hidden>
-
- * lib/jit_s390-cpu.c, lib/jit_s390-fpu.c, lib/jit_s390.c:
- Add base support to jit vararg functions to the s390 backend.
-
-2015-05-01 Paulo Andrade <address@hidden>
-
- * lib/jit_arm-cpu.c, lib/jit_arm-swf.c, lib/jit_arm-vfp.c,
- lib/jit_arm.c: Add base support to jit vararg
- functions to the arm backend.
-
-2015-04-30 Paulo Andrade <address@hidden>
-
- * lib/jit_aarch64-cpu.c, lib/jit_aarch64-fpu.c,
- lib/jit_aarch64.c: Add base support to jit vararg
- functions to the aarch64 backend.
-
-2015-04-27 Paulo Andrade <address@hidden>
-
- * include/lightning.h, include/lightning/jit_private.h,
- lib/jit_names.c, lib/lightning.c: Add initial support
- for the new jit_va_start, jit_va_arg, jit_va_arg_d, and
- jit_va_end interfaces. The jit_va_start call is supposed
- to return a va_list compatible pointer, but not yet
- decided if it will be "declared" stdarg compatible,
- as for now only x86 support has been added (and should
- be compatible), but issues may arise on other backends.
-
- * check/lightning.c: Add wrappers to call the new jit_va_*
- interfaces.
-
- * lib/jit_x86-cpu.c, lib/jit_x86.c: Implement the new
- jit_va_* for x86.
-
- * lib/jit_x86-sz.c: Add fields, but not yet fully updated,
- as this is an intermediate commit.
-
- * lib/jit_aarch64-sz.c, lib/jit_aarch64.c,
- lib/jit_alpha-sz.c, lib/jit_alpha.c,
- lib/jit_arm-sz.c, lib/jit_arm.c,
- lib/jit_hppa-sz.c, lib/jit_hppa.c,
- lib/jit_ia64-sz.c, lib/jit_ia64.c,
- lib/jit_mips-sz.c, lib/jit_mips.c,
- lib/jit_ppc-sz.c, lib/jit_ppc.c,
- lib/jit_s390-sz.c, lib/jit_s390.c,
- lib/jit_sparc-sz.c, lib/jit_sparc.c: Prepare for the
- new jit_va_* interfaces. Not yet implemented, and will
- cause an assertion if used.
-
- * check/va_list.tst: Simple early test case, that works
- on x86_64, x32, ix86, cygwin, and cygwin64.
-
-2015-02-17 Paulo Andrade <address@hidden>
-
- * include/lightning.h, include/lightning/jit_private.h,
- lib/jit_aarch64-cpu.c, lib/jit_aarch64.c,
- lib/jit_alpha-cpu.c, lib/jit_alpha.c,
- lib/jit_arm-cpu.c, lib/jit_arm.c,
- lib/jit_hppa-cpu.c, lib/jit_hppa.c,

- lib/jit_ppc-cpu.c, lib/jit_ppc.c,
- lib/jit_s390-cpu.c, lib/jit_s390.c,
- lib/jit_sparc-cpu.c, lib/jit_sparc.c,
- lib/jit_x86-cpu.c, lib/jit_x86.c: Implement the new
- jit_allocar(offs, size) interface, that receives
- two integer registers arguments, allocates space
- dynamically in the stack, returns the offset in
- the first argument, and uses the second argument
- for the size in bytes of the memory to be allocated.
-
- * check/allocar.ok, check/allocar.tst: New files
- implementing test cases for the new jit_allocar
- interface.
-
- * check/Makefile.am, check/lightning.c: Update for
- the new test case and interface.
-
- * doc/body.texi: Add documentation of the new
- interface.
-
-2015-02-17 Paulo Andrade <address@hidden>
-
- * include/lightning/jit_x86.h, lib/jit_x86-cpu.c,
- lib/jit_x86-x87.c: No longer make st(7) available.
- Need to keep one x87 slots empty to avoid exceptions.
- This has the side effect of no longer needing the
- hackish emms instruction before a function call.
-
-2015-02-16 Paulo Andrade <address@hidden>
-
- * lib/lightning.c: Remove the jit_regno_patch bitfield
- register fields before actual emit, as it is only really
- used before emit, otherwise, on special conditions it
- may consider live registers as dead during code emit.
-
-2015-02-15 Paulo Andrade <address@hidden>
-
- * lib/jit_x86-cpu.c, lib/jit_x86-sse.c, lib/jit_x86-x87.c:
- Correct encoding of ldxr* stxr* in the x32 abi. If the
- displacement register is negative, it would generate
- a 64 bit instruction with a 32 bit unsigned displacement.
-
- * check/ranger.tst, check/ranger.ok: New files, implementing
- a test case for negative loads and stores. This is range.tst
- converted to use registers instead of immediate offsets.
-
- check/Makefile.am: Update for the new test case.
-
-2015-02-07 Paulo Andrade <address@hidden>
-
- * lib/jit_size.c: Preventively use at least 144 bytes
- if JIT_INSTR_MAX is less than it. The logic is not
- guaranteed to be 100% precise, it is mostly heuristics
- to allocate a buffer with as close as possible size,
- but a wrong value may cause code generation to write
- past the end of the buffer.
-
-2015-02-03 Paulo Andrade <address@hidden>
-
- * lib/lightning.c: Correct the reason the bug in
- simplify_stxi was not triggered before, it was due to
- incorrectly resetting the value->code field, what was
- causing it to never properly optimize:
- stxi Im0 Rb0 Rt0
- ldxi Rt1 Rb1 Im1
- when Rb0 == Rb1, Rt0 == Rt1 and Im0 == Im1
- There was another possible issue, that has been also
- addressed in this commit, that would be the case of
- Rbn == Rtn, where no redundancy removal is possible.
-
-2015-02-03 Paulo Andrade <address@hidden>
-
- * lib/lightning.c: Correct wrong check in simplify_stxi.
- The test was incorrectly comparing the target register
- and the displacement offset. This was a time bomb bug,
- that would trigger in code like:
- stxi Im0 Rb0 Rt0
- stxi Im1 Rb1 Rt1
- if Rb0 == Rb1 && Rt0 == Rt1 && Im0 == Rt1, that is,
- the wrong check was Im0 == Rt1, instead of the supposed
- Im0 == Imm1 (that was what the code mean't to do). It
- was removing the second stxi assuming it was redundantly
- generated; as that is not uncommon pattern on
- translators generating jit.
-
-2015-02-02 Paulo Andrade <address@hidden>
-
- * configure.ac, include/lightning/jit_private.h,
- lib/jit_aarch64.c, lib/jit_alpha.c, lib/jit_arm.c,
- lib/jit_disasm.c, lib/jit_hppa.c, lib/jit_ia64.c,
- lib/jit_mips.c, lib/jit_ppc.c, lib/jit_print.c,
- lib/jit_s390.c, lib/jit_sparc.c, lib/jit_x86.c: Add a new
- --enable-devel-disassembler option, that should be used
- during development, or lightning debug. This option
- intermixes previous jit_print and jit_disassemble
- output, making it easier to visualize what lightning
- call was used, and what code was generated.
-
-2015-01-31 Paulo Andrade <address@hidden>
-
- * lib/jit_arm-cpu.c, lib/jit_arm.c: Only limit to 24 bit
- displacement non conditional jump in the same jit_state_t.
-
-2015-01-19 Paulo Andrade <address@hidden>
-
- * doc/body.texi: Reorder documentation, making jit_frame
- and jit_tramp the lightning response to the need of
- trampolines, continuations and tail call optimizations.
- A pseudo code example of a factorial function was added.
- Also added a section for description of the available
- predicates.
-
- * doc/fact.c: New file, implementing a simple example of
- a translation of a trivial, recursive, tail call optimization
- into lightning calls. This is the conversion to functional C
- code of the example in doc/body.texi.
-
- * doc/Makefile.am: Update for the next test case.
-
-2015-01-17 Paulo Andrade <address@hidden>
-
- * include/lightning.h, lib/jit_aarch64.c,
- lib/jit_alpha.c, lib/jit_arm-vfp.c, lib/jit_arm.c,
- lib/jit_hppa.c, lib/jit_ia64.c, lib/jit_mips.c,
- lib/jit_ppc.c, lib/jit_s390.c, lib/jit_sparc.c,
- lib/jit_x86.c: Add the new jit_arg_register_p predicate.
- The predicate is expected to be used to know if an
- argument is in a register, what would need special
- handling if code that can overwrite non callee save
- registers is executed.
-
- * check/carg.c: New test case to check consistency and
- expected usage of jit_arg_register_p.
-
- * check/Makefile.am: Update for new test case.
-
-2015-01-17 Paulo Andrade <address@hidden>

- include/lightning/jit_alpha.h,
- include/lightning/jit_arm.h,
- include/lightning/jit_hppa.h,
- include/lightning/jit_mips.h,

- lib/jit_ia64.c, lib/jit_mips.c,
- lib/jit_ppc.c, lib/jit_s390.c,
- lib/jit_sparc.c, lib/jit_x86.c: Remove jit_arg_reg_p and
- jit_arg_f_reg_p from a public header, and define it only
- on port specific files where an integer offset is used
- to qualify an argument identifier. Exported code expects
- an opaque pointer (but of jit_node_t* type) to "qualify"
- an argument identifier.
- This patch, and the code review/simplification done during
- it also corrected some bugs:
- o Inconsistent jit_arg_d value of double argument after 3
- integer arguments in arm for jit_functions; tested, C
- functions were being properly called.
- o Inconsistent use of getarg_{f,d} and putarg*_{f,d} on
- s390 (32-bit) that happened to not have a proper test
- case, as it would only happen for jit functions, and
- tested, called C functions had proper arguments.
- o Corrected a "last minute" correction that did not go
- to the committed version, and would not compile on hppa,
- due to bad _jit_putargi_d prototype definition.
-
-2015-01-17 Paulo Andrade <address@hidden>
-
- * doc/body.texi: Correct wrong/outdated information for
- hton*, pusharg* and ret*, and add missing documentation
- for rsb*, qmul*, qdvi* and putarg*.
-
-2015-01-15 Paulo Andrade <address@hidden>
-
- * configure.ac, lib/jit_disasm.c: Rewrite workaround
- to apparent problem to initialize powerpc disassembler.

- lib/jit_s390.c, lib/jit_sparc.c, lib/jit_x86.c:
- Implement jit_putarg*. It works as a mix of jit_getarg*
- and jit_pusharg*, in the way that the first argument is
- a register or immediate, and the second is a pointer
- returned by jit_arg*. The use of the interface is to change
- values of arguments to the current jit function.
-
- * check/put.ok, check/put.tst: New test cases exercising
- the new jit_putarg* interface.
-
- * check/Makefile.am, check/lightning.c: Update for the
- new test case and interface.

- Add support for generating jit for s390 32 bit. This change

- lib/jit_s390x.c, lib/jit_sparc.c, lib/jit_x86.c: Add an
- assertion to all code generation "drivers" to ensure
- _jitc->regarg is empty or in an expected state, after
- translation of a lightning instruction to native code.
- This change was a brute force test to find out other cases
- of a temporary not being release (like was happening with

- after running make check, with assertions enabled, on all
- backends.

-
- * lib/jit_ia64.c, lib/jit_ppc.c: Correct handling of function
- descriptor when first prolog is a jit_tramp prolog. The
- test case was using the same jit_context_t, so was not
- triggering this condition.
-
- * lib/jit_ppc-cpu.c: Properly handle jump displacements that
- do not fit on 24 powerpc. This required changing from previous
- "mtlr reg, blr" to "mtctr reg, bctr" to properly handle
- the logic to "hide" function descriptors, but that would
- also be required as the proper jit_jmpr when/if implementing
- optimizations to leaf functions (was working with blr because
- it is saved/reloaded in prolog/epilog).
-
-2014-10-21 Paulo Andrade <address@hidden>
-
- * include/lightning.h, lib/lightning.c: Add three predicates
- to query information about labels. jit_forward_p(label)
- will return non zero if the label is "forward", that is
- need a call to jit_link(label), jit_indirect_p(label)
- that returns non zero if the label was created with the
- jit_indirect() call, and jit_target_p(label) that will
- return non zero if there is at least one jump patched
- to land at that label.

-2014-10-18 Paulo Andrade <address@hidden>
-
- * check/range.ok, check/range.tst: New test case designed
- to catch incorrect code generation, usually due to incorrect
- test of immediate size. The test checks a large amount of
- encodings in "power of two" boundaries. This test exorcises
- a significant amount of code paths that was previously not
- tested.
-
- * check/Makefile.am: Add range test to make check target.
-
- * lib/jit_aarch64-cpu.c: Correct wrong address calculation
- for stxi_c, stxi_s, stxi_i and stxi_l when the offset is
- too large.
-
- * lib/jit_mips-fpu.c: Correct wrong size test to check if
- an immediate can be encoded in a float or double store.
-
- * lib/jit_s390x-cpu.c: Correct inverted encoding to stxi_s
- when the offset cannot be encoded, and fallbacks to an
- alternate encoding in 2 instructions.

- lib/jit_x86.c, lib/lightning.c: Implement jit_rsb*. This
- was a missing lightning 1.x interface, that on most
- backends is synthesized, but on a few backends (hppa and ia64),
- it can generate better code as on those there is, or the
- only instruction with an immediate is in "rsb" format

- next instruction. In most backends the only value that makes
- a difference is a value that matches sizeof(void*), as all
- other values usually are already automatically aligned in

- lib/jit_ppc-cpu.c, lib/jit_s390x-cpu.c, lib/jit_sparc-cpu.c,
- lib/jit_x86-cpu.c, lib/lightning.c: Implement the new
- jit_frame and jit_tramp interfaces, that allow writing
- trampoline like calls, where a single dispatcher jit buffer
- is written, and later other jit buffers are created, with
- the same stack frame layout as the dispatcher. This is the
- logic that GNU Smalltalk used in lightning 1.x, and is required
- to make a sane port for lighting 2.x.
-
- * jit_ia64-cpu.c: Implement support for jit_frame and jit_tramp,
- and also correct wrong encoding for B4 instructions, that
- implement jmpr, as well as correct reverse logic in _jmpr,
- that was moving the branch register to the jump register,
- and not vice-versa.
- Also, if a stack frame is to be assumed, always assume it may
- call a function with up to 8 arguments, regardless of the
- hint frame argument.
-
- * lib/jit_arm.c: Add a new must_align_p() interface to ensure
- function prologs are always aligned. This condition was
- previously always true, somewhat by accident, but with
- jit_tramp it is not guaranteed.
-
- * jit_ia64-cpu.c: lib/jit_ppc.c: Add minor special handling
- required to implement jit_tramp, where a function descriptor
- should not be added before a prolog, as jit_tramp means omit
- prolog.
-
- * check/lightning.c: Update test driver for the new interfaces.
-
- * check/Makefile.am, check/tramp.tst, check/tramp.ok: Add
- a simple test and example of the jit_frame and jit_tramp
- usage implementing a simple Fibonacci function using a
- simulation of an interpreter stack and how it would handle
- state in language specific variables.
-
- * doc/body.texi: Add documentation for jit_frame and

- lib/jit_x86.c, lib/lightning.c: Allow jit_jmpi on a
- target that is not a node. This may lead to hard to
- debug code generation, but is a required feature for
- certain generators, like the ones that used lightning
- 1.2x. Note that previously, but not really well
- documented, it was instructed to use:
- jit_movi(rn, addr); jit_jmpr(rn);
- but now, plain:
- jit_patch_abs(jit_jmpi(), addr);
- should also work.
-
-2014-09-24 Paulo Andrade <address@hidden>
-
- * lib/jit_x86-sz.c: Generate information about instruction
- lengths for more precise calculation of buffer size on
- Windows x64. This change is specially important because
- the maximum instruction length is larger than other
- systems, what could cause an out of bounds write on
- special conditions without this update.

-
- * check/lightning.c: Add workaround to conflicting global

-
-2014-09-24 Paulo Andrade <address@hidden>
-
- * check/lightning.c: Add a hopefully temporary kludge to not use

-
- * include/lightning/jit_private.h: Use symbolic name for first
- integer register argument, as this is different in sysv and
- win64 abi.
-
- * include/lightning/jit_x86.h: Add conditionals and definitions
- for Windows x64 (under __CYGWIN__ preprocessor conditional).
-
- * lib/jit_x86-cpu.c: Correct one instruction encoding bug, that
- was working by accident. Only use rax to rdx for some byte
- operations to work on compatibility mode (that is, to generate
- the proper encoding, instead of actually generating encoding
- for high byte registers, e.g. %bh).
- Add proper prolog and epilog for windows x64.
-
- * lib/jit_x86-sse.c: Correct a swapped rex prefix for float
- operations.
-
- * lib/jit_x86.c: Adjust to support Windows x64 abi.

- cannot be tracked. This is a rethink of the previous commit,
- and is a better approach, otherwise there would not be much
- sense on relying on jit_callee_save_p if it could not be
- trusted.
-
- * check/jmpr.tst, check/jmpr.ok: New files implementing a very
- simple test case, that would actually cause an assertion on
- code before the change to only mark as live when reaching a
- jump that could not tracked, the actually advertised as callee
- save registers.
-
- check/Makefile.am: Update for new jmpr test case.
-
-2014-09-01 Paulo Andrade <address@hidden>
-
- * lib/lightning.c: Do not mark all registers in unknown state
- as live on jit_jmpr, or jit_jmpi to an absolute address. Instead,
- treat it as a function call, and only consider JIT_Vn registers
- as possibly live.
-

- bitfield for temporary registers that cannot be spilled
- because the reload would be after a conditional jump; the
- patch only adds an extra assertion. These conditions do
- not happen on documented lightning usage, but can happen

-
- * lib/lightning.c: Always mark JIT_RET and JIT_FRET as

- argument, and likely also a null src or dst.
-
-2014-07-27 Paulo Andrade <address@hidden>
-
- * include/lightning/jit_private.h, lib/jit_disasm.c,
- lib/lightning.c: Remove the global jit_progname variable.
- It was being only used in jit_init_debug, that is called
- from init_jit, so, just pass an argument.
-
-2014-07-27 Paulo Andrade <address@hidden>
-
- * doc/body.texi: Add note that jit_set_memory_functions
- should be called before init_jit, because init_jit
- itself may call the memory wrappers.
-
-2014-04-22 Paulo Andrade <address@hidden>
-
- * lib/jit_arm.c: Do not get confused with default settings
- if /proc is not mounted on Linux specific code path.
-
-2014-04-09 Paulo Andrade <address@hidden>
-
- * include/lightning/jit_aarch64.h, include/lightning/jit_arm.h,
- include/lightning/jit_hppa.h, include/lightning/jit_ia64.h,
- include/lightning/jit_mips.h, include/lightning/jit_ppc.h,
- include/lightning/jit_private.h, include/lightning/jit_s390x.h,
- include/lightning/jit_sparc.h, include/lightning/jit_x86.h:
- Do not add jit_regset_t, JIT_RA0, and JIT_FA0 to the installed
- header file. These types and definitions are supposed to be
- only used internally.
-
-2014-04-05 Paulo Andrade <address@hidden>
-
- * lib/jit_arm-cpu.c: Only adjust stack pointer in prolog if
- need stack space, that is, do not emit a nop instruction
- subtracting zero from the stack pointer.
-
-2014-04-04 Paulo Andrade <address@hidden>
-
- * lib/jit_disasm.c: Correct a crash in the doc/printf example
- on arm due to releasing the data_info information in
- jit_clear_state. This is a special case for arm only, and
- actually, only armv5 or older uses the data_info buffer,
- or when forcing arm instruction set mode besides thumb
- available.
-
-2014-12-03 Paulo Andrade <address@hidden>
-
- * doc/body.texi: Write detailed description and examples for
- jit_get_memory_functions, jit_set_memory_functions,
- jit_get_code, jit_set_code, jit_get_data and jit_set_data.
-
-2014-12-03 Paulo Andrade <address@hidden>
-
- * include/lightning.h, include/lightning/jit_private.h,
- lib/lightning.c: Implement the new jit_set_data() interface,
- and the new jit_get_data() helper. Like jit_set_code(),
- jit_realize() should be called before jit_set_data().
- The most common usage should be jit_set_data(JIT_DISABLE_DATA
- | JIT_DISABLE_NOTE), to force synthesize any float/double
- constant in the stack and not generate any debug information.
-
- * lib/jit_note.c: Minor change to debug note generation as
- now it uses an alternate temporary data buffer during constants
- and debug generation to accommodate the possibility of the user
- setting an alternate data buffer.
-
- * lib/jit_hppa-fpu.c, lib/jit_s390x.c, lib/jit_s390x-cpu.c,
- lib/jit_s390x-fpu.c, lib/jit_sparc.c, lib/jit_sparc-fpu.c,
- lib/jit_x86-sse.c, lib/jit_x86-x87.c: Implement jit_set_data.
-
- * lib/jit_hppa-sz.c, lib/jit_sparc-sz.c, lib/jit_x86-sz.c,
- lib/jit_s390x-sz.c: Update for several instructions that now
- have a different maximum length due to jit_set_data.
-
- * lib/jit_mips-fpu.c: Implement jit_set_data, but missing
- validation on n32 and n64 abis (and/or big endian).
-
- * lib/jit_mips-sz.c: Update for changes in o32.
-
- * lib/jit_ppc-fpu.c: Implement jit_set_data, but missing
- validation on Darwin PPC.
-
- * lib/jit_ppc-sz.c: Update for changes in powerpc 32 and
- 64 bit.
-
- * lib/jit_ia64-fpu.c: Implement untested jit_set_data.
-
- * TODO: Add note to list ports that were not tested for the
- new jit_set_data() feature, due to no longer having access
- to them.
-
- * check/nodata.c: New file implementing a simple test exercising
- several different conditions created by jit_set_data().
-
- * check/check.nodata.sh: New file implementing a wrapper
- over the existing *.tst files, that runs all tests without
- using a data buffer for constants; only meaningful (and
- enabled) on architectures that used to store float/double
- constants on a read only data buffer.
-
- * configure.ac, check/Makefile.am: Update for the new test
- cases.
-
- * check/lightning.c: Implement the new "-d" option that
- sets an internal flag to call jit_set_data() disable
- constants and debug, that is, using only a pure code
- buffer.
-
-2014-11-03 Paulo Andrade <address@hidden>
-
- * include/lightning.h, include/lightning/jit_private.h,
- lib/lightning.c: Implement the new jit_set_code() interface,
- that allows instructing lightning to use an alternate code
- buffer. The new jit_realize() function should be called
- before jit_set_code(), and usually call jit_get_code()
- to query the amount of bytes expected to be required for
- the code.
-
- * lib/jit_size.c: Minor update to have less chances of
- miscalculating the code buffer by starting the counter
- with the size of the longest instruction instead of zero,
- as code emit fails if at any moment less than the longest
- instruction bytes are available.
-
- * check/setcode.c: New file implementing some basic tests
- of the new jit_set_code() interface.
-
- * check/Makefile.am: Update for newer test case.
-
-2014-06-03 Paulo Andrade <address@hidden>
-
- * include/lightning.h, lib/lightning.c: Add the new
- jit_indirect() call, that returns a special label node,
- and tells lightning that the label may be the target of
- an indirect jump.
-
- * doc/body.texi: Document the new jit_indirect() call, and
- add examples of different ways to create labels and branches.
-
-2014-23-02 Paulo Andrade <address@hidden>
-
- * lib/jit_x86.c: Rewrite previous patch to inline save/restore
- because clobbering %ebx in x86 is treated as an error
- (jit_x86.c:239:5: error: PIC register clobbered by 'ebx' in 'asm').
-
-2014-19-02 Paulo Andrade <address@hidden>
-
- * lib/jit_x86.c: Rewrite incorrect inline assembly that could
- truncate a variable in a callee save register. Now it simply
- tells gcc that the register is clobbered, instead of using a
- *32 bit* swap with a temporary variable. The problem only
- happens when compiling with optimization.
-
-2014-19-02 Paulo Andrade <address@hidden>
-
- * include/lightning/jit_aarch64.h, include/lightning/jit_arm.h,

- include/lightning/jit_mips.h, include/lightning/jit_ppc.h,
- include/lightning/jit_s390x.h, include/lightning/jit_sparc.h,
- include/lightning/jit_x86.h: Change jit_regset_t to an
- unsigned type, to allow safe right shift.
-
- * lib/lightning.c: Rewrite jit_regset_scan1 to allow easier
- compiler optimization.
-
-2013-12-03 Paulo Andrade <address@hidden>
-
- * lib/jit_x86-x87.c: Correct wrong optimization when
- loading the log(2) constant.
-
-2013-12-03 Paulo Andrade <address@hidden>
-
- * lib/jit_x86-cpu.c: Use the emms instruction before
- calling any function. This is particularly important
- when using c99 complex functions as it can easily
- overflow the x87 stack due to the way lightning uses
- the x87 stack as a flat register file.
-
-2013-12-02 Paulo Andrade <address@hidden>
-
- * lib/jit_x86-x87.c: Correct wrong code generation due
- to comparing the base and not the value register with
- %st(0) in stxi_f.
-
-2013-12-02 Paulo Andrade <address@hidden>
-
- * lib/jit_x86-x87.c, lib/jit_x86.c: Use 8 bytes aligned
- stack offset for float/double x87 to/from sse move.
-
-2013-11-27 Paulo Andrade <address@hidden>
-
- * configure.ac, lib/jit_arm-swf.c, lib/jit_arm.c: Add
- changes that should at least allow building lightning
- on Apple iOS7.
-
-2013-10-08 Paulo Andrade <address@hidden>
-
- * lib/jit_ppc-cpu.c: Correct wrong shortcut for ldxi_l with
- a zero offset, that was calling ldr_i instead of ldr_l.
-
-2013-10-08 Paulo Andrade <address@hidden>
-
- * include/lightning/jit_arm.h, lib/jit_arm-cpu.c: Do not use
- by default load/store instructions that map to ldrt/strt.
- There is already the long displacement version for positive
- offsets, and when using a (shorter) negative offset it does
- not map to ldrt/strt. At least on qemu strt may cause
- reproducible, but unexpected SIGILL.
-
-2013-10-08 Paulo Andrade <address@hidden>
-
- * lib/jit_arm-vfp.c: Correct wrong load/store offset
- calculation when the displacement is constant but too
- large to use an instruction with an immediate offset.
-
-2013-10-07 Paulo Andrade <address@hidden>
-
- * check/self.c: Extend tests to validate jit_callee_save_p
- does not cause an assertion on valid arguments, and test
- extra registers defined on some backends.
-
- * configure.ac: Do not ignore environment CFLAGS when
- checking if need to test runtime configurable options,
- like use x87 when sse2 is available, arm instruction set
- instead of thumb, etc.
-
- * include/lightning/jit_arm.h: Correct wrong jit_f macro
- definition.
-
- * include/lightning/jit_ia64.h, include/lightning/jit_ppc.h:
- Correct wrong jit_r macro definition.
-
- * lib/jit_x86-x87.c, lib/jit_x86.c: Actually use the
- reserved stack space for integer to/from float conversion.
- The stack space was also changed to ensure it is 8 bytes
- aligned. Also, for Solaris x86 in 32 bit mode, an alternate
- truncr_d was implemented because for some reason it is
- failing with SIGILL if using the "fisttpl" instructions,
- that must be available on p6 or newer, but for the sake of
- making all tests pass, implement a 486 or newer sequence
- if "sun" is defined.
-
-2013-10-03 Paulo Andrade <address@hidden>
-
- * include/lightning/jit_mips.h, lib/jit_mips-cpu.c,
- lib/jit_mips-sz.c, lib/jit_mips.c, size: Build and
- pass all test cases on Irix big endian mips using
- the 64 bit abi.
-
-2013-10-02 Paulo Andrade <address@hidden>
-
- * include/lightning/jit_mips.h: Add proper mips abi detection.
-
-2013-09-30 Paulo Andrade <address@hidden>
-
- * lib/jit_print.c: Do not crash if calling jit_print from
- gdb before actually emitting code.
-
- * lib/lightning.c: Correct misplaced check for already
- visited blocks on conditional branches, what was preventing
- proper merge live bit masks of forward blocks.
-
-2013-09-30 Paulo Andrade <address@hidden>
-
- * lib/jit_x86-cpu.c: Correct not properly tested case of using
- %r12 as index register, what was causing an invalid assertion.
- %r12 is mapped to the "extra" JIT_R3 register, and test cases
- only test "standard" lightning registers.
-
-2013-09-28 Paulo Andrade <address@hidden>
-
- * lib/jit_ia64.c: Minor change to force collecting the maximum
- instruction length in the --enable-devel-get-jit-size build
- mode. The actual generated file did not change because the
- sampling was large enough that it had already collected proper
- information in the previously slightly buggy code (not forcing
- a sync of the instructions that could be combined).
-
-2013-09-27 Paulo Andrade <address@hidden>
-
- * lib/jit_arm.c: Correct build when disassembler is
- disabled.
-
-2013-09-25 Paulo Andrade <address@hidden>
-
- * lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c: Correct some
- off by one range checks (that were only accepting values
- one less than the maximum allowed) and an invalid test
- condition check that was forcing it to always use
- indirect jumps even when reachable with an immediate
- displacement.
-
-2013-09-24 Paulo Andrade <address@hidden>

- lib/jit_s390x-sz.c, lib/jit_size.c, lib/jit_sparc-sz.c,
- lib/jit_x86-sz.c: New files implementing static tables
- with longest known instructions length generated to match
- a lightning instruction. These tables should make it easier
- to make it very unlikely to ever miscalculate, or by too
- much, the size of a code buffer.
-
- * lib/jit_size.c: New file that aids to either collect
- jit code size information, or use the information depending
- on build options.
-
- * size.c: New helper file that parses input for, and create
- an initial jit_$arch-sz.c file, that needs some minor edit
- for arches with multiple configurations.
-
- * configure.ac, Makefile.am: Add the new, devel mode only
- --enable-devel-get-jit-size configure option, that sets
- compile time flags to collect jit code size information,
- that will be used as input for the "noinst size program".
-
- * lib/jit_aarch64.c, lib/jit_arm.c, lib/jit_disasm.c,
- lib/jit_hppa.c, lib/jit_ia64.c, lib/jit_memory.c,
- lib/jit_mips.c, lib/jit_ppc.c, lib/jit_s390x.c,
- lib/jit_sparc.c, lib/jit_x86.c, lib/lightning.c: Minor
- changes for the --enable-devel-get-jit-size build mode,
- as well as the "production build mode" with jit code
- size information.
-
-2013-09-14 Paulo Andrade <address@hidden>
-
- * include/lightning.h, lib/lightning.c: Add the new
- jit_pointer_p interface, that returns a boolean value
- telling if the pointer argument is inside the jit
- code buffer. This is useful to avoid the need to add
- extra labels and calls to jit_address to figure bounds
- of code buffer, and still keep internal data private.
-
-2013-09-13 Paulo Andrade <address@hidden>
-
- * include/lightning.h, include/lightning/jit_private.h,
- lib/jit_note.c: Change the code argument of jit_get_note
- to a jit_pointer_t and make jit_get_note a public interface.
- It was intended so since start, as a way to map an offset
- in the code to a function name, file name and line number
- mapping.
-
-2013-09-11 Paulo Andrade <address@hidden>
-
- * doc/body.texi: Correct reversed arguments in example of
- usage in a (possibly) multi threaded, multiple jit_state_t
- environments.
-
- * include/lightning/jit_arm.h, include/lightning/jit_private.h,
- lib/jit_arm-cpu.c, lib/jit_arm.c: Make a previously, non
- documented, global state private to the related jit_state_t
- generating code.
-
-2013-09-10 Paulo Andrade <address@hidden>
-
- * check/self.c, check/self.ok: New files implementing simple
- consistency check assertions. At first validating some macros
- that use values from different sources agree.
-
- * check/Makefile.am: Update for the new test case.
-
- * include/lightning.h, lib/lightning.c: Add the new
- jit_callee_save_p() call, that is intended to be used when
- writing complex code using lightning, so that one does not
- need to verify what backend is being used, or have access to
- private data, to query if a register is callee save or not;
- on several backends the scratch registers are actually callee
- save.
-
- * include/lightning/jit_aarch64.h, include/lightning/jit_arm.h,
- include/lightning/jit_hppa.h, include/lightning/jit_mips.h,
- include/lightning/jit_ppc.h, include/lightning/jit_sparc.h,
- include/lightning/jit_x86.h: Add an explicit definition for
- JIT_R3-JIT_Rn, JIT_V3-JIT_Vn and JIT_F6-JIT_Fn when applicable.
- This allows one to write code based on "#if defined(JIT_XN)"
- and therefore, not need to check what is the current backend
- or have access to private data structures. This is particularly
- useful when writing virtual machines with several specialized,
- global registers.
-
- * lib/jit_ia64.c: Properly flag the callee save general
- purpose registers as such, so that jit_callee_save_p() works
- as intended.
-
-2013-09-10 Paulo Andrade <address@hidden>
-
- * check/lightning.c, configure.ac: Conditionally use the
- code written to workaround a bug in the Hercules emulator,
- as isnan and isinf are not available at least on HP-UX ia64.
-
-2013-09-10 Paulo Andrade <address@hidden>
-
- * lib/jit_s390x-cpu.c: Spill/reload correct callee save
- float registers.
-
-2013-09-10 Paulo Andrade <address@hidden>
-
- * lib/jit_hppa-cpu.c: Correct code to call a function stored
- in a register or a patched function address.
-
-2013-09-10 Paulo Andrade <address@hidden>
-
- * lib/jit_ia64-cpu.c: Correct incorrect logic when restoring
- the value of the "r2" callee save register.
-
-2013-08-29 Paulo Andrade <address@hidden>
-
- * lib/jit_arm-cpu.c, lib/jit_arm.c: Correct wrong test and update
- of the thumb offset information, when checking if needing to
- patch a jump from arm to thumb mode. The problem would happen when
- remapping the code buffer, and the new address being lower than
- the previous one.
-
-2013-08-26 Paulo Andrade <address@hidden>
-
- * configure.ac: Extend FreeBSD test to also handle NetBSD.
-
- * lib/jit_x86-cpu.c: Correct wrongly defined offset type of
- ldxi_ui. Problem detected when building on NetBSD.
-
- * lib/lightning.c: Adjust code to handle NetBSD mremap,
- where arguments do not match Linux mremap.
-
-2013-08-26 Paulo Andrade <address@hidden>
-
- * lib/jit_ppc.c: Correct C sequence point problem miscalculating
- the actual function address in a function descriptor. Problem
- happens with gcc 4.8.1 at least.
-
-2013-08-11 Paulo Andrade <address@hidden>
-
- * lib/jit_s390x-cpu.c: Correct code checking if immediate
- fits instruction, but using the negated value.
-
-2013-07-28 Paulo Andrade <address@hidden>
-
- * include/lightning/jit_s390x.h, lib/jit_s390x-cpu.c,
- lib/jit_s390x-fpu.c, lib/jit_s390x.c: New files
- implementing the new s390x port.
-
- * configure.ac, include/lightning.h,
- include/lightning/Makefile.am,
- include/lightning/jit_private.h,
- lib/Makefile.am, lib/jit_disasm.c, lib/lightning.c:
- Minor adaptation for the new s390x backend.
-
- * check/float.tst: Update for the s390x result of
- truncating +Inf to integer.
-
- * check/qalu_mul.tst: Add extra test cases to better test
- high word of signed multiplication as the result is
- adjust from unsigned multiplication on s390x.
-
-2013-07-28 Paulo Andrade <address@hidden>
-
- * check/lightning.c: Do not assume casting a double NaN or
- Inf to float will produce the expected float NaN or Inf.
- This is not true at least under s390x.
-
-2013-07-28 Paulo Andrade <address@hidden>
-
- * check/check.arm.sh, check/check.sh, check/check.swf.sh,
- check/check.x87.sh: Properly check test programs output,
- not just rely on the test program self testing the results
- and not crashing.
-
-2013-07-28 Paulo Andrade <address@hidden>
-
- * lib/jit_aarch64.c: Remove unused macros left from cut&paste
- of jit_arm.c.
-
-2013-07-16 Paulo Andrade <address@hidden>
-
- * include/lightning/jit_aarch64.h, lib/jit_aarch64-cpu.c,
- lib/jit_aarch64-fpu.c, lib/jit_aarch64.c: New files
- implementing the new aarch64 port, as a new architecture,
- not as an expansion of the existing armv[4-7] port.
-
- * check/lightning.c: Add aarch64 support and a small
- change to recognize character constants as immediate
- values.
-
- * check/float.tst: Add aarch64 preprocessor conditionals
- to select proper expected value when converting [+-]Inf
- and NaN to integer.
-
- * include/lightning/jit_arm.h, lib/jit_arm.c: Minor changes
- to better match the new aarch64 files.
-
- * configure.ac, include/lightning.h,
- include/lightning/Makefile.am, include/lightning/jit_private.h,
- lib/Makefile.am, lib/lightning.c: Minor adjustments
- for the aarch64 port.
-
-2013-07-08 Paulo Andrade <address@hidden>
-
- * NEWS, THANKS, configure.ac, doc/version.texi: Update for
- the 1.99a second alpha release.
-
-2013-06-25 Paulo Andrade <address@hidden>
-
- * lib/jit_mips.c: Correct cut&paste error that caused wrong
- stack offset calculation for double arguments in stack in
- the o32 abi.
- Correct typo in the __LITTLE_ENDIAN macro name, that came
- from cut&paste error in the original typo in lib/jit_ppc.c.
-
- * lib/jit_ia64.c, lib/jit_ppc.c: Correct typo in the
- __LITTLE_ENDIAN macro name.
-
-2013-06-22 Paulo Andrade <address@hidden>
-
- * check/lightning.c, configure.ac, include/lightning.h,
- lib/lightning.c: Add tests and quirks to build/detect
- and/or work on Irix.
-
- * include/lightning/jit_mips.h, lib/jit_mips-cpu.c,
- lib/jit_mips-fpu.c, lib/jit_mips.c: Adapt code to run
- in big endian mips, using the n32 abi.
-
-2013-06-18 Paulo Andrade <address@hidden>
-
- * include/lightning.h: Minor extra preprocessor testing
- to "detect" byte order on x86 solaris, that now builds
- and pass all test cases.
-
-2013-06-18 Paulo Andrade <address@hidden>
-
- * lib/jit_sparc-cpu.c: Correct compiler warning of value
- used before assignment. The usage is bogus as the api
- requires always patching jumps, but the random value used
- could cause an assertion due to invalid displacement.
-
- * lib/jit_sparc.c: Always load and store double arguments
- in stack as 2 float loads or stores, for safety, as unaligned
- access is not allowed in Sparc Solaris.
-
-2013-06-14 Paulo Andrade <address@hidden>
-
- * configure.ac: Force -mlp64 to CFLAGS on HP-UX ia64 port.
- It is the only supported mode, and expects gcc as C compiler.
-
- * include/lightning.h, lib/jit_ia64-cpu.c, lib/jit_ia64.c:
- Correct ia64 port to work on HP-UX that runs it in big endian
- mode.
-
-2013-06-10 Paulo Andrade <address@hidden>
-
- * lib/jit_hppa.c: Sanitize the cache synchronization inline
- assembly code that was doing twice the work and redundantly
- flushing the end address every loop iteration.
-
-2013-06-09 Paulo Andrade <address@hidden>
-
- * configure.ac, check/Makefile.am, doc/Makefile.am: Do not
- explicitly link to -ldl, but instead autodetect the library
- with dlopen, dlsym, etc.
-
- * check/lightning.c: Add workaround to apparently buggy
- getopt in HP-UX that sets optind to the wrong index, and
- use RTLD_NEXT on HP-UX instead of RTLD_DEFAULT to dlsym
- global symbols.
-
- * include/lightning.h: Rework definitions of wordsize and
- byte order to detect proper values on HP-UX.
-
- * lib/lightning.c: Minor correction to use MAP_ANONYMOUS
- instead of MAP_ANON on HP-UX.
-
- * lib/jit_hppa.c: Float arguments must be passed on integer
- registers on HP-UX, not only for varargs functions.
- Add code to properly clear instruction cache. This was
- not required on Debian hppa port, but may have been working
- by accident.
-
- * lib/jit_hppa-cpu.c: Follow pattern of HP-UX binaries and
- use bve,n instead of bv,n to return from functions.
-
- * lib/jit_hppa-fpu.c: For some reason "fst? frX,rX,(rY)" did
- not work on the tested computer (HP-UX B.11.23 U 9000/785 HP-UX)
- so the code was changed, at first for __hpux only to add the
- base and offset register and use the instruction with an
- immediate (zero) offset.
-
-2013-06-07 Paulo Andrade <address@hidden>
-
- * check/lightning.c, lib/jit_disasm.c, lib/jit_ppc-cpu.c,
- lib/jit_ppc-fpu.c, lib/jit_ppc.c, include/lightning.h,
- include/lightning/jit_ppc.h, include/lightning/jit_private.h:
- Adapt code to work on 32 bit AIX ppc using gcc. Most changes
- are basically to adapt the elf64 logic to 32 bit, as it does
- not use the same convention of 32 bit Darwin ppc.
-
- * check/stack.tst: Add a fake memcpy function to the test
- case if running under AIX, as it is not available to dlsym.
-
- * configure.ac: Check for getopt.h header, not available in
- AIX.

-
- * include/lightning/jit_hppa.h, lib/jit_hppa-cpu.c,
- lib/jit_hppa-fpu.c, lib/jit_hppa.c: New files implementing
- the hppa port. Built on Debian Linux PA-RISC 2.0, 32 bit.
-
- * check/float.tst: Add preprocessor for hppa expected
- values when converting NaN and +-Inf to an integer.
-
- * check/ldst.inc: Ensure double load/store tests use an
- 8 byte aligned address by default.
-
- * lib/lightning.c: Correct a bug found during tests in
- the new port, where qmul* and qdiv* were not properly
- setting one of the result registers as modified in the
- function, what would be a problem if the only "write"
- usage were the qmul* or qdiv*.
-
- * check/varargs.tst, check/varargs.ok: Add one extra
- interleaved integer/double test to validate proper code
- generation in the extra case.
-
- * check/lightning.c, configure.ac, include/lightning.h,
- include/lightning/Makefile.am,
- include/lightning/jit_private.h, lib/Makefile.am,
- lib/jit_disasm.c: Update for the hppa port.
-
-2013-04-27 Paulo Andrade <address@hidden>
-
- * check/varargs.tst: Correct misplaced .align directive
- that was causing the double buffer to not be aligned at
- 8 bytes.
- * lib/jit_ia64-cpu.c:
- Properly implement abi for excess arguments passed on
- stack.
- Simplify load/store with immediate displacement argument
- with zero value.
- Simplify some calls to "subi" changing to "addi" with
- a negative argument.
- Remove some #if 0'ed code, that could be useful in
- special conditions, but the most useful one would be
- to "optimize" "static" jit functions, but for the sake
- of simplicity, jit functions are implemented in a way
- that can be passed back to C code as C function pointers.
- Add an attribute to prototypes of several unused functions.
- These functions are defined for the sake of implementing all
- Itanium documented instructions, but a significant amount of
- them is not used by lightning.
- * lib/jit_ia64-fpu.c: Simplify load/store with zero immediate
- displacement and add unused attribute for functions not used
- by lightning, but required to provide macros implementing all
- Itanium documented instructions.
- * lib/jit_ia64.c: Update for the properly implemented abi
- for stack arguments.
- * lib/lightning.c: Mark an unused function as such.
-
-2013-04-27 Paulo Andrade <address@hidden>
-
- lib/jit_ia64-cpu.c:
- Correct immediate range check of integer comparisons when
- inverting arguments.
- Correct gei_u that was not decrementing immediate when
- inverting arguments.
- Correct b?add* and b?sub* that were not properly updating
- the result register.
-
-2013-04-27 Paulo Andrade <address@hidden>
-
- * lib/jit_ia64-cpu.c: Correct wrong mapping of 2 instructions
- in "M-, stop, M-, stop" translation, that was ignoring the
- last stop (implemented as a nop I- stop).
-
- * lib/jit_ia64-fpu.c: Properly implement fnorm.s and fnorm.d,
- as well as the proper integer to float or double conversion.
-
-2013-04-27 Paulo Andrade <address@hidden>
-
- * lib/jit_ia64-cpu.c: Correct bogus implementation of ldr_T
- for signed integers, that was using ld1.s, ld2.s and ld4.s.
- The ".s" stands for speculative load, not sign extend.
-
- * lib/jit_ia64-fpu.c: Correct bogus implementation of ldxr_T
- for float and double. The third (actually, second) argument
- is indeed added to the base register, but the base register
- is modified. The actual M7 implementation was already correct,
- just the ldxr_f and ldxr_d implementation that was kept in
- a prototype state, misinterpreting what M7 does.
-
-2013-04-27 Paulo Andrade <address@hidden>
-
- * lib/jit_ia64-cpu.c: Correct X2 pattern matching by preventing
- it to attempt to require a stop between the L and the X
- instruction; that is, check the registers and predicates
- before emitting the L instruction, not after.
-
- * lib/jit_ia64-fpu.c: Slightly simplify and correct
- divr_f and divrd_d implementation.
-
- * check/lightning.c: Add __ia64__ preprocessor define
- on Itanium.
-
- * check/alu.inc, check/clobber.tst, check/float.tst: Define
- several macros conditionally to __ia64__. This is required
- because __ia64__ jit generation can use way too many memory,
- due to not implementing instruction reordering to avoid
- as much as possible "stops", what causes way too many nops
- to be generated, as well as the fact that division and
- remainder requires function calls, and float division
- requires significant code to implement.
-
-2013-04-27 Paulo Andrade <address@hidden>
-
- * include/lightning.h: Add new backend specific movr_w_d,
- movr_d_w and movi_d_w codes as helpers to ia64 varargs
- functions arguments.
-
- * lib/jit_ia64-cpu.c:
- Correct wrong encoding of A5 small integers.
- Correct define of "mux" instruction modifiers.
- Correct ordering of arguments and predicates of cmp_xy
- implementation with immediate arguments; like most other
- codes with an immediate, the immediate is the second, not
- the third argument.
-
- * lib/jit_ia64-fpu.c: Actual implementation of the code
- to move to/from gpr to/from fpr, to implement varargs abi.
-
- * lib/jit_ia64.c: Make fpr argument registers not allocatable
- as temporaries, no need for the extra checks when there are
- plenty registers.
-
- * lib/jit_print.c, lib/lightning.c: Minor updates for the
- new movr_w_d, movr_d_w and movi_d_w codes.
-
-2013-04-26 Paulo Andrade <address@hidden>
-
- * lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c: Correct code to
- also insert a stop to break an instruction group if a
- register is written more than once in the same group.
- This may happen if a register is argument and result of
- some lightning call (not a real instruction). The most
- common case should be code in the pattern:
- movl rn=largenum
- ...
- mov rn=smallnum
- where "rn" would end up holding "largenum".
- But the problem possibly could happen in other circumstances.

-2013-04-26 Paulo Andrade <address@hidden>
-
- * include/lightning/jit_ia64.h, lib/jit_ia64-cpu.c,
- lib/jit_ia64-fpu.c, lib/jit_ia64.c:
- Relocate JIT_Rn registers to the local registers, as, like
- float registers, div/rem and sqrt are implemented as function
- calls, and may overwrite non saved scratch registers.
- Change patch_at to receive a jit_code_t instead of a
- jit_node_t, so that it is easier to "inline" patches when
- some instruction requires complex code to implement, e.g.
- uneq and ltgt.
- Correct arguments to FMA and FMA like instructions that,
- due to a cut&paste error were passing the wrong argument
- to the related F- implementation function.
- Rewrite ltgt to return the proper result if one (or both)
- of the arguments is unordered.

- * include/lightning/jit_ia64.h, include/lightning/jit_private.h,
- lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c, lib/jit_ia64.c,
- lib/lightning.c: Rework code to detect need of a "stop" to
- also handle predicates, as if a predicate is written, it
- cannot be read in the same instruction group.
- Use a single jit_regset_t variable for all registers when
- checking need for a stop (increment value by 128 for
- float registers).
- Correct wrong "subi" implementation, as the code executed
- is r0=im-r1, not r0=r1-im.
- Use standard lightning 6 fpr registers, and rework to
- use callee save float registers, that may be spill/reloaded
- in prolog/epilog. This is required because some jit
- instructions implementations need to call functions; currently
- integer div/mod and float sqrt, what may change the value of
- scratch float registers.
- Rework point of "sync" of branches that need to return a
- patch'able address, because the need for a "stop" before a
- predicate read causes all branches to be the instruction
- in slot 0, as there is no template to "stop" and branch
- in the same instruction "bundle".

-2013-04-25 Paulo Andrade <address@hidden>
-
- * include/lightning/jit_ia64.h, lib/jit_ia64-cpu.c,
- lib/jit_ia64-fpu.c, lib/jit_ia64.c: New files implementing
- the basic infrastructure of an Itanium port. The code
- compiles and can generate jit for basic hello world like
- functions.
-
- * check/lightning.c, configure.ac, include/lightning.h,
- include/lightning/Makefile.am, include/lightning/jit_private.h,
- lib/Makefile.am, lib/lightning.c: Update for the Itanium
- port.
-
- * lib/jit_mips-cpu.c, lib/jit_mips.c: Correct typo and
- make the jit_carry register local to the jit_state_t.
- This matches code reviewed in the Itanium port, that
- should use the same base logic to handle carry/borrow.

- lib/jit_sparc.c, lib/jit_x86-cpu.c, lib/jit_x86.c,
- lib/lightning.c: Change all jit_regset macros to take
- a pointer argument, to avoid structure copies when
- adding a port to an architecture with more than 64
- registers.
-
-2013-04-08 Paulo Andrade <address@hidden>
-
- * lib/jit_arm.c, lib/jit_ppc.c: Do not rely on __clear_cache
- aligning to the next page boundary the end argument. It may
- actually truncate it.
-
-2013-03-29 Paulo Andrade <address@hidden>
-
- * include/lightning/jit_private.h, lib/jit_arm.c, lib/jit_memory.c,
- lib/jit_mips.c, lib/jit_ppc.c, lib/jit_sparc.c, lib/jit_x86.c,
- lib/lightning.c: Do not start over jit generation if can grow
- the code buffer with mremap without moving the base pointer.
-
-2013-03-29 Paulo Andrade <address@hidden>
-
- * lib/jit_memory.c: Implement a simple memory allocation wrapper
- to allow overriding calls to malloc/calloc/realloc/free, as well
- as ensuring all memory containing pointers is zero or points to
- allocated memory.
-
- * include/lightning.h, include/lightning/jit_private.h: Definitions
- for the memory allocation wrapper.
-
- * lib/Makefile.am: Update for new jit_memory.c file.
-
- * lib/jit_arm.c, lib/jit_disasm.c, lib/jit_mips.c, lib/jit_note.c,
- lib/jit_ppc.c, lib/jit_sparc.c, lib/jit_x86.c, lib/lightning.c:
- Use the new memory allocation wrapper code.
-
-2013-03-22 Paulo Andrade <address@hidden>
-
- * configure.ac, include/lightning/jit_private.h, lib/lightning.c:
- Remove dependency on gmp. Only a simple bitmap was required, and
- that was not enough reason to force linking to gmp and possible
- complications caused by it.
-
-2013-03-10 Paulo Andrade <address@hidden>
-
- * include/lightning.h: Add check for __powerpc__ defined
- in Linux, while Darwin defines __ppc__.
-
- * include/lightning/jit_ppc.h: Adjust register definitions
- for Darwin 32 bit and Linux 64 bit ppc usage and/or ABI.
-
- * include/lightning/jit_private.h: Add proper check for
- Linux __powerpc__ and an data definition for an workaround
- to properly handle code that starts with a jump to a "main"
- label.
-
- * lib/jit_disasm.c: Add extra disassembler initialization
- for __powerpc64__.
-
- * lib/jit_ppc-cpu.c: Add extra macros and functions, and
- correct/adapt previous ones to handle powerpc64.
-
- * lib/jit_ppc-fpu.c: Adapt for 64 bit wordsize. Basically
- add conversion from/to int32/int64 and proper handling of
- load/store offsets too large for 32 bit.
-
- * lib/jit_ppc.c: Add calls to 64 bit codes and adaptation
- for the PowerPC 64 bit Linux ABI.
-
- * lib/jit_arm.c, lib/jit_mips.c, lib/jit_sparc, lib/jit_x86.c,
- lib/lightning.c: Correct off by one error when restarting jit
- of a function due to finding too late that needs to spill/reload
- some register. Problem was found by accident on a very special
- condition during PowerPC 64 code adaptation.
-
-2013-03-08 Paulo Andrade <address@hidden>
-
- * check/lightning.c: Add missing ppc preprocessor definition.
-
-2013-03-06 Paulo Andrade <address@hidden>
-
- * check/float.tst: Comment out the int to negative infinity
- test in mips for the moment because not all Loongson agrees
- on the result.
-
- * lib/jit_disasm.c: Add a test instead of an assertion
- when loading symbols for disassembly due to a failure with
- a simple binutils build in Debian mipsel64.

- easier to understand what data is available during
- jit runtime.
-
-2013-03-06 Paulo Andrade <address@hidden>
-
- * lib/lightning.c: Make data and code buffer readonly.
-
-2013-02-20 Paulo Andrade <address@hidden>
-
- * doc/body.texi: Fool proof validate the examples of what
- an assembly-language programmer would write and correct the
- wrong sparc example.
-
-2013-02-19 Paulo Andrade <address@hidden>
-
- * doc/body.texi: Add back the SPARC code generation example.
-
-2013-02-19 Paulo Andrade <address@hidden>
-
- * check/lightning.c: Remove state flag to work with partial
- sparc port, by just disassembling if there was incomplete
- code generation.
-
- * jit_sparc-cpu.c: Correct wrong range check for immediate
- integer constants (off by one bit shift).
- Correct macro implementing equivalent "rd %y, rd" assembly.
- Implement qmul* and qdiv*.
-
- * jit_sparc.c: Update for qmul* and qdiv* and remove logic
- to handle incomplete code generation during sparc port.
-
-2013-02-18 Paulo Andrade <address@hidden>
-
- * check/float.tst: Add sparc to list of known NaN and +-Inf
- to integer conversion.
-
- * check/lightning.c: Define __sparc__ to preprocessor in
- the sparc backend.
-
- * include/lightning/jit_private.h: Correct wrong definition
- of emit_stxi_d, that has lived for a long time, but would
- cause problems whenever needing to spill/reload a float
- register.
-
- * include/lightning/jit_sparc.h: Can only use %g2,%g3,%g4
- for scratch variables, as other "global" registers are
- reserved for the system, e.g. libc.
- Reorder float register naming to make it easier to
- access odd float registers, so that generating code for
- pusharg and getarg is easier for the IR.
-
- * lib/jit_mips-cpu.c, lib/jit_ppc-cpu.c: Update to match
- new code in jit_sparc-cpu.c. It must call jit_get_reg
- with jit_class_nospill if using the register to move
- an unconditional branch address to it, as the reload
- will not happen (actually could happen in the delay
- slot...)
-
- * lib/jit_sparc-cpu.c: Correct wrong macro definition for
- ldxr_s.
- Properly implement div* and implement rem. Div* needs
- to use the y register, and rem* needs to be synthesized.
- Correct b?sub* macro definitions.
-
- * lib/jit_sparc-fpu.c: Correct reversed float to/from double
- conversion.
- Correct wrong jit_get_reg call asking for a gpr and then
- using the fpr with that number.
- Correct wrong branch displacement computation for
- conditional branches.
-
- * lib/jit_sparc.c: Correct getarg_d and pushargi_d implementation.
- Add rem* entries to the switch converting IR to machine code.
-
- * lib/lightning.c: Correct a problem detected when adding
- the jit_class_nospill flag to jit_get_reg, that was caused
- when having a branch to an "epilog" node, what would cause
- the code to think all registers in unknown state were live,
- while in truth, all registers in unknown state in the
- "just after return" point are actually dead.

-
- * include/lightning/jit_sparc.h, lib/jit_sparc-cpu.c,
- lib/jit_sparc-fpu.c, lib/jit_sparc.c: New files implementing
- the basic framework of the sparc port.
-
- * configure.ac, include/lightning.h, include/lightning/Makefile.am,
- include/lightning/jit_private.h, lib/jit_disasm.c: Update
- for the sparc port framework.
-
- * lib/jit_mips.c: Correct reversed retr/reti logic.
-
- * lib/jit_ppc.c: Correct misspelled __LITTLE_ENDIAN.
-
- * lib/lightning.c: Always do byte hashing in hash_data, because
- the logic to "compress" strings causes large pointers to not
- be guaranteed aligned at 4 byte boundaries.
- Update for the sparc port framework.
-
-2013-02-11 Paulo Andrade <address@hidden>
-
- * lib/jit_arm.c: Correct jit_pushargi_f in the arm hardfp abi.
- Most of the logic uses even numbered register numbers, so that
- a float and a double can be used in the same register, but
- the abi requires packing the float arguments, so jit_pushargi_f
- needs to allocate a temporary register to modify only the
- proper register argument (or be very smart to push two
- immediate arguments if applicable).
-
-2013-02-11 Paulo Andrade <address@hidden>
-
- * include/lightning.h, lib/lightning.c: Implement the new
- jit_clear_state and jit_destroy_state calls. jit_clear_state
- releases all memory not required during jit_execution; that
- is, leaves only the mmap'ed data and code buffers allocated.
- jit_destroy_state releases the mmap'ed buffers as well as
- the jit_state_t object itself, that holds pointers to the
- code and data buffers, as well as annotation pointers (for
- disassembly or backtrace) in the data buffer.
-
- * lib/jit_note.c: Correct invalid vector offset access.
-
- * check/ccall.c, check/lightning.c, doc/ifib.c, doc/incr.c,
- doc/printf.c, doc/rfib.c, doc/rpn.c: Use the new jit_clear_state
- and jit_destroy_state calls, to demonstrate the new code to
- release all jit memory.
-
- * doc/body.texi: Add basic documentation and usage description
- of jit_clear_state and jit_destroy_state.
-
-2013-02-11 Paulo Andrade <address@hidden>
-
- * include/lightning/jit_private.h, lib/jit_note.c, lib/lightning.c:
- Store all annotation information in the mmap'ed area reserved for
- read only data. This adds code to not allocate memory for jit_note_t
- objects, and to relocate jit_line_t objects and its contents after
- calculating annotation information. The jit_line_t objects are
- relocated because it is not possible to always calculate before
- hand data layout because note information may be extended or
- redundant entries removed, as well as allowed to be added in
- non sequential order.
- A bug was also corrected in _jit_set_note, that was causing it
- to allocate new jit_line_t objects when not needed. It was still
- working correctly, but allocating way more memory than required.
-
-2013-02-05 Paulo Andrade <address@hidden>
-
- *include/lightning.h, lib/lightning.c: Add the new jit_live code
- to explicitly mark a register as live. It is required to avoid
- assuming functions always return a value in the gpr and fpr return
- register, and to avoid the need of some very specialized codes
- that vary too much from backend to backend, to instruct the
- optimization code the return register is live.
-
- * lib/jit_arm.c, lib/jit_mips.c, lib/jit_ppc.c, lib/jit_print.c,
- lib/jit_x86.c: Update for the new jit_live code.
-
- * check/ret.ok, check/ret.tst: New files implementing a simple
- test case that would previously fail at least in ix86/x86_64.
-
- * check/Makefile.am: Update for new "ret" test case.
-
-2013-02-05 Paulo Andrade <address@hidden>
-
- * lib/jit_ppc-cpu.c, lib/jit_ppc.c: Validate and correct

- lib/jit_mips.c, lib/jit_ppc-cpu.c, lib/jit_ppc.c,
- lib/jit_x86-cpu.c, lib/jit_x86.c, lib/lightning.c:
- Implement the new qmul and qdiv instructions that return signed
- and unsigned lo/hi multiplication result and div/rem division result.
- These should be useful for jit translation of code that needs to
- know if a multiplication overflows (no branch opcode added) or if
- a division is exact (easy check if remainder is zero).
-
- * check/lightning.c, lib/jit_print.c, check/Makefile.am,
- check/all.tst: Update for the new qmul and qdiv instructions.
-
- * check/qalu.inc, check/qalu_div.ok, check/qalu_div.tst,

- simple test cases for qmul and qdiv.
-
-2013-01-30 Paulo Andrade <address@hidden>
-
- * doc/body.texi: Correct "jmpi" description that incorrectly
- told it was possible to pass any address as jump target. The
- only way to do that is "movi+jmpr".
-
-2013-01-30 Paulo Andrade <address@hidden>
-

-
- * configure.ac: Use AC_CONFIG_HEADERS instead of AC_CONFIG_HEADER
- to have HAVE_CONFIG_H defined with latest aclocal.
-
- * include/lightning/jit_private.h, lib/lightning.c: Add new
- abstraction to use an heuristic to calculate amount of space
- required for jit generation, and code to reallocate buffer if
- did miscalculate it.
-
- * lib/jit_arm.c, lib/jit_mips.c, lib/jit_ppc.c, lib/jit_x86.c:
- Update to use new code to estimate and resize of required buffer
- for jit code.
-
- * lib/jit_x86-cpu.c: Minor cosmetic change to avoid adding a
- non required rex prefix when calling a function pointer stored
- in a register.
-
-2013-01-24 Paulo Andrade <address@hidden>
-
- * check/Makefile.am: "make debug" target should pass only
- the main test tool program as argument for running gdb
-
- * configure.ac: Add the --enable-assertions options.
-
- * doc/Makefile.am, doc/body.texi, doc/lightning.texi:
- Major rewrite of the documentation to match the current
- implementation.
-
- * doc/version.texi: Automatic date update.
-
- * doc/ifib.c, doc/incr.c, doc/printf.c, doc/rfib.c, doc/rpn.c:
- Implementation of the documentation examples, that are also
- compiled during a normal build.
-
- * doc/p-lightning.texi, doc/porting.texi, doc/toc.texi,
- doc/u-lightning.texi, doc/using.texi: These files were
- renamed in the documentation rewrite, as the documentation
- was significantly trimmed due to full removal of the porting
- chapters. Better porting documentation should be added but
- for the moment it was just removed the documentation not
- matching the implementation.
-

- Make JIT_RET, JIT_FRET and JIT_SP private. These should not be
- used in any operations due to frequently having special
- constraints (usually JIT_FRET). JIT_FP must be made available
- because it must be used as the base register to access stack
- space allocated with jit_allocai.
-
-2013-01-14 Paulo Andrade <address@hidden>
-
- * include/lightning.h, lib/lightning.c: Add an extra align
- argument to the jit_data call (that should be made private),
- so that it should not align strings at 8 bytes.
- Correct the jit_note call to include the null ending byte
- when adding label/note names to the "jit data section".
-
-2013-01-11 Paulo Andrade <address@hidden>
-
- * lib/jit_note.c: New file implementing a simple string+integer
- annotation, that should be used to map filename and line number
- to offsets in the generated jit.
-
- * include/lightning.h, lib/lightning.c: Update for the new
- note code.
- Add an extra mandatory argument to init_jit, that is used
- as argument to bfd_openr.
- Change from generic void* to char* the argument to jit_note
- and add an extra integer argument, to map to filename and
- line number.
-
- * check/ccall.c, check/lightning.c, include/lightning/jit_private.h,
- lib/jit_arm.c, lib/jit_disasm.c, lib/jit_mips.c, lib/jit_ppc.c,
- lib/jit_print.c, lib/jit_x86.c: lib/Makefile.am: Update for the
- new annotation code.
-
- * configure.ac, check/Makefile.am: Update to work with latest
- automake.
-
-2013-01-09 Paulo Andrade <address@hidden>
-
- * include/lightning.h, lib/jit_arm.c, jit_mips-fpu.c,
- lib/jit_mips.c, lib/jit_print.c, lib/jit_x86.c, lib/lightning.c:
- Remove the jit_code_getarg_{f,d} and jit_code_pusharg{i,r}_{f,d}
- calls, replacing them with the new, internal only, jit_movr_w_f,
- jit_mov{r,i}_f_w, jit_movr_ww_d, and jit_mov{i,r}_d_ww, that
- better describe the operation being done, and allow removing
- the hackish code to detect special conditions for arm when
- moving from/to vfp from/to a grp register pair.
- Rename jit_code_retval_{f,d} to jit_code_x86_retval_{f,d} as
- it is specific to 32 bit x86, and used to move abi return
- value in x87 register to a sse register.
-
-2013-01-05 Paulo Andrade <address@hidden>
-
- * check/cccall.c, check/ccall.ok: New test case to validate
- interleaved calls from/to C code and jit.
-
- * check/Makefile.am: Update for the new ccall test case.
-
- * include/lightning.h, lib/lightning.c: Add the new jit_address
- call that returns the real/final address of a "note" in the
- generated jit. It requires a jit_node_t as returned by the
- jit_note call, and is only valid after calling jit_emit.
- Add an intermediate solution to properly handle arm
- soft and softfp modes that move a double to an integer register
- pair. Currently it just adds extra tests for the condition,
- but the proper solution should be to have extra lightning
- codes for these conditions, codes which should be only used
- by the backends that need it, and merged with the existing
- jit_pusharg*_{f,d}.
-
- * include/lightning/jit_private.h: Add new jit_state_t flag
- to know it finished jit_emit, so that calls to jit_address
- are valid.
-
- * lib/jit_mips.c: Correct abi implementation so that the
- new ccall test case pass. Major problem was using
- _jit->function.self.arg{i,f} as boolean values, but that
- would cause lightning.c:patch_registers() to incorrectly
- assume only one register was used as argument when calling
- jit_regarg_p(); _jit->function.self.arg{i,f} must be the
- number of registers used as arguments (in all backends).
-
- * lib/jit_x86.c: Add workaround, by marking %rax as used,
- to a special condition, when running out of registers and the
- allocator trying to spill and reload %rax, but %rax was used
- as a pointer to a function, what would cause the reload to
- destroy the return value. This condition can be better
- generalized, but the current solution is good enough.
-
- * include/lightning/jit_ppc.h, lib/jit_ppc-cpu.c, lib/jit_ppc.c:
- Rewrite logic to handle arguments, as the original code was
- written based on a SysV pdf about the generic powerpc ABI,
- what did "invent" a new abi for the previous test cases, but
- failed in the new ccall test in Darwin PPC. Now it properly
- handles 13 float registers for arguments, as well as proper
- computation of stack offsets when running out of registers
- for arguments.
-
-2013-01-02 Paulo Andrade <address@hidden>
-
- * check/float.tst: Correct test case to match ppc also
- converting positive infinity to 0x7fffffff.
-
- * lib/jit_arm-swf.c: Correct typos with double underscores.
-
- * lib/lightning.c: Correct remaining wrong reverse jump logic.
-
-2012-12-29 Paulo Andrade <address@hidden>
-
- * lib/lightning.c: Correct both, wrong and confusing logic
- to compute the reverse of a jump. Now it properly matches
- C semantics for "eq" (==) and "ne" (!=) and correct computation
- of reverse of "uneq" as "gt".
-
- * check/branch.tst: Update "ne" float branch check that
- previously happened to be wrongly tested with a NaN argument.
-
-2012-12-29 Paulo Andrade <address@hidden>
-
- * check/float.ok, check/float.tst: New test cases implementing
- extensive validation of float comparison and branch code
- generation as well as integer conversion, involving NaN and
- [+-]Inf.
-
- * lib/jit_arm-swf.c, lib/jit_x86-sse.c, lib/jit_x86-x87.c:
- Correct bugs found by new float test case.
-
- * lib/jit_x86.c: Correct cut&paste error added in commit to
- convert jit_arg* return value to a jit_node_t*, that would
- cause it to not properly handle double arguments in ix86.
-
- * check/Makefile.am: Update for the new test case.
-
-2012-12-28 Paulo Andrade <address@hidden>
-
- * check/lightning.c, include/lightning.h, lib/jit_arm.c,
- lib/jit_mips.c, lib/jit_ppc.c, lib/jit_print.c, lib/jit_x86.c,
- lib/lightning.c: Change return value of jit_arg{,_f,_d} to
- a jit_node_t* object, that should be used as argument to
- jit_getarg_{c,uc,s,us,i,ui,l,f,d}. This just requires changing
- from jit_int32_t to jit_pointer_t (or jit_node_t*) the "handle"
- for the getarg calls, with the benefit that it makes it easy
- to implement patching of the stack address of non register
- arguments, this way allowing to implement variable size stack
- frames if applicable; useful if there are too many registers and
- jit functions uses only a few callee save registers.
-
-2012-12-27 Paulo Andrade <address@hidden>
-
- * lib/jit_arm.c, lib/jit_mips-cpu.c, lib/jit_mips.c: Correct
- regressions when patching jit_calli for a forward function.
-
- * lib/jit_ppc-cpu.c: Correct wrong arguments to ANDI opcode
- in jit_getarg_u{c,s} implementation.
-
-2012-12-23 Paulo Andrade <address@hidden>
-
- * check/call.ok, check/call.tst: New test cases to validate
- simple typed argument and return values in function calls.
-
- * check/lightning.c: Properly handle jit_movi of labels for
- backward and forward code labels.
-
- * check/Makefile.am: Update for new test case.
-
-2012-12-23 Paulo Andrade <address@hidden>
-
- * check/carry.ok, check/carry.tst: New test case to validate

- * check/Makefile.am: Update for new test case.
-
-2012-12-22 Paulo Andrade <address@hidden>
-
- * lib/jit_ppc-cpu.c, lib/jit_ppc.c: Implement logic for
- jit_htonr for big endian, so that ppc (big endian) pass the
- new clobber.tst test case.
-
-2012-12-22 Paulo Andrade <address@hidden>
-
- * lib/jit_arm.c: Correct use of wrong argument offset
- variable in armv7l or float/double argument for varargs
- function in armv7hl.
- Correct jit_getarg* logic in software float mode to
- match expected behavior in other backends, that is, if
- a function is not called, it is safe to use a few lightning
- calls before a next jit_getarg* call, as done in the test
- case check/stack.tst. The proper solution should be to
- extend the parser in lib/lightning.c to check if there is
- some float operation that will call some (libgcc?) function,
- but software float arm should be a very uncommon backend for
- lightning, so, just load the already in place arguments
- saved to stack, assuming the register argument was clobbered
- (what should not be the case most times...).
-
-2012-12-22 Paulo Andrade <address@hidden>
-
- * check/clobber.ok, check/clobber.tst: New test case doing
- extensive validation tests to ensure registers not used in
- a operation are not clobbered.
-
- * check/Makefile.am: Update for new test case.
-
-2012-12-21 Paulo Andrade <address@hidden>
-
- * lib/lightning.c: Partially rewrite/revert code to compute
- initial register live state at the start of a basic block.
- The original logic was corrupted when adding optimizations
- to do as few computations as possible in jit_update. The
- reglive field must be always a known set of live registers
- at the start of a basic block. The value that was incorrect
- was the regmask field, that must be the set of registers
- that are in unknown state, because they are not known live,
- neither set (or possibly not set) in the basic block, and
- *must* store the state at the start of the basic block.
-
-2012-12-20 Paulo Andrade <address@hidden>
-
- * include/lightning/jit_ppc.h: Correct mismatch of JIT_F{1,5}
- with enum codes, that were correct, and returned by jit_f().
-
- * lib/jit_ppc-cpu.c, lib/jit_ppc-fpu.c, lib/jit_ppc.c: Properly
- implement and better describe values when generating stack
- frames.
-
-2012-12-18 Paulo Andrade <address@hidden>
-
- * check/stack.ok, check/stack.tst: New files to test data
- integrity on a deep chain of stack frames.

- lib/jit_mips-cpu.c, lib/jit_ppc.c, lib/jit_ppc-cpu.c,
- lib/jit_x86.c, lib/jit_x86-cpu.c: Calculate _jit->function->stack
- in the emit stage, otherwise it will calculate it wrong if
- need to jit_allocai space to spill registers.
-
- * lib/lightning.c: Correct wrong offset when updating the
- "current" jit function pointer in the code that may need to
- allocate stack space to spill registers.
-
- * check/lightning.c: Correct off by one data space check.
-
- * check/Makefile.am: Update for new test case.

-2012-12-17 Paulo Andrade <address@hidden>
-
- * check/fop_abs.ok, check/fop_abs.tst, check/fop_sqrt.ok,
- check/fop_sqrt.tst: New files implementing simple test cases
- for the extra float operations.
-
- * check/Makefile.am: Update for new test cases.
-
- * check/alu.inc: Add an extra macro to check for unordered
- equality on tests where it is expected to use NaN as an
- argument.
-
- * check/lightning.c: Minor change for proper/common argument
- syntax handling ommiting arguments to options.
-
-2012-12-17 Paulo Andrade <address@hidden>
-
- * check/Makefile.am: Automatically generate pattern list
- of tests with alternate jit generation options. This should
- prevent typos and needing to change multiple places after
- a change.
-
-2012-12-14 Paulo Andrade <address@hidden>
-
- * check/lightning.c: Remove the ".cpu name value" syntax,
- as it was not able to do proper changes before the jit
- internal data structure was initialized. Now it supports
- several getopt options to force using different jit
- generation options, effectively replacing the previous
- syntax.
-
- * check/run-test: Add simple extra logic to handle differently
- named test scripts, used to test things like x87 coprocessor
- in ix86, and arm instruction set or software float in armv7l.
-
- * configure.ac: Add some AC_RUN_IFELSE calls to figure at
- compile time if can test different code generation options,
- and update Makefile generation accordingly.
-
- * check/Makefile.am, lib/jit_arm.c, lib/jit_x86.c: Update to
- properly work with the test tool updating the jit_cpu global
- information.
-
- * check/check.arm.sh, check/check.swf.sh, check/check.x87.sh:
- New wrapper files passing -mthumb=0, mvfp=0 and -mx87=1 to
- the test tool, if applicable, so that it can validate alternate
- code generation options on test hosts that support them.
-
-2012-12-14 Paulo Andrade <address@hidden>
-
- * lib/jit_x86-x87.c, lib/jit_x86.c: Correct test cases in ix86
- when using the x87 coprocessor instead of sse2+.

- * include/lightning.h, include/lightning/jit_private.h,
- lib/jit_arm.c, lib/jit_mips.c, lib/jit_ppc.c, lib/jit_x86.c,
- lib/lightning.c: Make jit_ellipsis implementation not
- backend specific. It is not intended to handle va_list
- like objects at runtime, as jit_arg* and jit_getarg*
- return constant values resolved at parse time, so, effectively
- it is not possible to create printf like jit functions, as
- there is no va_start, va_arg, va_end, etc, abstraction. This
- limitation should be kept for the sake of making new ports
- easier.
-
-2012-12-14 Paulo Andrade <address@hidden>
-
- * include/lightning.h, lib/lightning.c: Add two extra wrapper
- functions to avoid need for excess pointer to/from word casts.
-
- * check/lightning.c: Only need for pointer to/from word cast
- now is jit_movi, update accordingly.
-
-2012-12-13 Paulo Andrade <address@hidden>
-
- * check/varargs.ok, check/varargs.tst: New test cases implementing
- simple varargs calls with a large amount of arguments to exercise
- excess arguments on stack.
-
- * include/lightning.h: Include config.h if HAVE_CONFIG_H is
- defined.
-
- * lib/jit_arm.c: Allocate a fpr register, not a gpr one for
- temporary when pushing varargs arguments in the stack.
-
- * lib/jit_arm-swf.c: Correct code changing the wrong offset
- in jit_absr_d and jit_negr_d in software float.
-
- * lib/jit_mips.c: Correct calculation of offsets of arguments
- on stack.
-
- * lib/jit_ppc.c: Correct bogus logic for "next" offset of arguments
- on stack and adjust for fixed offset of stack arguments.
-

-
- * include/lightning.h, lib/jit_arm.c, lib/jit_mips.c,
- lib/jit_ppc.c, lib/jit_x86.c, lib/lightning.c: Change jit_prepare
- to no longer receive an argument. If receiving an argument, it
- should be an ABI specifier, not a boolean if varargs or not,
- and add the new jit_ellipsis call, to specify where the
- ellipsis is in the C prototype of the function being called.
- Note that currently it is not supported to define varargs
- functions and it will be ignored if calling jit_ellipsis not
- in a prepare/finish* block, but this should be addressed.

-2012-12-11 Paulo Andrade <address@hidden>
-
- * lib/jit_ppc-cpu.c: Make movr a function that checks arguments
- so that other code can safely assume it is a noop if src and dst
- are the same register.
- Implement rem{r,i}{,_u} as a div{,u}/mul/sub.
- Correct ANDIS, ORIS and XORIS calls to cast the argument to
- unsigned before the shift to avoid an assertion if the argument
- had the topmost bit set.
- Implement lshi, rshi and rshi_u as functions to test for a
- zero argument, that would otherwise trigger an assertion when
- computing the shift value.
- Do a simple implementation of bm{s,c}{r,i} with a temporary,
- "andr" of arguments and jump based on comparison with zero.
- Correct typo in ldxi_c.
-
- * lib/jit_ppc-fpu.c: Correct wrong arguments to FDIV* and STF*.
-
- * lib/jit_ppc.c: Correct wrong check for 6 instead of 8 integer
- arguments in registers. If calling a varargs function and
- passing a float or double argument, also either store the
- value in the stack or in integer registers, as varargs functions
- do not fetch it from float registers.
- Add "case" for new functions and incorrectly missing ones.
- Call libgcc's __clear_cache, that should know what to do
- if the hardware needs flushing cache before execution.
-
- * lib/lightning.c: Do a simple/trivial logic in jit_regset_scan1,
- that should make it easier for the compiler to optimize it, and
- that also corrects the previously wrong code for big endian, and
- that was causing problems in ppc due to not saving all callee save
- registers as it was not "finding" them in the regset due to the
- little endian assumption bug.
-
-2012-12-11 Paulo Andrade <address@hidden>
-
- * configure.ac: Only default to using the builtin disassembler
- if on GNU/Linux. This should be temporary, due to requiring
- /proc/self/exe.
- Correctly check $target_cpu for powerpc.
-
- * include/lightning/jit_ppc.h: Correctly implement jit_v_num.
-
- * include/lightning/jit_private.h: Declare proper prototype
- for jit_init_debug and jit_finish_debug.
-
- * lib/jit_ppc-cpu.c: Remove code to save/restore callee save
- float registers, as it is not required since those float
- registers are not usable currently.
- Change prolog and epilog generation to, at least comparing
- code, match what gcc generates in "gcc -O0", but it is still
- failing in Darwin PPC, apparently due to the __clear_cache
- call not being enough, as frequently it will also fail to
- execute, and the code buffer is all zeroes.
-
- * lib/lightning.c: Do not fail in jit_regset_scan1 calls due
- to passing 64 as argument on computers with 64 registers.
-
-2012-12-10 Paulo Andrade <address@hidden>
-
- * lib/jit_mips-cpu.c: Correct all current test cases.
- Call the "xori" not the "XORI" macro for jit_xori implementation,
- as the XORI macro handles only 16 bit unsigned values.
- Call the "movr" macro, not the "movi" macro in the special
- case of adding or subtracting zero.
- Use the proper temporary register in the jit_andr implementation.

-
- * check/Makefile.am: Update for new test cases.
-
- * include/lightning/jit_private.h: Make the jit_reg_free_p
- macro shared by all backends. Previously was added for the
- arm backend, but is useful in the x86_64 backend when checking
- state of "special purpose register".
- Also add the new jit_class_named register class, that must be
- or'ed with the register value if calling jit_get_reg expecting
- an specific value, because the specific register value may be
- zero, that previously was treated as no register requested.
-
- * lib/jit_arm-cpu.c: Correct argument order for T2_MVN.
-
- * lib/jit_arm-swf.c: Call the proper function for double
- divide. The "software float" implementation just calls
- libgcc functions.
-
- * lib/jit_arm.c: Return float/double values in the float
- register if using the hard float ABI.
-
- * lib/jit_x86-cpu.c: Change the can_sign_extend_int_p macro
- to not include -0x80000000L, because there is code that
- "abuses" it and thinks it can negate the immediate value
- after calling that macro.
- Correct implementation of jit_subi that had a wrong code
- patch logic doing subtraction with reversed arguments.
- Correct REX prefix calculation in the jit_muli implementation.
- Correct logic to get/unget %*ax and %*dx registers in divremr
- and divremi.
- Correct divremi that was using the symbolic, unique %*ax
- value in on place (not using the _REGNO name suffix).
- Correct cut&paste error causing it to use "xor" instead of
- "or" in one code path of the jit_ori implementation.
- Correct several flaws when clobbering registers and/or when
- one of the arguments was %*cx in the rotshr wrapper function
- implementing most shift operations.
-
- * lib/lightning.c: No longer expect that the backend be smart
- enough to know what to do when asking for a named register
- if that register is already an argument or is live. It fails
- if it is an argument, or if register is live, fails if cannot
- spill.
- No longer incorrectly assume that eqr_{f,d} and ltgr_{f,d} are
- safe to inverse value tests in jump thread optimization.

- argument handling and make the mips backend pass the initial
- test cases.
-
- * include/lightning.h, ib/jit_print.c, lib/lightning.c:
- Add extra enum values for argument handling functions that
- could not be abstracted to the current codes, that is, when
- float values need to move from/to gpr from/to fpr. It would
- be more tempting to add such primitives, but they would have
- wordsize limitations, and it is not expected to add codes
- with one gpr argument for 64 bit and two for 32 bit.
-
- * lib/jit_ppc.c: Check _jit->function before calling jit_epilog()
- to avoid a runtime exception.
-
-2012-12-04 Paulo Andrade <address@hidden>
-
- * include/lightning/jit_mips.h, lib/jit_mips.c: Update to
- make the mips backend compile in a qemu image.
-
- * lib/jit_ppc.c: Minor adaptations to help in having the
- ppc backend compilable.
-
-2012-12-03 Paulo Andrade <address@hidden>
-
- * configure.ac, include/lightning/jit_private.h, lib/jit_arm-cpu.c,
- lib/jit_arm-swf.c, lib/jit_arm.c, check/Makefile.am: Correct
- implementation of the arm backend port to build and pass the
- current test cases. Tested on armv7 with softfp abi.
-
- * lib/jit_disasm.c: Rename and change prototype of static
- disassemble function as in the arm backend it is required
- to access state information stored in the jit_state_t object.
-
- * check/3to2.tst, check/add.tst: Correct test case code assuming
- JIT_RO and JIT_RET are the same, and even if they are the same,
- the logic was incorrect because it must always call jit_retval*
- to fetch a function call return before any other instruction.
- The arm backend hash a special condition if jit_retval is not
- called, because "r0" is not JIT_R0, but is JIT_RET and *also*
- the first argument for a called function, so JIT_RET must be
- only used as an argument to jit_retval.
-
-2012-12-03 Paulo Andrade <address@hidden>
-
- * check/all.tst, check/lightning.c: Only declare or use 64 bit
- interfaces on 64 bit builds.
-
- * check/fib.tst: Use simpler logic to not need preprocessor
- conditionals for 32 or 64 bit.
-
- * include/lightning.h: Only declare 64 bit macros on a 64 bit
- build. Code using lightning must know about wordsize and the
- jit generation limitations, also, this way it generates a
- compile time failure, not a runtime assertion.
-
- * include/lightning/jit_x86.h: Correct typo in macro name.
-
- * lib/jit_arm.c, lib/jit_arm-cpu.c, lib/jit_mips.c,
- lib/jit_mips-cpu.c, lib/jit_ppc.c, lib/jit_ppc-cpu.c,
- lib/jit_x86.c, lib/jit_x86-cpu.c: Correct wrong code to get
- current jit function pointer.
-
- * lib/lightning.c: Move call to the simplify() optimization
- to after register liveness is known. Previous code did work
- by accident but now with proper test cases the problem was
- noticed.
-
- * lib/jit_disasm.c: Always cast bfd_vma to long long when
- passing it as printf argument.
-
-2012-12-03 Paulo Andrade <address@hidden>
-
- * configure.ac, check/Makefile.am, check/check.sh,

- lib/jit_ppc-cpu.c, lib/jit_ppc-fpu.c, lib/jit_ppc.c: New
- files implementing initial code different jit backends.
-
- * include/lightning/jit_private.h: Add extra field to the
- private jit_patch_t type, required by the arm port.
-
- * lib/Makefile.am: Update for the new backend implementation
- files.
-
-2012-12-02 Paulo Andrade <address@hidden>
-
- * check/Makefile.am: Add proper "make clean" rule and missing

-
- * check/check.sh, check/run-test: New wrapper files for the

- must provide an alternative for software float.
-
- * lightning/ppc/core.h, lightning/sparc/core.h, tests/Makefile.am:
- Remove JIT_NEED_PUSH_POP. It is absolutely not trivial to implement
- properly on some backends due to stack alignment constraints, and
- whenever it is required, using jit_allocai and using a properly
- aligned stack vector, or a heap buffer, is better.
