2018-04-20 Paulo Andrade <pcpa@gnu.org>
* 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.
* include/lightning/jit_sparc.h, lib/jit_sparc-cpu.c, lib/jit_sparc-fpu.c,
lib/jit_sparc-sz.c, lib/jit_sparc.c: Update for 64 bits sparc.
* lib/lightning.c: Update for new jit_regset_t required for sparc64.
2018-02-26 Paulo Andrade <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* lib/lightning.c: Avoid deep recursions when computing live
register ranges.
2018-01-31 Paulo Andrade <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* lib/jit_aarch64-fpu.c, lib/jit_aarch64.c: Correct base
aarch64 varargs code.
2015-05-24 Paulo Andrade <pcpa@gnu.org>
* check/lightning.c: Clearly run check if clang is the system
compiler.
2015-05-20 Paulo Andrade <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* lib/jit_ia64.c: Implement inline assembly cache flush,
required on multiprocessor systems.
2015-05-06 Paulo Andrade <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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_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 <pcpa@gnu.org>

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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>

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.

lib/jit_ia64.c, lib/jit_mips.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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* configure.ac, lib/jit_disasm.c: Rewrite workaround

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.

lib/jit_s390x.c, lib/jit_size.c, lib/lightning.c:
Add support for generating jit for s390 32 bit. This change
also removed %f15 from the list of temporaries fpr registers;
it was not being used, but if were, it would corrupt the
stack frame because the spill address would overwrite grp
offsets.
2014-12-26 Paulo Andrade <pcpa@gnu.org>
* lib/jit_ppc-cpu.c, lib/jit_ppc.c: Correct some endianess issues
on the powerpc le backend.

* lib/jit_ppc-cpu.c: Add mcrxr instruction emulation,
as this instruction has been phased out, and should be
implemented as a kernel trap.
2014-12-26 Paulo Andrade <pcpa@gnu.org>
* lib/jit_arm.c: Better check for need to flush constants

2014-12-25 Paulo Andrade <pcpa@gnu.org>
* include/lightning.h: Split jit_htonr in the new 3 interfaces

maps to the wordsize one.

Update for the new jit_htonr* interfaces.
* check/Makefile.am: Update for new test cases.

lib/jit_x86-sz.c, lib/jit_x86-x87.c, lib/jit_x86.c,
size.c: Implement support for the x32 abi. Built and
tested on Gentoo default/linux/amd64/13.0/x32 profile.
2014-12-24 Paulo Andrade <pcpa@gnu.org>
* lib/jit_names.c: Add missing rsbi_f and rsbi_d strings.
2014-12-21 Paulo Andrade <pcpa@gnu.org>
* lib/jit_arm.c: Call __clear_cache for every page.
This should only be required for older boards or
toolchain setup, but has been reported to be required
for lightning at some point.
2014-12-21 Paulo Andrade <pcpa@gnu.org>
* lib/jit_arm.c: Correct check to guard overflow of index
of constants from program counter.
2014-11-24 Paulo Andrade <pcpa@gnu.org>
* lib/lightning.c: Remove an optimization to calee save
registers that may incorrectly remove a jit_movr under
special conditions.
2014-11-20 Paulo Andrade <pcpa@gnu.org>
* include/lightning/jit_ppc.h, lib/jit_ppc-cpu.c,
lib/jit_ppc.c: Add initial powerpc le support.
2014-11-20 Paulo Andrade <pcpa@gnu.org>
* lib/jit_disasm.c: Change thumb or arm disassemble based on
jit code before disassembly.
* lib/jit_arm-cpu.c: Correct reversed arguments to LDRD and
STRD instructions, and correct checking for support of those.
* lib/jit_arm-swf.c: Correct wrong use of LDRD and STRD and
only use those if the register is even.
* check/check.arm.swf.sh, check/check.arm4.swf.sh: New files
to test LDRD and STRD, as well as the alternate code path
when those are not available, in the .arm4. test case.
* check/Makefile.am: Update for the new test cases.

lib/jit_ia64.c, lib/jit_mips.c, lib/jit_ppc.c,
lib/jit_s390x.c, lib/jit_sparc.c, lib/jit_x86.c:
Implement a private jit_flush call, that flushes
the cache, if applicable, aligning down to the
previous and up to the next page boundary.
2014-11-08 Paulo Andrade <pcpa@gnu.org>
* check/ctramp.c: New file. It just repeats the test
of tramp.tst, but using two jit_state_t, what should
test possible issues with two contexts, and also validate
jit_tramp works on backends with function descriptions.
* check/Makefile.am: Update for new test case.
2014-11-03 Paulo Andrade <pcpa@gnu.org>
* include/lightning/jit_mips.h: Do not make the t9 register
JIT_R11 (or JIT_R7 for n32 or n64 abi) available. Previously
it cause problems if one expects it to not be changed in a
function call. For example, calling a jit function, where it
really does not need to be changed.
2014-10-26 Paulo Andrade <pcpa@gnu.org>
* lib/jit_aarch64.c, lib/jit_alpha.c, lib/jit_arm.c,
lib/jit_hppa.c, lib/jit_ia64.c, lib/jit_mips.c, lib/jit_ppc.c,
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
_bmsi and _bmci on x86), but no other case was found,
after running make check, with assertions enabled, on all
backends.
2014-10-26 Paulo Andrade <pcpa@gnu.org>
* lib/jit_x86-cpu.c: Correct a register allocation leak in
_bmsi and _bmci.
2014-10-25 Paulo Andrade <pcpa@gnu.org>
* lib/jit_disasm.c: Do not cause an fatal error if init_jit
fails in the jit_init_debug call.
2014-10-24 Paulo Andrade <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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.
2014-10-17 Paulo Andrade <pcpa@gnu.org>

lib/jit_x86-sse.c, lib/jit_x86-sz.c, lib/jit_x86-x87.c,
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
(left operand).
2014-10-17 Paulo Andrade <pcpa@gnu.org>
* lib/jit_names.c: New file with single definition of string
representation of lightning IR codes.
* size.c: Modified to append the code name in a C comment
after the maximum instruction size.

contents.

lib/jit_hppa-cpu.c, lib/jit_mips-cpu.c, lib/jit_ppc-cpu.c,
lib/jit_sparc-cpu.c: Implement or correct the internal
nop(count) call that receives an argument that tells the
modulo bytes to align the code for the next instruction.
* include/lightning.h, lib/lightning.c, lib/jit_aarch64.c,
lib/jit_alpha.c, lib/jit_arm.c, lib/jit_hppa.c, lib/jit_ia64.c,
lib/jit_mips.c, lib/jit_ppc.c, lib/jit_s390x.c, lib/jit_sparc.c,
lib/jit_x86.c: Implement the new jit_align() call that receive
an argument, that tells the modulo, in bytes, to align the
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
labels, but not guaranteed to be aligned at word size bytes.
* check/align.ok, check/align.tst: New files, implementing
a simple test for the new jit_align() interface.
* check/Makefile.am, check/lightning.c, lib/jit_aarch64-sz.c,
lib/jit_alpha-sz.c, lib/jit_arm-sz.c, lib/jit_hppa-sz.c,

lib/jit_print.c, lib/jit_s390x-sz.c, lib/jit_sparc-sz.c,
lib/jit_x86-sz.c: Update for the new jit_code_align code and
the jit_align() interface.
2014-10-13 Paulo Andrade <pcpa@gnu.org>
* include/lightning.h, lib/jit_size.c, size.c: Use a
symbolic value for the last IR code.
2014-10-12 Paulo Andrade <pcpa@gnu.org>
* include/lightning.h, include/lightning/jit_private.h,
lib/jit_aarch64-cpu.c, lib/jit_alpha-cpu.c, lib/jit_arm-cpu.c,

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
jit_tramp.
2014-09-29 Paulo Andrade <pcpa@gnu.org>
* lib/jit_aarch64.c, lib/jit_alpha.c, lib/jit_arm.c,
lib/jit_hppa.c, lib/jit_ia64.c, lib/jit_mips.c,
lib/jit_ppc.c, lib/jit_s390x.c, lib/jit_sparc.c,
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 <pcpa@gnu.org>
* 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.
2014-09-24 Paulo Andrade <pcpa@gnu.org>
* check/lightning.c: Add workaround to conflicting global
optind variable in cygwin binutils that have an internal
getopt* implementation.
* lib/jit_x86-cpu.c: Add a simple define ffsl ffs if building
for 32 bit and there is no ffsl function.
2014-09-24 Paulo Andrade <pcpa@gnu.org>
* check/lightning.c: Add a hopefully temporary kludge to not use
sprintf and sscanf returned by dlsym. This is required to pass
the varargs test.
* 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.
* check/check.x87.nodata.sh: New file, previously used but that
was missing git.
2014-09-07 Paulo Andrade <pcpa@gnu.org>
* lib/lightning.c: Mark all registers advertised as live, as
per jit_callee_save_p as live whenever reaching a jump that
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 <pcpa@gnu.org>
* 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.
2014-08-29 Paulo Andrade <pcpa@gnu.org>
* doc/body.texi: Add a proper info menu entry for
GNU lightning.
* doc/version.texi: Regenerate.
2014-08-16 Paulo Andrade <pcpa@gnu.org>

lib/jit_x86-cpu.c, lib/jit_x86-sse.c,
lib/jit_x86-x87.c: Review generation of all branch
instructions and always adds the jit_class_nospill
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
if one uses the not exported jit_get_reg and jit_unget_reg
calls and cause enough register starvation.
2014-08-16 Paulo Andrade <pcpa@gnu.org>
* lib/jit_alpha.c: Correct wrong bitmask of most argument
float register arguments, that were being set as callee
save instead of argument registers class.
2014-08-16 Paulo Andrade <pcpa@gnu.org>
* lib/jit_arm-sz.c: Regenerate table of known maximum
instruction sizes for the software float fallback,
that implements "virtual" float registers in the stack
and operations as calls to libgcc.
* size.c: Correct typo in the generated jit_arm-sz.c file.
2014-08-10 Paulo Andrade <pcpa@gnu.org>
* include/lightning/jit_alpha.h, lib/jit_alpha-cpu.c,
lib/jit_alpha-fpu.c, lib/jit_alpha-sz.c, lib/jit_alpha.c:
New files implementing a lightning Alpha port. Thanks
to Trent Nelson and snakebit.net staff for providing access
to an Alpha system.
* check/float.tst, check/lightning.c, configure.ac,
include/lightning.h, include/lightning/Makefile.am,
include/lightning/jit_private.h, lib/Makefile.am,
lib/jit_disasm.c, lib/jit_size.c, lib/lightning.c:
Minor changes to adapt for the new Alpha port.
2014-08-10 Paulo Andrade <pcpa@gnu.org>
* lib/lightning.c: Always mark JIT_RET and JIT_FRET as
live in a function epilog. This is required because
on some ports a complex sequence, allocating one or more
registers, may be required to jump from a ret* to the
epilog, and the lightning api does not have annotations
to know if a function returns a value, or the type of
the return value.
2014-08-10 Paulo Andrade <pcpa@gnu.org>
* lib/lightning.c: Change the correct live bitmask of
return registers after a function call in jit_update.
2014-08-10 Paulo Andrade <pcpa@gnu.org>
* lib/lightning.c: Change assertions to have an int
result and correct a bad bit mask assertion.
2014-08-10 Paulo Andrade <pcpa@gnu.org>
* lib/jit_aarch64.c: Correct bad setup for assertion
of consistency before a patch.
2014-08-10 Paulo Andrade <pcpa@gnu.org>
* lib/jit_mips-cpu.c: Correct typo in the jit_bmsr
implementation that was using the wrong test result
register.
2014-07-28 Paulo Andrade <pcpa@gnu.org>
* lib/jit_memory.c: Do not call free on NULL pointers.
* include/lightning/jit_private.h, lib/jit_note.c,
lib/lightning.c: Add a wrapper to memcpy and memmove
to not actually call those functions with a zero size
argument, and likely also a null src or dst.
2014-07-27 Paulo Andrade <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* include/lightning/jit_aarch64.h, include/lightning/jit_arm.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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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_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 <pcpa@gnu.org>
* lib/jit_x86-x87.c: Correct wrong optimization when
loading the log(2) constant.
2013-12-03 Paulo Andrade <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* include/lightning/jit_mips.h: Add proper mips abi detection.
2013-09-30 Paulo Andrade <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* lib/jit_arm.c: Correct build when disassembler is
disabled.
2013-09-25 Paulo Andrade <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* lib/jit_aarch64-sz.c, lib/jit_arm-sz.c, lib/jit_hppa-sz.c,
lib/jit_ia64-sz.c, lib/jit_mips-sz.c, lib/jit_ppc-sz.c,
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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* lib/jit_s390x-cpu.c: Spill/reload correct callee save
float registers.
2013-09-10 Paulo Andrade <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* lib/jit_ia64-cpu.c: Correct incorrect logic when restoring
the value of the "r2" callee save register.
2013-08-29 Paulo Andrade <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* lib/jit_s390x-cpu.c: Correct code checking if immediate
fits instruction, but using the negated value.
2013-07-28 Paulo Andrade <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* lib/jit_aarch64.c: Remove unused macros left from cut&paste
of jit_arm.c.
2013-07-16 Paulo Andrade <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* NEWS, THANKS, configure.ac, doc/version.texi: Update for
the 1.99a second alpha release.
2013-06-25 Paulo Andrade <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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.
2013-06-01 Paulo Andrade <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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.
2013-04-26 Paulo Andrade <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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.
2013-04-10 Paulo Andrade <pcpa@gnu.org>
* include/lightning/jit_private.h, lib/jit_arm.c,
lib/jit_mips-cpu.c, lib/jit_mips.c, lib/jit_ppc-cpu.c,
lib/jit_ppc.c, lib/jit_print.c, lib/jit_sparc-cpu.c,
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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* check/lightning.c: Add missing ppc preprocessor definition.
2013-03-06 Paulo Andrade <pcpa@gnu.org>
* 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.
2013-03-06 Paulo Andrade <pcpa@gnu.org>
* include/lightning/jit_private.h, lib/jit_arm-cpu.c,
lib/jit_arm.c, lib/jit_disasm.c, lib/jit_mips-cpu.c,
lib/jit_mips.c, lib/jit_note.c, lib/jit_ppc-cpu.c,
lib/jit_ppc.c, lib/jit_print.c, lib/jit_sparc-cpu.c,
lib/jit_sparc.c, lib/jit_x86-cpu.c, lib/jit_x86.c,
lib/lightning.c: Add an extra structure for data storage
during jit generation, and release it after generating
jit, to reduce a bit memory usage, and also to make it
easier to understand what data is available during
jit runtime.
2013-03-06 Paulo Andrade <pcpa@gnu.org>
* lib/lightning.c: Make data and code buffer readonly.
2013-02-20 Paulo Andrade <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* doc/body.texi: Add back the SPARC code generation example.
2013-02-19 Paulo Andrade <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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.
2013-02-17 Paulo Andrade <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
*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 <pcpa@gnu.org>
* lib/jit_ppc-cpu.c, lib/jit_ppc.c: Validate and correct
problems in the qmul and qdiv ppc implementation.
2013-02-04 Paulo Andrade <pcpa@gnu.org>
* include/lightning.h, include/lightning/jit_private.h,
lib/jit_arm-cpu.c, lib/jit_arm.c, lib/jit_mips-cpu.c,
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,
check/qalu_mul.ok, check/qalu_mul.tst: New files implementing
simple test cases for qmul and qdiv.
2013-01-30 Paulo Andrade <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* lib/jit_x86-cpu.c: Correct undefined behavior code.
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56143
2013-01-29 Paulo Andrade <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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.
2013-01-18 Paulo Andrade <pcpa@gnu.org>
* lib/jit_note.c: Correct bounds check and wrong code keeping
a pointer that could be changed after a realloc call.
2013-01-18 Paulo Andrade <pcpa@gnu.org>
* check/3to2.tst, check/add.tst, check/allocai.tst, check/bp.tst,
check/call.tst, check/ccall.c, check/clobber.tst, check/divi.tst,
check/fib.tst, check/ldsti.tst, check/ldstr-c.tst, check/ldstr.tst,
check/ldstxi-c.tst, check/ldstxi.tst, check/ldstxr-c.tst,
check/ldstxr.tst, check/lightning.c, check/rpn.tst, check/stack.tst,
check/varargs.tst, include/lightning.h,
include/lightning/jit_private.h, lib/jit_arm.c, lib/jit_disasm.c,
lib/jit_mips.c, lib/jit_note.c, lib/jit_ppc.c, lib/jit_print.c,
lib/jit_x86.c, lib/lightning.c: Extend the "jit_note" abstraction
with the new "jit_name" call, that receives a string argument, and
should usually be called to mark boundaries of functions of code
generating jit (that is, it is not expected that the language
generating jit map its functions to jit functions).
2013-01-17 Paulo Andrade <pcpa@gnu.org>
* check/add.tst, check/allocai.tst, check/bp.tst, check/divi.tst,
check/fib.tst, check/lightning.c, include/lightning/jit_arm.h,
include/lightning/jit_mips.h, include/lightning/jit_ppc.h,
include/lightning/jit_private.h, include/lightning/jit_x86.h:
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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* check/carry.ok, check/carry.tst: New test case to validate
carry condition handling.
* check/Makefile.am: Update for new test case.
2012-12-22 Paulo Andrade <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* check/stack.ok, check/stack.tst: New files to test data
integrity on a deep chain of stack frames.
* 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: 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* lib/jit_x86-x87.c, lib/jit_x86.c: Correct test cases in ix86
when using the x87 coprocessor instead of sse2+.
2012-12-14 Paulo Andrade <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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.
2012-12-12 Paulo Andrade <pcpa@gnu.org>
* 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.
* check/allocai.tst, check/alu_add.tst, check/alu_and.tst,
check/alu_com.tst, check/alu_div.tst, check/alu_lsh.tst,
check/alu_mul.tst, check/alu_neg.tst, check/alu_or.tst,

check/lightning.c: Update for the change to jit_prepare and
addition of jit_ellipsis.
2012-12-11 Paulo Andrade <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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.
2012-12-09 Paulo Andrade <pcpa@gnu.org>
* check/alu.inc, check/alu_add.ok, check/alu_add.tst,
check/alu_and.ok, check/alu_and.tst, check/alu_com.ok,

check/alu_xor.tst, check/alux_add.ok, check/alux_add.tst,
check/alux_sub.ok, check/alux_sub.tst, check/branch.ok,
check/branch.tst: New test cases for arithmetic and branch
tests.
* 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.
2012-12-05 Paulo Andrade <pcpa@gnu.org>
* check/Makefile.am, check/cvt.ok, check/cvt.tst: Add new
"cvt" test case to test conversion from/to int/float types.
* check/lightning.c: Only define truncr_{f,d}_l in 64 bit mode.
* include/lightning.h: Correct typo that caused it to define
jit_truncr_{f,d}_l in 32 bit mode.
* lib/jit_arm-cpu.c: Avoid assertion failure in the signed/unsigned
extend opcodes generation as it shares an interface for 3 argument
opcode generation.
* lib/jit_x86-cpu.c: Correct wrong argument passed to
jit_unget_reg in the andi implementation and wrong byte
unsigned extend code generation.
* lib/jit_x86-sse.c: Correct conversion from "word" to float or
double as is dependent on wordsize.
2012-12-05 Paulo Andrade <pcpa@gnu.org>
* check/ldstr-c.ok, check/ldstr-c.tst, check/ldstxi-c.ok,
check/ldstxi-c.tst, check/ldstxr-c.ok, check/ldstxr-c.tst:
New test case files testing load clobbering the base and/or
index register;
* check/ldst.inc: New file with common definition for all the
ldst* test cases.
check/Makefile.am, check/ldsti.tst, check/ldstr.tst,
check/ldstxi.tst, check/ldstxr.tst: Update for new common
definitions file and new register clobber ldst tests.
2012-12-05 Paulo Andrade <pcpa@gnu.org>
* lib/jit_mips-fpu.c: Correct wrong register order in stxr_{f,d}
in the mips backend.
2012-12-05 Paulo Andrade <pcpa@gnu.org>
* lib/jit_arm-vfp.c: Correct regression found in armv7l with
latest test cases.
2012-12-05 Paulo Andrade <pcpa@gnu.org>
* check/ldstxi.tst, check/ldstxr.tst: Correct wrong argument
order for 32 bit mode tests.
* configure.ac: Correct check for ix86 target_cpu.
2012-12-05 Paulo Andrade <pcpa@gnu.org>
* check/ldstr.ok, check/ldstr.tst, check/ldsti.ok,
check/ldsti.tst, check/ldstxr.ok, check/ldstxr.tst,
check/ldstxi.ok, check/ldstxi.tst:
New test case files exercising a very large amount of
register combinations to verify load/store implementation.
* check/Makefile.am: Update for new test cases.
* lib/jit_x86-cpu.c: Correct wrong argument order when
computing REX prefix for {ld,st}r_T codes;
2012-12-04 Paulo Andrade <pcpa@gnu.org>
* lib/jit_mips-fpu.c, lib/jit_mips.c: Implement missing mips
jit_sqrtr_{f,d} codes.
* check/all.tst, include/lightning.h, lib/jit_print.c: Change
declaration order and call order in all.tst of {add,sub}c and
{add,sub}x. *c must be called before to set the carry and *x
second to use the carry and keep it set. The wrong call order
was causing all.tst to fail in mips, where a register is
allocated to keep a global carry state.
2012-12-04 Paulo Andrade <pcpa@gnu.org>
* include/lightning/jit_mips.h, lib/jit_mips-cpu.c,
lib/jit_mips-fpu.c, lib/jit_mips.c: Correct float/double
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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* 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 <pcpa@gnu.org>
* configure.ac, check/Makefile.am, check/check.sh,
doc/Makefile.am, include/lightning/Makefile.am,
lib/Makefile.am: Correct make distcheck.
2012-12-02 Paulo Andrade <pcpa@gnu.org>
* lib/jit_ppc.c: Assign copyright ownership to FSF.
* lib/jit_x86-cpu.c: Correct integer multiplication that was
generating code with reversed register arguments.
* check/rpn.ok, check/rpn.tst: New test case file.
2012-12-02 Paulo Andrade <pcpa@gnu.org>
* lib/jit_x86-cpu.c, lib/jit_x86-sse.c, lib/jit_x86-x87.c:

* 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 <pcpa@gnu.org>
* check/Makefile.am: Add proper "make clean" rule and missing
check.sh to EXTRA_DIST.
2012-12-02 Paulo Andrade <pcpa@gnu.org>
* .gitignore: Update pattern of ignored files.
* check/Makefile.am: Add rule to build liblightning.la dependency
in case of running "make check" before building the library.

* check/Makefile.am: New test suite makefile.
* check/check.sh, check/run-test: New wrapper files for the
new test suite.
* check/lightning.c: New file. The main driver of the new test
suite, that compiles to a parser of a very simple assembly like
language, generates jit and executes it.
* check/all.tst: New file. A generic debug and sample test file
with a directive to prevent it from being executed, and useful to

written from scratch, only by <pcpa@gnu.org>, and have now
copyright assignment to the FSF. This is the core of the new
lightning rework. Previously it was integrated in code with
a garbage collector and several custom types like vectors and
hash tables, so this first code merge with lightning converts
that code into a library extracting only the jit bits, and at
first only for x86_64 GNU/Linux.
* lightning.h, m4/lightning.m4: Removed. These are no longer
required in the new lightning code.
.gitignore, Makefile.am, configure.ac: Update for the new
lightning code.
2012-12-02 Paulo Andrade <pcpa@gnu.org>
* .cvsignore: Removed for extra cleanup.
* build-aux: Rename directory to m4.

autogenerated files that also generate too much diff noise when
regenerated in git.
* build-aux/help2man, build-aux/texinfo.tex, build-aux/texi2dvi:
Removed. Buildenvironment must have an up to date version from

* build-aux/config.guess, build-aux/config.sub, build-aux/depcomp,
build-aux/install-sh build-aux/mdate-sh build-aux/missing: Removed.
Do not maintain a copy of automake files in git. Release tarballs
must use an up to date version.
* lightningize.in, doc/lightningize.1: Removed. Do not encourage
bundling lightning in other packages. It should use a system package
or a proper thirdy part subdirectory.
* INSTALL: Removed. Autoreconf removes it and creates a symlink
when regenerating files, so, avoid conflicts in git and let
automake create the symlink.
* .gitignore: Add INSTALL and autogenerated files.

Remove LIGHTNING_CROSS, it is half supported and incomplete.
* tests/3to2.c, tests/funcfp.c, tests/rpnfp.c: Remove preprocessor
check on JIT_FPR. If no hardware registers are available, the backend
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
