* 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.
* 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_sparc-sz.c, lib/jit_sparc.c, lib/jit_x86-sz.c, lib/jit_x86.c:
Update for the new jit_va_push interface.
* 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.
* 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_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.
* include/lightning.h: Split jit_htonr in the new 3 interfaces
jit_htonr_us, jit_htonr_ui and jit_htonr_ul, the later only
available on 64 bit. The plain/untyped jit_htonr macro call
maps to the wordsize one.

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

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).
* 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.
* lib/jit_print.c: Minor change to not duplicate jit_names.c
contents.
* lib/jit_aarch64-sz.c, lib/jit_alpha-sz.c, lib/jit_arm-sz.c,

lib/jit_x86-sz.c: Rewritten to add string representation of

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_ia64-sz.c, lib/jit_mips-sz.c, lib/jit_ppc-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.
* 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.
* 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.
