* 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.
* 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.
* 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.
* 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.
