* 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.
* 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.
