* 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/alu_rsb.ok, check/alu_rsb.tst: New files implementing
tests for jit_rsb*.
* check/Makefile.am, check/lightning.c, include/lightning.h,

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).
* 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.
* check/float.tst: Add sparc to list of known NaN and +-Inf
to integer conversion.
* check/lightning.c: Define __sparc__ to preprocessor in
the sparc backend.
* include/lightning/jit_private.h: Correct wrong definition
of emit_stxi_d, that has lived for a long time, but would
cause problems whenever needing to spill/reload a float
register.
* include/lightning/jit_sparc.h: Can only use %g2,%g3,%g4
for scratch variables, as other "global" registers are
reserved for the system, e.g. libc.
Reorder float register naming to make it easier to
access odd float registers, so that generating code for
pusharg and getarg is easier for the IR.
* lib/jit_mips-cpu.c, lib/jit_ppc-cpu.c: Update to match
new code in jit_sparc-cpu.c. It must call jit_get_reg
with jit_class_nospill if using the register to move
an unconditional branch address to it, as the reload
will not happen (actually could happen in the delay
slot...)
* lib/jit_sparc-cpu.c: Correct wrong macro definition for
ldxr_s.
Properly implement div* and implement rem. Div* needs
to use the y register, and rem* needs to be synthesized.
Correct b?sub* macro definitions.
* lib/jit_sparc-fpu.c: Correct reversed float to/from double
conversion.
Correct wrong jit_get_reg call asking for a gpr and then
using the fpr with that number.
Correct wrong branch displacement computation for
conditional branches.
* lib/jit_sparc.c: Correct getarg_d and pushargi_d implementation.
Add rem* entries to the switch converting IR to machine code.
* lib/lightning.c: Correct a problem detected when adding
the jit_class_nospill flag to jit_get_reg, that was caused
when having a branch to an "epilog" node, what would cause
the code to think all registers in unknown state were live,
while in truth, all registers in unknown state in the
"just after return" point are actually dead.
* include/lightning/jit_sparc.h, lib/jit_sparc-cpu.c,
lib/jit_sparc-fpu.c, lib/jit_sparc.c: New files implementing
the basic framework of the sparc port.
* configure.ac, include/lightning.h, include/lightning/Makefile.am,
include/lightning/jit_private.h, lib/jit_disasm.c: Update
for the sparc port framework.
* lib/jit_mips.c: Correct reversed retr/reti logic.
* lib/jit_ppc.c: Correct misspelled __LITTLE_ENDIAN.
* lib/lightning.c: Always do byte hashing in hash_data, because
the logic to "compress" strings causes large pointers to not
be guaranteed aligned at 4 byte boundaries.
Update for the sparc port framework.
