* 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.
* 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.
* 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.
* 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.

* lib/jit_x86-cpu.c, lib/jit_x86-sse.c, lib/jit_x86-x87.c:
Actually change copyright owner to FSF as avertised.
* lib/jit_arm-cpu.c, lib/jit_arm-swf.c,
lib/jit_arm-vfp.c, lib/jit_arm.c,
lib/jit_mips-cpu.c, lib/jit_mips-fpu.c, lib/jit_mips.c,
lib/jit_ppc-cpu.c, lib/jit_ppc-fpu.c, lib/jit_ppc.c: New
files implementing initial code different jit backends.
* 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.
