* lib/jit_arm.c, lib/jit_mips-cpu.c, lib/jit_mips.c: Correct
regressions when patching jit_calli for a forward function.
* lib/jit_ppc-cpu.c: Correct wrong arguments to ANDI opcode
in jit_getarg_u{c,s} implementation.
* 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.
* include/lightning.h, include/lightning/jit_private.h,
lib/jit_arm.c, lib/jit_mips.c, lib/jit_ppc.c, lib/jit_x86.c,
lib/lightning.c: Make jit_ellipsis implementation not
backend specific. It is not intended to handle va_list
like objects at runtime, as jit_arg* and jit_getarg*
return constant values resolved at parse time, so, effectively
it is not possible to create printf like jit functions, as
there is no va_start, va_arg, va_end, etc, abstraction. This
limitation should be kept for the sake of making new ports
easier.
* include/lightning.h, lib/jit_arm.c, lib/jit_mips.c,
lib/jit_ppc.c, lib/jit_x86.c, lib/lightning.c: Change jit_prepare
to no longer receive an argument. If receiving an argument, it
should be an ABI specifier, not a boolean if varargs or not,
and add the new jit_ellipsis call, to specify where the
ellipsis is in the C prototype of the function being called.
Note that currently it is not supported to define varargs
functions and it will be ignored if calling jit_ellipsis not
in a prepare/finish* block, but this should be addressed.
* check/allocai.tst, check/alu_add.tst, check/alu_and.tst,
check/alu_com.tst, check/alu_div.tst, check/alu_lsh.tst,
check/alu_mul.tst, check/alu_neg.tst, check/alu_or.tst,
check/alu_rem.tst, check/alu_rsh.tst, check/alu_sub.tst,

check/ldstr.tst, check/ldstxi-c.tst, check/ldstxi.tst,
check/ldstxr-c.tst, check/ldstxr.tst, check/rpn.tst,
check/lightning.c: Update for the change to jit_prepare and
addition of jit_ellipsis.
* lib/jit_mips-fpu.c, lib/jit_mips.c: Implement missing mips
jit_sqrtr_{f,d} codes.
* check/all.tst, include/lightning.h, lib/jit_print.c: Change
declaration order and call order in all.tst of {add,sub}c and
{add,sub}x. *c must be called before to set the carry and *x
second to use the carry and keep it set. The wrong call order
was causing all.tst to fail in mips, where a register is
allocated to keep a global carry state.
* 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.
* include/lightning/jit_mips.h, lib/jit_mips.c: Update to
make the mips backend compile in a qemu image.
* lib/jit_ppc.c: Minor adaptations to help in having the
ppc backend compilable.
* 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.
