easier to understand what data is available during
jit runtime.

* 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.
*include/lightning.h, lib/lightning.c: Add the new jit_live code
to explicitly mark a register as live. It is required to avoid
assuming functions always return a value in the gpr and fpr return
register, and to avoid the need of some very specialized codes
that vary too much from backend to backend, to instruct the
optimization code the return register is live.
* lib/jit_arm.c, lib/jit_mips.c, lib/jit_ppc.c, lib/jit_print.c,
lib/jit_x86.c: Update for the new jit_live code.

Implement the new qmul and qdiv instructions that return signed
and unsigned lo/hi multiplication result and div/rem division result.
These should be useful for jit translation of code that needs to
know if a multiplication overflows (no branch opcode added) or if
a division is exact (easy check if remainder is zero).

lib/jit_mips.c, lib/jit_note.c, lib/jit_ppc.c, lib/jit_print.c,
lib/jit_x86.c, lib/lightning.c: Extend the "jit_note" abstraction
with the new "jit_name" call, that receives a string argument, and
should usually be called to mark boundaries of functions of code
generating jit (that is, it is not expected that the language
generating jit map its functions to jit functions).
* lib/jit_note.c: New file implementing a simple string+integer
annotation, that should be used to map filename and line number
to offsets in the generated jit.
* include/lightning.h, lib/lightning.c: Update for the new
note code.
Add an extra mandatory argument to init_jit, that is used
as argument to bfd_openr.
Change from generic void* to char* the argument to jit_note
and add an extra integer argument, to map to filename and
line number.

lib/jit_arm.c, lib/jit_disasm.c, lib/jit_mips.c, lib/jit_ppc.c,

new annotation code.
* configure.ac, check/Makefile.am: Update to work with latest
automake.
* check/cccall.c, check/ccall.ok: New test case to validate
interleaved calls from/to C code and jit.
* check/Makefile.am: Update for the new ccall test case.
* include/lightning.h, lib/lightning.c: Add the new jit_address
call that returns the real/final address of a "note" in the
generated jit. It requires a jit_node_t as returned by the
jit_note call, and is only valid after calling jit_emit.
Add an intermediate solution to properly handle arm
soft and softfp modes that move a double to an integer register
pair. Currently it just adds extra tests for the condition,
but the proper solution should be to have extra lightning
codes for these conditions, codes which should be only used
by the backends that need it, and merged with the existing
jit_pusharg*_{f,d}.
* include/lightning/jit_private.h: Add new jit_state_t flag
to know it finished jit_emit, so that calls to jit_address
are valid.
* lib/jit_mips.c: Correct abi implementation so that the
new ccall test case pass. Major problem was using
_jit->function.self.arg{i,f} as boolean values, but that
would cause lightning.c:patch_registers() to incorrectly
assume only one register was used as argument when calling
jit_regarg_p(); _jit->function.self.arg{i,f} must be the
number of registers used as arguments (in all backends).
* lib/jit_x86.c: Add workaround, by marking %rax as used,
to a special condition, when running out of registers and the
allocator trying to spill and reload %rax, but %rax was used
as a pointer to a function, what would cause the reload to
destroy the return value. This condition can be better
generalized, but the current solution is good enough.
* include/lightning/jit_ppc.h, lib/jit_ppc-cpu.c, lib/jit_ppc.c:
Rewrite logic to handle arguments, as the original code was
written based on a SysV pdf about the generic powerpc ABI,
what did "invent" a new abi for the previous test cases, but
failed in the new ccall test in Darwin PPC. Now it properly
handles 13 float registers for arguments, as well as proper
computation of stack offsets when running out of registers
for arguments.

lib/jit_mips.c, lib/jit_ppc.c, lib/jit_print.c, lib/jit_x86.c,
lib/lightning.c: Change return value of jit_arg{,_f,_d} to
a jit_node_t* object, that should be used as argument to
jit_getarg_{c,uc,s,us,i,ui,l,f,d}. This just requires changing
from jit_int32_t to jit_pointer_t (or jit_node_t*) the "handle"
for the getarg calls, with the benefit that it makes it easy
to implement patching of the stack address of non register
arguments, this way allowing to implement variable size stack
frames if applicable; useful if there are too many registers and
jit functions uses only a few callee save registers.
* include/lightning/jit_ppc.h: Correct mismatch of JIT_F{1,5}
with enum codes, that were correct, and returned by jit_f().
* lib/jit_ppc-cpu.c, lib/jit_ppc-fpu.c, lib/jit_ppc.c: Properly
implement and better describe values when generating stack
frames.
* check/stack.ok, check/stack.tst: New files to test data
integrity on a deep chain of stack frames.

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.

addition of jit_ellipsis.
* lib/jit_ppc-cpu.c: Make movr a function that checks arguments
so that other code can safely assume it is a noop if src and dst
are the same register.
Implement rem{r,i}{,_u} as a div{,u}/mul/sub.
Correct ANDIS, ORIS and XORIS calls to cast the argument to
unsigned before the shift to avoid an assertion if the argument
had the topmost bit set.
Implement lshi, rshi and rshi_u as functions to test for a
zero argument, that would otherwise trigger an assertion when
computing the shift value.
Do a simple implementation of bm{s,c}{r,i} with a temporary,
"andr" of arguments and jump based on comparison with zero.
Correct typo in ldxi_c.
* lib/jit_ppc-fpu.c: Correct wrong arguments to FDIV* and STF*.
* lib/jit_ppc.c: Correct wrong check for 6 instead of 8 integer
arguments in registers. If calling a varargs function and
passing a float or double argument, also either store the
value in the stack or in integer registers, as varargs functions
do not fetch it from float registers.
Add "case" for new functions and incorrectly missing ones.
Call libgcc's __clear_cache, that should know what to do
if the hardware needs flushing cache before execution.
* lib/lightning.c: Do a simple/trivial logic in jit_regset_scan1,
that should make it easier for the compiler to optimize it, and
that also corrects the previously wrong code for big endian, and
that was causing problems in ppc due to not saving all callee save
registers as it was not "finding" them in the regset due to the
little endian assumption bug.
* 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.
* lib/jit_ppc.c: Assign copyright ownership to FSF.
* lib/jit_x86-cpu.c: Correct integer multiplication that was
generating code with reversed register arguments.
