* lightning/i386/core.h: Use jit_save in jit_replace. Move JIT_R
definition...
* lightning/i386/core-32.h: ... here; define jit_save so that
the core.h has no effect on the 32-bit backend.
* lightning/i386/core-64.h: Place JIT_R1/JIT_R2 in R10/R11,
place outgoing arguments in the right spot from the beginning,
define jit_save, fix jit_reg8/jit_reg16.
2008-06-14 Laurent Michel <ldm@thorgal.homelinux.org>
* lightning/i386/core-64.h (jit_movi_l): When the operand is 0,
the XOR should be on a quadword.
* lightning/i386/core-64.h (jit_prolog): Keep 16-byte stack
alignment.
(jit_ret): Always use LEAVE.
2008-06-13 Laurent Michel <ldm@thorgal.homelinux.org>
* lightning/i386/core-64.h: Add (void) casts for C++ compatibility.

2008-06-12 Paolo Bonzini <bonzini@gnu.org>
* lightning/i386/core.h: Move JIT_V definition...
* lightning/i386/core-32.h: ... here.
* lightning/i386/core-64.h: ... and here. Avoid dancing between
RSI/RDI and R12/R13, and place JIT_V1/JIT_V2 in R12/R13.

prolog/ret macros. Subtract 12 bytes in __APPLE__ case to
keep stack aligned, and always use LEAVE in the epilog.
2008-03-21 Paolo Bonzini <bonzini@gnu.org>

2006-11-04 Paolo Bonzini <bonzini@gnu.org>
* lightning/ppc/core.h: Implement jit_allocai, define JIT_FP to be R1.
* lightning/ppc/funcs.h: Store frame size into _jitl. Store R1 before
the STMW, so that the offset is unchanged when we patch the STMW.
* lightning/i386/core.h: Define JIT_FP to be EBP.
* lightning/i386/core-32.h: Implement jit_allocai, put LEAVE in the
epilog if jit_allocai was used.

2006-11-03 Paolo Bonzini <bonzini@gnu.org>
* lightning/ppc/core.h: Fix jit_bms using BNE rather than BGT.
"AND." does signed comparisons.

* lightning/sparc/core.h: Fix bugs in modi/divi.
Patches applied:
* lcourtes@laas.fr--2005-libre/lightning--stable--1.2--patch-11
Fixed a typo in `lightning/sparc/core.h'.

SPARC: Fixed `jit_immsize' (untested!).
* lcourtes@laas.fr--2005-libre/lightning--stable--1.2--patch-13
Added a `divi' test case (does not catch the bug fixed by the previous patch).
* lcourtes@laas.fr--2005-libre/lightning--stable--1.2--patch-14
`divi' test case: Return non-zero on failure.
* lcourtes@laas.fr--2005-libre/lightning--stable--1.2--patch-15
`ldxi.c' (test case): Make sure we use a large pointer operand.
* lcourtes@laas.fr--2005-libre/lightning--stable--1.2--patch-16
Added a `movi' test case (for `jit_movi_p' with large operands).
