87e1518e96 A few fixlets to the SIGSEGV library: 
- Don't export transfer types definitions (formerly used by older API)
- Handle ADD instructions in ix86_skip_instruction() (generated by icc 9.1)
- Use "%p" format for EIP/RIP addresses

c8a273332f Fix for 32-bit x86, was generating setcc CC,%dh instead of %dl. 
i.e. force use of ecx & edx -- though it was fine in 64-bit mode, of course

e07e2196e3 Use new code generator. The gain is only 10%, bottlenecks are elsewhere.

4e624209d3 Add new code generator for testing purposes (i386, x86_64) -- It's to be

c306dfc4fd Make VSCR an uint32, don't bother splitting it into NJ, SAT values since 
the gain is almost nil and actually hurts performance in JIT mode.

utils-sentinel.hpp for helper functions to be called at program initialization
and termination.

b4768fc62c Run-time assembler fixes: 
- Check for RIP register only in 64-bit mode
- Add missing macros and arguments (BT*im)
- MOVSWQ/MOVZWQ are 64-bit mode instructions only

5d7ef13a9c Fix gen_op_invoke*() for 64-bit offsets on x86-64. Drop CPUPARAM since it's 
now cached to a host register.

7d5898f97a Some minor optimizations: xchg (unused), movdqa in sse2 code. 2006-07-09 12:19:50 +00:00
gbeauche
abc911eaa7 Remove use of global register A0 (now aliased to T0). This makes it possible 
to cache the CPU context pointer to a register and thus rendering generated
code CPU context independent. Not useful to SheepShaver, but it is for
another project for threads emulation on plain x86-32.

Note: AltiVec performance may drop a little on x86 but this will be restored
(and even improved) in the future.

d0a64733ef Use -fno-align-functions to really disable function alignment (a value of 0 
used the default alignment, e.g. 16 bytes on x86_64). This is purely cosmetics
and only helps reading the resulting disassembly.

c677dff47a Add more micro asm optimisations to x86{,-64} (mulhw, mulhwu, slw, srw, cntlzw 
and subf* series). Also now enable the optimzations on x86_64 by default.

0123552ddc Use extra precision (e.g. long double) for fma operations though this 
inhibits some underflow conditions.

7efab4276f Improve FPU emulation accurracy. However, PPC_ENABLE_FPU_EXCEPTIONS is still 
set to 0 until generated code is optimized enough (current slow down factor
is 3x vs. previous core, expectations are about 50% slower FP code).

The main benefit is exception bits are accurate. All glibc test-fenv,
test-arith{,f}, test-double, test-float pass on ppc, and mostly on x86_64
with gcc 4.0.1. Yes, this is also compiler dependent.

FIXME: find a real Mac application that depends on precise FPSCR bits... I
think I don't want to care optimizing yet until someone shows me a real world
application.

dc88ee271d Use lrint() for fctiw on x86-64. This is because some glibc use AMD optimized 
math library where floor(), ceil() et al. don't set the inexact flag correctly
