e07e2196e3 Use new code generator. The gain is only 10%, bottlenecks are elsewhere. 
Optimize Altivec vector splat instructions after Agner's guide.

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

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.

9bc307c3fd Fix for new code generator -- FIXME: backend macros should be enabled only

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

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

3f3891ab31 Move up NATMEM_OFFSET to 0x11000000. This is arbitrarily determined to be 
the base of the largest free block. Turns out SDL libraries are loaded around
0x10000000 so we have some luck here.

c5c748f7e2 Some windowed graphics drawing methods cause the snapshot code to fail 
if you have changed the depth since boot (seems to be something strange
with the parameters that I still haven't worked out). If this happens,
we now put a suggested workaround in the warning message.
