490fa2d553 Add x86 asm opts (though disabled for now) 2003-12-03 11:45:45 +00:00
gbeauche
5b0569944f Don't enable asm opts for now, this hides measurability of other generic 
optimizations. Remove no longer used synthetic instructions.

04214f3820 Fix decrement the CTR, then branch conditional if decremented CTR != 0. 
Remove CR cache for now. Remove BC & MODE_68K hacks for SheepShaver,
that was a colateral damage of wrong branch emulation of the former.

687b9c5a74 I manually synchronize with Kheperix code. 2003-11-27 20:07:33 +00:00
gbeauche
aee3e05e4b The JIT should work now but there is an extra bottleneck causing it to 
not match Kheperix speeds while executing Linux/ppc binaries.

Fix x86 DYNGEN_OP_FLAGS settings. Only allocate translation cache in .data
on PPC since x86 can do jumps anywhere.

73d51962f6 Merge in-progress PowerPC "JIT1" engine for AMD64, IA-32, PPC. 
The merge probably got wrong as there are some problems probably due to the
experiment begining with CR deferred evaluation. With nbench/ppc, performance
improvement was around 2x. With nbench on x86, performance improvement was
around 4x on average.

Incompatible change: instr_info_t has a new field in the middle. But since
insertion of PPC_I(XXX) identifiers is auto-generated, there is no problem.

7968a20100 Handle "JIT1" engine but disable it for now since there are some problems 
with SheepShaver integration from Kheperix.
