Henrik Rydgård 7fbe8ba898 Merge pull request #7076 from unknownbrackets/debugger 
Add VFPU instructions to the mips asm tables
 2014-11-10 00:57:08 +01:00
Unknown W. Brackets 370fb86379 Add VFPU instructions to the mips asm tables. 2014-11-09 15:14:07 -08:00
Unknown W. Brackets 86e3739a3e x86jit: Optimize some cases of ins/ext. 
They happen but are minor.

Unknown W. Brackets e05263af32 x86jit: Allow EBX sign extension for 32-bit. 2014-11-09 09:07:52 -08:00
Unknown W. Brackets 8dbd3c3b9c x86jit: Don't lie about ZERO when it's not an imm. 2014-11-09 08:27:02 -08:00
Unknown W. Brackets d0a2ced2f9 x86jit: Flip cc in stl* to avoid reg loads. 
Unfortunately, this zero thing is now concerning me...
 2014-11-09 08:15:39 -08:00
Unknown W. Brackets 59f491eddb x86jit: Micro optimize slt* a bit. 
This improves their performance and hopefully latency.  It also avoids
filling registers that are not likely to be used again.

Fixed a small mistake.

Broke a lot of games, probably some small bug.

Unknown W. Brackets 7d8858687e x86jit: Avoid speculative loads in mtc1/mfc1. 2014-11-08 18:35:15 -08:00
Unknown W. Brackets 57caa95273 x86jit: Implement round.w.s and friends. 
They are not terribly fast, though, updating MXCSR.
 2014-11-08 17:59:38 -08:00
Unknown W. Brackets 3908e0f445 x86jit: Small optimization for add.s f1, f2, f2. 
Doubles the speed of that particular case.  Biggest difference is not
loading fd for no reason.
 2014-11-08 17:32:53 -08:00
Unknown W. Brackets f9893c29ce x86jit: Very small optimization to c.nge.s. 2014-11-08 17:01:02 -08:00
Unknown W. Brackets 78dfe43776 x86jit: Optimize neg.s and abs.s a tiny bit. 
Same reg is probably a common case, improves micro benchmark.
 2014-11-08 16:50:41 -08:00
Unknown W. Brackets bed0d0b059 x86jit: Improve cvt.w.s when fd is loaded or fs. 
We have no need to store it.
 2014-11-08 16:40:54 -08:00
Unknown W. Brackets 1917d946ea x86jit: Micro optimize cvt.s.w a bit. 
This implementation is about 5x faster for micro benchmarks.  Little
impact to overall perf in games I tested, though.
 2014-11-08 13:30:38 -08:00
Unknown W. Brackets 671dee85c7 x86jit: Micro optimize vi2f a little bit. 
This didn't help overall perf much but micro benchmarks are better.

Unknown W. Brackets bc7497857a x86jit: Micro optimize vi2x a bit with ssse3/sse4. 
Both are small wins.
 2014-11-08 12:13:26 -08:00
Unknown W. Brackets 0e646f748a x86jit: Implement vi2x instructions. 
Also, my opcodes were wrong in the test (shifted the pair bit the wrong
way, oops.)

AFAICT, there's no reason PSRAD/etc. were not encoding REX...

This is not performance critical.  I wonder if compilers can inline
closures?

Unknown W. Brackets 5ef2df7ebd Fix a small warning on 32-bit. 
Would only practically matter for very very large reads on very very large
csos.

Unknown W. Brackets 3e95763a3f x86jit: Implement other rounding modes in vf2i. 
3% improvement in Grand Knights History.  I know other games use these
too.
 2014-11-03 23:27:05 -08:00
Unknown W. Brackets 717cf25f0d x86jit: Use our sincos funcs for VV2Op as well. 
Small (0.7%) speedup in Gods Eater Burst.  There's probably SSE
approximations we could use instead, but those will also need at least xmm
reg flushing/thunking.

At least this avoids flushing gprs, etc.  The sin and cos ops are fairly
common.
