419c1fbd73 Jit: Respect flags for jit types and features. 
Left some free space for more.

ab809bd19e jit: Apply hasSetRounding at compile time. 
Otherwise, the block will be executed with the wrong rounding mode the
first time rounding is set.  This could be important if it was set for a
single operation.

This is only a problem the first time it's set.

8c3552de74 cmake: Detect features at compile time 
Instead of relying on manually passed down flags from CMake,
we now have ppsspp_config.h file to create the platform defines for us.
This improves support for multiplatform builds (such as iOS).

e58eb5e186 x86jit: Small optimization for fd->fd fp convert. 
We just generate a little less code.  This is also slightly faster
generally.

7e38df077f x86jit: Prefer MOVAPS over MOVSS for reg->reg. 2015-04-10 20:07:43 -07:00

9069c84928 x86jit: Use ANDPS for abs.s. 
Should be faster considering they're likely to use other floating point
math on it.  As long as that's the case, this is faster than PAND.

05a8e2e35d Some work towards being able to build two JITs together 
This will be useful for testing/debugging, but not there yet.

1c78e29c79 x86 jit: For clarity, use TEMPREG where it doesn't matter that it's EAX. 
Might have missed a few places.

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.

5888b3bdc4 Revert "x86jit: Micro optimize slt* a bit." 
This reverts commit ee66596b8d.

Broke a lot of games, probably some small bug.

57caa95273 x86jit: Implement round.w.s and friends. 
They are not terribly fast, though, updating MXCSR.

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.

78dfe43776 x86jit: Optimize neg.s and abs.s a tiny bit. 
Same reg is probably a common case, improves micro benchmark.

bed0d0b059 x86jit: Improve cvt.w.s when fd is loaded or fs. 
We have no need to store it.

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.

928e2adfc9 jit: Avoid applying/restoring the rounding mode. 
If the game never sets it, we can skip around syscalls, interpreter,
replacements, etc.

8d0dca71fe jit: Rename the rounding mode funcs to clarify. 
They apply/restore the value, set/clear is confusing.

52b6f1095e armjit: Fix rounding mode, allow non flush-to-zero. 
Default: force flush to zero (for RunFast mode.)  But now it's an ini
option so we can more easily compare armjit differences.

Unknown W. Brackets
925557ed47 x86jit: Maintain the rounding mode always. 
This should be less often than doing it per block that uses fpu, unless
the game doesn't use fpu much at all.

ab13b36484 x86jit: Implement cvt.w.s. 
Not really used that often, anyway, but easy enough and good for testing
that we set the rounding mode correctly.

dc91dc1ce8 x86jit: Support fpu rounding modes for mul, etc.

savedata.

acad2e1763 x86jit: Cache fpcond in a register.

6ccae8f5a7 x86jit: Use a faster safemem fallback. 
Really helps performance in games that use uncached addresses a lot,
without really impacting performance of most games which don't.

Of course, fastmem is faster.
