0f32103615 x86jit: Consistently use mips_. 2014-10-12 15:16:09 -07:00

6fae78cd3f x86jit: Fix a bug in branch continuing. 
When we predict it won't take a likely delay slot, we'd lose our register
allocation state.

2f598e8f38 jit: Statically jump for fixed branches. 
This handles both loops (first step is known) and static branches (some
code uses them instead of jumps, and we disassemble that to "b".)

Not likely to be a big improvement, but might help if the branch predictor
was wrong.

This is as opposed to continuing, which would build a larger jit block.

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

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.

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

savedata.

1cb7965cb1 Jit feature preparation: Introduce "proxy blocks". 
When these are invalidated, the block they point to gets invalidated too.

Will be useful to implement various types of block merging and function inlining
without affecting correctness of cache clears etc.

Also, with this commit we can now fully inline replaced functions. fabsf() boils
down to 1-2 instructions and the block continues, for example.

Still doesn't seem to work.  Something like a 4% gain in Star Ocean was
the best I saw...

359110f010 x86/armjit: Add jump following (off by default.) 
Inlines function calls up to a certain extent.  Allows us to get
immediates all the way to a syscall, for example, usually.

Not sure if faster.

aacb31bc18 armjit: Copy over (disabled) immbranch optim. 
This does a little loop unrolling.  Costs a bit more cache space, but
avoids flushing regs for longer.

5a95e267fb Add an optimization to discard registers at the end of functions when possible. 
Works in some games but crashes many so hiding it for now. Do not add UI.

732ae13ebb Fast path CallSyscall where possible. 
It seems we're spending a decent amount of time there, which isn't
entirely unexpected.  We can eliminate some things easily.

Thanks go entirely to @Kingcom for pointing this out.

Don't know of any games not using RA as the rd.

6c97b66806 Cap imm branch instructions, reset compiling. 
Break and other delay slot ops could've set it to false.

It's actually sometimes faster now.

e639f8d15f Handle branches in VFPU delay slots better. 
Based on tests on a PSP, all branches are attempted.  The behavior is
technically undefined.

It seems to take the delay slot's target if they differ and both pass.
This is the behavior the interpreter has, but it's more work in jit.

Since only a couple games seem to do this, and clearly expect this
behavior, this fixes all known cases of #1926.
