1064f580e4 armjit: Add proxy blocks for continuing. 2014-10-12 17:20:26 -07:00

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.

8daff0a25e armjit: Fix some downcount issues with rounding. 
When setting the rounding mode we need to be super careful about not
destroying flags or R0 if they are needed.

0078faef8b Fix some log semicolons that might affect logic. 
But, these should all be right.

5a89c17cf0 armjit: Allow R1 in regalloc, use LR as temp. 
LR should be safe, although it may make stack traces not work within jit,
they don't really tend to work anyway.

Especially templates.

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.

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.

Not enabled.

7e46ee0b0f armjit: Replace MOVI2R with using the regcache. 
So that it can optimize the value with existing imms.

Not actually optimizing yet.

b30928036e armjit: Avoid flushing an imm in beq/bne/etc. 
We might be able to STMIA it instead.

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.
