313ffdb495 Add a stub for clz/clo in x86 jit. 2013-02-21 01:25:02 -08:00

2db368c29a Add more imm handling for shifts in x86 jit.
This is actually hit, and propagates more imms through.

a438791e7c Initial (very inefficient) vmmov for x86 jit.
This makes #464 work (at least LittleBigPlanet), but only in x86 jit.

b8e2177591 Jit vzero/vone, which are easy and common (x86.) 2013-02-18 22:15:47 -08:00

2dfdf3ffeb Implement Comp_VV2Op vfpu ops in the x86 jit.
Also, some cleanup.  No need for this extra boilerplate, simplify...

This makes the Bink video issue slightly better, in jit only.

afb7c0b83c Assume prefixes start default until proven wrong.
Currently this means nothing since the MIPSTables flags are wrong.
It will blow the cache once, after the first vfpu op.

8ea59990ab Make applying prefixes mostly automatic.
And implement (hopefully) D prefixes.

27942606ad Use prefixD directly in jit, just like interp now. 2013-02-17 22:46:34 -08:00

f532951331 Automatically eat prefixes in x86 jit.
Simplifies the code and makes it easier to know they're eaten
even for ops not yet jitted.

f777c872e6 Jit unaligned reads/writes.
This mostly just improves perf on debug, not really on the map for release.

44b5adeaac Properly jit the break instruction.
Otherwise, it just keeps on going past it.
We never want to hit this anyway, but it's good to know if we do.

It's nothing to do with writing.

2eba209f64 Move around the jit nice delay slot logic.
Nice delay slots don't not save flags, they run before the CMP.

a9d0390426 Adjust downcount before syscalls, not after.
This makes jit slightly slower for syscalls, but it's minor and makes
sure jit and interpreter timing are determistically the same.

beac991a9e Clear jit cache when changing breakpoints.
For now, only when paused.  I don't think clearing the cache while
running is an awesome idea.

674911ddba Move downcount into MIPSState for efficiency, enable block linking.
On ARM JIT we can now reach it through the cpu context reg.
