d1909a1581 Add a quick disable define for nice delay slots. 2013-01-24 19:11:03 -08:00
Unknown W. Brackets
75cbe18afc Simplify nice delay slot detect, and yes for noop. 
NOOP seems very common so this should already benefit speed a bit.

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

3444fc8981 Avoid some memory writes on jr. 
Should improve tight mips function loops a bit.

c324983340 Make the jit support bltzal and friends. 
Fixes problems with jit in games.  Android changes completely untested.

de2df87758 Make interpreter call Advance() the same as jit. 
Probably makes more sense anyway, since the first events will be
more correctly timed, like savestates, sound, etc.
 2013-01-21 23:16:23 -08:00
Unknown W. Brackets
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.

566b7a0910 A branch was missing inDelaySlot, refactor it. 2013-01-21 22:45:07 -08:00

c897e6446a Don't over decr downcount when hitting a jit bp. 2013-01-21 19:41:12 -08:00

d99d060c2e Decrement downcount in skipped likely slots. 
Pretty sure this is right, it eats up a cycle as a nop.

Also some funny indentation.

8438371941 Read memory in the jit dispatcher same as lw. 
Just for consistency.  One less op, maybe faster, probably same.

4c271fc09e Add DELAYSLOT and LIKELU flags to some ops. 
Should improve cycle estimate, and makes analysis easier.

e8dc99328a Avoid using EAX as a temporary where possible. 
All the regs should be indirect addressing compatible.  So if it's
in a reg, let's use that instead of EAX.

53600161ba Don't write anything to a bad static pointer. 
Not sure what came over me...

385417effe Log jit misses at runtime instead of compile time. 
Really, it could be very different after all... this shouldn't be
all that slow, I guess.
