dd69694302 Add some optional logging to debug jit branching. 2013-01-20 19:48:55 -08:00
Unknown W. Brackets
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.

Log missed jit ops for poor man profiling

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.

862c88d61a More warning fixes, switches and printfs, etc. 
This time ones not reported by Visual Studio.

e78223d2c0 Since flipping the op is easy, also do lb/lh. 2013-01-19 16:25:57 -08:00

90e6f0b7df Optimize static memory read/writes in jit as well. 
Like the arm jit does.

bc75b68c36 Also jit sh and lhu, which are pretty common ops. 2013-01-18 23:10:51 -08:00
Unknown W. Brackets
d5ae85201c Optimize sw/lw even under safe memory. 
They're very common instructions, so shaving cycles helps.

11c5cdfdb0 Refactor out all the CheckJitBreakpoint()s. 
Ah, much cleaner.

5080285e54 Add breakpoints for delay slots. 
Wanted to do this in CompileAt(), darn not nice delay slots.

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.

a9293c8923 Add breakpoints to x86 jit for easier debugging. 
They should be really fast so leaving them on in release.

5552f93fca Fixes for Qt, Symbian and Blackberry. Reorder and remove some redundant ArmEmitter includes so that _SP doesn't conflict. 2013-01-17 11:00:07 +10:00

74cce1439b Allow downcount to be negative. 
This fixes threads/alarm/alarm and ctrl/sampling2/sampling2, which were
broken in 674911dd.

The downcount can go negative for a few reasons, and was signed before.

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