dolphin/Source/Core/DSPCore/Src/DSPIntUtil.h, branch master

Core and DSPCore now have mutual dependencies, which breaks the

2011-01-29T14:06:48+00:00

assumption on the part of many linkers that static libraries make
up a DAG, so merge libdspcore into libcore.

LLE JIT:

2011-01-01T13:19:07+00:00

Applied the logic from r6691 to the LLE dec/add/sub functions so they work without ToMask. This should give a modest speedup for these.

Pierre's AR inc was already perfect and I only adjusted its logic a bit for visual consistency between the interpreter and JIT code.

Also applied Pierre's optimization from the LLE inc to the Int inc.

LLE Int: (addr add/sub/inc/dec)

2010-12-30T15:36:28+00:00

Adjusted the code work without ToMask.
This code should be functionally identical for all inputs to the previous code.

Core/DSPCore: Changed g_dsp._r back to g_dsp.r. Removed the check*Exclude

2010-12-29T20:20:52+00:00

functions accidentally added. Fixed the jitted ar register arithmetic.
Added a CMakeList.txt for the UnitTests, but did not add the subdirectory
to Source/CMakeLists.txt.

Core/DSPCore: Reorganize register layout for accessing accumulators

2010-12-29T02:12:06+00:00

(acc and ax) and product register with one read/write.

Gives a minuscule speedup of not more than 4%. In exchange, breaks all
your out-of-tree changes to dsp. Tests are not building again, yet.

Core/DSPCore: Improve Interpreter address register add/sub, convert to

2010-12-27T15:05:18+00:00

 assembler for JIT. Replace JIT ToMask() with a different variant. Remove
 superfluous zeroWriteBackLog calls(added by me).
Core/Common: Don't bother creating a string and calling into a Logs trigger()
 when there is noone listening. Change AtomicLoadAcquire for gcc to just
 make the compiler not reorder memory accesses around it instead of doing
 a full memory barrier, per the comment in the win32 variant.
Core/AudioCommon: Fix a use of uninitialized variable inside libalsa.

Microbenchmarking results for ToMask variants:(1 000 000 000 iterations):
             cpu\variant| shifts | bit scan
intel mobile C2D@2.5GHz | 5.5s   | 4.0s
amd athlon64x2@3GHz     | 6.1s   | 6.4s
(including some constant overhead identical to both variants)

DSPLLE-int AR increase, decrease finally 100% (code by kiesel-stein/dolphin-forum, great work btw!!)
