stacks), addition of a register cache(currently accumulators on 64bit only).
It feels a bit slower, but the numbers are about the same.
Caching accumulators doesn't change speed either.

Also a small change to the mixer. This should fix audio throttling in cases where num_samples > RESERVED_SAMPLES. This seems to happen now with zelda ucode games, possibly others.

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.

* Optimised out the R11 ImmPtr instructions

Added a CMakeList.txt for the UnitTests, but did not add the subdirectory

(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.

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)

* Added 21 Arithmetic instructions to the JIT
* Used the DSPAnalyser to identify arithmetic/multiplier instructions that precede a conditional branch. This allows the JIT to skip updating the SR when nothing would read from it. Marked all arithmetic/multiplier instructions in the DSPTable for this purpose.
* Converted CheckExternalInterrupt into ASM
* Fixed a couple instructions in DSP Load/Store

* Added jit versions of 5 DSP LoadStore instructions: srs, lrs, lr, sr, si
* Renamed MainOpFallback to Default for consistency in naming with JIT64
* Made ext_dmem_read and ext_dmem_write more generic for wider use
* Optimised dmem_read and dmem_write slightly
* Added dmem_read_imm and dmem_write_imm optimised versions
git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@6596 8ced0084-cf51-0410-be5f-012b33b47a6e
* Optimised the updating of g_dsp.pc in the compile loop (code by kiesel-stein)
* Added JIT version of LRI (code by kiesel-stein)
* Added JIT versions of the branch instructions (code by Jack Frost)
* DSP_SendAIBuffer fix (code by Mylek)
* Marked instructions that update g_dsp.pc in the DSP table and updated PC based on the table (speed up)
* Fixed the signed bits not being set properly in the addr instruction
* Created a MainOpFallback function to use interpreted versions of the instructions if necessary (code by kiesel-stein)
* Disabled the jit versions of subarn and addarn as they are slowing down NSMBW
The above work in both x86 and x64 modes.

Most of the code dealing with the LogTypes namespace was C which lead to a
lot of nonsensical casting, so I have dumbed LOG_TYPE and LOG_LEVEL down to
plain C even though the move of wiiuse into Source means we don't currently
call GenericLog from C.
Set logging threshold to MAX_LOGLEVEL at startup so debug builds will also
p rint debugging messages before the GUI is running.
For some reason the way we use SetDefaultStyle doesn't play nice with wx 2.9
so we just get the default black text on a black background. Using a gray
background works around that problem, but I found it to also be much easier
on the eyes so I have switched the background color on all versions.

Also add the mask for ADPCM predictor, like r6480 does.
Tested 64 bit linux/windows. At least compiles for 32 bit windows, but
with these binaries most of my guest software fails with
DSPLLE(interpreted and jit) when it gets to do actual work.

zeroWriteBackLog() calls.

* Make writeToBackLog private to DSPIntExtOps.cpp
(JIT variants of 'l and 'ln are disabled and broken as is)
* Make zeroing of the backlog conditional on doing an interpreter fallback and
do it at a few more places
* Fix selection of cleanup for extended opcodes.
* Fix the DSP unit tests to correctly emit the function prolog/epilog
(else EBX wouldn't be saved)
* Add a few more DSP unit tests

IsSameMemArea check in the rest of the file.
Looks like this is simply a copy-paste error, that i dutifully "fixed" for 64 bits.
No idea if this fixes anything, but it brings JIT more in line with the interpreter.

This is the safe variant that does not assume other
functions use R11 for &g_dsp.r, which they actually do.
So there is a lot unnecessary reloading of the register
getting emitted.
There are a few small changes exploiting pointers known
at emission time and making use of MComplex math.
Also renames m_LLEplaying to m_AIplaying in Core/AudioCommon.

Someone might want to add it to the Unit test
