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.

keyword "id" in the public auibar.h header.
You now need at least r66546 of wxWidgets to build on OS X.

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.

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

* Optimised out the R11 ImmPtr instructions
* Made the whitespacing a little more consistent
* Disabled block linking while it is being reworked

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.

* Fixed a bug in the JCC instruction.
* Changed the cycle count from u32 to u16.
* Added cycle counting to the block linker.
* Optimised the branch exit slightly.

(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)

* Completed the JIT versions of the DSP Multiplier instructions (5 instructions added).
* Bug fixed the dec and lsr16 instructions.
* Minor code clean-up.

* Completed the JIT versions of the DSP arithmetic instructions (28 instructions added).
* Added JIT versions of maddx and msubx (thanks to LM1234).
x64 only

* 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.
