Allow parallel compilation of SPU code, both at startup and runtime
Remove 'SPU Shared Runtime' option (it became obsolete)
Refactor spu_runtime class (now is common for ASMJIT and LLVM)
Implement SPU ubertrampoline generation in raw assembly (LLVM)
Minor improvement of balanced_wait_until<> and balanced_awaken<>
Make JIT MemoryManager2 shared (global)
Fix wrong assertion in cond_variable
* Fix SPU LR event setting in atomic commands according to hw test
* MFC: increment timestamp for PUT cmd in non-tsx path
* MFC: fix reservation lost test on non-tsx path in regard to the lock bit
* Reservation notification moved out of writer_lock scope to reduce its lifetime
* Use passive_lock/unlock in ppu atomic inctrustions to reduce redundancy
* Lock only once for dma transfers (non-TSX)
* Don't use RDTSC in reservation update logic
* Remove MFC cmd args passing to process_mfc_cmd
* Reorder check_state cpu_flag::memory check for faster unlocking
* Specialization for 128-byte data copy in SPU dma transfers
* Implement memory range locks and isolate PPU and SPU passive lock logic
Increase untouched buffer timeout when some of the buffers have been
touched. Might improve audio quality on games that suffered from
miniscule popping even when buffering was enabled (such as DeS).
In addition, made time stretching algorithm slightly more aggressive.
Includes some other tiny tweaks as well.
Also renames "AudioThread" to "AudioBackend". The new name is more
descriptive of what the class really is responsible for, since the
backends are not responsible for managing the audio thread.
NOTE: Right now only XAudio2 is supported
- Avoid tagging and rely on read/write barriers and the dirty flag mechanism. Testing is done with a weak 8-byte memory test
- Introducing new data when tagging breaks applications with race conditions where tags can overwrite flushed data
