- Added a LLVM SPU recompiler implementation as LLVM can't take advantage of the rounding mode.
- Further optimized the method by replacing MSB check with saturation subtraction. Negative values are saturated to zero due to the float's sign bit.
Removed the SSE4.1 instruction to make it compatible with the baseline instruction set. Increased dependency chain by one instruction and caused constant generation to be slightly more expensive.
Closes#18856
Moved the three download database actions from the game list context
menu to Manage -> Databases submenu, since they are not related to a
specific game entry.
The "Dirty hack for sound" in AudioSetNotifyEventQueue() is gated on a
named constant c_mxr000 that is supposed to equal the IPC key of the
_mxr000 event queue created by the game's _cellsurMixerMain thread
(0x8000cafe02460300, e.g. Virtua Fighter 5 FS / SEGA AM2 CRI titles).
When the inline literal was refactored into the named constant in
730badd37 ("cellAudio: Move and partially fix _mxr000 hack", 2023) a
trailing hex digit was dropped: 0x8000cafe0246030 instead of
0x8000cafe02460300 (the value used by the original 2018 hack in
cc0d7c598). As a result `key == c_mxr000` never matches and
lv2_event_queue::find(c_mxr000) looks up the wrong key, so the
surmixer-queue serialization path is effectively dead for every
_mxr000 CRI game.
Restore the correct 16-digit key so the gate and lookup match the
queue the game actually creates.
Note: this corrects a real latent bug but does not by itself resolve
the cellSurMixer null-deref in VF5FS (#17066), which is a separate,
flaky CRI channel-strip init divergence.
