the & 0xFFC was missing, which caused it to return true when it should
have returned false. This means that LLE audio should be more optimized
now.
I also made it do delay slot, incase the delay slot instruction writes
to accumulator. Minor optimization here.
As for JAL, I made it do break instead of return FALSE because in Battle
For Naboo, it actually does come back and continue an existing
calculation. I think it is only an issue if you do a separate analysis
for the Low Accumulator and Mid/High Accumulators. It's still better to
be safe, just incase I or someone else actually implement a separate
analysis for the Accumulators later down the road.
I previously made a commit to fix a reordering issue, but did not
realize it needed that COPO_MF_Instruction flag for branching. This
should fix the Ogre Battle issue.
It's supposed to check the next instruction, which is PC, rather than
the current instruction which is CompilePC. This mistake is what caused
graphical errors in RE2.
Instruction Reordering broke Mia Hamm and possibly other games too. The
easiest way to fix the problem was to simply disable reordering for
specific cases that were never accounted for.
Not only were certain instructions missing, but also some were in the
wrong place or had the wrong attributes.
Also VSUB needed to be added to IsNextInstructionMmx.
I have only seen the edgecase for SQV happen when
IsRegConst(RSPOpC.base) == TRUE. Changing SQV fixed Telefoot / Mia Ham.
I optimized VAND, for games like Kirby64.
The possibility of the RSP instruction at address 0xFFC being JR was
never accounted for. This fixes Wave Race and Star Wars - Shadow of the
Empire.
The accumulator analysis was wrong, which broke games like Mario No
Photopie.
