There were no other members of struct `tagOPCODE` besides one nameless union, so, to fix some nameless union compiler warnings, I deleted struct tagOPCODE and named the nameless union, union tagOPCODE. Since "OpCode.h" is #include'd 9 times across the RSP source, technically this commit fixes 9 warning messages, even though it's really just 1 warning.
It may be true that this SQV edge case only seems to happen when
isRegConst = true, I forgot to account for the possibility that GPR
Constant Analysis could be disabled.
I also just noticed that I goofed with the non-sse shuffling ;/ . The
registers weren't in order.
I totally forgot that LDV handles elements differently than SDV. I added
a fallback to deal with unusual elements and added an alert to notify
that it exists in a particular game. I removed the & 0xF since that's
not needed. My previous change caused Stunt Racer 64 to have audio
issues. It should now be fixed.
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.
Fixing SW allows a lot more games to work. Fixing LW fixes games like
WDC and improves performance somehow. Fixing VMRG fixes certain bugs,
like Kirby 64's intro.
Set bitmasks for two calculations in RSP_SW_DMEM, to stop errors in Banjo Kazooie when in debug mode for RSP. (Was attempting to cast to a smaller data type, causing a loss of data)
