Although it's not clear what the xA and xB conditions are intended to do, the pattern indicates that xB is the regular version and xA is the inverted version, so for consistency, IsConditionB should be the main function.
Since the merge of b24b79e, we've gotten reports that the
following games are broken on JitArm64:
* Sonic Heroes
* The SpongeBob SquarePants Movie
* Astérix & Obélix XXL
* The Incredibles: Rise of the Underminer
Disabling the register cache avoids the issue, so the cause
of the bug might not actually have anything to do with the
newly implemented instructions. Nevertheless, I don't want
to ship a beta with this problem present, so I would like to
disable these instructions for the time being.
Hardware testing indicated that SRS uses a different list of registers than LRS (specifically, acS.h can be used with SRSH but not LRS, and SRS does not support AX registers, and there are 2 encodings that do nothing).
* DSP*Arithmetic: Fix grammar for ANDCF and ANDF
* DSP*Arithmetic: Fix registers used by MOVAX and MOV
* DSP*Branch: Fix documentation for JMPR
* DSP*Branch: Fix HALT encoding ("I think I saw a two")
* DSP*ExtOps: Fix 'LN encoding (The listed encoding was for 'L)
* DSP*ExtOps: Improve documentation for 'LD and 'LDAX
* DSPJitExtOps: Correct typo
* DSP*LoadStore: Remove obsolete comment about pc in SRS (This was fixed in 1419e7e5b2d8aad63ef9c2bf3ef9f5b7db759b49)
* DSP*LoadStore: Fix comments for LRR/SRR
* DSP*Misc: Improve documentation for SBCLR and SBSET
* DSP*Multiplier: Fix MULXAC encoding (The previous encoding was for MULXMVZ)
* DSP*Multiplier: Fix tabs in MULCAC and MULCMVZ (There are some other tabs in comments in the JIT, but these are the only ones that are in instruction comments instead of indicating the corresponding interpreter code. Those other comments can be corrected in a different PR, as they're not documentation related.)
* DSPJitMultiplier: Fix MULXMVZ typo
These instructions were already implememented by Dolphin, but never added to the manual. Extension instructions will be handled in a later commit, as wlil instructions that were not previously implememented by Dolphin.
The extension needs to happen in SetLongAcc, not GetLongAcc, as the extension needs to always be reflected in acS.h.
There is no functional difference with the write handler for acS.h, but it is more readable than 4 casts in a row.
`IsLess` would incorrectly return true if both `SR_OVERFLOW` and `SR_SIGN` are set, as `(sr & SR_OVERFLOW) != (sr & SR_SIGN)` becomes `SR_OVERFLOW != SR_SIGN` which is true as the two masks are different. This broke in e651592ef56521f6db71f8a671fe8c20b948d338.
This issue only affected the DSP LLE Interpreter, and not the DSP LLE JIT.
I've also included a simple test case for this. `ax0.l` (on the top left) is set to 0 if the instruction following `IFL` does not execute and to 1 if it is executed.
Retail-signed discs use the format: IOS56-64-v5661.wad
Debug-signed discs use the format: firmware.64.56.22.29.wad
Debug-signed discs usually have a 128 version of the firmware as well,
since some devkits have 128 MB MEM2. (Retail has 64 MB.)
