Unknown W. Brackets 01aebe54b9 interp: Correct vdet prefix handling. 2019-03-31 15:01:11 -07:00
Unknown W. Brackets cc58d0d3a3 interp: Correct prefixes in vsrt ops. 2019-03-31 15:00:12 -07:00
Unknown W. Brackets 5736b1be2a interp: Correct some negative invalid zero cases. 
In these cases, the input value wires to +0.  Also, transposed the values
in a comment (oops.)
 2019-03-31 13:45:37 -07:00
Unknown W. Brackets aa998b815c interp: Force vscmp result of invalid to zero. 
Some other ops do this, but mostly only that do plus or minus.
 2019-03-31 13:41:48 -07:00
Unknown W. Brackets 5749ae09d0 interp: Correct vmfvc register behavior. 
The target and source registers were completely wrong.
 2019-03-31 13:41:48 -07:00
Unknown W. Brackets b2e024025f interp: Handle wrong sizes of vf2h/vh2f. 
Probably not ever used, but they have consistent behavior.
 2019-03-31 13:41:48 -07:00
Unknown W. Brackets aceb0a8244 interp: Correct vrnd prefix handling. 
We don't match random values perfectly anyway, but at least we should vary
at the right times.
 2019-03-31 13:41:48 -07:00
Unknown W. Brackets dfc2449f35 interp: Match actual vdiv prefix handling. 2019-03-31 13:41:48 -07:00
Unknown W. Brackets af3ed69144 interp: Mask moves to vfpu ctrl. 
These bits of the registers can't be written.
 2019-03-31 10:37:07 -07:00
Unknown W. Brackets 2a5d4e577d interp: Handle NAN more correctly in vscmp. 2019-03-31 10:37:07 -07:00
Unknown W. Brackets db28c61272 interp: Handle flush prefixes slightly better. 2019-03-31 10:37:07 -07:00
Unknown W. Brackets d40ac043d4 interp: Handle prefixes for Vmmov/Vmmul/Vmscl. 
I doubt any actual code uses this, but we have some tricky VFPU bugs left,
so just trying for maximum accuracy in the interpreter.
 2019-03-31 10:37:07 -07:00
Unknown W. Brackets 26b1368f7b interp: Handle vrot prefixes mostly correctly. 
Still some issues with 1/2 results and negate on swizzle.
 2019-03-31 10:37:07 -07:00
Unknown W. Brackets 8fd8dce185 interp: Use a helper to generate prefix consts. 
This makes more logical sense that using the VFPU_SWIZZLE and VFPU_ABS
macros to select the constant, although that's how the bits work.
 2019-03-31 10:33:26 -07:00
Unknown W. Brackets b86a6af364 interp: Properly apply mask on single lane ops. 
When using something like vadd.s, we should still be applying the mask.
Mainly should only matter if masks are set in a conditional, or if games
nop out instructions.
 2019-03-31 10:13:28 -07:00
Unknown W. Brackets 1936e8c4d1 interp: Generate constants using prefixes. 
This way they properly respect negate in the S prefix.
 2019-03-31 10:13:28 -07:00
Unknown W. Brackets 0be3213151 interp: Correct vscl prefix handling. 2019-03-31 10:13:28 -07:00
Unknown W. Brackets ec1dae57eb interp: Fix vbfy prefix handling. 2019-03-31 10:09:18 -07:00
Unknown W. Brackets d5273f589a interp: Mask value in vpfxd. 
The actual register ends up with only the lower 12 bits, which makes sense
since those are the only ones that do anything.
 2019-03-31 08:23:36 -07:00
Unknown W. Brackets 9d1d4473e8 interp: Confirm vi2f/vf2i prefix handling. 2019-03-31 08:22:52 -07:00
Unknown W. Brackets 30223cb17f interp: Apply T prefix to D in vcmov. 2019-03-31 08:22:15 -07:00
Unknown W. Brackets cfab70f149 interp: Handle abs/neg on nan values better. 
`fabsf` was altering other bits.
 2019-03-31 08:18:49 -07:00
Unknown W. Brackets aff1d8e8b2 interp: Implement vsbz and vlgb. 
Not sure any games actually use them, but good to have the remaining vfpu
ops all implemented.
 2019-02-23 15:08:49 -08:00
Unknown W. Brackets 179ec61815 interp: Correctly handle vsocp prefixes. 
Very similar to vsop, just with a bit more fixed values.
 2019-02-23 10:05:13 -08:00
Unknown W. Brackets 6178a1fb33 Jit: Correct vocp prefix handling. 
See #5549.  Matches tests for various prefix settings.
 2019-02-23 09:15:26 -08:00
Unknown W. Brackets d7f40afd9d interp: Correct vocp prefix handling. 
Also, guess that vsocp also applies prefixes.  See #5549.

Henrik Rydgard e3a81f4346 x86 Jit: Basic implementation of vbfy1/2 (mostly to just cross another one off the list..) 2014-12-04 00:18:58 +01:00
Unknown W. Brackets 316e923b40 x86jit: Implement other forms of vx2i. 
Gains 3.2% performance in Grand Knights History.
 2014-11-08 00:39:40 -08:00
Unknown W. Brackets fd1b01b573 Fix the vrndi.s output range. 
Was previously outputting only valid positive float values, but should use
a much wider range of a u32.

Might've affected randomness in some games.
 2014-09-01 22:33:01 -07:00
Unknown W. Brackets 252100aee5 Remove outdated comment (real cause found/fixed.) 2014-06-28 16:06:10 -07:00
Unknown W. Brackets 62daf6d7c8 armjit: Fix vmin/vmax to follow the PSP's rules. 
Also the interpreter.  Fixes #6107.
 2014-06-20 23:55:33 -07:00
Henrik Rydgard 0879d76503 VFPU: Ensure that sin(4*x) returns 0.0 (and cos 1) for all x. Fixes #2921 2014-06-15 11:03:00 +02:00
Unknown W. Brackets 69b0b622be armjit: Fix D-prefix sat clamp NAN handling. 
They should leave NAN alone.
 2014-05-16 01:04:57 -07:00
Unknown W. Brackets a3ad238a44 Add notes for proper NaN handling in vmin/vmax. 2014-05-16 01:04:56 -07:00
Henrik Rydgard c80510fb3b MemMap should not be included in MIPS.h. 2014-03-15 10:45:39 +01:00
lioncash b9886942a7 Fix some vertical alignments in misc Core source files. 2014-03-03 11:16:53 -05:00
Unknown W. Brackets 61d4e2196e Simplify vwbn.s slightly. 2014-02-16 00:00:29 -08:00
Unknown W. Brackets 34c6530b21 Implement vwbn.s, not sure what it's doing... 
This passes all the tests I could throw at it.  Fixes #1849.
 2014-02-15 23:51:41 -08:00
Unknown W. Brackets 3714fabad6 Implement vsbn.s, fixes #3409. 
Not sure if .q, etc. can work - won't compile, and I doubt any games try
it.  Just tried a basic implementation with reporting.
 2014-02-15 21:40:13 -08:00
Unknown W. Brackets ec05146ffd Improve vfpu disasm for a few instructions. 2013-11-29 10:07:15 -08:00
Henrik Rydgard 55500d4bb6 Reorder VFPU registers in memory so that we can flush and reload them in bulk more often. 
Doesn't actually do that yet, that's for the NEON branch.
