Eliminates Tekken 6 leg shaking.

13278dc1f4 interp: Implement software sqrt to match PSP. 
This matches the PSP's square root better.

Disabled by default using a compile-time flag.

ed4f0896db interp: Use vfpu_dot for vdet as well. 
Improves test accuracy here too.  Also keep neg sign on NAN for vdiv.

Disabled by default via compile-time flag.

4bff980d34 interp: Use software dot for better accuracy. 
This gets some vdot/similar tests to give more accurate results compared
to hardware.  Also added flushing of zero and NaNs.

Currently disabled, only enabled with a compile-time flag.

3cb1c33fd9 interp: Fix dumb mistake in vtfm. 
Had done final testing on this with a 2x2 matrix because it was simpler...

Fixes #12109.

89dbfd7d5b interp: Better prefixes for vdiv/similar ops. 
Turns out it does work, just uses the wrong slot like S/T after all.
These other ops must go through the a similar process.

85ff32eed1 interp: Handle vsgn prefixing. 
One could compare against 3 using this, it just generates zeros to compare
with.

b881a689c4 interp: Ignore high bit in vmfvc/vmtvc. 
Both 0 and 128 read/write the S prefix, for example.

dfd8094f21 interp: Implement vcrs prefixes and sizes. 
It only makes sense as triple, but it can be used as quad/single/etc. and
has consistent and sane results.

68cdcba6c5 interp: Don't write lane 2 on single colorconv. 
Not that it's valid to use the op with that size anyway.

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.)

aa998b815c interp: Force vscmp result of invalid to zero. 
Some other ops do this, but mostly only that do plus or minus.

5749ae09d0 interp: Correct vmfvc register behavior. 
The target and source registers were completely wrong.

b2e024025f interp: Handle wrong sizes of vf2h/vh2f. 
Probably not ever used, but they have consistent behavior.

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.

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.

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.

1936e8c4d1 interp: Generate constants using prefixes. 
This way they properly respect negate in the S prefix.
