c2bf09744a SoftGPU: Fix refactoring mistake where we could return an uninitialized value. Oops. 2023-09-15 10:01:28 +02:00

cd3fc26190 samplerjit: Prevent thread local stale cache read. 
If the generation count happens to match, would still get a stale pointer
and crash.  Let's just make the generation count static so it always
increases.

eda3ce556e softgpu: Avoid atomic structs. 
Apparently we don't link libatomic and rather than fighting that, I'll
just use thread local values.

400f6abf9a softgpu: Optimize lookup of last jit func. 
This is common (for example, maybe a pixel state is updated but sampler is
not), and reduces time spent in ComputeRasterizerState() quite a bit in
Darkstalkers, where jits are available (i.e. Intel currently.)

87fb9eef37 softgpu: Remove std::function usage. 
Wanted to avoid coupling these, but don't like the std::function
construct/destructs showing in profiles...

38eb0a7a82 softgpu: Check for queued compile. 
Rarely, we could have queued compiling the same one, which would crash on
a double insert.

4d06400548 softgpu: Fix compile hazard while running. 
This prevents any clearing of cache while other threads may be using
previously cached funcs, and avoids wx exclusive hazards.

ce51942508 softgpu: Correct WX-exclusive platform hazards. 
Should mainly affect BSD at this point.

c47d7eab38 softgpu: Simply 5551 blending fast path. 
Since it only supports multiply and add, let's just stick with that.

6e6535c263 softjit: Skip reading dst pixel where blended out. 
Sometimes used by blends used purely to multiply the source color by
something, usually prep for bloom.

e72309745e softjit: Implement accurate fog color blending. 2022-09-11 08:50:07 -07:00
Unknown W. Brackets
b90fc7137f softgpu: Correct accuracy of fog calculation. 
This matches values from a PSP exactly, with the help of immediate mode
vertex values (since this directly allows specifying the fog factor
without any floating point math.)

15d5fa48f7 softgpu: Check depth test early on simple stencil. 
If we don't need to write stencil on sfail/zfail, we can do the depthtest
early, which allows us to more often skip texture sampling.

This gives a good improvement in Chains of Olympus.

2479d52202 Global: Reduce includes of common headers. 
In many places, string, map, or Common.h were included but not needed.

6c723c0517 softjit: Fix src blend factor handling. 
This was causing us to skip a shift, oops.

c2985bca31 softjit: Centralize some common funcs from sampler. 
No need to duplicate this code.

ac2b96cec0 softjit: Switch to constant pool. 
This is simpler without RIP access checks, and tends to be fast.

fc292b127b softgpu: Correct dither matrix lookup. 
Oops, need to wrap x/y, of course...

355bad666c softjit: Optimize common case bloom blending. 
Bloom often uses fixed ONE + ONE, which is a lot less work for us.  And
bloom often runs over and over again on pixels, so saving work is good.

2d8fdd8cf4 Math3D: Allow construction from NEON vectors. 
This makes it match SSE and easier to keep things generic.  Will impact
alignment of non-packed Vec2/Vec3.
