Fixes a bunch of freezes with SPIR-V on AMD hardware, and validation errors. Note: Obviously assumes input offsets are constant, which they currently are.
- Pools for Instructions and LiteralIntegers. Can be passed in when creating the generator module.
- NewInstruction is called instead of new Instruction()
- Ryujinx SpirvGenerator passes in some pools that are static. The idea is for these to be shared between threads eventually.
- Estimate code size when creating the output MemoryStream
- LiteralInteger pools using ThreadStatic pools that are initialized before and after creation... not sure of a better way since the way these are created is via implicit cast.
Also, cache delegates for Spv.Generator for functions that are passed around to GenerateBinary etc, since passing the function raw creates a delegate on each call.
TODO: update python spv cs generator to make the coregrammar with NewInstruction and the `params` overloads.
* Stop using glTransformFeedbackVarying and use explicit layout on the shader
* This is no longer needed
* Shader cache version bump
* Fix gl_PerVertex output for tessellation control shaders
* Add support for render scale to vertex stage.
Occasionally games read off textureSize on the vertex stage to inform the fragment shader what size a texture is without querying in there. Scales were not present in the vertex shader to correct the sizes, so games were providing the raw upscaled texture size to the fragment shader, which was incorrect.
One downside is that the fragment and vertex support buffer description must be identical, so the full size scales array must be defined when used. I don't think this will have an impact though. Another is that the fragment texture count must be updated when vertex shader textures are used. I'd like to correct this so that the update is folded into the update for the scales.
Also cleans up a bunch of things, like it making no sense to call CommitRenderScale for each stage.
Fixes render scale causing a weird offset bloom in Super Mario Party and Clubhouse Games. Clubhouse Games still has a pixelated look in a number of its games due to something else it does in the shader.
* Split out support buffer update, lazy updates.
* Commit support buffer before compute dispatch
* Remove unnecessary qualifier.
* Address Feedback
* Support coherent images
* Add support for fragment shader interlock
* Change to tree based match approach
* Refactor + check for branch targets and external registers
* Make detection more robust
* Use Intel fragment shader ordering if interlock is not available, use nothing if both are not available
* Remove unused field
* Another workaround for NVIDIA driver 496.13 shader bug
This might work better than the other one. Give this a test to see if it fixes/doesn't fix issues with the other one.
The problem seems to be when any variable assignment happens with a negation. `temp_1 = -temp_0;` seems to trigger weird behaviour, but `temp_1 = 0.0 - temp_0;` does not. This also might to extend towards integer types?
* Update cache version
* Add disclaimer comment
* Wording
* Initial Implementation
* Further improvements (no support for float/64-bit types)
* Merge atomic and reduce instructions, add missing format switch
* Fix rebase issues.
* Not used.
* Whoops. Fixed.
* Partial implementation of inc/dec, cleanup and TODOs
* Remove testing path
* Address Feedback
* Replace BGRA and scale uniforms with a uniform block
* Setting the data again on program change is no longer needed
* Optimize and resolve some warnings
* Avoid redundant support buffer updates
* Some optimizations to BindBuffers (now inlined)
* Unify render scale arrays
