Lower varying parameters as pointers instead of SSA values. (#5919)

2025-01-08T06:26:31+00:00

* Add executable test on matrix-typed vertex input. * Fix emit logic of matrix layout qualifier. * Pass fragment shader varying input by constref to allow EvaluateAttributeAtCentroid etc. to be implemented correctly.

Fix bug in `translateGlslGlobalVar()`. (#5181)

fix `WorkgroupSize()` compiler failiure (#4505)

in some cases was not destroying the hoisted to global `WorkgroupSize()` function removed capability requirement on `gl_WorkGroupSize` since no longer appies (kIROp of `WorkgroupSize` is implemented for all targets) change when destroying inst

Support derivative functions in compute & capabilities adjustments (#4014)

2024-04-25T13:18:32+00:00

* Support derivative functions in compute & capabilities adjustments fixes #4000 PR implements derivative functions in compute shaders properly so we have the functionality for SPIR-V & GLSL. Tests reflect fragment and compute paths. PR also adjusts capabilities to correct wrong SPRI-V target capabilities for when using textures. Remarks: 1. __requireComputeDerivative(); is a intrinsic_op and not modifier since inlining will destroy the modifier. 2. Derivative mode is tied to an entry point decoration `[DerivativeGroupQuad]`/`[DerivativeGroupLinear]` or GLSL syntax ``derivative_group_linearNV`. Default is to set the mode to `[DerivativeGroupQuad]` * remove -emit-spirv-directly * fixes 1. fix minor issue fwidth change where I returned the wrong type 2. fix issue where glslang{glsl->spirv} is wrong, so we don't run that test and just run the glsl test & direct spir-v test for intrinsic-texture.slang * adjust as per review and refine code 1. add test to ensure multi-diverging-in-logic entry points work -- 2 functions which may cause computeDerivatives + 1 that uses, 1 that does not. 2. naming 3. use entry point ref graph for c-like-targets 4. reordered some code to util's and removed `static linline` since that was just for ease of coding on my end (should not have been pushed). * Grammer * split up source file + issolate GLSL emit path change. --------- Co-authored-by: Yong He
