2024-04-25Support derivative functions in compute & capabilities adjustments (#4014)ArielG-NV
* 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 <yonghe@outlook.com>

2024-04-03Implement 8.14-8.19 of OpenGL-GLSL specificationArielG-NV
The following PR implements 8.14-8.19 of the [OpenGL-GLSL specification](https://registry.khronos.org/OpenGL/specs/gl/GLSLangSpec.4.60.pdf). Fully implements all functions and built-in type's, resolves https://github.com/shader-slang/slang/issues/3692 for GLSL & SPRI-V targets. _Notes:_ Testing Tools: * Fragment shaders cannot test computational results. Only OpCodes are checked for proper emitting. Implementation Notes: * SubpassInput requires an unknown image format. * SubpassInput is disjoint from TextureType: __SubpassImpl (.slang) & SubpassInputType (Compiler) to reduce code generation required. * SubpassInput required an additional input layout modifier, input_attachment_index, this was added as a new parameter binding attribute. Since the following qualifiers can overlap with different resources (`layout(input_attachment_index = 0, binding = 0, set = 0)`) input_attachment_index is checked for overlapping resource bindings separately from other qualifiers with `LayoutResourceKind::InputAttachmentIndex`. * `GLSLInputAttachmentIndexLayoutModifier` was added to enforce function parameters only accepting `in` decorated variables. * `in` decorated variables needed to have emitting modified to allow directly emitting the variable into function calls if used as a parameter, normally Slang has a "global variable" shadow as a "global parameter" through a copy. This does not work and is solved using `GlobalVariableShadowingGlobalParameterDecoration` to build a relationship of "global variable" to "global parameter", we then resolve this relationship and replace "global variable" uses later in compile. * `AtomicCounterMemory` memory-constraint requires `OpCapability AtomicStorage`, `AtomicStorage` is invalid for Vulkan targets. glslang outputs for `barrier`, `memoryBarrier`, and `groupMemoryBarrier` `AtomicCounterMemory` as a memory constraint. This compiles as valid SPIR-V for Vulkan since `OpCapability AtomicStorage` is not declared. This behavior of glslang is undefined as per [3.31.Capability of the SPIR-V specification](https://registry.khronos.org/SPIR-V/specs/unified1/SPIRV.html#_capability). We will omit `AtomicCounterMemory` from our barrier calls.
