Making it easier to work with shaders https://git.yummers.dev/slang.git/atom?h=master 2024-08-26T19:11:41+00:00 2024-08-26T19:11:41+00:00 ArielG-NV 159081215+ArielG-NV@users.noreply.github.com 2024-08-26T19:11:41+00:00 urn:sha1:e1c6fecd90142761aaecbf4e281beb87893fc531 * Implement `-fvk-use-dx-layout` Fixes: #4126 Changes: * Added fvk-use-dx-layout * Modified `HLSLConstantBufferLayoutRulesImpl` for correctness (ex: Array is always 16 byte aligned) * Added kFXCShaderResourceLayoutRulesFamilyImpl and kFXCConstantBufferLayoutRulesFamilyImpl to handle fvk-use-dx-layout * Added `ConstantBufferLayoutRules` to manage constant buffer rules * Added `alignCompositeElementOfNonAggregate`/`alignCompositeElementOfAggregate` to handle forced alignment of composites for ConstantBuffers * `StructuredBuffer` rules are mostly equal to `scalar` layout, not much was needed to be changed to support this behavior. * seperate legacy constant buffer and how Slang does constant-buffer normally * undo an addition * remove accidental test * Address review and fix Address review and remove GLSL support since GLSL requires a seperate legalization (need to linearlize structs like with `legalizeMetalIR` to assign explicit offsets) * comments * remove aggregate and non-aggregate logic We don't need this distinction for the logic --------- Co-authored-by: Yong He <yonghe@outlook.com>
