From e1c6fecd90142761aaecbf4e281beb87893fc531 Mon Sep 17 00:00:00 2001 From: ArielG-NV <159081215+ArielG-NV@users.noreply.github.com> Date: Mon, 26 Aug 2024 15:11:41 -0400 Subject: Implement `-fvk-use-dx-layout` (#4912) * 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 --- source/slang/slang-compiler-options.cpp | 1 + 1 file changed, 1 insertion(+) (limited to 'source/slang/slang-compiler-options.cpp') diff --git a/source/slang/slang-compiler-options.cpp b/source/slang/slang-compiler-options.cpp index ea2593713..3325a313a 100644 --- a/source/slang/slang-compiler-options.cpp +++ b/source/slang/slang-compiler-options.cpp @@ -110,6 +110,7 @@ namespace Slang break; case CompilerOptionName::EmitSpirvDirectly: case CompilerOptionName::GLSLForceScalarLayout: + case CompilerOptionName::ForceDXLayout: case CompilerOptionName::MatrixLayoutRow: case CompilerOptionName::MatrixLayoutColumn: case CompilerOptionName::VulkanInvertY: -- cgit v1.2.3
