DirectXShaderCompiler
DirectXShaderCompiler is an HLSL shader compiler that transforms High-Level Shader Language source code into intermediate language formats executable by GPUs. It functions as a shader bytecode validator to verify the correctness and hardware compatibility of compiled representations and as a software shader rasterizer for rendering when physical graphics hardware is unavailable.
The project includes a translation tool that converts HLSL shader code into the SPIR-V binary intermediate representation for use with cross-platform graphics APIs. It also provides capabilities for legacy shader migration by translating older shader bytecode formats into modern versions.
The toolset covers a broad range of capabilities, including cross-platform shader development and Vulkan SPIR-V integration.
Features
- Shader Cross-Compilation Pipelines - Transforms High-Level Shader Language source code into intermediate formats for execution by graphics drivers.
- Cross-Platform Shader Compilers - Transforms unified shader code into platform-specific binaries to ensure visual consistency across different hardware.
- Multi-API Shader Compilations - Generates GPU kernel code for multiple graphics APIs from a single HLSL shader source.
- SPIR-V Translation Tools - Translates HLSL shader constructs directly into the cross-platform SPIR-V binary format.
- SPIR-V Translators - Translates HLSL shader code into SPIR-V binary intermediate representation for use with cross-platform graphics APIs.
- Software Rasterizers - Provides a software-based rasterizer to render shaders when physical graphics hardware is unavailable or unsupported.
- Bytecode Migration - Translates older shader bytecode formats into modern versions for compatibility with new graphics drivers.
- Common Intermediate Languages - Generates platform-independent instruction sets as a portable representation before native GPU compilation.
- Intermediate Representations - Employs multiple internal data structures to decouple language parsing from final hardware target generation.
- LLVM-Based Compilers - Utilizes the LLVM toolchain as a backend to generate optimized machine-level intermediate bytecode.
- Shader Bytecode Versioning - Translates older shader bytecode formats into modern versions to maintain compatibility with current drivers.
- Static Bytecode Validations - Performs static analysis on compiled binary shaders to ensure they meet hardware specification requirements.
- Shader Validation - Verifies that compiled shader intermediate representations are correct and compatible with the target hardware.
- Graphics API Guides - Compiler infrastructure for DirectX shader development.
