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.
