# HLSLcc DirectX shader bytecode cross compiler. Originally based on https://github.com/James-Jones/HLSLCrossCompiler. This library takes DirectX bytecode as input, and translates it into the following languages: - GLSL (OpenGL 3.2 and later) - GLSL ES (OpenGL ES 2.0 and later) - GLSL for Vulkan consumption (as input for Glslang to generate SPIR-V) - Metal Shading Language This library is used to generate all shaders in Unity for OpenGL, OpenGL ES 3.0+, Metal and Vulkan. Changes from original HLSLCrossCompiler: - Codebase changed to C++11, with major code reorganizations. - Support for multiple language output backends (currently ToGLSL and ToMetal) - Metal language output support - Temp register type analysis: In DX bytecode the registers are typeless 32-bit 4-vectors. We do code analysis to infer the actual data types (to prevent the need for tons of bitcasts). - Loop transformation: Detect constructs that look like for-loops and transform them back to their original form - Support for partial precision variables in HLSL (min16float etc). Do extra analysis pass to infer the intended precision of samplers. - Reflection interface to retrieve the shader inputs and their types. - Lots of workarounds for various driver/shader compiler bugs. - Lots of minor fixes and improvements for correctness - Lots of Unity-specific tweaks to allow extending HLSL without having to change the D3D compiler itself. ## Note This project is originally integrated into the Unity build systems. However, building this library should be fairly straightforward: just compile `src/*.cpp` (in C++11 mode!) and `src/cbstring/*.c` with the following include paths: - include - src/internal_includes - src/cbstrinc - src Alternatively, a CMakeLists.txt is provided to build the project using cmake. The main entry point is TranslateHLSLFromMem() function in HLSLcc.cpp (taking DX bytecode as input). ## Contributors - Mikko Strandborg - Juho Oravainen - David Rogers - Marton Ekler - Antti Tapaninen - Florian Penzkofer - Alexey Orlov - Povilas Kanapickas - Aleksandr Kirillov - Kay Chang ## License MIT license for HLSLcc itself, BSD license for the bstring library.
