SPVGEN

SPVGEN is a libaray to generate SPIR-V binary. It integrates glslang and SPIRV-Tools.

APIs

The APIs are listed in spvgen.h and vfx.h.

Initialization

• InitSpvGen()

Convert GLSL to SPIR-V binary

• spvCompileAndLinkProgram()
• spvGetSpirvBinaryFromProgram()
• spvDestroyProgram()

Assemble SPIR-V

• spvAssembleSpirv()

Disassemble SPIR-V

• spvDisassembleSpirv()

Optimize SPIR-V

• spvOptimizeSpirv
• spvFreeBuffer

Validate SPIR-V

• spvValidateSpirv()

Parse .pipe file

• vfxParseFile()
• vfxGetPipelineDoc()
• vfxCloseDoc()

How to build

cd external/
python fetch_external_sources.py
cd ..
cmake -H. -Brbuild64 -DCMAKE_BUILD_TYPE=release -DXGL_LLPC_PATH=<PATH_TO_LLPC> 
cd rbuild64
make
cd ..
cmake -H. -Bdbuild64 -DCMAKE_BUILD_TYPE=Debug -DXGL_LLPC_PATH=<PATH_TO_LLPC>
cd dbuild64
make

To build 32bit library, please add "-DCMAKE_C_FLAGS=-m32 -DCMAKE_CXX_FLAGS=-m32" in cmake.

SPVGEN depends on LLPC header files. You need to download the files from llpc/include/.
