SPVGEN

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

APIs

The APIs are listed in include/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

SPVGEN is now built as part of the AMDVLK build system, but is not built by default.

First, follow the AMDVLK instructions to get sources and use cmake to set up the build.

Then, use

cd spvgen/external && python fetch_external_sources.py
cd xgl && cmake --build {build directory} --target spvgen
