SPIR-V is a binary intermediate language for representing graphical-shader stages and compute kernels for multiple Khronos APIs, including OpenCL, OpenGL, and Vulkan.
- A registry of SPIR-V extensions
- Issue tracking for all SPIR-V specifications
- Pull requests to add new SPIR-V extensions
To publish a new extension, please create a pull request which includes:
- The extension document in the asciidoc format named following
the
SPV_<vendor>_<name>.asciidocpattern. The document should be placed in theextension/<vendor>folder. - README.md update with the link to the new extension once published
To publish a non-semantic extended instruction set,
- The instruction set in the asciidoc format named following
the
NonSemantic.<name>.asciidocpattern. The document should be placed in thenonsemanticfolder. - README.md update with the link to the new extension once published
Please see BUILD.md for instructions to create an HTML specification for this repo.
Note: we no longer push the HTML along side the extension.
