This repository contains machine-readable files for the SPIR-V Registry. This includes:
Headers are provided in the include directory, with up-to-date headers in the
unified1 subdirectory. Older headers are provided according to their version.
In contrast, the XML registry file has a linear history, so it is not tied to SPIR-V specification versions.
When a new version or revision of the SPIR-V specification is published, the SPIR-V Working Group will push new commits onto master, updating the files under include.
The SPIR-V XML registry file is updated by Khronos whenever a new enum range is allocated.

Care should be taken to follow existing precedent in populating the details of reserved tokens. This includes:
"version" : "None"
mkdir build cd build cmake .. cmake --build . --target install
Then, for example, you will have
If you want to install them somewhere else, then use

A CMake-based project can use the headers without installing, as follows:
add_subdirectorydirective to include this source tree.
#includedirectives that explicitly mention the
#include "spirv/unified1/GLSL.std.450.h" #include "spirv/unified1/OpenCL.std.h" #include "spirv/unified1/spirv.hpp"
See also the example subdirectory. But since that example is inside this repostory, it doesn't use and
This will generally be done by Khronos, for a change to the JSON grammar. However, the project for the tool to do this is included in this repository, and can be used to test a PR, or even to include the results in the PR. This is not required though.
The header-generation project is under the
tools/buildHeaders directory. Use CMake to build the project, in a
build subdirectory (under
tools/buildHeaders). There is then a bash script at
bin/makeHeaders that shows how to use the built header-generator binary to generate the headers from the JSON grammar. (Execute
bin/makeHeaders from the
How are different versions published?
The multiple versions of the headers have been simplified into a single
unified1 view. The JSON grammar has a “version” field saying what version things first showed up in.
How do you handle the evolution of extended instruction sets?
Extended instruction sets evolve asynchronously from the core spec. Right now there is only a single version of both the GLSL and OpenCL headers. So we don't yet have a problematic example to resolve.
