# SPIR-V Headers

+This repository contains machine-readable files for the
[SPIR-V Registry](https://www.khronos.org/registry/spir-v/).

+* JSON files describing the grammar for the SPIR-V core instruction set
+ and the extended instruction sets.
* The XML registry file.
+* A tool to build the headers from the JSON grammar.
-Under the [include](include) directory, header files are provided according to
-their own version. Only major and minor version numbers count.
-For example, the headers for SPIR-V 1.1 are in
-[include/spirv/1.1](include/spirv/1.1). Also, the headers for the 1.0 versions
-of the GLSL.std.450 and OpenCL extended instruction sets are in
-[include/spirv/1.0](include/spirv/1.0).
+Headers are provided in the [include](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.

-A newer revision of a header file always replaces an older revision of

-`include/spirv/1.0/spirv.h` and if there is a Rev 5, then it will be placed
-in the same location.
-The SPIR-V XML registry file is updated by the Khronos registrar whenever

+The SPIR-V XML registry file is updated by Khronos whenever a new enum range is allocated.
-In particular, pull requests that update header files will not be accepted.

2. Use `${SPIRV-Headers_SOURCE_DIR}/include}` in a `target_include_directories`
directive.
3. In your C or C++ source code use `#include` directives that explicitly mention
- the `spirv` path component. For example the following uses SPIR-V 1.1
- core instructions, and the 1.0 versions of the GLSL.std.450 and OpenCL
- extended instructions.
+ the `spirv` path component.
```
-#include "spirv/1.0/GLSL.std.450.h"

-#include "spirv/1.1/spirv.hpp"
+#include "spirv/unified1/GLSL.std.450.h"
+#include "spirv/unified1/OpenCL.std.h"
+#include "spirv/unified1/spirv.hpp"
```
See also the [example](example/) subdirectory. But since that example is
*inside* this repostory, it doesn't use and `add_subdirectory` directive.
+## Generating the headers from the JSON grammar
+
+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 `buildHeaders` directory.
+Use CMake to build the project, in a `buildHeaders/build` subdirectory.
+There is a bash script at `buildHeaders/bin/makeHeaders` that shows how to use the built
+header-generator binary to generate the headers from the JSON grammar.
+
+Notes:
+- this generator is used in a broader context within Khronos to generate the specification,
+ and that influences the languages used, for legacy reasons
+- the C++ structures built may similarly include more than strictly necessary, for the same reason
+
## FAQ
* *How are different versions published?*
- All versions are present in the master branch of the repository.
- They are located in different subdirectories under
- [include/spirv](include/spirv), where the subdirectory at that
- level encodes the major and minor version number of the relevant spec.
-
- An application should consciously select the targeted spec version
- number, by naming the specific version in its `#include` directives,
- as above and in the examples.
+ 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?*
