Glslang
Khronos-reference front end for GLSL/ESSL, partial front end for HLSL
...Those binaries are automatically uploaded by the build bots after successful testing and they always reflect the current top of the tree of the master branch. Right now, there are two test harnesses existing in glslang: one is Google Test, one is the runtests script. The former runs unit tests and single-shader single-threaded integration tests, while the latter runs multiple-shader linking tests and multi-threaded tests. Test results should always be included with a pull request that modifies functionality.
