Before this change, using gl_MeshPrimitivesEXT in mesh shader would unconditionally create gl_MeshPrimitivesEXT.gl_PrimitiveShadingRateEXT field and add PrimitiveShadingRateKHR capability to the output SPIRV file, which would subsequently trigger validation errors when creating the shader module unless the application requested primitive shading rate feature. What should happen instead is that unless GL_EXT_fragment_shading_rate extension is enabled, we should not allow using gl_PrimitiveShadingRateEXT and should not emit the associated fields into the output. This change fixes this by using existing filterMember mechanism that is already used in a few other cases like this, and adjusting the required extension on the field member which will generate an error when gl_PrimitiveShadingRateEXT is used without enabling the extension.
Glslang Tests based on the Google Test Framework
This directory contains Google Test based test fixture and test cases for glslang.
Apart from typical unit tests, necessary utility methods are added into
the GlslangTests fixture to provide the ability to do
file-based integration tests. Various *.FromFile.cpp files lists names
of files containing input shader code in the Test/ directory. Utility
methods will load the input shader source, compile them, and compare with
the corresponding expected output in the Test/baseResults/ directory.
How to run the tests
Please make sure you have a copy of Google Test checked out under
the External directory before building. After building, just run the
ctest command or the gtests/glslangtests binary in your build directory.
The gtests/glslangtests binary also provides an --update-mode command
line option, which, if supplied, will overwrite the golden files under
the Test/baseResults/ directory with real output from that invocation.
This serves as an easy way to update golden files.
