In HLSL, there are three (TODO: ??) dimensions of clip and cull distance values: * The semantic's value N, ala SV_ClipDistanceN. * The array demension, if the value is an array. * The vector element, if the value is a vector or array of vectors. In SPIR-V, clip and cull distance are arrays of scalar floats, always. This PR currently ignores the semantic N axis, and handles the other two axes by sequentially copying each vector element of each array member into sequential floats in the output array. Fixes: #946
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.
