This fixes: 1. A compilation error when assigning scalars to matricies 2. A semantic error in matrix construction from scalars. This was initializing the diagonal, where HLSL semantics require the scalar be replicated to every matrix element. 3. Functions accepting mats can be called with scalars, which will be shape-converted to the matrix type. This was previously failing to match the function signature. NOTE: this does not yet handle complex scalars (a function call, say) used to construct matricies. That'll be added when the node replicator service is available. For now, there's an assert. There's one new test (hlsl.scalar2matrix.frag). An existing test lsl.type.half.frag changes, because of (2) above, and a negative test error message changes due to (3) above. Fixes #923.
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.
