This PR adds a CreateParseContext() fn analogous to CreateBuiltInParseables(), to create a language specific built in parser. (This code was present before but not encapsualted in a fn). This can now be used to create a source language specific parser for builtins. Along with this, the code creating HLSL intrinsic prototypes can now produce them in HLSL syntax, rather than GLSL syntax. This relaxes certain prior restrictions at the parser level. Lower layers (e.g, SPIR-V) may still have such restrictions, such as around Nx1 matrices: this code does not impact that. This PR also fleshes out matrix types for bools and ints, both of which were partially in place before. This was easier than maintaining the restrictions in the HLSL prototype generator to avoid creating protoypes with those types. Many tests change because the result type from intrinsics moves from "global" to "temp". Several new tests are added for the new types.
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.
