This checkin adds a --flatten-uniform-arrays option which can break uniform arrays of samplers, textures, or UBOs up into individual scalars named (e.g) myarray[0], myarray[1], etc. These appear as individual linkage objects. Code notes: - shouldFlatten internally calls shouldFlattenIO, and shouldFlattenUniform, but is the only flattening query directly called. - flattenVariable will handle structs or arrays (but not yet arrayed structs; this is tested an an error is generated). - There's some error checking around unhandled situations. E.g, flattening uniform arrays with initializer lists is not implemented. - This piggybacks on as much of the existing mechanism for struct flattening as it can. E.g, it uses the same flattenMap, and the same flattenAccess() method. - handleAssign() has been generalized to cope with either structs or arrays. - Extended test infrastructure to test flattening ability.
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.
