Hi,
these flags all tell Cycles which kind of shaders are used (Do we have a
Surface (or only volume), Emission or a Transparent BSDF)?
They are set and checked for in various places in render/ e.g.
shader.cpp, light.cpp ...
Again, please just search the code yourself. You should really be able
to search a codebase for a variable. That is not magic.
