[cfe-dev] Cuda Refactoing

[Jacques Pienaar via cfe-dev]

Hey Bahram,

For the first part (recognize CUDA tokens), look in the clang/test/SemaCUDA
directory for how clang is invoked to parse CUDA tokens
(clang/test/SemaCUDA/function-target-hd.cu shows invocation variants).
There is also some support already to query the AST for CUDA nodes. For
example, a kernel launch (<<<,>>>) is matched by the AST
matcher cudaKernelCallExpr.

Can you expand more on the bitcode part? I'm not quite following the flow
of what your tool does, i.e., what does it take as input and what do you
wish to generate with it?

Best,

Jacques
