clang-tidy and CUDA

Hello,

is it somehow possible to specify source file extension for clang-tidy, can it for example parse ".cu" files? Is there some support for CUDA in clang-tidy? I ran it on my CUDA source file (which I have to rename to ".cc" file), specified -D__CUDACC__, and it found error: unknown type name '__host__' [clang-diagnostic-error].

Any help would be appreciated.
