Support for CUDA header file (.hcu, .cuh)

[DiTurr]

Hi,

it would be good to add support for CUDA header files (.hcu, .cuh). It should not be a big change I think because it uses the commenting method 'C/C++ Header'

• language name: CUDA header files
• file extension(s): .hcu, .cuh
• method(s) of commenting text: 'C/C++ Header'

No processing of cu extension?

Correction .cuh is supported but not .hcu.

I think .hcu is also an accepted extension for CUDA header files.

cloc already supports CUDA:

./cloc-1.94.pl --explain CUDA
CUDA
    filter rm_comments_in_strings  "  /*  */
    filter rm_comments_in_strings  "  //  
    filter call_regexp_common  C++
    extensions: cu, cuh

Is it worthwhile to separate the header files to their own category, CUDA Header?
