OpenMP with Clang

[my-HenryS]

Hi lalanne,

I happened to find your repo when searching for the usage of 'isa<OMPExecutableDirective>' on github.

I am trying to build a clang tool and one of the tasks is to find all #pragma in a program that relates to OpenMP. A striaghtforward way is to traverse the AST and check if the Stmt is a 'OMPExecutableDirective'. However, it seems that the tool does not work as expected and it might be that my Clang/LLVM 3.5.0 does not support OpenMP.

I also tried clang-omp and built a library 'libiomp5.so' from that. It still does not work.

Would you mind sharing your environment (Clang/LLVM) you used for this 'StoSClangExperiment' repo? And what are the steps to make your code work for OpenMP?

Thanks,
Jinghan
