[cfe-dev] [llvm-dev] omp critical supported in llvm?

[Hahnfeld, Jonas via cfe-dev]

Hi,

 

Sorry for not seeing this, but Chandler is right that this should go to cfe-dev or even openmp-dev if it’s related to the runtime (which I think this one is not).

 

To your question: Yes, clang 3.8 and later has support for ‘#pragma omp critical’ if you specify –fopenmp (clang 3.7 needed –fopenmp=libomp).

If this does not work, could you share the code and the exact command used to compile?

 

Regards,

Jonas

Hi everyone,

Does llvm propoerly support "omp critical" directive? I'm asking because I have been using this directive in my code but I still observe some data races. To check if I am correct, I compiled the code with gcc and used Intel inspector for data races and nothing is reported. That is why I am asking here if LLVM properly implements the specifications for openmp, specially critical directive.

Best,

Mohammad
