[cfe-dev] OpenMP pragmas transformation to library calls

[Babis Chalios]

Hello,

Is there any way to find out how does clang transform the OpenMP pragmas 
to the
corresponding library calls?

I m interested, for example, to find out how this code example:
*
void task_func(int a, int b)
{
     ...
}

int main()
{
     int i;

     #pragma omp parallel
{
     #pragma omp single
     for (i=0; i<10; ++i) {
         #pragma omp task
         task_func(i, i+1);
     }
     #pragma omp taskwait
}
     return 0;
}*


could be written, using direct calls to the LLVM OpenMP library. Does 
clang provide
a way to see the equivalent code with calls to the library?

I looked around a bit to find out if there is such way, or the 
equivalent information
on how I would use the library and handcode an application to use direct 
calls to it,
but I couldn't find something.

If anyone knows how I could achieve this or point to somewhere I could 
read something
relevant it would be very nice.

Cheers,
Babis
