            Bug ID: 67504
           Summary: ICE with type dependent collapse argument
           Product: gcc
           Version: 5.2.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jakub at gcc dot gnu.org
  Target Milestone: ---

int bar (int);
double bar (double);

template <typename T>
void
foo (T x)
{
  #pragma omp for collapse (bar (x)) // { dg-error "collapse argument needs
positive constant integer expression" }
  for (int i = 0; i < 10; i++)
    ;
}

ICEs during the testing, we should check for tree_fits_shwi_p first before
testing INTEGRAL_TYPE_P.
