[Bug middle-end/27388] New: omp_is_private issues

[jakub at gcc dot gnu dot org]

void
foo (void)
{
  int i;
  i = 0;
#pragma omp parallel shared (i)
    {
#pragma omp master
      i++;
#pragma omp parallel for
      for (i = 0; i < 10; i++)
        ;
    }
}

results in very weird omplower dump:
1) #pragma omp parallel shared(iD.1922) private(iD.1922)
   for the outer parallel
   (surely we don't want i being shared and private at the same time,
   just shared here)
2) #pragma omp parallel shared(iD.1922)
   for the inner parallel - in this case i certainly ought to be private,
   not shared
I think 1) is caused by n->value = GOVD_PRIVATE; messing up outer context,
while 2) probably because omp_is_private shouldn't recurse over is_parallel
contexts.
