[Bug middle-end/32152] New: omp lowering creates mismatched types

[rguenth at gcc dot gnu dot org]

For gcc.dg/gomp/atomic-6.c we create (x86_64)

  D.2052 = (unsigned int) D.2043;
  D.2056 = (unsigned int) D.2044;
  D.2057 = (unsigned int) D.2043;
  D.2058 = __sync_val_compare_and_swap_4 (D.2051, D.2057, D.2056);
  D.2043 = (int) D.2058;
  if (D.2043 != D.2052)

which compares a signed integer against an unsigned one.
