[Bug fortran/25219] New: [GOMP] ICE with SAVE attribute and (FIRST|LAST)PRIVATE

[rofi at ya dot com]

When -fopenmp is enabled, SAVE attribute causes an ICE when the entity is
referenced in a FIRSTPRIVATE or LASTPRIVATE clause, e.g.:

PROGRAM p
  IMPLICIT NONE
  ! This can be SAVE :: K and gfortran will ICE too
  SAVE 

  INTEGER :: K, I

  K = 3

  ! These two can be replaced with 
  ! !$OMP PARALLEL DO LASTPRIVATE(K) and will ICE too
  !$OMP PARALLEL
    !$OMP DO LASTPRIVATE(K)
    DO I = 1, 100
     K = I
    END DO
    !$OMP END DO
  !$OMP END PARALLEL

  PRINT *, K
END PROGRAM p

Sorry, I got wrong when working with my test files.

With !$OMP PARALLEL DO LASTPRIVATE(K) it does not ICE.

[Bug fortran/25219] [GOMP] ICE with SAVE attribute and (FIRST|LAST)PRIVATE

This is not Fortran specific,
int main (void)
{
  static int i;
  static int k;

  k = 3;
  #pragma omp parallel
    #pragma omp for private(i) lastprivate(k)
      for (i = 1; i <= 100; i = i + 1)
        k = i;

  __builtin_printf ("%d\n", k);
  return 0;
}

ICEs the same.  I can't reproduce this in the Fedora Core gcc though,
so I think this got fixed by
http://gcc.gnu.org/ml/gcc-patches/2005-12/msg01192.html
Dunno about its status, Diego, was it subsummed by your
http://gcc.gnu.org/ml/gcc-patches/2006-01/msg00668.html
patch?

No, it's unrelated.  I've committed Aldy's patch.
