--- Comment #4 from Thomas Schwinge <tschwinge at gcc dot gnu.org> ---
For C, we get:


    [...]/c-c++-common/goacc/clause-locations.c:12:53: warning: conflicting
reduction operations for 'sum'
       12 |         #pragma acc loop reduction(-:diff) reduction(-:sum)
          |                                                     ^

For C++, we get:

    [...]/c-c++-common/goacc/clause-locations.c:12:56: warning: conflicting
reduction operations for 'sum'
       12 |         #pragma acc loop reduction(-:diff) reduction(-:sum)
          |                                                        ^~~

For Fortran, we get:

    [...]/gfortran.dg/goacc/clause-locations.f90:11:47:

       11 |       !$acc loop reduction(-:diff) reduction(-:sum)
          |                                               ^
    Warning: conflicting reduction operations for 'sum'

These are all three slightly different.  None of them actually points to the
"reduction operation".  Certainly not a priority to fix or at least unify this,
but still noting this here, in case anyone ever feels like improving that.
