            Bug ID: 64765
           Summary: [OpenACC] Bogus "'copy' is not valid for '#pragma acc
                    kernels loop'"
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Keywords: openacc, rejects-valid
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: burnus at gcc dot gnu.org
                CC: tschwinge at gcc dot gnu.org

The following program gives

foo.c:2:36: error: 'copy' is not valid for '#pragma acc kernels loop'
foo.c:2:26: error: 'create' is not valid for '#pragma acc kernels loop'
 #pragma acc kernels loop create(f) copy(r)
                          ^

I believe copy and create are invalid for LOOP but they should be valid for
KERNELS - and, hence, also for KERNEL LOOPS. (The equivalent Fortran program
compiles.)


Test case:

void foo(float *f, double *r) {
#pragma acc kernels loop create(f) copy(r)
for(;;) {}
}
