            Bug ID: 118496
           Summary: [OpenMP] "omp unroll" parsed — but not active
           Product: gcc
           Version: 15.0
            Status: UNCONFIRMED
          Keywords: openmp
          Severity: normal
          Priority: P3
         Component: middle-end
          Assignee: unassigned at gcc dot gnu.org
          Reporter: burnus at gcc dot gnu.org
                CC: jakub at gcc dot gnu.org
  Target Milestone: ---

Trying the following with GCC 15 still keeps the loop:

void f() {
      #pragma omp unroll partial(5)
        for (int i =0 ; i < 5; i++)
          __builtin_printf("Hello world\n");
}

void g() {
      #pragma omp unroll full
        for (int i =0 ; i < 5; i++)
          __builtin_printf("Hello world\n");
}

The original patch handles unrolling, when trying OG13 (devel/omp/gcc-13) it
properly unrolls.
