           Version: 5.0
            Status: UNCONFIRMED
          Keywords: openmp, rejects-valid

One of the recent GCC changes causes -fopenmp-simd to reject code, which
compiled before (by ignoring it):


gcc -fno-openmp -fopenmp-simd foo.c
foo.c: In function ‘main’:
foo.c:4:17: error: expected end of line before ‘collapse’
 #pragma omp for collapse(1)
                 ^


void foo() { }

int main() {
#pragma omp for collapse(1)
  for (int i = 1; i <= 151; i+=31)
     foo();
}
