            Bug ID: 90763
           Summary: vec_xl_len should take constnan
           Product: gcc
           Version: 8.3.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: slandden at gmail dot com
  Target Milestone: ---

This should compile (that const is preventing it):

#include <altivec.h>
vector char vec_load_const(const unsigned char *s, int num) {
    return vec_xl_len(s, num);
}
