            Bug ID: 103938
           Summary: ICE with __builtin_prefetch and vectors
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Keywords: ice-checking, ice-on-valid-code
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pinskia at gcc dot gnu.org
  Target Milestone: ---

Take:
typedef unsigned long u64x2 __attribute__ ((vector_size(16)));
void g (u64x2 off)
{
  __builtin_prefetch ((void*)off[0], 0, 3);
}

This ICEs at -O2 and above.
