            Bug ID: 90323
           Summary: ppc should convert equivalent sequences to vec_sel()
           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: ---

Something like this:

xi = xi & ~is_subnormal;
xi |= subnormal & is_subnormal;

should be converted to:

xi = sel_vec(xi, subnormal, is_subnormal);
