            Bug ID: 104296
           Summary: MIN<unsigned, 1> should simplify to unsigned != 0
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Keywords: missed-optimization
          Severity: enhancement
          Priority: P3
         Component: middle-end
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pinskia at gcc dot gnu.org
  Target Milestone: ---

Take:
unsigned t(unsigned a)
{
    unsigned b = 1;
    return a >= b ? b : a;
}

unsigned t1(unsigned a)
{
    return a >= 1 ? 1 : a;
}

These two functions are the same but currently they do not optimize to the same
thing.
