            Bug ID: 87708
           Summary: ira-shrinkwrap-prep-[12].c testcases fail after
                    r265398
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: rtl-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: segher at gcc dot gnu.org
  Target Milestone: ---

These fail on many targets, and simply because the
split_live_ranges_for_shrink_wrap code can only move direct copies from the
hard argument registers, but they now usually are move to a pseudo first.

Ideally this code will improve, but in the meantime, maybe we should xfail
the test?
