            Bug ID: 116973
           Summary: FAIL: gcc.dg/vect/pr52252-st.c with forced SLP
           Product: gcc
           Version: 15.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: rguenth at gcc dot gnu.org
  Target Milestone: ---

This testcase shows (apart from being bad because of missed CSE due to aliasing
even though we use versioning for aliasing) that we fail to lower permutes for
SLP loads that only have a single load of a group which leads to

missed:   permutation requires at least three vectors _9 = MEM[(unsigned char
*)in_34 + 4B];
missed:   unsupported load permutation
