            Bug ID: 122826
           Summary: OpenMP SIMD call vectorization has incomplete SLP
                    support for linear() and uniform() clauses
           Product: gcc
           Version: 16.0
            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: ---

vectorizable_simd_clone_call analyzes only arguments of the first call in the
SLP node (actually that of the representative).  That should result in
wrong-code for uniform() and linear().

No testcase but I'm testing a workaround (disable multi-lane SLP for those
cases).
