            Bug ID: 107896
           Summary: ICE in supportable_widening_operation, at
                    tree-vect-stmts.cc:12199 breaking arm bootstrap
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---

The following fails (reduced from arm bootstrap):

  int x_flag_tree_sink;
  int x_flag_tree_slp_vectorize;
  int x_flag_web;
} cl_optimization_restore_opts;
signed char cl_optimization_restore_ptr_1, cl_optimization_restore_ptr_0;
void cl_optimization_restore() {
  cl_optimization_restore_opts
      .x_flag_tree_phiprop = cl_optimization_restore_opts.x_flag_tree_pre =
      cl_optimization_restore_opts.x_flag_tree_pta =

                          cl_optimization_restore_ptr_0;
  cl_optimization_restore_opts.x_flag_web = cl_optimization_restore_ptr_1;
}
