This is a case similar to PR22037, see execute_function_todo, passes calling
cleanup_tree_cfg need to expect to update SSA form.
bool cleanup = cleanup_tree_cfg ();
if (cleanup && (cfun->curr_properties & PROP_ssa))
flags |= TODO_remove_unused_locals;
/* When cleanup_tree_cfg merges consecutive blocks, it may
perform some simplistic propagation when removing single
valued PHI nodes. This propagation may, in turn, cause the
SSA form to become out-of-date (see PR 22037). So, even
if the parent pass had not scheduled an SSA update, we may
still need to do one. */
if (!(flags & TODO_update_ssa_any) && need_ssa_update_p (cfun))
flags |= TODO_update_ssa;
the reasoning here is similar.
