(forward_propagate_addr_into_variable_array_index): Likewise. (forward_propagate_addr_expr): Likewise. (tree_ssa_forward_propagate_single_use_vars): Likewise. (forward_propagate_addr_expr_1): Recurse on simple copies instead of propagating into them. Do so for useless conversions as well. (forward_propagate_addr_expr): Clean up unused statements after recursion. * g++.dg/tree-ssa/pr31146.C: New testcase.
