    * tree-tailcall.c (process_assignment): Handle POINTER_PLUS_EXPR.
    (find_tail_calls): Give up for pointer result types if m is non-NULL.
    (adjust_return_value_with_ops): For PLUS_EXPR and pointer result type
    emit POINTER_PLUS_EXPR.
    (create_tailcall_accumulator): For pointer result type accumulate in
    sizetype type.

    * gcc.c-torture/execute/pr58209.c: New test.
