--- Comment #2 from wmi at google dot com --- Another problem is found in true_dependence_1 in alias.c. true_mem_addr or true_x_addr got after calling get_addr may be used as inputs of memrefs_conflict_p. However memrefs_conflict_p expects to use VALUE type nodes as its inputs, so the values of the memory addresses can be comparable. Only find_base_term and base_alias_check should use true_mem_addr/true_x_addr in true_dependence_1. This problem is not a correctness issue, but may affect the effectiveness of dse/postreload...
