------- Comment #12 from aoliva at gcc dot gnu dot org 2010-09-02 12:21 ------- 'been looking into this as well. cp/pt.c -fcompare-debug fails for me on x86_64-linux-gnu.
I'm not sure yet why we get different different types for the integer_csts in operand 0 of MEM_REFs, but it occurred to me that we could add a flag to operand_equal_p to check that all types are the same. Ideally, we'd have corresponding flags for hashing as well, but not necessarly for correctness. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45419
