Ah, the cast from int field5 to v4df? Yes, that doesn't look right to me. Is this what you're talking about? It seems to me that gcc should emit a warning about this and/or not assume that &field5 is aligned to 32 bytes, as there is nothing in the source specifying such alignment. If it's an illegal program, gcc should at least emit a warning, if not an error. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45600
