--- Comment #2 from Marc Glisse <glisse at gcc dot gnu.org> 2013-04-01 15:14:59 UTC --- Created attachment 29767 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=29767 patch This patch may be a bit too strong. In particular, it breaks gcc.dg/vect/nodump-forwprop-22.c (although we might consider that it is forwprop that is too weak). Also, it doesn't put exactly __m128i* in the MEM_REF but instead long long* (s_1m* would be easy as well, but I don't know what property of __m128i makes it the right type so I can't teach that to the compiler). The forwprop bit is for PR55266 and not strictly necessary here.
