Also If we use vector_size rather than mode, we don't crash: typedef int __m64 __attribute__ (( vector_size(8) )); int foo() { return (long long)(__m64)(0ll); } -- What |Removed |Added ---------------------------------------------------------------------------- Known to fail|3.4.0 4.0 |3.4.0 4.0.0 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=16104
