llvm-mirror/test/CodeGen/X86/mmx-arith.ll
Craig Topper 1c3f74bc5b [X86] Add custom type legalization for v2i32/v4i16/v8i8->mmx bitcasts to avoid a store/load to/from the stack. 
Widen the input to a 128 bit vector by padding with undef elements. Then use a movdq2q to convert from xmm register to mmx register.
