[PATCH] D27756: [X86][SSE] Improve lowering of vXi64 multiplies

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: lib/Target/X86/X86TargetTransformInfo.cpp:556
     // Because we believe v4i64 to be a legal type, we must also include the
     // split factor of two in the cost table. Therefore, the cost here is 18
     // instead of 9.
