[PATCH] D130339: [CodeGen] Generate efficient assembly for freeze(poison) version of `mm*_cast*` intel intrinsics

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: llvm/lib/Target/X86/X86ISelLowering.cpp:11433
+                        : (NumFreezeUndef ? DAG.getFreeze(DAG.getUNDEF(ResVT))
+                                          : DAG.getUNDEF(ResVT));
 
----------------
Is there any reason we couldn't just always use DAG.getFreeze(DAG.getUNDEF(ResVT)) ?
