niravd added a comment.

Looks google fine modulo the noted issues with load.



================
Comment at: lib/Target/X86/X86ISelLowering.cpp:31800
+    APInt SrcElts = APInt::getNullValue(NumElts);
+    for (int i = 0; i != NumElts; ++i) {
+      int M = OpMask[i];
----------------
Use OpMask[i]-Lo for M and merge the nested if conditions.
