Sorry for the delay - I'm happy for this to go in as a first step, are you intending to continue investigating multiple insertions?



================
Comment at: llvm/lib/Target/X86/X86ISelLowering.cpp:19036
+        ((Subtarget.hasAVX2() && EltSizeInBits != 8) ||
+         (Subtarget.hasAVX() && (EltSizeInBits == 32 || EltSizeInBits == 64) &&
+          MayFoldLoad(N1)))) {
----------------
EltSizeInBits >= 32 ?
