[PATCH] D113609: [X86][Costmodel] `getReplicationShuffleCost()`: promote 16 bit-wide elements to 32 bit when no AVX512BW

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: llvm/lib/Target/X86/X86TargetTransformInfo.cpp:3644
+  // Do we have a native shuffle for this element type, or should we promote?
+  unsigned EffEltTyBits = EltTyBits;
   switch (EltTyBits) {
----------------
I assume 'Eff' is short for effective? But we talk about it in terms of promotion - can you use a consistent term, I don't mind which.
