[PATCH] D93615: [LV] Avoid needless fold tail

[Sjoerd Meijer via Phabricator via llvm-commits]

SjoerdMeijer added inline comments.


================
Comment at: llvm/lib/Transforms/Vectorize/LoopVectorize.cpp:5505
       UserIC ? MaxVF.getFixedValue() * UserIC : MaxVF.getFixedValue();
   if (TC > 0 && TC % MaxVFtimesIC == 0) {
     // Accept MaxVF if we do not have a tail.
----------------
Was surprised to see this change, because I thought we were handling it here already.
Is this check here still relevant? Or can we "merge" this with the one that you added below?
