[PATCH] D83288: [LV] Pick vector loop body as insert point for SCEV expansion.

[Ayal Zaks via Phabricator via llvm-commits]

Ayal added a comment.

Good catch!

The specific culprit for the pr is the call to SE.DT.dominates(EntInst, InsertPt) by SCEVExpander::FindValueInExprValueMap().

Would probably be better to keep DT up to date as we go along, due to SE.DT's dependence on it, instead of fixing it after code-gen via updateDominatorTree(); but there was some reason for doing it this way(?).
