================
Comment at: llvm/lib/Transforms/Scalar/IndVarSimplify.cpp:1363
BranchInst *BI = cast<BranchInst>(ExitingBB->getTerminator());
Rewriter.setInsertPoint(BI);
auto *LHSV = Rewriter.expandCodeFor(LIP.LHS);
----------------
Shouldn't the Rewriter expand in the preheader as well? Can LHSV/RHSV ever *not* be loop invariant in this function?
