[PATCH] D98898: [SimplifyCFG] use profile metadata to refine merging branch conditions

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added inline comments.


================
Comment at: llvm/lib/Transforms/Utils/SimplifyCFG.cpp:3009-3012
 bool llvm::FoldBranchToCommonDest(BranchInst *BI, DomTreeUpdater *DTU,
                                   MemorySSAUpdater *MSSAU,
                                   const TargetTransformInfo *TTI,
                                   unsigned BonusInstThreshold) {
----------------
`FoldBranchToCommonDest()` might be called from outside of SimplifyCFG (it is called from loopsimplify), without passing-in TTI, i guess.
