[PATCH] D66529: [LOOPGUARD] Disable loop with multiple loop exiting blocks.

[Kit Barton via Phabricator via llvm-commits]

kbarton added a comment.

I don't remember why exactly this was necessary.
Looking at the current definition in LoopInfo.h, it's not immediately obvious to me either.
Could you either update the definition of getLoopGuardBranch in LoopInfo.h to state this case is not handled (and why). Or, if it's something obvious that I'm not seeing, expand the description here to make it clear?

Thanks.
