[PATCH] D118066: [SimplifyCFG] Don't speculatively execute preductably-taken block

[Nikita Popov via Phabricator via llvm-commits]

Not sure on this. I think in theory you may be right, but in practice I suspect that converting a separate block into a select will on average be beneficial, because of the followup optimizations it enables. We'll be able to do more with a select than a whole basic block.
