[PATCH] D96399: [X86][CodeGenPrepare] Try to reuse IV's incremented value instead of adding the offset

[Nikita Popov via Phabricator via llvm-commits]

>From a cursory look, the problem is likely that you're doing an unconditional call to getDT(), which will lead to unnecessary DomTree calculations. The way this function is supposed to be used is directly when checking dominance, after other checks have already been done.
