[PATCH] D34135: [JumpThreading] Use DT to avoid processing dead blocks

[Daniel Berlin via Phabricator via llvm-commits]

dberlin added a comment.

(also, the DT was not updated at all prior during JT prior to all of these patches, so i guess it all worked because LVI didn't use DT when called from JumpThreading or something)?
