[PATCH] D57033: [LCSSA] Handle case with single new PHI faster.

[Florian Hahn via Phabricator via llvm-commits]

fhahn updated this revision to Diff 183503.
fhahn added a comment.

Update LCSSA llvm.dbg.value test case with 2 additional interesting cases: a llvm.dbg.value call in a block without a placed PHI, but a use re-written by SSAUpdater and a llvm.dbg.value call we cannot rewrite, because it was not visited by SSUpdater (because it is 'after' all rewritten uses).
