[PATCH] D38916: [GlobalDCE] Use DenseMap instead of unordered_multimap for GVDependencies.

[Davide Italiano via Phabricator via llvm-commits]

davide added a comment.

Generally switching to generic containers to LLVM ones lead to improvements, but 17x seems quite large to me (not complaining).
I wonder if you can add a test (maybe to CTMark?) to make sure this doesn't regress.
