[PATCH] D106859: [Sink] allow sinking convergent operations across uniform branches

[Sameer Sahasrabuddhe via Phabricator via llvm-commits]

sameerds updated this revision to Diff 362995.
sameerds added a comment.

The change was rebased, which may produce a very noisy diff relative to
the previous version of the change.

Replaced the bool ContainsIrreducible with a new enum that is always
consistent, irrespective of whether we are using legacy DA or new DA.
This also allows a command-line option to force "divergent" control
flow, so that we can test changes on the default target for better
coverage.
