[PATCH] D79850: [mlir] Extended BufferPlacement to support more sophisticated scenarios in which allocations cannot be moved freely and can remain in divergent control flow.

[Marcel Koester via Phabricator via llvm-commits]

dfki-mako updated this revision to Diff 266480.
dfki-mako added a comment.

Fixed corner cases in which no copies have been created due to aliasing (see reviewer comments).
Added additional test cases to simulate such special control-flow scenarios.
Changed behavior of the BufferPlacement pass to ignore Alloc operations with multiple allocation results.
