[PATCH] D31033: [Polly] Add -polly-prune-unprofitable pass.

[Michael Kruse via Phabricator via llvm-commits]

Meinersbur added a comment.

The reason it is not default is that it is useless without having DeLICM/Simplify enabled as well.

We can think about turning them all on by default when the chain starts being useful. At least known-value for DeLICM should be in it. Before then, we can test individual parts by using -polly-enable-*.
