[PATCH] D33487: [Polly][DeLICM] Partial writes for PHIs.

[Michael Kruse via Phabricator via llvm-commits]

Meinersbur created this revision.
Meinersbur added a project: Polly.

Enable the use for partial writes for PHI write accesses with a switch. This simply skips the test for whether a PHI write would be partial.

The analog test for partial value writes also protects for partial reads which we do not support (yet). It is possible to test for partial reads separately such that we could skip the partial write check as well. In case this shows up to be useful, I can implement it as well.
