| =========================================== |
| |
| In Polly |version| the following important changes have been incorporated. |
| |
| .. only:: PreRelease |
| |
| .. warning:: |
| These release notes are for the next release of Polly and describe |
| the new features that have recently been committed to our development |
| branch. |
| |
| |
| - Support for -polly-vectorizer=polly has been removed. Polly's internal |
| vectorizer is not well maintained and is known to not work in some cases |
| such as region ScopStmts. Unlike LLVM's LoopVectorize pass it also does |
| not have a target-dependent cost heuristics, and we recommend using |
| LoopVectorize instead of -polly-vectorizer=polly. |
| |
| In the future we hope that Polly can collaborate better with LoopVectorize, |
| like Polly marking a loop is safe to vectorize with a specific simd width, |
| instead of replicating its functionality. |
| |
| - Polly-ACC has been removed. |
