![]() Now that SimpleLoopUnswitch and other transforms no longer introduce branch on poison, enable the -branch-on-poison-as-ub option by default. The practical impact of this is mostly better flag preservation in SCEV, and some freeze instructions no longer being necessary. Differential Revision: https://reviews.llvm.org/D125299 |

Polly - Polyhedral optimizations for LLVM ----------------------------------------- http://polly.llvm.org/ Polly uses a mathematical representation, the polyhedral model, to represent and transform loops and other control flow structures. Using an abstract representation it is possible to reason about transformations in a more general way and to use highly optimized linear programming libraries to figure out the optimal loop structure. These transformations can be used to do constant propagation through arrays, remove dead loop iterations, optimize loops for cache locality, optimize arrays, apply advanced automatic parallelization, drive vectorization, or they can be used to do software pipelining.
