We only ever use the wrapped domain of AccessSchedule, so stop creating an entire union_map and then pulling the domain out. Reviewers: grosser Tags: #polly Contributed-by: Siddharth Bhat <siddu.druid@gmail.com> Differential Revision: https://reviews.llvm.org/D30179 llvm-svn: 295726 |

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.
