Instead of returning a pointer to the domain, we return a new copy of it. This is safer, as we do not give access to internal objects. It is also not expensive, as isl will just increment a reference counter. llvm-svn: 131010 |

Polly - Polyhedral optimizations for LLVM 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.
