Also un-revert (isl_pw_*_alloc: add missing check for compatible spaces, Wed Sep 6 12:18:04 2017 +0200). This patch is a proposed fix to avoid asserts due to stricter space checking within isl, which resulted in failures when converting a schedule tree to a schedule map. llvm-svn: 326073 |

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.
