isl_map_from_union_map cannot determine the map's space if the union_map is empty. polly::singleton was designed for this case. We pass the expected map space to avoid crashing in isl_map_from_union_map. This fixes an issue found by the aosp buildbot. Thanks to Eli Friedman for the reproducer. llvm-svn: 361290 |

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.
