Even before we build the domain the branch condition can become very complex, especially if we have to build the complement of a lot of equality constraints. With this patch we bail if the branch condition has a lot of basic sets and parameters. After this patch we now successfully compile External/SPEC/CINT2000/186_crafty/186_crafty with "-polly-process-unprofitable -polly-position=before-vectorizer". llvm-svn: 265286 |

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.
