The aosp-O3-polly-before-vectorizer-unprofitable buildbot currently fails in ZoneAlgorithm::isNormalized, presumably because an out-of-quota happens in that function. Modify ZoneAlgorithm::isNormalized to return an isl::boolean such it can report an error. In the failing case, it was called in an assertion in ForwardOpTree. Allow to pass the assertion in an out-of-quota event, a condition that is later checked before forwarding an operand tree. llvm-svn: 333709 |

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.
