Enabling -keep-going in ScopDetection causes expansion to an invalid Scop candidate. Region A <- Valid candidate | Region B <- Invalid candidate If -keep-going is enabled, ScopDetection would expand A to A+B because the RejectLog is never checked for errors during expansion. With this patch only A becomes a valid Scop. llvm-svn: 211875 |

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.
