ReportLoopHasNoExit started failing after r310940 that added infinite loops to postdominators. The change made regions not contain infinite loops anymore. This patch unbreaks the polly tree by XFAILING the ReportLoopHasNoExit test. Full fix is under review in D36776. llvm-svn: 310980
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.
