Due to bad habit we sometimes used a variable %defaultOpts that listed a set of passes commonly run to prepare for Polly. None of these test cases actually needs special preparation and only two of them need the 'basicaa' to be scheduled. Scheduling the required alias analysis explicitly makes the test cases clearer. llvm-svn: 211671 |

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.
