These verify that some scalars are not mapped because it would be incorrect to do so. For these check we verify that no transformation has been executed from output of the pass's '-analyze'. Adding optimization remarks is not useful as it would result in too many messages, even repeated ones. I avoided checking the '-debug-only=polly-delicm' output which is an antipattern. llvm-svn: 296348 |

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.
