Some Polly ACC test cases fail without a working NVPTX backend. We explicitly specify this dependence in REQUIRES. Alternatively, we could have only marked polly-acc as supported in case the NVPTX backend is available, but as we might use other backends in the future, this does not seem to be the best choice. For this to work, we also need to make the 'targets_to_build' information available. Suggested-by: Michael Kruse <llvm@meinersbur.de> llvm-svn: 296853 |

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.
