- Instead of running with -O0, we enable the highest optimization level, but then disable optimizations. This ensures that possibly important metadata is still emitted. - Update the code for attribute removal to work with latest LLVM - Do not cut an arbitrary number of lines from the LL file. It is undocumented why this was needed at the first place, and such a feature is likely to break with trivial IR changes that may come in the future. llvm-svn: 307355 |

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.
