ScopBuilder distributes independent instructions between statements. Only modeled (e.g. not synthesizable) instructions are represented. To compute independence, non-modeled instructions were used in some parts of determining instruction independence, which could lead to the re-introduction of non-model instructions. In particular, required invariant loads could be added to instruction list, which then led to redundant MemoryAccesses for such a load. This fixes llvm.org/PR48059. |

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.
