We now distinguish invariant loads to the same memory location if they have different types. This will cause us to pre-load an invariant location once for each type that is used to access it. However, we can thereby avoid invalid casting, especially if an array is accessed though different typed/sized invariant loads. This basically reverts the changes in r260023 but keeps the test cases. llvm-svn: 260045 |

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.
