![]() Since the base pointer of a possibly aliasing pointer might not alias with any other pointer it (the base pointer) might not be tagged as "required invariant". However, we need it do be in order to compare the accessed addresses of the derived (possibly aliasing) pointer. This patch also tries to clean up the load hoisting a little bit. llvm-svn: 270412 |

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.
