Instead of counting the number of read-only accesses, we now count the number of distinct read-only array references when checking if a run-time alias check may be too complex. The run-time alias check is quadratic in the number of base pointers, not the number of accesses. Before this change we accidentally skipped SPEC's lbm test case. llvm-svn: 295567 |

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.
