The existing code would add the operands in the wrong order, and eventually crash because the SCEV expression doesn't exactly match the parameter SCEV expression in SCEVAffinator::visit. (SCEV doesn't sort the operands to getMulExpr in general.) Differential Revision: https://reviews.llvm.org/D23592 llvm-svn: 279087 |

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.
