"Write" is an overloaded term. In collectInfo() till buildFlow(), it is used to mean "must writes". However, within the memory based analysis, it is used to mean "both may and must writes". Renaming the Write variable helps clarify this difference. Reviewers: grosser Tags: #polly Differential Revision: https://reviews.llvm.org/D31181 llvm-svn: 298361
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.
