The patch moves out of SCEV's scope so they can be re-used for SCEVUse. SCEVUse gets an additional getNoWrapFlags helper that returns the union of the expressions SCEV flags and the use-specific flags. SCEVExpander has been updated to use this new helper. In order to avoid other changes, the original names are exposed via constexpr in SCEV. Not sure if there's a nicer way. One alternative would be to define the enum in struct, and have SCEV inherit from it. The patch also clarifies that the SCEVUse flags encode NUW/NSW, and hides getInt, setInt, etc to avoid potential mis-use. PR: https://github.com/llvm/llvm-project/pull/190199 |

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.
