This review is based on review: https://reviews.llvm.org/D62925 . It is part of moving hoistInvariantLoads function and all functions referenced only by hoistInvariantLoads to ScopBuilder. Moved getNonHoistableCtx and functions listed below to ScopBuilder: isRequiredInvariantLoad hasNonHoistableBasePtrInScop isAccessRangeTooComplex These functions were referenced only by getNonHoistableCtx. MaxDimensionsInAccessRange and MaxDisjunctsInDomain constant is marked as extern and it is added to polly namespace. It is used by Scop and ScopBuilder classes. MaxDimensionsInAccessRange constant moved to ScopBuilder. It is not used outside ScopBuilder.

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.
