Moved addInvariantLoads and functions listed below to ScopBuilder: isAParameter canAlwaysBeHoisted These functions were referenced only by getNonHoistableCtx. Moved CLI parameter PollyAllowDereferenceOfAllFunctionParams to ScopBuilder. Added iterator range through InvariantEquivClasses. Patch by Dominik Adamski <adamski.dominik@gmail.com> Differential Revision: https://reviews.llvm.org/D63172 llvm-svn: 363216
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.
