Johannes Doerfert 43788c5783 Check for feasible runtime check context early Instead of generating code for an empty assumed context we bail out early. As the number of assumptions we generate increases this becomes more and more important. Additionally, this change will allow us to hide internal contexts that are only used in runtime checks e.g., a boundary context with constraints not suited for simplifications. llvm-svn: 245540		2015-08-20 05:58:56 +00:00

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.
