Michael Kruse fbde435517 [CodeGen] Use MapVector instead of DenseMap. The map is iterated over when generating the values escaping the SCoP. The indeterministic iteration order of DenseMap causes the output IR to change at every compilation, adding noise to comparisons. Replace DenseMap by a MapVector to ensure the same iteration order at every compilation. llvm-svn: 277832		2016-08-05 16:45:51 +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.
