Update CodegenCleanup using the function-level passes added by populatePassManager that run between EP_EarlyAsPossible and EP_VectorizerStart in -O3. The changes in particular are: - Added pass create arguments, e.g. ExpensiveCombines for InstCombine. - Remove reroll pass. The option -reroll-loops is disabled by default. - Add passes run with UnitAtATime, which is the default. - Add instances of LibCallsShrinkWrap, TailCallElimination, SCCP (sparse conditional constant propagation), Float2Int that did not run before. - Add instances of GVN as in the default pipeline. Notes: - GVNHoist, GVNSink, NewGVN are still disabled in the -O3 pipeline. - The optimization level and other optimization parameters are not accessible outside of PassManagerBuilder, hence we cannot add passes depending on these.

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.
