We can only link against libLLVM.so or the individual libLLVM*.so components, but not both of them. Doing so results in these components exist twice in the programs address space, since it is already contained in libLLVM.so. The observable effect of this is that command line switches are registered multiple times (once for each instance), which is an error. This fixes llvm.org/PR32735.

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.
