The check-polly-tests target runs regression/unit tests but without checking formatting. This is useful to not having to reload a file in an open editor (which eg. clears the undo buffer, moves cursor/window position) when running polly-update-format. After this change, the following test targets exist: - check-polly-unittests to run unittests only - check-polly-tests to run unit and regression tests - polly-check-format to check formatting using clang-format - check-polly to run them all As a side-effect, when running check-polly, polly-check-format and run in parallel (instead of polly-check-format first).

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.
