llvm commonly adds a comment to the closing brace of a namespace to indicate which namespace is closed. clang-tidy provides with llvm-namespace-comment a handy tool to check for this habit. We use it to ensure we consitently use namespace comments in Polly. There are slightly different styles in how namespaces are closed in LLVM. As there is no large difference between the different comment styles we go for the style clang-tidy suggests by default. To reproduce this fix run: for i in `ls tools/polly/lib/*/*.cpp`; \ clang-tidy -checks='-*,llvm-namespace-comment' -p build $i -fix \ -header-filter=".*"; \ done This cleanup was suggested by Eugene Zelenko <eugene.zelenko@gmail.com> in http://reviews.llvm.org/D21488 and was split out to increase readability. llvm-svn: 273621 |

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.
