These caused LNT failures due to new assertions when running with -polly-position=before-vectorizer -polly-process-unprofitable for: FAIL: clamscan.compile_time FAIL: cjpeg.compile_time FAIL: consumer-jpeg.compile_time FAIL: shapes.compile_time FAIL: clamscan.execution_time FAIL: cjpeg.execution_time FAIL: consumer-jpeg.execution_time FAIL: shapes.execution_time The failures have been introduced by r264782, but r264789 had to be reverted as it depended on the earlier patch. llvm-svn: 264885 |

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.
