By just removing dimensions (and the constraints they are involved in) we may loose information about the dimensions we do not remove. By instead using project_out, we are sure all constraints on the outer dimensions are preserved. No test case, as this error condition is very unlikely to be triggered by isl's current code. We still 'fix' this, as isl gives little guarantees regarding the behavior of remove_divs. llvm-svn: 246567 |

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.
