This gets very expensive for basic blocks which don't have a name: it calls printAsOperand, which numbers the entire module. We don't normally need the name anyway, though; it's only used for debug dumps, so don't compute it by default. Differential Revision: https://reviews.llvm.org/D44946 llvm-svn: 328666 |

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.
