ISL with small integer optimization requires C99 to compile. gcc < 5.0 still uses C89 as default, so we need to enable the options to compile in C99 mode. This patch is preparing the actual activation of small integer optimization. Differential version: http://reviews.llvm.org/D10610 Reviewers: grosser llvm-svn: 240322 |

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.
