We use llvm.codegen intrinsic to generate code for embedded LLVM-IR strings. The reason we introduce such a intrinsic is that previous clang/opt tools was NOT linked with various LLVM targets and their AsmParsers and AsmPrinters. Since clang/opt been linked with all the needed libraries, we no longer need the llvm.codegen intrinsic. llvm-svn: 211573 |

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.
