As specified in the docs, 1) raw_string_ostream is always unbuffered and 2) the underlying buffer may be used directly ( 65b13610a5226b84889b923bae884ba395ad084d for further reference ) * Don't call raw_string_ostream::flush(), which is essentially a no-op. * Avoid unneeded calls to raw_string_ostream::str(), to avoid excess indirection.
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.
