duncantl/Rllvm: Interface to llvm for dynamically compiling native code.
Version 0.7-0

This package is currently an interface to some of the functionality in the llvm toolkit for programmaticall constructing native code. This allows us to build "compilers" in R and use llvm's optmization and JIT techniques to improve the code we generate and then turn it into machine code. This is currently not a compiler. There are examples that illustrate how to generate code to create native functions that are equivalent to some simple R functions. The goal is to build on this and create a compiler, hopefully building on the framework that Luke Tierney has created in his compiler package (see http://www.cs.uiowa.edu/~luke/R/compiler/). This is in the RLLVCompile package. The speed up we achieve compiling R code in our examples illustrate that we can significantly outperform the R interpreter and also can outperform some of R's vectorized code by rearranging the computations, e.g. fusing loops, avoiding memory usage.
