<p>An LLVM context is used to manage data within the
  LLVM engine. One typically has a single context
  in a given thread when generating code.
  This is not typically an issue in R.</p>

programming

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.
