stream

a logical value indicating whether to release/garbage
 collect the raw stream <code>stream</code>.

delete

a logical value to indicate whether to register a
 finalizer for the stream

finalize

an initial string, typically empty

value

the name of the file to which the contents should be written

filename

These functions allow us to create and use LLVM output streams
 for generating content, e.g. code.

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.
