Phoronix: Embedding A Code Compiler With GPU Drivers  During the
X.Org meetings at FOSDEM, Stephane Marchesin had discussed what
he and other open-source developers are doing by using a code
compiler (LLVM) and interweaving it with the Gallium3D driver
architecture. By strapping the Low-Level Virtual Machine to
Gallium3D, developers are hoping they can use the power of this
relatively new compiler infrastructure to provide advanced GPU
shader optimizations. This is not exactly an easy task, but it
is believed it can be accomplished with beneficial results and
they are making progress.
