Ah John one more thing, you may want to combine
SelectionDAGBuilder.diff<http://avr-llvm.svn.sourceforge.net/viewvc/avr-llvm/llvm/trunk/patches/SelectionDAGBuilder.diff?sortby=date&view=log>and
TargetCallingConv.diff<http://avr-llvm.svn.sourceforge.net/viewvc/avr-llvm/llvm/trunk/patches/TargetCallingConv.diff?sortby=date&view=log>into
one file since they both are used for the same purpose, you can name
the patch SplitArgPiece
