Search for this:
Allen Leung and Lal George:
Some notes on the new MLRISC X86 floating point code generator.
Note that although this paper assumes only 7 pseudo registers, it also works
Moreover, the x87 simulator in libFirm (www.sf.net/project/libfirm) should
have some hopefully understandable comments regarding this technique :-).
