I did this some time ago, and found it pretty much a waste of time as far
as optimizing GNU Go is concerned. The reason is that GNU Go's performance
is 90 % bound by branch-misprediction, and that you cannot optimize
these branches away. Btw I was told that the same held true for the
version of Many Faces that David Fotland had submitted to SPEC95, and I
would not be surprised if that is true for any go program.
