I looked at the big diff between that and mainline, and couldn't make heads 
nor tails of it in the half-hour I spent on it.  I also looked at the svn 
history, but there's apparently a year and change of it.

I don't suppose there's a design document somewhere?  Or could you quickly 
explain "old one did this, new one does this, the code path diverges here, 
start reading at this point and expect this and this to happen, and if you go 
read this unrelated documentation to get up to speed it might help..."

I'd like to add enough of the new code generation stuff to the existing 
targets so it doesn't break when built with gcc4, but so far my interest here 
greatly outstrips my ability.  I don't even know where to start...
