Norman Adams turned his assembler into a master's degree. It also was a
   cool piece of software. His assembler didn't take a linear text stream;
   the compiler handed it a *graph structure*. It serialised the graph on
   its own to minimise the spans of the jump instructions, and had other
   neat features (e.g., it was actually a portable framework for building
   assemblers).

I can't find this thesis anywhere. Does any body have a copy?
