You might want to check out Jones, Gomard and Sestoft, `Partial
Evaluation and Program Specialisation', Prentice Hall 1993. It gives
a pretty thorough and comprehensible grounding in the current state of
the art in partial evaluation, and has a fair-sized bibliography at
the back.


For what it's worth, I think the overhead involved in learning about
partial evaluation techniques is probably not justified for a single
project. I think David Keppel's papers on RTCG and instruction set
simulation and those they reference (Bedichek's 88000 simulator in
particular) provide more immediately accessible techniques, if you
want to dynamically translate your code in an efficient manner. See
David's recent postings here for further details.
