implementation of optimization phase? Books? Papers?

Hi,


Can you tell me a nice textbook that describes heuristic methods for
compiler optimization? I'm actually trying to build an optimizer for
arbitrarily-sized input syntax trees. I have several cost functions that
relate latency, perturbation, consistency, and frequency. I'm especially
interested in how to represent these costs in the intermediate
representation of the compiler while evaluating the alternative scenarios.
I think I understand the high level stuff, but a lower level description
of which data structs to use as well as how to develop and evaluate
different cost functions would really help.


Can you point me to any existing work? Thanks.
