Squeeze is a post-link-time optimizer that removes unreachable
code. It includes some very sophisticated analyses, but also some
simpler analyses that we have implemented in post-link-time tools that
take only some seconds and result in 20% code elimination. The system
is written for Alpha code, but is generally applicable. It achieves
roughly the same result on Compaq and gcc compiled code.


You'll find more information at the Squeeze site:
