Correct.
I'm looking for an algorithm to analyze bit swizzling requirements and
generate optimal code for them given the capabilities and constraints of
various ISAs.

This is part of my CAlive project. I'm looking for an algorithm which
already has the logic worked out, rather than (re-)inventing myself.
Note: I originally cross-posted this to comp.compilers yesterday, but
John Levine did not allow it to post. I reply here only to the
other group he cross-posted to originally, comp.arch.
