Does anyone know about any heuristics or algorithms for global
instruction scheduling that try not to schedule operations earlier
than necessary. Ideally, the heuristic should avoid delaying the
operation so much that it lengthens the schedule or causes it to be
duplicated by being pushed below a branch.

Thanks in advance for any ideas,
