- public abstract class WriteBarrierConstElim
- extends Simplification
WriteBarrierConstElim
eliminates write barriers
on MOVEs that are assigned from constants. Constant
propagation should probably be run beforehand for this pass
to make a difference.
This pass must be run before WriteBarrierTreePass
to have any effect.
