          org.jikesrvm.compilers.opt.ssa.SSATuneUp

public final class SSATuneUp
extends OptimizationPlanCompositeElement
extends OptimizationPlanCompositeElement

This phase puts the IR in SSA form and performs a set of simple optimizations to clean up.

Nested Class Summary
`private static class`	`SSATuneUp.FoldingDriver` This class drives expression folding.
`static class`	`SSATuneUp.TuneUpPreparation` This class sets up the IR state prior to entering SSA.

Constructor Summary
`SSATuneUp()` Build this phase as a composite of others.

Method Summary
`boolean`	`shouldPerform(OptOptions options)` Determine, possibly by consulting the passed options object, if this optimization plan element should be performed.
