  coins.ssa.AggregateInstructions

class AggregateInstructions

extends java.lang.Object

Aggregate LIR trees.
There are some optimizations to break LIR trees many pieces. with the temporary variables. Unfortunately it may be disadvantage for good code generation. So, the SSA module aggregates LIR trees again. If the temporary varaibles refers only once, this optimizer fills the expression instead of the temporary variable.
