Class Summary

Class	Description
BasicRegisterMapper	This class maps one register space into another, with each mapping built up individually and added via addMapping()
ConstCollector	Collects constants that are used more than once at the top of the method block.
DeadCodeRemover	A variation on Appel Algorithm 19.12 "Dead code elimination in SSA form".
DomFront	Calculates the dominance-frontiers of a method's basic blocks.
DomFront.DomInfo	Dominance-frontier information for a single basic block.
Dominators	This class computes dominator and post-dominator information using the Lengauer-Tarjan method.
EscapeAnalysis	Simple intraprocedural escape analysis.
InterferenceRegisterMapper	A register mapper that keeps track of the accumulated interference information for the registers in the new namespace.
LiteralOpUpgrader	Upgrades insn to their literal (constant-immediate) equivalent if possible.
LocalVariableExtractor	Code to figure out which local variables are active at which points in a method.
LocalVariableInfo	Container for local variable information for a particular SsaMethod.
MoveParamCombiner	Combine identical move-param insns, which may result from Ropper's handling of synchronized methods.
NormalSsaInsn	A "normal" (non-phi) instruction in SSA form.
Optimizer	Runs a method through the SSA form conversion, any optimization algorithms, and returns it to rop form.
PhiInsn	A Phi instruction (magical post-control-flow-merge) instruction in SSA form.
PhiTypeResolver	Resolves the result types of phi instructions.
RegisterMapper	Represents a mapping between two register numbering schemes.
SCCP	A small variant of Wegman and Zadeck's Sparse Conditional Constant Propagation algorithm.
SetFactory	Makes int sets for various parts of the optimizer.
SsaBasicBlock	An SSA representation of a basic block.
SsaBasicBlock.LabelComparator	Label comparator.
SsaConverter	Converts ROP methods to SSA Methods
SsaInsn	An instruction in SSA form
SsaMethod	A method in SSA form.
SsaRenamer	Complete transformation to SSA form by renaming all registers accessed.
