Class AssemblyLabels

java.lang.Object

org.adoptopenjdk.jitwatch.model.assembly.AssemblyLabels

public final class AssemblyLabels
extends Object

Calculate symbolic names for method-local addresses.

Operates in two modes. During parsing, newInstruction(AssemblyInstruction) accumulates addresses used by instructions. After all the instructions have been parsed, buildLabels() builds an index of addresses of all known instructions to label numbers, and formatAddress(long, StringBuilder) and formatOperands(AssemblyInstruction, StringBuilder) replace matching addresses with their labels.
