org.ek9lang.compiler.backend.jvm.LabelInstrAsmGenerator

All Implemented Interfaces:

Consumer<LabelInstr>

public final class LabelInstrAsmGenerator
extends AbstractAsmGenerator
implements Consumer<LabelInstr>

Specialized ASM generator for LabelInstr processing. Handles LABEL operations - marks instruction positions as branch targets for control flow operations like BRANCH_TRUE, BRANCH_FALSE, and BRANCH.

Method Details

accept

public void accept(LabelInstr labelInstr)

Generate JVM label placement for a label instruction. Uses the label cache in MethodContext to ensure the same JVM Label object is used for both label definition and branch targets.
