public final class PeepholeOptimizingClassVisitor
extends org.objectweb.asm.ClassVisitor

Class-level installation point for Groovy's single-pass bytecode peephole layer.

Wraps each org.objectweb.asm.MethodVisitor returned by the delegate's visitMethod(int, String, String, String, String[]) with PeepholeOptimizingMethodVisitor, so every method body receives the same stack-local compaction — user methods, constructors, static initializers, and synthetic helpers alike (MOP bridges, call-site array initializers, class$/$get$ resolvers, large-list init chunks, and so on).

Centralizing the wrap here avoids ad-hoc new PeepholeOptimizingMethodVisitor(...) at individual emission sites and keeps compaction in lockstep with OperandStack, which emits integer and other primitive constants via visitLdcInsn and relies on the peephole visitor to narrow them to ICONST_*, BIPUSH, SIPUSH, etc.

Installed once by WriterController when the class visitor chain is built (optionally outside a LoggableClassVisitor / TraceClassVisitor pair used for classgen logging). Field and attribute visits are left unchanged; only method bodies are optimized.
