Class ProfilingExitInstr

java.lang.Object

org.ek9lang.compiler.ir.instructions.IRInstr

org.ek9lang.compiler.ir.instructions.ProfilingExitInstr

All Implemented Interfaces:

INode

public final class ProfilingExitInstr
extends IRInstr

Specialized IR instruction for profiling function exit (PROFILING_EXIT).

Profiling exit probes are inserted before function return when profiling is enabled. Each probe computes elapsed time and accumulates timing data.

The JVM backend wraps the method body in try/finally to ensure this fires even when exceptions occur.
