Class ProfilingExitAsmGenerator

java.lang.Object

org.ek9lang.compiler.backend.jvm.AbstractAsmGenerator

org.ek9lang.compiler.backend.jvm.ProfilingExitAsmGenerator

All Implemented Interfaces:

Consumer<ProfilingExitInstr>, org.objectweb.asm.Opcodes

final class ProfilingExitAsmGenerator
extends AbstractAsmGenerator
implements Consumer<ProfilingExitInstr>, org.objectweb.asm.Opcodes

Specialized ASM generator for ProfilingExitInstr processing.

Generates bytecode to record function exit by calling ProfilingRuntime.exitFunction(long functionId). The runtime computes elapsed time and accumulates timing data.

Generated bytecode pattern (2 instructions per probe):

LDC2_W functionId                          (push long constant)
INVOKESTATIC org/ek9/lang/ProfilingRuntime.exitFunction(J)V
