BarrierSetAssembler::nmethod_entry_barrier currently uses a comparison and an explicit call to StubRoutines::method_entry_barrier(). We could replace it by a conditional trap instruction and dispatch to the stub in the signal handler. The old code should still be usable. The new code could be made available by a new diagnostic flag similar to e.g. TrapBasedICMissChecks.
