No. You can get method-level tracing with --trace, and the built-in ARM/MIPS simulators can trace simulated machine instructions with --trace-sim.
If you really need tracing with the granularity of AST nodes or similar, it would probably be easier to use a JS engine that can run in purely interpreted mode.
