Hi all,
The command "java -XX:+UnlockDiagnosticVMOptions -XX:+PrintInterpreter" can be used to print a disassembly of the HotSpot interpreter.
In [JDK-8204267](https://bugs.openjdk.org/browse/JDK-8204267), the interpreter generate comments to link the instructions back to the C++ source code that generates them, but the releated PR only support x86 backend, I think it's doable on aarch64 either.
Additonal testing:
- [ ] aarch64 native build with slowdebug and fastdebug
- [ ] jtreg tests(include tier1/tier2/tier3 etc.) with release build
