How to debug native android runtime(ART) module fast through gdb/lldb etc.?

Question

I run android system on my linux with emulator, and now I want to debug android runtime(ART).
I can debug through the following methods now:

1. first replace the system's libart with debug_info library.

emulator
adb root
adb remount
adb push ~/android/library/libart.so /system/lib/libart.so

2. Then perform port forwarding within the Android system, and use gdbserver to listen within the Android system, using calendar applications as an example:

adb forward tcp:2345 tcp:2345
adb shell gdbserver 10.0.2.2:2345 am start -n com.android.calendar/com.android.calendar.LaunchActivity

3. Use gdb to connect to gdbserver in host system and debug libart:

target remote :2345
dir ~/android/aosp/
b JNI_CreateJavaVM
r

But debugging ART in this way is very inconvenient. Is there a better debug method available?
