Thank you, I'll try it~
Hi YiXun
I think gdb scripts may help you for this problem
you can define a macro in .gdbinit file like this:
define hsbreak main
run -Xem:interpreter $arg0
break hysl_open_shared_library
continue
finish
disable
break jni.cpp:CallStaticVoidMethod
continue
break interpreter.cpp:Opcode_NEW #functions whatever you like
continue
dis
end
then, you can use this macro "hs" in your gdb command to set the breakpoint
and debug.
Thanks

Hi all,
I modified harmony to make it support ClassRedefine, but I got a
segmentation fault when called new to create an instance of
the new version class. I changed to interpreter mode, and found the problem
happened when executing OPCODE_INVOKESPECIAL.
case OPCODE_INVOKESPECIAL:
// Next line marks the
"P_TLS_vmthread->thread_exception" that an exception happened.
Opcode_INVOKESPECIAL(frame);
// get_current_thread_exception can not
handle the exception properly and cause the segment fault.
frame.exc = get_current_thread_exception();
I was using "printf" to locate the bug, but it is too complicated here. But
when I use gdb to trace the execution, it cannot follow the function
pointer "(*env)->CallStaticVoidMethod (env, cls, mid, args);" in main.c.
So, how can I use gdb to debug the interpreter? Thanks.
