Hi Jisheng,
Hi,

Would you be still working on this series?
I will rebase the implementation on the latest code, then try to address
your comments and Mark's comments. I will send out patches in this weekend.

If you are still want to put a probe on func+4, it is OK if you can
completely emulate the 1st instruction. (lr save on the stack and
change the regs->sp)
Will check which is the better solution.
Thanks Jisheng!

What I'm considering is the consistency of pre_handler()@addr and 
post_handler()@addr+4. Also, whether the value of regs (and stacks) is
same as the user expected.

Thank you,
