Hi:
I use "set architecuture xxx" command to change arch for my gdbserver,
and I've traced that, gdb will send a g_packet to gdbserver to fetch
registers' values, and then do some correct-pc-things.
But, if I input the "set arch xxx" command right after the "continue"
command, the value of EIP will always be wrong, it points to the
instruction after the correct one. Why?

Hi.
I wouldn't expect one to be able to change the arch after the inferior
has started.
It's hard to provide much help in the absence of an example session
showing the problem.
One can only guess ...
