Continuing from http://sourceware.org/ml/gdb-patches/2012-04/msg01001.html
I am posting to gdb@ as it is more suitable now.

I didn't want to use $pc explicitly as the manual only says "on most
machines" with regard to its meaning.  I do not know of any machine
where PC does not mean the program counter though.

What are the other ways to get the value of the PC?

Thanks,
Siva Chandra

Yeah.

Siva> What are the other ways to get the value of the PC?

gdb.Frame.pc is the simplest.  You can pick any frame, but for commands
the selected frame is the one that users expect.
