View registers from stack frames

I have only tested the --target=powerpc-eabi version so I don't know about
other processors. Is this true that gdb is supposed to show pc and lr with
the same values for stack frames >0? Isn't the purpose of the lr to point
to the previous stack frame (and so be different from the actual pc)?
And if the actual behaviour is correct then why is it different for frame 0?

Thanks
