Re: Defer register reading from remote target until needed?

It's supposed to work that way already. Either something's broken, or some register other than the ones you named *is* needed. The 'g' pkt should only go out if gdb needs the value of a register that it doesn't already have.

This can sometimes happen 'indirectly', eg. if you try to set a register, gdb may try to read it first.

Try setting a breakpoint in remote_fetch_registers, then go up
the stack and see what register gdb is trying to read.

Ah; it's because we need the subroutine return pointer when unwinding the pc. Thanks.
