In a remote debug session, how do I get to see fresh register values each time I do a 'show all-registers'?

  flushregs is exactly what I needed. Thank you. (Looking it up also made
  me aware of Appendix C: Maintenance commands).

  In the first case, please note that I *do* see behaviour as expected.
  (Sorry about not being clear, I should perhaps have worded it thus:
  "To begin with, I can read the values of the GPR's in the simulator
  and upon a 'show all-registers', I do see that the registers have
  values as expected. Then, later on, as the program (viz. linux) runs,
  and the simulator displays the changed register values, I issue a
  'show all-registers' again in GDB, hoping to see the new register
  values that the simulator now displays, but GDB continues to display
  the old values it displayed). [=> flushregs].
