Re: [RFA] OSF/1 - "next" over prologueless function call

So the following test fails in infrun.c:handle_inferior_event() fails,
and GDB incorrectly thinks that we have landed at the next line of code:

  if (((stop_pc == ecs->stop_func_start /* Quick test */
        || in_prologue (stop_pc, ecs->stop_func_start))
       && !IN_SOLIB_RETURN_TRAMPOLINE (stop_pc, ecs->stop_func_name))
      || IN_SOLIB_CALL_TRAMPOLINE (stop_pc, ecs->stop_func_name)
      || ecs->stop_func_name == 0)


See my recent comments further down in that file. I think GDB should be using:

frame_id_unwind(current_frame) == frame_id_from_before_stepi

to determine if it did a step into a function. What happens if that is used?
