The rs6000 contains this:
  if (lim_pc == 0)
    lim_pc = refine_prologue_limit (pc, lim_pc);
which I believe scores as a ``Not not true'' :-)

More seriously, what's the case you've encountered?

GDB should be using the dwarf2 debug info when setting the prologue breakpoint[s], how hard is it to do that?

PS: I'd keep the two comments separate, M-w or indent will merge them :-)
