No, not really. -O1 disables ``expensive optimizations'',
i.e. optimizations that use significant portions of processor time.
Thus, which optimizations are selected for inclusion in -O1 has
nothing to do with which ones defeat debugging, and the fact that -O1
compiled programs are easier to debug is a pure coincidence. I'm
quite sure several important optimizations could be added to -O1
without any significant effect on debuggability.
