    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.

In practice, though, does it really make a difference?
Why won't using -O1 be good for you?
Do you really need the extra performance of those
optimizations that could be added?
