^^^^^^
Would you care to explain to me just what the hell you think you are
achieving with "-O6"??? For one, no released version of GCC understands
anything above "-O3" (anything above 3 gets converted to 3). RTFM.
Have you done a single measure to see what the extra optimization is
buying you? OR do you just want to be macho and so you can tell everyone
your world is built with "-O6"? (As I stand up straight and stick out my
chest like a military man)
FreeBSD only officially supports building the OS with "-O". There are
optimizer bugs above that (and even sometimes with just -O).
