-O3 Optimize yet more. -O3 turns on all optimizations specified by -O2
and also turns on the -finline-functions, -funswitch-loops and
-fgcse-after-reload options.
So "-O3" is adding 3 more optimization flags to the bunch of flags "-O2"
brings. I thing it is reasonable to doubt that a program compiled with
"-O3" would greatly outperform the same program compiled with "-O2". The
same logic is applicable about stability. I have to admit that my logic
here is a plain arithmetic of type: "1 lemon - 10 cents, 10 lemons - 100
cents". There are programmers here who's opinion should be respected if
it differs from this logic.
