The amount of optimization that comes from -O3 -march=... versus running without those options provides a far greater performance benefit than going and further tweaking the flags.
-fmemorize-lookups and -fsave-memorized have been obsolete a VERY long (ditto for their original misspelling of memoize-lookups). Gcc and G++ refuse to compile code if you try to use them now, and afaik this has been the case since they were removed way back in the days of egcs. The genflags programs has specific hooks and support for adding in whatever flags you want into it's database. When a given flag can be proved definetiely safe then it can be a candidiate for the database. -- Robin Hugh Johnson E-Mail : [EMAIL PROTECTED] Home Page : http://www.orbis-terrarum.net/?l=people.robbat2 ICQ# : 30269588 or 41961639 GnuPG FP : 11AC BA4F 4778 E3F6 E4ED F38E B27B 944E 3488 4E85
