I've used these in make.conf for a while with no problems, but your mileage may vary: CFLAGS=-O3 -pipe -funroll-loops -march=pentiumprp COPTFLAGS=-O3 -pipe -funroll-loops -fomit-frame-pointer -fno-builtin -march=pentiumpro CXXFLAGS+= -fmemoize-lookups -fsave-memoized -- Lars Eggert <larse@isi.edu> Information Sciences Institute http://www.isi.edu/larse/ University of Southern California To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
