|
|
I changed my make.conf, make.conf.build and make.globals files to have the following.
CFLAGS="-march=duron -O3 -fomit-frame-pointer"
CXXFLAGS="${CFLAGS}"
I figured duron since after all, i have a duron 1200Mhz.
I noticed in the Makefile under /usr/src/linux its a whole different ballgame there.
Would i be safe to put those two lines up there in the Makefile and still assume safety?
Also, since i just discovered these two lines how is it possible to rebuild the ENTIRE system again with those ? cause frankly KDE is still a dog when it comes to speed.
Thanks |

Had to replace it with athlon-tbird.
Maybe they changed things. I tried it aobut 3 weeks ago or so...
Shouldn't see any different, duron = athlon-tbird for everything that really matters. Well, instruction set wise...

No. People will disagree with me, and say "I use -O9 -munroll-everything -mscramble-registers and there's no problem at all...rac's on crack!" You can choose to believe them. In my experience, the kernel has very good reasons for choosing its preferred compiler options, and you are better off respecting them.
