Has anyone done a study of -Os vs -O2 with gcc-4.3.x,
Just a quick note while on the subject : -Os is known to break some packages.
Although it has been a while since I've last had a full -Os system, there was a time when -Os was a _very_bad_idea_. That's why the Gnome Herd (and upstream Gnome) won't support anything more than -O2.
Of course, if anyone wants to use -Os to actually fix bugs... :) Cheers Rémi -- gentoo-dev@lists.gentoo.org mailing list
