Exactly what kind of damage are you talking about? Don't you think if there was a real problem with -O3, gentoo devs would have excluded it as an option, especially when they have an easy to apply mechanism for doing that (I have in mind the "filter-flags" && "replace-flags" functions in the ebuilds)? All of my gentoo systems were build using -O3 and I haven't met a single problem with this setting. Of course there are packages (like the already mentioned OO2 and some others) which won't build with extreme optimization and the devs have taken care of this by forcing appropriate C(XX)FLAGS. It is my opinion that the statements like "-O3 is wrong and can do damage" is nothing but FUD. It is questionable if "-O3" helps building faster packages than those built with "-O2" but for sure it won't do damage. -- Best regards, Daniel -- gentoo-user@gentoo.org mailing list
