You can do both.
Ooooh, sorry, yeah. That's true. Although, rather than saying "don't use -O3" to the user, I think it's better just to replace -O3 with -O2 in the ebuild until upstream fixes things. I just don't think the user should ever feel breakage is their "fault" because they used advertised features of their compiler and headed the associated warnings. Now, I have to problem with developers closing some bug opened by a ricer out there that's added -ffast-math to their CFLAGS as WONTFIX/INVALID since it's not really a problem. All the parts provided by Gentoo (ebuild, source, compiler, portage, etc.) all behaving properly. It's just that, just like the warning says, programs WILL break under -ffast-math. > Indeed, there aren’t many fields of ‘production’ in which end users > ought to be encouraged to try things that expose flaws in design or > manufacture. I disagree. I want to know about those flaws, and I want the manufactures to fix them -- which is why I like Consumer Reports so much. :) I encourage people to test the tensile strength of their Windows CDs and let me know at what point they break. I'll collect and publish statistics. ;) -- "If there's one thing we've established over the years, it's that the vast majority of our users don't have the slightest clue what's best for them in terms of package stability." -- Gentoo Developer Ciaran McCreesh
