Do people really want to be notified if a package gains support for a new instruction set? I know I don’t. I would rather have all possible instruction set extensions available as flags and set whichever ones my CPU has once, at install time. If a package gains support for an extension later, then whenever it upgrades, it will just work, because the relevant flag will already be set in make.conf from back when I installed Gentoo on the box. For this to work right requires that a dev add all the extensions to the flag before I buy the CPU. All that requires is knowing the names, though; it would be fine if no package actually uses the feature yet. -- Christopher Head
