Right now we have mmx, 3dnow, 3dnowex, sse, sse2 and so on useflags present in the tree, almost never used to get new dependencies, but usually used to supply econf switches.
Hoping the S/N ratio here hasn't gotten too high... IMO the main purpose of USE flags should be econf switches. Pulling in dependancies should be viewed as more of a side-effect, even if a common one. If the user wants "./configure ... --enable-gtk", then they need gtk on their box. Similarly, the mmx,sse,3dnow,etc useflags should be there for econf switches, not additions to CFLAGS. If the autoconf script has an --enable-mmx option, then the proper way to control that is through a useflag. I don't object to ebuilds adding CFLAGS/CXXFLAGS based on the result of your has_cpuset (for example, --fpmath= could be useful), but I don't believe has_cpuset should be used to set econf switches. And users should absolutely not have to muck with bashrc to disable this. Add a FEATURE, or something, to enable/disable it if necessary. -Richard -- gentoo-dev@gentoo.org mailing list
