Shared abi names are bad idea. For example mips abis : o32 n32 n64 eabi x86: x86_32 x86_x32 x86_64 Actualy first three one are equivalent in their internal behavior. But i dont think that its good idea to have one name for all. Think about multiarch installs where you can have binaries from different architectures in one system. -- Best Regards, Alexey 'Alexxy' Shvetsov Petersburg Nuclear Physics Institute, NRC Kurchatov Institute, Gatchina, Russia Department of Molecular and Radiation Biophysics Gentoo Team Ru Gentoo Linux Dev mailto:alexx...@gmail.com mailto:ale...@gentoo.org mailto:ale...@omrb.pnpi.spb.ru
