Ma= ybe > you can clarify? Thanks again. The Linux and ELF multilibs are different: for Linux we assumed ISA compatibility was up to the distro, so multilib just handles the ABI side of things. That said, C does bleed into the ABI so we should really fix that = -- presumably we'd need some psABI work there, compatibility is going to be a = bit clunky so it's probably best to just add two explicit ABI variants.=
