--- Comment #7 from Tommy Murphy <tommy_murphy at hotmail dot com> --- (In reply to palmer from comment #3) > 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. FYI this issue has cropped up again here: * https://github.com/riscv-collab/riscv-gnu-toolchain/issues/1393
