Probably because the GNU utils are written with support for each and every architecture and format in this world in mind.<p>lld however supports only x86_64, according to the blogpost. It&#x27;s got to be fast if the cruft is cut.<p>What are the most dominant archs in actual usage today anyways? I&#x27;d guess x86(_64), armv6&#x2F;v7&#x2F;64, MIPS for cheap&#x2F;crap routers and some SPARC... and ELF as the dominant binary format on *nix and PE&#x2F;COFF on win32&#x2F;64&#x2F;arm.
