MIPS II did introduce ll/sc in 1991 and it was becoming widely available with MIPS III and some pseudo- MIPS II R3000 variants also in the embedded markets and MIPS32/MIPS64 were based on that. So ll/sc-less processors are a very small part of the market of Linux/MIPS these days, not really worth to optimize for. Ralf
