They did get rid of the delay slots and some other MIPS oddities

But legally distinct! I guess calling it Ｍ○ＰＳ was not enough for plausible deniability.

LoongArch is, on a first approximation, an almost RISC-V user space instruction set together with MIPS-like privileged instructions and registers.
