It uses the standard mechanism to avoid it, which is marking uses of FP registers for integer moves, loads and stores with "*". This tells the register allocator to ignore those alternatives. AFAIK it is effective and I think any cases where it doesn't work would be fair bug reports. It becomes a lot more difficult to define with things like the Loongson extensions though, since some of those are also useful as scalar integer operations. And of course the same goes for MSA.
