Confirmed. X86.rb that picks X86 instructions uses SSE2 instructions in various places. You appear to hit mulsd in this case, but there are a few other examples of SSE2 instructions.

I will see if this can be fixed, but I am afraid there will be resistance to implementing it the right way since there is a fallback called cloop. Unfortunately cloop is not that fast and also has a lot of bugs since it is only used for otherwise unsupported architectures.
