Yes this is case which looks like

    unsigned short cw;
    __asm__ __volatile__("fstcw %0" : "=m"(cw));
    cw &= ~(0x01|0x04|0x08);
    __asm__ __volatile__("fldcw %0" : : "m"(cw));
res = a*b;
    __asm__ __volatile__("fwait" : "=m"(erl_fp_exception) : "m"(f));

----
res = a*b can be moved anywhere.
