Note that it's a bit more complicated. I couldn't use your `dup` trick, because I need to put the value into a GP reg and one half of it to a FP reg. The Panama code doesn't support that (IllegalArgumentException: Invalid operand type: interface java.lang.foreign.MemorySegment. float expected).

Thanks, your solution looks good.
