By adjusting the rules as to what's legal GIMPLE, yes. This may require changes to several passes. > 3. Is there any other port which have complex arithmetic instructions? No. I seem to remember that there used to be one, but it was removed as unmaintained years ago. The closest that seems to exist at the moment are vector instructions that can be used to accelerate arithmetic over arrays of complex numbers. But for individual complex operations those instructions don't help much. r~
