I'll note that we need to add support for the iwMMXt registers but the attached patch (untested) should be what is needed to support the iwMMxt registers and this should be something that should be incorporated into your ARM RTL epilogues patch as well. My understanding is that this is all you should need to do as there is a wldrd as a part of *iwmmx*_movdi instruction and therefore this should just work in this form. Xinyu can you help in testing this patch once this is applied along with your other patches to turn on Thumb2 for iwmmxt ? cheers Ramana
