It shows that there are some fundamental issues with move patterns like `movsi_ie`. It seems real-world code is very easy to hit that problem. I'm thinking to remove the FP alternatives from 'movsi_ie' and similarly, remove the GP alternatives from 'movsf_ie'. Kaz, since you've been looking= in similar places recently ( e.g. https://github.com/kazkojima/gcc/commit/ed9236ca72bda40f4f68ce6ff0cea7a47d7= 10836 ), what's your opinion on that?=
