Hi Andre,

I've not looked at fast isel much before, but it looks like it is responsible for creating virtual registers of the correct register class for the instructions it's creating. If you grep for createResultReg in ARMFastISel.cpp, there are a few places where it has to select between GPRRegClass and rGPRRegClass, have you tried updating that code to use rGPR2RegClass when building a VMOVSR?
