At minimum target-arm/op.c, target-arm/translate.c, and target-arm/cpu.h.

Note that that FPA is implemented differently. I uses the same emulator as the 
linux kernel, hooked up to the undefined instruction interrupt. I wouldn't 
advise doing this as performance is really awful. It's approximately 2x 
slower than target soft-float, and I guess about 20x slower than a native 
implementation.
