Please provide more information, such as the list of reload for the insn. There could be a number of reasons for a reload failure, some more obvious than others. The least obvious one I've come across (just a few days ago) is an unfortunate specification of CLASS_MAX_NREGS(), causing reloads to be sorted in the wrong order (see reload_reg_class_lower() in reload.c), thereby exhausting a small register class. > Can i disable filling/spilling for this register class? -ffixed-name_of_register -- Rask Ingemann Lambertsen
