* gas/arm/copro.d, gas/arm/fp-save.d, gas/arm/float.d, gas/arm/fpa-mem.d: Update for removed generic coprocessor instructions and expanded PC-relative offsets. opcodes/ * arm-dis.c (coprocessor_opcodes): Use %A instead of %C. Remove generic coprocessor instructions for FPA loads and stores. (print_insn_coprocessor): Remove %C support. Display address for PC-relative offsets in %A.
