MicroBlaze: Widen mask used in opcodes/microblaze-dis,c
Instead of using 0xFFFF0000, or with (~0xFFFF) to sign extend
negative 16-bit value and with (~0xFFFF) to extract higher order
address bits
opcodes/
* microblaze-dis.c: (print_insn_microblaze): Widen mask
(microblaze_get_target_address): Likewis
