> jne only takes 8bit displacement.
There are two opcodes for jne - 0x75 taking 8bit displacement, and 0x0f 0x85
taking 16/32bit displacement:
(pasted from IA-32 Intel Architecture Software Developer’s Manual Volume 2:
Instruction Set Reference)
75 cb
JNE rel8
Jump short if not equal (ZF=0)
0F 85 cw/cd
JNE rel16/32
Jump near if not equal (ZF=0)
Jcc is no different from JMP, both can take 8/(16/)32bit displacement - even in
64bit mode.
