大家好,请教一个问题。我在使用IDA逆向一个android工程时发现有函数被提示:unused,请问unused代表什么意思啊?
该函数在IDA里如下:
CODE:001B73F4 .byte 7
CODE:001B73F5 .byte 0
CODE:001B73F6 .byte 1
CODE:001B73F7 .byte 0
CODE:001B73F8 .byte 2
CODE:001B73F9 .byte 0
CODE:001B73FA .byte 2
CODE:001B73FB .byte 0
CODE:001B73FC .byte 0x75 # u
CODE:001B73FD .byte 0x65 # e
CODE:001B73FE .byte 0x64 # d
CODE:001B73FF .byte 0
CODE:001B7400 .byte 0x2A # *
CODE:001B7401 .byte 0
CODE:001B7402 .byte 0
CODE:001B7403 .byte 0
CODE:001B7404 Method 7 (0x7):
CODE:001B7404 public java.lang.String
CODE:001B7404 a.a.a.bc()
CODE:001B7404 this = v6
CODE:001B7404
UNUSED
CODE:001B7406 const/16 v1, 0x20
CODE:001B740A new-array v0, v1, <t: char[]>
CODE:001B740E if-eqz v1, locret
CODE:001B7412 # try 0x1B7412-0x1B741E:
CODE:001B7412 const-string v0, empty_str
CODE:001B7416 nop
