IDA反编译ARM静态链接程序

IDA在反编译ARM的静态链接程序时，是没有输入符号表的，系统调用均采用SVC形式。如：

.text:0000B380 ; =============== S U B R O U T I N E =======================================.text:0000B380.text:0000B380.text:0000B380 sub_B380                                ; CODE XREF: sub_8BB8+12p.text:0000B380 STMFD   SP!, {R4,R7}.text:0000B384 MOV     R7, #0x2A.text:0000B388 SVC     0.text:0000B38C LDMFD   SP!, {R4,R7}.text:0000B390 MOVS    R0, R0.text:0000B394 BXPL    LR.text:0000B398 B       sub_168DC.text:0000B398 ; End of function sub_B380.text:0000B398.text:0000B398 ; ---------------------------------------------------------------------------

此时需要根据Andorid源码对应平台的unistd.h,来识别相应的系统调用.根据自己修改后，反汇编代码如下：

.text:0000B380 ; =============== S U B R O U T I N E =======================================.text:0000B380.text:0000B380.text:0000B380 pipe                                    ; CODE XREF: sub_8BB8+12p.text:0000B380 STMFD   SP!, {R4,R7}.text:0000B384 MOV     R7, #0x2A.text:0000B388 SVC     0.text:0000B38C LDMFD   SP!, {R4,R7}.text:0000B390 MOVS    R0, R0.text:0000B394 BXPL    LR.text:0000B398 B       __set_errno.text:0000B398 ; End of function pipe.text:0000B398.text:0000B398 ; ---------------------------------------------------------------------------
