2.11 GDB中以Intel风格反汇编
Q: GDB反汇编时默认是AT&T风格，我不习惯。
A:
(gdb) set disassembly-flavor att // AT&T风格，这是默认值
(gdb) x/4i $pc
0xb7ef48d0 sendmsg: cmpl $0x0,%gs:0xc
0xb7ef48d8 sendmsg+8: jne 0xb7ef48f9
0xb7ef48da sendmsg+10: mov %ebx,%edx
0xb7ef48dc sendmsg+12: mov $0x66,%eax
(gdb) set disassembly-flavor intel // Intel风格
(gdb) x/4i $pc
0xb7ef48d0 sendmsg: cmp DWORD PTR gs:0xc,0x0
0xb7ef48d8 sendmsg+8: jne 0xb7ef48f9
0xb7ef48da sendmsg+10: mov edx,ebx
0xb7ef48dc sendmsg+12: mov eax,0x66
