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 <sendmsg+41>
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 <sendmsg+41>
0xb7ef48da <sendmsg+10>:        mov    edx,ebx
0xb7ef48dc <sendmsg+12>:        mov    eax,0x66
