2.13 在GDB中x/4i时不想看到符号式偏移
Q:
(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
我不想要sendmsg+n这种显示。
A:
(gdb) set print max-symbolic-offset 0 // 缺省为0，表示unlimited
(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 print max-symbolic-offset 1
(gdb) x/4i $pc
0xb7ef48d0 sendmsg: cmpl $0x0,%gs:0xc
0xb7ef48d8: jne 0xb7ef48f9
0xb7ef48da: mov %ebx,%edx
0xb7ef48dc: mov $0x66,%eax
暂时没有找到办法彻底禁止符号式偏移出现。
