What about add a interface to output the assembly codes follow inferior execution

Hi guys,

I am not sure gdb have a interface to output assembly codes except
"disassemble".
Maybe gdb can support a interface can output assembly codes of next
part of code.

For example:
#If exec-disassemble set to auto, just output assembly codes if there
is not line message.
#It will be the default value.
(gdb) set exec-disassemble auto
(gdb) si
0x080483ee	24		b = printf ("a = %d b = %d c = %d\n", a, b, c);
(gdb) si
0x080482d8 in printf@plt ()
Current language:  auto; currently asm
0x080482d8 <printf@plt+0>:	jmp    *0x8049670
(gdb) si
0x080482de in printf@plt ()
0x080482de <printf@plt+6>:	push   $0x10

#If exec-disassemble set to on, gdb will always output assembly codes.
(gdb) set exec-disassemble on
(gdb) n
26		printf ("a = %d b = %d c = %d\n", a, b, c);
 80483fe:	8b 15 84 96 04 08    	mov    0x8049684,%edx
 8048404:	8b 45 f4             	mov    -0xc(%ebp),%eax
 8048407:	89 44 24 0c          	mov    %eax,0xc(%esp)
 804840b:	8b 45 f8             	mov    -0x8(%ebp),%eax
 804840e:	89 44 24 08          	mov    %eax,0x8(%esp)
 8048412:	89 54 24 04          	mov    %edx,0x4(%esp)
 8048416:	c7 04 24 58 85 04 08 	movl   $0x8048558,(%esp)
 804841d:	e8 b6 fe ff ff       	call   80482d8 <printf@plt>

#If exec-disassemble set to off, gdb will work like before.
(gdb) set exec-disassemble off


What do you think about it?


Thanks,
