Subject: How to show instructions in one record
Date: Tue, 06 Sep 2016 14:14:00 -0000	[thread overview]
Message-ID: <CAD-N9QV0vLTAmyo76HGZZYuToDZbOZzsrvDfmj535Wb8VWANvg@mail.gmail.com> (raw)

Dear all,

I encounter the following problem when I show instructions in one record,

(gdb) b main
Breakpoint 1 at 0x80483f3: file simple.c, line 7.
(gdb) r
Starting program: /home/vagrant/simple/simple

Breakpoint 1, main (argc=1, argv=0xbffff7a4) at simple.c:7
7    crash = buff;
(gdb) record
(gdb) c
Continuing.

Program received signal SIGSEGV, Segmentation fault.
0x08048420 in main (argc=1, argv=0xbffff7a4) at simple.c:10
10    for (p=buff,q=argv[1];(*q);p++,q++)
(gdb) record
btrace                 full                   goto
save
delete                 function-call-history  instruction-history
stop
(gdb) record instruction-history
You can't do that when your target is `record-full'

Then I try "record-core", the same result.
At last, I try "record-btrace", my system does not support branch tracing.
So how to show instructions in one record?

My best regards to you.
