Subject: [PATCH v3 4/7] perf annotate: More exactly grep -v in symbol__disassemble()
Date: Fri, 10 Mar 2017 02:35:38 +0900	[thread overview]
Message-ID: <1489080941-3965-5-git-send-email-treeze.taeung@gmail.com> (raw)
In-Reply-To: <1489080941-3965-1-git-send-email-treeze.taeung@gmail.com>

To remove the first line containing file name and file format as below,

    $ objdump -l -d -S -C /home/taeung/a.out | head -2

    /home/taeung/a.out:     file format elf64-x86-64

currently perf-annotate use objdump with grep -v "file name".
But it cause a side effect eliminating filename:linenr of
output of 'objdump -l' so fix it.
