Subject: [PATCH 02/27] perf tests: Make objdump disassemble zero blocks
Date: Mon, 14 Sep 2015 13:38:05 -0300 [thread overview]
Message-ID: <1442248710-2339-3-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1442248710-2339-1-git-send-email-acme@kernel.org>
From: Jan Stancek <jstancek@redhat.com>
Add -z parameter to avoid skipping zero blocks:
ffffffff816704fe <sysret_check+0x4b>:
ffffffff816704fe: 7b 34 jnp ffffffff81670534 <sysret_signal+0x1c>
...
ffffffff81670501 <sysret_careful>:
ffffffff81670501: 0f ba e2 03 bt $0x3,%edx
ffffffff81670505: 73 11 jae ffffffff81670518 <sysret_signal>
