Subject: [PATCH 4/4] trace-cmd: Support '+' opcode in print format
Date: Fri, 15 Jul 2011 20:00:41 -0700	[thread overview]
Message-ID: <1310785241-3799-4-git-send-email-vnagarnaik@google.com> (raw)
In-Reply-To: <1310785241-3799-1-git-send-email-vnagarnaik@google.com>

The '+' opcode is not supported in the arguments for the print format.
This patch adds support for it.
