Subject: [ARM] : Remove superfluous test in arm_function_arg
Date: Thu, 15 Jul 2010 10:35:15 -0000
From: John Tytgat <John.Tytgat@aaug.net>

Message-Id: <678f613751.Jo@hobbes.bass-software.com>
To: gcc-patches@gcc.gnu.org

Attached patch removes in arm_function_arg() a superfluous test on one
of its parameters as that test is already done at the beginning of the
routine and the parameter doesn't change during the function.

John Tytgat  <John.Tytgat@aaug.net>

	* config/arm/arm.c (arm_function_arg): Remove superfluous test.

Please commit after positive review.

John.
