Subject: [PATCH 1/1] [IA64] Deletion of unnecessary checks before the function call "unw_remove_unwind_table"
Date: Fri, 21 Nov 2014 23:01:41 +0000 [thread overview]
Message-ID: <546FC455.8090702@users.sourceforge.net> (raw)
In-Reply-To: <5317A59D.4@users.sourceforge.net>
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Fri, 21 Nov 2014 23:57:28 +0100
The unw_remove_unwind_table() function performs also input parameter validation.
Thus the test around the call is not needed.
This issue was detected by using the Coccinelle software.
