Subject: [PATCH 1/7] check_types_equal: short circuit check if identical pointers are used
Date: Thu, 04 Feb 2016 17:29:00 -0000 [thread overview]
Message-ID: <1454606973-31017-2-git-send-email-jeffm@suse.com> (raw)
In-Reply-To: <1454606973-31017-1-git-send-email-jeffm@suse.com>
From: Jeff Mahoney <jeffm@suse.com>
If two types share identical pointers, we don't need to check typedefs
before comparing the result.
