Subject: [PATCH v11 1/6] gcc-plugins: Clean up the cgraph_create_edge* macros
Date: Fri,  6 Apr 2018 17:22:21 +0300	[thread overview]
Message-ID: <1523024546-6150-2-git-send-email-alex.popov@linux.com> (raw)
In-Reply-To: <1523024546-6150-1-git-send-email-alex.popov@linux.com>

Drop useless redefinitions of cgraph_create_edge* macros. Drop the unused
nest argument. Also support gcc-8, which doesn't have freq argument.

Signed-off-by: Alexander Popov <alex.popov@linux.com>
