Subject: [PATCH] Disable modpost warnings for linkonce sections
Date: Thu, 8 May 2008 13:41:11 +0200 [thread overview]
Message-ID: <20080508114111.GA20671@basil.nowhere.org> (raw)
Disable modpost warnings for linkonce sections
My build gives lots of warnings like
WARNING: sound/core/snd.o (.gnu.linkonce.wi.mpspec_def.h.30779716): unexpected section name.
The (.[number]+) following section name are ld generated and not expected.
Did you forget to use "ax"/"aw" in a .S file?
Note that for example <linux/init.h> contains
section definitions for use in .S files.
But for .linkonce. duplicated sections are actually ok and expected.
So just disable the warning for this case.
