Subject: [RFC][PATCH v4 24/32] objtool: mcount: Reduce usage of _size wrapper
Date: Tue, 2 Jun 2020 12:50:17 -0700 [thread overview]
Message-ID: <a420cea8b31cb3e9a611f251090da64799bb0360.1591125127.git.mhelsley@vmware.com> (raw)
In-Reply-To: <cover.1591125127.git.mhelsley@vmware.com>
Use a new loc_size parameter to append_func() rather than
use the wrapper's _size macro directly.
Signed-off-by: Matt Helsley <mhelsley@vmware.com>
