Subject: [uml-devel] [PATCH 4/6] UML - memcpy export needs to follow host declaration
Date: Tue, 3 Jun 2008 15:02:37 -0400 [thread overview]
Message-ID: <20080603190237.GA9517@c2.user-mode-linux.org> (raw)
x86_64 defines either memcpy or __memcpy depending on the gcc version,
and it looks like UML needs to follow that in its exporting.
