Subject: [PATCH 2.6.22] [3/5] x86_64: Change PMDS invocation to single macro
Date: Wed, 15 Aug 2007 12:38:56 +0200 (CEST) [thread overview]
Message-ID: <20070815103856.606DA14F28@wotan.suse.de> (raw)
In-Reply-To: <200708151238.148026000@suse.de>
Very old binutils (2.12.90...) seem to have trouble with newlines
in assembler macro invocation. They put them into the resulting
argument expansion. In this case this lead to a parse error because
a .rept expression ended up spread over multiple lines. Change the PMDS()
invocation to a single line.
