Subject: [PATCH] PR 66474, Document using %x<n> for VSX registers on PowerPC
Authentication-results: sourceware.org; auth=none

A user pointed out that we never documented the requirement to use %x<n> in the
ouptut template when VSX registers are used.  This patch adds the necessary
documentation. Is it ok to install in the trunk and the open release branches?

2015-06-09  Michael Meissner  <meissner@linux.vnet.ibm.com>

	PR target/66474
	* doc/md.texi (Machine Constraints): Document that on the PowerPC
	if you use a constraint that targets a VSX register, you must use
	%x<n> in the template.
