2014-02-19  Bill Schmidt  <wschmidt@linux.vnet.ibm.com>

	Backport from mainline r207919.
	2014-02-19  Bill Schmidt  <wschmidt@linux.vnet.ibm.com>

	2014-02-18  Michael Meissner  <meissner@linux.vnet.ibm.com>

	PR target/60203
	* config/rs6000/rs6000.md (mov<mode>_64bit, TF/TDmode moves):
	Split 64-bit moves into 2 patterns.  Do not allow the use of
	direct move for TDmode in little endian, since the decimal value

	ordered in a big endian fashion, and normal subreg's of TDmode are
	not allowed.
