	Back port mainline subversion id 209025.
	2014-04-02  Michael Meissner  <meissner@linux.vnet.ibm.com>

	PR target/60735
	* config/rs6000/rs6000.c (rs6000_hard_regno_mode_ok): If we have
	software floating point or no floating point registers, do not
	allow any type in the FPRs.  Eliminate a test for SPE SIMD types
	in GPRs that occurs after we tested for GPRs that would never be
	true.

	* config/rs6000/rs6000.md (mov<mode>_softfloat32, FMOVE64):
	Rewrite tests to use TARGET_DOUBLE_FLOAT and TARGET_E500_DOUBLE,
	since the FMOVE64 type is DFmode/DDmode.  If TARGET_E500_DOUBLE,
	specifically allow DDmode, since that does not use the SPE SIMD
	instructions.
