re PR target/60735 (GCC targeting E500 with SPE has errors with the _Decimal64 type)

[gcc]
2014-04-21  Michael Meissner  <meissner@linux.vnet.ibm.com>

	PR target/60735
	* config/rs6000/rs6000.md (mov<mode>_softfloat32, FMOVE64 case):
	If mode is DDmode and TARGET_E500_DOUBLE allow move.

	* config/rs6000/rs6000.c (rs6000_debug_reg_global): Print some
	more debug information for E500 if -mdebug=reg.

[gcc/testsuite]
2014-04-21  Michael Meissner  <meissner@linux.vnet.ibm.com>

	PR target/60735
	* gcc.target/powerpc/pr60735.c: New test.  Insure _Decimal64 does
	not cause errors if -mspe.
