r242679 - in /trunk/gcc: ChangeLog config/rs600...

	* config/rs6000/rs6000.md (movdi_internal32): Change constraints
	so that DImode can be allocated to FP/vector registers in more
	cases, and we can avoid direct move operations.  If the register
	needs reloading, prefer GPRs over FP/vector registers.  In the
	case of FPR vs. Altivec registers, prefer FPR registers unless we
	have the ISA 3.0 reg+offset scalar instructions.
	(movdi_internal64): Likewise.

[gcc/testsuite]
2016-11-21  Michael Meissner  <meissner@linux.vnet.ibm.com>

	* gcc.target/powerpc/ppc-round2.c: Allow XSCVDPSXWS and XSCVDPUXWS
	to be generated instead of FCTIWUZ or FCTIWZ.
