re PR middle-end/70680 (OpenMP SIMD linear variable privatized too eagerly) 

[gcc]
2016-04-12  Michael Meissner  <meissner@linux.vnet.ibm.com>

	PR target/70680
	* config/rs6000/rs6000.md (ieee_128bit_vsx_neg<mode>2_internal):
	Do not use "=" constraint on an input constraint.
	(ieee_128bit_vsx_abs<mode>2_internal): Likewise.
	(ieee_128bit_vsx_nabs<mode>2_internal): Likewise.
	(ieee_128bit_vsx_nabs<mode>2): Correct splitter so that it
	generates (neg (abs ...)) instead of (abs ...).

[gcc/testsuite]
