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 ...).
