--- Comment #17 from Bill Schmidt <wschmidt at gcc dot gnu.org> --- Author: wschmidt Date: Thu Apr 23 00:21:39 2015 New Revision: 222349 URL: https://gcc.gnu.org/viewcvs?rev=222349&root=gcc&view=rev Log: [gcc] 2015-04-22 Bill Schmidt <wschm...@linux.vnet.ibm.com> PR target/65456 * config/rs6000/rs6000.c (rs6000_option_override_internal): For VSX + POWER8, enable TARGET_ALLOW_MOVMISALIGN and TARGET_EFFICIENT_UNALIGNED_VSX if not selected by command line option. (rs6000_builtin_mask_for_load): Return 0 for targets with efficient unaligned VSX accesses so that the vectorizer will use direct unaligned loads. (rs6000_builtin_support_vector_misalignment): Always return true for targets with efficient unaligned VSX accesses. (rs6000_builtin_vectorization_cost): Cost of unaligned loads and stores on targets with efficient unaligned VSX accesses is almost always the same as the cost of an aligned load or store, so model it that way. * config/rs6000/rs6000.h (SLOW_UNALIGNED_ACCESS): Return 0 for unaligned vectors if we have efficient unaligned VSX accesses. * config/rs6000/rs6000.opt (mefficient-unaligned-vector): New undocumented option.
