re PR target/65456 (powerpc64le autovectorized copy loop missed optimization)

[gcc]

2015-04-22  Bill Schmidt  <wschmidt@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.
