[gcc]
2017-08-24  Michael Meissner  <meissner@linux.vnet.ibm.com>

	* config/rs6000/rs6000.opt (-mpower9-dform-scalar): Delete
	undocumented switches.
	(-mpower9-dform-vector): Likewise.
	(-mpower9-dform): Likewise.
	* config/rs6000/rs6000-c.c (rs6000_target_modify_macros): Update
	comments to delete references to -mpower9-dform* switches.
	* config/rs6000/predicates.md (vsx_quad_dform_memory_operand):
	Delete reference to -mpower9-dform* switches, test for
	-mpower9-vector instead.
	* config/rs6000/rs6000-cpus.def (ISA_3_0_MASKS_SERVER): Likewise.
	(OTHER_P9_VECTOR_MASKS): Likewise.
	(POWERPC_MASKS): Likewise.
	* config/rs6000/rs6000.c (rs6000_setup_reg_addr_masks): Change
	tests against -mpower9-dform* to -mpower9-vector.  Delete code
	that checked for -mpower9-dform* consistancy with other options.
	Add test for -mpower9-misc to enable other power9 switches.
	(rs6000_init_hard_regno_mode_ok): Likewise.
	(rs6000_option_override_internal): Likewise.
	(rs6000_emit_prologue): Likewise.
	(rs6000_emit_epilogue): Likewise.
	(rs6000_opt_masks): Delete -mpower9-dform-{scalar,vector}.
	(rs6000_disable_incompatiable_switches): Delete -mpower9-dform.
	(emit_fusion_p9_load): Change tests for -mpower9-dform-scalar
	-mpower9-vector.
	(emit_fusion_p9_store): Likewise.
	* config/rs6000/rs6000.h (TARGET_P9_DFORM_SCALAR): Delete
	resetting these macros if the assembler does not support ISA 3.0
	instructions.
	(TARGET_P9_DFORM_VECTOR): Likewise.
	* config/rs6000/rs6000.md (peepholes to optimize altivec memory):
	Change to use -mpower9-vector instead of -mpower9-dform-scalar.
