	<patch #10>
	* config/rs6000/constraints.md (wb constraint): New constraint for
	ISA 3.0 d-form scalar addressing.

	* config/rs6000/rs6000.c (mode_supports_vmx_dform): Add support
	for ISA 3.0 D-form addressing to load SFmode/DFmode scalars into
	Altivec registers.  Add wb constraint for Altivec registers with
	D-form addressing.  If we have ISA 3.0 d-form support, undo
	secondary reload support for using FPR registers if we want to do
	D-form addressing.
	(rs6000_debug_reg_global): Likewise.
	(rs6000_setup_reg_addr_masks): Likewise.
	(rs6000_init_hard_regno_mode_ok): Likewise.
	(rs6000_secondary_reload): Likewise.
	(rs6000_preferred_reload_class): Likewise.
	(rs6000_secondary_reload_class): Likewise.

	* config/rs6000/rs6000.h (enum r6000_reg_class_enum): Add wb
	constraint.

	* config/rs6000/rs6000.md (f32_lr2 mode attribute): Add support
	for ISA 3.0 SFmode/DFmode d-form addressing to Altivec registers.
	(f32_lm2): Likewise.
	(f32_li2): Likewise.
	(f32_sr2): Likewise.
	(f32_sm2): Likewise.
	(f32_si2): Likewise.

	(mov<mode>_hardfloat64): Likewise.

	* doc/md.texi (RS/6000 constraints): Document wb constraint.
	Fixup we constraint documentation.
