	* pa-protos.h (indexed_memory_operand, borx_reg_operand,
	move_dest_operand, move_src_operand): New protypes.
	(basereg_operand, move_operand, reg_or_nonsymb_mem_operand): Deleted.
	* pa.c (copy_reg_pointer, indexed_memory_operand, move_dest_operand,
	move_src_operand): New functions.
	(basereg_operand, reg_or_nonsymb_mem_operand, move_operand): Delete.
	(reg_or_0_or_nonsymb_mem_operand): Return false for unscaled indexed
	address until cse is not expected on targets with non-equivalent
	space registers.
	(hppa_legitimize_address): Canonicalize unscaled indexed addresses
	on targets non-equivalent space registers.
	(emit_move_sequence): Break out indexed addresses from destination
	operand.  Similarly, break out unscaled indexed addresses from
	source operand on targets with non-equivalent space registers.  Fix
	REG_POINTER flag when possible.  Mark register pointer when creating
	new pointers.
	(print_operand): Handle unscaled index addresses.
	* pa.h (IS_INDEX_ADDR_P, IS_LO_SUM_DLT_ADDR_P): New macro subroutines
	for EXTRA_CONSTRAINT.
	(EXTRA_CONSTRAINT): Rework to make more readable.
	(MODE_OK_FOR_SCALED_INDEXING_P, MODE_OK_FOR_UNSCALED_INDEXING_P): New
	subroutines for GO_IF_LEGITIMATE_ADDRESS.
	(GO_IF_LEGITIMATE_ADDRESS): Rework using new subroutines.  Allow scaled
	and unscaled addresses.  Canonicalize unscaled indexed addresses on
	targets with non-equivalent space registers.  Document issues in
	handling indexed address modes on PA-RISC.
	(PREDICATE_CODES): Update for new and deleted predicates.
	* pa.md (move_dest_operand, move_src_operand, indexed_memory_operand):
	Use new predicates in move patterns.
	Add peephole2 patterns to optimize floating point stores.  Fix
	constrain preferencing in move patterns.  Delete patterns for handling
	unscaled indexed memory loads.  Add missing load and store with
	base-register modification patterns.  Correct SFmode floating point
	store pattern.  Add missing zero extension loads.
