pa.md (abssi2): New pattern.

	* pa.md (abssi2): New pattern.

	* pa.c (secondary_reload_class): Loads from reg+d addresses into
	FP registers don't need secondary reloads.
	* pa.h: Delete soem #if 0 code.  Update some comments.
	(EXTRA_CONSTRAINT, case 'Q'): Only accept valid memory addresses.

        * pa.h (RTX_COSTS): Tege's rewrite.

	* pa.c (hppa_legitimize_address): Generate unscaled indexed
	addressing for (plus (symbol_ref) (reg)).
	(emit_move_sequence): Set REGNO_POINTER_FLAG appropriately
	to encourage unscaled indexing modes.
	(basereg_operand): New function for unscaled index address support.
	* pa.md (unscaled indexing patterns): New patterns for unscaled
	index address support.

	* pa.h (MOVE_RATIO): Define.
	* pa.md (movstrsi expander): Refine tests for when to use the
	library routine instead of an inlined loop copy.  Provide an
	additional scratch register for use in the inlined loop copy.
	(movstrsi_internal): Name the pattern for ease of use.  Add
	additional scratch register.
	* pa.c (output_block_move): Greatly simplify.  Use 2X unrolled
	copy loops to improve performance.
	(compute_movstrsi_length): Corresponding changes.

	* pa.c (print_operand): Handle 'y' case for reversed FP
	comparisons.  Delete some #if 0 code.  Fix various comment typos.
	* pa.md (fcmp patterns): Try and reverse the comparison to avoid
	useless add,tr insns.
