* 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.
