2899 (memref_referenced_p): Likewise.
2900 * loop.c (NUM_STORES): Increase to 30.
2901 (prescan_loop): Only non-constant calls set unknown_address_altered.
2902 (invariant_p): Add new arguments to true_dependence.
2903 (record_giv): Initialize unrolled and shared fields.
2904 (emit_iv_add_mult): Call record_base_value as needed.
2905 * loop.h (struct induction): Add unrolled and shared fields.
2906 * unroll.c (unroll_loop): Call record_base_value as needed.
2907 (copy_loop_body): Likewise.
2908 (final_biv_value): Likewise.
2909 (final_giv_value): Likewise.
2910 (find_splittable_regs): Likewise. Only create one new pseudo
2911 if we have multiple address GIVs that were combined with the same
2912 dst_reg GIV. Note when a new register is created due to unrolling.
2913 * rtl.c (reg_note_name): Add REG_NOALIAS.
2914 * rtl.h (enum reg_note): Similarly.
2915 (rtx_varies_p, may_trap_p, side_effects_p): Declare.
2916 (volatile_refs_p, volatile_insn_p, remove_note): Likewise.
2917 (note_stores, refers_to_regno_p, reg_overlap_mentioned_p): Likewise.
2918 (true_dependence, read_dependence, anti_dependence): Likewise.
2919 (output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
2920 (mark_user_reg, mark_reg_pointer): Likewise.
2923 * Integrate reload bugfix from Wilon which enables the PA port
2925 * reload1.c (reload): Sum needs for both OPADDR_ADDR and and
2926 OPERAND_ADDRESS when computing how many registers an insn needs.
2927 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
2929 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
2931 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
2932 in reload_reg_use_in_op_addr do not reach the end.
2933 do not reach the end.
2934 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
2935 RELOAD_FOR_OPERAND_ADDRESS.
