11179 (memref_referenced_p): Likewise.
11180 * loop.c (NUM_STORES): Increase to 30.
11181 (prescan_loop): Only non-constant calls set unknown_address_altered.
11182 (invariant_p): Add new arguments to true_dependence.
11183 (record_giv): Initialize unrolled and shared fields.
11184 (emit_iv_add_mult): Call record_base_value as needed.
11185 * loop.h (struct induction): Add unrolled and shared fields.
11186 * unroll.c (unroll_loop): Call record_base_value as needed.
11187 (copy_loop_body): Likewise.
11188 (final_biv_value): Likewise.
11189 (final_giv_value): Likewise.
11190 (find_splittable_regs): Likewise. Only create one new pseudo
11191 if we have multiple address GIVs that were combined with the same
11192 dst_reg GIV. Note when a new register is created due to unrolling.
11193 * rtl.c (reg_note_name): Add REG_NOALIAS.
11194 * rtl.h (enum reg_note): Similarly.
11195 (rtx_varies_p, may_trap_p, side_effects_p): Declare.
11196 (volatile_refs_p, volatile_insn_p, remove_note): Likewise.
11197 (note_stores, refers_to_regno_p, reg_overlap_mentioned_p): Likewise.
11198 (true_dependence, read_dependence, anti_dependence): Likewise.
11199 (output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
11200 (mark_user_reg, mark_reg_pointer): Likewise.
11203 * Integrate reload bugfix from Wilon which enables the PA port
11204 to bootstrap again.
11205 * reload1.c (reload): Sum needs for both OPADDR_ADDR and
11206 OPERAND_ADDRESS when computing how many registers an insn needs.
11207 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
11208 conflict.
11209 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
11210 OPADDR_ADDR reload.
11211 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
11212 in reload_reg_use_in_op_addr do not reach the end.
11213 do not reach the end.
11214 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
11215 RELOAD_FOR_OPERAND_ADDRESS.
