10147 (invalidate_for_call): Remove memory elements from the hash table.
10148 (refers_to_mem_p, cse_rtx_addr_varies_p): Deleted.
10149 (cse_rtx_varies_p): New function. Derived from old
10150 cse_rtx_addr_varies_p.
10151 (cse_insn): Remove WRITES_MEMORY and INIT variables and all references.
10152 Don't call note_mem_written anymore. Stack pushes invalidate the stack
10153 pointer if PUSH_ROUNDING is defined. No longer need to call
10154 cse_rtx_addr_varies_p to decide if a MEM should be invalidated.
10155 (skipped_writes_memory): Remove variable.
10156 (invalidate_skipped_set): Simplify and wewrite to use invalidate_memory.
10157 (invalidate_skipped_block): Simplify for new alias analysis code.
10158 (cse_set_around_loop): Likewise.
10159 (cse_main): Call init_alias_analysis.
10160 * flags.h (flag_alias_check, flag_argument_noalias): Declare.
10161 * toplev.c (flag_alias_check, flag_argument_noalias): Define.
10162 (f_options): Add new alias checking arguments.
10163 (main): Set flag_alias_check when optimizing.
10164 * local_alloc (validate_equiv_mem_from_store): Add new arguments
10165 to true_dependence.
10166 (memref_referenced_p): Likewise.
10167 * loop.c (NUM_STORES): Increase to 30.
10168 (prescan_loop): Only non-constant calls set unknown_address_altered.
10169 (invariant_p): Add new arguments to true_dependence.
10170 (record_giv): Initialize unrolled and shared fields.
10171 (emit_iv_add_mult): Call record_base_value as needed.
10172 * loop.h (struct induction): Add unrolled and shared fields.
10173 * unroll.c (unroll_loop): Call record_base_value as needed.
10174 (copy_loop_body): Likewise.
10175 (final_biv_value): Likewise.
10176 (final_giv_value): Likewise.
10177 (find_splittable_regs): Likewise. Only create one new pseudo
10178 if we have multiple address GIVs that were combined with the same
10179 dst_reg GIV. Note when a new register is created due to unrolling.
10180 * rtl.c (reg_note_name): Add REG_NOALIAS.
10181 * rtl.h (enum reg_note): Similarly.
10182 (rtx_varies_p, may_trap_p, side_effects_p): Declare.
10183 (volatile_refs_p, volatile_insn_p, remove_note): Likewise.
10184 (note_stores, refers_to_regno_p, reg_overlap_mentioned_p): Likewise.
10185 (true_dependence, read_dependence, anti_dependence): Likewise.
10186 (output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
10187 (mark_user_reg, mark_reg_pointer): Likewise.
10190 * Integrate reload bugfix from Wilon which enables the PA port
10191 to bootstrap again.
10192 * reload1.c (reload): Sum needs for both OPADDR_ADDR and
10193 OPERAND_ADDRESS when computing how many registers an insn needs.
10194 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
10196 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
10197 OPADDR_ADDR reload.
10198 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
10199 in reload_reg_use_in_op_addr do not reach the end.
10200 do not reach the end.
10201 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
10202 RELOAD_FOR_OPERAND_ADDRESS.
