7221 Don't call note_mem_written anymore. Stack pushes invalidate the stack
7222 pointer if PUSH_ROUNDING is defined. No longer need to call
7223 cse_rtx_addr_varies_p to decide if a MEM should be invalidated.
7224 (skipped_writes_memory): Remove variable.
7225 (invalidate_skipped_set): Simplify and wewrite to use invalidate_memory.
7226 (invalidate_skipped_block): Simplify for new alias analysis code.
7227 (cse_set_around_loop): Likewise.
7228 (cse_main): Call init_alias_analysis.
7229 * flags.h (flag_alias_check, flag_argument_noalias): Declare.
7230 * toplev.c (flag_alias_check, flag_argument_noalias): Define.
7231 (f_options): Add new alias checking arguments.
7232 (main): Set flag_alias_check when optimizing.
7233 * local_alloc (validate_equiv_mem_from_store): Add new arguments
7235 (memref_referenced_p): Likewise.
7236 * loop.c (NUM_STORES): Increase to 30.
7237 (prescan_loop): Only non-constant calls set unknown_address_altered.
7238 (invariant_p): Add new arguments to true_dependence.
7239 (record_giv): Initialize unrolled and shared fields.
7240 (emit_iv_add_mult): Call record_base_value as needed.
7241 * loop.h (struct induction): Add unrolled and shared fields.
7242 * unroll.c (unroll_loop): Call record_base_value as needed.
7243 (copy_loop_body): Likewise.
7244 (final_biv_value): Likewise.
7245 (final_giv_value): Likewise.
7246 (find_splittable_regs): Likewise. Only create one new pseudo
7247 if we have multiple address GIVs that were combined with the same
7248 dst_reg GIV. Note when a new register is created due to unrolling.
7249 * rtl.c (reg_note_name): Add REG_NOALIAS.
7250 * rtl.h (enum reg_note): Similarly.
7251 (rtx_varies_p, may_trap_p, side_effects_p): Declare.
7252 (volatile_refs_p, volatile_insn_p, remove_note): Likewise.
7253 (note_stores, refers_to_regno_p, reg_overlap_mentioned_p): Likewise.
7254 (true_dependence, read_dependence, anti_dependence): Likewise.
7255 (output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
7256 (mark_user_reg, mark_reg_pointer): Likewise.
7259 * Integrate reload bugfix from Wilon which enables the PA port
7261 * reload1.c (reload): Sum needs for both OPADDR_ADDR and and
7262 OPERAND_ADDRESS when computing how many registers an insn needs.
7263 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
7265 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
7267 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
7268 in reload_reg_use_in_op_addr do not reach the end.
7269 do not reach the end.
7270 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
7271 RELOAD_FOR_OPERAND_ADDRESS.
