5277 (schedule_insns): Always call init_alias_analysis.
5278 * calls.c (expand_call): Note calls to malloc, calloc, and realloc;
5279 mark return value from such functions as a pointer and keep track of
5280 them for alias analysis. If a return value from a function is a
5281 pointer, mark it as such.
5282 * combine.c (distribute_notes): Handle REG_NOALIAS.
5283 * cse.c (struct write_data): Delete. No longer needed.
5284 (invalidate): Don't call set_nonvarying_address_components anymore.
5285 Use true_dependence to decide if an entry should be removed from
5287 (invalidate_memory): Remove WRITES argument, simplify appropriately.
5289 (note_mem_written): Similarly for WRITE_PTR argument.
5290 (invalidate_from_clobbers): Similarly for W argument.
5291 (invalidate_for_call): Remove memory elements from the hash table.
5292 (refers_to_mem_p, cse_rtx_addr_varies_p): Deleted.
5293 (cse_rtx_varies_p): New function. Derived from old
5294 cse_rtx_addr_varies_p.
5295 (cse_insn): Remove WRITES_MEMORY and INIT variables and all references.
5296 Don't call note_mem_written anymore. Stack pushes invalidate the stack
5297 pointer if PUSH_ROUNDING is defined. No longer need to call
5298 cse_rtx_addr_varies_p to decide if a MEM should be invalidated.
5299 (skipped_writes_memory): Remove variable.
5300 (invalidate_skipped_set): Simplify and wewrite to use invalidate_memory.
5301 (invalidate_skipped_block): Simplify for new alias analysis code.
5302 (cse_set_around_loop): Likewise.
5303 (cse_main): Call init_alias_analysis.
5304 * flags.h (flag_alias_check, flag_argument_noalias): Declare.
5305 * toplev.c (flag_alias_check, flag_argument_noalias): Define.
5306 (f_options): Add new alias checking arguments.
5307 (main): Set flag_alias_check when optimizing.
5308 * local_alloc (validate_equiv_mem_from_store): Add new arguments
5310 (memref_referenced_p): Likewise.
5311 * loop.c (NUM_STORES): Increase to 30.
5312 (prescan_loop): Only non-constant calls set unknown_address_altered.
5313 (invariant_p): Add new arguments to true_dependence.
5314 (record_giv): Initialize unrolled and shared fields.
5315 (emit_iv_add_mult): Call record_base_value as needed.
5316 * loop.h (struct induction): Add unrolled and shared fields.
5317 * unroll.c (unroll_loop): Call record_base_value as needed.
5318 (copy_loop_body): Likewise.
5319 (final_biv_value): Likewise.
5320 (final_giv_value): Likewise.
5321 (find_splittable_regs): Likewise. Only create one new pseudo
5322 if we have multiple address GIVs that were combined with the same
5323 dst_reg GIV. Note when a new register is created due to unrolling.
5324 * rtl.c (reg_note_name): Add REG_NOALIAS.
5325 * rtl.h (enum reg_note): Similarly.
5326 (rtx_varies_p, may_trap_p, side_effects_p): Declare.
5327 (volatile_refs_p, volatile_insn_p, remove_note): Likewise.
5328 (note_stores, refers_to_regno_p, reg_overlap_mentioned_p): Likewise.
5329 (true_dependence, read_dependence, anti_dependence): Likewise.
5330 (output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
5331 (mark_user_reg, mark_reg_pointer): Likewise.
5334 * Integrate reload bugfix from Wilon which enables the PA port
5336 * reload1.c (reload): Sum needs for both OPADDR_ADDR and and
5337 OPERAND_ADDRESS when computing how many registers an insn needs.
5338 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
5340 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
5342 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
5343 in reload_reg_use_in_op_addr do not reach the end.
5344 do not reach the end.
5345 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
5346 RELOAD_FOR_OPERAND_ADDRESS.
