895 * Integrate alias analysis changes from jfc@mit.edu
896 * Makefile.in (OBJS): Add alias.o
897 (alias.o): Add dependencies.
898 * alias.c: New file.
899 * sched.c: Remove alias analysis code. It lives in alias.c now.
900 (sched_analyze_2): Add new arguments to true_dependence.
901 (schedule_insns): Always call init_alias_analysis.
902 * calls.c (expand_call): Note calls to malloc, calloc, and realloc;
903 mark return value from such functions as a pointer and keep track of
904 them for alias analysis. If a return value from a function is a
905 pointer, mark it as such.
906 * combine.c (distribute_notes): Handle REG_NOALIAS.
907 * cse.c (struct write_data): Delete. No longer needed.
908 (invalidate): Don't call set_nonvarying_address_components anymore.
909 Use true_dependence to decide if an entry should be removed from
910 the hash table.
911 (invalidate_memory): Remove WRITES argument, simplify appropriately.
912 Fix all callers.
913 (note_mem_written): Similarly for WRITE_PTR argument.
914 (invalidate_from_clobbers): Similarly for W argument.
915 (invalidate_for_call): Remove memory elements from the hash table.
916 (refers_to_mem_p, cse_rtx_addr_varies_p): Deleted.
917 (cse_rtx_varies_p): New function. Derived from old
918 cse_rtx_addr_varies_p.
919 (cse_insn): Remove WRITES_MEMORY and INIT variables and all references.
920 Don't call note_mem_written anymore. Stack pushes invalidate the stack
921 pointer if PUSH_ROUNDING is defined. No longer need to call
922 cse_rtx_addr_varies_p to decide if a MEM should be invalidated.
923 (skipped_writes_memory): Remove variable.
924 (invalidate_skipped_set): Simplify and wewrite to use invalidate_memory.
925 (invalidate_skipped_block): Simplify for new alias analysis code.
926 (cse_set_around_loop): Likewise.
927 (cse_main): Call init_alias_analysis.
928 * flags.h (flag_alias_check, flag_argument_noalias): Declare.
929 * toplev.c (flag_alias_check, flag_argument_noalias): Define.
930 (f_options): Add new alias checking arguments.
931 (main): Set flag_alias_check when optimizing.
932 * local_alloc (validate_equiv_mem_from_store): Add new arguments
933 to true_dependence.
934 (memref_referenced_p): Likewise.
935 * loop.c (NUM_STORES): Increase to 30.
936 (prescan_loop): Only non-constant calls set unknown_address_altered.
937 (invariant_p): Add new arguments to true_dependence.
938 (record_giv): Initialize unrolled and shared fields.
939 (emit_iv_add_mult): Call record_base_value as needed.
940 * loop.h (struct induction): Add unrolled and shared fields.
941 * unroll.c (unroll_loop): Call record_base_value as needed.
942 (copy_loop_body): Likewise.
943 (final_biv_value): Likewise.
944 (final_giv_value): Likewise.
945 (find_splittable_regs): Likewise. Only create one new pseudo
946 if we have multiple address GIVs that were combined with the same
947 dst_reg GIV. Note when a new register is created due to unrolling.
948 * rtl.c (reg_note_name): Add REG_NOALIAS.
949 * rtl.h (enum reg_note): Similarly.
950 (rtx_varies_p, may_trap_p, side_effects_p): Declare.
951 (volatile_refs_p, volatile_insn_p, remove_note): Likewise.
952 (note_stores, refers_to_regno_p, reg_overlap_mentioned_p): Likewise.
953 (true_dependence, read_dependence, anti_dependence): Likewise.
954 (output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
955 (mark_user_reg, mark_reg_pointer): Likewise.
956
957
958 * Integrate reload bugfix from Wilon which enables the PA port
959 to bootstrap again.
960 * reload1.c (reload): Sum needs for both OPADDR_ADDR and and
961 OPERAND_ADDRESS when computing how many registers an insn needs.
962 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
963 conflict.
964 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
965 OPADDR_ADDR reload.
966 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
967 in reload_reg_use_in_op_addr do not reach the end.
968 do not reach the end.
969 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
970 RELOAD_FOR_OPERAND_ADDRESS.
