2927 (regmove_dump_file, regmove_time): Define.
2928 (fatal_insn): Close the regmove dump file.
2929 (compile_file): Initialize regmove_time; open/close the regmove dump
2930 file as needed. Print regmove time as needed.

2932 RTL after regmove if requested.

2948 * Makefile.in (USE_COLLECT2): Always use collect2.
2949 (collect2): Depend on and link in hash.o and tlink.o.

2952 Mon Aug 11 10:04:49 1997 Jeffrey A Law (law@cygnus.com)
2954 * Integrate alias analysis changes from jfc@mit.edu
2955 * Makefile.in (OBJS): Add alias.o
2956 (alias.o): Add dependencies.
2957 * alias.c: New file.
2958 * sched.c: Remove alias analysis code. It lives in alias.c now.
2959 (sched_analyze_2): Add new arguments to true_dependence.
2960 (schedule_insns): Always call init_alias_analysis.
2961 * calls.c (expand_call): Note calls to malloc, calloc, and realloc;
2962 mark return value from such functions as a pointer and keep track of
2963 them for alias analysis. If a return value from a function is a
2964 pointer, mark it as such.
2965 * combine.c (distribute_notes): Handle REG_NOALIAS.
2966 * cse.c (struct write_data): Delete. No longer needed.
2967 (invalidate): Don't call set_nonvarying_address_components anymore.
2968 Use true_dependence to decide if an entry should be removed from
2970 (invalidate_memory): Remove WRITES argument, simplify appropriately.
2972 (note_mem_written): Similarly for WRITE_PTR argument.
2973 (invalidate_from_clobbers): Similarly for W argument.
2974 (invalidate_for_call): Remove memory elements from the hash table.
2975 (refers_to_mem_p, cse_rtx_addr_varies_p): Deleted.

2977 cse_rtx_addr_varies_p.
2978 (cse_insn): Remove WRITES_MEMORY and INIT variables and all references.
2979 Don't call note_mem_written anymore. Stack pushes invalidate the stack
2980 pointer if PUSH_ROUNDING is defined. No longer need to call
2981 cse_rtx_addr_varies_p to decide if a MEM should be invalidated.
2982 (skipped_writes_memory): Remove variable.
2983 (invalidate_skipped_set): Simplify and wewrite to use invalidate_memory.
2984 (invalidate_skipped_block): Simplify for new alias analysis code.
2985 (cse_set_around_loop): Likewise.
2986 (cse_main): Call init_alias_analysis.
2987 * flags.h (flag_alias_check, flag_argument_noalias): Declare.
2988 * toplev.c (flag_alias_check, flag_argument_noalias): Define.
2989 (f_options): Add new alias checking arguments.

3001 (copy_loop_body): Likewise.
3002 (final_biv_value): Likewise.
3003 (final_giv_value): Likewise.
3004 (find_splittable_regs): Likewise. Only create one new pseudo
3005 if we have multiple address GIVs that were combined with the same
3006 dst_reg GIV. Note when a new register is created due to unrolling.
3007 * rtl.c (reg_note_name): Add REG_NOALIAS.
3008 * rtl.h (enum reg_note): Similarly.
3009 (rtx_varies_p, may_trap_p, side_effects_p): Declare.
3010 (volatile_refs_p, volatile_insn_p, remove_note): Likewise.
3011 (note_stores, refers_to_regno_p, reg_overlap_mentioned_p): Likewise.
3012 (true_dependence, read_dependence, anti_dependence): Likewise.
3013 (output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
3014 (mark_user_reg, mark_reg_pointer): Likewise.
3017 * Integrate reload bugfix from Wilon which enables the PA port
3019 * reload1.c (reload): Sum needs for both OPADDR_ADDR and and
3020 OPERAND_ADDRESS when computing how many registers an insn needs.
3021 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
3023 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
3025 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
3026 in reload_reg_use_in_op_addr do not reach the end.
3027 do not reach the end.
3028 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
3029 RELOAD_FOR_OPERAND_ADDRESS.
