10181 (alias.o): Add dependencies.
10182 * alias.c: New file.
10183 * sched.c: Remove alias analysis code. It lives in alias.c now.
10184 (sched_analyze_2): Add new arguments to true_dependence.
10185 (schedule_insns): Always call init_alias_analysis.
10186 * calls.c (expand_call): Note calls to malloc, calloc, and realloc;
10187 mark return value from such functions as a pointer and keep track of
10188 them for alias analysis. If a return value from a function is a
10189 pointer, mark it as such.
10190 * combine.c (distribute_notes): Handle REG_NOALIAS.
10191 * cse.c (struct write_data): Delete. No longer needed.
10192 (invalidate): Don't call set_nonvarying_address_components anymore.
10193 Use true_dependence to decide if an entry should be removed from
10195 (invalidate_memory): Remove WRITES argument, simplify appropriately.
10197 (note_mem_written): Similarly for WRITE_PTR argument.
10198 (invalidate_from_clobbers): Similarly for W argument.

10202 cse_rtx_addr_varies_p.
10203 (cse_insn): Remove WRITES_MEMORY and INIT variables and all references.
10204 Don't call note_mem_written anymore. Stack pushes invalidate the stack
10205 pointer if PUSH_ROUNDING is defined. No longer need to call
10206 cse_rtx_addr_varies_p to decide if a MEM should be invalidated.
10207 (skipped_writes_memory): Remove variable.
10208 (invalidate_skipped_set): Simplify and wewrite to use invalidate_memory.
10209 (invalidate_skipped_block): Simplify for new alias analysis code.
10210 (cse_set_around_loop): Likewise.
10211 (cse_main): Call init_alias_analysis.
10212 * flags.h (flag_alias_check, flag_argument_noalias): Declare.
10213 * toplev.c (flag_alias_check, flag_argument_noalias): Define.
10214 (f_options): Add new alias checking arguments.
10215 (main): Set flag_alias_check when optimizing.
10216 * local_alloc (validate_equiv_mem_from_store): Add new arguments
10217 to true_dependence.
10218 (memref_referenced_p): Likewise.
10219 * loop.c (NUM_STORES): Increase to 30.

10225 * unroll.c (unroll_loop): Call record_base_value as needed.
10226 (copy_loop_body): Likewise.
10227 (final_biv_value): Likewise.
10228 (final_giv_value): Likewise.
10229 (find_splittable_regs): Likewise. Only create one new pseudo
10230 if we have multiple address GIVs that were combined with the same
10231 dst_reg GIV. Note when a new register is created due to unrolling.
10232 * rtl.c (reg_note_name): Add REG_NOALIAS.
10233 * rtl.h (enum reg_note): Similarly.
10234 (rtx_varies_p, may_trap_p, side_effects_p): Declare.

10238 (output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
10239 (mark_user_reg, mark_reg_pointer): Likewise.
10242 * Integrate reload bugfix from Wilon which enables the PA port
10243 to bootstrap again.
10244 * reload1.c (reload): Sum needs for both OPADDR_ADDR and
10245 OPERAND_ADDRESS when computing how many registers an insn needs.
10246 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
10248 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
10249 OPADDR_ADDR reload.
10250 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
10251 in reload_reg_use_in_op_addr do not reach the end.
10252 do not reach the end.
10253 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
10254 RELOAD_FOR_OPERAND_ADDRESS.
