5276 (collect2): Depend on and link in hash.o and tlink.o.
5277 (tlink.o, hash.o): Add dependencies.
5279 Mon Aug 11 10:04:49 1997 Jeffrey A Law (law@cygnus.com)
5281 * Integrate alias analysis changes from jfc@mit.edu
5282 * Makefile.in (OBJS): Add alias.o
5283 (alias.o): Add dependencies.
5284 * alias.c: New file.
5285 * sched.c: Remove alias analysis code. It lives in alias.c now.
5286 (sched_analyze_2): Add new arguments to true_dependence.
5287 (schedule_insns): Always call init_alias_analysis.
5288 * calls.c (expand_call): Note calls to malloc, calloc, and realloc;
5289 mark return value from such functions as a pointer and keep track of
5290 them for alias analysis. If a return value from a function is a
5291 pointer, mark it as such.
5292 * combine.c (distribute_notes): Handle REG_NOALIAS.
5293 * cse.c (struct write_data): Delete. No longer needed.
5294 (invalidate): Don't call set_nonvarying_address_components anymore.
5295 Use true_dependence to decide if an entry should be removed from
5297 (invalidate_memory): Remove WRITES argument, simplify appropriately.
5299 (note_mem_written): Similarly for WRITE_PTR argument.
5300 (invalidate_from_clobbers): Similarly for W argument.
5301 (invalidate_for_call): Remove memory elements from the hash table.
5302 (refers_to_mem_p, cse_rtx_addr_varies_p): Deleted.
5303 (cse_rtx_varies_p): New function. Derived from old
5304 cse_rtx_addr_varies_p.
5305 (cse_insn): Remove WRITES_MEMORY and INIT variables and all references.
5306 Don't call note_mem_written anymore. Stack pushes invalidate the stack
5307 pointer if PUSH_ROUNDING is defined. No longer need to call
5308 cse_rtx_addr_varies_p to decide if a MEM should be invalidated.
5309 (skipped_writes_memory): Remove variable.
5310 (invalidate_skipped_set): Simplify and wewrite to use invalidate_memory.
5311 (invalidate_skipped_block): Simplify for new alias analysis code.
5312 (cse_set_around_loop): Likewise.
5313 (cse_main): Call init_alias_analysis.
5314 * flags.h (flag_alias_check, flag_argument_noalias): Declare.
5315 * toplev.c (flag_alias_check, flag_argument_noalias): Define.
5316 (f_options): Add new alias checking arguments.
5317 (main): Set flag_alias_check when optimizing.
5318 * local_alloc (validate_equiv_mem_from_store): Add new arguments
5320 (memref_referenced_p): Likewise.
5321 * loop.c (NUM_STORES): Increase to 30.
5322 (prescan_loop): Only non-constant calls set unknown_address_altered.
5323 (invariant_p): Add new arguments to true_dependence.
5324 (record_giv): Initialize unrolled and shared fields.
5325 (emit_iv_add_mult): Call record_base_value as needed.
5326 * loop.h (struct induction): Add unrolled and shared fields.
5327 * unroll.c (unroll_loop): Call record_base_value as needed.
5328 (copy_loop_body): Likewise.
5329 (final_biv_value): Likewise.
5330 (final_giv_value): Likewise.
5331 (find_splittable_regs): Likewise. Only create one new pseudo
5332 if we have multiple address GIVs that were combined with the same
5333 dst_reg GIV. Note when a new register is created due to unrolling.
5334 * rtl.c (reg_note_name): Add REG_NOALIAS.
5335 * rtl.h (enum reg_note): Similarly.
5336 (rtx_varies_p, may_trap_p, side_effects_p): Declare.
5337 (volatile_refs_p, volatile_insn_p, remove_note): Likewise.
5338 (note_stores, refers_to_regno_p, reg_overlap_mentioned_p): Likewise.
5339 (true_dependence, read_dependence, anti_dependence): Likewise.
5340 (output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
5341 (mark_user_reg, mark_reg_pointer): Likewise.
5344 * Integrate reload bugfix from Wilon which enables the PA port
5346 * reload1.c (reload): Sum needs for both OPADDR_ADDR and and
5347 OPERAND_ADDRESS when computing how many registers an insn needs.
5348 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
5350 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
5352 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
5353 in reload_reg_use_in_op_addr do not reach the end.
5354 do not reach the end.
5355 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
5356 RELOAD_FOR_OPERAND_ADDRESS.

5360 * egcs project officially starts.
