5288 (process_command): Set include_prefixes from COMPILER_PATH.
5289 (main): Set COLLECT_GCC_OPTIONS sooner.
5290 * confiugre.in: Link ../ld/ld.new to collect-ld rather than real-ld.
5291 * tlink.c, hash.c, hash.h: New files.
5292 * Makefile.in (USE_COLLECT2): Always use collect2.
5293 (collect2): Depend on and link in hash.o and tlink.o.
5294 (tlink.o, hash.o): Add dependencies.
5296 Mon Aug 11 10:04:49 1997 Jeffrey A Law (law@cygnus.com)
5298 * Integrate alias analysis changes from jfc@mit.edu
5299 * Makefile.in (OBJS): Add alias.o
5300 (alias.o): Add dependencies.
5301 * alias.c: New file.
5302 * sched.c: Remove alias analysis code. It lives in alias.c now.
5303 (sched_analyze_2): Add new arguments to true_dependence.
5304 (schedule_insns): Always call init_alias_analysis.
5305 * calls.c (expand_call): Note calls to malloc, calloc, and realloc;
5306 mark return value from such functions as a pointer and keep track of
5307 them for alias analysis. If a return value from a function is a
5308 pointer, mark it as such.
5309 * combine.c (distribute_notes): Handle REG_NOALIAS.
5310 * cse.c (struct write_data): Delete. No longer needed.
5311 (invalidate): Don't call set_nonvarying_address_components anymore.
5312 Use true_dependence to decide if an entry should be removed from
5314 (invalidate_memory): Remove WRITES argument, simplify appropriately.
5316 (note_mem_written): Similarly for WRITE_PTR argument.
5317 (invalidate_from_clobbers): Similarly for W argument.
5318 (invalidate_for_call): Remove memory elements from the hash table.
5319 (refers_to_mem_p, cse_rtx_addr_varies_p): Deleted.
5320 (cse_rtx_varies_p): New function. Derived from old
5321 cse_rtx_addr_varies_p.
5322 (cse_insn): Remove WRITES_MEMORY and INIT variables and all references.
5323 Don't call note_mem_written anymore. Stack pushes invalidate the stack
5324 pointer if PUSH_ROUNDING is defined. No longer need to call
5325 cse_rtx_addr_varies_p to decide if a MEM should be invalidated.
5326 (skipped_writes_memory): Remove variable.
5327 (invalidate_skipped_set): Simplify and wewrite to use invalidate_memory.
5328 (invalidate_skipped_block): Simplify for new alias analysis code.
5329 (cse_set_around_loop): Likewise.
5330 (cse_main): Call init_alias_analysis.
5331 * flags.h (flag_alias_check, flag_argument_noalias): Declare.
5332 * toplev.c (flag_alias_check, flag_argument_noalias): Define.
5333 (f_options): Add new alias checking arguments.
5334 (main): Set flag_alias_check when optimizing.
5335 * local_alloc (validate_equiv_mem_from_store): Add new arguments
5337 (memref_referenced_p): Likewise.
5338 * loop.c (NUM_STORES): Increase to 30.
5339 (prescan_loop): Only non-constant calls set unknown_address_altered.
5340 (invariant_p): Add new arguments to true_dependence.
5341 (record_giv): Initialize unrolled and shared fields.
5342 (emit_iv_add_mult): Call record_base_value as needed.
5343 * loop.h (struct induction): Add unrolled and shared fields.
5344 * unroll.c (unroll_loop): Call record_base_value as needed.
5345 (copy_loop_body): Likewise.
5346 (final_biv_value): Likewise.
5347 (final_giv_value): Likewise.
5348 (find_splittable_regs): Likewise. Only create one new pseudo
5349 if we have multiple address GIVs that were combined with the same
5350 dst_reg GIV. Note when a new register is created due to unrolling.
5351 * rtl.c (reg_note_name): Add REG_NOALIAS.
5352 * rtl.h (enum reg_note): Similarly.
5353 (rtx_varies_p, may_trap_p, side_effects_p): Declare.
5354 (volatile_refs_p, volatile_insn_p, remove_note): Likewise.
5355 (note_stores, refers_to_regno_p, reg_overlap_mentioned_p): Likewise.
5356 (true_dependence, read_dependence, anti_dependence): Likewise.
5357 (output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
5358 (mark_user_reg, mark_reg_pointer): Likewise.
5361 * Integrate reload bugfix from Wilon which enables the PA port
5363 * reload1.c (reload): Sum needs for both OPADDR_ADDR and and
5364 OPERAND_ADDRESS when computing how many registers an insn needs.
5365 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
5367 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
5369 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
5370 in reload_reg_use_in_op_addr do not reach the end.
5371 do not reach the end.
5372 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
5373 RELOAD_FOR_OPERAND_ADDRESS.

5377 * egcs project officially starts.
