2430 (main): Set COLLECT_GCC_OPTIONS sooner.
2431 * confiugre.in: Link ../ld/ld.new to collect-ld rather than real-ld.
2432 * tlink.c, hash.c, hash.h: New files.
2433 * Makefile.in (USE_COLLECT2): Always use collect2.
2434 (collect2): Depend on and link in hash.o and tlink.o.
2435 (tlink.o, hash.o): Add dependencies.
2437 Mon Aug 11 10:04:49 1997 Jeffrey A Law (law@cygnus.com)
2439 * Integrate alias analysis changes from jfc@mit.edu
2440 * Makefile.in (OBJS): Add alias.o
2441 (alias.o): Add dependencies.
2442 * alias.c: New file.
2443 * sched.c: Remove alias analysis code. It lives in alias.c now.
2444 (sched_analyze_2): Add new arguments to true_dependence.
2445 (schedule_insns): Always call init_alias_analysis.
2446 * calls.c (expand_call): Note calls to malloc, calloc, and realloc;
2447 mark return value from such functions as a pointer and keep track of
2448 them for alias analysis. If a return value from a function is a
2449 pointer, mark it as such.
2450 * combine.c (distribute_notes): Handle REG_NOALIAS.
2451 * cse.c (struct write_data): Delete. No longer needed.
2452 (invalidate): Don't call set_nonvarying_address_components anymore.
2453 Use true_dependence to decide if an entry should be removed from
2455 (invalidate_memory): Remove WRITES argument, simplify appropriately.
2457 (note_mem_written): Similarly for WRITE_PTR argument.
2458 (invalidate_from_clobbers): Similarly for W argument.
2459 (invalidate_for_call): Remove memory elements from the hash table.
2460 (refers_to_mem_p, cse_rtx_addr_varies_p): Deleted.
2461 (cse_rtx_varies_p): New function. Derived from old
2462 cse_rtx_addr_varies_p.
2463 (cse_insn): Remove WRITES_MEMORY and INIT variables and all references.
2464 Don't call note_mem_written anymore. Stack pushes invalidate the stack
2465 pointer if PUSH_ROUNDING is defined. No longer need to call
2466 cse_rtx_addr_varies_p to decide if a MEM should be invalidated.
2467 (skipped_writes_memory): Remove variable.
2468 (invalidate_skipped_set): Simplify and wewrite to use invalidate_memory.
2469 (invalidate_skipped_block): Simplify for new alias analysis code.
2470 (cse_set_around_loop): Likewise.
2471 (cse_main): Call init_alias_analysis.
2472 * flags.h (flag_alias_check, flag_argument_noalias): Declare.
2473 * toplev.c (flag_alias_check, flag_argument_noalias): Define.
2474 (f_options): Add new alias checking arguments.
2475 (main): Set flag_alias_check when optimizing.
2476 * local_alloc (validate_equiv_mem_from_store): Add new arguments
2478 (memref_referenced_p): Likewise.
2479 * loop.c (NUM_STORES): Increase to 30.
2480 (prescan_loop): Only non-constant calls set unknown_address_altered.
2481 (invariant_p): Add new arguments to true_dependence.
2482 (record_giv): Initialize unrolled and shared fields.
2483 (emit_iv_add_mult): Call record_base_value as needed.
2484 * loop.h (struct induction): Add unrolled and shared fields.
2485 * unroll.c (unroll_loop): Call record_base_value as needed.
2486 (copy_loop_body): Likewise.
2487 (final_biv_value): Likewise.
2488 (final_giv_value): Likewise.
2489 (find_splittable_regs): Likewise. Only create one new pseudo
2490 if we have multiple address GIVs that were combined with the same
2491 dst_reg GIV. Note when a new register is created due to unrolling.
2492 * rtl.c (reg_note_name): Add REG_NOALIAS.
2493 * rtl.h (enum reg_note): Similarly.
2494 (rtx_varies_p, may_trap_p, side_effects_p): Declare.
2495 (volatile_refs_p, volatile_insn_p, remove_note): Likewise.
2496 (note_stores, refers_to_regno_p, reg_overlap_mentioned_p): Likewise.
2497 (true_dependence, read_dependence, anti_dependence): Likewise.
2498 (output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
2499 (mark_user_reg, mark_reg_pointer): Likewise.
2502 * Integrate reload bugfix from Wilon which enables the PA port
2504 * reload1.c (reload): Sum needs for both OPADDR_ADDR and and
2505 OPERAND_ADDRESS when computing how many registers an insn needs.
2506 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
2508 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
2510 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
2511 in reload_reg_use_in_op_addr do not reach the end.
2512 do not reach the end.
2513 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
2514 RELOAD_FOR_OPERAND_ADDRESS.

2518 * egcs project officially starts.
