2434 (process_command): Set include_prefixes from COMPILER_PATH.
2435 (main): Set COLLECT_GCC_OPTIONS sooner.
2436 * confiugre.in: Link ../ld/ld.new to collect-ld rather than real-ld.
2437 * tlink.c, hash.c, hash.h: New files.
2438 * Makefile.in (USE_COLLECT2): Always use collect2.
2439 (collect2): Depend on and link in hash.o and tlink.o.
2440 (tlink.o, hash.o): Add dependencies.
2442 Mon Aug 11 10:04:49 1997 Jeffrey A Law (law@cygnus.com)
2444 * Integrate alias analysis changes from jfc@mit.edu
2445 * Makefile.in (OBJS): Add alias.o
2446 (alias.o): Add dependencies.
2447 * alias.c: New file.
2448 * sched.c: Remove alias analysis code. It lives in alias.c now.
2449 (sched_analyze_2): Add new arguments to true_dependence.
2450 (schedule_insns): Always call init_alias_analysis.
2451 * calls.c (expand_call): Note calls to malloc, calloc, and realloc;
2452 mark return value from such functions as a pointer and keep track of
2453 them for alias analysis. If a return value from a function is a
2454 pointer, mark it as such.
2455 * combine.c (distribute_notes): Handle REG_NOALIAS.
2456 * cse.c (struct write_data): Delete. No longer needed.
2457 (invalidate): Don't call set_nonvarying_address_components anymore.
2458 Use true_dependence to decide if an entry should be removed from
2460 (invalidate_memory): Remove WRITES argument, simplify appropriately.
2462 (note_mem_written): Similarly for WRITE_PTR argument.
2463 (invalidate_from_clobbers): Similarly for W argument.
2464 (invalidate_for_call): Remove memory elements from the hash table.
2465 (refers_to_mem_p, cse_rtx_addr_varies_p): Deleted.
2466 (cse_rtx_varies_p): New function. Derived from old
2467 cse_rtx_addr_varies_p.
2468 (cse_insn): Remove WRITES_MEMORY and INIT variables and all references.
2469 Don't call note_mem_written anymore. Stack pushes invalidate the stack
2470 pointer if PUSH_ROUNDING is defined. No longer need to call
2471 cse_rtx_addr_varies_p to decide if a MEM should be invalidated.
2472 (skipped_writes_memory): Remove variable.
2473 (invalidate_skipped_set): Simplify and wewrite to use invalidate_memory.
2474 (invalidate_skipped_block): Simplify for new alias analysis code.
2475 (cse_set_around_loop): Likewise.
2476 (cse_main): Call init_alias_analysis.
2477 * flags.h (flag_alias_check, flag_argument_noalias): Declare.
2478 * toplev.c (flag_alias_check, flag_argument_noalias): Define.
2479 (f_options): Add new alias checking arguments.
2480 (main): Set flag_alias_check when optimizing.
2481 * local_alloc (validate_equiv_mem_from_store): Add new arguments
2483 (memref_referenced_p): Likewise.
2484 * loop.c (NUM_STORES): Increase to 30.
2485 (prescan_loop): Only non-constant calls set unknown_address_altered.
2486 (invariant_p): Add new arguments to true_dependence.
2487 (record_giv): Initialize unrolled and shared fields.
2488 (emit_iv_add_mult): Call record_base_value as needed.
2489 * loop.h (struct induction): Add unrolled and shared fields.
2490 * unroll.c (unroll_loop): Call record_base_value as needed.
2491 (copy_loop_body): Likewise.
2492 (final_biv_value): Likewise.
2493 (final_giv_value): Likewise.
2494 (find_splittable_regs): Likewise. Only create one new pseudo
2495 if we have multiple address GIVs that were combined with the same
2496 dst_reg GIV. Note when a new register is created due to unrolling.
2497 * rtl.c (reg_note_name): Add REG_NOALIAS.
2498 * rtl.h (enum reg_note): Similarly.
2499 (rtx_varies_p, may_trap_p, side_effects_p): Declare.
2500 (volatile_refs_p, volatile_insn_p, remove_note): Likewise.
2501 (note_stores, refers_to_regno_p, reg_overlap_mentioned_p): Likewise.
2502 (true_dependence, read_dependence, anti_dependence): Likewise.
2503 (output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
2504 (mark_user_reg, mark_reg_pointer): Likewise.
2507 * Integrate reload bugfix from Wilon which enables the PA port
2509 * reload1.c (reload): Sum needs for both OPADDR_ADDR and and
2510 OPERAND_ADDRESS when computing how many registers an insn needs.
2511 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
2513 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
2515 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
2516 in reload_reg_use_in_op_addr do not reach the end.
2517 do not reach the end.
2518 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
2519 RELOAD_FOR_OPERAND_ADDRESS.
