5467 | * confiugre.in: Link ../ld/ld.new to collect-ld rather than real-ld. | |
5468 | * tlink.c, hash.c, hash.h: New files. | |
5469 | * Makefile.in (USE_COLLECT2): Always use collect2. | |
5470 | (collect2): Depend on and link in hash.o and tlink.o. | |
5471 | (tlink.o, hash.o): Add dependencies. | |

5475 | * Integrate alias analysis changes from jfc@mit.edu |
5476 | * Makefile.in (OBJS): Add alias.o | |
5477 | (alias.o): Add dependencies. | |
5478 | * alias.c: New file. | |
5479 | * sched.c: Remove alias analysis code. It lives in alias.c now. | |
9ae8ffe7 | 5480 | (sched_analyze_2): Add new arguments to true_dependence. |
9ae8ffe7 JL |
5481 | (schedule_insns): Always call init_alias_analysis. |
5482 | * calls.c (expand_call): Note calls to malloc, calloc, and realloc; | |
5483 | mark return value from such functions as a pointer and keep track of | |
5484 | them for alias analysis. If a return value from a function is a | |
5485 | pointer, mark it as such. | |
5486 | * combine.c (distribute_notes): Handle REG_NOALIAS. | |
5487 | * cse.c (struct write_data): Delete. No longer needed. | |
5488 | (invalidate): Don't call set_nonvarying_address_components anymore. | |
5489 | Use true_dependence to decide if an entry should be removed from | |
5490 | the hash table. | |
5491 | (invalidate_memory): Remove WRITES argument, simplify appropriately. | |
5492 | Fix all callers. | |
5493 | (note_mem_written): Similarly for WRITE_PTR argument. | |
5494 | (invalidate_from_clobbers): Similarly for W argument. | |
5495 | (invalidate_for_call): Remove memory elements from the hash table. | |
5496 | (refers_to_mem_p, cse_rtx_addr_varies_p): Deleted. | |
5497 | (cse_rtx_varies_p): New function. Derived from old | |
5498 | cse_rtx_addr_varies_p. | |
5499 | (cse_insn): Remove WRITES_MEMORY and INIT variables and all references. | |
5500 | Don't call note_mem_written anymore. Stack pushes invalidate the stack | |
5501 | pointer if PUSH_ROUNDING is defined. No longer need to call | |
5502 | cse_rtx_addr_varies_p to decide if a MEM should be invalidated. | |
5503 | (skipped_writes_memory): Remove variable. | |
5504 | (invalidate_skipped_set): Simplify and wewrite to use invalidate_memory. | |
5505 | (invalidate_skipped_block): Simplify for new alias analysis code. | |
5506 | (cse_set_around_loop): Likewise. | |
5507 | (cse_main): Call init_alias_analysis. | |
5508 | * flags.h (flag_alias_check, flag_argument_noalias): Declare. | |
5509 | * toplev.c (flag_alias_check, flag_argument_noalias): Define. | |
5510 | (f_options): Add new alias checking arguments. | |
5511 | (main): Set flag_alias_check when optimizing. | |
5512 | * local_alloc (validate_equiv_mem_from_store): Add new arguments | |
5513 | to true_dependence. | |
5514 | (memref_referenced_p): Likewise. | |
5515 | * loop.c (NUM_STORES): Increase to 30. | |
5516 | (prescan_loop): Only non-constant calls set unknown_address_altered. | |
5517 | (invariant_p): Add new arguments to true_dependence. | |
5518 | (record_giv): Initialize unrolled and shared fields. | |
5519 | (emit_iv_add_mult): Call record_base_value as needed. | |
5520 | * loop.h (struct induction): Add unrolled and shared fields. | |
5521 | * unroll.c (unroll_loop): Call record_base_value as needed. | |
5522 | (copy_loop_body): Likewise. | |
5523 | (final_biv_value): Likewise. | |
5524 | (final_giv_value): Likewise. | |
5525 | (find_splittable_regs): Likewise. Only create one new pseudo | |
5526 | if we have multiple address GIVs that were combined with the same | |
5527 | dst_reg GIV. Note when a new register is created due to unrolling. | |
5528 | * rtl.c (reg_note_name): Add REG_NOALIAS. | |
5529 | * rtl.h (enum reg_note): Similarly. | |
5530 | (rtx_varies_p, may_trap_p, side_effects_p): Declare. | |
5531 | (volatile_refs_p, volatile_insn_p, remove_note): Likewise. | |
5532 | (note_stores, refers_to_regno_p, reg_overlap_mentioned_p): Likewise. | |
5533 | (true_dependence, read_dependence, anti_dependence): Likewise. | |
5534 | (output_dependence, init_alias_analysis, end_alias_analysis): Likewise. | |
5535 | (mark_user_reg, mark_reg_pointer): Likewise. | |
5536 | ||
5537 | ||
5538 | * Integrate reload bugfix from Wilon which enables the PA port | |
5fa39bfe JL |
5539 | to bootstrap again. |
5540 | * reload1.c (reload): Sum needs for both OPADDR_ADDR and and | |
5541 | OPERAND_ADDRESS when computing how many registers an insn needs. | |
5542 | (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do | |
5543 | conflict. | |
5544 | (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like | |
5545 | OPADDR_ADDR reload. | |
5546 | (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers | |
5547 | in reload_reg_use_in_op_addr do not reach the end. | |
5548 | do not reach the end. | |
5549 | (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with | |
5550 | RELOAD_FOR_OPERAND_ADDRESS. | |
