9ae8ffe7 JL |
406 | (schedule_insns): Always call init_alias_analysis. |
407 | * calls.c (expand_call): Note calls to malloc, calloc, and realloc; | |
408 | mark return value from such functions as a pointer and keep track of | |
409 | them for alias analysis. If a return value from a function is a | |
410 | pointer, mark it as such. | |

412 | * cse.c (struct write_data): Delete. No longer needed. | |
413 | (invalidate): Don't call set_nonvarying_address_components anymore. | |
414 | Use true_dependence to decide if an entry should be removed from | |
415 | the hash table. | |
416 | (invalidate_memory): Remove WRITES argument, simplify appropriately. | |
417 | Fix all callers. | |
418 | (note_mem_written): Similarly for WRITE_PTR argument. | |

423 | cse_rtx_addr_varies_p. | |
424 | (cse_insn): Remove WRITES_MEMORY and INIT variables and all references. | |
425 | Don't call note_mem_written anymore. Stack pushes invalidate the stack | |
426 | pointer if PUSH_ROUNDING is defined. No longer need to call | |
427 | cse_rtx_addr_varies_p to decide if a MEM should be invalidated. | |
428 | (skipped_writes_memory): Remove variable. | |
429 | (invalidate_skipped_set): Simplify and wewrite to use invalidate_memory. | |

448 | (final_biv_value): Likewise. | |
449 | (final_giv_value): Likewise. | |
450 | (find_splittable_regs): Likewise. Only create one new pseudo | |
451 | if we have multiple address GIVs that were combined with the same | |
452 | dst_reg GIV. Note when a new register is created due to unrolling. | |
453 | * rtl.c (reg_note_name): Add REG_NOALIAS. | |
454 | * rtl.h (enum reg_note): Similarly. | |

5fa39bfe JL |
464 | to bootstrap again. |
465 | * reload1.c (reload): Sum needs for both OPADDR_ADDR and and | |
466 | OPERAND_ADDRESS when computing how many registers an insn needs. | |
467 | (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do | |
468 | conflict. | |
469 | (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like | |
470 | OPADDR_ADDR reload. | |
471 | (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers | |
