1749 | (main): Set COLLECT_GCC_OPTIONS sooner. | |
1750 | * confiugre.in: Link ../ld/ld.new to collect-ld rather than real-ld. | |
1751 | * tlink.c, hash.c, hash.h: New files. | |
1752 | * Makefile.in (USE_COLLECT2): Always use collect2. | |
1753 | (collect2): Depend on and link in hash.o and tlink.o. | |

1758 | * Integrate alias analysis changes from jfc@mit.edu |
1759 | * Makefile.in (OBJS): Add alias.o | |
1760 | (alias.o): Add dependencies. | |
1761 | * alias.c: New file. | |

9ae8ffe7 | 1763 | (sched_analyze_2): Add new arguments to true_dependence. |
9ae8ffe7 JL |
1764 | (schedule_insns): Always call init_alias_analysis. |
1765 | * calls.c (expand_call): Note calls to malloc, calloc, and realloc; | |
1766 | mark return value from such functions as a pointer and keep track of | |
1767 | them for alias analysis. If a return value from a function is a | |
1768 | pointer, mark it as such. | |
1769 | * combine.c (distribute_notes): Handle REG_NOALIAS. | |
1770 | * cse.c (struct write_data): Delete. No longer needed. | |
1771 | (invalidate): Don't call set_nonvarying_address_components anymore. | |
1772 | Use true_dependence to decide if an entry should be removed from | |
1773 | the hash table. | |
1774 | (invalidate_memory): Remove WRITES argument, simplify appropriately. | |
1775 | Fix all callers. | |
1776 | (note_mem_written): Similarly for WRITE_PTR argument. | |
1777 | (invalidate_from_clobbers): Similarly for W argument. | |

1780 | (cse_rtx_varies_p): New function. Derived from old | |
1781 | cse_rtx_addr_varies_p. | |
1782 | (cse_insn): Remove WRITES_MEMORY and INIT variables and all references. | |
1783 | Don't call note_mem_written anymore. Stack pushes invalidate the stack | |
1784 | pointer if PUSH_ROUNDING is defined. No longer need to call | |
1785 | cse_rtx_addr_varies_p to decide if a MEM should be invalidated. | |
1786 | (skipped_writes_memory): Remove variable. | |
1787 | (invalidate_skipped_set): Simplify and wewrite to use invalidate_memory. | |
1788 | (invalidate_skipped_block): Simplify for new alias analysis code. | |
1789 | (cse_set_around_loop): Likewise. | |
1790 | (cse_main): Call init_alias_analysis. | |
1791 | * flags.h (flag_alias_check, flag_argument_noalias): Declare. | |
1792 | * toplev.c (flag_alias_check, flag_argument_noalias): Define. | |

1794 | (main): Set flag_alias_check when optimizing. | |
1795 | * local_alloc (validate_equiv_mem_from_store): Add new arguments | |
1796 | to true_dependence. | |
1797 | (memref_referenced_p): Likewise. | |
1798 | * loop.c (NUM_STORES): Increase to 30. | |
1799 | (prescan_loop): Only non-constant calls set unknown_address_altered. | |
1800 | (invariant_p): Add new arguments to true_dependence. | |
1801 | (record_giv): Initialize unrolled and shared fields. | |
1802 | (emit_iv_add_mult): Call record_base_value as needed. | |
1803 | * loop.h (struct induction): Add unrolled and shared fields. | |
1804 | * unroll.c (unroll_loop): Call record_base_value as needed. | |
1805 | (copy_loop_body): Likewise. | |
1806 | (final_biv_value): Likewise. | |
1807 | (final_giv_value): Likewise. | |
1808 | (find_splittable_regs): Likewise. Only create one new pseudo | |
1809 | if we have multiple address GIVs that were combined with the same | |
1810 | dst_reg GIV. Note when a new register is created due to unrolling. | |
1811 | * rtl.c (reg_note_name): Add REG_NOALIAS. | |
1812 | * rtl.h (enum reg_note): Similarly. | |
1813 | (rtx_varies_p, may_trap_p, side_effects_p): Declare. | |

1816 | (true_dependence, read_dependence, anti_dependence): Likewise. | |
1817 | (output_dependence, init_alias_analysis, end_alias_analysis): Likewise. | |
1818 | (mark_user_reg, mark_reg_pointer): Likewise. | |

1821 | * Integrate reload bugfix from Wilon which enables the PA port | |
5fa39bfe JL |
1822 | to bootstrap again. |
1823 | * reload1.c (reload): Sum needs for both OPADDR_ADDR and and | |
1824 | OPERAND_ADDRESS when computing how many registers an insn needs. | |
1825 | (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do | |
1826 | conflict. | |
1827 | (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like | |
1828 | OPADDR_ADDR reload. | |
1829 | (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers | |
1830 | in reload_reg_use_in_op_addr do not reach the end. | |
1831 | do not reach the end. | |
1832 | (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with | |
1833 | RELOAD_FOR_OPERAND_ADDRESS. | |
