965f4536 | 826 | |
3eb54e5f ILT |
827 | Remove definition of HOST_WIDE_INT. Change calls |

829 | hardcoded MASK, which is safe since this is the source | |
830 | character set). | |
965f4536 | 831 | |
3eb54e5f ILT |
832 | * cppexp.c: Bring over changes to cpp_parse_escape from cccp.c |
833 | to handle wide character constants in #if directives. The | |
834 | function now returns a HOST_WIDE_INT, and takes a third | |
835 | argument which is a binary mask for all legal values (0x00ff | |
836 | for 8-bit `char', 0xffff for 16-bit `wchar_t', etc.) Define | |
837 | MAX_CHAR_TYPE_MASK and MAX_WCHAR_TYPE_MASK. Change callers of | |
838 | cpp_parse_escape to match. [Fixes c-torture/execute/widechar-1.c] | |

3713 | if replace is true. Return a value. | |
3714 | When changing address reload types for operands that didn't get | |

3746 | expressions if the actual addressing can't be changed to match the | |
3747 | auto_inc. | |
3748 | (choose_reload_regs): For inheritance, replace | |
3749 | reload_reg_free_before_p test with reload_reg_used_at_all test, and | |
3750 | remove stand-alone reload_reg_used_at_all test. | |
3751 | Use reload_out_reg to determine which reload regs have output reloads. | |
3752 | Treat reload_override_in more similar to inherited reloads. | |

3773 | in oldequiv code. | |
3774 | Add code to call delete_output_reload for stores with no matching load. | |
3775 | Set / use spill_reg_stored_to. | |
3776 | Handle case where secondary output reload uses a temporary, but | |
3777 | actual store isn't found. | |
3778 | When looking for a store of a value not loaded in order to call | |
3779 | delete_output_reload, count_occurrences should return 0 for no | |
3780 | loads; but discount inherited input reloadill_reg_stored_to. | |

3782 | callers. | |

3794 | for the address reload we are considering. | |
3795 | (count_occurrences): Use rtx_equal_p for MEMs. | |
3796 | (inc_for_reload): Return instruction that stores into RELOADREG. | |
3797 | New argument two, IN, and rtx. Changed all callers. | |
3798 | (calculate_needs_all_insns, reload_as_needed): | |
3799 | Don't clear after_call for a CLOBBER. | |
3800 | Keep track of how many hard registers need to be copied from | |
3801 | after_call, and don't clear after_call before we have seen | |
3802 | that much copies, or we see a different instruction. | |
