1656 * rtti.c: Include target.h.
1657 (emit_support_tinfos): If ! targetm.cxx.library_rtti_comdat (),
1658 don't emit typeinfo for fundamental types as weak.
1659 * Make-lang.in (cp/rtti.o): Update and correct dependencies.
1661 2007-01-08 Richard Guenther <rguenther@suse.de>
1663 * cvt.c (cp_convert_to_pointer): Use build_int_cst_type.
1665 2007-01-08 Mark Shinwell <shinwell@codesourcery.com>
1667 * call.c (standard_conversion): Pass flag to
1668 vector_types_convertible_p to disallow emission of note.
1669 * typeck.c (convert_for_assignment): Pass flag to
1670 vector_types_convertible_p to allow emission of note.
1671 (ptr_reasonably_similar): Pass flag to vector_types_convertible_p
1672 to disallow emission of note.
1674 2007-01-07 Manuel Lopez-Ibanez <manu@gcc.gnu.org>
1677 * typeck.c (build_binary_op): Call overflow_warning if
1678 TREE_OVERFLOW_P is true for the result and not for any of the
1681 2007-01-06 Lee Millward <lee.millward@codesourcery.com>
1684 * class.c (add_method): Don't wait until template
1685 instantiation time to complain about duplicate methods.
1687 2007-01-05 Manuel Lopez-Ibanez <manu@gcc.gnu.org>
1690 * semantics.c (finish_unary_op_expr): Warn only if result
1691 overflowed and operands did not.
1693 2007-01-05 Ian Lance Taylor <iant@google.com>
1695 * typeck.c (build_binary_op): Warn about comparing a non-weak
1698 2007-01-05 Douglas Gregor <doug.gregor@gmail.com>
1700 * pt.c (tsubst): Propagate the need for structural equality checks
1701 when reducing the level of template parameters.
1703 2007-01-03 Kazu Hirata <kazu@codesourcery.com>
1705 * pt.c: Fix a comment typo.
1707 2007-01-02 Ian Lance Taylor <iant@google.com>
1709 * semantics.c (maybe_convert_cond): Optionally warn when using an
1710 assignment as a condition.
1711 * typeck.c (convert_for_assignment): Optionally warn about
1712 assigning the result of an assignment to a bool.
1714 2007-01-02 Douglas Gregor <doug.gregor@gmail.com>
1716 * pt.c (canonical_template_parms): Correct typo in comment.
1718 2007-01-02 Douglas Gregor <doug.gregor@gmail.com>
1720 * typeck.c (structural_comptypes): Renamed from "comptypes".
1721 (comptypes): Use canonical type information to perform fast type
1722 comparison. When VERIFY_CANONICAL_TYPES, verify that the
1723 canonical type comparison returns the same results as we would see
1724 from the current, structural check. Support COMPARE_STRUCTURAL
1725 when we need structural checks.
1726 * decl.c (typename_compare): Fix comment.
1727 (build_typename_type): TYPENAME_TYPE nodes require structural
1728 equality checks, because they resolve different based on the
1730 (make_unbound_class_template): UNBOUND_CLASS_TEMPLATE nodes
1731 require structural equality checks (for now).
1732 (build_ptrmemfunc_type): Build the canonical pointer to member
1734 (compute_array_index_type): Whenever we build a new index type
1735 to represent the size of an array in a template, we need to mark
1736 this index type as requiring structural equality. This goes for
1737 arrays with value-dependent sizes with the current ABI, or all
1739 * tree.c (cplus_array_hash): New.
1740 (struct cplus_array_info): New.
1741 (cplus_array_compare): New.
1742 (cplus_array_htab): New.
1743 (build_cplus_array_type_1): Use a hash table to cache the array
1744 types we build. Build the canonical array type for each array
1746 (cp_build_qualified_type_real): When building a cv-qualified array
1747 type, use the hash table of array types and build canonical array
1749 (bind_template_template_parm): BOUND_TEMPLATE_TEMPLATE_PARM nodes
1750 use structural equality (for now).
1751 * cp-tree.h (COMPARE_STRUCTURAL): New.
1752 * pt.c (canonical_template_parms): New.
1753 (canonical_type_parameter): New.
1754 (process_template_parm): Find the canonical type parameter.
1755 (lookup_template_class): When we have named the primary template
1756 type, set the canonical type for our template class to the primary
1757 template type. If any of the template arguments need structural
1758 equality checks, the template class needs structural equality
1760 (tsubst): When reducing the level of a template template
1761 parameter, we require structural equality tests for the resulting
1762 parameter because its template parameters have not had their types
1763 canonicalized. When reducing a template type parameter, find the
1764 canonical reduced type parameter.
1765 (any_template_arguments_need_structural_equality_p): New.
