    modify_all_vtables): New routines.
    * class.c (finish_struct): Added arguemnt to prepare_fresh_vtable
    call.  General cleanup on how pending_hard_virtuals are handled.
    General cleanup on modifying vtables.  Use finish_vtbls, instead of
    unmark_finished_struct.
    * cp-tree.h (init_vtbl_ptrs, expand_direct_vtbls_init,
    get_first_matching_virtual, get_matching_virtual,

    * decl.c (grokfndecl): General cleanup.
    * decl.c (finish_function): Change init_vtbl_ptrs call to
    expand_direct_vtbls_init.  Change expand_vbase_vtables_init call to
    expand_indirect_vtbls_init.
    * init.c (expand_virtual_init): Remove unneeded argument.
    * init.c (init_vtbl_ptrs): Rename to expand_direct_vtbls_init, added

    used for vtable pointer initialization from virtual bases.
    * init.c (emit_base_init): Change expand_vbase_vtables_init call to
    expand_indirect_vtbls_init.  Change init_vtbl_ptrs call to

    DECL_CONTEXT.  That is now done in a cleaner way in
    modify_vtable_entry and add_virtual_function.
    * search.c (expand_vbase_vtables_init): Rename to
    expand_indirect_vtbls_init.  General cleanup.  Use
    expand_direct_vtbls_init to do hard work.  Ensures that _all_ vtable
    pointers from virtual bases are set up.
    * search.c (bfs_unmark_finished_struct, unmark_finished_struct):
    Removed.

    * *.[chy]: Remove support for VTABLE_USES_MASK.

Tue Apr 19 12:51:59 1994  Jason Merrill  ([e-mail])

    * cvt.c (convert_to_reference): Use NOP_EXPRs to switch between
    reference and pointer types instead of bashing the types directly.

    * call.c (build_overload_call_real): Use the TREE_CODE to determine
    whether the function is overloaded or not, rather than
    TREE_OVERLOADED.
    * *: Remove all uses of TREE_OVERLOADED.

    fields when -ansi or -pedantic.

Tue Apr 19 12:42:42 1994  Doug Evans  ([e-mail])

    their base classes.
    * parse.y (template_instantiate_once): Unset TYPE_BEING_DEFINED
    before we get to left_curly.
    * pt.c (instantiate_class_template): Set TYPE_BEING_DEFINED.

    * error.c (dump_decl): If it's a typedef, print out the name of the
    decl, not just the underlying type.

    * decl.c (pushdecl): If the old duplicate decl was a TYPE_DECL,
    update the IDENTIFIER_TYPE_VALUE of its name.

    * decl2.c (finish_file): When processing the initializer for a
    static member, pretend that the dummy function is a member of the
    same class.

Fri Apr 15 15:56:35 1994  Kung Hsu  ([e-mail])

    * class.c (build_vtable_entry): revert Apr 4 change.

Fri Apr 15 13:49:33 1994  Jason Merrill  ([e-mail])

    * typeck.c (build_conditional_expr): Pedwarn on pointer/integer
    mismatch, and don't pedwarn on 0/function pointer mismatch.

    * typeck2.c (digest_init): Lose code for special handling of unions.
    (process_init_constructor): Since they're handled just fine here.
    Pedwarn on excess elements.

    * decl2.c (grokfield): Complain about local class method declaration
    without definition.

Fri Apr 15 13:19:40 1994  Per Bothner  ([e-mail])

    * method.c (emit_thunk):  Add extern declaration for
    current_call_is_indirect (needed for hppa).

    Improve local class support; allow classes in different blocks to
    have the same name.
    * decl.c (pushtag): Support local classes better.
    (pushdecl_nonclass_level): New function for pushing mangled decls of
    nested types into the appropriate scope.
    (xref_defn_tag): Use pushdecl_nonclass_level instead of
    pushdecl_top_level.

    class methods.
    * method.c (do_inline_function_hair): Ditto.

    * class.c (finish_struct): It is legal for a class with no
    constructors to have nonstatic const and reference members.

Thu Apr 14 07:15:11 1994  Brendan Kehoe  ([e-mail])

    * decl.c (push_overloaded_decl): Avoid giving errors about
    built-ins, since duplicate_decls will have given warnings/errors
    for them.

Thu Apr 14 03:45:12 1994  Jason Merrill  ([e-mail])

    * cvt.c (convert_to_reference): Warn about casting pointer type to
    reference type when this is probably not what they wanted.

Wed Apr 13 13:12:35 1994  Per Bothner  ([e-mail])

    * decl.c (finish_decl):  Don't mindlessly set TREE_USED for
    static consts any more (toplev.c has now been modified to
    not emit warnings if they are unused).

Wed Apr 13 00:22:35 1994  Jason Merrill  ([e-mail])

    * decl.c (grok_op_properties): If op new/delete get here with
    METHOD_TYPEs, do a revert_static_member_fn.

    * cp-tree.h (IDENTIFIER_CLASS_TYPE_VALUE): Lose.
    * init.c (is_aggr_typedef): Don't look at
    IDENTIFIER_CLASS_TYPE_VALUE.

    (get_type_value): Ditto.
    * call.c (build_scoped_method_call): Don't rely on overloaded
    template names having IDENTIFIER_CLASS_VALUE set.

    * parse.y (component_decl_1, fn.def2): Revert rules for
    constructors.
    (component_decl_1, fn.def2): Use $1 instead of $$, since $$ is being
    clobbered.

    * decl.c (start_function): Only warn about `void main()' if pedantic
    || warn_return_type.

Tue Apr 12 02:14:17 1994  Jason Merrill  ([e-mail])

    Clean up overloading of the template name.
    * class.c (pushclass): overload the template name whenever pushing
    into the scope of a template class, not just if it is
    uninstantiated.
    (popclass): Correspondingly.
    * search.c (push_class_decls): Don't overload_template_name.
    * pt.c (overload_template_name): Don't set IDENTIFIER_LOCAL_VALUE or

    (build_opfncall): Ditto.
    * lex.c (init_lex): Set up values of ansi_opname and opname_tab for
    vec new/delete.  vec new uses "__vn", and vec delete uses "__vd".
    * init.c (init_init_processing): Set up BIVN and BIVD.
    (do_friend): Don't clean up after mistaken setting of TREE_GETS_NEW,
    since it doesn't happen any more.
    (build_new): Support vec new.  Always call something.
    (build_x_delete): Support vec delete.
    (build_vec_delete): Lose dtor_dummy argument, add use_global_delete,
    and pass it to build_x_delete.
    * decl2.c (delete_sanity): Don't change behavior by whether or not
    the type has a destructor.  Pass use_global_delete to
    build_vec_delete.
    (coerce_delete_type): Make sure that the type returned has a first
    argument of ptr_type_node.
    * decl.c (init_decl_processing): Also declare the global vec
    new/delete.
    (grokdeclarator): Also force vec new/delete to be static.
    (grok_op_properties): Note presence of vec new/delete, and play with
    their args.  If vec delete takes the optional size_t argument, set
    TYPE_VEC_DELETE_TAKES_SIZE.
    * cp-tree.h (TYPE_GETS_{REG,VEC}_DELETE): New macros to simplify
    checking for one delete or the other.
    (lang_type): gets_new and gets_delete are now two bits long.  The
    low bit is for the non-array version.  Lose gets_placed_new.
    (TYPE_VEC_DELETE_TAKES_SIZE): New macro indicating that the vec
    delete defined by this class wants to know how much space it is
    deleting.
    (TYPE_VEC_NEW_USES_COOKIE): New macro to indicate when vec new must
    add a header containing the number of elements in the vector; i.e.
    when the elements need to be destroyed or vec delete wants to know
    the size.
    * class.c (finish_struct_methods): Also check for overloading vec
    delete.
    * call.c (build_method_call): Also delete second argument for vec
    delete.

    * decl.c (grokdeclarator): Correct complaints again.
    (grokdeclarator): Fix segfault on null declarator.
    (decls_match): Also accept redeclaration with no arguments if both
    declarations were in C context.  Bash TREE_TYPE (newdecl) here.
    (duplicate_decls): Instead of here.

    * parse.y (nested_name_specifier_1): Lose rules for dealing with
    syntax errors nicely, since they break parsing of 'const i;'.

    * decl.c (lookup_name): if (got_scope == current_class_type)
    val = IDENTIFIER_CLASS_VALUE (name).

    * search.c (lookup_nested_tag): Look in enclosing classes, too.

    * spew.c (yylex): Only look one character ahead when checking for a
    SCOPE.

    * lex.c (check_newline): Read first nonwhite char before
    incrementing lineno.

    * decl.c (grokdeclarator): Don't claim that typedefs are variables
    in warning.

    * parse.y: Divide up uses of unqualified_id into
    notype_unqualified_id and unqualified_id, so that TYPENAME can be
    used as an identifier after an object.

    * class.c (push_nested_class): Don't push into non-class scope.

    * decl.c (grokdeclarator): If an identifier could be a type
    conversion operator, but has no associated type, it's not a type
    conversion operator.

    * pt.c (unify): Check for equality of constants better.

    * decl.c (grokdeclarator): Don't complain about access decls.

Sun Apr 10 02:39:55 1994  Jason Merrill  ([e-mail])

    * decl.c (grokdeclarator): pedwarn about data definitions without
    types here.

    * parse.y (datadef): Don't pedwarn about decls without types here,
    since that is valid for functions.
    (fn.def2, component_decl): Support constructors with declmods again.
    (nomods_initdecls): For decls without any mods, so that we don't try
    to get declspecs from some arbitrary $0.

    * search.c (lookup_field): Use cp_error.

    * parse.y (nested_name_specifier_1): Don't check aggr/non-aggr type
    here; it breaks destructors for non-aggr types.

    * decl.c (lookup_name): Only look for TYPE_DECLs in base classes of
    a type being defined, like the comment says.
    If got_scope is not an aggregate, just return NULL_TREE.

    * pt.c (create_nested_upt): Kung's code for creating types nested
    within uninstantiated templates now lives here (it used to live in
    hack_more_ids).  It needs to be expanded.

    * parse.y: Stop calling see_typename so much.

    * decl.c (lookup_name): Deal with TTPs and UPTs.

    * lex.c (real_yylex): Don't set looking_for_typename just because we
    saw a 'new'.
    (dont_see_typename): #if 0 out.

    * spew.c (yylex): Increment looking_for_typename if the next
    character is SCOPE, rather than setting it to 1; this way, the value
    from seeing an aggr specifier will not be lost.  This kinda relies
    on looking_for_typename never being < 0, which is now true.

    * parse.y (nested_name_specifier_1): Accept TEMPLATE_TYPE_PARMs,
    too.
    (named_class_head_sans_basetype): Accept template types, too.  Oops.

Fri Apr  8 16:39:35 1994  Jason Merrill  ([e-mail])

    * decl2.c (reparse_decl_as_expr1): Handle SCOPE_REFs.

    * parse.y: Lose START_DECLARATOR.

    * search.c (lookup_nested_tag): New function to scan CLASSTYPE_TAGS
    for a class.

    * parse.y: Simplify fn.def2 and component_decl.  Support 'enum
    A::foo' syntax.  Catch invalid scopes better.

    * parse.y, lex.c: lose TYPENAME_COLON.

    * decl2.c (groktypefield): #if 0 out.

    * decl.c (lookup_name): If the type denoted by got_scope is
    currently being defined, look in CLASSTYPE_TAGS rather than FIELDS.

    * class.c (push_nested_class): Don't try to push into
    error_mark_node.

Fri Apr  8 07:26:36 1994  Brendan Kehoe  ([e-mail])

    * Makefile.in (stamp-parse): Update count of conflicts to 33.

Thu Apr  7 17:47:53 1994  Jason Merrill  ([e-mail])

    A saner implementation of nested types that treats template types
    no differently from non-template types.  There are still some
    shortcomings of our system; most notably, it is difficult to look
    for a nested type that is hidden by another name, because of the way
    we keep track of hidden types.  But this shouldn't be a problem for
    just about anyone.  Perhaps lookup_field should be fixed up a bit.

    * spew.c: Moved handling of nested types/scoping from the lexer
    into the parser.  Removed variable template_type_seen_before_scope.
    Removed functions frob_identifier, hack_more_ids, and various cruft
    that was #if 0'd out in the past, reducing the size of the file from
    1146 lines to 450 lines.  We can't quite do away with spew.c yet,
    though; we still need it for do_aggr () and checking for SCOPE after
    the current identifier.  And setting lastiddecl.

    * parse.y: Moved handling of nested types/scoping from the lexer
    into the parser, using a new global variable `got_scope'.  Reduced
    the number of states by 53.  Implemented all uses of explicit global
    scope.  Removed terminals SCOPED_TYPENAME and SCOPED_NAME.  Removed
    nonterminals tmpl.1, scoped_base_class, id_scope, typename_scope,
    scoped_typename.  Added nonterminals nested_type,
    qualified_type_name, complete_type_name, qualified_id, ptr_to_mem,
    nested_name_specifier, global_scope, overqualified_id, type_name.
    Changed many others.  Added 9 new reduce/reduce conflicts, which are
    nested type parallels of 9 that were already in the grammar for
    non-nested types.  Eight of the now 33 conflicts should be removed
    in the process of resolving the late binding between variable and
    function decls.

    * gxxint.texi (Parser): Update.

    * cp-tree.h (IS_AGGR_TYPE_CODE): Add UNINSTANTIATED_P_TYPE.

    * lex.h: Add decl for got_scope.

    * lex.c (see_typename): Claim to be the lexer when calling
    lookup_name.

    * decl.c (lookup_name): When called from the lexer, look at
    got_scope and looking_at_typename; otherwise don't.

Thu Apr  7 22:05:47 1994  Mike Stump  ([e-mail])

    31th Cygnus<->FSF merge.

Thu Apr  7 17:47:53 1994  Jason Merrill  ([e-mail])

    * decl2.c (mark_vtable_entries): Call this to mark all the
    entries in the vtable addressable.
    (finish_decl_parsing): Handle SCOPE_REFs.

    * decl.c (decls_match): Always call compparms with strict == 1.
    Handle the special case of C function redecl here.
    (duplicate_decls): Only keep the old type if the new decl takes no
    arguments.

    * typeck.c (compparms): Also allow t1 to be ... if strict == 0.

Thu Apr  7 16:17:50 1994  Mike Stump  ([e-mail])

    * class.c (build_vtable_entry): Fix breakage introduced Apr 5
    17:48:41.

Wed Apr  6 16:05:10 1994  Per Bothner  ([e-mail])

    * init.c (build_virtual_init), search.c (build_vbase_vtables_init),
    ch-tree.h:  Every place these functions were called, the result was
    immediately passed to expand_expr_stmt.  Reduce redundancy by
    calling expand_expr_init *inside* these functions.  These
    makes for a simpler interface, and we don't have to build
    compound expressions.  Hence, rename these function to:
    expand_virtual_init and expand_vbase_vtables_init respectively.
    * init.c, decl.c:  Change callers of these functions.
    * init.c, cp-tree.h (expand_virtual_init):  Make static.

    * decl2.c (finish_file): Check TREE_PUBLIC||TREE_ADDRESSABLE
    rather than DECL_SAVED_INSNS before emitting inlines.

Wed Apr  6 13:06:39 1994  Jason Merrill  ([e-mail])

    * spew.c (init_spew): #if 0 out stuff used by arbitrate_lookup.

    * decl.c (duplicate_decls): If this is a new declaration of an
    extern "C" function, keep the type (for the argtypes).
    (redeclaration_error_message): Don't check DECL_LANGUAGE here.
    (decls_match): Call compparms with a value of strict dependent on
    the value of strict_prototypes for DECL_LANGUAGE (oldecl).

    * typeck.c (compparms): ... is only equivalent to non-promoting
    parms if we're not being strict.

    * parse.y (empty_parms): Don't check flag_ansi || pedantic here.

    * decl.c (init_decl_processing): if (flag_ansi || pedantic)
    strict_prototypes_lang_c = strict_prototypes_lang_cplusplus;

    * decl2.c (grok_function_init): Don't set DECL_INITIAL on pure
    virtuals.

Tue Apr  5 17:48:41 1994  Per Bothner  ([e-mail])

    Support for implementing vtables with thunks.
    * tree.def (THUNK_DECL):  New TREE_CODE.
    * cp-tree.h (FNADDR_FROM_VTABLE_ENTRY), tree.c
    (fnaddr_from_vtable_entry):  Handle flag_vtable_thunks case.
    * cp-tree.h (memptr_type):  New variable.
    * class.c (build_vtable_entry):  Build thunk if necessary.
    * class.c (build_vfn_ref):  If using thunks, don't need
    to add delta field from vtable (there is none!).
    * decl.c: Add memptr_type as well as vtable_entry_type.
    If using thunks, the latter is just ptr_type_node.
    * gc.c, typeck.c:  Use memptr_typeChange, not vtable_entry_type.
    * decl2.c (finish_vtable_vardecl):  Handle thunks.
    * expr.c (cplus_expand_expr):  Support THUNK_DECL.

    * decl.c (grokdeclarator):  Set DECL_THIS_EXTERN if "extern".
    * decl.c (start_function):  Set current_extern_inline based on
    DECL_THIS_EXTERN, not TREE_PUBLIC.
    * decl.c (finish_function):  Call mark_inline_for_output if needed,

    Improve intelligence about when to emit inlines.
    * cp-tree.h (lang_decl_flags):  New field saved_inline.
    * cp-tree.h (DECL_SAVED_INLINE):  New macro.
    * class.c (add_virtual_function):  Don't set TREE_ADDRESSABLE.
    * decl.h, decl.c (pending_addressable_inlines):  Removed.
    * decl2.c (pending_addressable_inlines):  Renamed to saved_inlines.
    * decl2.c (mark_inline_for_output):  Do nothing if
    DECL_SAVED_INLINE;  otherwise set it (and add to saved_inlines list).
    * decl2.c (finish_vtable_vardecl):  SET_CLASSTYPE_INTERFACE_KNOWN
    and set CLASSTYPE_INTERFACE_ONLY if there is a non-inline virtual.
    * decl2.c (finish_file):  Writing out inlines later, so we can
    also handle the ones needed for vtbales.
    * decl2.c (write_vtable_entries, finish_vtable_typedecl):  Removed.

    * cp-tree.h, class.c, decl2.c, search.c:  Remove -fvtable-hack
    and flag_vtable_hack.      Use -fvtable-thunks and flag_vtable_thunks
    instead.  (The rationale is that these optimizations both break binary
    compatibility, but should become the default in a future release.)

Wed Apr  6 10:53:56 1994  Mike Stump  ([e-mail])

    * class.c (modify_vtable_entries): Never reset the DECL_CONTEXT
    of a fndecl, as we might not be from that vfield.

Tue Apr  5 17:43:35 1994  Kung Hsu  ([e-mail])

    * class.c (add_virtual_function): fix bug for pure virtual, so
    that DECL_VINDEX of the dummy decl copied won't be error.
    (see also Apr 4 change)

Tue Apr  5 17:23:45 1994  Per Bothner  ([e-mail])

    * typeck.c (c_expand_return):  Before checking that we're not
    returning the address of a local, make sure it's a VAR_DECL.
    (And don't worry about it being a TREE_LIST.)

Tue Apr  5 13:26:42 1994  Jason Merrill  ([e-mail])

    (absdcl1): Ditto.

Sat Mar 19 01:05:17 1994  Jason Merrill  ([e-mail])

    (direct_declarator): New nonterminal for
    direct_after_type_declarator and direct_notype_declarator.

Thu Mar 17 17:30:01 1994  Jason Merrill  ([e-mail])

    ANSI unqualified-id nonterminal except TYPENAMEs.

    `int (*a)'.
    (primary): Use notype_unqualified_id.
    (decl): Add typespec initdecls ';' and typespec declarator ';'

    an expr_or_declarator.
    (complex_direct_notype_declarator): A direct_notype_declarator that
    doesn't conflict with expr_or_declarator.  Use
    notype_unqualified_id.  Remove id_scope see_typename TYPENAME rule.
    (functional_cast): New nonterminal, for the three functional cast
    rules.  So that they can be moved after
    complex_direct_notype_declarator.
    (see_typename): Don't accept type_quals any more.

    * decl2.c (reparse_decl_as_expr): New function to deal with parse
    nodes for code like `int (*a)++;'.
    (reparse_decl_as_expr1): Recursive subroutine of the above.
    (finish_decl_parsing): New function to deal with parse nodes for
    code like `int (*a);'.  See the difference?

Wed Mar 16 17:43:07 1994  Jason Merrill  ([e-mail])

    * parse.y (direct_notype_declarator): Add PTYPENAME rule, remove

    * search.c (get_vbase_types): Accept binfo argument, too.

Tue Mar 15 19:22:05 1994  Kung Hsu  ([e-mail])

    * decl.c (complete_array_type): complete TYPE_DOMAIN of the

    * error.c (dump_expr): Support member functions (which show up as
    OFFSET_REFs).

    (dont_see_typename): Comment out.
    (bad_parm): Break out abs_or_notype_decl into two rules.

    * parse.y (unary_expr): Use 'typename' in 'new' rules, rather
    than expanding it inline.
    (typename): Expand empty option of (former) absdcl inline.
    (abs_or_notype_decl): Ditto.
    (absdcl): Lose empty rule.
    (conversion_declarator): New nonterminal for 'typename' of 'operator
    typename'.
    (operator_name): Use it instead of absdcl.

    * parse.y: Add precedence declarations for SCOPED_TYPENAME,
    TYPEOF, and SIGOF.
    (typed_declspecs): Accept typed_typespecs, rather than typespec
    directly.  Add rules with reserved_typespecquals.
    (reserved_declspecs): Don't accept typespecqual_reserved at the
    beginning of the list.  The typed_declspecs rule will deal with this
    omission.
    (declmods): Accept nonempty_type_quals, rather than TYPE_QUAL
    directly.

    * parse.y (direct_notype_declarator,
    direct_after_type_declarator, direct_abstract_declarator): Split up
    the declarator1 nonterminals to match the draft standard and avoid
    ambiguities.
    (new_type_id, new_declarator, direct_new_declarator,
    new_member_declarator): New nonterminals to implement the subset of
    'typename' allowed in new expressions.

    previously duplicated in get_decl_list and list_hash_lookup_or_cons.
    (get_decl_list): Use it.
    (list_hash_lookup_or_cons): Ditto.

    * parse.y (typed_declspecs, declmods): It's not necessary to hash
    the declspecs on class_obstack, so don't.  This way typed_typespecs
    can reduce to typed_declspecs.

Wed Mar  2 14:29:18 1994  Jason Merrill ([e-mail])

    * cvt.c (build_up_reference): If we aren't checking visibility,
    also allow base->derived conversions.

    * decl2.c (finish_vtable_vardecl):  If flag_vtable_hack,
    and  !CLASSTYPE_INTERFACE_KNOWN, try to use the presence of
    a non-inline virtual function to control emitting of vtables.
    * class.c (finish_struct):  Build CLASSTYPE_METHODS list.
    * search.c (build_vbase_vtables_init):  Don't assemble_external
    (yet) if flag_vtable_hack.

Mon Feb 28 14:54:13 1994  Jason Merrill  ([e-mail])

    * parse.y (component_decl): Don't include "typed_declspecs
    declarator ';'" speedup, since it breaks enums.

    * class.c (finish_struct):  Minor optimization for building
    fn_fields list.

    * decl.c (start_function): Fix detection of function overloading.

Thu Feb 24 22:26:19 1994  Mike Stump  ([e-mail])

    * lex.c (check_newline): #pragma interface can take a string
    argument, just like #pragma implementation.  #pragma implementation
    checks for garbage on the line, line #pragma interface does.  Main
    input files do not auto implement like named files, #pragma
    implementation must be used explicitly.

Thu Feb 24 17:09:01 1994  Jason Merrill  ([e-mail])

    * parse.y (components): Handle list of one again.
    (notype_components): Ditto.

    * Makefile.in (stamp-parse): Update expected conflict count.

    * parse.y (various): Replace "declmods declarator" with "declmods
    notype_declarator".  The comment saying that "declmods declarator ';'"
    corresponds to "int i;" was wrong; it corresponds to "const i;".
    (component_decl): Add "typed_declspecs declarator ';'" rule; this
    *does* correspond to "int i;".  Change "declmods components" to
    "declmods notype_components".
    (components): Don't deal with a list of one anymore.
    (notype_components): New nonterminal, corresponds to notype_declarator.
    ({after_,no}type_component_decl{,0}): More new nonterminals.

    nonterminal so that we can stick %prec EMPTY on it.

    Add more %prec EMPTY's to eliminate remaining shift/reduce
    conflicts.

    (after_type_declarator): Add maybe_raises to fndecl rules.
    (after_type_declarator_no_typename): Remove.
    For correctness.

    Document remaining reduce/reduce conflicts.

Tue Feb 22 12:10:32 1994  Jason Merrill  ([e-mail])

    remove.

Sat Feb 19 01:27:14 1994  Jason Merrill  ([e-mail])

    * parse.y: Eliminate 20 shift/reduce conflicts.

Fri Feb 18 11:49:42 1994  Jason Merrill  ([e-mail])

    * pt.c (type_unification): Add subr argument; if set, it means
    that we are calling ourselves recursively, so a partial match is OK.
    (unify): Support pointers to methods and functions.
    (tsubst): Support method pointers.
    * decl.c (build_ptrmemfunc_type): No longer static, so that
    tsubst can get at it.

    type_unification.
    * pt.c (do_function_instantiation): Ditto.
    * class.c (instantiate_type): Ditto.

    * search.c (get_base_distance): If BINFO is a binfo, use it and
    don't mess with its BINFO_INHERITANCE_CHAIN.

    * cvt.c (convert_to_reference): Fix temporary generation.
    If ambiguous, return error_mark_node.

    * init.c (build_new): Put back some necessary code.

Thu Feb 17 15:39:47 1994  Jason Merrill  ([e-mail])

    * init.c (build_new): Deal with array types properly.

    * search.c (get_binfo): Become a shell for get_base_distance.
    (get_binfo_recursive): Lose.
    (get_base_distance_recursive): Find the path to the via_virtual base
    that provides the most access.
    (get_base_distance): Ditto.

    * parse.y (explicit_instantiation): Syntax is 'template class
    A<int>', not 'template A<int>'.

    * typeck.c (convert_for_initialization): Remove bogus warning.

    * parse.y (datadef): Revert patch of Oct 27.

Thu Feb 17 15:12:29 1994  Per Bothner  ([e-mail])

    goes onto the same obstack as its target type.

Wed Feb 16 00:34:46 1994  Jason Merrill  ([e-mail])

    * cvt.c (convert_to_reference): If converting via constructor
    on local level, go back to build_cplus_new approach.

    * tree.c (build_cplus_new): If with_cleanup_p, set cleanup slot
    to error_mark_node to prevent expand_expr from building a cleanup
    for this variable.

    * lex.c (default_assign_ref_body): Return *this from the memcpy
    version, too.

    * decl.c (grok_reference_init): Just return if called with
    error_mark_node, don't worry about initializing non-const reference
    with temporary.

    * cvt.c (convert_to_reference): Do the right thing for
    non-aggregate reference conversions, pedwarn when generating a
    non-const reference to a temporary.

    * class.c (finish_struct): TYPE_HAS_COMPLEX_{INIT,ASSIGN}_REF and
    TYPE_NEEDS_CONSTRUCTING all depend on TYPE_USES_VIRTUAL_BASECLASSES
    again.

Tue Feb 15 19:47:19 1994  Jason Merrill  ([e-mail])

    * decl.c (grok_reference_init): Pawn off a lot of the work on
    convert_to_reference.  Generally do the right thing.

    * cvt.c (convert_to_reference): Conform to the initial comment;
    i.e. don't create temps if decl != error_mark_node.  Handle
    cleanups better for temps that do get created.  Don't pretend
    that we can use an 'A' to initialize a 'const double &' just by
    tacking on a NOP_EXPR.  Support LOOKUP_SPECULATIVELY.

    * call.c (build_method_call): Set TREE_HAS_CONSTRUCTOR on
    constructor calls.

Mon Feb 14 14:50:17 1994  Jason Merrill  ([e-mail])

    * decl.c (grok_reference_init): Make a temporary for initializing
    const reference from constant expression.

Mon Feb 14 11:31:31 1994  Per Bothner  ([e-mail])

    * cp-tree.h, decl.c (set_identifier_local_value):  Deleted function.
    * decl.c (pushdecl):  Define decl in correct binding_level
    (which isn't always the inner_binding_level).

    * cvt.c (build_up_reference):  Don't ever call expand_aggr_init.
    It's ugly, and I don't think it's the right thing to do.

    * cp-tree.h, class.c, decl.c, decl2.c, sp/search.c:
    Remove NEW_CLASS_SCOPING, assuming it is always 1.
    * decl.c (pop_decl_level):  Removed; manually inlined.

Sun Feb 13 19:04:56 1994  Jason Merrill  ([e-mail])

    * class.h (candidate): Add basetypes field.

        with destructor names when either NO_DOLLAR_IN_LABEL or
        NO_DOT_IN_LABEL are not defined.

        Now `template <class T, T f(T&), const T*> class A {...}' works.

        with actual types in complex type as well.
        (coerce_template_parms): update the grok_template_type ()

    default arguments.

    initialize a type that needs constructing with a CONSTRUCTOR.

    * init.c (expand_aggr_init_1, CONSTRUCTOR case): If
    store_init_value fails, build and expand an INIT_EXPR.  If
    store_init_value succeeds, call expand_decl_init.

    * class.c (build_vbase_path): Use complete_type_p instead of
    resolves_to_fixed_type_p to determine if the virtual bases are in
    their right place for the type of expr.  Cures problem of thinking a
    virtual base class is one place, when it is in fact someplace else.

Fri Feb 11 00:26:46 1994  Mike Stump  ([e-mail])

    * init.c (resolve_offset_ref): Make sure we first convert to
    intermediate type, if given, when dealing with members off `this'.
    Solves an incorrrect `type `foo' is not a base type for type
    `multiple'' when it is infact, a base type.

Thu Feb 10 21:49:35 1994  Mike Stump  ([e-mail])

    * class.c (modify_other_vtable_entries): Use get_binfo, instead
    of binfo_value.  Solves problem with compiler giving a `base class
    `B' ambiguous in binfo_value (compiler error)' on complex MI
    herarchies, when a virtual function is first defied in a virtual
    base class.

Thu Feb 10 17:19:32 1994  Mike Stump  ([e-mail])

    * class.c (build_vbase_path): Don't complain about ambiguous

    * init.c (build_new): Deal with `new double (1)'.

    * class.c (finish_struct): TYPE_HAS_COMPLEX_*_REF are supersets of
    TYPE_HAS_REAL_*_REF, but TYPE_HAS_COMPLEX_INIT_REF is independent of
    TYPE_NEEDS_CONSTRUCTING.

    * decl.c (duplicate_decls): Propagate access decls.

    * typeck2.c (process_init_constructor): Accept empty_init_node
    for initializing unions.

    * class.c, lex.c, cp-tree.h: Use
    TYPE_HAS_COMPLEX_ASSIGN_REF where TYPE_HAS_REAL_ASSIGN_REF was used
    before, use TYPE_HAS_COMPLEX_INIT_REF for TYPE_NEEDS_CONSTRUCTING in
    some places.

    * decl.c (finish_decl): Don't complain about uninitialized const

    (lang_decode_option): Set warn_return_type, not explicit_*, for

    * cp-method.c (build_opfncall): Don't count pointer to member

    * cp-tree.c (get_unique_fn): New function; returns FUNCTION_DECL
    if unambiguous, NULL_TREE otherwise.
    (get_first_fn): Returns the first appropriate FUNCTION_DECL.
    (is_overloaded_fn): Returns whether or not the passed tree is
    a function or list of functions.

    * cp-init.c (init_init_processing): use `get_first_fn' to find
    the FUNCTION_DEFN for new and delete.

    * cp-decl.c (push_overloaded_decl): Use new overloading strategy, cut
    code size in half (I spit on special cases).
