Thu Aug 10 14:55:29 1995  Mike Stump  <mrs@cygnus.com>

	* except.c (expand_builtin_throw): Since we now use normal calling
	conventions for __throw, we have to remove the first layer off the

	solves a problem where cc1plus consumed exponential amounts of
	memory when -Wall was used.
	(expand_end_all_catch, expand_leftover_cleanups,
	expand_end_catch_block, expand_throw): Change all uses of
	throw_label to match new style.
	(do_unwind): Rename parameter to inner_throw_label, as it is now
	different from throw_label.  Also, assume that our caller will wrap
	the passed label with a LABEL_REF, if needed.
	(expand_builtin_throw): Make external, change so that the generated
	throw is now a real function.
	(expand_exception_blocks): Never generate throw code inside another
	function.

Fri Aug  4 12:20:02 1995  Mike Stump  <mrs@cygnus.com>

	* decl.c (grokdeclarator): Move checking of mutable const objects

	InsnSave.  Also, numerous speed improvements, and correctness
	improvements.  Double faulting in all situations should now be
	handled correctly.
	(expand_start_all_catch): Instead of having many terminate protected
	regions, just have one.
	(expand_start_catch_block): No longer have to protect

	expand_leftover_cleanups.
	(expand_end_all_catch): Use sequences instead of playing with insn
	links directly.
	(expand_exception_blocks): Likewise.  Also protect all catch clauses
	with one terminate region.

	pass unsaved SAVE_EXPRs to the backend.
	* tree.def (UNSAVE_EXPR): New tree code.
	* typeck.c (c_expand_return): Move goto/return code up inside
	conditional, as we don't always want to do this, we only want to do

	terms of text space and data space.  Now most of the savings that
	#pragma interface/implementation gives is automatic in a fair number
	of cases.

Sat Jan 28 04:57:33 1995  Jason Merrill  <jason@phydeaux.cygnus.com>

	(real_yylex): If we see an EOF in linemode, return END_OF_LINE.

	* 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.

	* decl.c (grokdeclarator): Only complain about initializing const
	fields when -ansi or -pedantic.

	Horrible kludge to prevent templates from being	instantiated by
	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  <kung@mexican.cygnus.com>

	* class.c (build_vtable_entry): revert Apr 4 change.
	* decl2.c (mark_vtable_entries): replace pure virtual function
	decl with abort's.

Fri Apr 15 13:49:33 1994  Jason Merrill  <jason@deneb.cygnus.com>

	* 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

	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. 
	(grokfndecl): Don't mess with IDENTIFIER_GLOBAL_VALUE for local
	class methods.
	* method.c (do_inline_function_hair): Likewise.

	* 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  <brendan@lisa.cygnus.com>

	* 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  <jason@deneb.cygnus.com>

	* 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  <bothner@kalessin.cygnus.com>

	* 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  <jason@deneb.cygnus.com>

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

	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  <jason@deneb.cygnus.com>

	Clean up overloading of the template name.

	* parse.y: Support vec new/delete.
	* method.c (build_decl_overload): Deal with vec new/delete.
	(build_opfncall): Likewise.
	* 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,

	build_vec_delete.

	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  <jason@deneb.cygnus.com>

	* 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  <jason@deneb.cygnus.com>

	* 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  <brendan@lisa.cygnus.com>

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

Thu Apr  7 17:47:53 1994  Jason Merrill  <jason@deneb.cygnus.com>

	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  <mrs@cygnus.com>

	31th Cygnus<->FSF merge.

Thu Apr  7 17:47:53 1994  Jason Merrill  <jason@deneb.cygnus.com>

	* 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  <mrs@cygnus.com>

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

Wed Apr  6 16:05:10 1994  Per Bothner  <bothner@kalessin.cygnus.com>

	* 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  <jason@deneb.cygnus.com>

	* 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.

	* 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  <mrs@cygnus.com>

	* 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  <kung@mexican.cygnus.com>

	* 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  <bothner@kalessin.cygnus.com>

	* 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  <jason@deneb.cygnus.com>

	* parse.y (YYDEBUG): Always define.
	* lex.c (YYDEBUG): Likewise.

Mon Apr  4 11:28:17 1994  Kung Hsu  <kung@mexican.cygnus.com>

	RTL point to abort, then put in virtual table.

	types.

	* tree.c (get_identifier_list): Only do the special handling
	thing if we're dealing with the main variant of the record type.

	* cvt.c (convert_to_reference): When converting between
	compatible reference types, use the pointer conversion machinery.
	Don't just blindly overwrite the old type.

Fri Apr  1 17:14:42 1994  Jason Merrill  <jason@deneb.cygnus.com>

	* call.c (build_method_call): When looking at global functions,
	be sure to use instance_ptr for the first argument, not some version
	of it that has been cast to a base class.  Also do this before
	comparing candidates.

Thu Mar 31 19:50:35 1994  Jason Merrill  <jason@deneb.cygnus.com>

	* call.c (build_method_call): Constructors can be called for

	* decl2.c (grok_func_init): do not abort as rtl for pur virtual

	global.

	* parse.y (extdefs): Don't pop everything if the current binding
	level is pseudo_global.

	These changes fix the compiler's handling of the functional cast/
	object declaration ambiguities in section 6.8 of the ARM.  They also
	add 11 reduce/reduce conflicts.  Sigh.

	* parse.y: Add precedence decls for OPERATOR and '~'.
	(notype_unqualified_id): New nonterminal, encompasses all of the
	ANSI unqualified-id nonterminal except TYPENAMEs.

	(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.

	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?

Thu Mar 17 12:16:10 1994  Mike Stump  <mrs@cygnus.com>

	These changes break binary compatibility in code with classes
	that use virtual bases.

	* search.c (dfs_get_vbase_types): Simplify and correct to make

	default index.

Wed Mar 16 17:43:07 1994  Jason Merrill  <jason@deneb.cygnus.com>

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

Tue Mar 15 19:22:05 1994  Kung Hsu  <kung@mexican.cygnus.com>

	* decl.c (complete_array_type): complete TYPE_DOMAIN of the 
	initializer also, because back-end requires it.

Tue Mar 15 15:33:31 1994  Jason Merrill  <jason@deneb.cygnus.com>

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

	checks for garbage on the line, line #pragma interface does.  Main

	* 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".

	conflicts.

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

	* decl.c (build_ptrmemfunc_type): Make sure that the pmf type
	goes onto the same obstack as its target type.

Wed Feb 16 00:34:46 1994  Jason Merrill  <jason@deneb.cygnus.com>

	* 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  <jason@deneb.cygnus.com>

	* 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.

	* decl.c (pushdecl):  Define decl in correct binding_level
	(which isn't always the inner_binding_level).

	Remove NEW_CLASS_SCOPING, assuming it is always 1.

	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

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

	* cp-decl.c (grokdeclarator): Use warn_return_type, not explicit_*.
	(finish_function): Also complain about no return in a non-void fn if
