3 * typemanager.cs (InitCoreTypes): Init also value_type
6 * expression.cs (Cast::Resolve): First resolve the child expression.
8 (LValue): Add new method AddressOf to be used by
11 Change the argument of Store to take an EmitContext instead of an
12 ILGenerator, because things like FieldExpr need to be able to call
13 their children expression to generate the instance code.
15 (Expression::Error, Expression::Warning): Sugar functions for
18 (Expression::MemberLookup): Accept a TypeContainer instead of a
19 Report as the first argument.
21 (Expression::ResolvePrimary): Killed. I still want to improve
22 this as currently the code is just not right.
24 (Expression::ResolveMemberAccess): Simplify, but it is still
27 (Unary::Resolve): Catch errors in AddressOf operators.
29 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
30 index to a byte for the short-version, or the compiler will choose
31 the wrong Emit call, which generates the wrong data.
33 (ParameterReference::Emit, ::Store): same.
35 (FieldExpr::AddressOf): Implement.
37 * typemanager.cs: TypeManager: made public variable instead of

65 the work of all the checking.
66 (ConvertImplicit): Call CanConvert and only then create object if necessary.
67 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
69 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
70 that is the right way.
72 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
73 overloading resolution. Use everywhere instead of cutting and pasting code.
75 (Binary::ResolveOperator): Use MakeUnionSet.
77 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
78 we have to convert to bool types. Not complete yet.

88 implicit constant expression conversions.
90 (Expression::ConvertNumericExplicit): Finished.
92 (Invocation::Emit): If InstanceExpression is null, then it means
93 that we perform a call on this.
95 2001-09-26 Miguel de Icaza <miguel@ximian.com>
97 * expression.cs (Unary::Emit): Remove some dead code.
98 (Probe): Implement Resolve and Emit for `is'.
99 (Expression::ConvertImplicitRequired): Attempt to do constant
100 expression conversions here. Maybe should be moved to
101 ConvertImplicit, but I am not sure.
102 (Expression::ImplicitLongConstantConversionPossible,
103 Expression::ImplicitIntConstantConversionPossible): New functions
104 that tell whether is it possible to apply an implicit constant
105 expression conversion.

126 (Expression::InternalTypeConstructor): Used to invoke constructors
127 on internal types for default promotions.
129 (Unary::Emit): Implement special handling for the pre/post
130 increment/decrement for overloaded operators, as they need to have
131 the same semantics as the other operators.
133 (Binary::ResolveOperator): ditto.
134 (Invocation::ConversionExists): ditto.

154 expressions that can appear in statements, so that we can provide
155 an alternate path to generate expression that do not leave a value

159 whether a value is left on the stack or not. Every expression
160 after being emitted leaves a single value on the stack.

190 * assign.cs: track location.
191 (Resolve): Use implicit conversions on assignment.
193 * literal.cs: Oops. Not good, Emit of short access values should
194 pass (Bytes) or the wrong argument will be selected.
196 * expression.cs (Unary::Emit): Emit code for -expr.
198 (Unary::ResolveOperator): Handle `Substract' for non-constants
199 (substract from zero from the non-constants).

256 * typemanager.cs: declare and load enum_type, delegate_type and
259 * expression.cs (Expression::Emit): Now emit returns a value that
260 tells whether a value is left on the stack or not. This strategy

314 * expression.cs: Instead of having FIXMEs in the Resolve
315 functions, throw exceptions so it is obvious that we are facing a
318 * cs-parser.jay (invocation_expression): Pass Location information.
320 * codegen.cs (CodeGen::Save, CodeGen::CodeGen, CodeGen::Basename):
321 Use a basename for those routines because .NET does not like paths

359 (Binary::ResolveOperator): Re-write bits to quietly continue if no overloaded
360 operators are found instead of making noise ;-)
361 (Unary::ResolveOperator): New method to do precisely the same thing which
362 Binary::ResolveOperator does for Binary expressions.
363 (Unary.method, .Arguments): Add.
364 (Unary::OperName): Implement.
365 (Unary::ForceConversion): Copy and Paste !
367 * class.cs (Operator::Define): Fix a small bug for the case when we have
370 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
371 for the inbuilt operators. Only overloading works for now ;-)
373 2001-09-18 Miguel de Icaza <miguel@ximian.com>

389 (FieldExpr::Emit): Implement.
391 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
392 the last instruction contains a return opcode to avoid generating
393 the last `ret' instruction (this generates correct code, and it is
394 nice to pass the peverify output).
396 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
397 initializer for static and instance variables.
398 (Constructor::Emit): Allow initializer to be null in the case of
399 static constructors. Only emit initializer for instance
402 (TypeContainer::FindMembers): Return a null array if there are no
405 Also fix the code for the MemberTypes.Method branch, as it was not
406 scanning that for operators (or tried to access null variables before).

412 * driver.cs: Stop compilation if there are parse errors.
414 * cs-parser.jay (constructor_declaration): Provide default base

452 * expression.cs (Expression::OverloadResolve): Drop TypeContainer
455 (Expression::MemberLookup): Provide a version that allows to
456 specify the MemberTypes and BindingFlags.
458 * statement.cs (Block::GetVariableInfo): Forgot to recurse here,

469 deal with this by semantically definining it as if the user had
472 (TypeContainer::FindMembers): Removed ad-hoc hack to deal with
473 constructors as we now "emit" them at a higher level.
475 (TypeContainer::DefineDefaultConstructor): Used to define the

561 * modifiers.cs: Do not use `parent', instead use the real type
562 container to evaluate permission settings.

574 * driver.cs: Added --parse option that only parses its input files
577 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
578 incorrect. IsTopLevel is not used to tell whether an object is
579 root_types or not (that can be achieved by testing this ==
580 root_types). But to see if this is a top-level *class* (not
581 necessarly our "toplevel" container).
583 2001-09-14 Ravi Pratap <ravi@ximian.com>
585 * enum.cs (Enum::Define): Modify to call the Lookup method on the
586 parent instead of a direct call to GetType.
588 2001-09-14 Ravi Pratap <ravi@ximian.com>
590 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
591 Modifiers.TypeAttr. This should just be a call to that method.

601 * modifiers.cs (FieldAttr): Re-write.

604 (TypeContainer::HaveStaticConstructor): New property to provide access
605 to precisely that info.
607 * modifiers.cs (MethodAttr): Re-write.
608 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
610 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
611 of top-level types as claimed.
613 2001-09-13 Miguel de Icaza <miguel@ximian.com>
615 * expression.cs (MemberLookup): Fruitless attempt to lookup
616 constructors. Maybe I need to emit default constructors? That
617 might be it (currently .NET emits this for me automatically).
618 (Invocation::OverloadResolve): Cope with Arguments == null.
619 (Invocation::EmitArguments): new function, shared by the new
621 (Invocation::Emit): Handle static and instance methods. Emit
622 proper call instruction for virtual or non-virtual invocations.

626 (MethodGroupExpr::InstanceExpression): used conforming to the spec
628 (FieldExpr::Resolve): Set type.
630 * support.cs: Handle empty arguments.

633 SimpleLookup): Auxiliary routines to help parse a qualifier
636 Update qualifier_identifier rule.
638 * codegen.cs: Removed debugging messages.
640 * class.cs: Make this a global thing, this acts just as a "key" to
641 objects that we might have around.
643 (Populate): Only initialize method_builders_to_methods once.
645 * expression.cs (PropertyExpr): Initialize type from the
648 * codegen.cs (EmitContext::EmitBoolExpression): Use propper
649 Resolve pattern. Attempt to implicitly convert value to boolean.
652 * expression.cs: Set the type for the int32/int32 argument case.
653 (Binary::ResolveOperator): Set the return type to boolean for
654 comparission operators
656 * typemanager.cs: Remove debugging print code.
658 (Invocation::Resolve): resolve type.
660 * class.cs: Allocate a MemberInfo of the correct size, as the code
661 elsewhere depends on the test to reflect the correct contents.
663 (Method::) Keep track of parameters, due to System.Reflection holes
665 (TypeContainer::Populate): Keep track of MethodBuilders to Method
668 (TypeContainer::FindMembers): Use ArrayList and then copy an array
669 of the exact size and return that.
671 (Class::LookupMethodByBuilder): New function that maps
672 MethodBuilders to its methods. Required to locate the information
673 on methods because System.Reflection bit us again.
675 * support.cs: New file, contains an interface ParameterData and
676 two implementations: ReflectionParameters and InternalParameters
677 used to access Parameter information. We will need to grow this
680 * expression.cs (Invocation::GetParameterData): implement a cache
681 and a wrapper around the ParameterData creation for methods.
682 (Invocation::OverloadResolve): Use new code.
684 2001-09-13 Ravi Pratap <ravi@ximian.com>
686 * class.cs (TypeContainer::EmitField): Remove and move into
687 (Field::Define): here and modify accordingly.
688 (Field.FieldBuilder): New member.
689 (TypeContainer::Populate): Update accordingly.
690 (TypeContainer::FindMembers): Implement.
692 2001-09-13 Miguel de Icaza <miguel@ximian.com>
694 * statement.cs: (VariableInfo::VariableType): New field to be
695 initialized with the full type once it is resolved.

1169 and re-write the code in the actions to extract the specific and
1170 general catch clauses by being a little smart ;-)
1172 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !

1231 instead of ignoring the rank_specifiers.
1232 (expression_list): Implement to collect the expressions

1268 generation from working. Also add some temporary debugging
1271 2001-08-24 Miguel de Icaza <miguel@ximian.com>
1273 * codegen.cs: Lots of code generation pieces. This is only the
1274 beginning, will continue tomorrow with more touches of polish. We

1282 emission to keep a context. Most of the code generation will be

1305 move from Properties to public readonly fields.

1307 function, and implements a cache that will be useful later when I
1308 do error checking and the semantic analysis on the methods is
1310 (Constructor::GetCallingConvention): Renamed from CallingConvetion
1311 and made a method, optional argument tells whether this is a class
1312 or a structure to apply the `has-this' bit.

1315 (Method::Define): Defines the type, a second pass is performed
1316 later to populate the methods.

1334 (Constructor::ParameterTypes): Returns the constructor parameter
1337 (TypeContainer::AddConstructor): Keep track of default constructor
1338 and the default static constructor.
1340 (Constructor::) Another class that starts using `public readonly'
1341 instead of properties.
1343 (Constructor::IsDefault): Whether this is a default constructor.
1345 (Field::) use readonly public fields instead of properties also.
1347 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
1348 track of static constructors; If none is used, turn on
1349 BeforeFieldInit in the TypeAttributes.
1351 * cs-parser.jay (opt_argument_list): now the return can be null
1352 for the cases where there are no arguments.
1354 (constructor_declarator): If there is no implicit `base' or
1355 `this', then invoke the default parent constructor.
1357 * modifiers.cs (MethodAttr): New static function maps a set of
1358 modifiers flags into a MethodAttributes enum
1359 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
1360 MethodAttr, TypeAttr to represent the various mappings where the
1362 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
1364 2001-08-19 Miguel de Icaza <miguel@ximian.com>
1366 * parameter.cs (GetParameterInfo): Fix bug where there would be no
1369 * interface.cs (PopulateIndexer): Implemented the code generator
1370 for interface indexers.
1372 2001-08-17 Miguel de Icaza <miguel@ximian.com>
1374 * interface.cs (InterfaceMemberBase): Now we track the new status
1377 (PopulateProperty): Implement property population. Woohoo! Got
1378 Methods and Properties going today.
1380 Removed all the properties for interfaces, and replaced them with
1381 `public readonly' fields.
1383 2001-08-16 Miguel de Icaza <miguel@ximian.com>
1385 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
1386 initialize their hashtables/arraylists only when they are needed
1387 instead of doing this always.
1389 * parameter.cs: Handle refs and out parameters.
1391 * cs-parser.jay: Use an ArrayList to construct the arguments
1392 instead of the ParameterCollection, and then cast that to a
1395 * parameter.cs: Drop the use of ParameterCollection and use
1396 instead arrays of Parameters.
1398 (GetParameterInfo): Use the Type, not the Name when resolving
1401 2001-08-13 Miguel de Icaza <miguel@ximian.com>
1403 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
1404 and instead use public readonly fields.
1406 * class.cs: Put back walking code for type containers.
1408 2001-08-11 Miguel de Icaza <miguel@ximian.com>
1410 * class.cs (MakeConstant): Code to define constants.
1412 * rootcontext.cs (LookupType): New function. Used to locate types
1415 2001-08-08 Miguel de Icaza <miguel@ximian.com>
1417 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
1418 this System.Reflection code is. Kudos to Microsoft
1420 * typemanager.cs: Implement a type cache and avoid loading all
1421 types at boot time. Wrap in LookupType the internals. This made
1422 the compiler so much faster. Wow. I rule!
1424 * driver.cs: Make sure we always load mscorlib first (for
1425 debugging purposes, nothing really important).
1427 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
1428 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
1430 * rootcontext.cs: Lookup types on their namespace; Lookup types
1431 on namespaces that have been imported using the `using' keyword.
1433 * class.cs (TypeContainer::TypeAttr): Virtualize.
1434 (Class::TypeAttr): Return attributes suitable for this bad boy.
1435 (Struct::TypeAttr): ditto.
1436 Handle nested classes.
1437 (TypeContainer::) Remove all the type visiting code, it is now
1438 replaced with the rootcontext.cs code
1440 * rootcontext.cs (GetClassBases): Added support for structs.
1442 2001-08-06 Miguel de Icaza <miguel@ximian.com>
1444 * interface.cs, statement.cs, class.cs, parameter.cs,
1445 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
1446 Drop use of TypeRefs, and use strings instead.
1448 2001-08-04 Miguel de Icaza <miguel@ximian.com>
1452 * class.cs (Struct::Struct): set the SEALED flags after
1453 checking the modifiers.
1454 (TypeContainer::TypeAttr): new property, returns the
1455 TypeAttributes for a class.
1457 * cs-parser.jay (type_list): Oops, list production was creating a
1458 new list of base types.
1460 * rootcontext.cs (StdLib): New property.
1461 (GetInterfaceTypeByName): returns an interface by type name, and
1462 encapsulates error handling here.
1463 (GetInterfaces): simplified.
1464 (ResolveTree): Encapsulated all the tree resolution here.
1465 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
1468 * driver.cs: Add support for --nostdlib, to avoid loading the
1470 (Main): Do not put tree resolution here.
1472 * rootcontext.cs: Beginning of the class resolution.
1474 2001-08-03 Miguel de Icaza <miguel@ximian.com>
1476 * rootcontext.cs: Provide better error reporting.
1478 * cs-parser.jay (interface_base): set our $$ to be interfaces.
1480 * rootcontext.cs (CreateInterface): Handle the case where there
1481 are no parent interfaces.
1483 (CloseTypes): Routine to flush types at the end.
1484 (CreateInterface): Track types.
1485 (GetInterfaces): Returns an array of Types from the list of
1488 * typemanager.c (AddUserType): Mechanism to track user types (puts
1489 the type on the global type hash, and allows us to close it at the
1492 2001-08-02 Miguel de Icaza <miguel@ximian.com>
1494 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
1495 RecordInterface instead.
1497 * cs-parser.jay: Updated to reflect changes above.
1499 * decl.cs (Definition): Keep track of the TypeBuilder type that
1500 represents this type here. Not sure we will use it in the long
1501 run, but wont hurt for now.
1503 * driver.cs: Smaller changes to accomodate the new code.
1505 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
1508 * rootcontext.cs (CreateInterface): New method, used to create
1509 the System.TypeBuilder type for interfaces.
1510 (ResolveInterfaces): new entry point to resolve the interface
1512 (CodeGen): Property, used to keep track of the code generator.
1514 2001-07-26 Miguel de Icaza <miguel@ximian.com>
1516 * cs-parser.jay: Add a second production for delegate_declaration
1519 (enum_body): Put an opt_comma here instead of putting it on
1520 enum_body or enum_member_declarations so we can handle trailing
1521 commas on enumeration members. Gets rid of a shift/reduce.
1523 (type_list): Need a COMMA in the middle.
1525 (indexer_declaration): Tell tokenizer to recognize get/set
1527 * Remove old targets.
1529 * Re-add the parser target.
1531 2001-07-13 Simon Cozens <simon@simon-cozens.org>
1533 * cs-parser.jay: Add precendence rules for a number of operators
1534 ot reduce the number of shift/reduce conflicts in the grammar.
1536 2001-07-17 Miguel de Icaza <miguel@ximian.com>
1538 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
1541 Get rid of old crufty code.
1543 * rootcontext.cs: Use this to keep track of the parsed
1544 representation and the defined types available to the program.
1546 * gen-treedump.cs: adjust for new convention.
1548 * type.cs: Split out the type manager, and the assembly builder
1551 * typemanager.cs: the type manager will live here now.
1553 * cil-codegen.cs: And the code generator here.
1555 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
1557 * makefile: Fixed up for easy making.
1559 2001-07-13 Simon Cozens <simon@simon-cozens.org>
1561 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
1564 (unary_expression): Expand pre_increment_expression and
1565 post_decrement_expression to reduce a shift/reduce.
1567 2001-07-11 Simon Cozens
1569 * cs-tokenizer.cs: Hex numbers should begin with a 0.
1571 Improve allow_keyword_as_indent name.
1573 2001-06-19 Miguel de Icaza <miguel@ximian.com>
1575 * Adjustments for Beta2.
1577 2001-06-13 Miguel de Icaza <miguel@ximian.com>
1579 * decl.cs: Added `Define' abstract method.
1580 (InTransit): new property, used to catch recursive definitions.
1582 * interface.cs: Implement `Define'.
1584 * modifiers.cs: Map Modifiers.constants to
1585 System.Reflection.TypeAttribute flags.
1587 * class.cs: Keep track of types and user-defined types.
1588 (BuilderInit): New method for creating an assembly
1589 (ResolveType): New function to launch the resolution process, only
1590 used by interfaces for now.
1592 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
1593 that are inserted into the name space.
1595 2001-06-08 Miguel de Icaza <miguel@ximian.com>
1597 * ARGH. I have screwed up my tree so many times due to the use of
1598 rsync rather than using CVS. Going to fix this at once.
1600 * driver.cs: Objetify driver. Load assemblies, use assemblies to
1603 2001-06-07 Miguel de Icaza <miguel@ximian.com>
1605 * Experiment successful: Use System.Type rather that our own
1608 2001-05-25 Miguel de Icaza <miguel@ximian.com>
1610 * cs-parser.jay: Removed nsAliases from here.
1612 Use new namespaces, handle `using XXX;'
1614 * namespace.cs: Reimplemented namespace handling, use a recursive
1615 definition of the class. Now we can keep track of using clauses
1616 and catch invalid using clauses.
1618 2001-05-24 Miguel de Icaza <miguel@ximian.com>
1620 * gen-treedump.cs: Adapted for all the renaming.
1622 * expression.cs (Expression): this class now has a Type property
1623 which returns an expression Type.
1625 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
1626 `Type', as this has a different meaning now in the base
1628 2001-05-22 Miguel de Icaza <miguel@ximian.com>
1630 * interface.cs, class.cs: Removed from all the sources the
1631 references to signature computation, as we can not do method
1632 signature computation during the parsing time, as we are not
1633 trying to solve at that point distinguishing:
1637 void a (NS.Blah x) {}
1640 Which depending on the context might be valid or not, as we do not
1641 know if Blah is the same thing as NS.Blah at that point.
1643 * Redid everything so the code uses TypeRefs now instead of
1644 Types. TypeRefs are just temporary type placeholders, that need
1645 to be resolved. They initially have a pointer to a string and the
1646 current scope in which they are used. This is used later by the
1647 compiler to resolve the reference to an actual Type.
1649 * DeclSpace is no longer a CIR.Type, and neither are
1650 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
1651 are all DeclSpaces, but no Types.
1653 * type.cs (TypeRefManager): This implements the TypeRef manager,
1654 which keeps track of all the types that need to be resolved after
1655 the parsing has finished.
1657 2001-05-13 Miguel de Icaza <miguel@ximian.com>
1659 * ARGH. We are going to have to store `foreach' as a class rather
1660 than resolving it, as we need to verify error 1579 after name
1661 resolution. *OR* we could keep a flag that says `This request to
1662 IEnumerator comes from a foreach statement' which we can then use
1663 to generate the error.
1665 2001-05-10 Miguel de Icaza <miguel@ximian.com>
1667 * class.cs (TypeContainer.AddMethod): we now add methods to the
1668 MethodGroup instead of the method hashtable.
1670 * expression.cs: Add MethodGroup abstraction, which gets us one
1671 step closer to the specification in the way we handle method
1674 * cs-parser.jay (primary_expression): qualified_identifier now
1675 tried to match up an identifier to a local variable reference or
1676 to a parameter reference.
1678 current_local_parameters is now a parser global variable that
1679 points to the current parameters for the block, used during name
1682 (property_declaration): Now creates an implicit `value' argument to
1685 2001-05-09 Miguel de Icaza <miguel@ximian.com>
1687 * parameter.cs: Do not use `param' arguments as part of the
1688 signature, per the spec.
1690 2001-05-08 Miguel de Icaza <miguel@ximian.com>
1692 * decl.cs: Base class for classes, structs and interfaces. This
1693 is the "Declaration Space"
1695 * cs-parser.jay: Use CheckDef for checking declaration errors
1696 instead of having one on each function.
1698 * class.cs: Factor out some code for handling error handling in
1699 accordance to the "Declarations" section in the "Basic Concepts"
1700 chapter in the ECMA C# spec.
1702 * interface.cs: Make all interface member classes derive from
1703 InterfaceMemberBase.
1705 2001-05-07 Miguel de Icaza <miguel@ximian.com>
1707 * Many things: all interfaces are parsed and generated in
1708 gen-treedump. Support for member variables, constructors,
1709 destructors, properties, constants is there.
1711 Beginning of the IL backend, but very little done, just there for
1714 2001-04-29 Miguel de Icaza <miguel@ximian.com>
1716 * cs-parser.jay: Fix labeled statement.
1718 * cs-tokenizer.cs (escape): Escape " and ' always.
1719 ref_line, ref_name: keep track of the line/filename as instructed
1720 by #line by the compiler.
1723 2001-04-27 Miguel de Icaza <miguel@ximian.com>
1725 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
1726 to match the values in System.CodeDOM.
1728 Divid renamed to Divide.
1730 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
1732 (Statements.set): remove.
1734 * System.CodeDOM/CodeCatchClause.cs: always have a valid
1737 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
1738 falseStatements always have valid values.
1740 * cs-parser.jay: Use System.CodeDOM now.
