3 * expression.cs (Probe::Emit): Is needs to do an isinst and then
6 (::CanConvert): Added Location argument. If the Location argument
7 is null (Location.Null), then we do not report errors. This is
8 used by the `probe' mechanism of the Explicit conversion. We do
9 not want to generate an error for something that the user
10 explicitly requested to be casted. But the pipeline for an
11 explicit cast first tests for potential implicit casts.
13 So for now, if the Location is null, it means `Probe only' to
14 avoid adding another argument. Might have to revise this
17 (ClassCast): New class used to type cast objects into arbitrary
18 classes (used in Explicit Reference Conversions).
20 Implement `as' as well.
22 Reverted all the patches from Ravi below: they were broken:
24 * The use of `level' as a mechanism to stop recursive
25 invocations is wrong. That was there just to catch the
26 bug with a strack trace but not as a way of addressing
29 To fix the problem we have to *understand* what is going
30 on and the interactions and come up with a plan, not
31 just get things going.
33 * The use of the type conversion cache that I proposed
34 last night had an open topic: How does this work across
35 protection domains. A user defined conversion might not
36 be public in the location where we are applying the
37 conversion, a different conversion might be selected
38 (ie, private A->B (better) but public B->A (worse),
39 inside A, A->B applies, but outside it, B->A will
42 * On top of that (ie, even if the above is solved),
43 conversions in a cache need to be abstract. Ie, `To
44 convert from an Int to a Short use an OpcodeCast', not
45 `To convert from an Int to a Short use the OpcodeCast on
46 the variable 5' (which is what this patch was doing).
48 2001-09-28 Ravi Pratap <ravi@ximian.com>
50 * expression.cs (Invocation::ConversionExists): Re-write to use
53 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
54 cache all conversions done, not just user-defined ones.
56 (Invocation::BetterConversion): The real culprit. Use ConversionExists
57 to determine if a conversion exists instead of acutually trying to
58 perform the conversion. It's faster too.
60 (Expression::ConvertExplicit): Modify to use ConversionExists to check
61 and only then attempt the implicit conversion.
63 2001-09-28 Ravi Pratap <ravi@ximian.com>
65 * expression.cs (ConvertImplicit): Use a cache for conversions
66 already found. Check level of recursion and bail out if necessary.

79 2001-09-27 Miguel de Icaza <miguel@ximian.com>
81 * codegen.cs: remove unnneded code

85 Fix the order in which implicit conversions are
88 The previous fixed dropped support for boxed conversions (adding a
89 test to the test suite now)
91 (UserImplicitCast::CanConvert): Remove test for source being null,
92 that code is broken. We should not feed a null to begin with, if
93 we do, then we should track the bug where the problem originates
94 and not try to cover it up here.
96 Return a resolved expression of type UserImplicitCast on success
97 rather than true/false. Ravi: this is what I was talking about,
98 the pattern is to use a static method as a "constructor" for
101 Also, do not create arguments until the very last minute,
102 otherwise we always create the arguments even for lookups that
103 will never be performed.
105 (UserImplicitCast::Resolve): Eliminate, objects of type
106 UserImplicitCast are born in a fully resolved state.
108 * typemanager.cs (InitCoreTypes): Init also value_type
111 * expression.cs (Cast::Resolve): First resolve the child expression.
113 (LValue): Add new method AddressOf to be used by
116 Change the argument of Store to take an EmitContext instead of an
117 ILGenerator, because things like FieldExpr need to be able to call
118 their children expression to generate the instance code.
120 (Expression::Error, Expression::Warning): Sugar functions for
123 (Expression::MemberLookup): Accept a TypeContainer instead of a
124 Report as the first argument.
126 (Expression::ResolvePrimary): Killed. I still want to improve
127 this as currently the code is just not right.
129 (Expression::ResolveMemberAccess): Simplify, but it is still
132 (Unary::Resolve): Catch errors in AddressOf operators.
134 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
135 index to a byte for the short-version, or the compiler will choose
136 the wrong Emit call, which generates the wrong data.
138 (ParameterReference::Emit, ::Store): same.
140 (FieldExpr::AddressOf): Implement.
142 * typemanager.cs: TypeManager: made public variable instead of
145 * driver.cs: document --fatal.
147 * report.cs (ErrorMessage, WarningMessage): new names for the old
148 Error and Warning classes.
150 * cs-parser.jay (member_access): Turn built-in access to types
151 into a normal simplename
153 2001-09-27 Ravi Pratap <ravi@ximian.com>
155 * expression.cs (Invocation::BetterConversion): Fix to cope
156 with q being null, since this was introducing a bug.

169 * expression.cs (UserImplicitCast::CanConvert): Static method to do
170 the work of all the checking.
171 (ConvertImplicit): Call CanConvert and only then create object if necessary.
172 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
174 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
175 that is the right way.
177 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
178 overloading resolution. Use everywhere instead of cutting and pasting code.
180 (Binary::ResolveOperator): Use MakeUnionSet.
182 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
183 we have to convert to bool types. Not complete yet.
185 2001-09-27 Miguel de Icaza <miguel@ximian.com>
187 * typemanager.cs (TypeManager::CSharpName): support ushort.
189 * expression.cs (Expression::TryImplicitIntConversion): Attempts
190 to provide an expression that performsn an implicit constant int
191 conversion (section 6.1.6).
192 (Expression::ConvertImplicitRequired): Reworked to include
193 implicit constant expression conversions.
195 (Expression::ConvertNumericExplicit): Finished.
197 (Invocation::Emit): If InstanceExpression is null, then it means
198 that we perform a call on this.
200 2001-09-26 Miguel de Icaza <miguel@ximian.com>
202 * expression.cs (Unary::Emit): Remove some dead code.
203 (Probe): Implement Resolve and Emit for `is'.
204 (Expression::ConvertImplicitRequired): Attempt to do constant
205 expression conversions here. Maybe should be moved to
206 ConvertImplicit, but I am not sure.
207 (Expression::ImplicitLongConstantConversionPossible,
208 Expression::ImplicitIntConstantConversionPossible): New functions
209 that tell whether is it possible to apply an implicit constant
210 expression conversion.

222 * class.cs (Operator): Update the operator names to reflect the
223 ones that the spec expects (as we are just stringizing the
226 * expression.cs (Unary::ResolveOperator): Fix bug: Use
227 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
228 previous usage did only work for our methods.
229 (Expression::ConvertImplicit): Handle decimal implicit numeric
231 (Expression::InternalTypeConstructor): Used to invoke constructors
232 on internal types for default promotions.
234 (Unary::Emit): Implement special handling for the pre/post
235 increment/decrement for overloaded operators, as they need to have
236 the same semantics as the other operators.
238 (Binary::ResolveOperator): ditto.
239 (Invocation::ConversionExists): ditto.

242 2001-09-26 Ravi Pratap <ravi@ximian.com>

259 expressions that can appear in statements, so that we can provide
260 an alternate path to generate expression that do not leave a value
263 (Expression::Emit, and all the derivatives): We no longer return
264 whether a value is left on the stack or not. Every expression
265 after being emitted leaves a single value on the stack.
267 * codegen.cs (EmitContext::EmitStatementExpression): Use the
268 facilties of ExpressionStatement if possible.
270 * cs-parser.jay: Update statement_expression.

295 * assign.cs: track location.
296 (Resolve): Use implicit conversions on assignment.
298 * literal.cs: Oops. Not good, Emit of short access values should
299 pass (Bytes) or the wrong argument will be selected.
301 * expression.cs (Unary::Emit): Emit code for -expr.
303 (Unary::ResolveOperator): Handle `Substract' for non-constants
304 (substract from zero from the non-constants).

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

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

438 * expression.cs (Unary::ResolveOperator): return the child
439 expression for expressions which are just +expr.

470 (Unary::ForceConversion): Copy and Paste !
472 * class.cs (Operator::Define): Fix a small bug for the case when we have
475 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
476 for the inbuilt operators. Only overloading works for now ;-)
478 2001-09-18 Miguel de Icaza <miguel@ximian.com>
480 * expression.cs (CheckedExpr::Resolve, CheckedExpr::Emit,
481 UnCheckedExpr::Resolve, UnCheckedExpr::Emit): Implement.

496 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
497 the last instruction contains a return opcode to avoid generating
498 the last `ret' instruction (this generates correct code, and it is
499 nice to pass the peverify output).
501 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
502 initializer for static and instance variables.
503 (Constructor::Emit): Allow initializer to be null in the case of
504 static constructors. Only emit initializer for instance
507 (TypeContainer::FindMembers): Return a null array if there are no

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

523 Catch the fact that constructors should not have parameters.
525 * class.cs: Do not emit parent class initializers for static

557 * expression.cs (Expression::OverloadResolve): Drop TypeContainer
560 (Expression::MemberLookup): Provide a version that allows to
561 specify the MemberTypes and BindingFlags.

567 Beforefieldinit as it was buggy.
569 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200
572 * class.cs (Constructor::Emit): Only emit if block is not null.
573 (TypeContainer::EmitDefaultConstructor): Removed routine, now we
574 deal with this by semantically definining it as if the user had
577 (TypeContainer::FindMembers): Removed ad-hoc hack to deal with
578 constructors as we now "emit" them at a higher level.
580 (TypeContainer::DefineDefaultConstructor): Used to define the
581 default constructors if none was provided.
583 (ConstructorInitializer): Add methods Resolve and Emit.

623 * rootcontext.cs: Fix bug: tree.Namespaces might be null.
625 2001-09-16 Ravi Pratap <ravi@ximian.com>
627 * class.cs (EmitStaticFieldInitializers, EmitFieldInitializers): Make public.
628 (TypeContainer::EmitConstructor): Remove and move code into Contructor::Emit.
629 (Constructor::Emit): Implement.
630 (EmitStaticFieldInitializers, EmitFieldInitializers): Ensure we return immediately
631 if we have no work to do.
632 (TypeContainer::Emit): Pass in TypeContainer as argument to the constructor's
635 * interface.cs (Interface::InterfaceAttr): Re-write to be more correct and complete.
636 (Interface::IsTopLevel): Add. Same as TypeContainer::IsTopLevel.

653 2001-09-14 Miguel de Icaza <miguel@ximian.com>
655 * class.cs (TypeContainer::FindMembers): Add support for
657 (MethodCore): New class that encapsulates both the shared aspects
658 of a Constructor and a Method.
659 (Method, Constructor): Factored pieces into MethodCore.

662 Load System assembly as well as part of the standard library.
664 * report.cs: Allow throwing exceptions on errors for debugging.
666 * modifiers.cs: Do not use `parent', instead use the real type
667 container to evaluate permission settings.

670 have to cope with the
672 2001-09-14 Ravi Pratap <ravi@ximian.com>
674 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to
675 FamORAssem, not FamANDAssem.

679 * driver.cs: Added --parse option that only parses its input files
682 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
683 incorrect. IsTopLevel is not used to tell whether an object is
684 root_types or not (that can be achieved by testing this ==
685 root_types). But to see if this is a top-level *class* (not
686 necessarly our "toplevel" container).
688 2001-09-14 Ravi Pratap <ravi@ximian.com>
690 * enum.cs (Enum::Define): Modify to call the Lookup method on the

695 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
696 Modifiers.TypeAttr. This should just be a call to that method.

716 of top-level types as claimed.
718 2001-09-13 Miguel de Icaza <miguel@ximian.com>
720 * expression.cs (MemberLookup): Fruitless attempt to lookup
721 constructors. Maybe I need to emit default constructors? That
722 might be it (currently .NET emits this for me automatically).
723 (Invocation::OverloadResolve): Cope with Arguments == null.
724 (Invocation::EmitArguments): new function, shared by the new

770 (TypeContainer::Populate): Keep track of MethodBuilders to Method
773 (TypeContainer::FindMembers): Use ArrayList and then copy an array
774 of the exact size and return that.
776 (Class::LookupMethodByBuilder): New function that maps
777 MethodBuilders to its methods. Required to locate the information
778 on methods because System.Reflection bit us again.
780 * support.cs: New file, contains an interface ParameterData and
781 two implementations: ReflectionParameters and InternalParameters
782 used to access Parameter information. We will need to grow this
785 * expression.cs (Invocation::GetParameterData): implement a cache
786 and a wrapper around the ParameterData creation for methods.

892 * class.cs (Event::Define): Make the prefixes of the accessor methods
895 * genericparser.cs (GenericParser::error): Overloaded method to handle the case
896 of the location being passed in too. Ideally, this should go later since all
897 error reporting should be done through the Report object.
899 * class.cs (TypeContainer.Indexers): New property to access the list of indexers.
900 (Populate): Iterate thru the indexers we have and define them too.

945 on the name without any prefixes of namespace names etc. This is because we
946 already might have something already fully qualified like

1098 will is used during the tree rewriting as we resolve them during

1225 * class.cs (Property): Revamp to use the convention of making fields readonly.

1275 general catch clauses by being a little smart ;-)
1277 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
1278 Hooray, try and catch statements parse fine !

1332 (rank_specifiers): Update accordingly. Basically do the same
1333 thing - instead, collect the brackets here.
1334 (opt_rank_sepcifiers): Modify accordingly.
1335 (array_type): Modify to actually return the complete type string
1336 instead of ignoring the rank_specifiers.
1337 (expression_list): Implement to collect the expressions
1338 (variable_initializer): Implement. We make it a list of expressions
1339 essentially so that we can handle the array_initializer case neatly too.
1340 (variable_initializer_list): Implement.
1341 (array_initializer): Make it a list of variable_initializers
1342 (opt_array_initializer): Modify accordingly.
1344 * expression.cs (New::NType): Add enumeration to help us
1345 keep track of whether we have an object/delegate creation
1346 or an array creation.
1347 (New:NewType, New::Rank, New::Indices, New::Initializers): New
1348 members to hold data about array creation.
1349 (New:New): Modify to update NewType
1350 (New:New): New Overloaded contructor for the array creation
1353 * cs-parser.jay (array_creation_expression): Implement to call
1354 the overloaded New constructor.
1356 2001-08-26 Ravi Pratap <ravi@che.iitm.ac.in>
1358 * class.cs (TypeContainer::Constructors): Return member
1359 constructors instead of returning null.
1361 2001-08-26 Miguel de Icaza <miguel@ximian.com>
1363 * typemanager.cs (InitCoreTypes): Initialize the various core
1364 types after we have populated the type manager with the user
1365 defined types (this distinction will be important later while
1366 compiling corlib.dll)
1368 * expression.cs, literal.cs, assign.cs, constant.cs: Started work
1369 on Expression Classification. Now all expressions have a method
1370 `Resolve' and a method `Emit'.
1372 * codegen.cs, cs-parser.jay: Fixed the bug that stopped code
1373 generation from working. Also add some temporary debugging
1376 2001-08-24 Miguel de Icaza <miguel@ximian.com>
1378 * codegen.cs: Lots of code generation pieces. This is only the
1379 beginning, will continue tomorrow with more touches of polish. We
1380 handle the fundamentals of if, while, do, for, return. Others are
1381 trickier and I need to start working on invocations soon.
1383 * gen-treedump.cs: Bug fix, use s.Increment here instead of
1386 * codegen.cs (EmitContext): New struct, used during code
1387 emission to keep a context. Most of the code generation will be
1390 * cs-parser.jay: Add embedded blocks to the list of statements of
1391 this block. So code generation proceeds in a top down fashion.
1393 2001-08-23 Miguel de Icaza <miguel@ximian.com>
1395 * statement.cs: Add support for multiple child blocks.
1397 2001-08-22 Miguel de Icaza <miguel@ximian.com>
1399 * codegen.cs (EmitCode): New function, will emit the code for a
1400 Block of code given a TypeContainer and its ILGenerator.
1402 * statement.cs (Block): Standard public readonly optimization.
1403 (Block::Block constructors): Link children.
1404 (Block::Child): Child Linker.
1405 (Block::EmitVariables): Emits IL variable declarations.
1407 * class.cs: Drop support for MethodGroups here, delay until
1409 (Method::): Applied the same simplification that I did before, and
1410 move from Properties to public readonly fields.
1411 (Method::ParameterTypes): Returns the parameter types for the
1412 function, and implements a cache that will be useful later when I
1413 do error checking and the semantic analysis on the methods is
1415 (Constructor::GetCallingConvention): Renamed from CallingConvetion
1416 and made a method, optional argument tells whether this is a class
1417 or a structure to apply the `has-this' bit.
1418 (Method::GetCallingConvention): Implement, returns the calling
1420 (Method::Define): Defines the type, a second pass is performed
1421 later to populate the methods.
1423 (Constructor::ParameterTypes): implement a cache similar to the
1424 one on Method::ParameterTypes, useful later when we do semantic
1427 (TypeContainer::EmitMethod): New method. Emits methods.
1429 * expression.cs: Removed MethodGroup class from here.
1431 * parameter.cs (Parameters::GetCallingConvention): new method.
1433 2001-08-21 Miguel de Icaza <miguel@ximian.com>
1435 * class.cs (TypeContainer::Populate): Drop RootContext from the
1438 (Constructor::CallingConvention): Returns the calling convention.
1439 (Constructor::ParameterTypes): Returns the constructor parameter
1442 (TypeContainer::AddConstructor): Keep track of default constructor
1443 and the default static constructor.
1445 (Constructor::) Another class that starts using `public readonly'
1446 instead of properties.
1448 (Constructor::IsDefault): Whether this is a default constructor.
1450 (Field::) use readonly public fields instead of properties also.
1452 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
1453 track of static constructors; If none is used, turn on
1454 BeforeFieldInit in the TypeAttributes.
1456 * cs-parser.jay (opt_argument_list): now the return can be null
1457 for the cases where there are no arguments.
1459 (constructor_declarator): If there is no implicit `base' or
1460 `this', then invoke the default parent constructor.
1462 * modifiers.cs (MethodAttr): New static function maps a set of
1463 modifiers flags into a MethodAttributes enum
1464 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
1465 MethodAttr, TypeAttr to represent the various mappings where the
1467 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
1469 2001-08-19 Miguel de Icaza <miguel@ximian.com>
1471 * parameter.cs (GetParameterInfo): Fix bug where there would be no
1474 * interface.cs (PopulateIndexer): Implemented the code generator
1475 for interface indexers.
1477 2001-08-17 Miguel de Icaza <miguel@ximian.com>
1479 * interface.cs (InterfaceMemberBase): Now we track the new status
1482 (PopulateProperty): Implement property population. Woohoo! Got
1483 Methods and Properties going today.
1485 Removed all the properties for interfaces, and replaced them with
1486 `public readonly' fields.
1488 2001-08-16 Miguel de Icaza <miguel@ximian.com>
1490 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
1491 initialize their hashtables/arraylists only when they are needed
1492 instead of doing this always.
1494 * parameter.cs: Handle refs and out parameters.
1496 * cs-parser.jay: Use an ArrayList to construct the arguments
1497 instead of the ParameterCollection, and then cast that to a
1500 * parameter.cs: Drop the use of ParameterCollection and use
1501 instead arrays of Parameters.
1503 (GetParameterInfo): Use the Type, not the Name when resolving
1506 2001-08-13 Miguel de Icaza <miguel@ximian.com>
1508 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
1509 and instead use public readonly fields.
1511 * class.cs: Put back walking code for type containers.
1513 2001-08-11 Miguel de Icaza <miguel@ximian.com>
1515 * class.cs (MakeConstant): Code to define constants.
1517 * rootcontext.cs (LookupType): New function. Used to locate types
1520 2001-08-08 Miguel de Icaza <miguel@ximian.com>
1522 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
1523 this System.Reflection code is. Kudos to Microsoft
1525 * typemanager.cs: Implement a type cache and avoid loading all
1526 types at boot time. Wrap in LookupType the internals. This made
1527 the compiler so much faster. Wow. I rule!
1529 * driver.cs: Make sure we always load mscorlib first (for
1530 debugging purposes, nothing really important).
1532 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
1533 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
1535 * rootcontext.cs: Lookup types on their namespace; Lookup types
1536 on namespaces that have been imported using the `using' keyword.
1538 * class.cs (TypeContainer::TypeAttr): Virtualize.
1539 (Class::TypeAttr): Return attributes suitable for this bad boy.
1540 (Struct::TypeAttr): ditto.
1541 Handle nested classes.
1542 (TypeContainer::) Remove all the type visiting code, it is now
1543 replaced with the rootcontext.cs code
1545 * rootcontext.cs (GetClassBases): Added support for structs.
1547 2001-08-06 Miguel de Icaza <miguel@ximian.com>
1549 * interface.cs, statement.cs, class.cs, parameter.cs,
1550 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
1551 Drop use of TypeRefs, and use strings instead.
1553 2001-08-04 Miguel de Icaza <miguel@ximian.com>
1557 * class.cs (Struct::Struct): set the SEALED flags after
1558 checking the modifiers.
1559 (TypeContainer::TypeAttr): new property, returns the
1560 TypeAttributes for a class.
1562 * cs-parser.jay (type_list): Oops, list production was creating a
1563 new list of base types.
1565 * rootcontext.cs (StdLib): New property.
1566 (GetInterfaceTypeByName): returns an interface by type name, and
1567 encapsulates error handling here.
1568 (GetInterfaces): simplified.
1569 (ResolveTree): Encapsulated all the tree resolution here.
1570 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
1573 * driver.cs: Add support for --nostdlib, to avoid loading the
1575 (Main): Do not put tree resolution here.
1577 * rootcontext.cs: Beginning of the class resolution.
1579 2001-08-03 Miguel de Icaza <miguel@ximian.com>
1581 * rootcontext.cs: Provide better error reporting.
1583 * cs-parser.jay (interface_base): set our $$ to be interfaces.
1585 * rootcontext.cs (CreateInterface): Handle the case where there
1586 are no parent interfaces.
1588 (CloseTypes): Routine to flush types at the end.
1589 (CreateInterface): Track types.
1590 (GetInterfaces): Returns an array of Types from the list of
1593 * typemanager.c (AddUserType): Mechanism to track user types (puts
1594 the type on the global type hash, and allows us to close it at the
1597 2001-08-02 Miguel de Icaza <miguel@ximian.com>
1599 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
1600 RecordInterface instead.
1602 * cs-parser.jay: Updated to reflect changes above.
1604 * decl.cs (Definition): Keep track of the TypeBuilder type that
1605 represents this type here. Not sure we will use it in the long
1606 run, but wont hurt for now.
1608 * driver.cs: Smaller changes to accomodate the new code.
1610 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
1613 * rootcontext.cs (CreateInterface): New method, used to create
1614 the System.TypeBuilder type for interfaces.
1615 (ResolveInterfaces): new entry point to resolve the interface
1617 (CodeGen): Property, used to keep track of the code generator.
1619 2001-07-26 Miguel de Icaza <miguel@ximian.com>
1621 * cs-parser.jay: Add a second production for delegate_declaration
1624 (enum_body): Put an opt_comma here instead of putting it on
1625 enum_body or enum_member_declarations so we can handle trailing
1626 commas on enumeration members. Gets rid of a shift/reduce.
1628 (type_list): Need a COMMA in the middle.
1630 (indexer_declaration): Tell tokenizer to recognize get/set
1632 * Remove old targets.
1634 * Re-add the parser target.
1636 2001-07-13 Simon Cozens <simon@simon-cozens.org>
1638 * cs-parser.jay: Add precendence rules for a number of operators
1639 ot reduce the number of shift/reduce conflicts in the grammar.
1641 2001-07-17 Miguel de Icaza <miguel@ximian.com>
1643 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
1646 Get rid of old crufty code.
1648 * rootcontext.cs: Use this to keep track of the parsed
1649 representation and the defined types available to the program.
1651 * gen-treedump.cs: adjust for new convention.
1653 * type.cs: Split out the type manager, and the assembly builder
1656 * typemanager.cs: the type manager will live here now.
1658 * cil-codegen.cs: And the code generator here.
1660 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
1662 * makefile: Fixed up for easy making.
1664 2001-07-13 Simon Cozens <simon@simon-cozens.org>
1666 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
1669 (unary_expression): Expand pre_increment_expression and
1670 post_decrement_expression to reduce a shift/reduce.
1672 2001-07-11 Simon Cozens
1674 * cs-tokenizer.cs: Hex numbers should begin with a 0.
1676 Improve allow_keyword_as_indent name.
1678 2001-06-19 Miguel de Icaza <miguel@ximian.com>
1680 * Adjustments for Beta2.
1682 2001-06-13 Miguel de Icaza <miguel@ximian.com>
1684 * decl.cs: Added `Define' abstract method.
1685 (InTransit): new property, used to catch recursive definitions.
1687 * interface.cs: Implement `Define'.
1689 * modifiers.cs: Map Modifiers.constants to
1690 System.Reflection.TypeAttribute flags.
1692 * class.cs: Keep track of types and user-defined types.
1693 (BuilderInit): New method for creating an assembly
1694 (ResolveType): New function to launch the resolution process, only
1695 used by interfaces for now.
1697 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
1698 that are inserted into the name space.
1700 2001-06-08 Miguel de Icaza <miguel@ximian.com>
1702 * ARGH. I have screwed up my tree so many times due to the use of
1703 rsync rather than using CVS. Going to fix this at once.
1705 * driver.cs: Objetify driver. Load assemblies, use assemblies to
1708 2001-06-07 Miguel de Icaza <miguel@ximian.com>
1710 * Experiment successful: Use System.Type rather that our own
1713 2001-05-25 Miguel de Icaza <miguel@ximian.com>
1715 * cs-parser.jay: Removed nsAliases from here.
1717 Use new namespaces, handle `using XXX;'
1719 * namespace.cs: Reimplemented namespace handling, use a recursive
1720 definition of the class. Now we can keep track of using clauses
1721 and catch invalid using clauses.
1723 2001-05-24 Miguel de Icaza <miguel@ximian.com>
1725 * gen-treedump.cs: Adapted for all the renaming.
1727 * expression.cs (Expression): this class now has a Type property
1728 which returns an expression Type.
1730 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
1731 `Type', as this has a different meaning now in the base
1733 2001-05-22 Miguel de Icaza <miguel@ximian.com>
1735 * interface.cs, class.cs: Removed from all the sources the
1736 references to signature computation, as we can not do method
1737 signature computation during the parsing time, as we are not
1738 trying to solve at that point distinguishing:
1742 void a (NS.Blah x) {}
1745 Which depending on the context might be valid or not, as we do not
1746 know if Blah is the same thing as NS.Blah at that point.
1748 * Redid everything so the code uses TypeRefs now instead of
1749 Types. TypeRefs are just temporary type placeholders, that need
1750 to be resolved. They initially have a pointer to a string and the
1751 current scope in which they are used. This is used later by the
1752 compiler to resolve the reference to an actual Type.
1754 * DeclSpace is no longer a CIR.Type, and neither are
1755 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
1756 are all DeclSpaces, but no Types.
1758 * type.cs (TypeRefManager): This implements the TypeRef manager,
1759 which keeps track of all the types that need to be resolved after
1760 the parsing has finished.
1762 2001-05-13 Miguel de Icaza <miguel@ximian.com>
1764 * ARGH. We are going to have to store `foreach' as a class rather
1765 than resolving it, as we need to verify error 1579 after name
1766 resolution. *OR* we could keep a flag that says `This request to
1767 IEnumerator comes from a foreach statement' which we can then use
1768 to generate the error.
1770 2001-05-10 Miguel de Icaza <miguel@ximian.com>
1772 * class.cs (TypeContainer.AddMethod): we now add methods to the
1773 MethodGroup instead of the method hashtable.
1775 * expression.cs: Add MethodGroup abstraction, which gets us one
1776 step closer to the specification in the way we handle method
1779 * cs-parser.jay (primary_expression): qualified_identifier now
1780 tried to match up an identifier to a local variable reference or
1781 to a parameter reference.
1783 current_local_parameters is now a parser global variable that
1784 points to the current parameters for the block, used during name
1787 (property_declaration): Now creates an implicit `value' argument to
1790 2001-05-09 Miguel de Icaza <miguel@ximian.com>
1792 * parameter.cs: Do not use `param' arguments as part of the
1793 signature, per the spec.
1795 2001-05-08 Miguel de Icaza <miguel@ximian.com>
1797 * decl.cs: Base class for classes, structs and interfaces. This
1798 is the "Declaration Space"
1800 * cs-parser.jay: Use CheckDef for checking declaration errors
1801 instead of having one on each function.
1803 * class.cs: Factor out some code for handling error handling in
1804 accordance to the "Declarations" section in the "Basic Concepts"
1805 chapter in the ECMA C# spec.
1807 * interface.cs: Make all interface member classes derive from
1808 InterfaceMemberBase.
1810 2001-05-07 Miguel de Icaza <miguel@ximian.com>
1812 * Many things: all interfaces are parsed and generated in
1813 gen-treedump. Support for member variables, constructors,
1814 destructors, properties, constants is there.
1816 Beginning of the IL backend, but very little done, just there for
1819 2001-04-29 Miguel de Icaza <miguel@ximian.com>
1821 * cs-parser.jay: Fix labeled statement.
1823 * cs-tokenizer.cs (escape): Escape " and ' always.
1824 ref_line, ref_name: keep track of the line/filename as instructed
1825 by #line by the compiler.
1828 2001-04-27 Miguel de Icaza <miguel@ximian.com>
1830 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
1831 to match the values in System.CodeDOM.
1833 Divid renamed to Divide.
1835 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
1837 (Statements.set): remove.
1839 * System.CodeDOM/CodeCatchClause.cs: always have a valid
1842 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
1843 falseStatements always have valid values.
1845 * cs-parser.jay: Use System.CodeDOM now.
