1 2001-09-30 Miguel de Icaza <miguel@ximian.com>
3 * expression.cs (report118): require location argument.
5 * parameter.cs: Do not dereference potential null value.
7 * class.cs: Catch methods that lack the `new' keyword when
8 overriding a name. Report warnings when `new' is used without
9 anything being there to override.
11 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
13 * class.cs: Only add constructor to hashtable if it is non-null
14 (as now constructors can fail on define).
16 (TypeManager, Class, Struct): Take location arguments.
18 Catch field instance initialization in structs as errors.
20 accepting_filter: a new filter for FindMembers that is static so
21 that we dont create an instance per invocation.
23 (Constructor::Define): Catch errors where a struct constructor is
26 * cs-parser.jay: Pass location information for various new
29 * delegate.cs (Delegate): take a location argument.
31 * driver.cs: Do not call EmitCode if there were problesm in the
32 Definition of the types, as many Builders wont be there.
34 * decl.cs (Decl::Decl): Require a location argument.
36 * cs-tokenizer.cs: Handle properly hex constants that can not fit
37 into integers, and find the most appropiate integer for it.
39 * literal.cs: Implement ULongLiteral.
41 * rootcontext.cs: Provide better information about the location of
42 failure when CreateType fails.
44 2001-09-29 Miguel de Icaza <miguel@ximian.com>
46 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
49 * expression.cs (Binary::CheckShiftArguments): Add missing type
51 (Binary::ResolveOperator): Add type to the logical and and logical
52 or, Bitwise And/Or and Exclusive Or code paths, it was missing
55 (Binary::DoNumericPromotions): In the case where either argument
56 is ulong (and most signed types combined with ulong cause an
57 error) perform implicit integer constant conversions as well.
59 2001-09-28 Miguel de Icaza <miguel@ximian.com>
61 * expression.cs (UserImplicitCast): Method should always be
63 (Invocation::BetterConversion): Simplified test for IntLiteral.
65 (Expression::ImplicitNumericConversion): Split this routine out.
66 Put the code that performs implicit constant integer conversions
69 (Expression::Resolve): Become a wrapper around DoResolve so we can
70 check eclass and type being set after resolve.
72 (Invocation::Badness): Remove this dead function
74 (Binary::ResolveOperator): Do not compute the expensive argumnets
75 unless we have a union for it.
77 (Probe::Emit): Is needs to do an isinst and then
80 (::CanConvert): Added Location argument. If the Location argument
81 is null (Location.Null), then we do not report errors. This is
82 used by the `probe' mechanism of the Explicit conversion. We do
83 not want to generate an error for something that the user
84 explicitly requested to be casted. But the pipeline for an
85 explicit cast first tests for potential implicit casts.
87 So for now, if the Location is null, it means `Probe only' to
88 avoid adding another argument. Might have to revise this
91 (ClassCast): New class used to type cast objects into arbitrary
92 classes (used in Explicit Reference Conversions).
94 Implement `as' as well.
96 Reverted all the patches from Ravi below: they were broken:
98 * The use of `level' as a mechanism to stop recursive
99 invocations is wrong. That was there just to catch the
100 bug with a strack trace but not as a way of addressing
103 To fix the problem we have to *understand* what is going
104 on and the interactions and come up with a plan, not
105 just get things going.
107 * The use of the type conversion cache that I proposed
108 last night had an open topic: How does this work across
109 protection domains. A user defined conversion might not
110 be public in the location where we are applying the
111 conversion, a different conversion might be selected
112 (ie, private A->B (better) but public B->A (worse),
113 inside A, A->B applies, but outside it, B->A will
116 * On top of that (ie, even if the above is solved),
117 conversions in a cache need to be abstract. Ie, `To
118 convert from an Int to a Short use an OpcodeCast', not
119 `To convert from an Int to a Short use the OpcodeCast on
120 the variable 5' (which is what this patch was doing).
122 2001-09-28 Ravi Pratap <ravi@ximian.com>
124 * expression.cs (Invocation::ConversionExists): Re-write to use
127 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
128 cache all conversions done, not just user-defined ones.
130 (Invocation::BetterConversion): The real culprit. Use ConversionExists
131 to determine if a conversion exists instead of acutually trying to
132 perform the conversion. It's faster too.
134 (Expression::ConvertExplicit): Modify to use ConversionExists to check
135 and only then attempt the implicit conversion.
137 2001-09-28 Ravi Pratap <ravi@ximian.com>
139 * expression.cs (ConvertImplicit): Use a cache for conversions
140 already found. Check level of recursion and bail out if necessary.
142 2001-09-28 Miguel de Icaza <miguel@ximian.com>
144 * typemanager.cs (string_concat_string_string, string_concat_object_object):
145 Export standard methods that we expect for string operations.
147 * statement.cs (Block::UsageWarning): Track usage of variables and
148 report the errors for not used variables.
150 * expression.cs (Conditional::Resolve, ::Emit): Implement ?:
153 2001-09-27 Miguel de Icaza <miguel@ximian.com>
155 * codegen.cs: remove unnneded code
157 * expression.cs: Removed BuiltinTypeAccess class
159 Fix the order in which implicit conversions are
162 The previous fixed dropped support for boxed conversions (adding a
163 test to the test suite now)
165 (UserImplicitCast::CanConvert): Remove test for source being null,
166 that code is broken. We should not feed a null to begin with, if
167 we do, then we should track the bug where the problem originates
168 and not try to cover it up here.
170 Return a resolved expression of type UserImplicitCast on success
171 rather than true/false. Ravi: this is what I was talking about,
172 the pattern is to use a static method as a "constructor" for
175 Also, do not create arguments until the very last minute,
176 otherwise we always create the arguments even for lookups that
177 will never be performed.
179 (UserImplicitCast::Resolve): Eliminate, objects of type
180 UserImplicitCast are born in a fully resolved state.
182 * typemanager.cs (InitCoreTypes): Init also value_type
185 * expression.cs (Cast::Resolve): First resolve the child expression.
187 (LValue): Add new method AddressOf to be used by
190 Change the argument of Store to take an EmitContext instead of an
191 ILGenerator, because things like FieldExpr need to be able to call
192 their children expression to generate the instance code.
194 (Expression::Error, Expression::Warning): Sugar functions for
197 (Expression::MemberLookup): Accept a TypeContainer instead of a
198 Report as the first argument.
200 (Expression::ResolvePrimary): Killed. I still want to improve
201 this as currently the code is just not right.
203 (Expression::ResolveMemberAccess): Simplify, but it is still
206 (Unary::Resolve): Catch errors in AddressOf operators.
208 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
209 index to a byte for the short-version, or the compiler will choose
210 the wrong Emit call, which generates the wrong data.
212 (ParameterReference::Emit, ::Store): same.
214 (FieldExpr::AddressOf): Implement.
216 * typemanager.cs: TypeManager: made public variable instead of
219 * driver.cs: document --fatal.
221 * report.cs (ErrorMessage, WarningMessage): new names for the old
222 Error and Warning classes.
224 * cs-parser.jay (member_access): Turn built-in access to types
225 into a normal simplename
227 2001-09-27 Ravi Pratap <ravi@ximian.com>
229 * expression.cs (Invocation::BetterConversion): Fix to cope
230 with q being null, since this was introducing a bug.

240 * class.cs (TypeContainer::AddConstructor): Fix a stupid bug
241 I had introduced long ago (what's new ?).
243 * expression.cs (UserImplicitCast::CanConvert): Static method to do
244 the work of all the checking.
245 (ConvertImplicit): Call CanConvert and only then create object if necessary.
246 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
248 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
249 that is the right way.
251 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
252 overloading resolution. Use everywhere instead of cutting and pasting code.
254 (Binary::ResolveOperator): Use MakeUnionSet.
256 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
257 we have to convert to bool types. Not complete yet.
259 2001-09-27 Miguel de Icaza <miguel@ximian.com>
261 * typemanager.cs (TypeManager::CSharpName): support ushort.
263 * expression.cs (Expression::TryImplicitIntConversion): Attempts
264 to provide an expression that performsn an implicit constant int
265 conversion (section 6.1.6).
266 (Expression::ConvertImplicitRequired): Reworked to include
267 implicit constant expression conversions.
269 (Expression::ConvertNumericExplicit): Finished.
271 (Invocation::Emit): If InstanceExpression is null, then it means
272 that we perform a call on this.
274 2001-09-26 Miguel de Icaza <miguel@ximian.com>
276 * expression.cs (Unary::Emit): Remove some dead code.
277 (Probe): Implement Resolve and Emit for `is'.
278 (Expression::ConvertImplicitRequired): Attempt to do constant
279 expression conversions here. Maybe should be moved to
280 ConvertImplicit, but I am not sure.
281 (Expression::ImplicitLongConstantConversionPossible,
282 Expression::ImplicitIntConstantConversionPossible): New functions
283 that tell whether is it possible to apply an implicit constant
284 expression conversion.
286 (ConvertNumericExplicit): Started work on explicit numeric
289 * cs-parser.jay: Update operator constants.
291 * parameter.cs (Parameters::GetParameterInfo): Hook up VerifyArgs

293 (Parameters::VerifyArgs): Verifies that no two arguments have the
296 * class.cs (Operator): Update the operator names to reflect the
297 ones that the spec expects (as we are just stringizing the
300 * expression.cs (Unary::ResolveOperator): Fix bug: Use
301 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
302 previous usage did only work for our methods.
303 (Expression::ConvertImplicit): Handle decimal implicit numeric
305 (Expression::InternalTypeConstructor): Used to invoke constructors
306 on internal types for default promotions.
308 (Unary::Emit): Implement special handling for the pre/post
309 increment/decrement for overloaded operators, as they need to have
310 the same semantics as the other operators.
312 (Binary::ResolveOperator): ditto.
313 (Invocation::ConversionExists): ditto.
314 (UserImplicitCast::Resolve): ditto.
316 2001-09-26 Ravi Pratap <ravi@ximian.com>

330 * assign.cs (Assign): Make it inherit from ExpressionStatement.
332 * expression.cs (ExpressionStatement): New base class used for
333 expressions that can appear in statements, so that we can provide
334 an alternate path to generate expression that do not leave a value
337 (Expression::Emit, and all the derivatives): We no longer return
338 whether a value is left on the stack or not. Every expression
339 after being emitted leaves a single value on the stack.
341 * codegen.cs (EmitContext::EmitStatementExpression): Use the
342 facilties of ExpressionStatement if possible.
344 * cs-parser.jay: Update statement_expression.

369 * assign.cs: track location.
370 (Resolve): Use implicit conversions on assignment.
372 * literal.cs: Oops. Not good, Emit of short access values should
373 pass (Bytes) or the wrong argument will be selected.
375 * expression.cs (Unary::Emit): Emit code for -expr.
377 (Unary::ResolveOperator): Handle `Substract' for non-constants
378 (substract from zero from the non-constants).

414 Also take an additional TypeContainer argument.
416 * All over : Pass in TypeContainer as argument to OverloadResolve.
418 * typemanager.cs (CSharpName): Update to check for the string type and return
421 * expression.cs (Invocation::FullMethodDesc): New static method to return a string fully describing

435 * typemanager.cs: declare and load enum_type, delegate_type and
438 * expression.cs (Expression::Emit): Now emit returns a value that
439 tells whether a value is left on the stack or not. This strategy
440 might be reveted tomorrow with a mechanism that would address
441 multiple assignments.
442 (Expression::report118): Utility routine to report mismatches on

456 * All Expression derivatives: Updated their Emit method to return
457 whether they leave values on the stack or not.
459 * codegen.cs (CodeGen::EmitStatement): Pop values left on the
460 stack for expressions that are statements.
462 2001-09-20 Miguel de Icaza <miguel@ximian.com>
464 * expression.cs (LValue): New interface. Must be implemented by

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

513 expression for expressions which are just +expr.

542 (Unary.method, .Arguments): Add.
543 (Unary::OperName): Implement.
544 (Unary::ForceConversion): Copy and Paste !
546 * class.cs (Operator::Define): Fix a small bug for the case when we have
549 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
550 for the inbuilt operators. Only overloading works for now ;-)
552 2001-09-18 Miguel de Icaza <miguel@ximian.com>
554 * expression.cs (CheckedExpr::Resolve, CheckedExpr::Emit,

568 (FieldExpr::Emit): Implement.
570 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
571 the last instruction contains a return opcode to avoid generating
572 the last `ret' instruction (this generates correct code, and it is
573 nice to pass the peverify output).
575 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
576 initializer for static and instance variables.
577 (Constructor::Emit): Allow initializer to be null in the case of
578 static constructors. Only emit initializer for instance

596 initializers if none was specified.
597 Catch the fact that constructors should not have parameters.
599 * class.cs: Do not emit parent class initializers for static
600 constructors, that should be flagged as an error.
602 2001-09-18 Ravi Pratap <ravi@ximian.com>

631 * expression.cs (Expression::OverloadResolve): Drop TypeContainer
634 (Expression::MemberLookup): Provide a version that allows to
635 specify the MemberTypes and BindingFlags.

641 Beforefieldinit as it was buggy.
643 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200
646 * class.cs (Constructor::Emit): Only emit if block is not null.
647 (TypeContainer::EmitDefaultConstructor): Removed routine, now we
648 deal with this by semantically definining it as if the user had
651 (TypeContainer::FindMembers): Removed ad-hoc hack to deal with
652 constructors as we now "emit" them at a higher level.
654 (TypeContainer::DefineDefaultConstructor): Used to define the
655 default constructors if none was provided.
657 (ConstructorInitializer): Add methods Resolve and Emit.

709 * interface.cs (Interface::InterfaceAttr): Re-write to be more correct and complete.
710 (Interface::IsTopLevel): Add. Same as TypeContainer::IsTopLevel.
712 * class.cs (TypeContainer::IsTopLevel): Modify to use parent.Parent instead

722 * cs-parser.jay (namespace_declaration): Call RecordNamespace to
725 * rootcontext.cs (IsNamespace): Fixed it :-)
727 2001-09-14 Miguel de Icaza <miguel@ximian.com>

736 Load System assembly as well as part of the standard library.
738 * report.cs: Allow throwing exceptions on errors for debugging.
740 * modifiers.cs: Do not use `parent', instead use the real type
741 container to evaluate permission settings.
743 * class.cs: Put Ravi's patch back in. He is right, and we will
744 have to cope with the
746 2001-09-14 Ravi Pratap <ravi@ximian.com>
748 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to

753 * driver.cs: Added --parse option that only parses its input files
756 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
757 incorrect. IsTopLevel is not used to tell whether an object is
758 root_types or not (that can be achieved by testing this ==
759 root_types). But to see if this is a top-level *class* (not
760 necessarly our "toplevel" container).
762 2001-09-14 Ravi Pratap <ravi@ximian.com>
764 * enum.cs (Enum::Define): Modify to call the Lookup method on the
765 parent instead of a direct call to GetType.
767 2001-09-14 Ravi Pratap <ravi@ximian.com>

784 to precisely that info.
786 * modifiers.cs (MethodAttr): Re-write.
787 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
789 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
790 of top-level types as claimed.
792 2001-09-13 Miguel de Icaza <miguel@ximian.com>
794 * expression.cs (MemberLookup): Fruitless attempt to lookup
795 constructors. Maybe I need to emit default constructors? That
796 might be it (currently .NET emits this for me automatically).
797 (Invocation::OverloadResolve): Cope with Arguments == null.
798 (Invocation::EmitArguments): new function, shared by the new

824 * expression.cs (PropertyExpr): Initialize type from the
827 * codegen.cs (EmitContext::EmitBoolExpression): Use propper

832 (Binary::ResolveOperator): Set the return type to boolean for
833 comparission operators
835 * typemanager.cs: Remove debugging print code.
837 (Invocation::Resolve): resolve type.
839 * class.cs: Allocate a MemberInfo of the correct size, as the code
840 elsewhere depends on the test to reflect the correct contents.
842 (Method::) Keep track of parameters, due to System.Reflection holes
844 (TypeContainer::Populate): Keep track of MethodBuilders to Method
847 (TypeContainer::FindMembers): Use ArrayList and then copy an array
848 of the exact size and return that.
850 (Class::LookupMethodByBuilder): New function that maps
851 MethodBuilders to its methods. Required to locate the information
852 on methods because System.Reflection bit us again.
854 * support.cs: New file, contains an interface ParameterData and
855 two implementations: ReflectionParameters and InternalParameters
856 used to access Parameter information. We will need to grow this
859 * expression.cs (Invocation::GetParameterData): implement a cache
860 and a wrapper around the ParameterData creation for methods.

874 initialized with the full type once it is resolved.
876 2001-09-12 Miguel de Icaza <miguel@ximian.com>
878 * parameter.cs (GetParameterInfo): Use a type cache to compute
879 things only once, and to reuse this information
881 * expression.cs (LocalVariableReference::Emit): Implement.
882 (OpcodeCast::Emit): fix.
884 (ParameterReference::Resolve): Implement.
885 (ParameterReference::Emit): Implement.
887 * cs-parser.jay: Fix bug introduced by Ravi, variable initializers

920 what Type.FindMembers does, only we don't have to use reflection. No
923 * typemanager.cs (typecontainers): New hashtable to hold the corresponding
924 typecontainer objects as we need to get at them.
925 (TypeManager::AddUserType): Overload to take an extra argument, the TypeContainer.

928 typecontainer object.

931 of just a Report object.
933 2001-09-11 Ravi Pratap <ravi@ximian.com>

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

1016 (CheckBinaryOperator): Same here.
1018 * rootcontext.cs (LookupType): Add an extra lookup which simply does a lookup

1172 will is used during the tree rewriting as we resolve them during

1299 * class.cs (Property): Revamp to use the convention of making fields readonly.

1348 and re-write the code in the actions to extract the specific and
1349 general catch clauses by being a little smart ;-)
1351 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
1352 Hooray, try and catch statements parse fine !
1354 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
1356 * statement.cs (Block::GetVariableType): Fix logic to extract the type
1357 string from the hashtable of variables.
1359 * cs-parser.jay (event_accessor_declarations): Trivial fix. Man, how did
1360 I end up making that mistake ;-)
1361 (catch_clauses): Fixed gross error which made Key and Value of the
1362 DictionaryEntry the same : $1 !!
1364 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
1366 * cs-tokenizer.cs (initTokens): Add keywords 'add' and 'remove'
1368 * cs-parser.jay (event_declaration): Correct to remove the semicolon
1369 when the add and remove accessors are specified.
1371 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
1373 * cs-parser.jay (IndexerDeclaration): New helper class to hold
1374 information about indexer_declarator.
1375 (indexer_declarator): Implement actions.
1376 (parsing_indexer): New local boolean used to keep track of whether
1377 we are parsing indexers or properties. This is necessary because
1378 implicit_parameters come into picture even for the get accessor in the
1380 (get_accessor_declaration, set_accessor_declaration): Correspondingly modified.
1382 * class.cs (Indexer): New class for indexer declarations.
1383 (TypeContainer::AddIndexer): New method to add an indexer to a type.
1384 (TypeContainer::indexers): New member to hold list of indexers for the
1387 2001-08-27 Ravi Pratap <ravi@che.iitm.ac.in>
1389 * cs-parser.jay (add_accessor_declaration): Implement action.
1390 (remove_accessor_declaration): Implement action.
1391 (event_accessors_declaration): Implement
1392 (variable_declarators): swap statements for first rule - trivial.
1394 * class.cs (Event): New class to hold information about event
1396 (TypeContainer::AddEvent): New method to add an event to a type
1397 (TypeContainer::events): New member to hold list of events.
1399 * cs-parser.jay (event_declaration): Implement actions.
1401 2001-08-27 Ravi Pratap <ravi@che.iitm.ac.in>
1403 * cs-parser.jay (dim_separators): Implement. Make it a string
1404 concatenating all the commas together, just as they appear.
1405 (opt_dim_separators): Modify accordingly
1406 (rank_specifiers): Update accordingly. Basically do the same
1407 thing - instead, collect the brackets here.
1408 (opt_rank_sepcifiers): Modify accordingly.
1409 (array_type): Modify to actually return the complete type string
1410 instead of ignoring the rank_specifiers.
1411 (expression_list): Implement to collect the expressions
1412 (variable_initializer): Implement. We make it a list of expressions
1413 essentially so that we can handle the array_initializer case neatly too.
1414 (variable_initializer_list): Implement.
1415 (array_initializer): Make it a list of variable_initializers
1416 (opt_array_initializer): Modify accordingly.
1418 * expression.cs (New::NType): Add enumeration to help us
1419 keep track of whether we have an object/delegate creation
1420 or an array creation.
1421 (New:NewType, New::Rank, New::Indices, New::Initializers): New
1422 members to hold data about array creation.
1423 (New:New): Modify to update NewType
1424 (New:New): New Overloaded contructor for the array creation
1427 * cs-parser.jay (array_creation_expression): Implement to call
1428 the overloaded New constructor.
1430 2001-08-26 Ravi Pratap <ravi@che.iitm.ac.in>
1432 * class.cs (TypeContainer::Constructors): Return member
1433 constructors instead of returning null.
1435 2001-08-26 Miguel de Icaza <miguel@ximian.com>
1437 * typemanager.cs (InitCoreTypes): Initialize the various core
1438 types after we have populated the type manager with the user
1439 defined types (this distinction will be important later while
1440 compiling corlib.dll)
1442 * expression.cs, literal.cs, assign.cs, constant.cs: Started work
1443 on Expression Classification. Now all expressions have a method
1444 `Resolve' and a method `Emit'.
1446 * codegen.cs, cs-parser.jay: Fixed the bug that stopped code
1447 generation from working. Also add some temporary debugging
1450 2001-08-24 Miguel de Icaza <miguel@ximian.com>
1452 * codegen.cs: Lots of code generation pieces. This is only the
1453 beginning, will continue tomorrow with more touches of polish. We
1454 handle the fundamentals of if, while, do, for, return. Others are
1455 trickier and I need to start working on invocations soon.
1457 * gen-treedump.cs: Bug fix, use s.Increment here instead of
1460 * codegen.cs (EmitContext): New struct, used during code
1461 emission to keep a context. Most of the code generation will be
1464 * cs-parser.jay: Add embedded blocks to the list of statements of
1465 this block. So code generation proceeds in a top down fashion.
1467 2001-08-23 Miguel de Icaza <miguel@ximian.com>
1469 * statement.cs: Add support for multiple child blocks.
1471 2001-08-22 Miguel de Icaza <miguel@ximian.com>
1473 * codegen.cs (EmitCode): New function, will emit the code for a
1474 Block of code given a TypeContainer and its ILGenerator.
1476 * statement.cs (Block): Standard public readonly optimization.
1477 (Block::Block constructors): Link children.
1478 (Block::Child): Child Linker.
1479 (Block::EmitVariables): Emits IL variable declarations.
1481 * class.cs: Drop support for MethodGroups here, delay until
1483 (Method::): Applied the same simplification that I did before, and
1484 move from Properties to public readonly fields.
1485 (Method::ParameterTypes): Returns the parameter types for the
1486 function, and implements a cache that will be useful later when I
1487 do error checking and the semantic analysis on the methods is
1489 (Constructor::GetCallingConvention): Renamed from CallingConvetion
1490 and made a method, optional argument tells whether this is a class
1491 or a structure to apply the `has-this' bit.
1492 (Method::GetCallingConvention): Implement, returns the calling
1494 (Method::Define): Defines the type, a second pass is performed
1495 later to populate the methods.
1497 (Constructor::ParameterTypes): implement a cache similar to the
1498 one on Method::ParameterTypes, useful later when we do semantic
1501 (TypeContainer::EmitMethod): New method. Emits methods.
1503 * expression.cs: Removed MethodGroup class from here.
1505 * parameter.cs (Parameters::GetCallingConvention): new method.
1507 2001-08-21 Miguel de Icaza <miguel@ximian.com>
1509 * class.cs (TypeContainer::Populate): Drop RootContext from the
1512 (Constructor::CallingConvention): Returns the calling convention.
1513 (Constructor::ParameterTypes): Returns the constructor parameter
1516 (TypeContainer::AddConstructor): Keep track of default constructor
1517 and the default static constructor.
1519 (Constructor::) Another class that starts using `public readonly'
1520 instead of properties.
1522 (Constructor::IsDefault): Whether this is a default constructor.
1524 (Field::) use readonly public fields instead of properties also.
1526 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
1527 track of static constructors; If none is used, turn on
1528 BeforeFieldInit in the TypeAttributes.
1530 * cs-parser.jay (opt_argument_list): now the return can be null
1531 for the cases where there are no arguments.
1533 (constructor_declarator): If there is no implicit `base' or
1534 `this', then invoke the default parent constructor.
1536 * modifiers.cs (MethodAttr): New static function maps a set of
1537 modifiers flags into a MethodAttributes enum
1538 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
1539 MethodAttr, TypeAttr to represent the various mappings where the
1541 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
1543 2001-08-19 Miguel de Icaza <miguel@ximian.com>
1545 * parameter.cs (GetParameterInfo): Fix bug where there would be no
1548 * interface.cs (PopulateIndexer): Implemented the code generator
1549 for interface indexers.
1551 2001-08-17 Miguel de Icaza <miguel@ximian.com>
1553 * interface.cs (InterfaceMemberBase): Now we track the new status
1556 (PopulateProperty): Implement property population. Woohoo! Got
1557 Methods and Properties going today.
1559 Removed all the properties for interfaces, and replaced them with
1560 `public readonly' fields.
1562 2001-08-16 Miguel de Icaza <miguel@ximian.com>
1564 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
1565 initialize their hashtables/arraylists only when they are needed
1566 instead of doing this always.
1568 * parameter.cs: Handle refs and out parameters.
1570 * cs-parser.jay: Use an ArrayList to construct the arguments
1571 instead of the ParameterCollection, and then cast that to a
1574 * parameter.cs: Drop the use of ParameterCollection and use
1575 instead arrays of Parameters.
1577 (GetParameterInfo): Use the Type, not the Name when resolving
1580 2001-08-13 Miguel de Icaza <miguel@ximian.com>
1582 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
1583 and instead use public readonly fields.
1585 * class.cs: Put back walking code for type containers.
1587 2001-08-11 Miguel de Icaza <miguel@ximian.com>
1589 * class.cs (MakeConstant): Code to define constants.
1591 * rootcontext.cs (LookupType): New function. Used to locate types
1594 2001-08-08 Miguel de Icaza <miguel@ximian.com>
1596 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
1597 this System.Reflection code is. Kudos to Microsoft
1599 * typemanager.cs: Implement a type cache and avoid loading all
1600 types at boot time. Wrap in LookupType the internals. This made
1601 the compiler so much faster. Wow. I rule!
1603 * driver.cs: Make sure we always load mscorlib first (for
1604 debugging purposes, nothing really important).
1606 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
1607 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
1609 * rootcontext.cs: Lookup types on their namespace; Lookup types
1610 on namespaces that have been imported using the `using' keyword.
1612 * class.cs (TypeContainer::TypeAttr): Virtualize.
1613 (Class::TypeAttr): Return attributes suitable for this bad boy.
1614 (Struct::TypeAttr): ditto.
1615 Handle nested classes.
1616 (TypeContainer::) Remove all the type visiting code, it is now
1617 replaced with the rootcontext.cs code
1619 * rootcontext.cs (GetClassBases): Added support for structs.
1621 2001-08-06 Miguel de Icaza <miguel@ximian.com>
1623 * interface.cs, statement.cs, class.cs, parameter.cs,
1624 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
1625 Drop use of TypeRefs, and use strings instead.
1627 2001-08-04 Miguel de Icaza <miguel@ximian.com>
1631 * class.cs (Struct::Struct): set the SEALED flags after
1632 checking the modifiers.
1633 (TypeContainer::TypeAttr): new property, returns the
1634 TypeAttributes for a class.
1636 * cs-parser.jay (type_list): Oops, list production was creating a
1637 new list of base types.
1639 * rootcontext.cs (StdLib): New property.
1640 (GetInterfaceTypeByName): returns an interface by type name, and
1641 encapsulates error handling here.
1642 (GetInterfaces): simplified.
1643 (ResolveTree): Encapsulated all the tree resolution here.
1644 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
1647 * driver.cs: Add support for --nostdlib, to avoid loading the
1649 (Main): Do not put tree resolution here.
1651 * rootcontext.cs: Beginning of the class resolution.
1653 2001-08-03 Miguel de Icaza <miguel@ximian.com>
1655 * rootcontext.cs: Provide better error reporting.
1657 * cs-parser.jay (interface_base): set our $$ to be interfaces.
1659 * rootcontext.cs (CreateInterface): Handle the case where there
1660 are no parent interfaces.
1662 (CloseTypes): Routine to flush types at the end.
1663 (CreateInterface): Track types.
1664 (GetInterfaces): Returns an array of Types from the list of
1667 * typemanager.c (AddUserType): Mechanism to track user types (puts
1668 the type on the global type hash, and allows us to close it at the
1671 2001-08-02 Miguel de Icaza <miguel@ximian.com>
1673 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
1674 RecordInterface instead.
1676 * cs-parser.jay: Updated to reflect changes above.
1678 * decl.cs (Definition): Keep track of the TypeBuilder type that
1679 represents this type here. Not sure we will use it in the long
1680 run, but wont hurt for now.
1682 * driver.cs: Smaller changes to accomodate the new code.
1684 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
1687 * rootcontext.cs (CreateInterface): New method, used to create
1688 the System.TypeBuilder type for interfaces.
1689 (ResolveInterfaces): new entry point to resolve the interface
1691 (CodeGen): Property, used to keep track of the code generator.
1693 2001-07-26 Miguel de Icaza <miguel@ximian.com>
1695 * cs-parser.jay: Add a second production for delegate_declaration
1698 (enum_body): Put an opt_comma here instead of putting it on
1699 enum_body or enum_member_declarations so we can handle trailing
1700 commas on enumeration members. Gets rid of a shift/reduce.
1702 (type_list): Need a COMMA in the middle.
1704 (indexer_declaration): Tell tokenizer to recognize get/set
1706 * Remove old targets.
1708 * Re-add the parser target.
1710 2001-07-13 Simon Cozens <simon@simon-cozens.org>
1712 * cs-parser.jay: Add precendence rules for a number of operators
1713 ot reduce the number of shift/reduce conflicts in the grammar.
1715 2001-07-17 Miguel de Icaza <miguel@ximian.com>
1717 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
1720 Get rid of old crufty code.
1722 * rootcontext.cs: Use this to keep track of the parsed
1723 representation and the defined types available to the program.
1725 * gen-treedump.cs: adjust for new convention.
1727 * type.cs: Split out the type manager, and the assembly builder
1730 * typemanager.cs: the type manager will live here now.
1732 * cil-codegen.cs: And the code generator here.
1734 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
1736 * makefile: Fixed up for easy making.
1738 2001-07-13 Simon Cozens <simon@simon-cozens.org>
1740 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
1743 (unary_expression): Expand pre_increment_expression and
1744 post_decrement_expression to reduce a shift/reduce.
1746 2001-07-11 Simon Cozens
1748 * cs-tokenizer.cs: Hex numbers should begin with a 0.
1750 Improve allow_keyword_as_indent name.
1752 2001-06-19 Miguel de Icaza <miguel@ximian.com>
1754 * Adjustments for Beta2.
1756 2001-06-13 Miguel de Icaza <miguel@ximian.com>
1758 * decl.cs: Added `Define' abstract method.
1759 (InTransit): new property, used to catch recursive definitions.
1761 * interface.cs: Implement `Define'.
1763 * modifiers.cs: Map Modifiers.constants to
1764 System.Reflection.TypeAttribute flags.
1766 * class.cs: Keep track of types and user-defined types.
1767 (BuilderInit): New method for creating an assembly
1768 (ResolveType): New function to launch the resolution process, only
1769 used by interfaces for now.
1771 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
1772 that are inserted into the name space.
1774 2001-06-08 Miguel de Icaza <miguel@ximian.com>
1776 * ARGH. I have screwed up my tree so many times due to the use of
1777 rsync rather than using CVS. Going to fix this at once.
1779 * driver.cs: Objetify driver. Load assemblies, use assemblies to
1782 2001-06-07 Miguel de Icaza <miguel@ximian.com>
1784 * Experiment successful: Use System.Type rather that our own
1787 2001-05-25 Miguel de Icaza <miguel@ximian.com>
1789 * cs-parser.jay: Removed nsAliases from here.
1791 Use new namespaces, handle `using XXX;'
1793 * namespace.cs: Reimplemented namespace handling, use a recursive
1794 definition of the class. Now we can keep track of using clauses
1795 and catch invalid using clauses.
1797 2001-05-24 Miguel de Icaza <miguel@ximian.com>
1799 * gen-treedump.cs: Adapted for all the renaming.
1801 * expression.cs (Expression): this class now has a Type property
1802 which returns an expression Type.
1804 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
1805 `Type', as this has a different meaning now in the base
1807 2001-05-22 Miguel de Icaza <miguel@ximian.com>
1809 * interface.cs, class.cs: Removed from all the sources the
1810 references to signature computation, as we can not do method
1811 signature computation during the parsing time, as we are not
1812 trying to solve at that point distinguishing:
1816 void a (NS.Blah x) {}
1819 Which depending on the context might be valid or not, as we do not
1820 know if Blah is the same thing as NS.Blah at that point.
1822 * Redid everything so the code uses TypeRefs now instead of
1823 Types. TypeRefs are just temporary type placeholders, that need
1824 to be resolved. They initially have a pointer to a string and the
1825 current scope in which they are used. This is used later by the
1826 compiler to resolve the reference to an actual Type.
1828 * DeclSpace is no longer a CIR.Type, and neither are
1829 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
1830 are all DeclSpaces, but no Types.
1832 * type.cs (TypeRefManager): This implements the TypeRef manager,
1833 which keeps track of all the types that need to be resolved after
1834 the parsing has finished.
1836 2001-05-13 Miguel de Icaza <miguel@ximian.com>
1838 * ARGH. We are going to have to store `foreach' as a class rather
1839 than resolving it, as we need to verify error 1579 after name
1840 resolution. *OR* we could keep a flag that says `This request to
1841 IEnumerator comes from a foreach statement' which we can then use
1842 to generate the error.
1844 2001-05-10 Miguel de Icaza <miguel@ximian.com>
1846 * class.cs (TypeContainer.AddMethod): we now add methods to the
1847 MethodGroup instead of the method hashtable.
1849 * expression.cs: Add MethodGroup abstraction, which gets us one
1850 step closer to the specification in the way we handle method
1853 * cs-parser.jay (primary_expression): qualified_identifier now
1854 tried to match up an identifier to a local variable reference or
1855 to a parameter reference.
1857 current_local_parameters is now a parser global variable that
1858 points to the current parameters for the block, used during name
1861 (property_declaration): Now creates an implicit `value' argument to
1864 2001-05-09 Miguel de Icaza <miguel@ximian.com>
1866 * parameter.cs: Do not use `param' arguments as part of the
1867 signature, per the spec.
1869 2001-05-08 Miguel de Icaza <miguel@ximian.com>
1871 * decl.cs: Base class for classes, structs and interfaces. This
1872 is the "Declaration Space"
1874 * cs-parser.jay: Use CheckDef for checking declaration errors
1875 instead of having one on each function.
1877 * class.cs: Factor out some code for handling error handling in
1878 accordance to the "Declarations" section in the "Basic Concepts"
1879 chapter in the ECMA C# spec.
1881 * interface.cs: Make all interface member classes derive from
1882 InterfaceMemberBase.
1884 2001-05-07 Miguel de Icaza <miguel@ximian.com>
1886 * Many things: all interfaces are parsed and generated in
1887 gen-treedump. Support for member variables, constructors,
1888 destructors, properties, constants is there.
1890 Beginning of the IL backend, but very little done, just there for
1893 2001-04-29 Miguel de Icaza <miguel@ximian.com>
1895 * cs-parser.jay: Fix labeled statement.
1897 * cs-tokenizer.cs (escape): Escape " and ' always.
1898 ref_line, ref_name: keep track of the line/filename as instructed
1899 by #line by the compiler.
1902 2001-04-27 Miguel de Icaza <miguel@ximian.com>
1904 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
1905 to match the values in System.CodeDOM.
1907 Divid renamed to Divide.
1909 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
1911 (Statements.set): remove.
1913 * System.CodeDOM/CodeCatchClause.cs: always have a valid
1916 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
1917 falseStatements always have valid values.
1919 * cs-parser.jay: Use System.CodeDOM now.
