1 2001-10-02 Ravi Pratap <ravi@ximian.com>
3 * expression.cs (Unary::ResolveOperator): Find operators on base type
4 too - we now conform exactly to the spec.
6 (Binary::ResolveOperator): Same here.
8 * class.cs (Operator::Define): Fix minor quirk in the tests.
10 * ../errors/cs0215.cs : Added.
12 * ../errors/cs0556.cs : Added.
14 * ../errors/cs0555.cs : Added.
16 2001-10-01 Miguel de Icaza <miguel@ximian.com>
18 * cs-tokenizer.cs: Reimplemented Location to be a struct with a
19 single integer which is really efficient
21 2001-10-01 Ravi Pratap <ravi@ximian.com>
23 * expression.cs (Expression::ImplicitUserConversion): Use location
24 even in the case when we are examining True operators.
26 * class.cs (Operator::Define): Perform extensive checks to conform
27 with the rules for operator overloading in the spec.
29 * expression.cs (Expression::ImplicitReferenceConversion): Implement
30 some of the other conversions mentioned in the spec.
32 * typemanager.cs (array_type): New static member for the System.Array built-in
35 (cloneable_interface): For System.ICloneable interface.
37 * driver.cs (Driver::Driver): Initialize TypeManager's core types even before
38 we start resolving the tree and populating types.
40 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
42 2001-10-01 Miguel de Icaza <miguel@ximian.com>
44 * expression.cs (Expression::ExprClassFromMemberInfo,
45 Expression::Literalize): Create literal expressions from
46 FieldInfos which are literals.
48 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
49 type casts, because they were wrong. The test suite in tests
52 (ImplicitNumericConversion): ushort to ulong requires a widening
55 Int32 constant to long requires widening cast as well.
57 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
58 for integers because the type on the stack is not i4.
60 2001-09-30 Miguel de Icaza <miguel@ximian.com>
62 * expression.cs (report118): require location argument.
64 * parameter.cs: Do not dereference potential null value.
66 * class.cs: Catch methods that lack the `new' keyword when
67 overriding a name. Report warnings when `new' is used without
68 anything being there to override.
70 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
72 * class.cs: Only add constructor to hashtable if it is non-null
73 (as now constructors can fail on define).
75 (TypeManager, Class, Struct): Take location arguments.
77 Catch field instance initialization in structs as errors.
79 accepting_filter: a new filter for FindMembers that is static so
80 that we dont create an instance per invocation.
82 (Constructor::Define): Catch errors where a struct constructor is
85 * cs-parser.jay: Pass location information for various new
88 * delegate.cs (Delegate): take a location argument.
90 * driver.cs: Do not call EmitCode if there were problesm in the
91 Definition of the types, as many Builders wont be there.
93 * decl.cs (Decl::Decl): Require a location argument.
95 * cs-tokenizer.cs: Handle properly hex constants that can not fit
96 into integers, and find the most appropiate integer for it.
98 * literal.cs: Implement ULongLiteral.
100 * rootcontext.cs: Provide better information about the location of
101 failure when CreateType fails.
103 2001-09-29 Miguel de Icaza <miguel@ximian.com>
105 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
108 * expression.cs (Binary::CheckShiftArguments): Add missing type
110 (Binary::ResolveOperator): Add type to the logical and and logical
111 or, Bitwise And/Or and Exclusive Or code paths, it was missing
114 (Binary::DoNumericPromotions): In the case where either argument
115 is ulong (and most signed types combined with ulong cause an
116 error) perform implicit integer constant conversions as well.
118 2001-09-28 Miguel de Icaza <miguel@ximian.com>
120 * expression.cs (UserImplicitCast): Method should always be
122 (Invocation::BetterConversion): Simplified test for IntLiteral.
124 (Expression::ImplicitNumericConversion): Split this routine out.
125 Put the code that performs implicit constant integer conversions
128 (Expression::Resolve): Become a wrapper around DoResolve so we can
129 check eclass and type being set after resolve.
131 (Invocation::Badness): Remove this dead function
133 (Binary::ResolveOperator): Do not compute the expensive argumnets
134 unless we have a union for it.
136 (Probe::Emit): Is needs to do an isinst and then
137 compare against null.
139 (::CanConvert): Added Location argument. If the Location argument
140 is null (Location.Null), then we do not report errors. This is
141 used by the `probe' mechanism of the Explicit conversion. We do
142 not want to generate an error for something that the user
143 explicitly requested to be casted. But the pipeline for an
144 explicit cast first tests for potential implicit casts.
146 So for now, if the Location is null, it means `Probe only' to
147 avoid adding another argument. Might have to revise this
150 (ClassCast): New class used to type cast objects into arbitrary
151 classes (used in Explicit Reference Conversions).
153 Implement `as' as well.
155 Reverted all the patches from Ravi below: they were broken:
157 * The use of `level' as a mechanism to stop recursive
158 invocations is wrong. That was there just to catch the
159 bug with a strack trace but not as a way of addressing
162 To fix the problem we have to *understand* what is going
163 on and the interactions and come up with a plan, not
164 just get things going.
166 * The use of the type conversion cache that I proposed
167 last night had an open topic: How does this work across
168 protection domains. A user defined conversion might not
169 be public in the location where we are applying the
170 conversion, a different conversion might be selected
171 (ie, private A->B (better) but public B->A (worse),
172 inside A, A->B applies, but outside it, B->A will
175 * On top of that (ie, even if the above is solved),
176 conversions in a cache need to be abstract. Ie, `To
177 convert from an Int to a Short use an OpcodeCast', not
178 `To convert from an Int to a Short use the OpcodeCast on
179 the variable 5' (which is what this patch was doing).
181 2001-09-28 Ravi Pratap <ravi@ximian.com>
183 * expression.cs (Invocation::ConversionExists): Re-write to use
186 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
187 cache all conversions done, not just user-defined ones.
189 (Invocation::BetterConversion): The real culprit. Use ConversionExists
190 to determine if a conversion exists instead of acutually trying to
191 perform the conversion. It's faster too.
193 (Expression::ConvertExplicit): Modify to use ConversionExists to check
194 and only then attempt the implicit conversion.
196 2001-09-28 Ravi Pratap <ravi@ximian.com>
198 * expression.cs (ConvertImplicit): Use a cache for conversions
199 already found. Check level of recursion and bail out if necessary.
201 2001-09-28 Miguel de Icaza <miguel@ximian.com>
203 * typemanager.cs (string_concat_string_string, string_concat_object_object):
204 Export standard methods that we expect for string operations.
206 * statement.cs (Block::UsageWarning): Track usage of variables and
207 report the errors for not used variables.
209 * expression.cs (Conditional::Resolve, ::Emit): Implement ?:
212 2001-09-27 Miguel de Icaza <miguel@ximian.com>
214 * codegen.cs: remove unnneded code
216 * expression.cs: Removed BuiltinTypeAccess class
218 Fix the order in which implicit conversions are
221 The previous fixed dropped support for boxed conversions (adding a
222 test to the test suite now)
224 (UserImplicitCast::CanConvert): Remove test for source being null,
225 that code is broken. We should not feed a null to begin with, if
226 we do, then we should track the bug where the problem originates
227 and not try to cover it up here.
229 Return a resolved expression of type UserImplicitCast on success
230 rather than true/false. Ravi: this is what I was talking about,
231 the pattern is to use a static method as a "constructor" for
234 Also, do not create arguments until the very last minute,
235 otherwise we always create the arguments even for lookups that
236 will never be performed.
238 (UserImplicitCast::Resolve): Eliminate, objects of type
239 UserImplicitCast are born in a fully resolved state.
241 * typemanager.cs (InitCoreTypes): Init also value_type
244 * expression.cs (Cast::Resolve): First resolve the child expression.
246 (LValue): Add new method AddressOf to be used by
249 Change the argument of Store to take an EmitContext instead of an
250 ILGenerator, because things like FieldExpr need to be able to call
251 their children expression to generate the instance code.
253 (Expression::Error, Expression::Warning): Sugar functions for
256 (Expression::MemberLookup): Accept a TypeContainer instead of a
257 Report as the first argument.
259 (Expression::ResolvePrimary): Killed. I still want to improve
260 this as currently the code is just not right.
262 (Expression::ResolveMemberAccess): Simplify, but it is still
265 (Unary::Resolve): Catch errors in AddressOf operators.
267 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
268 index to a byte for the short-version, or the compiler will choose
269 the wrong Emit call, which generates the wrong data.
271 (ParameterReference::Emit, ::Store): same.
273 (FieldExpr::AddressOf): Implement.
275 * typemanager.cs: TypeManager: made public variable instead of
278 * driver.cs: document --fatal.
280 * report.cs (ErrorMessage, WarningMessage): new names for the old
281 Error and Warning classes.
283 * cs-parser.jay (member_access): Turn built-in access to types
284 into a normal simplename
286 2001-09-27 Ravi Pratap <ravi@ximian.com>

302 * expression.cs (UserImplicitCast::CanConvert): Static method to do
303 the work of all the checking.
304 (ConvertImplicit): Call CanConvert and only then create object if necessary.
305 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
307 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
308 that is the right way.
310 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
311 overloading resolution. Use everywhere instead of cutting and pasting code.
313 (Binary::ResolveOperator): Use MakeUnionSet.
315 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
316 we have to convert to bool types. Not complete yet.
318 2001-09-27 Miguel de Icaza <miguel@ximian.com>
320 * typemanager.cs (TypeManager::CSharpName): support ushort.
322 * expression.cs (Expression::TryImplicitIntConversion): Attempts
323 to provide an expression that performsn an implicit constant int
324 conversion (section 6.1.6).
325 (Expression::ConvertImplicitRequired): Reworked to include
326 implicit constant expression conversions.
328 (Expression::ConvertNumericExplicit): Finished.
330 (Invocation::Emit): If InstanceExpression is null, then it means
331 that we perform a call on this.

335 * expression.cs (Unary::Emit): Remove some dead code.
336 (Probe): Implement Resolve and Emit for `is'.
337 (Expression::ConvertImplicitRequired): Attempt to do constant
338 expression conversions here. Maybe should be moved to
339 ConvertImplicit, but I am not sure.
340 (Expression::ImplicitLongConstantConversionPossible,
341 Expression::ImplicitIntConstantConversionPossible): New functions
342 that tell whether is it possible to apply an implicit constant
343 expression conversion.

355 * class.cs (Operator): Update the operator names to reflect the
356 ones that the spec expects (as we are just stringizing the
359 * expression.cs (Unary::ResolveOperator): Fix bug: Use
360 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
361 previous usage did only work for our methods.
362 (Expression::ConvertImplicit): Handle decimal implicit numeric
364 (Expression::InternalTypeConstructor): Used to invoke constructors
365 on internal types for default promotions.
367 (Unary::Emit): Implement special handling for the pre/post
368 increment/decrement for overloaded operators, as they need to have
369 the same semantics as the other operators.
371 (Binary::ResolveOperator): ditto.
372 (Invocation::ConversionExists): ditto.
373 (UserImplicitCast::Resolve): ditto.
375 2001-09-26 Ravi Pratap <ravi@ximian.com>

389 * assign.cs (Assign): Make it inherit from ExpressionStatement.
391 * expression.cs (ExpressionStatement): New base class used for
392 expressions that can appear in statements, so that we can provide
393 an alternate path to generate expression that do not leave a value
396 (Expression::Emit, and all the derivatives): We no longer return
397 whether a value is left on the stack or not. Every expression
398 after being emitted leaves a single value on the stack.
400 * codegen.cs (EmitContext::EmitStatementExpression): Use the
401 facilties of ExpressionStatement if possible.

428 * assign.cs: track location.
429 (Resolve): Use implicit conversions on assignment.
431 * literal.cs: Oops. Not good, Emit of short access values should

494 * typemanager.cs: declare and load enum_type, delegate_type and
497 * expression.cs (Expression::Emit): Now emit returns a value that
498 tells whether a value is left on the stack or not. This strategy
499 might be reveted tomorrow with a mechanism that would address
500 multiple assignments.
501 (Expression::report118): Utility routine to report mismatches on
504 (Unary::Report23): Report impossible type/operator combination
507 (Unary::IsIncrementableNumber): Whether the type can be

513 (Invocation::Emit): Deal with new Emit convetion.
515 * All Expression derivatives: Updated their Emit method to return
516 whether they leave values on the stack or not.
518 * codegen.cs (CodeGen::EmitStatement): Pop values left on the
519 stack for expressions that are statements.
521 2001-09-20 Miguel de Icaza <miguel@ximian.com>
523 * expression.cs (LValue): New interface. Must be implemented by

558 * codegen.cs (CodeGen::Save, CodeGen::CodeGen, CodeGen::Basename):
559 Use a basename for those routines because .NET does not like paths

572 expression for expressions which are just +expr.

597 (Binary::ResolveOperator): Re-write bits to quietly continue if no overloaded

600 Binary::ResolveOperator does for Binary expressions.
601 (Unary.method, .Arguments): Add.
602 (Unary::OperName): Implement.
603 (Unary::ForceConversion): Copy and Paste !
605 * class.cs (Operator::Define): Fix a small bug for the case when we have
608 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
609 for the inbuilt operators. Only overloading works for now ;-)
611 2001-09-18 Miguel de Icaza <miguel@ximian.com>

629 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
630 the last instruction contains a return opcode to avoid generating
631 the last `ret' instruction (this generates correct code, and it is
632 nice to pass the peverify output).
634 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
635 initializer for static and instance variables.
636 (Constructor::Emit): Allow initializer to be null in the case of
637 static constructors. Only emit initializer for instance
640 (TypeContainer::FindMembers): Return a null array if there are no

650 * driver.cs: Stop compilation if there are parse errors.
652 * cs-parser.jay (constructor_declaration): Provide default base
653 initializer for non-static constructors.

655 initializers if none was specified.
656 Catch the fact that constructors should not have parameters.
658 * class.cs: Do not emit parent class initializers for static
659 constructors, that should be flagged as an error.
661 2001-09-18 Ravi Pratap <ravi@ximian.com>
663 * class.cs (RegisterMethodBuilder): Remove : it's unnecessary.
664 Move back code into TypeContainer::Populate.

686 just not able to get it right !
688 2001-09-17 Miguel de Icaza <miguel@ximian.com>
690 * expression.cs (Expression::OverloadResolve): Drop TypeContainer
693 (Expression::MemberLookup): Provide a version that allows to
694 specify the MemberTypes and BindingFlags.
696 * statement.cs (Block::GetVariableInfo): Forgot to recurse here,
697 so it was not fetching variable information from outer blocks.

700 Beforefieldinit as it was buggy.
702 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200
705 * class.cs (Constructor::Emit): Only emit if block is not null.
706 (TypeContainer::EmitDefaultConstructor): Removed routine, now we
707 deal with this by semantically definining it as if the user had
710 (TypeContainer::FindMembers): Removed ad-hoc hack to deal with
711 constructors as we now "emit" them at a higher level.

731 2001-09-17 Ravi Pratap <ravi@ximian.com>
733 * rootcontext.cs (IsNameSpace): Compare against null.
735 * everywhere : Correct spelling to 'Greater' and to 'Subtract'

744 we have overloaded operators.
745 (Binary::ResolveOperator): Implement the part which does the operator overload

756 * rootcontext.cs: Fix bug: tree.Namespaces might be null.
758 2001-09-16 Ravi Pratap <ravi@ximian.com>

800 container to evaluate permission settings.
802 * class.cs: Put Ravi's patch back in. He is right, and we will
803 have to cope with the
805 2001-09-14 Ravi Pratap <ravi@ximian.com>
807 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to

812 * driver.cs: Added --parse option that only parses its input files
815 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
816 incorrect. IsTopLevel is not used to tell whether an object is
817 root_types or not (that can be achieved by testing this ==
818 root_types). But to see if this is a top-level *class* (not
819 necessarly our "toplevel" container).
821 2001-09-14 Ravi Pratap <ravi@ximian.com>
823 * enum.cs (Enum::Define): Modify to call the Lookup method on the
824 parent instead of a direct call to GetType.
826 2001-09-14 Ravi Pratap <ravi@ximian.com>
828 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
829 Modifiers.TypeAttr. This should just be a call to that method.

845 * modifiers.cs (MethodAttr): Re-write.
846 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
848 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
849 of top-level types as claimed.
851 2001-09-13 Miguel de Icaza <miguel@ximian.com>
853 * expression.cs (MemberLookup): Fruitless attempt to lookup
854 constructors. Maybe I need to emit default constructors? That

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

891 (Binary::ResolveOperator): Set the return type to boolean for
892 comparission operators
894 * typemanager.cs: Remove debugging print code.
896 (Invocation::Resolve): resolve type.
898 * class.cs: Allocate a MemberInfo of the correct size, as the code
899 elsewhere depends on the test to reflect the correct contents.
901 (Method::) Keep track of parameters, due to System.Reflection holes
903 (TypeContainer::Populate): Keep track of MethodBuilders to Method
906 (TypeContainer::FindMembers): Use ArrayList and then copy an array
907 of the exact size and return that.
909 (Class::LookupMethodByBuilder): New function that maps
910 MethodBuilders to its methods. Required to locate the information
911 on methods because System.Reflection bit us again.
913 * support.cs: New file, contains an interface ParameterData and
914 two implementations: ReflectionParameters and InternalParameters
915 used to access Parameter information. We will need to grow this
918 * expression.cs (Invocation::GetParameterData): implement a cache
919 and a wrapper around the ParameterData creation for methods.
920 (Invocation::OverloadResolve): Use new code.
922 2001-09-13 Ravi Pratap <ravi@ximian.com>

1026 addOn_ and removeOn_
1028 * genericparser.cs (GenericParser::error): Overloaded method to handle the case
1029 of the location being passed in too. Ideally, this should go later since all
1030 error reporting should be done through the Report object.
1032 * class.cs (TypeContainer.Indexers): New property to access the list of indexers.
1033 (Populate): Iterate thru the indexers we have and define them too.

1362 the Define method of the Property class.
1364 * class.cs : Clean up applied patch and update references to variables etc. Fix
1366 (TypeContainer::Populate): Update to define all the properties we have. Also
1367 define all enumerations.
1369 * enum.cs (Define): Implement.
1371 2001-08-31 Ravi Pratap <ravi@che.iitm.ac.in>
1373 * cs-parser.jay (overloadable_operator): The semantic value is an
1374 enum of the Operator class.
1375 (operator_declarator): Implement actions.
1376 (operator_declaration): Implement.
1378 * class.cs (Operator::CheckUnaryOperator): New static method to help in checking
1379 validity of definitions.
1380 (Operator::CheckBinaryOperator): Static method to check for binary operators
1381 (TypeContainer::AddOperator): New method to add an operator to a type.
1383 * cs-parser.jay (indexer_declaration): Added line to actually call the
1384 AddIndexer method so it gets added ;-)
1386 * ../errors/errors.txt : Update to include new error numbers. Are these numbers
1387 already taken care of by the MS compiler ?
1389 2001-08-29 Ravi Pratap <ravi@che.iitm.ac.in>
1391 * class.cs (Operator): New class for operator declarations.
1392 (Operator::OpType): Enum for the various operators.
1394 2001-08-29 Ravi Pratap <ravi@che.iitm.ac.in>
1396 * class.cs (TypeContainer::AddIndexer): Remove FIXME comment. We

1399 * cs-parser.jay (general_catch_clause): Comment out
1400 (specific_catch_clauses, specific_catch_clause): Ditto.
1401 (opt_general_catch_clause, opt_specific_catch_clauses): Ditto

1403 (catch_clause): Rewrite to use the new productions above
1404 (catch_clauses): Modify accordingly.
1405 (opt_catch_clauses): New production to use in try_statement
1406 (try_statement): Revamp. Basically, we get rid of one unnecessary rule
1407 and re-write the code in the actions to extract the specific and
1408 general catch clauses by being a little smart ;-)
1410 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
1411 Hooray, try and catch statements parse fine !
1413 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
1415 * statement.cs (Block::GetVariableType): Fix logic to extract the type
1416 string from the hashtable of variables.
1418 * cs-parser.jay (event_accessor_declarations): Trivial fix. Man, how did
1419 I end up making that mistake ;-)
1420 (catch_clauses): Fixed gross error which made Key and Value of the
1421 DictionaryEntry the same : $1 !!
1423 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
1425 * cs-tokenizer.cs (initTokens): Add keywords 'add' and 'remove'
1427 * cs-parser.jay (event_declaration): Correct to remove the semicolon
1428 when the add and remove accessors are specified.
1430 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
1432 * cs-parser.jay (IndexerDeclaration): New helper class to hold
1433 information about indexer_declarator.
1434 (indexer_declarator): Implement actions.
1435 (parsing_indexer): New local boolean used to keep track of whether
1436 we are parsing indexers or properties. This is necessary because
1437 implicit_parameters come into picture even for the get accessor in the
1439 (get_accessor_declaration, set_accessor_declaration): Correspondingly modified.
1441 * class.cs (Indexer): New class for indexer declarations.
1442 (TypeContainer::AddIndexer): New method to add an indexer to a type.
1443 (TypeContainer::indexers): New member to hold list of indexers for the
1446 2001-08-27 Ravi Pratap <ravi@che.iitm.ac.in>
1448 * cs-parser.jay (add_accessor_declaration): Implement action.
1449 (remove_accessor_declaration): Implement action.
1450 (event_accessors_declaration): Implement

1453 * class.cs (Event): New class to hold information about event
1455 (TypeContainer::AddEvent): New method to add an event to a type
1456 (TypeContainer::events): New member to hold list of events.
1458 * cs-parser.jay (event_declaration): Implement actions.
1460 2001-08-27 Ravi Pratap <ravi@che.iitm.ac.in>
1462 * cs-parser.jay (dim_separators): Implement. Make it a string
1463 concatenating all the commas together, just as they appear.
1464 (opt_dim_separators): Modify accordingly
1465 (rank_specifiers): Update accordingly. Basically do the same
1466 thing - instead, collect the brackets here.
1467 (opt_rank_sepcifiers): Modify accordingly.
1468 (array_type): Modify to actually return the complete type string
1469 instead of ignoring the rank_specifiers.
1470 (expression_list): Implement to collect the expressions
1471 (variable_initializer): Implement. We make it a list of expressions
1472 essentially so that we can handle the array_initializer case neatly too.
1473 (variable_initializer_list): Implement.
1474 (array_initializer): Make it a list of variable_initializers
1475 (opt_array_initializer): Modify accordingly.
1477 * expression.cs (New::NType): Add enumeration to help us
1478 keep track of whether we have an object/delegate creation
1479 or an array creation.
1480 (New:NewType, New::Rank, New::Indices, New::Initializers): New
1481 members to hold data about array creation.
1482 (New:New): Modify to update NewType
1483 (New:New): New Overloaded contructor for the array creation
1486 * cs-parser.jay (array_creation_expression): Implement to call
1487 the overloaded New constructor.
1489 2001-08-26 Ravi Pratap <ravi@che.iitm.ac.in>
1491 * class.cs (TypeContainer::Constructors): Return member
1492 constructors instead of returning null.
1494 2001-08-26 Miguel de Icaza <miguel@ximian.com>
1496 * typemanager.cs (InitCoreTypes): Initialize the various core
1497 types after we have populated the type manager with the user
1498 defined types (this distinction will be important later while
1499 compiling corlib.dll)
1501 * expression.cs, literal.cs, assign.cs, constant.cs: Started work
1502 on Expression Classification. Now all expressions have a method
1503 `Resolve' and a method `Emit'.
1505 * codegen.cs, cs-parser.jay: Fixed the bug that stopped code
1506 generation from working. Also add some temporary debugging
1509 2001-08-24 Miguel de Icaza <miguel@ximian.com>
1511 * codegen.cs: Lots of code generation pieces. This is only the
1512 beginning, will continue tomorrow with more touches of polish. We
1513 handle the fundamentals of if, while, do, for, return. Others are
1514 trickier and I need to start working on invocations soon.
1516 * gen-treedump.cs: Bug fix, use s.Increment here instead of
1519 * codegen.cs (EmitContext): New struct, used during code
1520 emission to keep a context. Most of the code generation will be
1523 * cs-parser.jay: Add embedded blocks to the list of statements of
1524 this block. So code generation proceeds in a top down fashion.
1526 2001-08-23 Miguel de Icaza <miguel@ximian.com>
1528 * statement.cs: Add support for multiple child blocks.
1530 2001-08-22 Miguel de Icaza <miguel@ximian.com>
1532 * codegen.cs (EmitCode): New function, will emit the code for a
1533 Block of code given a TypeContainer and its ILGenerator.
1535 * statement.cs (Block): Standard public readonly optimization.
1536 (Block::Block constructors): Link children.
1537 (Block::Child): Child Linker.
1538 (Block::EmitVariables): Emits IL variable declarations.
1540 * class.cs: Drop support for MethodGroups here, delay until
1542 (Method::): Applied the same simplification that I did before, and
1543 move from Properties to public readonly fields.
1544 (Method::ParameterTypes): Returns the parameter types for the
1545 function, and implements a cache that will be useful later when I
1546 do error checking and the semantic analysis on the methods is
1548 (Constructor::GetCallingConvention): Renamed from CallingConvetion
1549 and made a method, optional argument tells whether this is a class
1550 or a structure to apply the `has-this' bit.
1551 (Method::GetCallingConvention): Implement, returns the calling
1553 (Method::Define): Defines the type, a second pass is performed
1554 later to populate the methods.
1556 (Constructor::ParameterTypes): implement a cache similar to the
1557 one on Method::ParameterTypes, useful later when we do semantic
1560 (TypeContainer::EmitMethod): New method. Emits methods.
1562 * expression.cs: Removed MethodGroup class from here.
1564 * parameter.cs (Parameters::GetCallingConvention): new method.

1571 (Constructor::CallingConvention): Returns the calling convention.
1572 (Constructor::ParameterTypes): Returns the constructor parameter
1575 (TypeContainer::AddConstructor): Keep track of default constructor
1576 and the default static constructor.
1578 (Constructor::) Another class that starts using `public readonly'
1579 instead of properties.
1581 (Constructor::IsDefault): Whether this is a default constructor.
1583 (Field::) use readonly public fields instead of properties also.
1585 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
1586 track of static constructors; If none is used, turn on
1587 BeforeFieldInit in the TypeAttributes.
1589 * cs-parser.jay (opt_argument_list): now the return can be null
1590 for the cases where there are no arguments.
1592 (constructor_declarator): If there is no implicit `base' or
1593 `this', then invoke the default parent constructor.
1595 * modifiers.cs (MethodAttr): New static function maps a set of
1596 modifiers flags into a MethodAttributes enum
1597 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
1598 MethodAttr, TypeAttr to represent the various mappings where the
1600 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
1602 2001-08-19 Miguel de Icaza <miguel@ximian.com>
1604 * parameter.cs (GetParameterInfo): Fix bug where there would be no
1607 * interface.cs (PopulateIndexer): Implemented the code generator
1608 for interface indexers.
1610 2001-08-17 Miguel de Icaza <miguel@ximian.com>
1612 * interface.cs (InterfaceMemberBase): Now we track the new status
1615 (PopulateProperty): Implement property population. Woohoo! Got
1616 Methods and Properties going today.
1618 Removed all the properties for interfaces, and replaced them with
1619 `public readonly' fields.
1621 2001-08-16 Miguel de Icaza <miguel@ximian.com>
1623 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
1624 initialize their hashtables/arraylists only when they are needed
1625 instead of doing this always.
1627 * parameter.cs: Handle refs and out parameters.
1629 * cs-parser.jay: Use an ArrayList to construct the arguments
1630 instead of the ParameterCollection, and then cast that to a
1633 * parameter.cs: Drop the use of ParameterCollection and use
1634 instead arrays of Parameters.
1636 (GetParameterInfo): Use the Type, not the Name when resolving
1639 2001-08-13 Miguel de Icaza <miguel@ximian.com>
1641 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
1642 and instead use public readonly fields.
1644 * class.cs: Put back walking code for type containers.
1646 2001-08-11 Miguel de Icaza <miguel@ximian.com>
1648 * class.cs (MakeConstant): Code to define constants.
1650 * rootcontext.cs (LookupType): New function. Used to locate types
1653 2001-08-08 Miguel de Icaza <miguel@ximian.com>
1655 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
1656 this System.Reflection code is. Kudos to Microsoft
1658 * typemanager.cs: Implement a type cache and avoid loading all
1659 types at boot time. Wrap in LookupType the internals. This made
1660 the compiler so much faster. Wow. I rule!
1662 * driver.cs: Make sure we always load mscorlib first (for
1663 debugging purposes, nothing really important).
1665 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
1666 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
1668 * rootcontext.cs: Lookup types on their namespace; Lookup types
1669 on namespaces that have been imported using the `using' keyword.
1671 * class.cs (TypeContainer::TypeAttr): Virtualize.
1672 (Class::TypeAttr): Return attributes suitable for this bad boy.
1673 (Struct::TypeAttr): ditto.
1674 Handle nested classes.
1675 (TypeContainer::) Remove all the type visiting code, it is now
1676 replaced with the rootcontext.cs code
1678 * rootcontext.cs (GetClassBases): Added support for structs.
1680 2001-08-06 Miguel de Icaza <miguel@ximian.com>
1682 * interface.cs, statement.cs, class.cs, parameter.cs,
1683 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
1684 Drop use of TypeRefs, and use strings instead.
1686 2001-08-04 Miguel de Icaza <miguel@ximian.com>
1690 * class.cs (Struct::Struct): set the SEALED flags after
1691 checking the modifiers.
1692 (TypeContainer::TypeAttr): new property, returns the
1693 TypeAttributes for a class.
1695 * cs-parser.jay (type_list): Oops, list production was creating a
1696 new list of base types.
1698 * rootcontext.cs (StdLib): New property.
1699 (GetInterfaceTypeByName): returns an interface by type name, and
1700 encapsulates error handling here.
1701 (GetInterfaces): simplified.
1702 (ResolveTree): Encapsulated all the tree resolution here.
1703 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
1706 * driver.cs: Add support for --nostdlib, to avoid loading the
1708 (Main): Do not put tree resolution here.
1710 * rootcontext.cs: Beginning of the class resolution.
1712 2001-08-03 Miguel de Icaza <miguel@ximian.com>
1714 * rootcontext.cs: Provide better error reporting.
1716 * cs-parser.jay (interface_base): set our $$ to be interfaces.
1718 * rootcontext.cs (CreateInterface): Handle the case where there
1719 are no parent interfaces.
1721 (CloseTypes): Routine to flush types at the end.
1722 (CreateInterface): Track types.
1723 (GetInterfaces): Returns an array of Types from the list of
1726 * typemanager.c (AddUserType): Mechanism to track user types (puts
1727 the type on the global type hash, and allows us to close it at the
1730 2001-08-02 Miguel de Icaza <miguel@ximian.com>
1732 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
1733 RecordInterface instead.
1735 * cs-parser.jay: Updated to reflect changes above.
1737 * decl.cs (Definition): Keep track of the TypeBuilder type that
1738 represents this type here. Not sure we will use it in the long
1739 run, but wont hurt for now.
1741 * driver.cs: Smaller changes to accomodate the new code.
1743 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
1746 * rootcontext.cs (CreateInterface): New method, used to create
1747 the System.TypeBuilder type for interfaces.
1748 (ResolveInterfaces): new entry point to resolve the interface
1750 (CodeGen): Property, used to keep track of the code generator.
1752 2001-07-26 Miguel de Icaza <miguel@ximian.com>
1754 * cs-parser.jay: Add a second production for delegate_declaration
1757 (enum_body): Put an opt_comma here instead of putting it on
1758 enum_body or enum_member_declarations so we can handle trailing
1759 commas on enumeration members. Gets rid of a shift/reduce.
1761 (type_list): Need a COMMA in the middle.
1763 (indexer_declaration): Tell tokenizer to recognize get/set
1765 * Remove old targets.
1767 * Re-add the parser target.
1769 2001-07-13 Simon Cozens <simon@simon-cozens.org>
1771 * cs-parser.jay: Add precendence rules for a number of operators
1772 ot reduce the number of shift/reduce conflicts in the grammar.
1774 2001-07-17 Miguel de Icaza <miguel@ximian.com>
1776 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
1779 Get rid of old crufty code.
1781 * rootcontext.cs: Use this to keep track of the parsed
1782 representation and the defined types available to the program.
1784 * gen-treedump.cs: adjust for new convention.
1786 * type.cs: Split out the type manager, and the assembly builder
1789 * typemanager.cs: the type manager will live here now.
1791 * cil-codegen.cs: And the code generator here.

1795 * makefile: Fixed up for easy making.
1797 2001-07-13 Simon Cozens <simon@simon-cozens.org>
1799 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
1802 (unary_expression): Expand pre_increment_expression and
1803 post_decrement_expression to reduce a shift/reduce.

1807 * cs-tokenizer.cs: Hex numbers should begin with a 0.
1809 Improve allow_keyword_as_indent name.
1811 2001-06-19 Miguel de Icaza <miguel@ximian.com>
1813 * Adjustments for Beta2.
1815 2001-06-13 Miguel de Icaza <miguel@ximian.com>
1817 * decl.cs: Added `Define' abstract method.
1818 (InTransit): new property, used to catch recursive definitions.
1820 * interface.cs: Implement `Define'.
1822 * modifiers.cs: Map Modifiers.constants to
1823 System.Reflection.TypeAttribute flags.
1825 * class.cs: Keep track of types and user-defined types.
1826 (BuilderInit): New method for creating an assembly
1827 (ResolveType): New function to launch the resolution process, only
1828 used by interfaces for now.
1830 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
1831 that are inserted into the name space.
1833 2001-06-08 Miguel de Icaza <miguel@ximian.com>
1835 * ARGH. I have screwed up my tree so many times due to the use of
1836 rsync rather than using CVS. Going to fix this at once.
1838 * driver.cs: Objetify driver. Load assemblies, use assemblies to
1841 2001-06-07 Miguel de Icaza <miguel@ximian.com>
1843 * Experiment successful: Use System.Type rather that our own
1846 2001-05-25 Miguel de Icaza <miguel@ximian.com>
1848 * cs-parser.jay: Removed nsAliases from here.
1850 Use new namespaces, handle `using XXX;'
1852 * namespace.cs: Reimplemented namespace handling, use a recursive
1853 definition of the class. Now we can keep track of using clauses
1854 and catch invalid using clauses.
1856 2001-05-24 Miguel de Icaza <miguel@ximian.com>
1858 * gen-treedump.cs: Adapted for all the renaming.
1860 * expression.cs (Expression): this class now has a Type property
1861 which returns an expression Type.
1863 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
1864 `Type', as this has a different meaning now in the base
1866 2001-05-22 Miguel de Icaza <miguel@ximian.com>
1868 * interface.cs, class.cs: Removed from all the sources the
1869 references to signature computation, as we can not do method
1870 signature computation during the parsing time, as we are not
1871 trying to solve at that point distinguishing:
1875 void a (NS.Blah x) {}
1878 Which depending on the context might be valid or not, as we do not
1879 know if Blah is the same thing as NS.Blah at that point.
1881 * Redid everything so the code uses TypeRefs now instead of
1882 Types. TypeRefs are just temporary type placeholders, that need
1883 to be resolved. They initially have a pointer to a string and the
1884 current scope in which they are used. This is used later by the
1885 compiler to resolve the reference to an actual Type.
1887 * DeclSpace is no longer a CIR.Type, and neither are
1888 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
1889 are all DeclSpaces, but no Types.
1891 * type.cs (TypeRefManager): This implements the TypeRef manager,
1892 which keeps track of all the types that need to be resolved after
1893 the parsing has finished.
1895 2001-05-13 Miguel de Icaza <miguel@ximian.com>
1897 * ARGH. We are going to have to store `foreach' as a class rather
1898 than resolving it, as we need to verify error 1579 after name
1899 resolution. *OR* we could keep a flag that says `This request to
1900 IEnumerator comes from a foreach statement' which we can then use
1901 to generate the error.
1903 2001-05-10 Miguel de Icaza <miguel@ximian.com>
1905 * class.cs (TypeContainer.AddMethod): we now add methods to the
1906 MethodGroup instead of the method hashtable.
1908 * expression.cs: Add MethodGroup abstraction, which gets us one
1909 step closer to the specification in the way we handle method
1912 * cs-parser.jay (primary_expression): qualified_identifier now
1913 tried to match up an identifier to a local variable reference or
1914 to a parameter reference.
1916 current_local_parameters is now a parser global variable that
1917 points to the current parameters for the block, used during name
1920 (property_declaration): Now creates an implicit `value' argument to
1923 2001-05-09 Miguel de Icaza <miguel@ximian.com>
1925 * parameter.cs: Do not use `param' arguments as part of the
1926 signature, per the spec.
1928 2001-05-08 Miguel de Icaza <miguel@ximian.com>
1930 * decl.cs: Base class for classes, structs and interfaces. This
1931 is the "Declaration Space"
1933 * cs-parser.jay: Use CheckDef for checking declaration errors
1934 instead of having one on each function.
1936 * class.cs: Factor out some code for handling error handling in
1937 accordance to the "Declarations" section in the "Basic Concepts"
1938 chapter in the ECMA C# spec.
1940 * interface.cs: Make all interface member classes derive from
1941 InterfaceMemberBase.
1943 2001-05-07 Miguel de Icaza <miguel@ximian.com>
1945 * Many things: all interfaces are parsed and generated in
1946 gen-treedump. Support for member variables, constructors,
1947 destructors, properties, constants is there.
1949 Beginning of the IL backend, but very little done, just there for
1952 2001-04-29 Miguel de Icaza <miguel@ximian.com>
1954 * cs-parser.jay: Fix labeled statement.
1956 * cs-tokenizer.cs (escape): Escape " and ' always.
1957 ref_line, ref_name: keep track of the line/filename as instructed
1958 by #line by the compiler.
1961 2001-04-27 Miguel de Icaza <miguel@ximian.com>
1963 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
1964 to match the values in System.CodeDOM.
1966 Divid renamed to Divide.
1968 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
1970 (Statements.set): remove.
1972 * System.CodeDOM/CodeCatchClause.cs: always have a valid
1975 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
1976 falseStatements always have valid values.
1978 * cs-parser.jay: Use System.CodeDOM now.
