9 2001-10-02 Ravi Pratap <ravi@ximian.com>
11 * expression.cs (Unary::ResolveOperator): Find operators on base type
12 too - we now conform exactly to the spec.
14 (Binary::ResolveOperator): Same here.
16 * class.cs (Operator::Define): Fix minor quirk in the tests.
18 * ../errors/cs0215.cs : Added.
20 * ../errors/cs0556.cs : Added.
22 * ../errors/cs0555.cs : Added.
24 2001-10-01 Miguel de Icaza <miguel@ximian.com>
26 * cs-tokenizer.cs: Reimplemented Location to be a struct with a
27 single integer which is really efficient
29 2001-10-01 Ravi Pratap <ravi@ximian.com>
31 * expression.cs (Expression::ImplicitUserConversion): Use location
32 even in the case when we are examining True operators.
34 * class.cs (Operator::Define): Perform extensive checks to conform
35 with the rules for operator overloading in the spec.
37 * expression.cs (Expression::ImplicitReferenceConversion): Implement
38 some of the other conversions mentioned in the spec.
40 * typemanager.cs (array_type): New static member for the System.Array built-in
43 (cloneable_interface): For System.ICloneable interface.
45 * driver.cs (Driver::Driver): Initialize TypeManager's core types even before
46 we start resolving the tree and populating types.
48 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
50 2001-10-01 Miguel de Icaza <miguel@ximian.com>
52 * expression.cs (Expression::ExprClassFromMemberInfo,
53 Expression::Literalize): Create literal expressions from
54 FieldInfos which are literals.
56 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
57 type casts, because they were wrong. The test suite in tests
60 (ImplicitNumericConversion): ushort to ulong requires a widening
63 Int32 constant to long requires widening cast as well.
65 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
66 for integers because the type on the stack is not i4.
68 2001-09-30 Miguel de Icaza <miguel@ximian.com>
70 * expression.cs (report118): require location argument.
72 * parameter.cs: Do not dereference potential null value.
74 * class.cs: Catch methods that lack the `new' keyword when
75 overriding a name. Report warnings when `new' is used without
76 anything being there to override.
78 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
80 * class.cs: Only add constructor to hashtable if it is non-null
81 (as now constructors can fail on define).
83 (TypeManager, Class, Struct): Take location arguments.
85 Catch field instance initialization in structs as errors.
87 accepting_filter: a new filter for FindMembers that is static so
88 that we dont create an instance per invocation.
90 (Constructor::Define): Catch errors where a struct constructor is
93 * cs-parser.jay: Pass location information for various new
96 * delegate.cs (Delegate): take a location argument.
98 * driver.cs: Do not call EmitCode if there were problesm in the
99 Definition of the types, as many Builders wont be there.
101 * decl.cs (Decl::Decl): Require a location argument.
103 * cs-tokenizer.cs: Handle properly hex constants that can not fit
104 into integers, and find the most appropiate integer for it.
106 * literal.cs: Implement ULongLiteral.
108 * rootcontext.cs: Provide better information about the location of
109 failure when CreateType fails.
111 2001-09-29 Miguel de Icaza <miguel@ximian.com>
113 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
116 * expression.cs (Binary::CheckShiftArguments): Add missing type
118 (Binary::ResolveOperator): Add type to the logical and and logical
119 or, Bitwise And/Or and Exclusive Or code paths, it was missing
122 (Binary::DoNumericPromotions): In the case where either argument
123 is ulong (and most signed types combined with ulong cause an
124 error) perform implicit integer constant conversions as well.
126 2001-09-28 Miguel de Icaza <miguel@ximian.com>
128 * expression.cs (UserImplicitCast): Method should always be
130 (Invocation::BetterConversion): Simplified test for IntLiteral.
132 (Expression::ImplicitNumericConversion): Split this routine out.
133 Put the code that performs implicit constant integer conversions
136 (Expression::Resolve): Become a wrapper around DoResolve so we can
137 check eclass and type being set after resolve.
139 (Invocation::Badness): Remove this dead function
141 (Binary::ResolveOperator): Do not compute the expensive argumnets
142 unless we have a union for it.
144 (Probe::Emit): Is needs to do an isinst and then
145 compare against null.
147 (::CanConvert): Added Location argument. If the Location argument
148 is null (Location.Null), then we do not report errors. This is
149 used by the `probe' mechanism of the Explicit conversion. We do
150 not want to generate an error for something that the user
151 explicitly requested to be casted. But the pipeline for an
152 explicit cast first tests for potential implicit casts.
154 So for now, if the Location is null, it means `Probe only' to
155 avoid adding another argument. Might have to revise this
158 (ClassCast): New class used to type cast objects into arbitrary
159 classes (used in Explicit Reference Conversions).
161 Implement `as' as well.
163 Reverted all the patches from Ravi below: they were broken:
165 * The use of `level' as a mechanism to stop recursive
166 invocations is wrong. That was there just to catch the
167 bug with a strack trace but not as a way of addressing
170 To fix the problem we have to *understand* what is going
171 on and the interactions and come up with a plan, not
172 just get things going.
174 * The use of the type conversion cache that I proposed
175 last night had an open topic: How does this work across
176 protection domains. A user defined conversion might not
177 be public in the location where we are applying the
178 conversion, a different conversion might be selected
179 (ie, private A->B (better) but public B->A (worse),
180 inside A, A->B applies, but outside it, B->A will
183 * On top of that (ie, even if the above is solved),
184 conversions in a cache need to be abstract. Ie, `To
185 convert from an Int to a Short use an OpcodeCast', not
186 `To convert from an Int to a Short use the OpcodeCast on
187 the variable 5' (which is what this patch was doing).
189 2001-09-28 Ravi Pratap <ravi@ximian.com>
191 * expression.cs (Invocation::ConversionExists): Re-write to use
194 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
195 cache all conversions done, not just user-defined ones.
197 (Invocation::BetterConversion): The real culprit. Use ConversionExists
198 to determine if a conversion exists instead of acutually trying to
199 perform the conversion. It's faster too.
201 (Expression::ConvertExplicit): Modify to use ConversionExists to check
202 and only then attempt the implicit conversion.
204 2001-09-28 Ravi Pratap <ravi@ximian.com>
206 * expression.cs (ConvertImplicit): Use a cache for conversions
207 already found. Check level of recursion and bail out if necessary.
209 2001-09-28 Miguel de Icaza <miguel@ximian.com>
211 * typemanager.cs (string_concat_string_string, string_concat_object_object):
212 Export standard methods that we expect for string operations.
214 * statement.cs (Block::UsageWarning): Track usage of variables and
215 report the errors for not used variables.
217 * expression.cs (Conditional::Resolve, ::Emit): Implement ?:
220 2001-09-27 Miguel de Icaza <miguel@ximian.com>
222 * codegen.cs: remove unnneded code
224 * expression.cs: Removed BuiltinTypeAccess class
226 Fix the order in which implicit conversions are
229 The previous fixed dropped support for boxed conversions (adding a
230 test to the test suite now)
232 (UserImplicitCast::CanConvert): Remove test for source being null,
233 that code is broken. We should not feed a null to begin with, if
234 we do, then we should track the bug where the problem originates
235 and not try to cover it up here.
237 Return a resolved expression of type UserImplicitCast on success
238 rather than true/false. Ravi: this is what I was talking about,
239 the pattern is to use a static method as a "constructor" for
242 Also, do not create arguments until the very last minute,
243 otherwise we always create the arguments even for lookups that
244 will never be performed.
246 (UserImplicitCast::Resolve): Eliminate, objects of type
247 UserImplicitCast are born in a fully resolved state.
249 * typemanager.cs (InitCoreTypes): Init also value_type
252 * expression.cs (Cast::Resolve): First resolve the child expression.
254 (LValue): Add new method AddressOf to be used by
257 Change the argument of Store to take an EmitContext instead of an
258 ILGenerator, because things like FieldExpr need to be able to call
259 their children expression to generate the instance code.
261 (Expression::Error, Expression::Warning): Sugar functions for
264 (Expression::MemberLookup): Accept a TypeContainer instead of a
265 Report as the first argument.
267 (Expression::ResolvePrimary): Killed. I still want to improve
268 this as currently the code is just not right.
270 (Expression::ResolveMemberAccess): Simplify, but it is still
273 (Unary::Resolve): Catch errors in AddressOf operators.
275 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
276 index to a byte for the short-version, or the compiler will choose
277 the wrong Emit call, which generates the wrong data.
279 (ParameterReference::Emit, ::Store): same.
281 (FieldExpr::AddressOf): Implement.
283 * typemanager.cs: TypeManager: made public variable instead of
286 * driver.cs: document --fatal.
288 * report.cs (ErrorMessage, WarningMessage): new names for the old
289 Error and Warning classes.
291 * cs-parser.jay (member_access): Turn built-in access to types
292 into a normal simplename
294 2001-09-27 Ravi Pratap <ravi@ximian.com>

308 I had introduced long ago (what's new ?).
310 * expression.cs (UserImplicitCast::CanConvert): Static method to do
311 the work of all the checking.
312 (ConvertImplicit): Call CanConvert and only then create object if necessary.
313 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
315 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
316 that is the right way.
318 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
319 overloading resolution. Use everywhere instead of cutting and pasting code.
321 (Binary::ResolveOperator): Use MakeUnionSet.
323 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
324 we have to convert to bool types. Not complete yet.
326 2001-09-27 Miguel de Icaza <miguel@ximian.com>
328 * typemanager.cs (TypeManager::CSharpName): support ushort.
330 * expression.cs (Expression::TryImplicitIntConversion): Attempts
331 to provide an expression that performsn an implicit constant int
332 conversion (section 6.1.6).
333 (Expression::ConvertImplicitRequired): Reworked to include
334 implicit constant expression conversions.
336 (Expression::ConvertNumericExplicit): Finished.
338 (Invocation::Emit): If InstanceExpression is null, then it means
339 that we perform a call on this.
341 2001-09-26 Miguel de Icaza <miguel@ximian.com>
343 * expression.cs (Unary::Emit): Remove some dead code.
344 (Probe): Implement Resolve and Emit for `is'.
345 (Expression::ConvertImplicitRequired): Attempt to do constant
346 expression conversions here. Maybe should be moved to
347 ConvertImplicit, but I am not sure.
348 (Expression::ImplicitLongConstantConversionPossible,
349 Expression::ImplicitIntConstantConversionPossible): New functions
350 that tell whether is it possible to apply an implicit constant
351 expression conversion.

360 (Parameters::VerifyArgs): Verifies that no two arguments have the
363 * class.cs (Operator): Update the operator names to reflect the
364 ones that the spec expects (as we are just stringizing the
367 * expression.cs (Unary::ResolveOperator): Fix bug: Use
368 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
369 previous usage did only work for our methods.
370 (Expression::ConvertImplicit): Handle decimal implicit numeric
372 (Expression::InternalTypeConstructor): Used to invoke constructors
373 on internal types for default promotions.
375 (Unary::Emit): Implement special handling for the pre/post
376 increment/decrement for overloaded operators, as they need to have
377 the same semantics as the other operators.
379 (Binary::ResolveOperator): ditto.
380 (Invocation::ConversionExists): ditto.
381 (UserImplicitCast::Resolve): ditto.
383 2001-09-26 Ravi Pratap <ravi@ximian.com>

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

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

442 * expression.cs (Unary::Emit): Emit code for -expr.
444 (Unary::ResolveOperator): Handle `Substract' for non-constants
445 (substract from zero from the non-constants).

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

508 multiple assignments.
509 (Expression::report118): Utility routine to report mismatches on
512 (Unary::Report23): Report impossible type/operator combination
515 (Unary::IsIncrementableNumber): Whether the type can be

521 (Invocation::Emit): Deal with new Emit convetion.
523 * All Expression derivatives: Updated their Emit method to return
524 whether they leave values on the stack or not.
526 * codegen.cs (CodeGen::EmitStatement): Pop values left on the
527 stack for expressions that are statements.
529 2001-09-20 Miguel de Icaza <miguel@ximian.com>
531 * expression.cs (LValue): New interface. Must be implemented by

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

580 expression for expressions which are just +expr.

605 (Binary::ResolveOperator): Re-write bits to quietly continue if no overloaded
606 operators are found instead of making noise ;-)

608 Binary::ResolveOperator does for Binary expressions.
609 (Unary.method, .Arguments): Add.
610 (Unary::OperName): Implement.
611 (Unary::ForceConversion): Copy and Paste !
613 * class.cs (Operator::Define): Fix a small bug for the case when we have
616 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
617 for the inbuilt operators. Only overloading works for now ;-)
619 2001-09-18 Miguel de Icaza <miguel@ximian.com>

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

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

663 initializers if none was specified.
664 Catch the fact that constructors should not have parameters.
666 * class.cs: Do not emit parent class initializers for static
667 constructors, that should be flagged as an error.
669 2001-09-18 Ravi Pratap <ravi@ximian.com>
671 * class.cs (RegisterMethodBuilder): Remove : it's unnecessary.
672 Move back code into TypeContainer::Populate.

696 2001-09-17 Miguel de Icaza <miguel@ximian.com>
698 * expression.cs (Expression::OverloadResolve): Drop TypeContainer
701 (Expression::MemberLookup): Provide a version that allows to
702 specify the MemberTypes and BindingFlags.

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

739 2001-09-17 Ravi Pratap <ravi@ximian.com>
741 * rootcontext.cs (IsNameSpace): Compare against null.
743 * everywhere : Correct spelling to 'Greater' and to 'Subtract'

808 container to evaluate permission settings.
810 * class.cs: Put Ravi's patch back in. He is right, and we will
811 have to cope with the
813 2001-09-14 Ravi Pratap <ravi@ximian.com>
815 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to

820 * driver.cs: Added --parse option that only parses its input files
823 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
824 incorrect. IsTopLevel is not used to tell whether an object is
825 root_types or not (that can be achieved by testing this ==
826 root_types). But to see if this is a top-level *class* (not
827 necessarly our "toplevel" container).
829 2001-09-14 Ravi Pratap <ravi@ximian.com>
831 * enum.cs (Enum::Define): Modify to call the Lookup method on the
832 parent instead of a direct call to GetType.
834 2001-09-14 Ravi Pratap <ravi@ximian.com>
836 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
837 Modifiers.TypeAttr. This should just be a call to that method.

853 * modifiers.cs (MethodAttr): Re-write.
854 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
856 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
857 of top-level types as claimed.
859 2001-09-13 Miguel de Icaza <miguel@ximian.com>
861 * expression.cs (MemberLookup): Fruitless attempt to lookup
862 constructors. Maybe I need to emit default constructors? That
863 might be it (currently .NET emits this for me automatically).
864 (Invocation::OverloadResolve): Cope with Arguments == null.
865 (Invocation::EmitArguments): new function, shared by the new

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

899 (Binary::ResolveOperator): Set the return type to boolean for
900 comparission operators
902 * typemanager.cs: Remove debugging print code.
904 (Invocation::Resolve): resolve type.
906 * class.cs: Allocate a MemberInfo of the correct size, as the code
907 elsewhere depends on the test to reflect the correct contents.
909 (Method::) Keep track of parameters, due to System.Reflection holes
911 (TypeContainer::Populate): Keep track of MethodBuilders to Method
914 (TypeContainer::FindMembers): Use ArrayList and then copy an array
915 of the exact size and return that.
917 (Class::LookupMethodByBuilder): New function that maps
918 MethodBuilders to its methods. Required to locate the information
919 on methods because System.Reflection bit us again.
921 * support.cs: New file, contains an interface ParameterData and
922 two implementations: ReflectionParameters and InternalParameters
923 used to access Parameter information. We will need to grow this
926 * expression.cs (Invocation::GetParameterData): implement a cache
927 and a wrapper around the ParameterData creation for methods.
928 (Invocation::OverloadResolve): Use new code.
930 2001-09-13 Ravi Pratap <ravi@ximian.com>

941 initialized with the full type once it is resolved.
943 2001-09-12 Miguel de Icaza <miguel@ximian.com>
945 * parameter.cs (GetParameterInfo): Use a type cache to compute
946 things only once, and to reuse this information

949 (OpcodeCast::Emit): fix.
951 (ParameterReference::Resolve): Implement.

1034 addOn_ and removeOn_
1036 * genericparser.cs (GenericParser::error): Overloaded method to handle the case
1037 of the location being passed in too. Ideally, this should go later since all
1038 error reporting should be done through the Report object.
1040 * class.cs (TypeContainer.Indexers): New property to access the list of indexers.
1041 (Populate): Iterate thru the indexers we have and define them too.

1362 readonly fields for all these cases ?
1364 2001-08-31 Ravi Pratap <ravi@che.iitm.ac.in>
1366 * class.cs (Property): Revamp to use the convention of making fields readonly.
1367 Accordingly modify code elsewhere.
1369 * class.cs : Apply patch from Mr. Mandar <go_mono@hotmail.com> for implementing
1370 the Define method of the Property class.
1372 * class.cs : Clean up applied patch and update references to variables etc. Fix
1374 (TypeContainer::Populate): Update to define all the properties we have. Also
1375 define all enumerations.
1377 * enum.cs (Define): Implement.
1379 2001-08-31 Ravi Pratap <ravi@che.iitm.ac.in>
1381 * cs-parser.jay (overloadable_operator): The semantic value is an
1382 enum of the Operator class.
1383 (operator_declarator): Implement actions.
1384 (operator_declaration): Implement.
1386 * class.cs (Operator::CheckUnaryOperator): New static method to help in checking
1387 validity of definitions.
1388 (Operator::CheckBinaryOperator): Static method to check for binary operators
1389 (TypeContainer::AddOperator): New method to add an operator to a type.
1391 * cs-parser.jay (indexer_declaration): Added line to actually call the
1392 AddIndexer method so it gets added ;-)
1394 * ../errors/errors.txt : Update to include new error numbers. Are these numbers
1395 already taken care of by the MS compiler ?
1397 2001-08-29 Ravi Pratap <ravi@che.iitm.ac.in>
1399 * class.cs (Operator): New class for operator declarations.
1400 (Operator::OpType): Enum for the various operators.
1402 2001-08-29 Ravi Pratap <ravi@che.iitm.ac.in>
1404 * class.cs (TypeContainer::AddIndexer): Remove FIXME comment. We

1407 * cs-parser.jay (general_catch_clause): Comment out
1408 (specific_catch_clauses, specific_catch_clause): Ditto.
1409 (opt_general_catch_clause, opt_specific_catch_clauses): Ditto

1411 (catch_clause): Rewrite to use the new productions above
1412 (catch_clauses): Modify accordingly.
1413 (opt_catch_clauses): New production to use in try_statement
1414 (try_statement): Revamp. Basically, we get rid of one unnecessary rule
1415 and re-write the code in the actions to extract the specific and
1416 general catch clauses by being a little smart ;-)
1418 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
1419 Hooray, try and catch statements parse fine !
1421 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
1423 * statement.cs (Block::GetVariableType): Fix logic to extract the type
1424 string from the hashtable of variables.
1426 * cs-parser.jay (event_accessor_declarations): Trivial fix. Man, how did
1427 I end up making that mistake ;-)
1428 (catch_clauses): Fixed gross error which made Key and Value of the
1429 DictionaryEntry the same : $1 !!
1431 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
1433 * cs-tokenizer.cs (initTokens): Add keywords 'add' and 'remove'
1435 * cs-parser.jay (event_declaration): Correct to remove the semicolon
1436 when the add and remove accessors are specified.
1438 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
1440 * cs-parser.jay (IndexerDeclaration): New helper class to hold
1441 information about indexer_declarator.
1442 (indexer_declarator): Implement actions.
1443 (parsing_indexer): New local boolean used to keep track of whether
1444 we are parsing indexers or properties. This is necessary because
1445 implicit_parameters come into picture even for the get accessor in the
1447 (get_accessor_declaration, set_accessor_declaration): Correspondingly modified.
1449 * class.cs (Indexer): New class for indexer declarations.
1450 (TypeContainer::AddIndexer): New method to add an indexer to a type.
1451 (TypeContainer::indexers): New member to hold list of indexers for the
1454 2001-08-27 Ravi Pratap <ravi@che.iitm.ac.in>
1456 * cs-parser.jay (add_accessor_declaration): Implement action.
1457 (remove_accessor_declaration): Implement action.
1458 (event_accessors_declaration): Implement

1461 * class.cs (Event): New class to hold information about event
1463 (TypeContainer::AddEvent): New method to add an event to a type
1464 (TypeContainer::events): New member to hold list of events.
1466 * cs-parser.jay (event_declaration): Implement actions.
1468 2001-08-27 Ravi Pratap <ravi@che.iitm.ac.in>
1470 * cs-parser.jay (dim_separators): Implement. Make it a string
1471 concatenating all the commas together, just as they appear.
1472 (opt_dim_separators): Modify accordingly
1473 (rank_specifiers): Update accordingly. Basically do the same
1474 thing - instead, collect the brackets here.
1475 (opt_rank_sepcifiers): Modify accordingly.
1476 (array_type): Modify to actually return the complete type string
1477 instead of ignoring the rank_specifiers.
1478 (expression_list): Implement to collect the expressions
1479 (variable_initializer): Implement. We make it a list of expressions
1480 essentially so that we can handle the array_initializer case neatly too.
1481 (variable_initializer_list): Implement.
1482 (array_initializer): Make it a list of variable_initializers
1483 (opt_array_initializer): Modify accordingly.
1485 * expression.cs (New::NType): Add enumeration to help us
1486 keep track of whether we have an object/delegate creation
1487 or an array creation.
1488 (New:NewType, New::Rank, New::Indices, New::Initializers): New
1489 members to hold data about array creation.
1490 (New:New): Modify to update NewType
1491 (New:New): New Overloaded contructor for the array creation
1494 * cs-parser.jay (array_creation_expression): Implement to call
1495 the overloaded New constructor.
1497 2001-08-26 Ravi Pratap <ravi@che.iitm.ac.in>
1499 * class.cs (TypeContainer::Constructors): Return member
1500 constructors instead of returning null.
1502 2001-08-26 Miguel de Icaza <miguel@ximian.com>
1504 * typemanager.cs (InitCoreTypes): Initialize the various core
1505 types after we have populated the type manager with the user
1506 defined types (this distinction will be important later while
1507 compiling corlib.dll)
1509 * expression.cs, literal.cs, assign.cs, constant.cs: Started work
1510 on Expression Classification. Now all expressions have a method
1511 `Resolve' and a method `Emit'.
1513 * codegen.cs, cs-parser.jay: Fixed the bug that stopped code
1514 generation from working. Also add some temporary debugging
1517 2001-08-24 Miguel de Icaza <miguel@ximian.com>
1519 * codegen.cs: Lots of code generation pieces. This is only the
1520 beginning, will continue tomorrow with more touches of polish. We
1521 handle the fundamentals of if, while, do, for, return. Others are
1522 trickier and I need to start working on invocations soon.
1524 * gen-treedump.cs: Bug fix, use s.Increment here instead of
1527 * codegen.cs (EmitContext): New struct, used during code
1528 emission to keep a context. Most of the code generation will be
1531 * cs-parser.jay: Add embedded blocks to the list of statements of
1532 this block. So code generation proceeds in a top down fashion.
1534 2001-08-23 Miguel de Icaza <miguel@ximian.com>
1536 * statement.cs: Add support for multiple child blocks.
1538 2001-08-22 Miguel de Icaza <miguel@ximian.com>
1540 * codegen.cs (EmitCode): New function, will emit the code for a
1541 Block of code given a TypeContainer and its ILGenerator.
1543 * statement.cs (Block): Standard public readonly optimization.
1544 (Block::Block constructors): Link children.
1545 (Block::Child): Child Linker.
1546 (Block::EmitVariables): Emits IL variable declarations.
1548 * class.cs: Drop support for MethodGroups here, delay until
1550 (Method::): Applied the same simplification that I did before, and
1551 move from Properties to public readonly fields.
1552 (Method::ParameterTypes): Returns the parameter types for the
1553 function, and implements a cache that will be useful later when I
1554 do error checking and the semantic analysis on the methods is
1556 (Constructor::GetCallingConvention): Renamed from CallingConvetion
1557 and made a method, optional argument tells whether this is a class
1558 or a structure to apply the `has-this' bit.
1559 (Method::GetCallingConvention): Implement, returns the calling
1561 (Method::Define): Defines the type, a second pass is performed
1562 later to populate the methods.
1564 (Constructor::ParameterTypes): implement a cache similar to the
1565 one on Method::ParameterTypes, useful later when we do semantic
1568 (TypeContainer::EmitMethod): New method. Emits methods.
1570 * expression.cs: Removed MethodGroup class from here.
1572 * parameter.cs (Parameters::GetCallingConvention): new method.

1576 * class.cs (TypeContainer::Populate): Drop RootContext from the
1579 (Constructor::CallingConvention): Returns the calling convention.
1580 (Constructor::ParameterTypes): Returns the constructor parameter
1583 (TypeContainer::AddConstructor): Keep track of default constructor
1584 and the default static constructor.
1586 (Constructor::) Another class that starts using `public readonly'
1587 instead of properties.
1589 (Constructor::IsDefault): Whether this is a default constructor.
1591 (Field::) use readonly public fields instead of properties also.
1593 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
1594 track of static constructors; If none is used, turn on
1595 BeforeFieldInit in the TypeAttributes.
1597 * cs-parser.jay (opt_argument_list): now the return can be null
1598 for the cases where there are no arguments.
1600 (constructor_declarator): If there is no implicit `base' or
1601 `this', then invoke the default parent constructor.
1603 * modifiers.cs (MethodAttr): New static function maps a set of
1604 modifiers flags into a MethodAttributes enum
1605 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
1606 MethodAttr, TypeAttr to represent the various mappings where the
1608 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
1610 2001-08-19 Miguel de Icaza <miguel@ximian.com>
1612 * parameter.cs (GetParameterInfo): Fix bug where there would be no
1615 * interface.cs (PopulateIndexer): Implemented the code generator
1616 for interface indexers.
1618 2001-08-17 Miguel de Icaza <miguel@ximian.com>
1620 * interface.cs (InterfaceMemberBase): Now we track the new status
1623 (PopulateProperty): Implement property population. Woohoo! Got
1624 Methods and Properties going today.
1626 Removed all the properties for interfaces, and replaced them with
1627 `public readonly' fields.
1629 2001-08-16 Miguel de Icaza <miguel@ximian.com>
1631 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
1632 initialize their hashtables/arraylists only when they are needed
1633 instead of doing this always.
1635 * parameter.cs: Handle refs and out parameters.
1637 * cs-parser.jay: Use an ArrayList to construct the arguments
1638 instead of the ParameterCollection, and then cast that to a
1641 * parameter.cs: Drop the use of ParameterCollection and use
1642 instead arrays of Parameters.
1644 (GetParameterInfo): Use the Type, not the Name when resolving
1647 2001-08-13 Miguel de Icaza <miguel@ximian.com>
1649 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
1650 and instead use public readonly fields.
1652 * class.cs: Put back walking code for type containers.
1654 2001-08-11 Miguel de Icaza <miguel@ximian.com>
1656 * class.cs (MakeConstant): Code to define constants.
1658 * rootcontext.cs (LookupType): New function. Used to locate types
1661 2001-08-08 Miguel de Icaza <miguel@ximian.com>
1663 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
1664 this System.Reflection code is. Kudos to Microsoft
1666 * typemanager.cs: Implement a type cache and avoid loading all
1667 types at boot time. Wrap in LookupType the internals. This made
1668 the compiler so much faster. Wow. I rule!
1670 * driver.cs: Make sure we always load mscorlib first (for
1671 debugging purposes, nothing really important).
1673 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
1674 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
1676 * rootcontext.cs: Lookup types on their namespace; Lookup types
1677 on namespaces that have been imported using the `using' keyword.
1679 * class.cs (TypeContainer::TypeAttr): Virtualize.
1680 (Class::TypeAttr): Return attributes suitable for this bad boy.
1681 (Struct::TypeAttr): ditto.
1682 Handle nested classes.
1683 (TypeContainer::) Remove all the type visiting code, it is now
1684 replaced with the rootcontext.cs code
1686 * rootcontext.cs (GetClassBases): Added support for structs.
1688 2001-08-06 Miguel de Icaza <miguel@ximian.com>
1690 * interface.cs, statement.cs, class.cs, parameter.cs,
1691 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
1692 Drop use of TypeRefs, and use strings instead.
1694 2001-08-04 Miguel de Icaza <miguel@ximian.com>
1698 * class.cs (Struct::Struct): set the SEALED flags after
1699 checking the modifiers.
1700 (TypeContainer::TypeAttr): new property, returns the
1701 TypeAttributes for a class.
1703 * cs-parser.jay (type_list): Oops, list production was creating a
1704 new list of base types.
1706 * rootcontext.cs (StdLib): New property.
1707 (GetInterfaceTypeByName): returns an interface by type name, and
1708 encapsulates error handling here.
1709 (GetInterfaces): simplified.
1710 (ResolveTree): Encapsulated all the tree resolution here.
1711 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
1714 * driver.cs: Add support for --nostdlib, to avoid loading the
1716 (Main): Do not put tree resolution here.
1718 * rootcontext.cs: Beginning of the class resolution.
1720 2001-08-03 Miguel de Icaza <miguel@ximian.com>
1722 * rootcontext.cs: Provide better error reporting.
1724 * cs-parser.jay (interface_base): set our $$ to be interfaces.
1726 * rootcontext.cs (CreateInterface): Handle the case where there
1727 are no parent interfaces.
1729 (CloseTypes): Routine to flush types at the end.
1730 (CreateInterface): Track types.
1731 (GetInterfaces): Returns an array of Types from the list of
1734 * typemanager.c (AddUserType): Mechanism to track user types (puts
1735 the type on the global type hash, and allows us to close it at the
1738 2001-08-02 Miguel de Icaza <miguel@ximian.com>
1740 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
1741 RecordInterface instead.
1743 * cs-parser.jay: Updated to reflect changes above.
1745 * decl.cs (Definition): Keep track of the TypeBuilder type that
1746 represents this type here. Not sure we will use it in the long
1747 run, but wont hurt for now.
1749 * driver.cs: Smaller changes to accomodate the new code.
1751 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
1754 * rootcontext.cs (CreateInterface): New method, used to create
1755 the System.TypeBuilder type for interfaces.
1756 (ResolveInterfaces): new entry point to resolve the interface
1758 (CodeGen): Property, used to keep track of the code generator.
1760 2001-07-26 Miguel de Icaza <miguel@ximian.com>
1762 * cs-parser.jay: Add a second production for delegate_declaration
1765 (enum_body): Put an opt_comma here instead of putting it on
1766 enum_body or enum_member_declarations so we can handle trailing
1767 commas on enumeration members. Gets rid of a shift/reduce.
1769 (type_list): Need a COMMA in the middle.
1771 (indexer_declaration): Tell tokenizer to recognize get/set
1773 * Remove old targets.
1775 * Re-add the parser target.
1777 2001-07-13 Simon Cozens <simon@simon-cozens.org>
1779 * cs-parser.jay: Add precendence rules for a number of operators
1780 ot reduce the number of shift/reduce conflicts in the grammar.
1782 2001-07-17 Miguel de Icaza <miguel@ximian.com>
1784 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
1787 Get rid of old crufty code.
1789 * rootcontext.cs: Use this to keep track of the parsed
1790 representation and the defined types available to the program.
1792 * gen-treedump.cs: adjust for new convention.
1794 * type.cs: Split out the type manager, and the assembly builder
1797 * typemanager.cs: the type manager will live here now.
1799 * cil-codegen.cs: And the code generator here.

1803 * makefile: Fixed up for easy making.
1805 2001-07-13 Simon Cozens <simon@simon-cozens.org>
1807 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
1810 (unary_expression): Expand pre_increment_expression and
1811 post_decrement_expression to reduce a shift/reduce.
1813 2001-07-11 Simon Cozens
1815 * cs-tokenizer.cs: Hex numbers should begin with a 0.
1817 Improve allow_keyword_as_indent name.
1819 2001-06-19 Miguel de Icaza <miguel@ximian.com>
1821 * Adjustments for Beta2.
1823 2001-06-13 Miguel de Icaza <miguel@ximian.com>
1825 * decl.cs: Added `Define' abstract method.
1826 (InTransit): new property, used to catch recursive definitions.
1828 * interface.cs: Implement `Define'.
1830 * modifiers.cs: Map Modifiers.constants to
1831 System.Reflection.TypeAttribute flags.
1833 * class.cs: Keep track of types and user-defined types.
1834 (BuilderInit): New method for creating an assembly
1835 (ResolveType): New function to launch the resolution process, only
1836 used by interfaces for now.
1838 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
1839 that are inserted into the name space.
1841 2001-06-08 Miguel de Icaza <miguel@ximian.com>
1843 * ARGH. I have screwed up my tree so many times due to the use of
1844 rsync rather than using CVS. Going to fix this at once.
1846 * driver.cs: Objetify driver. Load assemblies, use assemblies to
1849 2001-06-07 Miguel de Icaza <miguel@ximian.com>
1851 * Experiment successful: Use System.Type rather that our own
1854 2001-05-25 Miguel de Icaza <miguel@ximian.com>
1856 * cs-parser.jay: Removed nsAliases from here.
1858 Use new namespaces, handle `using XXX;'
1860 * namespace.cs: Reimplemented namespace handling, use a recursive
1861 definition of the class. Now we can keep track of using clauses
1862 and catch invalid using clauses.
1864 2001-05-24 Miguel de Icaza <miguel@ximian.com>
1866 * gen-treedump.cs: Adapted for all the renaming.
1868 * expression.cs (Expression): this class now has a Type property
1869 which returns an expression Type.
1871 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
1872 `Type', as this has a different meaning now in the base
1874 2001-05-22 Miguel de Icaza <miguel@ximian.com>
1876 * interface.cs, class.cs: Removed from all the sources the
1877 references to signature computation, as we can not do method
1878 signature computation during the parsing time, as we are not
1879 trying to solve at that point distinguishing:
1883 void a (NS.Blah x) {}
1886 Which depending on the context might be valid or not, as we do not
1887 know if Blah is the same thing as NS.Blah at that point.
1889 * Redid everything so the code uses TypeRefs now instead of
1890 Types. TypeRefs are just temporary type placeholders, that need
1891 to be resolved. They initially have a pointer to a string and the
1892 current scope in which they are used. This is used later by the
1893 compiler to resolve the reference to an actual Type.
1895 * DeclSpace is no longer a CIR.Type, and neither are
1896 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
1897 are all DeclSpaces, but no Types.
1899 * type.cs (TypeRefManager): This implements the TypeRef manager,
1900 which keeps track of all the types that need to be resolved after
1901 the parsing has finished.
1903 2001-05-13 Miguel de Icaza <miguel@ximian.com>
1905 * ARGH. We are going to have to store `foreach' as a class rather
1906 than resolving it, as we need to verify error 1579 after name
1907 resolution. *OR* we could keep a flag that says `This request to
1908 IEnumerator comes from a foreach statement' which we can then use
1909 to generate the error.
1911 2001-05-10 Miguel de Icaza <miguel@ximian.com>
1913 * class.cs (TypeContainer.AddMethod): we now add methods to the
1914 MethodGroup instead of the method hashtable.
1916 * expression.cs: Add MethodGroup abstraction, which gets us one
1917 step closer to the specification in the way we handle method
1920 * cs-parser.jay (primary_expression): qualified_identifier now
1921 tried to match up an identifier to a local variable reference or
1922 to a parameter reference.
1924 current_local_parameters is now a parser global variable that
1925 points to the current parameters for the block, used during name
1928 (property_declaration): Now creates an implicit `value' argument to
1931 2001-05-09 Miguel de Icaza <miguel@ximian.com>
1933 * parameter.cs: Do not use `param' arguments as part of the
1934 signature, per the spec.
1936 2001-05-08 Miguel de Icaza <miguel@ximian.com>
1938 * decl.cs: Base class for classes, structs and interfaces. This
1939 is the "Declaration Space"
1941 * cs-parser.jay: Use CheckDef for checking declaration errors
1942 instead of having one on each function.
1944 * class.cs: Factor out some code for handling error handling in
1945 accordance to the "Declarations" section in the "Basic Concepts"
1946 chapter in the ECMA C# spec.
1948 * interface.cs: Make all interface member classes derive from
1949 InterfaceMemberBase.
1951 2001-05-07 Miguel de Icaza <miguel@ximian.com>
1953 * Many things: all interfaces are parsed and generated in
1954 gen-treedump. Support for member variables, constructors,
1955 destructors, properties, constants is there.
1957 Beginning of the IL backend, but very little done, just there for
1960 2001-04-29 Miguel de Icaza <miguel@ximian.com>
1962 * cs-parser.jay: Fix labeled statement.
1964 * cs-tokenizer.cs (escape): Escape " and ' always.
1965 ref_line, ref_name: keep track of the line/filename as instructed
1966 by #line by the compiler.
1969 2001-04-27 Miguel de Icaza <miguel@ximian.com>
1971 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
1972 to match the values in System.CodeDOM.
1974 Divid renamed to Divide.
1976 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
1978 (Statements.set): remove.
1980 * System.CodeDOM/CodeCatchClause.cs: always have a valid
1983 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
1984 falseStatements always have valid values.
1986 * cs-parser.jay: Use System.CodeDOM now.
