1 2001-10-01 Miguel de Icaza <miguel@ximian.com>
3 * cs-tokenizer.cs: Reimplemented Location to be a struct with a
4 single integer which is really efficient
6 2001-10-01 Ravi Pratap <ravi@ximian.com>
8 * expression.cs (Expression::ImplicitUserConversion): Use location
9 even in the case when we are examining True operators.
11 * class.cs (Operator::Define): Perform extensive checks to conform
12 with the rules for operator overloading in the spec.
14 * expression.cs (Expression::ImplicitReferenceConversion): Implement
15 some of the other conversions mentioned in the spec.
17 * typemanager.cs (array_type): New static member for the System.Array built-in
20 (cloneable_interface): For System.ICloneable interface.
22 * driver.cs (Driver::Driver): Initialize TypeManager's core types even before
23 we start resolving the tree and populating types.
25 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
27 2001-10-01 Miguel de Icaza <miguel@ximian.com>
29 * expression.cs (Expression::ExprClassFromMemberInfo,
30 Expression::Literalize): Create literal expressions from
31 FieldInfos which are literals.
33 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
34 type casts, because they were wrong. The test suite in tests
37 (ImplicitNumericConversion): ushort to ulong requires a widening
40 Int32 constant to long requires widening cast as well.
42 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
43 for integers because the type on the stack is not i4.
45 2001-09-30 Miguel de Icaza <miguel@ximian.com>
47 * expression.cs (report118): require location argument.
49 * parameter.cs: Do not dereference potential null value.
51 * class.cs: Catch methods that lack the `new' keyword when
52 overriding a name. Report warnings when `new' is used without
53 anything being there to override.
55 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
57 * class.cs: Only add constructor to hashtable if it is non-null
58 (as now constructors can fail on define).
60 (TypeManager, Class, Struct): Take location arguments.
62 Catch field instance initialization in structs as errors.
64 accepting_filter: a new filter for FindMembers that is static so
65 that we dont create an instance per invocation.
67 (Constructor::Define): Catch errors where a struct constructor is
70 * cs-parser.jay: Pass location information for various new
73 * delegate.cs (Delegate): take a location argument.
75 * driver.cs: Do not call EmitCode if there were problesm in the
76 Definition of the types, as many Builders wont be there.
78 * decl.cs (Decl::Decl): Require a location argument.
80 * cs-tokenizer.cs: Handle properly hex constants that can not fit
81 into integers, and find the most appropiate integer for it.
83 * literal.cs: Implement ULongLiteral.
85 * rootcontext.cs: Provide better information about the location of
86 failure when CreateType fails.
88 2001-09-29 Miguel de Icaza <miguel@ximian.com>
90 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
93 * expression.cs (Binary::CheckShiftArguments): Add missing type
95 (Binary::ResolveOperator): Add type to the logical and and logical
96 or, Bitwise And/Or and Exclusive Or code paths, it was missing
99 (Binary::DoNumericPromotions): In the case where either argument
100 is ulong (and most signed types combined with ulong cause an
101 error) perform implicit integer constant conversions as well.
103 2001-09-28 Miguel de Icaza <miguel@ximian.com>
105 * expression.cs (UserImplicitCast): Method should always be
107 (Invocation::BetterConversion): Simplified test for IntLiteral.
109 (Expression::ImplicitNumericConversion): Split this routine out.
110 Put the code that performs implicit constant integer conversions
113 (Expression::Resolve): Become a wrapper around DoResolve so we can
114 check eclass and type being set after resolve.
116 (Invocation::Badness): Remove this dead function
118 (Binary::ResolveOperator): Do not compute the expensive argumnets
119 unless we have a union for it.
121 (Probe::Emit): Is needs to do an isinst and then
122 compare against null.
124 (::CanConvert): Added Location argument. If the Location argument
125 is null (Location.Null), then we do not report errors. This is
126 used by the `probe' mechanism of the Explicit conversion. We do
127 not want to generate an error for something that the user
128 explicitly requested to be casted. But the pipeline for an
129 explicit cast first tests for potential implicit casts.
131 So for now, if the Location is null, it means `Probe only' to
132 avoid adding another argument. Might have to revise this
135 (ClassCast): New class used to type cast objects into arbitrary
136 classes (used in Explicit Reference Conversions).
138 Implement `as' as well.
140 Reverted all the patches from Ravi below: they were broken:
142 * The use of `level' as a mechanism to stop recursive
143 invocations is wrong. That was there just to catch the
144 bug with a strack trace but not as a way of addressing
147 To fix the problem we have to *understand* what is going
148 on and the interactions and come up with a plan, not
149 just get things going.
151 * The use of the type conversion cache that I proposed
152 last night had an open topic: How does this work across
153 protection domains. A user defined conversion might not
154 be public in the location where we are applying the
155 conversion, a different conversion might be selected
156 (ie, private A->B (better) but public B->A (worse),
157 inside A, A->B applies, but outside it, B->A will
160 * On top of that (ie, even if the above is solved),
161 conversions in a cache need to be abstract. Ie, `To
162 convert from an Int to a Short use an OpcodeCast', not
163 `To convert from an Int to a Short use the OpcodeCast on
164 the variable 5' (which is what this patch was doing).
166 2001-09-28 Ravi Pratap <ravi@ximian.com>
168 * expression.cs (Invocation::ConversionExists): Re-write to use
171 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
172 cache all conversions done, not just user-defined ones.
174 (Invocation::BetterConversion): The real culprit. Use ConversionExists
175 to determine if a conversion exists instead of acutually trying to
176 perform the conversion. It's faster too.
178 (Expression::ConvertExplicit): Modify to use ConversionExists to check
179 and only then attempt the implicit conversion.
181 2001-09-28 Ravi Pratap <ravi@ximian.com>
183 * expression.cs (ConvertImplicit): Use a cache for conversions
184 already found. Check level of recursion and bail out if necessary.
186 2001-09-28 Miguel de Icaza <miguel@ximian.com>
188 * typemanager.cs (string_concat_string_string, string_concat_object_object):
189 Export standard methods that we expect for string operations.
191 * statement.cs (Block::UsageWarning): Track usage of variables and
192 report the errors for not used variables.
194 * expression.cs (Conditional::Resolve, ::Emit): Implement ?:
197 2001-09-27 Miguel de Icaza <miguel@ximian.com>
199 * codegen.cs: remove unnneded code
201 * expression.cs: Removed BuiltinTypeAccess class
203 Fix the order in which implicit conversions are
206 The previous fixed dropped support for boxed conversions (adding a
207 test to the test suite now)
209 (UserImplicitCast::CanConvert): Remove test for source being null,
210 that code is broken. We should not feed a null to begin with, if
211 we do, then we should track the bug where the problem originates
212 and not try to cover it up here.
214 Return a resolved expression of type UserImplicitCast on success
215 rather than true/false. Ravi: this is what I was talking about,
216 the pattern is to use a static method as a "constructor" for
219 Also, do not create arguments until the very last minute,
220 otherwise we always create the arguments even for lookups that
221 will never be performed.
223 (UserImplicitCast::Resolve): Eliminate, objects of type
224 UserImplicitCast are born in a fully resolved state.
226 * typemanager.cs (InitCoreTypes): Init also value_type
229 * expression.cs (Cast::Resolve): First resolve the child expression.
231 (LValue): Add new method AddressOf to be used by
234 Change the argument of Store to take an EmitContext instead of an
235 ILGenerator, because things like FieldExpr need to be able to call
236 their children expression to generate the instance code.
238 (Expression::Error, Expression::Warning): Sugar functions for
241 (Expression::MemberLookup): Accept a TypeContainer instead of a
242 Report as the first argument.
244 (Expression::ResolvePrimary): Killed. I still want to improve
245 this as currently the code is just not right.
247 (Expression::ResolveMemberAccess): Simplify, but it is still
250 (Unary::Resolve): Catch errors in AddressOf operators.
252 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
253 index to a byte for the short-version, or the compiler will choose
254 the wrong Emit call, which generates the wrong data.
256 (ParameterReference::Emit, ::Store): same.
258 (FieldExpr::AddressOf): Implement.
260 * typemanager.cs: TypeManager: made public variable instead of
263 * driver.cs: document --fatal.
265 * report.cs (ErrorMessage, WarningMessage): new names for the old
266 Error and Warning classes.
268 * cs-parser.jay (member_access): Turn built-in access to types
269 into a normal simplename
271 2001-09-27 Ravi Pratap <ravi@ximian.com>
273 * expression.cs (Invocation::BetterConversion): Fix to cope
274 with q being null, since this was introducing a bug.

284 * class.cs (TypeContainer::AddConstructor): Fix a stupid bug
285 I had introduced long ago (what's new ?).
287 * expression.cs (UserImplicitCast::CanConvert): Static method to do
288 the work of all the checking.
289 (ConvertImplicit): Call CanConvert and only then create object if necessary.
290 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
292 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
293 that is the right way.
295 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
296 overloading resolution. Use everywhere instead of cutting and pasting code.
298 (Binary::ResolveOperator): Use MakeUnionSet.
300 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
301 we have to convert to bool types. Not complete yet.
303 2001-09-27 Miguel de Icaza <miguel@ximian.com>
305 * typemanager.cs (TypeManager::CSharpName): support ushort.
307 * expression.cs (Expression::TryImplicitIntConversion): Attempts
308 to provide an expression that performsn an implicit constant int
309 conversion (section 6.1.6).
310 (Expression::ConvertImplicitRequired): Reworked to include
311 implicit constant expression conversions.
313 (Expression::ConvertNumericExplicit): Finished.
315 (Invocation::Emit): If InstanceExpression is null, then it means
316 that we perform a call on this.
318 2001-09-26 Miguel de Icaza <miguel@ximian.com>
320 * expression.cs (Unary::Emit): Remove some dead code.
321 (Probe): Implement Resolve and Emit for `is'.
322 (Expression::ConvertImplicitRequired): Attempt to do constant
323 expression conversions here. Maybe should be moved to
324 ConvertImplicit, but I am not sure.
325 (Expression::ImplicitLongConstantConversionPossible,
326 Expression::ImplicitIntConstantConversionPossible): New functions
327 that tell whether is it possible to apply an implicit constant
328 expression conversion.

340 * class.cs (Operator): Update the operator names to reflect the
341 ones that the spec expects (as we are just stringizing the
344 * expression.cs (Unary::ResolveOperator): Fix bug: Use
345 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
346 previous usage did only work for our methods.
347 (Expression::ConvertImplicit): Handle decimal implicit numeric
349 (Expression::InternalTypeConstructor): Used to invoke constructors
350 on internal types for default promotions.
352 (Unary::Emit): Implement special handling for the pre/post
353 increment/decrement for overloaded operators, as they need to have
354 the same semantics as the other operators.
356 (Binary::ResolveOperator): ditto.
357 (Invocation::ConversionExists): ditto.
358 (UserImplicitCast::Resolve): ditto.
360 2001-09-26 Ravi Pratap <ravi@ximian.com>

376 * expression.cs (ExpressionStatement): New base class used for
377 expressions that can appear in statements, so that we can provide
378 an alternate path to generate expression that do not leave a value
381 (Expression::Emit, and all the derivatives): We no longer return
382 whether a value is left on the stack or not. Every expression
383 after being emitted leaves a single value on the stack.
385 * codegen.cs (EmitContext::EmitStatementExpression): Use the
386 facilties of ExpressionStatement if possible.
388 * cs-parser.jay: Update statement_expression.

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

479 * typemanager.cs: declare and load enum_type, delegate_type and
482 * expression.cs (Expression::Emit): Now emit returns a value that
483 tells whether a value is left on the stack or not. This strategy
484 might be reveted tomorrow with a mechanism that would address
485 multiple assignments.
486 (Expression::report118): Utility routine to report mismatches on
489 (Unary::Report23): Report impossible type/operator combination
492 (Unary::IsIncrementableNumber): Whether the type can be

498 (Invocation::Emit): Deal with new Emit convetion.
500 * All Expression derivatives: Updated their Emit method to return
501 whether they leave values on the stack or not.
503 * codegen.cs (CodeGen::EmitStatement): Pop values left on the
504 stack for expressions that are statements.
506 2001-09-20 Miguel de Icaza <miguel@ximian.com>
508 * expression.cs (LValue): New interface. Must be implemented by

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

585 Binary::ResolveOperator does for Binary expressions.
586 (Unary.method, .Arguments): Add.
587 (Unary::OperName): Implement.
588 (Unary::ForceConversion): Copy and Paste !
590 * class.cs (Operator::Define): Fix a small bug for the case when we have
593 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
594 for the inbuilt operators. Only overloading works for now ;-)
596 2001-09-18 Miguel de Icaza <miguel@ximian.com>

612 (FieldExpr::Emit): Implement.
614 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
615 the last instruction contains a return opcode to avoid generating

617 nice to pass the peverify output).
619 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
620 initializer for static and instance variables.
621 (Constructor::Emit): Allow initializer to be null in the case of
622 static constructors. Only emit initializer for instance

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

640 initializers if none was specified.
641 Catch the fact that constructors should not have parameters.
643 * class.cs: Do not emit parent class initializers for static
644 constructors, that should be flagged as an error.
646 2001-09-18 Ravi Pratap <ravi@ximian.com>
648 * class.cs (RegisterMethodBuilder): Remove : it's unnecessary.
649 Move back code into TypeContainer::Populate.

673 2001-09-17 Miguel de Icaza <miguel@ximian.com>
675 * expression.cs (Expression::OverloadResolve): Drop TypeContainer
678 (Expression::MemberLookup): Provide a version that allows to
679 specify the MemberTypes and BindingFlags.

687 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200
690 * class.cs (Constructor::Emit): Only emit if block is not null.
691 (TypeContainer::EmitDefaultConstructor): Removed routine, now we
692 deal with this by semantically definining it as if the user had
695 (TypeContainer::FindMembers): Removed ad-hoc hack to deal with
696 constructors as we now "emit" them at a higher level.
698 (TypeContainer::DefineDefaultConstructor): Used to define the
699 default constructors if none was provided.
701 (ConstructorInitializer): Add methods Resolve and Emit.
703 * expression.cs: Cast to ConstructorInfo instead of MethodInfo

785 container to evaluate permission settings.
787 * class.cs: Put Ravi's patch back in. He is right, and we will
788 have to cope with the
790 2001-09-14 Ravi Pratap <ravi@ximian.com>
792 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to

797 * driver.cs: Added --parse option that only parses its input files
800 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
801 incorrect. IsTopLevel is not used to tell whether an object is

803 root_types). But to see if this is a top-level *class* (not
804 necessarly our "toplevel" container).
806 2001-09-14 Ravi Pratap <ravi@ximian.com>
808 * enum.cs (Enum::Define): Modify to call the Lookup method on the

811 2001-09-14 Ravi Pratap <ravi@ximian.com>
813 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
814 Modifiers.TypeAttr. This should just be a call to that method.

830 * modifiers.cs (MethodAttr): Re-write.
831 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
833 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
834 of top-level types as claimed.
836 2001-09-13 Miguel de Icaza <miguel@ximian.com>
838 * expression.cs (MemberLookup): Fruitless attempt to lookup
839 constructors. Maybe I need to emit default constructors? That

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

877 comparission operators
879 * typemanager.cs: Remove debugging print code.
881 (Invocation::Resolve): resolve type.
883 * class.cs: Allocate a MemberInfo of the correct size, as the code
884 elsewhere depends on the test to reflect the correct contents.
886 (Method::) Keep track of parameters, due to System.Reflection holes
888 (TypeContainer::Populate): Keep track of MethodBuilders to Method
891 (TypeContainer::FindMembers): Use ArrayList and then copy an array
892 of the exact size and return that.
894 (Class::LookupMethodByBuilder): New function that maps
895 MethodBuilders to its methods. Required to locate the information
896 on methods because System.Reflection bit us again.
898 * support.cs: New file, contains an interface ParameterData and
899 two implementations: ReflectionParameters and InternalParameters
900 used to access Parameter information. We will need to grow this
903 * expression.cs (Invocation::GetParameterData): implement a cache

1011 addOn_ and removeOn_
1013 * genericparser.cs (GenericParser::error): Overloaded method to handle the case
1014 of the location being passed in too. Ideally, this should go later since all
1015 error reporting should be done through the Report object.
1017 * class.cs (TypeContainer.Indexers): New property to access the list of indexers.

1360 (operator_declarator): Implement actions.
1361 (operator_declaration): Implement.
1363 * class.cs (Operator::CheckUnaryOperator): New static method to help in checking
1364 validity of definitions.
1365 (Operator::CheckBinaryOperator): Static method to check for binary operators
1366 (TypeContainer::AddOperator): New method to add an operator to a type.
1368 * cs-parser.jay (indexer_declaration): Added line to actually call the
1369 AddIndexer method so it gets added ;-)
1371 * ../errors/errors.txt : Update to include new error numbers. Are these numbers
1372 already taken care of by the MS compiler ?
1374 2001-08-29 Ravi Pratap <ravi@che.iitm.ac.in>
1376 * class.cs (Operator): New class for operator declarations.
1377 (Operator::OpType): Enum for the various operators.
1379 2001-08-29 Ravi Pratap <ravi@che.iitm.ac.in>

1384 * cs-parser.jay (general_catch_clause): Comment out
1385 (specific_catch_clauses, specific_catch_clause): Ditto.
1386 (opt_general_catch_clause, opt_specific_catch_clauses): Ditto

1388 (catch_clause): Rewrite to use the new productions above
1389 (catch_clauses): Modify accordingly.
1390 (opt_catch_clauses): New production to use in try_statement
1391 (try_statement): Revamp. Basically, we get rid of one unnecessary rule
1392 and re-write the code in the actions to extract the specific and
1393 general catch clauses by being a little smart ;-)
1395 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
1396 Hooray, try and catch statements parse fine !
1398 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
1400 * statement.cs (Block::GetVariableType): Fix logic to extract the type
1401 string from the hashtable of variables.
1403 * cs-parser.jay (event_accessor_declarations): Trivial fix. Man, how did
1404 I end up making that mistake ;-)
1405 (catch_clauses): Fixed gross error which made Key and Value of the
1406 DictionaryEntry the same : $1 !!
1408 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
1410 * cs-tokenizer.cs (initTokens): Add keywords 'add' and 'remove'
1412 * cs-parser.jay (event_declaration): Correct to remove the semicolon
1413 when the add and remove accessors are specified.
1415 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
1417 * cs-parser.jay (IndexerDeclaration): New helper class to hold
1418 information about indexer_declarator.
1419 (indexer_declarator): Implement actions.
1420 (parsing_indexer): New local boolean used to keep track of whether
1421 we are parsing indexers or properties. This is necessary because
1422 implicit_parameters come into picture even for the get accessor in the
1424 (get_accessor_declaration, set_accessor_declaration): Correspondingly modified.
1426 * class.cs (Indexer): New class for indexer declarations.
1427 (TypeContainer::AddIndexer): New method to add an indexer to a type.
1428 (TypeContainer::indexers): New member to hold list of indexers for the
1431 2001-08-27 Ravi Pratap <ravi@che.iitm.ac.in>
1433 * cs-parser.jay (add_accessor_declaration): Implement action.
1434 (remove_accessor_declaration): Implement action.
1435 (event_accessors_declaration): Implement

1440 (TypeContainer::AddEvent): New method to add an event to a type
1441 (TypeContainer::events): New member to hold list of events.
1443 * cs-parser.jay (event_declaration): Implement actions.
1445 2001-08-27 Ravi Pratap <ravi@che.iitm.ac.in>
1447 * cs-parser.jay (dim_separators): Implement. Make it a string
1448 concatenating all the commas together, just as they appear.
1449 (opt_dim_separators): Modify accordingly
1450 (rank_specifiers): Update accordingly. Basically do the same
1451 thing - instead, collect the brackets here.
1452 (opt_rank_sepcifiers): Modify accordingly.
1453 (array_type): Modify to actually return the complete type string
1454 instead of ignoring the rank_specifiers.
1455 (expression_list): Implement to collect the expressions
1456 (variable_initializer): Implement. We make it a list of expressions
1457 essentially so that we can handle the array_initializer case neatly too.
1458 (variable_initializer_list): Implement.
1459 (array_initializer): Make it a list of variable_initializers
1460 (opt_array_initializer): Modify accordingly.
1462 * expression.cs (New::NType): Add enumeration to help us
1463 keep track of whether we have an object/delegate creation
1464 or an array creation.
1465 (New:NewType, New::Rank, New::Indices, New::Initializers): New
1466 members to hold data about array creation.
1467 (New:New): Modify to update NewType
1468 (New:New): New Overloaded contructor for the array creation
1471 * cs-parser.jay (array_creation_expression): Implement to call
1472 the overloaded New constructor.
1474 2001-08-26 Ravi Pratap <ravi@che.iitm.ac.in>
1476 * class.cs (TypeContainer::Constructors): Return member
1477 constructors instead of returning null.
1479 2001-08-26 Miguel de Icaza <miguel@ximian.com>
1481 * typemanager.cs (InitCoreTypes): Initialize the various core
1482 types after we have populated the type manager with the user
1483 defined types (this distinction will be important later while
1484 compiling corlib.dll)
1486 * expression.cs, literal.cs, assign.cs, constant.cs: Started work
1487 on Expression Classification. Now all expressions have a method
1488 `Resolve' and a method `Emit'.
1490 * codegen.cs, cs-parser.jay: Fixed the bug that stopped code
1491 generation from working. Also add some temporary debugging
1494 2001-08-24 Miguel de Icaza <miguel@ximian.com>
1496 * codegen.cs: Lots of code generation pieces. This is only the
1497 beginning, will continue tomorrow with more touches of polish. We
1498 handle the fundamentals of if, while, do, for, return. Others are
1499 trickier and I need to start working on invocations soon.
1501 * gen-treedump.cs: Bug fix, use s.Increment here instead of
1504 * codegen.cs (EmitContext): New struct, used during code
1505 emission to keep a context. Most of the code generation will be
1508 * cs-parser.jay: Add embedded blocks to the list of statements of
1509 this block. So code generation proceeds in a top down fashion.
1511 2001-08-23 Miguel de Icaza <miguel@ximian.com>
1513 * statement.cs: Add support for multiple child blocks.
1515 2001-08-22 Miguel de Icaza <miguel@ximian.com>
1517 * codegen.cs (EmitCode): New function, will emit the code for a
1518 Block of code given a TypeContainer and its ILGenerator.
1520 * statement.cs (Block): Standard public readonly optimization.
1521 (Block::Block constructors): Link children.
1522 (Block::Child): Child Linker.
1523 (Block::EmitVariables): Emits IL variable declarations.
1525 * class.cs: Drop support for MethodGroups here, delay until
1527 (Method::): Applied the same simplification that I did before, and
1528 move from Properties to public readonly fields.
1529 (Method::ParameterTypes): Returns the parameter types for the
1530 function, and implements a cache that will be useful later when I
1531 do error checking and the semantic analysis on the methods is
1533 (Constructor::GetCallingConvention): Renamed from CallingConvetion
1534 and made a method, optional argument tells whether this is a class
1535 or a structure to apply the `has-this' bit.
1536 (Method::GetCallingConvention): Implement, returns the calling
1538 (Method::Define): Defines the type, a second pass is performed
1539 later to populate the methods.
1541 (Constructor::ParameterTypes): implement a cache similar to the
1542 one on Method::ParameterTypes, useful later when we do semantic
1545 (TypeContainer::EmitMethod): New method. Emits methods.
1547 * expression.cs: Removed MethodGroup class from here.
1549 * parameter.cs (Parameters::GetCallingConvention): new method.

1556 (Constructor::CallingConvention): Returns the calling convention.
1557 (Constructor::ParameterTypes): Returns the constructor parameter
1560 (TypeContainer::AddConstructor): Keep track of default constructor
1561 and the default static constructor.
1563 (Constructor::) Another class that starts using `public readonly'
1564 instead of properties.
1566 (Constructor::IsDefault): Whether this is a default constructor.
1568 (Field::) use readonly public fields instead of properties also.
1570 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
1571 track of static constructors; If none is used, turn on
1572 BeforeFieldInit in the TypeAttributes.
1574 * cs-parser.jay (opt_argument_list): now the return can be null
1575 for the cases where there are no arguments.
1577 (constructor_declarator): If there is no implicit `base' or
1578 `this', then invoke the default parent constructor.
1580 * modifiers.cs (MethodAttr): New static function maps a set of
1581 modifiers flags into a MethodAttributes enum
1582 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
1583 MethodAttr, TypeAttr to represent the various mappings where the
1585 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
1587 2001-08-19 Miguel de Icaza <miguel@ximian.com>
1589 * parameter.cs (GetParameterInfo): Fix bug where there would be no
1592 * interface.cs (PopulateIndexer): Implemented the code generator
1593 for interface indexers.
1595 2001-08-17 Miguel de Icaza <miguel@ximian.com>
1597 * interface.cs (InterfaceMemberBase): Now we track the new status
1600 (PopulateProperty): Implement property population. Woohoo! Got
1601 Methods and Properties going today.
1603 Removed all the properties for interfaces, and replaced them with
1604 `public readonly' fields.
1606 2001-08-16 Miguel de Icaza <miguel@ximian.com>
1608 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
1609 initialize their hashtables/arraylists only when they are needed
1610 instead of doing this always.
1612 * parameter.cs: Handle refs and out parameters.
1614 * cs-parser.jay: Use an ArrayList to construct the arguments
1615 instead of the ParameterCollection, and then cast that to a
1618 * parameter.cs: Drop the use of ParameterCollection and use
1619 instead arrays of Parameters.
1621 (GetParameterInfo): Use the Type, not the Name when resolving
1624 2001-08-13 Miguel de Icaza <miguel@ximian.com>
1626 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
1627 and instead use public readonly fields.
1629 * class.cs: Put back walking code for type containers.
1631 2001-08-11 Miguel de Icaza <miguel@ximian.com>
1633 * class.cs (MakeConstant): Code to define constants.
1635 * rootcontext.cs (LookupType): New function. Used to locate types
1638 2001-08-08 Miguel de Icaza <miguel@ximian.com>
1640 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
1641 this System.Reflection code is. Kudos to Microsoft
1643 * typemanager.cs: Implement a type cache and avoid loading all
1644 types at boot time. Wrap in LookupType the internals. This made
1645 the compiler so much faster. Wow. I rule!
1647 * driver.cs: Make sure we always load mscorlib first (for
1648 debugging purposes, nothing really important).
1650 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
1651 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
1653 * rootcontext.cs: Lookup types on their namespace; Lookup types
1654 on namespaces that have been imported using the `using' keyword.
1656 * class.cs (TypeContainer::TypeAttr): Virtualize.
1657 (Class::TypeAttr): Return attributes suitable for this bad boy.
1658 (Struct::TypeAttr): ditto.
1659 Handle nested classes.
1660 (TypeContainer::) Remove all the type visiting code, it is now
1661 replaced with the rootcontext.cs code
1663 * rootcontext.cs (GetClassBases): Added support for structs.
1665 2001-08-06 Miguel de Icaza <miguel@ximian.com>
1667 * interface.cs, statement.cs, class.cs, parameter.cs,
1668 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
1669 Drop use of TypeRefs, and use strings instead.
1671 2001-08-04 Miguel de Icaza <miguel@ximian.com>
1675 * class.cs (Struct::Struct): set the SEALED flags after
1676 checking the modifiers.
1677 (TypeContainer::TypeAttr): new property, returns the
1678 TypeAttributes for a class.
1680 * cs-parser.jay (type_list): Oops, list production was creating a
1681 new list of base types.
1683 * rootcontext.cs (StdLib): New property.
1684 (GetInterfaceTypeByName): returns an interface by type name, and
1685 encapsulates error handling here.
1686 (GetInterfaces): simplified.
1687 (ResolveTree): Encapsulated all the tree resolution here.
1688 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
1691 * driver.cs: Add support for --nostdlib, to avoid loading the
1693 (Main): Do not put tree resolution here.
1695 * rootcontext.cs: Beginning of the class resolution.
1697 2001-08-03 Miguel de Icaza <miguel@ximian.com>
1699 * rootcontext.cs: Provide better error reporting.
1701 * cs-parser.jay (interface_base): set our $$ to be interfaces.
1703 * rootcontext.cs (CreateInterface): Handle the case where there
1704 are no parent interfaces.
1706 (CloseTypes): Routine to flush types at the end.
1707 (CreateInterface): Track types.
1708 (GetInterfaces): Returns an array of Types from the list of
1711 * typemanager.c (AddUserType): Mechanism to track user types (puts
1712 the type on the global type hash, and allows us to close it at the
1715 2001-08-02 Miguel de Icaza <miguel@ximian.com>
1717 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
1718 RecordInterface instead.
1720 * cs-parser.jay: Updated to reflect changes above.
1722 * decl.cs (Definition): Keep track of the TypeBuilder type that
1723 represents this type here. Not sure we will use it in the long
1724 run, but wont hurt for now.
1726 * driver.cs: Smaller changes to accomodate the new code.
1728 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
1731 * rootcontext.cs (CreateInterface): New method, used to create
1732 the System.TypeBuilder type for interfaces.
1733 (ResolveInterfaces): new entry point to resolve the interface
1735 (CodeGen): Property, used to keep track of the code generator.
1737 2001-07-26 Miguel de Icaza <miguel@ximian.com>
1739 * cs-parser.jay: Add a second production for delegate_declaration
1742 (enum_body): Put an opt_comma here instead of putting it on
1743 enum_body or enum_member_declarations so we can handle trailing
1744 commas on enumeration members. Gets rid of a shift/reduce.
1746 (type_list): Need a COMMA in the middle.
1748 (indexer_declaration): Tell tokenizer to recognize get/set
1750 * Remove old targets.
1752 * Re-add the parser target.
1754 2001-07-13 Simon Cozens <simon@simon-cozens.org>
1756 * cs-parser.jay: Add precendence rules for a number of operators
1757 ot reduce the number of shift/reduce conflicts in the grammar.
1759 2001-07-17 Miguel de Icaza <miguel@ximian.com>
1761 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
1764 Get rid of old crufty code.
1766 * rootcontext.cs: Use this to keep track of the parsed
1767 representation and the defined types available to the program.
1769 * gen-treedump.cs: adjust for new convention.
1771 * type.cs: Split out the type manager, and the assembly builder
1774 * typemanager.cs: the type manager will live here now.
1776 * cil-codegen.cs: And the code generator here.

1780 * makefile: Fixed up for easy making.
1782 2001-07-13 Simon Cozens <simon@simon-cozens.org>
1784 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
1787 (unary_expression): Expand pre_increment_expression and
1788 post_decrement_expression to reduce a shift/reduce.
1790 2001-07-11 Simon Cozens
1792 * cs-tokenizer.cs: Hex numbers should begin with a 0.
1794 Improve allow_keyword_as_indent name.
1796 2001-06-19 Miguel de Icaza <miguel@ximian.com>
1798 * Adjustments for Beta2.
1800 2001-06-13 Miguel de Icaza <miguel@ximian.com>
1802 * decl.cs: Added `Define' abstract method.
1803 (InTransit): new property, used to catch recursive definitions.
1805 * interface.cs: Implement `Define'.
1807 * modifiers.cs: Map Modifiers.constants to
1808 System.Reflection.TypeAttribute flags.
1810 * class.cs: Keep track of types and user-defined types.
1811 (BuilderInit): New method for creating an assembly
1812 (ResolveType): New function to launch the resolution process, only
1813 used by interfaces for now.
1815 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
1816 that are inserted into the name space.
1818 2001-06-08 Miguel de Icaza <miguel@ximian.com>
1820 * ARGH. I have screwed up my tree so many times due to the use of
1821 rsync rather than using CVS. Going to fix this at once.
1823 * driver.cs: Objetify driver. Load assemblies, use assemblies to
1826 2001-06-07 Miguel de Icaza <miguel@ximian.com>
1828 * Experiment successful: Use System.Type rather that our own
1831 2001-05-25 Miguel de Icaza <miguel@ximian.com>
1833 * cs-parser.jay: Removed nsAliases from here.
1835 Use new namespaces, handle `using XXX;'
1837 * namespace.cs: Reimplemented namespace handling, use a recursive
1838 definition of the class. Now we can keep track of using clauses
1839 and catch invalid using clauses.
1841 2001-05-24 Miguel de Icaza <miguel@ximian.com>
1843 * gen-treedump.cs: Adapted for all the renaming.
1845 * expression.cs (Expression): this class now has a Type property
1846 which returns an expression Type.
1848 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
1849 `Type', as this has a different meaning now in the base
1851 2001-05-22 Miguel de Icaza <miguel@ximian.com>
1853 * interface.cs, class.cs: Removed from all the sources the
1854 references to signature computation, as we can not do method
1855 signature computation during the parsing time, as we are not
1856 trying to solve at that point distinguishing:
1860 void a (NS.Blah x) {}
1863 Which depending on the context might be valid or not, as we do not
1864 know if Blah is the same thing as NS.Blah at that point.
1866 * Redid everything so the code uses TypeRefs now instead of
1867 Types. TypeRefs are just temporary type placeholders, that need
1868 to be resolved. They initially have a pointer to a string and the
1869 current scope in which they are used. This is used later by the
1870 compiler to resolve the reference to an actual Type.
1872 * DeclSpace is no longer a CIR.Type, and neither are
1873 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
1874 are all DeclSpaces, but no Types.
1876 * type.cs (TypeRefManager): This implements the TypeRef manager,
1877 which keeps track of all the types that need to be resolved after
1878 the parsing has finished.
1880 2001-05-13 Miguel de Icaza <miguel@ximian.com>
1882 * ARGH. We are going to have to store `foreach' as a class rather
1883 than resolving it, as we need to verify error 1579 after name
1884 resolution. *OR* we could keep a flag that says `This request to
1885 IEnumerator comes from a foreach statement' which we can then use
1886 to generate the error.
1888 2001-05-10 Miguel de Icaza <miguel@ximian.com>
1890 * class.cs (TypeContainer.AddMethod): we now add methods to the
1891 MethodGroup instead of the method hashtable.
1893 * expression.cs: Add MethodGroup abstraction, which gets us one
1894 step closer to the specification in the way we handle method
1897 * cs-parser.jay (primary_expression): qualified_identifier now
1898 tried to match up an identifier to a local variable reference or
1899 to a parameter reference.
1901 current_local_parameters is now a parser global variable that
1902 points to the current parameters for the block, used during name
1905 (property_declaration): Now creates an implicit `value' argument to
1908 2001-05-09 Miguel de Icaza <miguel@ximian.com>
1910 * parameter.cs: Do not use `param' arguments as part of the
1911 signature, per the spec.
1913 2001-05-08 Miguel de Icaza <miguel@ximian.com>
1915 * decl.cs: Base class for classes, structs and interfaces. This
1916 is the "Declaration Space"
1918 * cs-parser.jay: Use CheckDef for checking declaration errors
1919 instead of having one on each function.
1921 * class.cs: Factor out some code for handling error handling in
1922 accordance to the "Declarations" section in the "Basic Concepts"
1923 chapter in the ECMA C# spec.
1925 * interface.cs: Make all interface member classes derive from
1926 InterfaceMemberBase.
1928 2001-05-07 Miguel de Icaza <miguel@ximian.com>
1930 * Many things: all interfaces are parsed and generated in
1931 gen-treedump. Support for member variables, constructors,
1932 destructors, properties, constants is there.
1934 Beginning of the IL backend, but very little done, just there for
1937 2001-04-29 Miguel de Icaza <miguel@ximian.com>
1939 * cs-parser.jay: Fix labeled statement.
1941 * cs-tokenizer.cs (escape): Escape " and ' always.
1942 ref_line, ref_name: keep track of the line/filename as instructed
1943 by #line by the compiler.
1946 2001-04-27 Miguel de Icaza <miguel@ximian.com>
1948 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
1949 to match the values in System.CodeDOM.
1951 Divid renamed to Divide.
1953 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
1955 (Statements.set): remove.
1957 * System.CodeDOM/CodeCatchClause.cs: always have a valid
1960 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
1961 falseStatements always have valid values.
1963 * cs-parser.jay: Use System.CodeDOM now.
