1 2001-10-01 Miguel de Icaza <miguel@ximian.com>
3 * expression.cs (Expression::ExprClassFromMemberInfo,
4 Expression::Literalize): Create literal expressions from
5 FieldInfos which are literals.
7 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
8 type casts, because they were wrong. The test suite in tests
11 (ImplicitNumericConversion): ushort to ulong requires a widening
14 Int32 constant to long requires widening cast as well.
16 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
17 for integers because the type on the stack is not i4.
19 2001-09-30 Miguel de Icaza <miguel@ximian.com>
21 * expression.cs (report118): require location argument.
23 * parameter.cs: Do not dereference potential null value.
25 * class.cs: Catch methods that lack the `new' keyword when
26 overriding a name. Report warnings when `new' is used without
27 anything being there to override.
29 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
31 * class.cs: Only add constructor to hashtable if it is non-null
32 (as now constructors can fail on define).
34 (TypeManager, Class, Struct): Take location arguments.
36 Catch field instance initialization in structs as errors.
38 accepting_filter: a new filter for FindMembers that is static so
39 that we dont create an instance per invocation.
41 (Constructor::Define): Catch errors where a struct constructor is
44 * cs-parser.jay: Pass location information for various new
47 * delegate.cs (Delegate): take a location argument.
49 * driver.cs: Do not call EmitCode if there were problesm in the
50 Definition of the types, as many Builders wont be there.
52 * decl.cs (Decl::Decl): Require a location argument.
54 * cs-tokenizer.cs: Handle properly hex constants that can not fit
55 into integers, and find the most appropiate integer for it.
57 * literal.cs: Implement ULongLiteral.
59 * rootcontext.cs: Provide better information about the location of
60 failure when CreateType fails.
62 2001-09-29 Miguel de Icaza <miguel@ximian.com>
64 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
67 * expression.cs (Binary::CheckShiftArguments): Add missing type
69 (Binary::ResolveOperator): Add type to the logical and and logical
70 or, Bitwise And/Or and Exclusive Or code paths, it was missing
73 (Binary::DoNumericPromotions): In the case where either argument
74 is ulong (and most signed types combined with ulong cause an
75 error) perform implicit integer constant conversions as well.
77 2001-09-28 Miguel de Icaza <miguel@ximian.com>
79 * expression.cs (UserImplicitCast): Method should always be
81 (Invocation::BetterConversion): Simplified test for IntLiteral.
83 (Expression::ImplicitNumericConversion): Split this routine out.
84 Put the code that performs implicit constant integer conversions
87 (Expression::Resolve): Become a wrapper around DoResolve so we can
88 check eclass and type being set after resolve.
90 (Invocation::Badness): Remove this dead function
92 (Binary::ResolveOperator): Do not compute the expensive argumnets
93 unless we have a union for it.
95 (Probe::Emit): Is needs to do an isinst and then
98 (::CanConvert): Added Location argument. If the Location argument
99 is null (Location.Null), then we do not report errors. This is
100 used by the `probe' mechanism of the Explicit conversion. We do
101 not want to generate an error for something that the user
102 explicitly requested to be casted. But the pipeline for an
103 explicit cast first tests for potential implicit casts.
105 So for now, if the Location is null, it means `Probe only' to
106 avoid adding another argument. Might have to revise this
109 (ClassCast): New class used to type cast objects into arbitrary
110 classes (used in Explicit Reference Conversions).
112 Implement `as' as well.
114 Reverted all the patches from Ravi below: they were broken:
116 * The use of `level' as a mechanism to stop recursive
117 invocations is wrong. That was there just to catch the
118 bug with a strack trace but not as a way of addressing
121 To fix the problem we have to *understand* what is going
122 on and the interactions and come up with a plan, not
123 just get things going.
125 * The use of the type conversion cache that I proposed
126 last night had an open topic: How does this work across
127 protection domains. A user defined conversion might not
128 be public in the location where we are applying the
129 conversion, a different conversion might be selected
130 (ie, private A->B (better) but public B->A (worse),
131 inside A, A->B applies, but outside it, B->A will
134 * On top of that (ie, even if the above is solved),
135 conversions in a cache need to be abstract. Ie, `To
136 convert from an Int to a Short use an OpcodeCast', not
137 `To convert from an Int to a Short use the OpcodeCast on
138 the variable 5' (which is what this patch was doing).
140 2001-09-28 Ravi Pratap <ravi@ximian.com>
142 * expression.cs (Invocation::ConversionExists): Re-write to use
145 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
146 cache all conversions done, not just user-defined ones.
148 (Invocation::BetterConversion): The real culprit. Use ConversionExists
149 to determine if a conversion exists instead of acutually trying to
150 perform the conversion. It's faster too.
152 (Expression::ConvertExplicit): Modify to use ConversionExists to check
153 and only then attempt the implicit conversion.
155 2001-09-28 Ravi Pratap <ravi@ximian.com>
157 * expression.cs (ConvertImplicit): Use a cache for conversions
158 already found. Check level of recursion and bail out if necessary.
160 2001-09-28 Miguel de Icaza <miguel@ximian.com>
162 * typemanager.cs (string_concat_string_string, string_concat_object_object):
163 Export standard methods that we expect for string operations.
165 * statement.cs (Block::UsageWarning): Track usage of variables and
166 report the errors for not used variables.
168 * expression.cs (Conditional::Resolve, ::Emit): Implement ?:
171 2001-09-27 Miguel de Icaza <miguel@ximian.com>
173 * codegen.cs: remove unnneded code
175 * expression.cs: Removed BuiltinTypeAccess class
177 Fix the order in which implicit conversions are
180 The previous fixed dropped support for boxed conversions (adding a
181 test to the test suite now)
183 (UserImplicitCast::CanConvert): Remove test for source being null,
184 that code is broken. We should not feed a null to begin with, if
185 we do, then we should track the bug where the problem originates
186 and not try to cover it up here.
188 Return a resolved expression of type UserImplicitCast on success
189 rather than true/false. Ravi: this is what I was talking about,
190 the pattern is to use a static method as a "constructor" for
193 Also, do not create arguments until the very last minute,
194 otherwise we always create the arguments even for lookups that
195 will never be performed.
197 (UserImplicitCast::Resolve): Eliminate, objects of type
198 UserImplicitCast are born in a fully resolved state.
200 * typemanager.cs (InitCoreTypes): Init also value_type
203 * expression.cs (Cast::Resolve): First resolve the child expression.
205 (LValue): Add new method AddressOf to be used by
208 Change the argument of Store to take an EmitContext instead of an
209 ILGenerator, because things like FieldExpr need to be able to call
210 their children expression to generate the instance code.
212 (Expression::Error, Expression::Warning): Sugar functions for
215 (Expression::MemberLookup): Accept a TypeContainer instead of a
216 Report as the first argument.
218 (Expression::ResolvePrimary): Killed. I still want to improve
219 this as currently the code is just not right.
221 (Expression::ResolveMemberAccess): Simplify, but it is still
224 (Unary::Resolve): Catch errors in AddressOf operators.
226 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
227 index to a byte for the short-version, or the compiler will choose
228 the wrong Emit call, which generates the wrong data.
230 (ParameterReference::Emit, ::Store): same.
232 (FieldExpr::AddressOf): Implement.
234 * typemanager.cs: TypeManager: made public variable instead of
237 * driver.cs: document --fatal.
239 * report.cs (ErrorMessage, WarningMessage): new names for the old
240 Error and Warning classes.
242 * cs-parser.jay (member_access): Turn built-in access to types
243 into a normal simplename
245 2001-09-27 Ravi Pratap <ravi@ximian.com>
247 * expression.cs (Invocation::BetterConversion): Fix to cope
248 with q being null, since this was introducing a bug.

254 * expression.cs (UserImplicitCast::Resolve): Fix bug.
256 2001-09-27 Ravi Pratap <ravi@ximian.com>
258 * class.cs (TypeContainer::AddConstructor): Fix a stupid bug
259 I had introduced long ago (what's new ?).
261 * expression.cs (UserImplicitCast::CanConvert): Static method to do
262 the work of all the checking.
263 (ConvertImplicit): Call CanConvert and only then create object if necessary.
264 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
266 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
267 that is the right way.
269 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
270 overloading resolution. Use everywhere instead of cutting and pasting code.
272 (Binary::ResolveOperator): Use MakeUnionSet.
274 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
275 we have to convert to bool types. Not complete yet.
277 2001-09-27 Miguel de Icaza <miguel@ximian.com>
279 * typemanager.cs (TypeManager::CSharpName): support ushort.
281 * expression.cs (Expression::TryImplicitIntConversion): Attempts
282 to provide an expression that performsn an implicit constant int
283 conversion (section 6.1.6).
284 (Expression::ConvertImplicitRequired): Reworked to include
285 implicit constant expression conversions.
287 (Expression::ConvertNumericExplicit): Finished.
289 (Invocation::Emit): If InstanceExpression is null, then it means
290 that we perform a call on this.
292 2001-09-26 Miguel de Icaza <miguel@ximian.com>
294 * expression.cs (Unary::Emit): Remove some dead code.
295 (Probe): Implement Resolve and Emit for `is'.
296 (Expression::ConvertImplicitRequired): Attempt to do constant
297 expression conversions here. Maybe should be moved to
298 ConvertImplicit, but I am not sure.
299 (Expression::ImplicitLongConstantConversionPossible,
300 Expression::ImplicitIntConstantConversionPossible): New functions
301 that tell whether is it possible to apply an implicit constant
302 expression conversion.
304 (ConvertNumericExplicit): Started work on explicit numeric
307 * cs-parser.jay: Update operator constants.
309 * parameter.cs (Parameters::GetParameterInfo): Hook up VerifyArgs

311 (Parameters::VerifyArgs): Verifies that no two arguments have the
314 * class.cs (Operator): Update the operator names to reflect the
315 ones that the spec expects (as we are just stringizing the
318 * expression.cs (Unary::ResolveOperator): Fix bug: Use
319 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
320 previous usage did only work for our methods.
321 (Expression::ConvertImplicit): Handle decimal implicit numeric
323 (Expression::InternalTypeConstructor): Used to invoke constructors
324 on internal types for default promotions.
326 (Unary::Emit): Implement special handling for the pre/post
327 increment/decrement for overloaded operators, as they need to have
328 the same semantics as the other operators.
330 (Binary::ResolveOperator): ditto.
331 (Invocation::ConversionExists): ditto.
332 (UserImplicitCast::Resolve): ditto.
334 2001-09-26 Ravi Pratap <ravi@ximian.com>

348 * assign.cs (Assign): Make it inherit from ExpressionStatement.
350 * expression.cs (ExpressionStatement): New base class used for
351 expressions that can appear in statements, so that we can provide
352 an alternate path to generate expression that do not leave a value
355 (Expression::Emit, and all the derivatives): We no longer return
356 whether a value is left on the stack or not. Every expression
357 after being emitted leaves a single value on the stack.
359 * codegen.cs (EmitContext::EmitStatementExpression): Use the
360 facilties of ExpressionStatement if possible.
362 * cs-parser.jay: Update statement_expression.

387 * assign.cs: track location.
388 (Resolve): Use implicit conversions on assignment.
390 * literal.cs: Oops. Not good, Emit of short access values should
391 pass (Bytes) or the wrong argument will be selected.
393 * expression.cs (Unary::Emit): Emit code for -expr.
395 (Unary::ResolveOperator): Handle `Substract' for non-constants
396 (substract from zero from the non-constants).

434 * All over : Pass in TypeContainer as argument to OverloadResolve.
436 * typemanager.cs (CSharpName): Update to check for the string type and return
439 * expression.cs (Invocation::FullMethodDesc): New static method to return a string fully describing

453 * typemanager.cs: declare and load enum_type, delegate_type and
456 * expression.cs (Expression::Emit): Now emit returns a value that
457 tells whether a value is left on the stack or not. This strategy
458 might be reveted tomorrow with a mechanism that would address
459 multiple assignments.
460 (Expression::report118): Utility routine to report mismatches on
463 (Unary::Report23): Report impossible type/operator combination

474 * All Expression derivatives: Updated their Emit method to return
475 whether they leave values on the stack or not.
477 * codegen.cs (CodeGen::EmitStatement): Pop values left on the
478 stack for expressions that are statements.
480 2001-09-20 Miguel de Icaza <miguel@ximian.com>
482 * expression.cs (LValue): New interface. Must be implemented by

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

559 Binary::ResolveOperator does for Binary expressions.
560 (Unary.method, .Arguments): Add.
561 (Unary::OperName): Implement.
562 (Unary::ForceConversion): Copy and Paste !
564 * class.cs (Operator::Define): Fix a small bug for the case when we have
567 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
568 for the inbuilt operators. Only overloading works for now ;-)
570 2001-09-18 Miguel de Icaza <miguel@ximian.com>

588 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
589 the last instruction contains a return opcode to avoid generating
590 the last `ret' instruction (this generates correct code, and it is
591 nice to pass the peverify output).
593 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
594 initializer for static and instance variables.
595 (Constructor::Emit): Allow initializer to be null in the case of
596 static constructors. Only emit initializer for instance

611 * cs-parser.jay (constructor_declaration): Provide default base

614 initializers if none was specified.
615 Catch the fact that constructors should not have parameters.
617 * class.cs: Do not emit parent class initializers for static
618 constructors, that should be flagged as an error.
620 2001-09-18 Ravi Pratap <ravi@ximian.com>
622 * class.cs (RegisterMethodBuilder): Remove : it's unnecessary.
623 Move back code into TypeContainer::Populate.

649 * expression.cs (Expression::OverloadResolve): Drop TypeContainer
652 (Expression::MemberLookup): Provide a version that allows to
653 specify the MemberTypes and BindingFlags.

661 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200

665 (TypeContainer::EmitDefaultConstructor): Removed routine, now we
666 deal with this by semantically definining it as if the user had
669 (TypeContainer::FindMembers): Removed ad-hoc hack to deal with
670 constructors as we now "emit" them at a higher level.
672 (TypeContainer::DefineDefaultConstructor): Used to define the
673 default constructors if none was provided.
675 (ConstructorInitializer): Add methods Resolve and Emit.

723 if we have no work to do.
724 (TypeContainer::Emit): Pass in TypeContainer as argument to the constructor's
727 * interface.cs (Interface::InterfaceAttr): Re-write to be more correct and complete.
728 (Interface::IsTopLevel): Add. Same as TypeContainer::IsTopLevel.
730 * class.cs (TypeContainer::IsTopLevel): Modify to use parent.Parent instead

740 * cs-parser.jay (namespace_declaration): Call RecordNamespace to
743 * rootcontext.cs (IsNamespace): Fixed it :-)
745 2001-09-14 Miguel de Icaza <miguel@ximian.com>

754 Load System assembly as well as part of the standard library.
756 * report.cs: Allow throwing exceptions on errors for debugging.
758 * modifiers.cs: Do not use `parent', instead use the real type
759 container to evaluate permission settings.
761 * class.cs: Put Ravi's patch back in. He is right, and we will
762 have to cope with the
764 2001-09-14 Ravi Pratap <ravi@ximian.com>
766 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to

771 * driver.cs: Added --parse option that only parses its input files
774 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
775 incorrect. IsTopLevel is not used to tell whether an object is
776 root_types or not (that can be achieved by testing this ==
777 root_types). But to see if this is a top-level *class* (not
778 necessarly our "toplevel" container).
780 2001-09-14 Ravi Pratap <ravi@ximian.com>
782 * enum.cs (Enum::Define): Modify to call the Lookup method on the
783 parent instead of a direct call to GetType.
785 2001-09-14 Ravi Pratap <ravi@ximian.com>
787 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into

804 * modifiers.cs (MethodAttr): Re-write.
805 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
807 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
808 of top-level types as claimed.
810 2001-09-13 Miguel de Icaza <miguel@ximian.com>
812 * expression.cs (MemberLookup): Fruitless attempt to lookup
813 constructors. Maybe I need to emit default constructors? That
814 might be it (currently .NET emits this for me automatically).
815 (Invocation::OverloadResolve): Cope with Arguments == null.
816 (Invocation::EmitArguments): new function, shared by the new

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

850 (Binary::ResolveOperator): Set the return type to boolean for
851 comparission operators
853 * typemanager.cs: Remove debugging print code.
855 (Invocation::Resolve): resolve type.
857 * class.cs: Allocate a MemberInfo of the correct size, as the code
858 elsewhere depends on the test to reflect the correct contents.
860 (Method::) Keep track of parameters, due to System.Reflection holes
862 (TypeContainer::Populate): Keep track of MethodBuilders to Method
865 (TypeContainer::FindMembers): Use ArrayList and then copy an array
866 of the exact size and return that.
868 (Class::LookupMethodByBuilder): New function that maps
869 MethodBuilders to its methods. Required to locate the information
870 on methods because System.Reflection bit us again.
872 * support.cs: New file, contains an interface ParameterData and
873 two implementations: ReflectionParameters and InternalParameters
874 used to access Parameter information. We will need to grow this
877 * expression.cs (Invocation::GetParameterData): implement a cache
878 and a wrapper around the ParameterData creation for methods.

892 initialized with the full type once it is resolved.
894 2001-09-12 Miguel de Icaza <miguel@ximian.com>
896 * parameter.cs (GetParameterInfo): Use a type cache to compute
897 things only once, and to reuse this information

900 (OpcodeCast::Emit): fix.
902 (ParameterReference::Resolve): Implement.

941 * typemanager.cs (typecontainers): New hashtable to hold the corresponding
942 typecontainer objects as we need to get at them.
943 (TypeManager::AddUserType): Overload to take an extra argument, the TypeContainer.

949 of just a Report object.
951 2001-09-11 Ravi Pratap <ravi@ximian.com>

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

1358 * cs-parser.jay (general_catch_clause): Comment out
1359 (specific_catch_clauses, specific_catch_clause): Ditto.
1360 (opt_general_catch_clause, opt_specific_catch_clauses): Ditto
1361 (catch_args, opt_catch_args): New productions.
1362 (catch_clause): Rewrite to use the new productions above
1363 (catch_clauses): Modify accordingly.
1364 (opt_catch_clauses): New production to use in try_statement
1365 (try_statement): Revamp. Basically, we get rid of one unnecessary rule
1366 and re-write the code in the actions to extract the specific and
1367 general catch clauses by being a little smart ;-)
1369 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
1370 Hooray, try and catch statements parse fine !
1372 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
1374 * statement.cs (Block::GetVariableType): Fix logic to extract the type
1375 string from the hashtable of variables.
1377 * cs-parser.jay (event_accessor_declarations): Trivial fix. Man, how did
1378 I end up making that mistake ;-)
1379 (catch_clauses): Fixed gross error which made Key and Value of the
1380 DictionaryEntry the same : $1 !!
1382 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
1384 * cs-tokenizer.cs (initTokens): Add keywords 'add' and 'remove'
1386 * cs-parser.jay (event_declaration): Correct to remove the semicolon
1387 when the add and remove accessors are specified.
1389 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
1391 * cs-parser.jay (IndexerDeclaration): New helper class to hold
1392 information about indexer_declarator.
1393 (indexer_declarator): Implement actions.
1394 (parsing_indexer): New local boolean used to keep track of whether
1395 we are parsing indexers or properties. This is necessary because
1396 implicit_parameters come into picture even for the get accessor in the
1398 (get_accessor_declaration, set_accessor_declaration): Correspondingly modified.
1400 * class.cs (Indexer): New class for indexer declarations.
1401 (TypeContainer::AddIndexer): New method to add an indexer to a type.
1402 (TypeContainer::indexers): New member to hold list of indexers for the
1405 2001-08-27 Ravi Pratap <ravi@che.iitm.ac.in>
1407 * cs-parser.jay (add_accessor_declaration): Implement action.
1408 (remove_accessor_declaration): Implement action.
1409 (event_accessors_declaration): Implement
1410 (variable_declarators): swap statements for first rule - trivial.
1412 * class.cs (Event): New class to hold information about event
1414 (TypeContainer::AddEvent): New method to add an event to a type
1415 (TypeContainer::events): New member to hold list of events.
1417 * cs-parser.jay (event_declaration): Implement actions.
1419 2001-08-27 Ravi Pratap <ravi@che.iitm.ac.in>
1421 * cs-parser.jay (dim_separators): Implement. Make it a string
1422 concatenating all the commas together, just as they appear.
1423 (opt_dim_separators): Modify accordingly
1424 (rank_specifiers): Update accordingly. Basically do the same
1425 thing - instead, collect the brackets here.
1426 (opt_rank_sepcifiers): Modify accordingly.
1427 (array_type): Modify to actually return the complete type string
1428 instead of ignoring the rank_specifiers.
1429 (expression_list): Implement to collect the expressions
1430 (variable_initializer): Implement. We make it a list of expressions
1431 essentially so that we can handle the array_initializer case neatly too.
1432 (variable_initializer_list): Implement.
1433 (array_initializer): Make it a list of variable_initializers
1434 (opt_array_initializer): Modify accordingly.
1436 * expression.cs (New::NType): Add enumeration to help us
1437 keep track of whether we have an object/delegate creation
1438 or an array creation.
1439 (New:NewType, New::Rank, New::Indices, New::Initializers): New
1440 members to hold data about array creation.
1441 (New:New): Modify to update NewType
1442 (New:New): New Overloaded contructor for the array creation
1445 * cs-parser.jay (array_creation_expression): Implement to call
1446 the overloaded New constructor.
1448 2001-08-26 Ravi Pratap <ravi@che.iitm.ac.in>
1450 * class.cs (TypeContainer::Constructors): Return member
1451 constructors instead of returning null.
1453 2001-08-26 Miguel de Icaza <miguel@ximian.com>
1455 * typemanager.cs (InitCoreTypes): Initialize the various core
1456 types after we have populated the type manager with the user
1457 defined types (this distinction will be important later while
1458 compiling corlib.dll)
1460 * expression.cs, literal.cs, assign.cs, constant.cs: Started work
1461 on Expression Classification. Now all expressions have a method
1462 `Resolve' and a method `Emit'.
1464 * codegen.cs, cs-parser.jay: Fixed the bug that stopped code
1465 generation from working. Also add some temporary debugging
1468 2001-08-24 Miguel de Icaza <miguel@ximian.com>
1470 * codegen.cs: Lots of code generation pieces. This is only the
1471 beginning, will continue tomorrow with more touches of polish. We
1472 handle the fundamentals of if, while, do, for, return. Others are
1473 trickier and I need to start working on invocations soon.
1475 * gen-treedump.cs: Bug fix, use s.Increment here instead of
1478 * codegen.cs (EmitContext): New struct, used during code
1479 emission to keep a context. Most of the code generation will be
1482 * cs-parser.jay: Add embedded blocks to the list of statements of
1483 this block. So code generation proceeds in a top down fashion.
1485 2001-08-23 Miguel de Icaza <miguel@ximian.com>
1487 * statement.cs: Add support for multiple child blocks.
1489 2001-08-22 Miguel de Icaza <miguel@ximian.com>
1491 * codegen.cs (EmitCode): New function, will emit the code for a
1492 Block of code given a TypeContainer and its ILGenerator.
1494 * statement.cs (Block): Standard public readonly optimization.
1495 (Block::Block constructors): Link children.
1496 (Block::Child): Child Linker.
1497 (Block::EmitVariables): Emits IL variable declarations.
1499 * class.cs: Drop support for MethodGroups here, delay until
1501 (Method::): Applied the same simplification that I did before, and
1502 move from Properties to public readonly fields.
1503 (Method::ParameterTypes): Returns the parameter types for the
1504 function, and implements a cache that will be useful later when I
1505 do error checking and the semantic analysis on the methods is
1507 (Constructor::GetCallingConvention): Renamed from CallingConvetion
1508 and made a method, optional argument tells whether this is a class
1509 or a structure to apply the `has-this' bit.
1510 (Method::GetCallingConvention): Implement, returns the calling
1512 (Method::Define): Defines the type, a second pass is performed
1513 later to populate the methods.
1515 (Constructor::ParameterTypes): implement a cache similar to the
1516 one on Method::ParameterTypes, useful later when we do semantic
1519 (TypeContainer::EmitMethod): New method. Emits methods.
1521 * expression.cs: Removed MethodGroup class from here.
1523 * parameter.cs (Parameters::GetCallingConvention): new method.
1525 2001-08-21 Miguel de Icaza <miguel@ximian.com>
1527 * class.cs (TypeContainer::Populate): Drop RootContext from the
1530 (Constructor::CallingConvention): Returns the calling convention.
1531 (Constructor::ParameterTypes): Returns the constructor parameter
1534 (TypeContainer::AddConstructor): Keep track of default constructor
1535 and the default static constructor.
1537 (Constructor::) Another class that starts using `public readonly'
1538 instead of properties.
1540 (Constructor::IsDefault): Whether this is a default constructor.
1542 (Field::) use readonly public fields instead of properties also.
1544 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
1545 track of static constructors; If none is used, turn on
1546 BeforeFieldInit in the TypeAttributes.
1548 * cs-parser.jay (opt_argument_list): now the return can be null
1549 for the cases where there are no arguments.
1551 (constructor_declarator): If there is no implicit `base' or
1552 `this', then invoke the default parent constructor.
1554 * modifiers.cs (MethodAttr): New static function maps a set of
1555 modifiers flags into a MethodAttributes enum
1556 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
1557 MethodAttr, TypeAttr to represent the various mappings where the
1559 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
1561 2001-08-19 Miguel de Icaza <miguel@ximian.com>
1563 * parameter.cs (GetParameterInfo): Fix bug where there would be no
1566 * interface.cs (PopulateIndexer): Implemented the code generator
1567 for interface indexers.
1569 2001-08-17 Miguel de Icaza <miguel@ximian.com>
1571 * interface.cs (InterfaceMemberBase): Now we track the new status
1574 (PopulateProperty): Implement property population. Woohoo! Got
1575 Methods and Properties going today.
1577 Removed all the properties for interfaces, and replaced them with
1578 `public readonly' fields.
1580 2001-08-16 Miguel de Icaza <miguel@ximian.com>
1582 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
1583 initialize their hashtables/arraylists only when they are needed
1584 instead of doing this always.
1586 * parameter.cs: Handle refs and out parameters.
1588 * cs-parser.jay: Use an ArrayList to construct the arguments
1589 instead of the ParameterCollection, and then cast that to a
1592 * parameter.cs: Drop the use of ParameterCollection and use
1593 instead arrays of Parameters.
1595 (GetParameterInfo): Use the Type, not the Name when resolving
1598 2001-08-13 Miguel de Icaza <miguel@ximian.com>
1600 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
1601 and instead use public readonly fields.
1603 * class.cs: Put back walking code for type containers.
1605 2001-08-11 Miguel de Icaza <miguel@ximian.com>
1607 * class.cs (MakeConstant): Code to define constants.
1609 * rootcontext.cs (LookupType): New function. Used to locate types
1612 2001-08-08 Miguel de Icaza <miguel@ximian.com>
1614 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
1615 this System.Reflection code is. Kudos to Microsoft
1617 * typemanager.cs: Implement a type cache and avoid loading all
1618 types at boot time. Wrap in LookupType the internals. This made
1619 the compiler so much faster. Wow. I rule!
1621 * driver.cs: Make sure we always load mscorlib first (for
1622 debugging purposes, nothing really important).
1624 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
1625 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
1627 * rootcontext.cs: Lookup types on their namespace; Lookup types
1628 on namespaces that have been imported using the `using' keyword.
1630 * class.cs (TypeContainer::TypeAttr): Virtualize.
1631 (Class::TypeAttr): Return attributes suitable for this bad boy.
1632 (Struct::TypeAttr): ditto.
1633 Handle nested classes.
1634 (TypeContainer::) Remove all the type visiting code, it is now
1635 replaced with the rootcontext.cs code
1637 * rootcontext.cs (GetClassBases): Added support for structs.
1639 2001-08-06 Miguel de Icaza <miguel@ximian.com>
1641 * interface.cs, statement.cs, class.cs, parameter.cs,
1642 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
1643 Drop use of TypeRefs, and use strings instead.
1645 2001-08-04 Miguel de Icaza <miguel@ximian.com>
1649 * class.cs (Struct::Struct): set the SEALED flags after
1650 checking the modifiers.
1651 (TypeContainer::TypeAttr): new property, returns the
1652 TypeAttributes for a class.
1654 * cs-parser.jay (type_list): Oops, list production was creating a
1655 new list of base types.
1657 * rootcontext.cs (StdLib): New property.
1658 (GetInterfaceTypeByName): returns an interface by type name, and
1659 encapsulates error handling here.
1660 (GetInterfaces): simplified.
1661 (ResolveTree): Encapsulated all the tree resolution here.
1662 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
1665 * driver.cs: Add support for --nostdlib, to avoid loading the
1667 (Main): Do not put tree resolution here.
1669 * rootcontext.cs: Beginning of the class resolution.
1671 2001-08-03 Miguel de Icaza <miguel@ximian.com>
1673 * rootcontext.cs: Provide better error reporting.
1675 * cs-parser.jay (interface_base): set our $$ to be interfaces.
1677 * rootcontext.cs (CreateInterface): Handle the case where there
1678 are no parent interfaces.
1680 (CloseTypes): Routine to flush types at the end.
1681 (CreateInterface): Track types.
1682 (GetInterfaces): Returns an array of Types from the list of
1685 * typemanager.c (AddUserType): Mechanism to track user types (puts
1686 the type on the global type hash, and allows us to close it at the
1689 2001-08-02 Miguel de Icaza <miguel@ximian.com>
1691 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
1692 RecordInterface instead.
1694 * cs-parser.jay: Updated to reflect changes above.
1696 * decl.cs (Definition): Keep track of the TypeBuilder type that
1697 represents this type here. Not sure we will use it in the long
1698 run, but wont hurt for now.
1700 * driver.cs: Smaller changes to accomodate the new code.
1702 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
1705 * rootcontext.cs (CreateInterface): New method, used to create
1706 the System.TypeBuilder type for interfaces.
1707 (ResolveInterfaces): new entry point to resolve the interface
1709 (CodeGen): Property, used to keep track of the code generator.
1711 2001-07-26 Miguel de Icaza <miguel@ximian.com>
1713 * cs-parser.jay: Add a second production for delegate_declaration
1716 (enum_body): Put an opt_comma here instead of putting it on
1717 enum_body or enum_member_declarations so we can handle trailing
1718 commas on enumeration members. Gets rid of a shift/reduce.
1720 (type_list): Need a COMMA in the middle.
1722 (indexer_declaration): Tell tokenizer to recognize get/set
1724 * Remove old targets.
1726 * Re-add the parser target.
1728 2001-07-13 Simon Cozens <simon@simon-cozens.org>
1730 * cs-parser.jay: Add precendence rules for a number of operators
1731 ot reduce the number of shift/reduce conflicts in the grammar.
1733 2001-07-17 Miguel de Icaza <miguel@ximian.com>
1735 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
1738 Get rid of old crufty code.
1740 * rootcontext.cs: Use this to keep track of the parsed
1741 representation and the defined types available to the program.
1743 * gen-treedump.cs: adjust for new convention.
1745 * type.cs: Split out the type manager, and the assembly builder
1748 * typemanager.cs: the type manager will live here now.
1750 * cil-codegen.cs: And the code generator here.
1752 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
1754 * makefile: Fixed up for easy making.
1756 2001-07-13 Simon Cozens <simon@simon-cozens.org>
1758 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
1761 (unary_expression): Expand pre_increment_expression and
1762 post_decrement_expression to reduce a shift/reduce.
1764 2001-07-11 Simon Cozens
1766 * cs-tokenizer.cs: Hex numbers should begin with a 0.
1768 Improve allow_keyword_as_indent name.
1770 2001-06-19 Miguel de Icaza <miguel@ximian.com>
1772 * Adjustments for Beta2.
1774 2001-06-13 Miguel de Icaza <miguel@ximian.com>
1776 * decl.cs: Added `Define' abstract method.
1777 (InTransit): new property, used to catch recursive definitions.
1779 * interface.cs: Implement `Define'.
1781 * modifiers.cs: Map Modifiers.constants to
1782 System.Reflection.TypeAttribute flags.
1784 * class.cs: Keep track of types and user-defined types.
1785 (BuilderInit): New method for creating an assembly
1786 (ResolveType): New function to launch the resolution process, only
1787 used by interfaces for now.
1789 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
1790 that are inserted into the name space.
1792 2001-06-08 Miguel de Icaza <miguel@ximian.com>
1794 * ARGH. I have screwed up my tree so many times due to the use of
1795 rsync rather than using CVS. Going to fix this at once.
1797 * driver.cs: Objetify driver. Load assemblies, use assemblies to
1800 2001-06-07 Miguel de Icaza <miguel@ximian.com>
1802 * Experiment successful: Use System.Type rather that our own
1805 2001-05-25 Miguel de Icaza <miguel@ximian.com>
1807 * cs-parser.jay: Removed nsAliases from here.
1809 Use new namespaces, handle `using XXX;'
1811 * namespace.cs: Reimplemented namespace handling, use a recursive
1812 definition of the class. Now we can keep track of using clauses
1813 and catch invalid using clauses.
1815 2001-05-24 Miguel de Icaza <miguel@ximian.com>
1817 * gen-treedump.cs: Adapted for all the renaming.
1819 * expression.cs (Expression): this class now has a Type property
1820 which returns an expression Type.
1822 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
1823 `Type', as this has a different meaning now in the base
1825 2001-05-22 Miguel de Icaza <miguel@ximian.com>
1827 * interface.cs, class.cs: Removed from all the sources the
1828 references to signature computation, as we can not do method
1829 signature computation during the parsing time, as we are not
1830 trying to solve at that point distinguishing:
1834 void a (NS.Blah x) {}
1837 Which depending on the context might be valid or not, as we do not
1838 know if Blah is the same thing as NS.Blah at that point.
1840 * Redid everything so the code uses TypeRefs now instead of
1841 Types. TypeRefs are just temporary type placeholders, that need
1842 to be resolved. They initially have a pointer to a string and the
1843 current scope in which they are used. This is used later by the
1844 compiler to resolve the reference to an actual Type.
1846 * DeclSpace is no longer a CIR.Type, and neither are
1847 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
1848 are all DeclSpaces, but no Types.
1850 * type.cs (TypeRefManager): This implements the TypeRef manager,
1851 which keeps track of all the types that need to be resolved after
1852 the parsing has finished.
1854 2001-05-13 Miguel de Icaza <miguel@ximian.com>
1856 * ARGH. We are going to have to store `foreach' as a class rather
1857 than resolving it, as we need to verify error 1579 after name
1858 resolution. *OR* we could keep a flag that says `This request to
1859 IEnumerator comes from a foreach statement' which we can then use
1860 to generate the error.
1862 2001-05-10 Miguel de Icaza <miguel@ximian.com>
1864 * class.cs (TypeContainer.AddMethod): we now add methods to the
1865 MethodGroup instead of the method hashtable.
1867 * expression.cs: Add MethodGroup abstraction, which gets us one
1868 step closer to the specification in the way we handle method
1871 * cs-parser.jay (primary_expression): qualified_identifier now
1872 tried to match up an identifier to a local variable reference or
1873 to a parameter reference.
1875 current_local_parameters is now a parser global variable that
1876 points to the current parameters for the block, used during name
1879 (property_declaration): Now creates an implicit `value' argument to
1882 2001-05-09 Miguel de Icaza <miguel@ximian.com>
1884 * parameter.cs: Do not use `param' arguments as part of the
1885 signature, per the spec.
1887 2001-05-08 Miguel de Icaza <miguel@ximian.com>
1889 * decl.cs: Base class for classes, structs and interfaces. This
1890 is the "Declaration Space"
1892 * cs-parser.jay: Use CheckDef for checking declaration errors
1893 instead of having one on each function.
1895 * class.cs: Factor out some code for handling error handling in
1896 accordance to the "Declarations" section in the "Basic Concepts"
1897 chapter in the ECMA C# spec.
1899 * interface.cs: Make all interface member classes derive from
1900 InterfaceMemberBase.
1902 2001-05-07 Miguel de Icaza <miguel@ximian.com>
1904 * Many things: all interfaces are parsed and generated in
1905 gen-treedump. Support for member variables, constructors,
1906 destructors, properties, constants is there.
1908 Beginning of the IL backend, but very little done, just there for
1911 2001-04-29 Miguel de Icaza <miguel@ximian.com>
1913 * cs-parser.jay: Fix labeled statement.
1915 * cs-tokenizer.cs (escape): Escape " and ' always.
1916 ref_line, ref_name: keep track of the line/filename as instructed
1917 by #line by the compiler.
1920 2001-04-27 Miguel de Icaza <miguel@ximian.com>
1922 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
1923 to match the values in System.CodeDOM.
1925 Divid renamed to Divide.
1927 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
1929 (Statements.set): remove.
1931 * System.CodeDOM/CodeCatchClause.cs: always have a valid
1934 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
1935 falseStatements always have valid values.
1937 * cs-parser.jay: Use System.CodeDOM now.
