1 2001-09-27 Miguel de Icaza <miguel@ximian.com>
3 * expression.cs: Fix the order in which implicit conversions are
6 The previous fixed dropped support for boxed conversions (adding a
7 test to the test suite now)
9 (UserImplicitCast::CanConvert): Remove test for source being null,
10 that code is broken. We should not feed a null to begin with, if
11 we do, then we should track the bug where the problem originates
12 and not try to cover it up here.
14 Return a resolved expression of type UserImplicitCast on success
15 rather than true/false. Ravi: this is what I was talking about,
16 the pattern is to use a static method as a "constructor" for
19 Also, do not create arguments until the very last minute,
20 otherwise we always create the arguments even for lookups that
21 will never be performed.
23 (UserImplicitCast::Resolve): Eliminate, objects of type
24 UserImplicitCast are born in a fully resolved state.
26 * typemanager.cs (InitCoreTypes): Init also value_type
29 * expression.cs (Cast::Resolve): First resolve the child expression.
31 (LValue): Add new method AddressOf to be used by
34 Change the argument of Store to take an EmitContext instead of an
35 ILGenerator, because things like FieldExpr need to be able to call
36 their children expression to generate the instance code.
38 (Expression::Error, Expression::Warning): Sugar functions for
41 (Expression::MemberLookup): Accept a TypeContainer instead of a
42 Report as the first argument.
44 (Expression::ResolvePrimary): Killed. I still want to improve
45 this as currently the code is just not right.
47 (Expression::ResolveMemberAccess): Simplify, but it is still
50 (Unary::Resolve): Catch errors in AddressOf operators.
52 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
53 index to a byte for the short-version, or the compiler will choose
54 the wrong Emit call, which generates the wrong data.
56 (ParameterReference::Emit, ::Store): same.
58 (FieldExpr::AddressOf): Implement.
60 * typemanager.cs: TypeManager: made public variable instead of
63 * driver.cs: document --fatal.
65 * report.cs (ErrorMessage, WarningMessage): new names for the old
66 Error and Warning classes.
68 * cs-parser.jay (member_access): Turn built-in access to types
69 into a normal simplename

87 * expression.cs (UserImplicitCast::CanConvert): Static method to do
88 the work of all the checking.
89 (ConvertImplicit): Call CanConvert and only then create object if necessary.
90 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
92 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
93 that is the right way.
95 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
96 overloading resolution. Use everywhere instead of cutting and pasting code.
98 (Binary::ResolveOperator): Use MakeUnionSet.
100 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
101 we have to convert to bool types. Not complete yet.
103 2001-09-27 Miguel de Icaza <miguel@ximian.com>
105 * typemanager.cs (TypeManager::CSharpName): support ushort.
107 * expression.cs (Expression::TryImplicitIntConversion): Attempts
108 to provide an expression that performsn an implicit constant int
109 conversion (section 6.1.6).
110 (Expression::ConvertImplicitRequired): Reworked to include
111 implicit constant expression conversions.
113 (Expression::ConvertNumericExplicit): Finished.
115 (Invocation::Emit): If InstanceExpression is null, then it means
116 that we perform a call on this.
118 2001-09-26 Miguel de Icaza <miguel@ximian.com>
120 * expression.cs (Unary::Emit): Remove some dead code.
121 (Probe): Implement Resolve and Emit for `is'.
122 (Expression::ConvertImplicitRequired): Attempt to do constant
123 expression conversions here. Maybe should be moved to
124 ConvertImplicit, but I am not sure.
125 (Expression::ImplicitLongConstantConversionPossible,
126 Expression::ImplicitIntConstantConversionPossible): New functions
127 that tell whether is it possible to apply an implicit constant
128 expression conversion.

140 * class.cs (Operator): Update the operator names to reflect the
141 ones that the spec expects (as we are just stringizing the
144 * expression.cs (Unary::ResolveOperator): Fix bug: Use
145 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
146 previous usage did only work for our methods.
147 (Expression::ConvertImplicit): Handle decimal implicit numeric
149 (Expression::InternalTypeConstructor): Used to invoke constructors
150 on internal types for default promotions.
152 (Unary::Emit): Implement special handling for the pre/post
153 increment/decrement for overloaded operators, as they need to have
154 the same semantics as the other operators.
156 (Binary::ResolveOperator): ditto.
157 (Invocation::ConversionExists): ditto.
158 (UserImplicitCast::Resolve): ditto.
160 2001-09-26 Ravi Pratap <ravi@ximian.com>

176 * expression.cs (ExpressionStatement): New base class used for
177 expressions that can appear in statements, so that we can provide
178 an alternate path to generate expression that do not leave a value
181 (Expression::Emit, and all the derivatives): We no longer return
182 whether a value is left on the stack or not. Every expression
183 after being emitted leaves a single value on the stack.
185 * codegen.cs (EmitContext::EmitStatementExpression): Use the
186 facilties of ExpressionStatement if possible.
188 * cs-parser.jay: Update statement_expression.

196 * expression.cs (Binary::ResolveOperator): Had forgottten to set
197 the type of the expression to the return type of the method if

213 * assign.cs: track location.
214 (Resolve): Use implicit conversions on assignment.
216 * literal.cs: Oops. Not good, Emit of short access values should
217 pass (Bytes) or the wrong argument will be selected.
219 * expression.cs (Unary::Emit): Emit code for -expr.
221 (Unary::ResolveOperator): Handle `Substract' for non-constants
222 (substract from zero from the non-constants).

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

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

333 otherwise nested blocks end up with the same index.
335 * codegen.cs (CodeGen::EmitTopBlock): Pass initial sequence
337 * expression.cs: Instead of having FIXMEs in the Resolve
338 functions, throw exceptions so it is obvious that we are facing a
341 * cs-parser.jay (invocation_expression): Pass Location information.
343 * codegen.cs (CodeGen::Save, CodeGen::CodeGen, CodeGen::Basename):
344 Use a basename for those routines because .NET does not like paths
347 * class.cs (TypeContainer::AddMethod): Do not call DefineName if the name was
350 2001-09-19 Miguel de Icaza <miguel@ximian.com>
352 * typemanager.cs (TypeManager::CoreLookupType): A function to make sure that we
353 are loading the correct data types (throws an exception if not).

356 * expression.cs (Unary::ResolveOperator): return the child
357 expression for expressions which are just +expr.
358 (Unary::ResolveOperator): Return negative literals for -LITERAL
359 expressions (otherwise they are Unary {Literal}).

371 instead of 'Operator'
373 * expression.cs (Binary::ResolveOperator): Update accordingly.

382 (Binary::ResolveOperator): Re-write bits to quietly continue if no overloaded
383 operators are found instead of making noise ;-)
384 (Unary::ResolveOperator): New method to do precisely the same thing which
385 Binary::ResolveOperator does for Binary expressions.
386 (Unary.method, .Arguments): Add.
387 (Unary::OperName): Implement.
388 (Unary::ForceConversion): Copy and Paste !
390 * class.cs (Operator::Define): Fix a small bug for the case when we have
393 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
394 for the inbuilt operators. Only overloading works for now ;-)
396 2001-09-18 Miguel de Icaza <miguel@ximian.com>
398 * expression.cs (CheckedExpr::Resolve, CheckedExpr::Emit,
399 UnCheckedExpr::Resolve, UnCheckedExpr::Emit): Implement.

412 (FieldExpr::Emit): Implement.
414 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
415 the last instruction contains a return opcode to avoid generating
416 the last `ret' instruction (this generates correct code, and it is
417 nice to pass the peverify output).
419 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
420 initializer for static and instance variables.
421 (Constructor::Emit): Allow initializer to be null in the case of
422 static constructors. Only emit initializer for instance
425 (TypeContainer::FindMembers): Return a null array if there are no
428 Also fix the code for the MemberTypes.Method branch, as it was not
429 scanning that for operators (or tried to access null variables before).
431 * assign.cs (Assign::Emit): Handle instance and static fields.
435 * driver.cs: Stop compilation if there are parse errors.
437 * cs-parser.jay (constructor_declaration): Provide default base

440 initializers if none was specified.
441 Catch the fact that constructors should not have parameters.
443 * class.cs: Do not emit parent class initializers for static
444 constructors, that should be flagged as an error.
446 2001-09-18 Ravi Pratap <ravi@ximian.com>
448 * class.cs (RegisterMethodBuilder): Remove : it's unnecessary.
449 Move back code into TypeContainer::Populate.

473 2001-09-17 Miguel de Icaza <miguel@ximian.com>
475 * expression.cs (Expression::OverloadResolve): Drop TypeContainer
478 (Expression::MemberLookup): Provide a version that allows to
479 specify the MemberTypes and BindingFlags.
481 * statement.cs (Block::GetVariableInfo): Forgot to recurse here,
482 so it was not fetching variable information from outer blocks.

491 (TypeContainer::EmitDefaultConstructor): Removed routine, now we
492 deal with this by semantically definining it as if the user had
495 (TypeContainer::FindMembers): Removed ad-hoc hack to deal with
496 constructors as we now "emit" them at a higher level.
498 (TypeContainer::DefineDefaultConstructor): Used to define the
499 default constructors if none was provided.

516 2001-09-17 Ravi Pratap <ravi@ximian.com>
518 * rootcontext.cs (IsNameSpace): Compare against null.

541 * rootcontext.cs: Fix bug: tree.Namespaces might be null.
543 2001-09-16 Ravi Pratap <ravi@ximian.com>
545 * class.cs (EmitStaticFieldInitializers, EmitFieldInitializers): Make public.

553 * interface.cs (Interface::InterfaceAttr): Re-write to be more correct and complete.
554 (Interface::IsTopLevel): Add. Same as TypeContainer::IsTopLevel.

569 * rootcontext.cs (IsNamespace): Fixed it :-)
571 2001-09-14 Miguel de Icaza <miguel@ximian.com>
573 * class.cs (TypeContainer::FindMembers): Add support for
575 (MethodCore): New class that encapsulates both the shared aspects
576 of a Constructor and a Method.

580 Load System assembly as well as part of the standard library.
582 * report.cs: Allow throwing exceptions on errors for debugging.
584 * modifiers.cs: Do not use `parent', instead use the real type
585 container to evaluate permission settings.
587 * class.cs: Put Ravi's patch back in. He is right, and we will
588 have to cope with the
590 2001-09-14 Ravi Pratap <ravi@ximian.com>
592 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to
593 FamORAssem, not FamANDAssem.
595 2001-09-14 Miguel de Icaza <miguel@ximian.com>
597 * driver.cs: Added --parse option that only parses its input files
600 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
601 incorrect. IsTopLevel is not used to tell whether an object is
602 root_types or not (that can be achieved by testing this ==
603 root_types). But to see if this is a top-level *class* (not
604 necessarly our "toplevel" container).
606 2001-09-14 Ravi Pratap <ravi@ximian.com>
608 * enum.cs (Enum::Define): Modify to call the Lookup method on the
609 parent instead of a direct call to GetType.
611 2001-09-14 Ravi Pratap <ravi@ximian.com>
613 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
614 Modifiers.TypeAttr. This should just be a call to that method.

617 object so that we can determine if we are top-level or not.
619 * delegate.cs (Delegate::Define): Update call to TypeAttr method to pass in the

624 * modifiers.cs (FieldAttr): Re-write.
626 * class.cs (TypeContainer::IsTopLevel): Change accessibility to public.
627 (TypeContainer::HaveStaticConstructor): New property to provide access
628 to precisely that info.
630 * modifiers.cs (MethodAttr): Re-write.
631 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
633 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
634 of top-level types as claimed.
636 2001-09-13 Miguel de Icaza <miguel@ximian.com>
638 * expression.cs (MemberLookup): Fruitless attempt to lookup
639 constructors. Maybe I need to emit default constructors? That
640 might be it (currently .NET emits this for me automatically).
641 (Invocation::OverloadResolve): Cope with Arguments == null.
642 (Invocation::EmitArguments): new function, shared by the new
644 (Invocation::Emit): Handle static and instance methods. Emit
645 proper call instruction for virtual or non-virtual invocations.

647 (New::Resolve): Implement.
648 (MemberAccess:Resolve): Implement.
649 (MethodGroupExpr::InstanceExpression): used conforming to the spec
651 (FieldExpr::Resolve): Set type.
653 * support.cs: Handle empty arguments.
655 * cs-parser.jay (CompositeLookup, QualifierIdentifier,
656 SimpleLookup): Auxiliary routines to help parse a qualifier
659 Update qualifier_identifier rule.
661 * codegen.cs: Removed debugging messages.
663 * class.cs: Make this a global thing, this acts just as a "key" to
664 objects that we might have around.
666 (Populate): Only initialize method_builders_to_methods once.
668 * expression.cs (PropertyExpr): Initialize type from the
671 * codegen.cs (EmitContext::EmitBoolExpression): Use propper
672 Resolve pattern. Attempt to implicitly convert value to boolean.
675 * expression.cs: Set the type for the int32/int32 argument case.
676 (Binary::ResolveOperator): Set the return type to boolean for
677 comparission operators
679 * typemanager.cs: Remove debugging print code.
681 (Invocation::Resolve): resolve type.
683 * class.cs: Allocate a MemberInfo of the correct size, as the code
684 elsewhere depends on the test to reflect the correct contents.
686 (Method::) Keep track of parameters, due to System.Reflection holes
688 (TypeContainer::Populate): Keep track of MethodBuilders to Method
691 (TypeContainer::FindMembers): Use ArrayList and then copy an array
692 of the exact size and return that.
694 (Class::LookupMethodByBuilder): New function that maps
695 MethodBuilders to its methods. Required to locate the information
696 on methods because System.Reflection bit us again.
698 * support.cs: New file, contains an interface ParameterData and

1327 (Method::): Applied the same simplification that I did before, and
1328 move from Properties to public readonly fields.
1329 (Method::ParameterTypes): Returns the parameter types for the
1330 function, and implements a cache that will be useful later when I
1331 do error checking and the semantic analysis on the methods is
1333 (Constructor::GetCallingConvention): Renamed from CallingConvetion
1334 and made a method, optional argument tells whether this is a class
1335 or a structure to apply the `has-this' bit.
1336 (Method::GetCallingConvention): Implement, returns the calling
1338 (Method::Define): Defines the type, a second pass is performed
1339 later to populate the methods.
1341 (Constructor::ParameterTypes): implement a cache similar to the
1342 one on Method::ParameterTypes, useful later when we do semantic
1345 (TypeContainer::EmitMethod): New method. Emits methods.
1347 * expression.cs: Removed MethodGroup class from here.
1349 * parameter.cs (Parameters::GetCallingConvention): new method.

1356 (Constructor::CallingConvention): Returns the calling convention.
1357 (Constructor::ParameterTypes): Returns the constructor parameter
1360 (TypeContainer::AddConstructor): Keep track of default constructor
1361 and the default static constructor.
1363 (Constructor::) Another class that starts using `public readonly'
1364 instead of properties.
1366 (Constructor::IsDefault): Whether this is a default constructor.
1368 (Field::) use readonly public fields instead of properties also.
1370 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
1371 track of static constructors; If none is used, turn on
1372 BeforeFieldInit in the TypeAttributes.
1374 * cs-parser.jay (opt_argument_list): now the return can be null
1375 for the cases where there are no arguments.
1377 (constructor_declarator): If there is no implicit `base' or
1378 `this', then invoke the default parent constructor.
1380 * modifiers.cs (MethodAttr): New static function maps a set of
1381 modifiers flags into a MethodAttributes enum
1382 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
1383 MethodAttr, TypeAttr to represent the various mappings where the
1385 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
1387 2001-08-19 Miguel de Icaza <miguel@ximian.com>
1389 * parameter.cs (GetParameterInfo): Fix bug where there would be no
1392 * interface.cs (PopulateIndexer): Implemented the code generator
1393 for interface indexers.
1395 2001-08-17 Miguel de Icaza <miguel@ximian.com>
1397 * interface.cs (InterfaceMemberBase): Now we track the new status
1400 (PopulateProperty): Implement property population. Woohoo! Got
1401 Methods and Properties going today.
1403 Removed all the properties for interfaces, and replaced them with
1404 `public readonly' fields.
1406 2001-08-16 Miguel de Icaza <miguel@ximian.com>
1408 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
1409 initialize their hashtables/arraylists only when they are needed
1410 instead of doing this always.
1412 * parameter.cs: Handle refs and out parameters.
1414 * cs-parser.jay: Use an ArrayList to construct the arguments
1415 instead of the ParameterCollection, and then cast that to a
1418 * parameter.cs: Drop the use of ParameterCollection and use
1419 instead arrays of Parameters.
1421 (GetParameterInfo): Use the Type, not the Name when resolving
1424 2001-08-13 Miguel de Icaza <miguel@ximian.com>
1426 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
1427 and instead use public readonly fields.
1429 * class.cs: Put back walking code for type containers.
1431 2001-08-11 Miguel de Icaza <miguel@ximian.com>
1433 * class.cs (MakeConstant): Code to define constants.
1435 * rootcontext.cs (LookupType): New function. Used to locate types
1438 2001-08-08 Miguel de Icaza <miguel@ximian.com>
1440 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
1441 this System.Reflection code is. Kudos to Microsoft
1443 * typemanager.cs: Implement a type cache and avoid loading all
1444 types at boot time. Wrap in LookupType the internals. This made
1445 the compiler so much faster. Wow. I rule!
1447 * driver.cs: Make sure we always load mscorlib first (for
1448 debugging purposes, nothing really important).
1450 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
1451 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
1453 * rootcontext.cs: Lookup types on their namespace; Lookup types
1454 on namespaces that have been imported using the `using' keyword.
1456 * class.cs (TypeContainer::TypeAttr): Virtualize.
1457 (Class::TypeAttr): Return attributes suitable for this bad boy.
1458 (Struct::TypeAttr): ditto.
1459 Handle nested classes.
1460 (TypeContainer::) Remove all the type visiting code, it is now
1461 replaced with the rootcontext.cs code
1463 * rootcontext.cs (GetClassBases): Added support for structs.
1465 2001-08-06 Miguel de Icaza <miguel@ximian.com>
1467 * interface.cs, statement.cs, class.cs, parameter.cs,
1468 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
1469 Drop use of TypeRefs, and use strings instead.
1471 2001-08-04 Miguel de Icaza <miguel@ximian.com>
1475 * class.cs (Struct::Struct): set the SEALED flags after
1476 checking the modifiers.
1477 (TypeContainer::TypeAttr): new property, returns the
1478 TypeAttributes for a class.
1480 * cs-parser.jay (type_list): Oops, list production was creating a
1481 new list of base types.
1483 * rootcontext.cs (StdLib): New property.
1484 (GetInterfaceTypeByName): returns an interface by type name, and
1485 encapsulates error handling here.
1486 (GetInterfaces): simplified.
1487 (ResolveTree): Encapsulated all the tree resolution here.
1488 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
1491 * driver.cs: Add support for --nostdlib, to avoid loading the
1493 (Main): Do not put tree resolution here.
1495 * rootcontext.cs: Beginning of the class resolution.
1497 2001-08-03 Miguel de Icaza <miguel@ximian.com>
1499 * rootcontext.cs: Provide better error reporting.
1501 * cs-parser.jay (interface_base): set our $$ to be interfaces.
1503 * rootcontext.cs (CreateInterface): Handle the case where there
1504 are no parent interfaces.
1506 (CloseTypes): Routine to flush types at the end.
1507 (CreateInterface): Track types.
1508 (GetInterfaces): Returns an array of Types from the list of
1511 * typemanager.c (AddUserType): Mechanism to track user types (puts
1512 the type on the global type hash, and allows us to close it at the
1515 2001-08-02 Miguel de Icaza <miguel@ximian.com>
1517 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
1518 RecordInterface instead.
1520 * cs-parser.jay: Updated to reflect changes above.
1522 * decl.cs (Definition): Keep track of the TypeBuilder type that
1523 represents this type here. Not sure we will use it in the long
1524 run, but wont hurt for now.
1526 * driver.cs: Smaller changes to accomodate the new code.
1528 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
1531 * rootcontext.cs (CreateInterface): New method, used to create
1532 the System.TypeBuilder type for interfaces.
1533 (ResolveInterfaces): new entry point to resolve the interface
1535 (CodeGen): Property, used to keep track of the code generator.
1537 2001-07-26 Miguel de Icaza <miguel@ximian.com>
1539 * cs-parser.jay: Add a second production for delegate_declaration
1542 (enum_body): Put an opt_comma here instead of putting it on
1543 enum_body or enum_member_declarations so we can handle trailing
1544 commas on enumeration members. Gets rid of a shift/reduce.
1546 (type_list): Need a COMMA in the middle.
1548 (indexer_declaration): Tell tokenizer to recognize get/set
1550 * Remove old targets.
1552 * Re-add the parser target.
1554 2001-07-13 Simon Cozens <simon@simon-cozens.org>
1556 * cs-parser.jay: Add precendence rules for a number of operators
1557 ot reduce the number of shift/reduce conflicts in the grammar.
1559 2001-07-17 Miguel de Icaza <miguel@ximian.com>
1561 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
1564 Get rid of old crufty code.
1566 * rootcontext.cs: Use this to keep track of the parsed
1567 representation and the defined types available to the program.
1569 * gen-treedump.cs: adjust for new convention.
1571 * type.cs: Split out the type manager, and the assembly builder
1574 * typemanager.cs: the type manager will live here now.
1576 * cil-codegen.cs: And the code generator here.
1578 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
1580 * makefile: Fixed up for easy making.
1582 2001-07-13 Simon Cozens <simon@simon-cozens.org>
1584 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
1587 (unary_expression): Expand pre_increment_expression and
1588 post_decrement_expression to reduce a shift/reduce.
1590 2001-07-11 Simon Cozens
1592 * cs-tokenizer.cs: Hex numbers should begin with a 0.
1594 Improve allow_keyword_as_indent name.
1596 2001-06-19 Miguel de Icaza <miguel@ximian.com>
1598 * Adjustments for Beta2.
1600 2001-06-13 Miguel de Icaza <miguel@ximian.com>
1602 * decl.cs: Added `Define' abstract method.
1603 (InTransit): new property, used to catch recursive definitions.
1605 * interface.cs: Implement `Define'.
1607 * modifiers.cs: Map Modifiers.constants to
1608 System.Reflection.TypeAttribute flags.
1610 * class.cs: Keep track of types and user-defined types.
1611 (BuilderInit): New method for creating an assembly
1612 (ResolveType): New function to launch the resolution process, only
1613 used by interfaces for now.
1615 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
1616 that are inserted into the name space.
1618 2001-06-08 Miguel de Icaza <miguel@ximian.com>
1620 * ARGH. I have screwed up my tree so many times due to the use of
1621 rsync rather than using CVS. Going to fix this at once.
1623 * driver.cs: Objetify driver. Load assemblies, use assemblies to
1626 2001-06-07 Miguel de Icaza <miguel@ximian.com>
1628 * Experiment successful: Use System.Type rather that our own
1631 2001-05-25 Miguel de Icaza <miguel@ximian.com>
1633 * cs-parser.jay: Removed nsAliases from here.
1635 Use new namespaces, handle `using XXX;'
1637 * namespace.cs: Reimplemented namespace handling, use a recursive
1638 definition of the class. Now we can keep track of using clauses
1639 and catch invalid using clauses.
1641 2001-05-24 Miguel de Icaza <miguel@ximian.com>
1643 * gen-treedump.cs: Adapted for all the renaming.
1645 * expression.cs (Expression): this class now has a Type property
1646 which returns an expression Type.
1648 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
1649 `Type', as this has a different meaning now in the base
1651 2001-05-22 Miguel de Icaza <miguel@ximian.com>
1653 * interface.cs, class.cs: Removed from all the sources the
1654 references to signature computation, as we can not do method
1655 signature computation during the parsing time, as we are not
1656 trying to solve at that point distinguishing:
1660 void a (NS.Blah x) {}
1663 Which depending on the context might be valid or not, as we do not
1664 know if Blah is the same thing as NS.Blah at that point.
1666 * Redid everything so the code uses TypeRefs now instead of
1667 Types. TypeRefs are just temporary type placeholders, that need
1668 to be resolved. They initially have a pointer to a string and the
1669 current scope in which they are used. This is used later by the
1670 compiler to resolve the reference to an actual Type.
1672 * DeclSpace is no longer a CIR.Type, and neither are
1673 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
1674 are all DeclSpaces, but no Types.
1676 * type.cs (TypeRefManager): This implements the TypeRef manager,
1677 which keeps track of all the types that need to be resolved after
1678 the parsing has finished.
1680 2001-05-13 Miguel de Icaza <miguel@ximian.com>
1682 * ARGH. We are going to have to store `foreach' as a class rather
1683 than resolving it, as we need to verify error 1579 after name
1684 resolution. *OR* we could keep a flag that says `This request to
1685 IEnumerator comes from a foreach statement' which we can then use
1686 to generate the error.
1688 2001-05-10 Miguel de Icaza <miguel@ximian.com>
1690 * class.cs (TypeContainer.AddMethod): we now add methods to the
1691 MethodGroup instead of the method hashtable.
1693 * expression.cs: Add MethodGroup abstraction, which gets us one
1694 step closer to the specification in the way we handle method
1697 * cs-parser.jay (primary_expression): qualified_identifier now
1698 tried to match up an identifier to a local variable reference or
1699 to a parameter reference.
1701 current_local_parameters is now a parser global variable that
1702 points to the current parameters for the block, used during name
1705 (property_declaration): Now creates an implicit `value' argument to
1708 2001-05-09 Miguel de Icaza <miguel@ximian.com>
1710 * parameter.cs: Do not use `param' arguments as part of the
1711 signature, per the spec.
1713 2001-05-08 Miguel de Icaza <miguel@ximian.com>
1715 * decl.cs: Base class for classes, structs and interfaces. This
1716 is the "Declaration Space"
1718 * cs-parser.jay: Use CheckDef for checking declaration errors
1719 instead of having one on each function.
1721 * class.cs: Factor out some code for handling error handling in
1722 accordance to the "Declarations" section in the "Basic Concepts"
1723 chapter in the ECMA C# spec.
1725 * interface.cs: Make all interface member classes derive from
1726 InterfaceMemberBase.
1728 2001-05-07 Miguel de Icaza <miguel@ximian.com>
1730 * Many things: all interfaces are parsed and generated in
1731 gen-treedump. Support for member variables, constructors,
1732 destructors, properties, constants is there.
1734 Beginning of the IL backend, but very little done, just there for
1737 2001-04-29 Miguel de Icaza <miguel@ximian.com>
1739 * cs-parser.jay: Fix labeled statement.
1741 * cs-tokenizer.cs (escape): Escape " and ' always.
1742 ref_line, ref_name: keep track of the line/filename as instructed
1743 by #line by the compiler.
1746 2001-04-27 Miguel de Icaza <miguel@ximian.com>
1748 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
1749 to match the values in System.CodeDOM.
1751 Divid renamed to Divide.
1753 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
1755 (Statements.set): remove.
1757 * System.CodeDOM/CodeCatchClause.cs: always have a valid
1760 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
1761 falseStatements always have valid values.
1763 * cs-parser.jay: Use System.CodeDOM now.
