1 2001-09-27 Miguel de Icaza <miguel@ximian.com>
3 * expression.cs (Cast::Resolve): First resolve the child expression.
5 (LValue): Add new method AddressOf to be used by
8 Change the argument of Store to take an EmitContext instead of an
9 ILGenerator, because things like FieldExpr need to be able to call
10 their children expression to generate the instance code.
12 (Expression::Error, Expression::Warning): Sugar functions for
15 (Expression::MemberLookup): Accept a TypeContainer instead of a
16 Report as the first argument.
18 (Expression::ResolvePrimary): Killed. I still want to improve
19 this as currently the code is just not right.
21 (Expression::ResolveMemberAccess): Simplify, but it is still
24 (Unary::Resolve): Catch errors in AddressOf operators.
26 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
27 index to a byte for the short-version, or the compiler will choose
28 the wrong Emit call, which generates the wrong data.
30 (ParameterReference::Emit, ::Store): same.
32 (FieldExpr::AddressOf): Implement.
34 * typemanager.cs: TypeManager: made public variable instead of
37 * driver.cs: document --fatal.

62 the work of all the checking.
63 (ConvertImplicit): Call CanConvert and only then create object if necessary.
64 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
66 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
67 that is the right way.
69 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
70 overloading resolution. Use everywhere instead of cutting and pasting code.
72 (Binary::ResolveOperator): Use MakeUnionSet.
74 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
75 we have to convert to bool types. Not complete yet.

85 implicit constant expression conversions.
87 (Expression::ConvertNumericExplicit): Finished.
89 (Invocation::Emit): If InstanceExpression is null, then it means
90 that we perform a call on this.

94 * expression.cs (Unary::Emit): Remove some dead code.
95 (Probe): Implement Resolve and Emit for `is'.
96 (Expression::ConvertImplicitRequired): Attempt to do constant
97 expression conversions here. Maybe should be moved to
98 ConvertImplicit, but I am not sure.
99 (Expression::ImplicitLongConstantConversionPossible,
100 Expression::ImplicitIntConstantConversionPossible): New functions
101 that tell whether is it possible to apply an implicit constant
102 expression conversion.

123 (Expression::InternalTypeConstructor): Used to invoke constructors
124 on internal types for default promotions.
126 (Unary::Emit): Implement special handling for the pre/post
127 increment/decrement for overloaded operators, as they need to have
128 the same semantics as the other operators.
130 (Binary::ResolveOperator): ditto.
131 (Invocation::ConversionExists): ditto.

151 expressions that can appear in statements, so that we can provide
152 an alternate path to generate expression that do not leave a value
155 (Expression::Emit, and all the derivatives): We no longer return
156 whether a value is left on the stack or not. Every expression
157 after being emitted leaves a single value on the stack.

187 * assign.cs: track location.
188 (Resolve): Use implicit conversions on assignment.
190 * literal.cs: Oops. Not good, Emit of short access values should
191 pass (Bytes) or the wrong argument will be selected.
193 * expression.cs (Unary::Emit): Emit code for -expr.
195 (Unary::ResolveOperator): Handle `Substract' for non-constants
196 (substract from zero from the non-constants).

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

311 * expression.cs: Instead of having FIXMEs in the Resolve
312 functions, throw exceptions so it is obvious that we are facing a
315 * cs-parser.jay (invocation_expression): Pass Location information.
317 * codegen.cs (CodeGen::Save, CodeGen::CodeGen, CodeGen::Basename):
318 Use a basename for those routines because .NET does not like paths

356 (Binary::ResolveOperator): Re-write bits to quietly continue if no overloaded
357 operators are found instead of making noise ;-)
358 (Unary::ResolveOperator): New method to do precisely the same thing which
359 Binary::ResolveOperator does for Binary expressions.
360 (Unary.method, .Arguments): Add.
361 (Unary::OperName): Implement.
362 (Unary::ForceConversion): Copy and Paste !
364 * class.cs (Operator::Define): Fix a small bug for the case when we have
367 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
368 for the inbuilt operators. Only overloading works for now ;-)
370 2001-09-18 Miguel de Icaza <miguel@ximian.com>

386 (FieldExpr::Emit): Implement.
388 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
389 the last instruction contains a return opcode to avoid generating
390 the last `ret' instruction (this generates correct code, and it is
391 nice to pass the peverify output).
393 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
394 initializer for static and instance variables.
395 (Constructor::Emit): Allow initializer to be null in the case of
396 static constructors. Only emit initializer for instance
399 (TypeContainer::FindMembers): Return a null array if there are no
402 Also fix the code for the MemberTypes.Method branch, as it was not
403 scanning that for operators (or tried to access null variables before).

449 * expression.cs (Expression::OverloadResolve): Drop TypeContainer
452 (Expression::MemberLookup): Provide a version that allows to
453 specify the MemberTypes and BindingFlags.
455 * statement.cs (Block::GetVariableInfo): Forgot to recurse here,

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

558 * modifiers.cs: Do not use `parent', instead use the real type
559 container to evaluate permission settings.

571 * driver.cs: Added --parse option that only parses its input files
574 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
575 incorrect. IsTopLevel is not used to tell whether an object is
576 root_types or not (that can be achieved by testing this ==
577 root_types). But to see if this is a top-level *class* (not
578 necessarly our "toplevel" container).
580 2001-09-14 Ravi Pratap <ravi@ximian.com>
582 * enum.cs (Enum::Define): Modify to call the Lookup method on the
583 parent instead of a direct call to GetType.
585 2001-09-14 Ravi Pratap <ravi@ximian.com>

588 Modifiers.TypeAttr. This should just be a call to that method.

598 * modifiers.cs (FieldAttr): Re-write.

601 (TypeContainer::HaveStaticConstructor): New property to provide access
602 to precisely that info.
604 * modifiers.cs (MethodAttr): Re-write.
605 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
607 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
608 of top-level types as claimed.
610 2001-09-13 Miguel de Icaza <miguel@ximian.com>
612 * expression.cs (MemberLookup): Fruitless attempt to lookup
613 constructors. Maybe I need to emit default constructors? That
614 might be it (currently .NET emits this for me automatically).
615 (Invocation::OverloadResolve): Cope with Arguments == null.
616 (Invocation::EmitArguments): new function, shared by the new
618 (Invocation::Emit): Handle static and instance methods. Emit
619 proper call instruction for virtual or non-virtual invocations.

623 (MethodGroupExpr::InstanceExpression): used conforming to the spec
625 (FieldExpr::Resolve): Set type.

630 SimpleLookup): Auxiliary routines to help parse a qualifier
633 Update qualifier_identifier rule.
635 * codegen.cs: Removed debugging messages.
637 * class.cs: Make this a global thing, this acts just as a "key" to
638 objects that we might have around.
640 (Populate): Only initialize method_builders_to_methods once.
642 * expression.cs (PropertyExpr): Initialize type from the
645 * codegen.cs (EmitContext::EmitBoolExpression): Use propper
646 Resolve pattern. Attempt to implicitly convert value to boolean.
649 * expression.cs: Set the type for the int32/int32 argument case.
650 (Binary::ResolveOperator): Set the return type to boolean for
651 comparission operators
653 * typemanager.cs: Remove debugging print code.
655 (Invocation::Resolve): resolve type.
657 * class.cs: Allocate a MemberInfo of the correct size, as the code
658 elsewhere depends on the test to reflect the correct contents.
660 (Method::) Keep track of parameters, due to System.Reflection holes
662 (TypeContainer::Populate): Keep track of MethodBuilders to Method
665 (TypeContainer::FindMembers): Use ArrayList and then copy an array
666 of the exact size and return that.
668 (Class::LookupMethodByBuilder): New function that maps
669 MethodBuilders to its methods. Required to locate the information
670 on methods because System.Reflection bit us again.
672 * support.cs: New file, contains an interface ParameterData and
673 two implementations: ReflectionParameters and InternalParameters
674 used to access Parameter information. We will need to grow this
677 * expression.cs (Invocation::GetParameterData): implement a cache
678 and a wrapper around the ParameterData creation for methods.
679 (Invocation::OverloadResolve): Use new code.
681 2001-09-13 Ravi Pratap <ravi@ximian.com>

686 (TypeContainer::Populate): Update accordingly.
687 (TypeContainer::FindMembers): Implement.
689 2001-09-13 Miguel de Icaza <miguel@ximian.com>
691 * statement.cs: (VariableInfo::VariableType): New field to be
692 initialized with the full type once it is resolved.
694 2001-09-12 Miguel de Icaza <miguel@ximian.com>

1279 emission to keep a context. Most of the code generation will be

1304 function, and implements a cache that will be useful later when I
1305 do error checking and the semantic analysis on the methods is

1308 and made a method, optional argument tells whether this is a class
1309 or a structure to apply the `has-this' bit.

1330 (Constructor::CallingConvention): Returns the calling convention.
1331 (Constructor::ParameterTypes): Returns the constructor parameter
1334 (TypeContainer::AddConstructor): Keep track of default constructor
1335 and the default static constructor.
1337 (Constructor::) Another class that starts using `public readonly'
1338 instead of properties.
1340 (Constructor::IsDefault): Whether this is a default constructor.
1342 (Field::) use readonly public fields instead of properties also.
1344 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
1345 track of static constructors; If none is used, turn on
1346 BeforeFieldInit in the TypeAttributes.
1348 * cs-parser.jay (opt_argument_list): now the return can be null
1349 for the cases where there are no arguments.
1351 (constructor_declarator): If there is no implicit `base' or
1352 `this', then invoke the default parent constructor.
1354 * modifiers.cs (MethodAttr): New static function maps a set of
1355 modifiers flags into a MethodAttributes enum
1356 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
1357 MethodAttr, TypeAttr to represent the various mappings where the
1359 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
1361 2001-08-19 Miguel de Icaza <miguel@ximian.com>
1363 * parameter.cs (GetParameterInfo): Fix bug where there would be no
1366 * interface.cs (PopulateIndexer): Implemented the code generator
1367 for interface indexers.
1369 2001-08-17 Miguel de Icaza <miguel@ximian.com>
1371 * interface.cs (InterfaceMemberBase): Now we track the new status
1374 (PopulateProperty): Implement property population. Woohoo! Got
1375 Methods and Properties going today.
1377 Removed all the properties for interfaces, and replaced them with
1378 `public readonly' fields.
1380 2001-08-16 Miguel de Icaza <miguel@ximian.com>
1382 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
1383 initialize their hashtables/arraylists only when they are needed
1384 instead of doing this always.
1386 * parameter.cs: Handle refs and out parameters.
1388 * cs-parser.jay: Use an ArrayList to construct the arguments
1389 instead of the ParameterCollection, and then cast that to a
1392 * parameter.cs: Drop the use of ParameterCollection and use
1393 instead arrays of Parameters.
1395 (GetParameterInfo): Use the Type, not the Name when resolving
1398 2001-08-13 Miguel de Icaza <miguel@ximian.com>
1400 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
1401 and instead use public readonly fields.
1403 * class.cs: Put back walking code for type containers.
1405 2001-08-11 Miguel de Icaza <miguel@ximian.com>
1407 * class.cs (MakeConstant): Code to define constants.
1409 * rootcontext.cs (LookupType): New function. Used to locate types
1412 2001-08-08 Miguel de Icaza <miguel@ximian.com>
1414 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
1415 this System.Reflection code is. Kudos to Microsoft
1417 * typemanager.cs: Implement a type cache and avoid loading all
1418 types at boot time. Wrap in LookupType the internals. This made
1419 the compiler so much faster. Wow. I rule!
1421 * driver.cs: Make sure we always load mscorlib first (for
1422 debugging purposes, nothing really important).
1424 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
1425 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
1427 * rootcontext.cs: Lookup types on their namespace; Lookup types
1428 on namespaces that have been imported using the `using' keyword.
1430 * class.cs (TypeContainer::TypeAttr): Virtualize.
1431 (Class::TypeAttr): Return attributes suitable for this bad boy.
1432 (Struct::TypeAttr): ditto.
1433 Handle nested classes.
1434 (TypeContainer::) Remove all the type visiting code, it is now
1435 replaced with the rootcontext.cs code
1437 * rootcontext.cs (GetClassBases): Added support for structs.
1439 2001-08-06 Miguel de Icaza <miguel@ximian.com>
1441 * interface.cs, statement.cs, class.cs, parameter.cs,
1442 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
1443 Drop use of TypeRefs, and use strings instead.
1445 2001-08-04 Miguel de Icaza <miguel@ximian.com>
1449 * class.cs (Struct::Struct): set the SEALED flags after
1450 checking the modifiers.
1451 (TypeContainer::TypeAttr): new property, returns the
1452 TypeAttributes for a class.
1454 * cs-parser.jay (type_list): Oops, list production was creating a
1455 new list of base types.
1457 * rootcontext.cs (StdLib): New property.
1458 (GetInterfaceTypeByName): returns an interface by type name, and
1459 encapsulates error handling here.
1460 (GetInterfaces): simplified.
1461 (ResolveTree): Encapsulated all the tree resolution here.
1462 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
1465 * driver.cs: Add support for --nostdlib, to avoid loading the
1467 (Main): Do not put tree resolution here.
1469 * rootcontext.cs: Beginning of the class resolution.
1471 2001-08-03 Miguel de Icaza <miguel@ximian.com>
1473 * rootcontext.cs: Provide better error reporting.
1475 * cs-parser.jay (interface_base): set our $$ to be interfaces.
1477 * rootcontext.cs (CreateInterface): Handle the case where there
1478 are no parent interfaces.
1480 (CloseTypes): Routine to flush types at the end.
1481 (CreateInterface): Track types.
1482 (GetInterfaces): Returns an array of Types from the list of
1485 * typemanager.c (AddUserType): Mechanism to track user types (puts
1486 the type on the global type hash, and allows us to close it at the
1489 2001-08-02 Miguel de Icaza <miguel@ximian.com>
1491 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
1492 RecordInterface instead.
1494 * cs-parser.jay: Updated to reflect changes above.
1496 * decl.cs (Definition): Keep track of the TypeBuilder type that
1497 represents this type here. Not sure we will use it in the long
1498 run, but wont hurt for now.
1500 * driver.cs: Smaller changes to accomodate the new code.
1502 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
1505 * rootcontext.cs (CreateInterface): New method, used to create
1506 the System.TypeBuilder type for interfaces.
1507 (ResolveInterfaces): new entry point to resolve the interface
1509 (CodeGen): Property, used to keep track of the code generator.
1511 2001-07-26 Miguel de Icaza <miguel@ximian.com>
1513 * cs-parser.jay: Add a second production for delegate_declaration
1516 (enum_body): Put an opt_comma here instead of putting it on
1517 enum_body or enum_member_declarations so we can handle trailing
1518 commas on enumeration members. Gets rid of a shift/reduce.
1520 (type_list): Need a COMMA in the middle.
1522 (indexer_declaration): Tell tokenizer to recognize get/set
1524 * Remove old targets.
1526 * Re-add the parser target.
1528 2001-07-13 Simon Cozens <simon@simon-cozens.org>
1530 * cs-parser.jay: Add precendence rules for a number of operators
1531 ot reduce the number of shift/reduce conflicts in the grammar.
1533 2001-07-17 Miguel de Icaza <miguel@ximian.com>
1535 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
1538 Get rid of old crufty code.
1540 * rootcontext.cs: Use this to keep track of the parsed
1541 representation and the defined types available to the program.
1543 * gen-treedump.cs: adjust for new convention.
1545 * type.cs: Split out the type manager, and the assembly builder
1548 * typemanager.cs: the type manager will live here now.
1550 * cil-codegen.cs: And the code generator here.
1552 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
1554 * makefile: Fixed up for easy making.
1556 2001-07-13 Simon Cozens <simon@simon-cozens.org>
1558 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
1561 (unary_expression): Expand pre_increment_expression and
1562 post_decrement_expression to reduce a shift/reduce.
1564 2001-07-11 Simon Cozens
1566 * cs-tokenizer.cs: Hex numbers should begin with a 0.
1568 Improve allow_keyword_as_indent name.
1570 2001-06-19 Miguel de Icaza <miguel@ximian.com>
1572 * Adjustments for Beta2.
1574 2001-06-13 Miguel de Icaza <miguel@ximian.com>
1576 * decl.cs: Added `Define' abstract method.
1577 (InTransit): new property, used to catch recursive definitions.
1579 * interface.cs: Implement `Define'.
1581 * modifiers.cs: Map Modifiers.constants to
1582 System.Reflection.TypeAttribute flags.
1584 * class.cs: Keep track of types and user-defined types.
1585 (BuilderInit): New method for creating an assembly
1586 (ResolveType): New function to launch the resolution process, only
1587 used by interfaces for now.
1589 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
1590 that are inserted into the name space.
1592 2001-06-08 Miguel de Icaza <miguel@ximian.com>
1594 * ARGH. I have screwed up my tree so many times due to the use of
1595 rsync rather than using CVS. Going to fix this at once.
1597 * driver.cs: Objetify driver. Load assemblies, use assemblies to
1600 2001-06-07 Miguel de Icaza <miguel@ximian.com>
1602 * Experiment successful: Use System.Type rather that our own
1605 2001-05-25 Miguel de Icaza <miguel@ximian.com>
1607 * cs-parser.jay: Removed nsAliases from here.
1609 Use new namespaces, handle `using XXX;'
1611 * namespace.cs: Reimplemented namespace handling, use a recursive
1612 definition of the class. Now we can keep track of using clauses
1613 and catch invalid using clauses.
1615 2001-05-24 Miguel de Icaza <miguel@ximian.com>
1617 * gen-treedump.cs: Adapted for all the renaming.
1619 * expression.cs (Expression): this class now has a Type property
1620 which returns an expression Type.
1622 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
1623 `Type', as this has a different meaning now in the base
1625 2001-05-22 Miguel de Icaza <miguel@ximian.com>
1627 * interface.cs, class.cs: Removed from all the sources the
1628 references to signature computation, as we can not do method
1629 signature computation during the parsing time, as we are not
1630 trying to solve at that point distinguishing:
1634 void a (NS.Blah x) {}
1637 Which depending on the context might be valid or not, as we do not
1638 know if Blah is the same thing as NS.Blah at that point.
1640 * Redid everything so the code uses TypeRefs now instead of
1641 Types. TypeRefs are just temporary type placeholders, that need
1642 to be resolved. They initially have a pointer to a string and the
1643 current scope in which they are used. This is used later by the
1644 compiler to resolve the reference to an actual Type.
1646 * DeclSpace is no longer a CIR.Type, and neither are
1647 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
1648 are all DeclSpaces, but no Types.
1650 * type.cs (TypeRefManager): This implements the TypeRef manager,
1651 which keeps track of all the types that need to be resolved after
1652 the parsing has finished.
1654 2001-05-13 Miguel de Icaza <miguel@ximian.com>
1656 * ARGH. We are going to have to store `foreach' as a class rather
1657 than resolving it, as we need to verify error 1579 after name
1658 resolution. *OR* we could keep a flag that says `This request to
1659 IEnumerator comes from a foreach statement' which we can then use
1660 to generate the error.
1662 2001-05-10 Miguel de Icaza <miguel@ximian.com>
1664 * class.cs (TypeContainer.AddMethod): we now add methods to the
1665 MethodGroup instead of the method hashtable.
1667 * expression.cs: Add MethodGroup abstraction, which gets us one
1668 step closer to the specification in the way we handle method
1671 * cs-parser.jay (primary_expression): qualified_identifier now
1672 tried to match up an identifier to a local variable reference or
1673 to a parameter reference.
1675 current_local_parameters is now a parser global variable that
1676 points to the current parameters for the block, used during name
1679 (property_declaration): Now creates an implicit `value' argument to
1682 2001-05-09 Miguel de Icaza <miguel@ximian.com>
1684 * parameter.cs: Do not use `param' arguments as part of the
1685 signature, per the spec.
1687 2001-05-08 Miguel de Icaza <miguel@ximian.com>
1689 * decl.cs: Base class for classes, structs and interfaces. This
1690 is the "Declaration Space"
1692 * cs-parser.jay: Use CheckDef for checking declaration errors
1693 instead of having one on each function.
1695 * class.cs: Factor out some code for handling error handling in
1696 accordance to the "Declarations" section in the "Basic Concepts"
1697 chapter in the ECMA C# spec.
1699 * interface.cs: Make all interface member classes derive from
1700 InterfaceMemberBase.
1702 2001-05-07 Miguel de Icaza <miguel@ximian.com>
1704 * Many things: all interfaces are parsed and generated in
1705 gen-treedump. Support for member variables, constructors,
1706 destructors, properties, constants is there.
1708 Beginning of the IL backend, but very little done, just there for
1711 2001-04-29 Miguel de Icaza <miguel@ximian.com>
1713 * cs-parser.jay: Fix labeled statement.
1715 * cs-tokenizer.cs (escape): Escape " and ' always.
1716 ref_line, ref_name: keep track of the line/filename as instructed
1717 by #line by the compiler.
1720 2001-04-27 Miguel de Icaza <miguel@ximian.com>
1722 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
1723 to match the values in System.CodeDOM.
1725 Divid renamed to Divide.
1727 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
1729 (Statements.set): remove.
1731 * System.CodeDOM/CodeCatchClause.cs: always have a valid
1734 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
1735 falseStatements always have valid values.
1737 * cs-parser.jay: Use System.CodeDOM now.
