39 around, I wonder why I need this.
41 foreach_block: Make the new foreach_block the current_block.
43 * parameter.cs (Parameters.GetEmptyReadOnlyParameters): New
44 function used to return a static Parameters structure. Used for

161 -- separatedly from the other unary operators. Cleans up the
162 code, and kills the ExpressionStatement dependency in Unary.

931 Qualify the name of the delegate, not its return type !
933 * expression.cs (ImplicitReferenceConversion): Implement guts of implicit array

944 * cs-parser.jay (delegate_declaration): Store the fully qualified
945 name as it is a type declaration.

1009 methods on value types. We need to pass the address to structure
1010 methods rather than the object itself. (The equivalent code to
1011 emit "this" for structures leaves the entire structure on the
1012 stack instead of a pointer to it).
1014 (ParameterReference::DoResolve): Compute the real index for the
1015 argument based on whether the method takes or not a `this' pointer
1016 (ie, the method is static).
1018 * codegen.cs (EmitContext::GetTemporaryStorage): Used to store

1057 to TypeContainer mapping to see if a type is user-defined.
1059 * class.cs (TypeContainer::CloseType): Implement.
1061 (TypeContainer::DefineDefaultConstructor): Use Basename, not Name while creating
1062 the default constructor.
1064 (TypeContainer::Populate): Fix minor bug which led to creating default constructors
1067 (Constructor::IsDefault): Fix up logic to determine if it is the default constructor
1069 * interface.cs (CloseType): Create the type here.

1086 as a source to convert to any reference type.
1088 * statement.cs (Return): Perform any implicit conversions to
1089 expected return type.
1091 Validate use of return statement.
1093 * codegen.cs (EmitContext): Pass the expected return type here.
1095 * class.cs (Method, Constructor, Property): Pass expected return
1096 type to EmitContext.

1110 * codegen.cs: EmitContext now contains a flag indicating whether
1111 code is being generated in a static method or not.
1113 * cs-parser.jay: DecomposeQI, new function that replaces the old
1114 QualifiedIdentifier. Now we always decompose the assembled
1115 strings from qualified_identifier productions into a group of

1131 * expression.cs (New::DoResolve): Revert changes for array creation, doesn't

1142 2001-10-07 Ravi Pratap <ravi@ximian.com>

1179 * class.cs: Catch static methods having the flags override,
1180 virtual or abstract.
1182 * expression.cs (UserCast): This user cast was not really doing
1183 what it was supposed to do. Which is to be born in fully resolved
1184 state. Parts of the resolution were being performed at Emit time!
1188 2001-10-05 Miguel de Icaza <miguel@ximian.com>
1190 * expression.cs: Implicity convert the result from UserCast.

1215 * expression.cs (Expression::ImplicitUserConversion): Rename to
1216 UserDefinedConversion.

1258 instead of inside a tight loop.
1260 (::RequireMethods): Accept an object as the data to set into the
1261 hashtable so we can report interface vs abstract method mismatch.
1263 2001-10-03 Miguel de Icaza <miguel@ximian.com>
1265 * report.cs: Make all of it static.
1267 * rootcontext.cs: Drop object_type and value_type computations, as
1268 we have those in the TypeManager anyways.
1270 Drop report instance variable too, now it is a global.
1272 * driver.cs: Use try/catch on command line handling.
1274 Add --probe option to debug the error reporting system with a test

1299 Also fix logic to find members in base types.

1320 in order from base classes to child classes, so that we can in
1321 child classes look up in our parent for method names and
1322 attributes (required for handling abstract, virtual, new, override
1323 constructs: we need to instrospect our base class, and if we dont
1324 populate the classes in order, the introspection might be
1325 incorrect. For example, a method could query its parent before
1326 the parent has any methods and would determine that the parent has
1327 no abstract methods (while it could have had them)).
1329 (RootContext::CreateType): Record the order in which we define the

1350 not marked abstract or extern).
1352 * expression.cs (TypeOf::Emit): Implement.

1356 * class.cs (Property::Emit): Generate code for properties.
1358 2001-10-02 Ravi Pratap <ravi@ximian.com>

1397 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
1399 2001-10-01 Miguel de Icaza <miguel@ximian.com>
1401 * expression.cs (Expression::ExprClassFromMemberInfo,
1402 Expression::Literalize): Create literal expressions from
1403 FieldInfos which are literals.

1421 * parameter.cs: Do not dereference potential null value.

1452 * cs-tokenizer.cs: Handle properly hex constants that can not fit
1453 into integers, and find the most appropiate integer for it.

1465 * expression.cs (Binary::CheckShiftArguments): Add missing type
1467 (Binary::ResolveOperator): Add type to the logical and and logical
1468 or, Bitwise And/Or and Exclusive Or code paths, it was missing
1471 (Binary::DoNumericPromotions): In the case where either argument
1472 is ulong (and most signed types combined with ulong cause an
1473 error) perform implicit integer constant conversions as well.
1475 2001-09-28 Miguel de Icaza <miguel@ximian.com>
1477 * expression.cs (UserImplicitCast): Method should always be
1479 (Invocation::BetterConversion): Simplified test for IntLiteral.
1481 (Expression::ImplicitNumericConversion): Split this routine out.
1482 Put the code that performs implicit constant integer conversions
1485 (Expression::Resolve): Become a wrapper around DoResolve so we can
1486 check eclass and type being set after resolve.
1488 (Invocation::Badness): Remove this dead function
1490 (Binary::ResolveOperator): Do not compute the expensive argumnets
1491 unless we have a union for it.
1493 (Probe::Emit): Is needs to do an isinst and then
1494 compare against null.
1496 (::CanConvert): Added Location argument. If the Location argument
1497 is null (Location.Null), then we do not report errors. This is
1498 used by the `probe' mechanism of the Explicit conversion. We do
1499 not want to generate an error for something that the user
1500 explicitly requested to be casted. But the pipeline for an
1501 explicit cast first tests for potential implicit casts.
1503 So for now, if the Location is null, it means `Probe only' to
1504 avoid adding another argument. Might have to revise this
1507 (ClassCast): New class used to type cast objects into arbitrary
1508 classes (used in Explicit Reference Conversions).
1510 Implement `as' as well.
1512 Reverted all the patches from Ravi below: they were broken:
1514 * The use of `level' as a mechanism to stop recursive
1515 invocations is wrong. That was there just to catch the
1516 bug with a strack trace but not as a way of addressing
1519 To fix the problem we have to *understand* what is going
1520 on and the interactions and come up with a plan, not
1521 just get things going.
1523 * The use of the type conversion cache that I proposed
1524 last night had an open topic: How does this work across
1525 protection domains. A user defined conversion might not
1526 be public in the location where we are applying the
1527 conversion, a different conversion might be selected
1528 (ie, private A->B (better) but public B->A (worse),
1529 inside A, A->B applies, but outside it, B->A will
1532 * On top of that (ie, even if the above is solved),
1533 conversions in a cache need to be abstract. Ie, `To
1534 convert from an Int to a Short use an OpcodeCast', not
1535 `To convert from an Int to a Short use the OpcodeCast on
1536 the variable 5' (which is what this patch was doing).
1538 2001-09-28 Ravi Pratap <ravi@ximian.com>
1540 * expression.cs (Invocation::ConversionExists): Re-write to use
1541 the conversion cache
1543 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
1544 cache all conversions done, not just user-defined ones.
1546 (Invocation::BetterConversion): The real culprit. Use ConversionExists
1547 to determine if a conversion exists instead of acutually trying to
1548 perform the conversion. It's faster too.
1550 (Expression::ConvertExplicit): Modify to use ConversionExists to check
1551 and only then attempt the implicit conversion.
1553 2001-09-28 Ravi Pratap <ravi@ximian.com>
1555 * expression.cs (ConvertImplicit): Use a cache for conversions
1556 already found. Check level of recursion and bail out if necessary.

1560 * typemanager.cs (string_concat_string_string, string_concat_object_object):
1561 Export standard methods that we expect for string operations.
1563 * statement.cs (Block::UsageWarning): Track usage of variables and
1564 report the errors for not used variables.
1566 * expression.cs (Conditional::Resolve, ::Emit): Implement ?:
1569 2001-09-27 Miguel de Icaza <miguel@ximian.com>
1571 * codegen.cs: remove unnneded code
1573 * expression.cs: Removed BuiltinTypeAccess class
1575 Fix the order in which implicit conversions are
1578 The previous fixed dropped support for boxed conversions (adding a
1579 test to the test suite now)
1581 (UserImplicitCast::CanConvert): Remove test for source being null,
1582 that code is broken. We should not feed a null to begin with, if
1583 we do, then we should track the bug where the problem originates
1584 and not try to cover it up here.
1586 Return a resolved expression of type UserImplicitCast on success
1587 rather than true/false. Ravi: this is what I was talking about,
1588 the pattern is to use a static method as a "constructor" for
1591 Also, do not create arguments until the very last minute,
1592 otherwise we always create the arguments even for lookups that
1593 will never be performed.
1595 (UserImplicitCast::Resolve): Eliminate, objects of type
1596 UserImplicitCast are born in a fully resolved state.
1598 * typemanager.cs (InitCoreTypes): Init also value_type
1601 * expression.cs (Cast::Resolve): First resolve the child expression.
1603 (LValue): Add new method AddressOf to be used by
1606 Change the argument of Store to take an EmitContext instead of an
1607 ILGenerator, because things like FieldExpr need to be able to call
1608 their children expression to generate the instance code.
1610 (Expression::Error, Expression::Warning): Sugar functions for
1613 (Expression::MemberLookup): Accept a TypeContainer instead of a
1614 Report as the first argument.
1616 (Expression::ResolvePrimary): Killed. I still want to improve
1617 this as currently the code is just not right.
1619 (Expression::ResolveMemberAccess): Simplify, but it is still
1622 (Unary::Resolve): Catch errors in AddressOf operators.
1624 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
1625 index to a byte for the short-version, or the compiler will choose
1626 the wrong Emit call, which generates the wrong data.
1628 (ParameterReference::Emit, ::Store): same.
1630 (FieldExpr::AddressOf): Implement.
1632 * typemanager.cs: TypeManager: made public variable instead of
1635 * driver.cs: document --fatal.
1637 * report.cs (ErrorMessage, WarningMessage): new names for the old
1638 Error and Warning classes.
1640 * cs-parser.jay (member_access): Turn built-in access to types
1641 into a normal simplename

1646 with q being null, since this was introducing a bug.
1648 * expression.cs (ConvertImplicit): Do built-in conversions first.
1650 2001-09-27 Ravi Pratap <ravi@ximian.com>

1659 * expression.cs (UserImplicitCast::CanConvert): Static method to do
1660 the work of all the checking.
1661 (ConvertImplicit): Call CanConvert and only then create object if necessary.
1662 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
1664 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
1665 that is the right way.
1667 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
1668 overloading resolution. Use everywhere instead of cutting and pasting code.
1670 (Binary::ResolveOperator): Use MakeUnionSet.
1672 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
1673 we have to convert to bool types. Not complete yet.

1679 * expression.cs (Expression::TryImplicitIntConversion): Attempts
1680 to provide an expression that performsn an implicit constant int
1681 conversion (section 6.1.6).
1682 (Expression::ConvertImplicitRequired): Reworked to include
1683 implicit constant expression conversions.
1685 (Expression::ConvertNumericExplicit): Finished.
1687 (Invocation::Emit): If InstanceExpression is null, then it means
1688 that we perform a call on this.
1690 2001-09-26 Miguel de Icaza <miguel@ximian.com>
1692 * expression.cs (Unary::Emit): Remove some dead code.
1693 (Probe): Implement Resolve and Emit for `is'.
1694 (Expression::ConvertImplicitRequired): Attempt to do constant
1695 expression conversions here. Maybe should be moved to
1696 ConvertImplicit, but I am not sure.
1697 (Expression::ImplicitLongConstantConversionPossible,
1698 Expression::ImplicitIntConstantConversionPossible): New functions
1699 that tell whether is it possible to apply an implicit constant
1700 expression conversion.

1705 * cs-parser.jay: Update operator constants.
1707 * parameter.cs (Parameters::GetParameterInfo): Hook up VerifyArgs

1709 (Parameters::VerifyArgs): Verifies that no two arguments have the
1712 * class.cs (Operator): Update the operator names to reflect the
1713 ones that the spec expects (as we are just stringizing the
1716 * expression.cs (Unary::ResolveOperator): Fix bug: Use
1717 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
1718 previous usage did only work for our methods.
1719 (Expression::ConvertImplicit): Handle decimal implicit numeric
1720 conversions as well.
1721 (Expression::InternalTypeConstructor): Used to invoke constructors
1722 on internal types for default promotions.
1724 (Unary::Emit): Implement special handling for the pre/post
1725 increment/decrement for overloaded operators, as they need to have
1726 the same semantics as the other operators.
1728 (Binary::ResolveOperator): ditto.

1730 (UserImplicitCast::Resolve): ditto.

1746 * assign.cs (Assign): Make it inherit from ExpressionStatement.
1748 * expression.cs (ExpressionStatement): New base class used for
1749 expressions that can appear in statements, so that we can provide
1750 an alternate path to generate expression that do not leave a value
1753 (Expression::Emit, and all the derivatives): We no longer return
1754 whether a value is left on the stack or not. Every expression
1755 after being emitted leaves a single value on the stack.

1781 (ConvertImplicit): Do user-defined conversion if it exists.
1783 2001-09-24 Miguel de Icaza <miguel@ximian.com>
1785 * assign.cs: track location.
1786 (Resolve): Use implicit conversions on assignment.

1851 * typemanager.cs: declare and load enum_type, delegate_type and
1854 * expression.cs (Expression::Emit): Now emit returns a value that
1855 tells whether a value is left on the stack or not. This strategy
1856 might be reveted tomorrow with a mechanism that would address
1857 multiple assignments.
1858 (Expression::report118): Utility routine to report mismatches on
1861 (Unary::Report23): Report impossible type/operator combination

1910 functions, throw exceptions so it is obvious that we are facing a
1913 * cs-parser.jay (invocation_expression): Pass Location information.
1915 * codegen.cs (CodeGen::Save, CodeGen::CodeGen, CodeGen::Basename):
1916 Use a basename for those routines because .NET does not like paths

1936 (IntLiteral): export the `Value' of the intliteral.

1986 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
1987 the last instruction contains a return opcode to avoid generating
1988 the last `ret' instruction (this generates correct code, and it is
1989 nice to pass the peverify output).
1991 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
1992 initializer for static and instance variables.
1993 (Constructor::Emit): Allow initializer to be null in the case of

2050 (Expression::MemberLookup): Provide a version that allows to
2051 specify the MemberTypes and BindingFlags.

2056 * modifiers.cs: (Modifiers::TypeAttr): Invert condition on
2057 Beforefieldinit as it was buggy.
2059 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200
2062 * class.cs (Constructor::Emit): Only emit if block is not null.
2063 (TypeContainer::EmitDefaultConstructor): Removed routine, now we
2064 deal with this by semantically definining it as if the user had
2067 (TypeContainer::FindMembers): Removed ad-hoc hack to deal with
2068 constructors as we now "emit" them at a higher level.

2071 default constructors if none was provided.
2073 (ConstructorInitializer): Add methods Resolve and Emit.

2138 * cs-parser.jay (namespace_declaration): Call RecordNamespace to
2141 * rootcontext.cs (IsNamespace): Fixed it :-)
2143 2001-09-14 Miguel de Icaza <miguel@ximian.com>
2145 * class.cs (TypeContainer::FindMembers): Add support for
2147 (MethodCore): New class that encapsulates both the shared aspects
2148 of a Constructor and a Method.

2152 Load System assembly as well as part of the standard library.
2154 * report.cs: Allow throwing exceptions on errors for debugging.
2156 * modifiers.cs: Do not use `parent', instead use the real type
2157 container to evaluate permission settings.
2159 * class.cs: Put Ravi's patch back in. He is right, and we will
2160 have to cope with the
2162 2001-09-14 Ravi Pratap <ravi@ximian.com>
2164 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to

2169 * driver.cs: Added --parse option that only parses its input files
2172 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
2173 incorrect. IsTopLevel is not used to tell whether an object is
2174 root_types or not (that can be achieved by testing this ==
2175 root_types). But to see if this is a top-level *class* (not
2176 necessarly our "toplevel" container).
2178 2001-09-14 Ravi Pratap <ravi@ximian.com>
2180 * enum.cs (Enum::Define): Modify to call the Lookup method on the

2185 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
2186 Modifiers.TypeAttr. This should just be a call to that method.
2188 * modifiers.cs (TypeAttr): Re-write and take an extra argument, the TypeContainer
2189 object so that we can determine if we are top-level or not.
2191 * delegate.cs (Delegate::Define): Update call to TypeAttr method to pass in the

2200 to precisely that info.
2202 * modifiers.cs (MethodAttr): Re-write.
2203 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
2205 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
2206 of top-level types as claimed.
2208 2001-09-13 Miguel de Icaza <miguel@ximian.com>
2210 * expression.cs (MemberLookup): Fruitless attempt to lookup
2211 constructors. Maybe I need to emit default constructors? That
2212 might be it (currently .NET emits this for me automatically).

2214 (Invocation::EmitArguments): new function, shared by the new

2236 objects that we might have around.
2238 (Populate): Only initialize method_builders_to_methods once.
2240 * expression.cs (PropertyExpr): Initialize type from the
2243 * codegen.cs (EmitContext::EmitBoolExpression): Use propper

2247 * expression.cs: Set the type for the int32/int32 argument case.
2248 (Binary::ResolveOperator): Set the return type to boolean for
2249 comparission operators
2251 * typemanager.cs: Remove debugging print code.
2253 (Invocation::Resolve): resolve type.
2255 * class.cs: Allocate a MemberInfo of the correct size, as the code
2256 elsewhere depends on the test to reflect the correct contents.
2258 (Method::) Keep track of parameters, due to System.Reflection holes
2260 (TypeContainer::Populate): Keep track of MethodBuilders to Method
2263 (TypeContainer::FindMembers): Use ArrayList and then copy an array
2264 of the exact size and return that.
2266 (Class::LookupMethodByBuilder): New function that maps
2267 MethodBuilders to its methods. Required to locate the information
2268 on methods because System.Reflection bit us again.
2270 * support.cs: New file, contains an interface ParameterData and
2271 two implementations: ReflectionParameters and InternalParameters
2272 used to access Parameter information. We will need to grow this
2275 * expression.cs (Invocation::GetParameterData): implement a cache
2276 and a wrapper around the ParameterData creation for methods.
2277 (Invocation::OverloadResolve): Use new code.
2279 2001-09-13 Ravi Pratap <ravi@ximian.com>

2333 2001-09-12 Ravi Pratap <ravi@ximian.com>
2335 * class.cs (TypeContainer::FindMembers): Method which does exactly
2336 what Type.FindMembers does, only we don't have to use reflection. No
2339 * typemanager.cs (typecontainers): New hashtable to hold the corresponding
2340 typecontainer objects as we need to get at them.

2369 (Property::Define): Ditto.

2383 addOn_ and removeOn_
2385 * genericparser.cs (GenericParser::error): Overloaded method to handle the case

2588 will is used during the tree rewriting as we resolve them during

2757 (specific_catch_clauses, specific_catch_clause): Ditto.
2758 (opt_general_catch_clause, opt_specific_catch_clauses): Ditto
2759 (catch_args, opt_catch_args): New productions.
2760 (catch_clause): Rewrite to use the new productions above
2761 (catch_clauses): Modify accordingly.
2762 (opt_catch_clauses): New production to use in try_statement
2763 (try_statement): Revamp. Basically, we get rid of one unnecessary rule
2764 and re-write the code in the actions to extract the specific and
2765 general catch clauses by being a little smart ;-)
2767 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
2768 Hooray, try and catch statements parse fine !
2770 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
2772 * statement.cs (Block::GetVariableType): Fix logic to extract the type
2773 string from the hashtable of variables.
2775 * cs-parser.jay (event_accessor_declarations): Trivial fix. Man, how did
2776 I end up making that mistake ;-)
2777 (catch_clauses): Fixed gross error which made Key and Value of the
2778 DictionaryEntry the same : $1 !!
2780 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
2782 * cs-tokenizer.cs (initTokens): Add keywords 'add' and 'remove'
2784 * cs-parser.jay (event_declaration): Correct to remove the semicolon
2785 when the add and remove accessors are specified.
2787 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
2789 * cs-parser.jay (IndexerDeclaration): New helper class to hold
2790 information about indexer_declarator.
2791 (indexer_declarator): Implement actions.
2792 (parsing_indexer): New local boolean used to keep track of whether
2793 we are parsing indexers or properties. This is necessary because
2794 implicit_parameters come into picture even for the get accessor in the
2796 (get_accessor_declaration, set_accessor_declaration): Correspondingly modified.
2798 * class.cs (Indexer): New class for indexer declarations.
2799 (TypeContainer::AddIndexer): New method to add an indexer to a type.
2800 (TypeContainer::indexers): New member to hold list of indexers for the
2803 2001-08-27 Ravi Pratap <ravi@che.iitm.ac.in>
2805 * cs-parser.jay (add_accessor_declaration): Implement action.
2806 (remove_accessor_declaration): Implement action.
2807 (event_accessors_declaration): Implement
2808 (variable_declarators): swap statements for first rule - trivial.
2810 * class.cs (Event): New class to hold information about event
2812 (TypeContainer::AddEvent): New method to add an event to a type
2813 (TypeContainer::events): New member to hold list of events.
2815 * cs-parser.jay (event_declaration): Implement actions.
2817 2001-08-27 Ravi Pratap <ravi@che.iitm.ac.in>
2819 * cs-parser.jay (dim_separators): Implement. Make it a string
2820 concatenating all the commas together, just as they appear.
2821 (opt_dim_separators): Modify accordingly
2822 (rank_specifiers): Update accordingly. Basically do the same
2823 thing - instead, collect the brackets here.
2824 (opt_rank_sepcifiers): Modify accordingly.
2825 (array_type): Modify to actually return the complete type string
2826 instead of ignoring the rank_specifiers.
2827 (expression_list): Implement to collect the expressions
2828 (variable_initializer): Implement. We make it a list of expressions
2829 essentially so that we can handle the array_initializer case neatly too.
2830 (variable_initializer_list): Implement.
2831 (array_initializer): Make it a list of variable_initializers
2832 (opt_array_initializer): Modify accordingly.
2834 * expression.cs (New::NType): Add enumeration to help us
2835 keep track of whether we have an object/delegate creation
2836 or an array creation.
2837 (New:NewType, New::Rank, New::Indices, New::Initializers): New
2838 members to hold data about array creation.
2839 (New:New): Modify to update NewType
2840 (New:New): New Overloaded contructor for the array creation
2843 * cs-parser.jay (array_creation_expression): Implement to call
2844 the overloaded New constructor.
2846 2001-08-26 Ravi Pratap <ravi@che.iitm.ac.in>
2848 * class.cs (TypeContainer::Constructors): Return member
2849 constructors instead of returning null.
2851 2001-08-26 Miguel de Icaza <miguel@ximian.com>
2853 * typemanager.cs (InitCoreTypes): Initialize the various core
2854 types after we have populated the type manager with the user
2855 defined types (this distinction will be important later while
2856 compiling corlib.dll)
2858 * expression.cs, literal.cs, assign.cs, constant.cs: Started work
2859 on Expression Classification. Now all expressions have a method
2860 `Resolve' and a method `Emit'.
2862 * codegen.cs, cs-parser.jay: Fixed the bug that stopped code
2863 generation from working. Also add some temporary debugging
2866 2001-08-24 Miguel de Icaza <miguel@ximian.com>
2868 * codegen.cs: Lots of code generation pieces. This is only the
2869 beginning, will continue tomorrow with more touches of polish. We
2870 handle the fundamentals of if, while, do, for, return. Others are
2871 trickier and I need to start working on invocations soon.
2873 * gen-treedump.cs: Bug fix, use s.Increment here instead of
2876 * codegen.cs (EmitContext): New struct, used during code
2877 emission to keep a context. Most of the code generation will be
2880 * cs-parser.jay: Add embedded blocks to the list of statements of
2881 this block. So code generation proceeds in a top down fashion.
2883 2001-08-23 Miguel de Icaza <miguel@ximian.com>
2885 * statement.cs: Add support for multiple child blocks.
2887 2001-08-22 Miguel de Icaza <miguel@ximian.com>
2889 * codegen.cs (EmitCode): New function, will emit the code for a
2890 Block of code given a TypeContainer and its ILGenerator.
2892 * statement.cs (Block): Standard public readonly optimization.
2893 (Block::Block constructors): Link children.
2894 (Block::Child): Child Linker.
2895 (Block::EmitVariables): Emits IL variable declarations.
2897 * class.cs: Drop support for MethodGroups here, delay until
2899 (Method::): Applied the same simplification that I did before, and
2900 move from Properties to public readonly fields.
2901 (Method::ParameterTypes): Returns the parameter types for the
2902 function, and implements a cache that will be useful later when I
2903 do error checking and the semantic analysis on the methods is
2905 (Constructor::GetCallingConvention): Renamed from CallingConvetion
2906 and made a method, optional argument tells whether this is a class
2907 or a structure to apply the `has-this' bit.
2908 (Method::GetCallingConvention): Implement, returns the calling
2910 (Method::Define): Defines the type, a second pass is performed
2911 later to populate the methods.
2913 (Constructor::ParameterTypes): implement a cache similar to the
2914 one on Method::ParameterTypes, useful later when we do semantic
2917 (TypeContainer::EmitMethod): New method. Emits methods.
2919 * expression.cs: Removed MethodGroup class from here.
2921 * parameter.cs (Parameters::GetCallingConvention): new method.
2923 2001-08-21 Miguel de Icaza <miguel@ximian.com>
2925 * class.cs (TypeContainer::Populate): Drop RootContext from the
2928 (Constructor::CallingConvention): Returns the calling convention.
2929 (Constructor::ParameterTypes): Returns the constructor parameter
2932 (TypeContainer::AddConstructor): Keep track of default constructor
2933 and the default static constructor.
2935 (Constructor::) Another class that starts using `public readonly'
2936 instead of properties.
2938 (Constructor::IsDefault): Whether this is a default constructor.
2940 (Field::) use readonly public fields instead of properties also.
2942 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
2943 track of static constructors; If none is used, turn on
2944 BeforeFieldInit in the TypeAttributes.
2946 * cs-parser.jay (opt_argument_list): now the return can be null
2947 for the cases where there are no arguments.
2949 (constructor_declarator): If there is no implicit `base' or
2950 `this', then invoke the default parent constructor.
2952 * modifiers.cs (MethodAttr): New static function maps a set of
2953 modifiers flags into a MethodAttributes enum
2954 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
2955 MethodAttr, TypeAttr to represent the various mappings where the
2957 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
2959 2001-08-19 Miguel de Icaza <miguel@ximian.com>
2961 * parameter.cs (GetParameterInfo): Fix bug where there would be no
2964 * interface.cs (PopulateIndexer): Implemented the code generator
2965 for interface indexers.
2967 2001-08-17 Miguel de Icaza <miguel@ximian.com>
2969 * interface.cs (InterfaceMemberBase): Now we track the new status
2972 (PopulateProperty): Implement property population. Woohoo! Got
2973 Methods and Properties going today.
2975 Removed all the properties for interfaces, and replaced them with
2976 `public readonly' fields.
2978 2001-08-16 Miguel de Icaza <miguel@ximian.com>
2980 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
2981 initialize their hashtables/arraylists only when they are needed
2982 instead of doing this always.
2984 * parameter.cs: Handle refs and out parameters.
2986 * cs-parser.jay: Use an ArrayList to construct the arguments
2987 instead of the ParameterCollection, and then cast that to a
2990 * parameter.cs: Drop the use of ParameterCollection and use
2991 instead arrays of Parameters.
2993 (GetParameterInfo): Use the Type, not the Name when resolving
2996 2001-08-13 Miguel de Icaza <miguel@ximian.com>
2998 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
2999 and instead use public readonly fields.
3001 * class.cs: Put back walking code for type containers.
3003 2001-08-11 Miguel de Icaza <miguel@ximian.com>
3005 * class.cs (MakeConstant): Code to define constants.
3007 * rootcontext.cs (LookupType): New function. Used to locate types
3010 2001-08-08 Miguel de Icaza <miguel@ximian.com>
3012 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
3013 this System.Reflection code is. Kudos to Microsoft
3015 * typemanager.cs: Implement a type cache and avoid loading all
3016 types at boot time. Wrap in LookupType the internals. This made
3017 the compiler so much faster. Wow. I rule!
3019 * driver.cs: Make sure we always load mscorlib first (for
3020 debugging purposes, nothing really important).
3022 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
3023 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
3025 * rootcontext.cs: Lookup types on their namespace; Lookup types
3026 on namespaces that have been imported using the `using' keyword.
3028 * class.cs (TypeContainer::TypeAttr): Virtualize.
3029 (Class::TypeAttr): Return attributes suitable for this bad boy.
3030 (Struct::TypeAttr): ditto.
3031 Handle nested classes.
3032 (TypeContainer::) Remove all the type visiting code, it is now
3033 replaced with the rootcontext.cs code
3035 * rootcontext.cs (GetClassBases): Added support for structs.
3037 2001-08-06 Miguel de Icaza <miguel@ximian.com>
3039 * interface.cs, statement.cs, class.cs, parameter.cs,
3040 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
3041 Drop use of TypeRefs, and use strings instead.
3043 2001-08-04 Miguel de Icaza <miguel@ximian.com>
3047 * class.cs (Struct::Struct): set the SEALED flags after
3048 checking the modifiers.
3049 (TypeContainer::TypeAttr): new property, returns the
3050 TypeAttributes for a class.
3052 * cs-parser.jay (type_list): Oops, list production was creating a
3053 new list of base types.
3055 * rootcontext.cs (StdLib): New property.
3056 (GetInterfaceTypeByName): returns an interface by type name, and
3057 encapsulates error handling here.
3058 (GetInterfaces): simplified.
3059 (ResolveTree): Encapsulated all the tree resolution here.
3060 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
3063 * driver.cs: Add support for --nostdlib, to avoid loading the
3065 (Main): Do not put tree resolution here.
3067 * rootcontext.cs: Beginning of the class resolution.
3069 2001-08-03 Miguel de Icaza <miguel@ximian.com>
3071 * rootcontext.cs: Provide better error reporting.
3073 * cs-parser.jay (interface_base): set our $$ to be interfaces.
3075 * rootcontext.cs (CreateInterface): Handle the case where there
3076 are no parent interfaces.
3078 (CloseTypes): Routine to flush types at the end.
3079 (CreateInterface): Track types.
3080 (GetInterfaces): Returns an array of Types from the list of
3083 * typemanager.c (AddUserType): Mechanism to track user types (puts
3084 the type on the global type hash, and allows us to close it at the
3087 2001-08-02 Miguel de Icaza <miguel@ximian.com>
3089 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
3090 RecordInterface instead.
3092 * cs-parser.jay: Updated to reflect changes above.
3094 * decl.cs (Definition): Keep track of the TypeBuilder type that
3095 represents this type here. Not sure we will use it in the long
3096 run, but wont hurt for now.
3098 * driver.cs: Smaller changes to accomodate the new code.
3100 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
3103 * rootcontext.cs (CreateInterface): New method, used to create
3104 the System.TypeBuilder type for interfaces.
3105 (ResolveInterfaces): new entry point to resolve the interface
3107 (CodeGen): Property, used to keep track of the code generator.
3109 2001-07-26 Miguel de Icaza <miguel@ximian.com>
3111 * cs-parser.jay: Add a second production for delegate_declaration
3114 (enum_body): Put an opt_comma here instead of putting it on
3115 enum_body or enum_member_declarations so we can handle trailing
3116 commas on enumeration members. Gets rid of a shift/reduce.
3118 (type_list): Need a COMMA in the middle.
3120 (indexer_declaration): Tell tokenizer to recognize get/set
3122 * Remove old targets.
3124 * Re-add the parser target.
3126 2001-07-13 Simon Cozens <simon@simon-cozens.org>
3128 * cs-parser.jay: Add precendence rules for a number of operators
3129 ot reduce the number of shift/reduce conflicts in the grammar.
3131 2001-07-17 Miguel de Icaza <miguel@ximian.com>
3133 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
3136 Get rid of old crufty code.
3138 * rootcontext.cs: Use this to keep track of the parsed
3139 representation and the defined types available to the program.
3141 * gen-treedump.cs: adjust for new convention.
3143 * type.cs: Split out the type manager, and the assembly builder
3146 * typemanager.cs: the type manager will live here now.
3148 * cil-codegen.cs: And the code generator here.
3150 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
3152 * makefile: Fixed up for easy making.
3154 2001-07-13 Simon Cozens <simon@simon-cozens.org>
3156 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
3159 (unary_expression): Expand pre_increment_expression and
3160 post_decrement_expression to reduce a shift/reduce.
3162 2001-07-11 Simon Cozens
3164 * cs-tokenizer.cs: Hex numbers should begin with a 0.
3166 Improve allow_keyword_as_indent name.
3168 2001-06-19 Miguel de Icaza <miguel@ximian.com>
3170 * Adjustments for Beta2.
3172 2001-06-13 Miguel de Icaza <miguel@ximian.com>
3174 * decl.cs: Added `Define' abstract method.
3175 (InTransit): new property, used to catch recursive definitions.
3177 * interface.cs: Implement `Define'.
3179 * modifiers.cs: Map Modifiers.constants to
3180 System.Reflection.TypeAttribute flags.
3182 * class.cs: Keep track of types and user-defined types.
3183 (BuilderInit): New method for creating an assembly
3184 (ResolveType): New function to launch the resolution process, only
3185 used by interfaces for now.
3187 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
3188 that are inserted into the name space.
3190 2001-06-08 Miguel de Icaza <miguel@ximian.com>
3192 * ARGH. I have screwed up my tree so many times due to the use of
3193 rsync rather than using CVS. Going to fix this at once.
3195 * driver.cs: Objetify driver. Load assemblies, use assemblies to
3198 2001-06-07 Miguel de Icaza <miguel@ximian.com>
3200 * Experiment successful: Use System.Type rather that our own
3203 2001-05-25 Miguel de Icaza <miguel@ximian.com>
3205 * cs-parser.jay: Removed nsAliases from here.
3207 Use new namespaces, handle `using XXX;'
3209 * namespace.cs: Reimplemented namespace handling, use a recursive
3210 definition of the class. Now we can keep track of using clauses
3211 and catch invalid using clauses.
3213 2001-05-24 Miguel de Icaza <miguel@ximian.com>
3215 * gen-treedump.cs: Adapted for all the renaming.
3217 * expression.cs (Expression): this class now has a Type property
3218 which returns an expression Type.
3220 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
3221 `Type', as this has a different meaning now in the base
3223 2001-05-22 Miguel de Icaza <miguel@ximian.com>
3225 * interface.cs, class.cs: Removed from all the sources the
3226 references to signature computation, as we can not do method
3227 signature computation during the parsing time, as we are not
3228 trying to solve at that point distinguishing:
3232 void a (NS.Blah x) {}
3235 Which depending on the context might be valid or not, as we do not
3236 know if Blah is the same thing as NS.Blah at that point.
3238 * Redid everything so the code uses TypeRefs now instead of
3239 Types. TypeRefs are just temporary type placeholders, that need
3240 to be resolved. They initially have a pointer to a string and the
3241 current scope in which they are used. This is used later by the
3242 compiler to resolve the reference to an actual Type.
3244 * DeclSpace is no longer a CIR.Type, and neither are
3245 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
3246 are all DeclSpaces, but no Types.
3248 * type.cs (TypeRefManager): This implements the TypeRef manager,
3249 which keeps track of all the types that need to be resolved after
3250 the parsing has finished.
3252 2001-05-13 Miguel de Icaza <miguel@ximian.com>
3254 * ARGH. We are going to have to store `foreach' as a class rather
3255 than resolving it, as we need to verify error 1579 after name
3256 resolution. *OR* we could keep a flag that says `This request to
3257 IEnumerator comes from a foreach statement' which we can then use
3258 to generate the error.
3260 2001-05-10 Miguel de Icaza <miguel@ximian.com>
3262 * class.cs (TypeContainer.AddMethod): we now add methods to the
3263 MethodGroup instead of the method hashtable.
3265 * expression.cs: Add MethodGroup abstraction, which gets us one
3266 step closer to the specification in the way we handle method
3269 * cs-parser.jay (primary_expression): qualified_identifier now
3270 tried to match up an identifier to a local variable reference or
3271 to a parameter reference.
3273 current_local_parameters is now a parser global variable that
3274 points to the current parameters for the block, used during name
3277 (property_declaration): Now creates an implicit `value' argument to
3280 2001-05-09 Miguel de Icaza <miguel@ximian.com>
3282 * parameter.cs: Do not use `param' arguments as part of the
3283 signature, per the spec.
3285 2001-05-08 Miguel de Icaza <miguel@ximian.com>
3287 * decl.cs: Base class for classes, structs and interfaces. This
3288 is the "Declaration Space"
3290 * cs-parser.jay: Use CheckDef for checking declaration errors
3291 instead of having one on each function.
3293 * class.cs: Factor out some code for handling error handling in
3294 accordance to the "Declarations" section in the "Basic Concepts"
3295 chapter in the ECMA C# spec.
3297 * interface.cs: Make all interface member classes derive from
3298 InterfaceMemberBase.
3300 2001-05-07 Miguel de Icaza <miguel@ximian.com>
3302 * Many things: all interfaces are parsed and generated in
3303 gen-treedump. Support for member variables, constructors,
3304 destructors, properties, constants is there.
3306 Beginning of the IL backend, but very little done, just there for
3309 2001-04-29 Miguel de Icaza <miguel@ximian.com>
3311 * cs-parser.jay: Fix labeled statement.
3313 * cs-tokenizer.cs (escape): Escape " and ' always.
3314 ref_line, ref_name: keep track of the line/filename as instructed
3315 by #line by the compiler.
3318 2001-04-27 Miguel de Icaza <miguel@ximian.com>
3320 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
3321 to match the values in System.CodeDOM.
3323 Divid renamed to Divide.
3325 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
3327 (Statements.set): remove.
3329 * System.CodeDOM/CodeCatchClause.cs: always have a valid
3332 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
3333 falseStatements always have valid values.
3335 * cs-parser.jay: Use System.CodeDOM now.
