+
+2001-10-15 Ravi Pratap <ravi@ximian.com>

+2001-10-12 Ravi Pratap <ravi@ximian.com>
+

+ name as it is a type declaration.
+

+ as TypeContainer::DefineType.
+
+ (Populate): Method in which all the definition of the various methods (Invoke)

+
+ (This::LValueResolve): Implement.
+
+ (This::Store): Remove warning, assigning to `this' in structures
+ is
+
+ (Invocation::Emit): Deal with invocation of
+ methods on value types. We need to pass the address to structure
+ methods rather than the object itself. (The equivalent code to
+ emit "this" for structures leaves the entire structure on the
+ stack instead of a pointer to it).
+
+ (ParameterReference::DoResolve): Compute the real index for the
+ argument based on whether the method takes or not a `this' pointer
+ (ie, the method is static).

+ * codegen.cs (EmitContext::GetTemporaryStorage): Used to store
+ value types returned from functions when we need to invoke a
+ method on the sturcture.

+
+2001-10-11 Ravi Pratap <ravi@ximian.com>
+
+ * class.cs (TypeContainer::DefineType): Method to actually do the business of
+ defining the type in the Modulebuilder or Typebuilder. This is to take
+ care of nested types which need to be defined on the TypeBuilder using
+ DefineNestedMethod.

+ methods in RootContext, only ported to be part of TypeContainer.
+
+ (TypeContainer::GetInterfaceOrClass): Ditto.
+
+ (TypeContainer::LookupInterfaceOrClass, ::MakeFQN): Ditto.
+
+ * interface.cs (Interface::DefineInterface): New method. Does exactly
+ what RootContext.CreateInterface did earlier, only it takes care of nested types
+ too.

+
+ (Interface::GetInterfaceByName): Same here.
+

+ (FindMembers): Check in the Builders to TypeContainer mapping instead of the name
+ to TypeContainer mapping to see if a type is user-defined.
+
+ * class.cs (TypeContainer::CloseType): Implement.

+ (TypeContainer::DefineDefaultConstructor): Use Basename, not Name while creating
+ the default constructor.
+
+ (TypeContainer::Populate): Fix minor bug which led to creating default constructors
+ twice.

+
+ * expression.cs (ImplicitReferenceConversion): handle null as well
+ as a source to convert to any reference type.

+ expected return type.
+
+ Validate use of return statement.
+
+ * codegen.cs (EmitContext): Pass the expected return type here.
+
+ * class.cs (Method, Constructor, Property): Pass expected return
+ type to EmitContext.
+
+2001-10-09 Miguel de Icaza <miguel@ximian.com>
+
+ * expression.cs: Make DoResolve take an EmitContext instead of a
+ TypeContainer.
+
+ Replaced `l' and `location' for `loc', for consistency.
+
+ (Error, Warning): Remove unneeded Tc argument.
+
+ * assign.cs, literal.cs, constant.cs: Update to new calling
+ convention.
+
+ * codegen.cs: EmitContext now contains a flag indicating whether
+ code is being generated in a static method or not.
+
+ * cs-parser.jay: DecomposeQI, new function that replaces the old
+ QualifiedIdentifier. Now we always decompose the assembled
+ strings from qualified_identifier productions into a group of
+ memberaccesses.
+
+2001-10-08 Miguel de Icaza <miguel@ximian.com>
+
+ * rootcontext.cs: Deal with field-less struct types correctly now

+2001-10-07 Miguel de Icaza <miguel@ximian.com>
+
+ * statement.cs: Moved most of the code generation here.
+
+2001-10-09 Ravi Pratap <ravi@ximian.com>
+
+ * expression.cs (New::DoResolve): Revert changes for array creation, doesn't
+ seem very right.
+
+ (ElementAccess): Remove useless bits for now - keep checks as the spec
+ says.
+
+2001-10-08 Ravi Pratap <ravi@ximian.com>
+
+ * expression.cs (ElementAccess::DoResolve): Remove my crap code
+ and start performing checks according to the spec.
+
+2001-10-07 Ravi Pratap <ravi@ximian.com>
+
+ * cs-parser.jay (type_suffix*): Remove - they are redundant. Use
+ rank_specifiers instead.
+
+ (rank_specifiers): Change the order in which the rank specifiers are stored

+
+ * cs-parser.jay: Added support for try/catch/finalize.
+
+ * class.cs: Catch static methods having the flags override,
+ virtual or abstract.
+
+ * expression.cs (UserCast): This user cast was not really doing
+ what it was supposed to do. Which is to be born in fully resolved
+ state. Parts of the resolution were being performed at Emit time!
+
+ Fixed this code.
+
+2001-10-05 Miguel de Icaza <miguel@ximian.com>
+
+ * expression.cs: Implicity convert the result from UserCast.
+
+2001-10-05 Ravi Pratap <ravi@ximian.com>
+
+ * expression.cs (Expression::FindMostEncompassingType): Fix bug which
+ prevented it from working correctly.

+2001-10-05 Miguel de Icaza <miguel@ximian.com>
+
+ * typemanager.cs: Make the LookupTypeContainer function static,
+ and not per-instance.
+
+ * class.cs: Make static FindMembers (the one that takes a Type
+ argument).
+
+ * codegen.cs: Add EmitForeach here.
+
+ * cs-parser.jay: Make foreach a toplevel object instead of the
+ inline expansion, as we need to perform semantic analysis on it.
+
+2001-10-05 Ravi Pratap <ravi@ximian.com>
+
+ * expression.cs (Expression::ImplicitUserConversion): Rename to
+ UserDefinedConversion.

+ virtual and newslot bits.
+
+ * class.cs (TypeContainer::RegisterRequiredImplementations):
+ Record methods we need.
+
+ (TypeContainer::MakeKey): Helper function to make keys for
+ MethodBases, since the Methodbase key is useless.
+
+ (TypeContainer::Populate): Call RegisterRequiredImplementations
+ before defining the methods.
+
+ Create a mapping for method_builders_to_methods ahead of time
+ instead of inside a tight loop.
+
+ (::RequireMethods): Accept an object as the data to set into the
+ hashtable so we can report interface vs abstract method mismatch.
+
+2001-10-03 Miguel de Icaza <miguel@ximian.com>
+
+ * report.cs: Make all of it static.
+
+ * rootcontext.cs: Drop object_type and value_type computations, as
+ we have those in the TypeManager anyways.
+
+ Drop report instance variable too, now it is a global.
+
+ * driver.cs: Use try/catch on command line handling.
+
+ Add --probe option to debug the error reporting system with a test
+ suite.
+
+ * report.cs: Add support for exiting program when a probe
+ condition is reached.
+
+2001-10-03 Ravi Pratap <ravi@ximian.com>
+
+ * expression.cs (Binary::DoNumericPromotions): Fix the case when
+ we do a forcible conversion regardless of type, to check if
+ ForceConversion returns a null.
+
+ (Binary::error19): Use location to report error.
+
+ (Unary::error23): Use location here too.
+
+ * ../errors/cs0019.cs : Check in.

+
+ * expression.cs (Expression.MemberLookup): Return null for a rather esoteric
+ case of a non-null MethodInfo object with a length of 0 !
+
+ (Binary::ResolveOperator): Flag error if overload resolution fails to find
+ an applicable member - according to the spec :-)
+ Also fix logic to find members in base types.
+
+ (Unary::ResolveOperator): Same here.
+
+ (Unary::report23): Change name to error23 and make first argument a TypeContainer
+ as I was getting thoroughly confused between this and error19 :-)
+
+ * expression.cs (Expression::ImplicitUserConversion): Re-write fully
+ (::FindMostEncompassedType): Implement.
+ (::FindMostEncompassingType): Implement.
+ (::StandardConversionExists): Implement.

+ mathematical union with no duplicates.
+
+2001-10-03 Miguel de Icaza <miguel@ximian.com>
+
+ * rootcontext.cs (RootContext::PopulateTypes): Populate containers
+ in order from base classes to child classes, so that we can in
+ child classes look up in our parent for method names and
+ attributes (required for handling abstract, virtual, new, override
+ constructs: we need to instrospect our base class, and if we dont
+ populate the classes in order, the introspection might be
+ incorrect. For example, a method could query its parent before
+ the parent has any methods and would determine that the parent has
+ no abstract methods (while it could have had them)).
+
+ (RootContext::CreateType): Record the order in which we define the
+ classes.
+
+2001-10-02 Miguel de Icaza <miguel@ximian.com>

+
+ * rootcontext.cs (RootContext::CreateType): Register all the
+ abstract methods required for the class to be complete and the
+ interface methods that must be implemented.
+
+ * cs-parser.jay: Report error 501 (method requires body if it is

+ * expression.cs (TypeOf::Emit): Implement.

+ * class.cs (Property::Emit): Generate code for properties.
+
+2001-10-02 Ravi Pratap <ravi@ximian.com>
+
+ * expression.cs (Unary::ResolveOperator): Find operators on base type
+ too - we now conform exactly to the spec.
+
+ (Binary::ResolveOperator): Same here.
+
+ * class.cs (Operator::Define): Fix minor quirk in the tests.
+
+ * ../errors/cs0215.cs : Added.
+
+ * ../errors/cs0556.cs : Added.
+
+ * ../errors/cs0555.cs : Added.
+
2001-10-01 Miguel de Icaza <miguel@ximian.com>
