	* typemanager.cs: declare and load enum_type, delegate_type and
	void_type. 

	* expression.cs (Expression::Emit): Now emit returns a value that

	* codegen.cs (CodeGen::EmitTopBlock): Pass initial sequence

	* expression.cs:  Instead of having FIXMEs in the Resolve
	functions, throw exceptions so it is obvious that we are facing a
	bug. 

	* cs-parser.jay (invocation_expression): Pass Location information.

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

	binding 
	(FieldExpr::Emit): Implement.

	* codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
	the last instruction contains a return opcode to avoid generating
	the last `ret' instruction (this generates correct code, and it is
	nice to pass the peverify output).

	* class.cs (TypeContainer::EmitFieldInitializers): Implement field
	initializer for static and instance variables.
	(Constructor::Emit): Allow initializer to be null in the case of
	static constructors.  Only emit initializer for instance
	constructors. 

	(TypeContainer::FindMembers): Return a null array if there are no
	matches.

	argument.

	constructors as we now "emit" them at a higher level.

	(TypeContainer::DefineDefaultConstructor): Used to define the

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

	* modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to
	FamORAssem, not FamANDAssem.
	
2001-09-14  Miguel de Icaza  <miguel@ximian.com>

	* driver.cs: Added --parse option that only parses its input files
	and terminates.

	* class.cs: Reverted last change from Ravi to IsTopLevel.  That is
	incorrect.  IsTopLevel is not used to tell whether an object is
	root_types or not (that can be achieved by testing this ==
	root_types).  But to see if this is a top-level *class* (not
	necessarly our "toplevel" container). 

2001-09-14  Ravi Pratap  <ravi@ximian.com>

	* enum.cs (Enum::Define): Modify to call the Lookup method on the

	to precisely that info.

	* modifiers.cs (MethodAttr): Re-write.
	(EventAttr): Remove altogether as there seems to be no ostensible use for it.

	* class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
	of top-level types as claimed.
	
2001-09-13  Miguel de Icaza  <miguel@ximian.com>

	* expression.cs (MemberLookup): Fruitless attempt to lookup
	constructors.  Maybe I need to emit default constructors?  That

	(Invocation::OverloadResolve): Cope with Arguments == null.
	(Invocation::EmitArguments): new function, shared by the new
	constructor and us.

	PropertyType. 

	* codegen.cs (EmitContext::EmitBoolExpression): Use propper

	(Binary::ResolveOperator): Set the return type to boolean for
	comparission operators

	* typemanager.cs: Remove debugging print code.

	(Invocation::Resolve): resolve type.

	* class.cs: Allocate a MemberInfo of the correct size, as the code
	elsewhere depends on the test to reflect the correct contents.

	(Method::) Keep track of parameters, due to System.Reflection holes

	(TypeContainer::Populate): Keep track of MethodBuilders to Method
	mapping here.

	(TypeContainer::FindMembers): Use ArrayList and then copy an array
	of the exact size and return that.

	(Class::LookupMethodByBuilder): New function that maps
	MethodBuilders to its methods.  Required to locate the information
	on methods because System.Reflection bit us again.

	* support.cs: New file, contains an interface ParameterData and
	two implementations: ReflectionParameters and InternalParameters
	used to access Parameter information.  We will need to grow this
	as required.

	* expression.cs (Invocation::GetParameterData): implement a cache
	and a wrapper around the ParameterData creation for methods. 
	(Invocation::OverloadResolve): Use new code.

	(OpcodeCast::Emit): fix.

	(ParameterReference::Resolve): Implement.
	(ParameterReference::Emit): Implement.

	* genericparser.cs (GenericParser::error): Overloaded method to handle the case
	of the location being passed in too. Ideally, this should go later since all
	error reporting should be done through the Report object.

	(Populate): Iterate thru the indexers we have and define them too.
	(Indexer.GetMethodBuilder, .SetMethodBuilder): New members to hold the method builders

	readonly fields for all these cases ?

2001-08-31  Ravi Pratap  <ravi@che.iitm.ac.in>

	* class.cs (Property): Revamp to use the convention of making fields readonly.
	Accordingly modify code elsewhere.

	* class.cs : Apply patch from Mr. Mandar <go_mono@hotmail.com> for implementing
	the Define method of the Property class.

	on Expression Classification.  Now all expressions have a method
	`Resolve' and a method `Emit'.

	code. 
	
2001-08-24  Miguel de Icaza  <miguel@ximian.com>

	move from Properties to public readonly fields.
	(Method::ParameterTypes): Returns the parameter types for the
	function, and implements a cache that will be useful later when I
	do error checking and the semantic analysis on the methods is
	performed.

	and made a method, optional argument tells whether this is a class
	or a structure to apply the `has-this' bit.
	(Method::GetCallingConvention): Implement, returns the calling
	convention. 
	(Method::Define): Defines the type, a second pass is performed
	later to populate the methods.

	and the default static constructor.

	(Constructor::) Another class that starts using `public readonly'
	instead of properties. 

	(Constructor::IsDefault): Whether this is a default constructor. 

	(Field::) use readonly public fields instead of properties also.

	(TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
	track of static constructors;  If none is used, turn on
	BeforeFieldInit in the TypeAttributes. 

	* cs-parser.jay (opt_argument_list): now the return can be null
	for the cases where there are no arguments. 

	(constructor_declarator): If there is no implicit `base' or
	`this', then invoke the default parent constructor. 
	
	* modifiers.cs (MethodAttr): New static function maps a set of
	modifiers flags into a MethodAttributes enum
	(FieldAttr): renamed from `Map'.  So now we have FieldAttr,
	MethodAttr, TypeAttr to represent the various mappings where the
	modifiers are used.
	(FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly' 	

2001-08-19  Miguel de Icaza  <miguel@ximian.com>

	* parameter.cs (GetParameterInfo): Fix bug where there would be no
	method arguments.

	* driver.cs: Make sure we always load mscorlib first (for
	debugging purposes, nothing really important).

	* Renamespaced things that were on `CSC' to `CIR'.  Maybe I should
	have moved to `CSC' rather than `CIR'.  Oh man!  The confussion!  

	* rootcontext.cs: Lookup types on their namespace;  Lookup types
	on namespaces that have been imported using the `using' keyword.

	* class.cs (TypeContainer::TypeAttr): Virtualize.
	(Class::TypeAttr): Return attributes suitable for this bad boy.
	(Struct::TypeAttr): ditto.
	Handle nested classes.
	(TypeContainer::) Remove all the type visiting code, it is now
	replaced with the rootcontext.cs code

	* rootcontext.cs (GetClassBases): Added support for structs. 

2001-08-06  Miguel de Icaza  <miguel@ximian.com>

	* interface.cs, statement.cs, class.cs, parameter.cs,
	rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
	Drop use of TypeRefs, and use strings instead.

2001-08-04  Miguel de Icaza  <miguel@ximian.com>

	* rootcontext.cs: 

	* class.cs (Struct::Struct): set the SEALED flags after
	checking the modifiers.

	* tree.cs: Removed RecordType, added RecordClass, RecordStruct and
	RecordInterface instead.

	* cs-parser.jay: Updated to reflect changes above.

	* decl.cs (Definition): Keep track of the TypeBuilder type that
	represents this type here.  Not sure we will use it in the long
	run, but wont hurt for now.

	* driver.cs: Smaller changes to accomodate the new code.

	Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
	when done. 

	* rootcontext.cs (CreateInterface):  New method, used to create
	the System.TypeBuilder type for interfaces.

	rsync rather than using CVS.  Going to fix this at once. 

	* driver.cs: Objetify driver.  Load assemblies, use assemblies to
	load types.

2001-06-07  Miguel de Icaza  <miguel@ximian.com>

	* Experiment successful: Use System.Type rather that our own
	version of Type.  

2001-05-25  Miguel de Icaza  <miguel@ximian.com>

	* cs-parser.jay: Removed nsAliases from here.

	Use new namespaces, handle `using XXX;' 

	* namespace.cs: Reimplemented namespace handling, use a recursive
	definition of the class.  Now we can keep track of using clauses

	* gen-treedump.cs: Adapted for all the renaming.

	* expression.cs (Expression): this class now has a Type property
	which returns an expression Type.

	(Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
	`Type', as this has a different meaning now in the base

2001-05-22  Miguel de Icaza  <miguel@ximian.com>

	* interface.cs, class.cs: Removed from all the sources the
	references to signature computation, as we can not do method
	signature computation during the parsing time, as we are not
	trying to solve at that point distinguishing:

	class X {
		void a (Blah x) {}
		void a (NS.Blah x) {}
	}

	Which depending on the context might be valid or not, as we do not
	know if Blah is the same thing as NS.Blah at that point.

	* Redid everything so the code uses TypeRefs now instead of
	Types.  TypeRefs are just temporary type placeholders, that need
	to be resolved.  They initially have a pointer to a string and the
	current scope in which they are used.  This is used later by the
	compiler to resolve the reference to an actual Type. 

	* DeclSpace is no longer a CIR.Type, and neither are
	TypeContainers (Class and Struct) nor Interfaces nor Enums.  They
	are all DeclSpaces, but no Types. 

	* type.cs (TypeRefManager): This implements the TypeRef manager,
	which keeps track of all the types that need to be resolved after
	the parsing has finished.

	* ARGH.  We are going to have to store `foreach' as a class rather
	than resolving it, as we need to verify error 1579 after name
	resolution.   *OR* we could keep a flag that says `This request to
	IEnumerator comes from a foreach statement' which we can then use
	to generate the error.

	* class.cs (TypeContainer.AddMethod): we now add methods to the
	MethodGroup instead of the method hashtable.  

	* expression.cs: Add MethodGroup abstraction, which gets us one
	step closer to the specification in the way we handle method
	declarations.  

	* cs-parser.jay (primary_expression): qualified_identifier now
	tried to match up an identifier to a local variable reference or
	to a parameter reference.

	current_local_parameters is now a parser global variable that
	points to the current parameters for the block, used during name
	lookup.

	(property_declaration): Now creates an implicit `value' argument to
	the set accessor.

2001-05-09  Miguel de Icaza  <miguel@ximian.com>

	* parameter.cs: Do not use `param' arguments as part of the
	signature, per the spec.

2001-05-08  Miguel de Icaza  <miguel@ximian.com>

	* decl.cs: Base class for classes, structs and interfaces.  This
	is the "Declaration Space" 

	* cs-parser.jay: Use CheckDef for checking declaration errors
	instead of having one on each function.

	* class.cs: Factor out some code for handling error handling in
	accordance to the "Declarations" section in the "Basic Concepts"
	chapter in the ECMA C# spec.

	* interface.cs: Make all interface member classes derive from
	InterfaceMemberBase.

2001-05-07  Miguel de Icaza  <miguel@ximian.com>

	* Many things: all interfaces are parsed and generated in
	gen-treedump.  Support for member variables, constructors,
	destructors, properties, constants is there.

	Beginning of the IL backend, but very little done, just there for
	testing purposes. 

2001-04-29  Miguel de Icaza  <miguel@ximian.com>

	* cs-parser.jay: Fix labeled statement.

	* cs-tokenizer.cs (escape): Escape " and ' always.
	ref_line, ref_name: keep track of the line/filename as instructed
	by #line by the compiler.
	Parse #line.

2001-04-27  Miguel de Icaza  <miguel@ximian.com>

	* System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
	to match the values in System.CodeDOM.

	Divid renamed to Divide.

	* System.CodeDOM/CodeForLoopStatement.cs: Always have valid
	statements. 
	(Statements.set): remove.

	* System.CodeDOM/CodeCatchClause.cs: always have a valid
	statements. 

	* System.CodeDOM/CodeIfStatement.cs: trueStatements and
	falseStatements always have valid values. 

	* cs-parser.jay: Use System.CodeDOM now.
