+
+ * cs-parser.jay: Add opt_semicolon to the interface declaration.
+
+ * expression.cs: Pass location information to
+ ConvertImplicitStandard.
+
+ * class.cs: Added debugging code to track return values from
+ interfaces.
+
+2002-03-05 Miguel de Icaza <miguel@ximian.com>
+
+ * expression.cs (Is.DoResolve): If either side of the `is' is an
+ interface, do not flag the warning.
+
+ * ecore.cs (ImplicitReferenceConversion): We need a separate test
+ for interfaces
+
+ * report.cs: Allow for --fatal to be used with --probe.
+
+ * typemanager.cs (NoTypes): Move the definition for the empty Type
+ array here.
+
+ * class.cs (TypeContainer.FindMembers): Also look for methods defined by
+ properties.
+ (TypeContainer.DefineProxy): New function used to proxy to parent
+ implementations when implementing interfaces.
+ (TypeContainer.ParentImplements): used to lookup if our parent
+ implements a public function that is required by an interface.
+ (TypeContainer.VerifyPendingMethods): Hook this up.
+
+ * typemanager.cs (TypeManager, AddModule, AddAssembly): Make the
+ `modules' and `assemblies' arraylists into arrays. We only grow
+ these are the very early start up of the program, so this improves
+ the speedof LookupType (nicely measured).
+
+ * expression.cs (MakeByteBlob): Replaced unsafe code with
+ BitConverter, as suggested by Paolo.
+
+ * cfold.cs (ConstantFold.Binary): Special case: perform constant
+ folding of string concatenation, but if either side is a string,
+ and the other is not, then return null, and let the runtime use
+ the concatenation on the string plus the object (using
+ `Object.ToString').
+
+2002-03-04 Miguel de Icaza <miguel@ximian.com>
+
+ Constant Folding has been implemented now.
+
+ * expression.cs (Unary.Reduce): Do not throw an exception, catch
+ the error instead on types that are not supported in one's
+ complement.
+
+ * constant.cs (Constant and all children): New set of functions to
+ perform implict and explicit conversions.
+
+ * ecore.cs (EnumConstant): Implement the new functions to perform
+ conversion by proxying to the child expression.
+
+ * codegen.cs: (ConstantCheckState): Constant evaluation has its
+ own separate setting that can not be turned off from the command
+ line using --unchecked or --checked and is only controlled using
+ the checked/unchecked statements and expressions. This setting is
+ used by the constant folder to flag errors.
+
+ * expression.cs (CheckedExpr, UncheckedExpr): Set the
+ ConstantCheckState as well.
+
+ During Resolve, they also have to flag the state, because the
+ constant folder runs completely in the Resolve phase.
+
+ * statement.cs (Checked, Unchecked): Set the ConstantCheckState as
+ well.
+
+2002-03-01 Miguel de Icaza <miguel@ximian.com>
+
+ * cfold.cs: New file, this file contains the constant folder.
+
+ * ecore.cs (IMemoryLocation.AddressOf): Now takes an extra
+ argument to track whether we are using the resulting address to
+ load or store a value and provide better error messages.
+
+ (FieldExpr.Emit, FieldExpr.EmitAssign, FieldExpr.AddressOf): Use
+ new AddressOf arguments.
+
+ * statement.cs (Foreach.EmitCollectionForeach): Update
+
+ * expression.cs (Argument.Emit): Call AddressOf with proper
+ arguments to track usage.

+2002-03-01 Ravi Pratap <ravi@ximian.com>
+
+ * cs-parser.jay (member_access): Change the case for pre-defined types
+ to use a MemberAccess instead of a SimpleName. Thanks to Felix again for
+ this suggestion.
+
+ * class.cs (Operator::Emit): If we are abstract or extern, we don't have
+ a method body.
+
+ * attribute.cs (CheckAttribute, ApplyAttribute): Ensure that we treat operators
+ essentially like methods and apply attributes like MethodImplOptions to them too.
+
+ * ecore.cs (SimpleName.SimpleNameResolve): Perform a check on ec.TypeContainer.TypeBuilder
+ not being null.
+
+ * codegen.cs (EmitContext): The constructor now takes in an extra argument specifying the
+ DeclSpace as the distinction is important. We provide sane defaults as usually the TypeContainer
+ is the DeclSpace.
+
+ * Update code everywhere accordingly.
+
+ * ecore.cs : Change references to ec.TypeContainer to ec.DeclSpace where appropriate.
+
+ * cs-parser.jay (enum_declaration): Set the current namespace of the enum.
+
+2002-02-28 Ravi Pratap <ravi@ximian.com>
+
+ * rootcontext.cs (LookupType): As we cycle through the chain of namespaces
+ try performing lookups against those instead of jumping straight into using
+ the 'using' clauses.
+
+ (ImplicitParent): Add. Thanks to Felix Arrese-Igor for this idea.
+
+ (LookupType): Perform lookups in implicit parents too.
+
+ * class.cs (GetInterfaceOrClass): Modify to perform the exact same lookup
+ sequence as RootContext.LookupType.
+
+ * rootcontext.cs (NamespaceLookup): Split out code from LookupType which tries
+ the various cases of namespace lookups into this method.

+
+ * driver.cs: Return 1 or 0 as the program exit code.
+
+2002-02-26 Miguel de Icaza <miguel@ximian.com>
+
+ * expression.cs: Special case the `null' object when trying to
+ auto-compute the type, as anything can be explicitly converted to
+ that.
+
+ * ecore.cs (Expression.ConvertExplicit): Bug fix, thanks for
+ spotting this Paolo.
+
+ (Expression.ImplicitNumericConversion): Perform comparissions of
+ the type using the underlying type in the case of an enumeration
+ rather than using the enumeration type for the compare.
+
+ Cope with the underlying == type case, which is not possible to
+ catch before.
+
+ (Expression.ConvertNumericExplicit): Perform comparissions of
+ the type using the underlying type in the case of an enumeration
+ rather than using the enumeration type for the compare.

+ argument.
+ (If, While, Do): Track location.
+
+ * expression.cs (Binary.ResolveOperator): In the object + string
+ case, I was missing a call to ConvertImplicit
+
+2002-02-25 Ravi Pratap <ravi@ximian.com>
+
+ * parameter.cs (Parameter.ExternalType): Take in extra DeclSpace and
+ Location arguments. Ensure we use RootContext.LookupType to do our work
+ and not try to do a direct Type.GetType and ModuleBuilder.GetType
+
+ * interface.cs (PopulateMethod): Handle the type of the parameter being
+ null gracefully.
+
+ * expression.cs (Invocation.BetterFunction): Handle the case when we
+ have a params method with no fixed arguments and a call is made with no

+
+2002-02-22 Miguel de Icaza <miguel@ximian.com>
+
+ * driver.cs (MainDriver): Be conservative on our command line
+ handling.
+
+ Catch DirectoryNotFoundException when calling GetFiles.

+
+2002-02-21 Miguel de Icaza <miguel@ximian.com>
+
+ * statement.cs (Fixed): Implement the last case of the Fixed
+ statement (string handling).

+ a string; Used by the Fixed statement.
+
+ * typemanager.cs: Add char_ptr_type. Add get_OffsetToStringData method.
+
+ * expression.cs (Binary.ResolveOperator): Remove redundant
+ MemberLookup pn parent type.
+ Optimize union call, we do not need a union if the types are the same.
+ (Unary.ResolveOperator): REmove redundant MemberLookup on parent

+
+ * statement.cs (Fixed): Implement fixed statement for arrays, we
+ are missing one more case before we are done.
+

+ treated as variables, and to have values assigned to them.
+
+ * ecore.cs (Expression.StoreFromPtr): New utility function to
+ store values dereferencing.
+
+2002-02-20 Ravi Pratap <ravi@ximian.com>

+ bug.
+
+ * decl.cs (CheckMethodAgainstBase): Do not allow overriding if
+ the parent implementation is sealed.
+
+ * ../errors/cs0239.cs : Add.
+
+ * attribute.cs (ApplyAttributes): Handle Modulebuilders too.
+
+ * typemanager.cs (unverifiable_code_type): Corresponds to

+
+2002-02-19 Miguel de Icaza <miguel@ximian.com>

+2002-02-14 Miguel de Icaza <miguel@ximian.com>
+
+ * class.cs (Property.Define, Method.Define): Remove newslot when
+ `implementing'.
+
+ * modifiers.cs: My use of NewSlot when `Abstract' was set was
+ wrong. NewSlot should only be used if the `new' keyword is present.
+

+ locating our system dir. Sorry about this.
+
+2002-02-13 Miguel de Icaza <miguel@ximian.com>
+
+ * driver.cs (GetSystemDir): Compute correctly the location of our

+
+ (IsParamsMethodApplicable): Fix bug where we were not checking that the fixed
+ parameters of the parms method are themselves compatible or not !
+
+ (StandardConversionExists): Fix very dangerous bug where we were forgetting
+ to check that a class implements an interface before saying that an implicit
+ conversion was allowed. Use ImplementsInterface to do the checking.
+
+2002-02-13 Miguel de Icaza <miguel@ximian.com>
+
+ * class.cs (Method.Define): Track whether we are an explicit
+ implementation or not. And only call DefineMethodOverride if we
+ are an explicit implementation.
+
+ (Property.DefineMethod): Ditto.
+
+2002-02-11 Ravi Pratap <ravi@ximian.com>
+
+ * expression.cs (BetterFunction): Catch hideous bug which was
+ preventing us from detecting ambiguous calls due to implicit casts i.e
+ cs0121.
+
+2002-01-29 Miguel de Icaza <miguel@ximian.com>
+
+ * support.cs (Pair): Remove un-needed method. I figured why I was
+ getting the error in cs-parser.jay, the variable in a foreach loop
+ is readonly, and the compiler does not really treat this as a variable.
+
+ * cs-parser.jay (fixed_statement): Fix grammar. Use ASSIGN
+ instead of EQUALS in grammar.
+
+ * typemanager.cs (VerifyUnmanaged): Report correct error (208)
+
+ * expression.cs (Unary.DoResolve): Check whether the argument is
+ managed or not.
+
+2002-01-28 Miguel de Icaza <miguel@ximian.com>

+ the variables are public the MS C# compiler refuses to compile
+ code that accesses the field if the variable is part of a foreach
+ statement.
+
+ * statement.cs (Fixed): Begin implementation of the fixed
+ statement.
+
+ (Block.AddVariable): Return the VariableInfo on success and null
+ on failure instead of true/false.
+
+ * cs-parser.jay (foreach): Catch errors on variables already
+ defined (we were ignoring this value before) and properly unwind
+ the block hierarchy
+
+ (fixed_statement): grammar for the fixed statement.

+ propagate infinite loop as `I do return' semantics.

+ to the list of attributes we can add.
+
+ Remove `EmitContext' argument.
+
+ * class.cs (Method.Define): Apply parameter attributes.
+ (Constructor.Define): Apply parameter attributes.
+ (MethodCore.LabelParameters): Move here the core of labeling
+ parameters.
+
+ * support.cs (ReflectionParameters.ParameterModifier,
+ InternalParameters.ParameterModifier): Use IsByRef on the type and
+ only return the OUT bit for these parameters instead of in/out/ref
+ flags.
+
+ This is because I miss-understood things. The ParameterInfo.IsIn
+ and IsOut represent whether the parameter has the [In] and [Out]
+ attributes set.
+
+2002-01-22 Miguel de Icaza <miguel@ximian.com>
+
+ * ecore.cs (FieldExpr.Emit): Release temporaries.

+
+ * ecore.cs (CopyNewMethods): reworked, exposed, made public.
+ Slower, but more generally useful. Used by the abstract

+
+ * expression.cs (ResolveMemberAccess): Reorder the way we evaluate
+ the rules for the special rule on Type/instances. First check if
+ we have the same name, and if so, try that special static path
+ rather than the instance path.
+
+2002-01-18 Miguel de Icaza <miguel@ximian.com>
+
+ * cs-parser.jay: Emit 642 (warning: possible empty statement) for
+ for, while and if.

+
+ * typemanager.cs (IndexerPropetyName): Ravi never tested this
+ piece of code.
+
+ * class.cs (TypeContainer.RegisterRequiredImplementations): Bug

+ * expression.cs (Conditional.DoResolve): Report circular implicit
+ conversions when we neecd to compute it for conditional
+ expressions.

+ (Event, Event.Define): ditto.
+

+
+ * expression.cs (LocalVariableReference.DoResolve): Simplify this

+
+ * driver.cs: Allow negative numbers as an error code to flag.
+
+ * cs-parser.jay: Handle 1551.

+
+ * typemanager.cs (IsPointerType): Utility method which we are going

+
+ (embedded_statement): Modify to include the above.
+
+ * statement.cs (Unsafe): Implement new class for unsafe blocks.
+
+ * codegen.cs (EmitContext.InUnsafe): Add. This determines

+
+ (local_variable_declaration): Update to use local_variable_pointer_type
+ to allow variable declarations of unmanaged pointer types.
+

+ with the case.
+
+2002-01-11 Miguel de Icaza <miguel@ximian.com>
+
+ * ecore.cs (Expression.MemberLookup): instead of taking a
+ parameter `same_type' that was used to tell whether we could
+ access private members we compute our containing type from the
+ EmitContext.
+
+ (FieldExpr): Added partial support for volatile fields. This does
+ not work for volatile fields exposed from assemblies, as I can not
+ figure out how to extract the modreq from it.
+
+ Updated all the source files to use this.
+
+ * codegen.cs (EmitContext): Compute ContainerType ahead of time,
+ because it is referenced by MemberLookup very often.

+
+2002-01-08 Miguel de Icaza <miguel@ximian.com>

+ * class.cs (Indexer.DefineMethod): Incorporate the interface
+ type in the name of the method if we are doing explicit interface
+ implementation.
+
+ * expression.cs (ConversionExists): Remove as it is completely obsolete.
+
+ (BetterConversion): Fix extremely trivial bug where we were referring to
+ ConversionExists instead of StandardConversionExists ! Hooray, things are fine
+ again !
+
+ * ../errors/bug16.cs : Add although we have fixed it.
+
+2002-01-07 Miguel de Icaza <miguel@ximian.com>
+
+ * expression.cs (BaseIndexer): Begin implementation.
+
+ * class.cs (TypeContainer.IsInterfaceMethod): Bug fix.
+
+ * cs-parser.jay (indexer_declarator): Use qualified_identifier
+ production directly to remove a shift/reduce, and implement
+ explicit interface implementation.
+
+ * cs-tokenizer.cs: Fix tokenizer, it was consuming one extra char
+ after a floating point suffix.
+
+ * expression.cs (DoNumericPromotions): Improved the conversion for
+ uint/uint. If we have a constant, we avoid doing a typecast to a
+ larger type.
+
+ * class.cs (Indexer): Implement explicit interface implementation
+ for indexers.
+
+Sat Jan 5 16:08:23 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+ * class.cs: make the default instance constructor public and hidebysig.
+
+2001-01-03 Ravi Pratap <ravi@ximian.com>
+
+ * interface.cs (EmitDefaultMemberAttr): Make this helper method static
+ so we can call it from elsewhere.
+
+ * class.cs (TypeContainer.Emit): Emit the attribute here too. The rule is that
+ we emit it internally if the class has a defined indexer; otherwise the user
+ emits it by decorating the class definition with the DefaultMemberAttribute.
+
+ * attribute.cs (ApplyAttributes): Perform checks to see that the DefaultMember
+ attribute is not used on a type which defines an indexer.
+
+ * cs-tokenizer.cs (get_cmd_arg): Ensure we trim whitespace and also include the tab
+ character when we skip whitespace.
+
+ * ../errors/cs0646.cs : Add.
+
+2002-01-03 Miguel de Icaza <miguel@ximian.com>
+
+ * ecore.cs (SimpleName.ResolveSimpleName): Report error 120
+ again.
+
+ * makefile: Add practical target `mcs3.exe' which builds the third
+ generation compiler.
+
+ * expression.cs (New): Fix structures constructor calling.
+
+ * class.cs (Property, Method, Indexer): Emit Final flag on the
+ method if we are an interface implementation and we are not
+ abstract.
+
+ * ecore.cs (PropertyExpr): New public field `IsBase', tells
+ whether this property is referencing a `base' method.
+
+ * expression.cs (Invocation.EmitCall): take an extra argument:
+ is_base, this is used to determine whether the `call' or
+ `callvirt' opcode should be used.
+
+
+ * delegate.cs: update EmitCall.
+
+ * class.cs (Method.Define): Set NewSlot for the cases where we are
+ not implementing an interface method.
+
+ (Property.Define): ditto.
+
+2002-01-02 Miguel de Icaza <miguel@ximian.com>
+
+ * cs-tokenizer.cs: (Tokenizer.escape): Escape '\r' as '\r' not as
+ 'r'. Allows mcs to parse itself fully.
+
+2002-01-02 Ravi Pratap <ravi@ximian.com>
+
+ * expression.cs (ArrayCreation.num_automatic_initializers): Keep track
+ of the number of initializers that require the InitializeArray method.
+
+ (CheckIndices): Store the Expression in all cases - not the plain value. Also
+ update the above field where necessary.
+
+ (MakeByteBlob): Update accordingly.
+
+ (DoEmit): Call EmitStaticInitializers only if the number of initializers is
+ greater than 2.
+
+ (EmitDynamicInitializers): Update in accordance with the new optimization.
+
+ (ArrayAccess.EmitStoreOpcode): Include char type along with short and ushort - the
+ same OpCode applies.
+
+ * cs-parser.jay : Fix some glaring errors I introduced.
+
+2002-01-01 Ravi Pratap <ravi@ximian.com>
+
+ * parameters.cs (AddVariable, AddConstant): Pass in current_local_parameters
+ so that we can check for name clashes there too.
+
+ * typemanager.cs (default_member_attr_type): The attribute that we need to emit
+ for interface indexers.
+
+ * interfaces.cs (Define): Emit the default member attribute.
+
+ * expression.cs (MakeByteBlob): Fix extremely trivial bug where the wrong
+ variable was being referred to while setting the value ;-)
+
+2002-01-01 Miguel de Icaza <miguel@ximian.com>
+
+ * expression.cs (MakeByteBlob): Optimize: we do not need to fill
+ byte-by-byte information when we know the data is zero.
+
+ Make the block always a multiple of 4, because
+ DefineInitializedData has a bug.
+
+ * assign.cs: Fix, we should assign from the temporary, not from
+ the source.
+
+ * expression.cs (MakeByteBlob): Fix my incorrect code.
+
+2001-12-31 Miguel de Icaza <miguel@ximian.com>
+
+ * typemanager.cs (EnumToUnderlying): This function is used to get
+ the underlying type from an enumeration, because it does not
+ always work.
+
+ * constant.cs: Use the I4_S form for values between -128 and 127.
+
+ * statement.cs (Block.LookupLabel): Looks up a label.
+ (Block): Drop support for labeled blocks.
+
+ (LabeledStatement): New kind of statement that represents a label
+ only.
+
+ (Goto): Finally implement this bad boy.
+
+ * cs-parser.jay: Update to reflect new mechanism to implement
+ labels.
+
+2001-12-30 Miguel de Icaza <miguel@ximian.com>
+
+ * codegen.cs (EmitContext.This): a codegen property that keeps the
+ a single instance of this instead of creating many different this
+ instances.
+
+ * delegate.cs (Delegate.DoResolve): Update to use the property;
+
+ * ecore.cs (SimpleName.SimpleNameResolve): Ditto
+
+ * expression.cs (BaseAccess.DoResolve): Ditto.
+
+2001-12-29 Ravi Pratap <ravi@ximian.com>
+
+ * typemanager.cs (methodimpl_attr_type): Add to hold the type
+ corresponding to System.Runtime.CompilerServices.MethodImplAttribute.
+
+ (InitCoreTypes): Update accordingly.
+
+ * attribute.cs (Resolve): Remember if the attribute is a MethodImplAttribute
+ so we can quickly store the state.
+
+ (ApplyAttributes): Set the correct implementation flags
+ for InternalCall methods.
+
2001-12-29 Miguel de Icaza <miguel@ximian.com>
+ * expression.cs (EmitCall): if a method is not virtual, then do
+ not use callvirt on it.
+
+ (ArrayAccess.EmitAssign): storing non-builtin value types (ie,
+ user defined stuff) requires the use of stobj, which takes an
+ address on the stack instead of an array and an index. So emit
+ the Ldelema operation for it.
+
+ (EmitStoreOpcode): Use stobj for valuetypes.
+
+ (UnaryMutator.EmitCode): Use the right 1 value depending on
+ whether we are dealing with int64/uint64, float or doubles.
+
+ * class.cs (TypeContainer.AddConstructor): Fix the logic to define
+ constructors that I implemented last night.
+
+ (Constructor.IsDefault): Fix to work properly for static
+ constructors.
+
+ * cs-parser.jay (CheckDef): report method signature errors.
+ Update error number 103 to be 132.
+
+ * decl.cs: New AdditionResult enumeration value: MethodExists.
+ Although we do this check for methods later on in the semantic
+ analysis, catching repeated default constructors is so easy that
+ we catch these here.
+
* expression.cs (Binary.DoNumericPromotions): Fix the uint64 type
promotions code.
