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

107 operators are found instead of making noise ;-)
108 (Unary::ResolveOperator): New method to do precisely the same thing which
109 Binary::ResolveOperator does for Binary expressions.
110 (Unary.method, .Arguments): Add.
111 (Unary::OperName): Implement.
112 (Unary::ForceConversion): Copy and Paste !
114 * class.cs (Operator::Define): Fix a small bug for the case when we have
117 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
118 for the inbuilt operators. Only overloading works for now ;-)

136 (FieldExpr::Emit): Implement.
138 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
139 the last instruction contains a return opcode to avoid generating
140 the last `ret' instruction (this generates correct code, and it is
141 nice to pass the peverify output).
143 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
144 initializer for static and instance variables.
145 (Constructor::Emit): Allow initializer to be null in the case of
146 static constructors. Only emit initializer for instance
149 (TypeContainer::FindMembers): Return a null array if there are no
152 Also fix the code for the MemberTypes.Method branch, as it was not
153 scanning that for operators (or tried to access null variables before).

199 * expression.cs (Expression::OverloadResolve): Drop TypeContainer
202 (Expression::MemberLookup): Provide a version that allows to
203 specify the MemberTypes and BindingFlags.

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

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

321 * driver.cs: Added --parse option that only parses its input files
324 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
325 incorrect. IsTopLevel is not used to tell whether an object is
326 root_types or not (that can be achieved by testing this ==
327 root_types). But to see if this is a top-level *class* (not
328 necessarly our "toplevel" container).
330 2001-09-14 Ravi Pratap <ravi@ximian.com>
332 * enum.cs (Enum::Define): Modify to call the Lookup method on the
333 parent instead of a direct call to GetType.
335 2001-09-14 Ravi Pratap <ravi@ximian.com>
337 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
338 Modifiers.TypeAttr. This should just be a call to that method.

351 (TypeContainer::HaveStaticConstructor): New property to provide access
352 to precisely that info.
354 * modifiers.cs (MethodAttr): Re-write.
355 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
357 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
358 of top-level types as claimed.
360 2001-09-13 Miguel de Icaza <miguel@ximian.com>
362 * expression.cs (MemberLookup): Fruitless attempt to lookup
363 constructors. Maybe I need to emit default constructors? That
364 might be it (currently .NET emits this for me automatically).
365 (Invocation::OverloadResolve): Cope with Arguments == null.
366 (Invocation::EmitArguments): new function, shared by the new

380 SimpleLookup): Auxiliary routines to help parse a qualifier
383 Update qualifier_identifier rule.
385 * codegen.cs: Removed debugging messages.

392 * expression.cs (PropertyExpr): Initialize type from the
395 * codegen.cs (EmitContext::EmitBoolExpression): Use propper

400 (Binary::ResolveOperator): Set the return type to boolean for
401 comparission operators
403 * typemanager.cs: Remove debugging print code.
405 (Invocation::Resolve): resolve type.
407 * class.cs: Allocate a MemberInfo of the correct size, as the code
408 elsewhere depends on the test to reflect the correct contents.
410 (Method::) Keep track of parameters, due to System.Reflection holes
412 (TypeContainer::Populate): Keep track of MethodBuilders to Method
415 (TypeContainer::FindMembers): Use ArrayList and then copy an array
416 of the exact size and return that.
418 (Class::LookupMethodByBuilder): New function that maps
419 MethodBuilders to its methods. Required to locate the information
420 on methods because System.Reflection bit us again.
422 * support.cs: New file, contains an interface ParameterData and
423 two implementations: ReflectionParameters and InternalParameters
424 used to access Parameter information. We will need to grow this
427 * expression.cs (Invocation::GetParameterData): implement a cache
428 and a wrapper around the ParameterData creation for methods.
429 (Invocation::OverloadResolve): Use new code.
431 2001-09-13 Ravi Pratap <ravi@ximian.com>

442 initialized with the full type once it is resolved.
444 2001-09-12 Miguel de Icaza <miguel@ximian.com>
446 * parameter.cs (GetParameterInfo): Use a type cache to compute
447 things only once, and to reuse this information

450 (OpcodeCast::Emit): fix.
452 (ParameterReference::Resolve): Implement.
453 (ParameterReference::Emit): Implement.

491 * typemanager.cs (typecontainers): New hashtable to hold the corresponding
492 typecontainer objects as we need to get at them.
493 (TypeManager::AddUserType): Overload to take an extra argument, the TypeContainer.

496 typecontainer object.

499 of just a Report object.

534 * class.cs (Event::Define): Make the prefixes of the accessor methods
537 * genericparser.cs (GenericParser::error): Overloaded method to handle the case
538 of the location being passed in too. Ideally, this should go later since all
539 error reporting should be done through the Report object.
541 * class.cs (TypeContainer.Indexers): New property to access the list of indexers.
542 (Populate): Iterate thru the indexers we have and define them too.

1172 debugging purposes, nothing really important).
1174 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
1175 have moved to `CSC' rather than `CIR'. Oh man! The confussion!

1242 RecordInterface instead.
1244 * cs-parser.jay: Updated to reflect changes above.

1336 (ResolveType): New function to launch the resolution process, only
1337 used by interfaces for now.
1339 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
1340 that are inserted into the name space.
1342 2001-06-08 Miguel de Icaza <miguel@ximian.com>
1344 * ARGH. I have screwed up my tree so many times due to the use of
1345 rsync rather than using CVS. Going to fix this at once.
1347 * driver.cs: Objetify driver. Load assemblies, use assemblies to
1350 2001-06-07 Miguel de Icaza <miguel@ximian.com>
1352 * Experiment successful: Use System.Type rather that our own
1355 2001-05-25 Miguel de Icaza <miguel@ximian.com>
1357 * cs-parser.jay: Removed nsAliases from here.
1359 Use new namespaces, handle `using XXX;'
1361 * namespace.cs: Reimplemented namespace handling, use a recursive
1362 definition of the class. Now we can keep track of using clauses
1363 and catch invalid using clauses.
1365 2001-05-24 Miguel de Icaza <miguel@ximian.com>
1367 * gen-treedump.cs: Adapted for all the renaming.
1369 * expression.cs (Expression): this class now has a Type property
1370 which returns an expression Type.
1372 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
1373 `Type', as this has a different meaning now in the base
1375 2001-05-22 Miguel de Icaza <miguel@ximian.com>
1377 * interface.cs, class.cs: Removed from all the sources the
1378 references to signature computation, as we can not do method
1379 signature computation during the parsing time, as we are not
1380 trying to solve at that point distinguishing:
1384 void a (NS.Blah x) {}
1387 Which depending on the context might be valid or not, as we do not
1388 know if Blah is the same thing as NS.Blah at that point.
1390 * Redid everything so the code uses TypeRefs now instead of
1391 Types. TypeRefs are just temporary type placeholders, that need
1392 to be resolved. They initially have a pointer to a string and the
1393 current scope in which they are used. This is used later by the
1394 compiler to resolve the reference to an actual Type.
1396 * DeclSpace is no longer a CIR.Type, and neither are
1397 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
1398 are all DeclSpaces, but no Types.
1400 * type.cs (TypeRefManager): This implements the TypeRef manager,
1401 which keeps track of all the types that need to be resolved after
1402 the parsing has finished.
1404 2001-05-13 Miguel de Icaza <miguel@ximian.com>
1406 * ARGH. We are going to have to store `foreach' as a class rather
1407 than resolving it, as we need to verify error 1579 after name
1408 resolution. *OR* we could keep a flag that says `This request to
1409 IEnumerator comes from a foreach statement' which we can then use
1410 to generate the error.
1412 2001-05-10 Miguel de Icaza <miguel@ximian.com>
1414 * class.cs (TypeContainer.AddMethod): we now add methods to the
1415 MethodGroup instead of the method hashtable.
1417 * expression.cs: Add MethodGroup abstraction, which gets us one
1418 step closer to the specification in the way we handle method
1421 * cs-parser.jay (primary_expression): qualified_identifier now
1422 tried to match up an identifier to a local variable reference or
1423 to a parameter reference.
1425 current_local_parameters is now a parser global variable that
1426 points to the current parameters for the block, used during name
1429 (property_declaration): Now creates an implicit `value' argument to
1432 2001-05-09 Miguel de Icaza <miguel@ximian.com>
1434 * parameter.cs: Do not use `param' arguments as part of the
1435 signature, per the spec.
1437 2001-05-08 Miguel de Icaza <miguel@ximian.com>
1439 * decl.cs: Base class for classes, structs and interfaces. This
1440 is the "Declaration Space"
1442 * cs-parser.jay: Use CheckDef for checking declaration errors
1443 instead of having one on each function.
1445 * class.cs: Factor out some code for handling error handling in
1446 accordance to the "Declarations" section in the "Basic Concepts"
1447 chapter in the ECMA C# spec.
1449 * interface.cs: Make all interface member classes derive from
1450 InterfaceMemberBase.
1452 2001-05-07 Miguel de Icaza <miguel@ximian.com>
1454 * Many things: all interfaces are parsed and generated in
1455 gen-treedump. Support for member variables, constructors,
1456 destructors, properties, constants is there.
1458 Beginning of the IL backend, but very little done, just there for
1461 2001-04-29 Miguel de Icaza <miguel@ximian.com>
1463 * cs-parser.jay: Fix labeled statement.
1465 * cs-tokenizer.cs (escape): Escape " and ' always.
1466 ref_line, ref_name: keep track of the line/filename as instructed
1467 by #line by the compiler.
1470 2001-04-27 Miguel de Icaza <miguel@ximian.com>
1472 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
1473 to match the values in System.CodeDOM.
1475 Divid renamed to Divide.
1477 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
1479 (Statements.set): remove.
1481 * System.CodeDOM/CodeCatchClause.cs: always have a valid
1484 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
1485 falseStatements always have valid values.
1487 * cs-parser.jay: Use System.CodeDOM now.
