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

129 operators are found instead of making noise ;-)
130 (Unary::ResolveOperator): New method to do precisely the same thing which
131 Binary::ResolveOperator does for Binary expressions.
132 (Unary.method, .Arguments): Add.
133 (Unary::OperName): Implement.
134 (Unary::ForceConversion): Copy and Paste !
136 * class.cs (Operator::Define): Fix a small bug for the case when we have
139 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
140 for the inbuilt operators. Only overloading works for now ;-)

160 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
161 the last instruction contains a return opcode to avoid generating
162 the last `ret' instruction (this generates correct code, and it is
163 nice to pass the peverify output).
165 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
166 initializer for static and instance variables.
167 (Constructor::Emit): Allow initializer to be null in the case of
168 static constructors. Only emit initializer for instance
171 (TypeContainer::FindMembers): Return a null array if there are no
174 Also fix the code for the MemberTypes.Method branch, as it was not
175 scanning that for operators (or tried to access null variables before).

221 * expression.cs (Expression::OverloadResolve): Drop TypeContainer
224 (Expression::MemberLookup): Provide a version that allows to
225 specify the MemberTypes and BindingFlags.

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

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

343 * driver.cs: Added --parse option that only parses its input files
346 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
347 incorrect. IsTopLevel is not used to tell whether an object is
348 root_types or not (that can be achieved by testing this ==
349 root_types). But to see if this is a top-level *class* (not
350 necessarly our "toplevel" container).
352 2001-09-14 Ravi Pratap <ravi@ximian.com>
354 * enum.cs (Enum::Define): Modify to call the Lookup method on the
355 parent instead of a direct call to GetType.
357 2001-09-14 Ravi Pratap <ravi@ximian.com>
359 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
360 Modifiers.TypeAttr. This should just be a call to that method.

373 (TypeContainer::HaveStaticConstructor): New property to provide access
374 to precisely that info.
376 * modifiers.cs (MethodAttr): Re-write.
377 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
379 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
380 of top-level types as claimed.
382 2001-09-13 Miguel de Icaza <miguel@ximian.com>
384 * expression.cs (MemberLookup): Fruitless attempt to lookup
385 constructors. Maybe I need to emit default constructors? That
386 might be it (currently .NET emits this for me automatically).
387 (Invocation::OverloadResolve): Cope with Arguments == null.
388 (Invocation::EmitArguments): new function, shared by the new
390 (Invocation::Emit): Handle static and instance methods. Emit

402 SimpleLookup): Auxiliary routines to help parse a qualifier
405 Update qualifier_identifier rule.
407 * codegen.cs: Removed debugging messages.

414 * expression.cs (PropertyExpr): Initialize type from the
417 * codegen.cs (EmitContext::EmitBoolExpression): Use propper
418 Resolve pattern. Attempt to implicitly convert value to boolean.

422 (Binary::ResolveOperator): Set the return type to boolean for
423 comparission operators
425 * typemanager.cs: Remove debugging print code.
427 (Invocation::Resolve): resolve type.
429 * class.cs: Allocate a MemberInfo of the correct size, as the code
430 elsewhere depends on the test to reflect the correct contents.
432 (Method::) Keep track of parameters, due to System.Reflection holes
434 (TypeContainer::Populate): Keep track of MethodBuilders to Method
437 (TypeContainer::FindMembers): Use ArrayList and then copy an array
438 of the exact size and return that.
440 (Class::LookupMethodByBuilder): New function that maps
441 MethodBuilders to its methods. Required to locate the information
442 on methods because System.Reflection bit us again.
444 * support.cs: New file, contains an interface ParameterData and
445 two implementations: ReflectionParameters and InternalParameters
446 used to access Parameter information. We will need to grow this
449 * expression.cs (Invocation::GetParameterData): implement a cache
450 and a wrapper around the ParameterData creation for methods.
451 (Invocation::OverloadResolve): Use new code.
453 2001-09-13 Ravi Pratap <ravi@ximian.com>

464 initialized with the full type once it is resolved.
466 2001-09-12 Miguel de Icaza <miguel@ximian.com>
468 * parameter.cs (GetParameterInfo): Use a type cache to compute
469 things only once, and to reuse this information

472 (OpcodeCast::Emit): fix.
474 (ParameterReference::Resolve): Implement.
475 (ParameterReference::Emit): Implement.

510 what Type.FindMembers does, only we don't have to use reflection. No
513 * typemanager.cs (typecontainers): New hashtable to hold the corresponding
514 typecontainer objects as we need to get at them.
515 (TypeManager::AddUserType): Overload to take an extra argument, the TypeContainer.
517 * rootcontext.cs : Correspondingly modify called to AddUserType to pass the
518 typecontainer object.
520 * expression.cs (MemberLookup): Modify signature to take a RootContext object instead
521 of just a Report object.
523 2001-09-11 Ravi Pratap <ravi@ximian.com>

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

1033 on Expression Classification. Now all expressions have a method
1034 `Resolve' and a method `Emit'.

1037 generation from working. Also add some temporary debugging
1040 2001-08-24 Miguel de Icaza <miguel@ximian.com>

1080 and made a method, optional argument tells whether this is a class
1081 or a structure to apply the `has-this' bit.

1193 * driver.cs: Make sure we always load mscorlib first (for
1194 debugging purposes, nothing really important).
1196 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
1197 have moved to `CSC' rather than `CIR'. Oh man! The confussion!

1264 RecordInterface instead.
1266 * cs-parser.jay: Updated to reflect changes above.
1268 * decl.cs (Definition): Keep track of the TypeBuilder type that
1269 represents this type here. Not sure we will use it in the long
1270 run, but wont hurt for now.

1334 post_decrement_expression to reduce a shift/reduce.
1336 2001-07-11 Simon Cozens
1338 * cs-tokenizer.cs: Hex numbers should begin with a 0.
1340 Improve allow_keyword_as_indent name.
1342 2001-06-19 Miguel de Icaza <miguel@ximian.com>
1344 * Adjustments for Beta2.
1346 2001-06-13 Miguel de Icaza <miguel@ximian.com>
1348 * decl.cs: Added `Define' abstract method.
1349 (InTransit): new property, used to catch recursive definitions.
1351 * interface.cs: Implement `Define'.
1353 * modifiers.cs: Map Modifiers.constants to
1354 System.Reflection.TypeAttribute flags.
1356 * class.cs: Keep track of types and user-defined types.
1357 (BuilderInit): New method for creating an assembly
1358 (ResolveType): New function to launch the resolution process, only
1359 used by interfaces for now.
1361 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
1362 that are inserted into the name space.
1364 2001-06-08 Miguel de Icaza <miguel@ximian.com>
1366 * ARGH. I have screwed up my tree so many times due to the use of
1367 rsync rather than using CVS. Going to fix this at once.
1369 * driver.cs: Objetify driver. Load assemblies, use assemblies to
1372 2001-06-07 Miguel de Icaza <miguel@ximian.com>
1374 * Experiment successful: Use System.Type rather that our own
1377 2001-05-25 Miguel de Icaza <miguel@ximian.com>
1379 * cs-parser.jay: Removed nsAliases from here.
1381 Use new namespaces, handle `using XXX;'
1383 * namespace.cs: Reimplemented namespace handling, use a recursive
1384 definition of the class. Now we can keep track of using clauses
1385 and catch invalid using clauses.
1387 2001-05-24 Miguel de Icaza <miguel@ximian.com>
1389 * gen-treedump.cs: Adapted for all the renaming.
1391 * expression.cs (Expression): this class now has a Type property
1392 which returns an expression Type.
1394 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
1395 `Type', as this has a different meaning now in the base
1397 2001-05-22 Miguel de Icaza <miguel@ximian.com>
1399 * interface.cs, class.cs: Removed from all the sources the
1400 references to signature computation, as we can not do method
1401 signature computation during the parsing time, as we are not
1402 trying to solve at that point distinguishing:
1406 void a (NS.Blah x) {}
1409 Which depending on the context might be valid or not, as we do not
1410 know if Blah is the same thing as NS.Blah at that point.
1412 * Redid everything so the code uses TypeRefs now instead of
1413 Types. TypeRefs are just temporary type placeholders, that need
1414 to be resolved. They initially have a pointer to a string and the
1415 current scope in which they are used. This is used later by the
1416 compiler to resolve the reference to an actual Type.
1418 * DeclSpace is no longer a CIR.Type, and neither are
1419 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
1420 are all DeclSpaces, but no Types.
1422 * type.cs (TypeRefManager): This implements the TypeRef manager,
1423 which keeps track of all the types that need to be resolved after
1424 the parsing has finished.
1426 2001-05-13 Miguel de Icaza <miguel@ximian.com>
1428 * ARGH. We are going to have to store `foreach' as a class rather
1429 than resolving it, as we need to verify error 1579 after name
1430 resolution. *OR* we could keep a flag that says `This request to
1431 IEnumerator comes from a foreach statement' which we can then use
1432 to generate the error.
1434 2001-05-10 Miguel de Icaza <miguel@ximian.com>
1436 * class.cs (TypeContainer.AddMethod): we now add methods to the
1437 MethodGroup instead of the method hashtable.
1439 * expression.cs: Add MethodGroup abstraction, which gets us one
1440 step closer to the specification in the way we handle method
1443 * cs-parser.jay (primary_expression): qualified_identifier now
1444 tried to match up an identifier to a local variable reference or
1445 to a parameter reference.
1447 current_local_parameters is now a parser global variable that
1448 points to the current parameters for the block, used during name
1451 (property_declaration): Now creates an implicit `value' argument to
1454 2001-05-09 Miguel de Icaza <miguel@ximian.com>
1456 * parameter.cs: Do not use `param' arguments as part of the
1457 signature, per the spec.
1459 2001-05-08 Miguel de Icaza <miguel@ximian.com>
1461 * decl.cs: Base class for classes, structs and interfaces. This
1462 is the "Declaration Space"
1464 * cs-parser.jay: Use CheckDef for checking declaration errors
1465 instead of having one on each function.
1467 * class.cs: Factor out some code for handling error handling in
1468 accordance to the "Declarations" section in the "Basic Concepts"
1469 chapter in the ECMA C# spec.
1471 * interface.cs: Make all interface member classes derive from
1472 InterfaceMemberBase.
1474 2001-05-07 Miguel de Icaza <miguel@ximian.com>
1476 * Many things: all interfaces are parsed and generated in
1477 gen-treedump. Support for member variables, constructors,
1478 destructors, properties, constants is there.
1480 Beginning of the IL backend, but very little done, just there for
1483 2001-04-29 Miguel de Icaza <miguel@ximian.com>
1485 * cs-parser.jay: Fix labeled statement.
1487 * cs-tokenizer.cs (escape): Escape " and ' always.
1488 ref_line, ref_name: keep track of the line/filename as instructed
1489 by #line by the compiler.
1492 2001-04-27 Miguel de Icaza <miguel@ximian.com>
1494 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
1495 to match the values in System.CodeDOM.
1497 Divid renamed to Divide.
1499 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
1501 (Statements.set): remove.
1503 * System.CodeDOM/CodeCatchClause.cs: always have a valid
1506 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
1507 falseStatements always have valid values.
1509 * cs-parser.jay: Use System.CodeDOM now.
