2007-10-16Fix location processing of @encode: the range should include the @ sign.Chris Lattner
@selector probably gets this wrong also. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43048 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-16Add a new Rewriter::getRangeSize method.Chris Lattner
Rename SourceRange::Begin()/End() to getBegin()/getEnd() for consistency with other code. Start building the rewriter towards handling @encode. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43047 91177308-0d34-0410-b5e6-96231b3b80d8

2007-10-16Remove ObjcMethodDecl::getNumMethodParams/getMethodParamDecl, they aren't ↵Steve Naroff
used/needed. Change ObjcMethodDecl::getMethodType to getResultType, to match FunctionDecl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43045 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-16Patch to implement AST generation for objective-c's @selector expression.Fariborz Jahanian
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43038 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-16Emit diagnostics for methods not found.Steve Naroff
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43037 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-16initialization of references should not do default fn/array promotions.Chris Lattner
This fixes a bug Anders noticed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43024 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-16Bad cast...need to use dyn_cast_or_null. Also changed ↵Steve Naroff
Sema::InitBuiltinVaListType (which had the same bug). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43023 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-15Change the type of ObjCStringLiteral from "struct __builtin_CFString *" to ↵Steve Naroff
"NSConstantString *". This makes the typecheck much happier. Without this change, the type checker would have to special case "struct __builtin_CFString *". This change does assume the interface for NSConstantString is declared in the translation unit. I left ASTContext::getCFConstantStringType() around for now (with a comment that says it is currently unused). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43021 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-15Move type compatibility predicates from Type to ASTContext. In addition, the ↵Steve Naroff
predicates are now instance methods (they were previously static class methods on Type). This allowed me to fix the following hack from this weekend... // FIXME: Devise a way to do this without using strcmp. // Would like to say..."return getAsStructureType() == IdStructType;", but // we don't have a pointer to ASTContext. bool Type::isObjcIdType() const { if (const RecordType *RT = getAsStructureType()) return !strcmp(RT->getDecl()->getName(), "objc_object"); return false; } ...which is now... bool isObjcIdType(QualType T) const { return T->getAsStructureType() == IdStructType; } Side notes: - I had to remove a convenience function from the TypesCompatibleExpr class. int typesAreCompatible() const {return Type::typesAreCompatible(Type1,Type2);} Which required a couple clients get a little more verbose... - Result = TCE->typesAreCompatible(); + Result = Ctx.typesAreCompatible(TCE->getArgType1(), TCE->getArgType2()); Overall, I think this change also makes sense for a couple reasons... 1) Since ASTContext vends types, it makes sense for the type compatibility API to be there. 2) This allows the type compatibility predeciates to refer to data not strictly present in the AST (which I have found problematic on several occasions). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43009 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-15Add code generation and sema checking for __builtin_va_arg.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43006 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-15Several name lookup conflict detection fixes involving objective-c names.Fariborz Jahanian
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43000 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-15Added ASTContext::setObjcIdType/getObjcIdType(), set by Sema.Steve Naroff
Also noticed ASTContext::BuiltinVaListType wasn't being initialized to the null type (so I set it). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42983 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-15Add support for Pascal strings.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42974 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-14- Teach ObjcInterfaceDecl::lookupInstance/ClassMethod to look through protocols.Steve Naroff
- Start looking up methods in the global method pools (for "id"). - Start integrating interface types into the type system. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42971 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-14Add category lookup (removing a couple FIXME's).Steve Naroff
Changed ObjcInterfaceDecl::ListCategories->CategoryList. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42968 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-14- Added Sema::AddFactoryMethodToGlobalPool and ↵Steve Naroff
Sema::AddInstanceMethodToGlobalPool and DenseMaps. This will allow us to efficiently lookup a method from a selector given no type information (for the "id" data type). - Fixed some funky "} else {" indentation in Sema::ActOnAddMethodsToObjcDecl(). I'd prefer we stay away from this style...it wastes space and isn't any easier to read (from my perspective, at least:-) - Changed Parser::ParseObjCInterfaceDeclList() to only call Action::ActOnAddMethodsToObjcDecl() when it actually has methods to add (since most interface have methods, this is a very minor cleanup). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42957 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42938 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-12Check and diagnose that objective-c objects may not be statically allocated.Fariborz Jahanian
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42936 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-12Added notion of '*' specified format width/specifiers when checkingTed Kremenek
printf format strings. Added type checking to see if the matching width/precision argument was of type 'int'. Thanks to Anders Carlsson for reporting this missing feature. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42933 91177308-0d34-0410-b5e6-96231b3b80d8

2007-10-12Fixed a @compatible_alias bug. In the process, discovered unnecessary 2ndry ↵Fariborz Jahanian
lookup ok class names and streamlined this logic to do the lookup once. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42926 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-12Replace one FIXME with another. We handle protocols just fine now. The ObjC ↵Steve Naroff
decl will only be 0 when we have an error on the ObjC decl. I would prefer we pass in a decl that is marked as invalid. I don't think this is critical to fix now, however I'd like us to be consistent. There are currently many places that don't mark the decl as invalid (which need to be fixed)... git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42923 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-12Add some more diagnostics for va_start, fix tests so they pass with these ↵Anders Carlsson
new diags. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42917 91177308-0d34-0410-b5e6-96231b3b80d8

2007-10-10Refinements to Sema::GetObjcIdType()...Steve Naroff
- Cache the typedef, not the type (avoids importing AST/Type.h). - Emit an error if "id" cannot be found. - Comment the routine and add a FIXME to reconsider how we emulate GCC's new fangled behavior. This isn't a priority for now, since almost no code depends on having "id" built-in. - Add a test. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42845 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-10- Make sure default return/argument types (for methods) default to "id".Steve Naroff
- Cache the "id" type in Sema...initialize ObjcIdType and TUScope (oops). - Fix ActOnInstanceMessage to allow for "id" type receivers...still work to do (next). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42842 91177308-0d34-0410-b5e6-96231b3b80d8

2007-10-10Remove Scope argument from ObjC actions that either don't need it or can now ↵Steve Naroff
use TUScope. Also improve a recently added comment. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42826 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-09Make a significant change to invert the control flow handlingChris Lattner
predefined macros. Previously, these were handled by the driver, now they are handled by the preprocessor. Some fallout of this: 1. Instead of preprocessing two buffers (the predefines, then the main source file) we now start preprocessing the main source file and inject the predefines as a "psuedo #include" from the main source file. 2. #1 allows us to nuke the Lexer::IsMainFile flag and simplify Preprocessor::isInPrimaryFile. 3. The driver doesn't have to know about standard #defines, the preprocessor knows, which is nice for people wanting to define their own drivers. 4. This allows us to put normal tokens in the predefine buffer, for example a definition for __builtin_va_list that is target-specific, and a typedef for id in objc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42818 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-09Make sure methods with no return type default to "id".Steve Naroff
This fixes a crasher in Sema::MatchTwoMethodDeclarations(), identified by selector-overload.m (just added). Added Action::ActOnTranslationUnitScope() and renamed Action::PopScope to ActOnPopScope. Added a Translation Unit Scope instance variable to Sema (will be very useful to ObjC-related actions, since ObjC declarations are always file-scoped). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42817 91177308-0d34-0410-b5e6-96231b3b80d8

2007-10-09Update DeclKind enums to reflect ObjcProtocolDecl's inheritance change.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42802 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-09Remove addition of protocol names to declaration scopes, use a separateFariborz Jahanian
DenseMap to keep track of such declarations and derive ObjcProtocolDecl directyly from NamedScope. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42801 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-09rename some "Parse" actions to "ActOn". Move code around inChris Lattner
ParseFunctionDefinition so that ActOnFunctionDefBody is always called if ActOnStartOfFunctionDef is called. This fixes a crash reported by Nuno Lopes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42793 91177308-0d34-0410-b5e6-96231b3b80d8

2007-10-08Convert Selector Maps/Sets to use stronger typing (now that we have ↵Steve Naroff
DenseMapInfo in IdentifierTable.h). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42767 91177308-0d34-0410-b5e6-96231b3b80d8

2007-10-06introduce a new NamedDecl class, switch a couple of things over to using it.Chris Lattner
NamedDecl is a Decl that has an IdentifierInfo (for example, ScopedDecl), but not ObjcMethodDecl. Simplify some code in ActOnAddMethodsToObjcDecl, by doing the cast from DeclTy to Decl at the start of the method. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42710 91177308-0d34-0410-b5e6-96231b3b80d8
