2008-10-24Semantic analysis for C++ reinterpret_cast and const_cast. Patch by ↵Douglas Gregor
Sebastian Redl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58094 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-14Add Sema implementation of #pragma pack stack. Daniel Dunbar
- Follows the MSVC (original) implementation, including support of pack(show) (useful for testing). - Implements support for named pack records which gcc seems to ignore (or implements incorrectly). - Not currently wired to anything, only functionality change is the type checking of the pragma. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@57476 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-02Add support for format string checking of object-size checkingDaniel Dunbar
versions of sprintf and friends. - Added FIXME that this mechanism should be generalized. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56962 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-09Add a LangOptions member to IdentifierResolver.Argyrios Kyrtzidis
Make Sema pass the LangOptions to IdentifierResolver's constructor. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56015 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-09Tweak implementation for allowing ObjC builtin type redefinitions.Steve Naroff
- Replace string comparisons with pre-defined idents. - Avoid calling isBuiltinObjCType() to avoid two checks. - Remove isBuiltinObjCType(), since it was only used in Sema::MergeTypeDefDecl(). - Have Sema::MergeTypeDefDecl() set the new type. This is a moidified version of an patch by David Chisnall. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55990 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-05Remove "NextDecl" from RecordDecl. This change touches many files that ↵Ted Kremenek
where RecordDecl or CXXRecordDecl was constructed, always with an argument of 'NULL' for the previous declaration. The motivation behind this change is that chaining the RecordDecls is simply unnecessary. Once we create multiple RecordDecls for the same struct/union/class, clients that care about all the declarations of the same struct can build a back map by seeing which Decls refer to the same RecordType. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55821 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-04Generate error if we try to implicit cast between different addressMon P Wang
spaces git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55765 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-03Add semantic analysis for "blocks". Steve Naroff
Highlights... - 4 new AST nodes, BlockExpr, BlockStmtExpr, BlockExprExpr, BlockDeclRefExpr. - Sema::ActOnBlockStart(), ActOnBlockError(), ActOnBlockStmtExpr(), ActOnBlockExprExpr(), ActOnBlockReturnStmt(). Next steps... - hack Sema::ActOnIdentifierExpr() to deal with block decl refs. - add attribute handler for byref decls. - add test cases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55710 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-24Pass SourceRanges by reference to the various Diag methods.Argyrios Kyrtzidis
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55284 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-23Make sure to create CXX record decls for the implicit Obj-C type ↵Anders Carlsson
declarations. This lets us compile Cocoa.h as Objective-C++ git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55261 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-23make sure that ParseAST invokes the action for end of translation unit.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55222 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-23minor cleanup, remove finalize method.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55216 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-14Change Parser & Sema to use interned "super" for comparions.Daniel Dunbar
- Added as private members for each because it is not clear where to put the common definition. Perhaps the IdentifierInfos all of these "pseudo-keywords" should be collected into one place (this would KnownFunctionIDs and Objective-C property IDs, for example). Remove Token::isNamedIdentifier. - There isn't a good reason to use strcmp when we have interned strings, and there isn't a good reason to encourage clients to do so. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54794 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-11More #include cleaningDaniel Dunbar
- Kill unnecessary #includes in .cpp files. This is an automatic sweep so some things removed are actually used, but happen to be included by a previous header. I tried to get rid of the obvious examples and this was the easiest way to trim the #includes in one fell swoop. - We now return to regularly scheduled development. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54632 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-11More #include cleaningDaniel Dunbar
- Drop {Decl.h,DeclObjC.h,IdentifierTable.h} from Expr.h - Moved Sema::getCurMethodDecl() out of line (dependent on ObjCMethodDecl via dyn_cast). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54629 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-11More #include cleaningDaniel Dunbar
- Drop Expr.h,RecordLayout.h from ASTContext.h (for DeclBase.h and SourceLocation.h) - Move ASTContext constructor into implementation git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54627 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-26change more instances of QualType::getCanonicalType to callChris Lattner
ASTContext::getCanonicalType instead (PR2189) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54105 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-24Move isObjCObjectPointerType() from Sema to ASTContext.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53998 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-21Switch initialization of the protocol list for an interface decl to useChris Lattner
the standard "set these as the list of protocols" interface instead of a strange "set this as the size and then set each one to the value" interface. The problem with the later is that it a) is completely different from everything else, b) is awkward, and c) doesn't handle the case when a referenced protocol is invalid: it set it to null. This meant that all clients downstream would have to handle null protocols in the protocol list, and empirically they didn't. Fix this by not setting invalid protocols in the referenced protocol list, fixing the crash on test/Sema/objc-interface-1.m While I'm at it, clean up some locations so that we produce: t.m:1:25: error: cannot find interface declaration for 'NSObject', superclass of 'NSWhatever' @interface NSWhatever : NSObject <NSCopying> ~~~~~~~~~~~~~~~~~~~~~ ^ instead of: t.m:1:1: error: cannot find interface declaration for 'NSObject', superclass of 'NSWhatever' @interface NSWhatever : NSObject <NSCopying> ^ git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53846 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-21minor rename, also, reject pointer to qualified id.Chris Lattner
id<NSCopyable>* is not an "objc pointer type", id<NSCopyable> is. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53820 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-21Fix a crash that can happen when you have typedefs for pointers toChris Lattner
interfaces. Just because they x->isPointerType() doesn't mean it is valid to just cast to a pointertype. We have to handle typedefs etc as well. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53819 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-21simplify this predicate, only checking isObjCQualifiedIdType once.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53817 91177308-0d34-0410-b5e6-96231b3b80d8

2008-06-28Replace CurFunctionDecl and CurMethodDecl with methods getCurFunctionDecl() ↵Argyrios Kyrtzidis
and getCurMethodDecl() that return the appropriate Decl through CurContext. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@52852 91177308-0d34-0410-b5e6-96231b3b80d8

2008-06-21"This moves built-in Objective-C types up the scope chains to where they can ↵Chris Lattner
be replaced by versions included from the runtime library's headers." This makes it ok to use @"foo" without a declaration for NSConstantString. Patch by David Chisnall! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@52593 91177308-0d34-0410-b5e6-96231b3b80d8

2008-06-09-Changes to TagDecl:Argyrios Kyrtzidis
Added TagKind enum. Added getTagKind() method. Added convenience methods: isEnum(), isStruct(), isUnion(), isClass(). -RecordDecl/CXXRecordDecl::Create() accept a TagKind enum instead of a DeclKind one. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@52160 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-17Addition of TranslationUnitDecl to the AST:Argyrios Kyrtzidis
-Added TranslationUnitDecl class to serve as top declaration context -ASTContext gets a TUDecl member and a getTranslationUnitDecl() function -All ScopedDecls get the TUDecl as DeclContext when declared at global scope git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49855 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-12Added PushOnScopeChains method to Sema, that adds a decl to both the ↵Argyrios Kyrtzidis
IdResolver and the Scope. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49567 91177308-0d34-0410-b5e6-96231b3b80d8

shadowing, instead of threading it through the AST. This patch contributed by Argiris Kirtzidis! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49520 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-06This patch contains these changes:Chris Lattner
-Renamed ContextDecl -> DeclContext -Removed DeclContext pointer from FieldDecl -EnumDecl inherits from DeclContext, instead of TagDecl Patch by Argiris Kirtzidis! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49261 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-04Introduce ContextDecl, patch by Argiris Kirtzidis!Chris Lattner
-Added ContextDecl (no TranslationUnitDecl) -ScopedDecl class has a ContextDecl member -FieldDecl class has a ContextDecl member, so that a Field or a ObjCIvar can be traced back to their RecordDecl/ObjCInterfaceDecl easily -FunctionDecl, ObjCMethodDecl, TagDecl, ObjCInterfaceDecl inherit from ContextDecl. With TagDecl as ContextDecl, enum constants have a EnumDecl as their context. -Moved Decl class to a "DeclBase.h" along with ContextDecl class -CurContext is handled by Sema git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49208 91177308-0d34-0410-b5e6-96231b3b80d8

allocation through ASTContext. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48403 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-15Make a major restructuring of the clang tree: introduce a top-levelChris Lattner
lib dir and move all the libraries into it. This follows the main llvm tree, and allows the libraries to be built in parallel. The top level now enforces that all the libs are built before Driver, but we don't care what order the libs are built in. This speeds up parallel builds, particularly incremental ones. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48402 91177308-0d34-0410-b5e6-96231b3b80d8
