2008-11-19Switch several more Sema Diag methods over. This simplifies theChris Lattner
__builtin_prefetch code to only emit one diagnostic per builtin_prefetch. While this has nothing to do with the rest of the patch, the code seemed like overkill when I was updating it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59588 91177308-0d34-0410-b5e6-96231b3b80d8

2008-09-30Fix <rdar://problem/6191148> [sema] Objective-C method lookup (at global ↵Steve Naroff
scope) fails to handle overloaded selectors properly. Long standing bug in Sema::ActOnInstanceMessage(). We now warn when messaging an "id" with multiple method signatures in scope. The diags are a little verbose, however they can be streamlined if necessary. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56843 91177308-0d34-0410-b5e6-96231b3b80d8

2008-09-11Fix two bugs exposed by array passing assert:Daniel Dunbar
(1) Additional arguments to variadic methods should have default promotions applied. (2) Additional arguments to non-variadic methods were allowed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56084 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-11Bug fix, apply default argument promotion in message sends for whichDaniel Dunbar
no method declaration was found. - This was allowing arrays to pass "by value" among other things. Add assert in CodeGen that arguments cannot have array type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56080 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

2008-07-25Cleaunup Sema::ActOnClassMessage(). This commit:Steve Naroff
(a) removes a bogus warning. (b) removes an undesirable usage of the ObjCMessageExpr constructor that takes an IdentifierInfo * (which I will abolish). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54042 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-24Fix Sema::ActOnClassMessage() to pass through the identifier for "super". Steve Naroff
This fixes a critical rewriter bug (<rdar://problem/6096760> clang ObjC rewriter: 'self' not expected value in class method called with 'super'). Also added a couple FIXME's since I'm not happy with my fix to Sema. It would be nicer if the super handling for class/instance messages was the same (based on PreDefinedExpr). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53994 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-21continue cleaning up code, and disable sending a message directly to anChris Lattner

2008-06-24ObjCMessageExpr objects that represent messages to class methods now can ↵Ted Kremenek
contain the ObjCInterfaceDecl* of the target class if it was available when the ObjCMessageExpr object was constructed. The original interfaces of the class has been preserved (requiring no functionality changes from clients), but now a "getClasSInfo" method returns both the ObjCInterfaceDecl* and IdentifierInfo* of the target class. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@52676 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-21"this patch adds code generation hooks for Objective-C constant strings. It ↵Chris Lattner
also modifies Sema so that Objective-C constant strings are treated as untyped objects if the interface for the constant string class can not be found. This is consistent with Apple GCC. I thought it was consistent with GNU GCC, since this was causing failures when trying to compile GNUstep with (GNU) GCC, but it appears that this is not the case when attempting to produce a simple test case to demonstrate it. Possibly there is a way of making the error go away, but I haven't found out what it is yet."

deleting dead code, making other code more obvious, and fixing a bug. This fixes these (bogus) warnings in release mode: SemaExprObjC.cpp:383: warning: 'RHSProtoE' may be used uninitialized in this function SemaExprObjC.cpp:383: warning: 'RHSProtoI' may be used uninitialized in this function git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49984 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-07move ObjCQualifiedIdTypesAreCompatible out of ASTContext into Sema.Chris Lattner
While it is similar to the other compatibility predicates in ASTContext, it is not used by them and is different. In addition, greatly simplify ObjCQualifiedIdTypesAreCompatible and fix some canonical type bugs. Also, simplify my Type::getAsObjC* methods. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49313 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-02Two changes to Sema::LookupDecl() interface. Steve Naroff
(1) Remove IdLoc (it's never used). (2) Add a bool to enable/disable lazy builtin creaation (defaults to true). This enables us to use LookupDecl() in Sema::isTypeName(), which is also part of this commit. To make this work, I changed isTypeName() to be a non-const member function. I'm not happy with this, however I fiddled with making LookupDecl() and friends const and it got ugly pretty quickly. We can certainly add it back if/when someone has time to fiddle with it. For now, I thought this simplification was more important than retaining the const-ness. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49087 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-01Fairly large "cleaup" related to changing ObjCCompatibleAliasDecl superclass ↵Steve Naroff
(to inherit from NamedDecl, instead of ScopedDecl). - Added a DenseMap to associate an IdentifierInfo with the ObjCCompatibleAliasDecl. - Renamed LookupScopedDecl->LookupDecl and changed it's return type to Decl. Also added lookup for ObjCCompatibleAliasDecl's. - Removed Sema::LookupInterfaceDecl(). Converted clients to used LookupDecl(). - Some minor indentation changes. Will deal with ObjCInterfaceDecl and getObjCInterfaceDecl() in a separate commit... git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49058 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
