2009-09-25Fix checking for a null pointer constant when the expression itself isDouglas Gregor
value-dependent. Audit (and fixed) all calls to Expr::isNullPointerConstant() to provide the correct behavior with value-dependent expressions. Fixes PR5041 and a crash in libstdc++ <locale>. In the same vein, properly compute value- and type-dependence for ChooseExpr. Fixes PR4996. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82748 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-21Remove 'AnalysisContext::setDecl()', as we the Decl associated with anTed Kremenek
AnalysisContext should never change. Along the way, propagate some constness around. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79701 91177308-0d34-0410-b5e6-96231b3b80d8

Convert all clients to use the new predicate on Type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76076 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-30De-ASTContext-ify DeclContext.Argyrios Kyrtzidis
Remove ASTContext parameter from DeclContext's methods. This change cascaded down to other Decl's methods and changes to call sites started "escalating". Timings using pre-tokenized "cocoa.h" showed only a ~1% increase in time run between and after this commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74506 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-30Remove the ASTContext parameter from the getBody() methods of Decl and ↵Argyrios Kyrtzidis
subclasses. Timings showed no significant difference before and after the commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74504 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-30Remove the ASTContext parameter from the attribute-related methods of Decl.Argyrios Kyrtzidis
The implementations of these methods can Use Decl::getASTContext() to get the ASTContext. This commit touches a lot of files since call sites for these methods are everywhere. I used pre-tokenized "carbon.h" and "cocoa.h" headers to do some timings, and there was no real time difference between before the commit and after it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74501 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-18Move the static DeclAttrs map into ASTContext. Fixes <rdar://problem/6983177>.Douglas Gregor

2009-04-23Eliminate the three SmallVectors in ObjCImplDecl (for instanceDouglas Gregor
methods, class methods, and property implementations) and instead place all of these entities into the DeclContext. This eliminates more linear walks when looking for class or instance methods and should make PCH (de-)serialization of ObjCDecls trivial (and lazy). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69849 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-18FunctionDecl::getBody() is getting an ASTContext argument for use inDouglas Gregor
lazy PCH deserialization. Propagate that argument wherever it needs to be. No functionality change, except that I've tightened up a few PCH tests in preparation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69406 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-24Rename NamedDecl::getName() to getNameAsString(). Replace a bunch of Chris Lattner
uses of getName() with uses of getDeclName(). This upgrades a bunch of diags to take DeclNames instead of std::strings. This also tweaks a couple of diagnostics to be cleaner and changes CheckInitializerTypes/PerformInitializationByConstructor to pass around DeclarationNames instead of std::strings. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59947 91177308-0d34-0410-b5e6-96231b3b80d8

Fix PR 2978 false positive for missing release in -dealloc of an ivar retained via a property and then released by assigning nil to that property: http://llvm.org/bugs/show_bug.cgi?id=2978 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58431 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-29Patch by Nikita Zhuk:Ted Kremenek
The attached patch adds additional checks to -warn-objc-missing-dealloc. It checks that all ivars which are used in implementation of synthesized properties are either a) released in dealloc if the property has retain" or "copy" attribute OR b) not released in dealloc if the property has "assign" attribute git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58363 91177308-0d34-0410-b5e6-96231b3b80d8
