2010-02-23More support for ivars in class extension.Fariborz Jahanian

2010-02-21Clang really intends to reject attribute 'warn_unused_result' on Objective-C ↵Ted Kremenek
methods, but instead it crashes on them. We might extend this attribute to work on methods, but for now fix the crasher. Addresses <rdar://problem/7670939>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96723 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-15Class continuation now has its own property ast forFariborz Jahanian
those declared in it. This is to allow duplicate property diagnostics for properties declared in class extensions multiple times (radar 7629420) and for future use. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96276 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-12Patch to fix a warning which exposed a bug in buildingFariborz Jahanian

2010-02-08Merge block/function pointer types with objc's __weakFariborz Jahanian
attribute properly and avoid bogus warning. This is an objective-c fix only. objective-c++ follows different code pass and requires separate fix (which will come at a later time). Fixes radar 7214820. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95571 91177308-0d34-0410-b5e6-96231b3b80d8

pointing to the declaration that we found that has that name (if it is unique). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92877 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-06When suggesting a typo correction for an @implementation without aDouglas Gregor
corresponding @interface, provide a note showing which interface we're referring to. This note has the fix-it hint on it. Also, don't automatically apply fix-it hints for notes. They're meant to express fix-its that would change semantics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92870 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-04When declaring an Objective-C implementation without a correspondingDouglas Gregor
interface, suggest correction of typos. For example, given: @interface NSString @end @implementation NSstring @end we'll warn with: t.m:4:19: warning: cannot find interface declaration for 'NSstring'; did you mean 'NSString'? @implementation NSstring ^ However, since this is just a warning, we don't provide a fix-it hint. Good idea, Ted! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92488 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-03Implement typo correction for a variety of Objective-C-specificDouglas Gregor
constructs: - Instance variable lookup ("foo->ivar" and, in instance methods, "ivar") - Property name lookup ("foo.prop") - Superclasses - Various places where a class name is required - Protocol names (e.g., id<proto>) This seems to cover many of the common places where typos could occur. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92449 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-16Add abort() as a builtin. This has two effects: one, we warn for incorrect Eli Friedman
declarations of abort(), and two, we mark it noreturn. Missing the latter shows up in one of the "embarassing" tests (from the thread on llvmdev "detailed comparison of generated code size for LLVM and other compilers"). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91515 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-15Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.Daniel Dunbar
- This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91446 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-21"Incremental" progress on using expressions, by which I mean totally rippingJohn McCall
into pretty much everything about overload resolution in order to wean BuildDeclarationNameExpr off LookupResult::getAsSingleDecl(). Replace UnresolvedFunctionNameExpr with UnresolvedLookupExpr, which generalizes the idea of a non-member lookup that we haven't totally resolved yet, whether by overloading, argument-dependent lookup, or (eventually) the presence of a function template in the lookup results. Incidentally fixes a problem with argument-dependent lookup where we were still performing ADL even when the lookup results contained something from a block scope. Incidentally improves a diagnostic when using an ObjC ivar from a class method. This just fell out from rewriting BuildDeclarationNameExpr's interaction with lookup, and I'm too apathetic to break it out. The only remaining uses of OverloadedFunctionDecl that I know of are in TemplateName and MemberExpr. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89544 91177308-0d34-0410-b5e6-96231b3b80d8
