2010-03-12Split Sema logic for ObjC @property and @synthesize intoTed Kremenek
a separate file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98317 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-11For ivars created using @synthesize, set their DeclContext to beTed Kremenek
the @implementation (instead of the @interface) and actually add the ivar to the DeclContext (which we weren't doing before). This allows us to simplify ASTContext::CollectNonClassIvars() by removing ASTContext::CollectProtocolSynthesizedIvars(). Now all ivars can be found by either inspecting the ObjCInterfaceDecl and its companion ObjCImplementationDecl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98280 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-01Keep an explicit stack of function and block scopes, each element ofDouglas Gregor
which has the label map, switch statement stack, etc. Previously, we had a single set of maps in Sema (for the function) along with a stack of block scopes. However, this lead to funky behavior with nested functions, e.g., in the member functions of local classes. The explicit-stack approach is far cleaner, and we retain a 1-element cache so that we're not malloc/free'ing every time we enter a function. Fixes PR6382. Also, tweaked the unused-variable warning suppression logic to look at errors within a given Scope rather than within a given function. The prior code wasn't looking at the right number-of-errors count when dealing with blocks, since the block's count would be deallocated before we got to ActOnPopScope. This approach works with nested blocks/functions, and gives tighter error recovery. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97518 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-01Implement jump checking for initialized c++ variables, implementingChris Lattner
a fixme and PR6451. Only perform jump checking if the containing function has no errors, and add the infrastructure needed to do this. On the testcase in the PR, we produce: t.cc:6:3: error: illegal goto into protected scope goto later; ^ t.cc:7:5: note: jump bypasses variable initialization X x; ^ git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97497 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-15Class continuation now has its own property ast forFariborz Jahanian

2010-01-16Improve location information for Objective-C category declarations. WeDouglas Gregor
previously only had a single location (the @ in @interface); now we know where the @ is (for the start of the declaration), where the class name is (that's the normal "location" now for diagnostics), and where the category name is. Also, eliminated the redundant "end" location, since ObjCContainerDecl already has better @end information. The only XFAIL'd test is temporary; will un-XFAIL-it once I've taught CIndex how to use the new locations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93639 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-16Keep track of the source locations for each protocol reference inDouglas Gregor
Objective-C classes, protocol definitions, forward protocol declarations, and categories. This information isn't actually used yet; that's coming next. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93636 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-07Change ObjCContainerDecl to contain the entire range for the '@end'Ted Kremenek
piece of the declaration. The '@' and the 'end' are separate tokens, and require two SourceLocations to accurately track. This change was motivated because ObjCContainerDecl::getSourceRange() would previously not return the entire range of the declaration (the 'end' would be left off). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92891 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.

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

2009-11-17Do not register ObjCInterfaceDecls implicitly created by @class in theTed Kremenek
current DeclContext. These "imaginary" declarations pose issues for clients searching DeclContext for actual declarations. Instead, register them for name lookup, and add the ObjCInterfaceDecl later to the DeclContext when we hit an actual @interface declaration. This also fixes a bug where the invariant that the Decls in a DeclContext are sorted in order of their appearance is no longer violated. What could happen is that an @class causes an ObjCInterfaceDecl to get added first to the DeclContext, then the ObjCClassDecl itself is added, and then later the SourceLocation of the ObjCInterfaceDecl is updated with the correct location (which is later in the file). This breaks an assumed invariant in ResolveLocation.cpp (and possibly other clients). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89160 91177308-0d34-0410-b5e6-96231b3b80d8
