2010-07-08Introduce a new code-completion point prior to an identifier in theDouglas Gregor
selector of an Objective-C method declaration, e.g., given - (int)first:(int)x second:(int)y; this code completion point triggers at the location of "second". It will provide completions that fill out the method declaration for any known method, anywhere in the translation unit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@107929 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-02Move the "current scope" state from the Parser into Action. ThisDouglas Gregor
allows Sema some limited access to the current scope, which we only use in one way: when Sema is performing some kind of declaration that is not directly driven by the parser (e.g., due to template instantiatio or lazy declaration of a member), we can find the Scope associated with a DeclContext, if that DeclContext is still in the process of being parsed. Use this to make the implicit declaration of special member functions in a C++ class more "scope-less", rather than using the NULL Scope hack. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@107491 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-31Minor tweaks on doug's objc recovery patch: the callerChris Lattner
of isSimpleObjCMessageExpression checks the language, so change a dynamic check into an assert. isSimpleObjCMessageExpression is expensive, so only do it in the common case when it is likely to matter: when the [ of the postfix expr starts on a new line. This should avoid doing lookahead for every array expression. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@105229 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-31When we see the a '[' in a postfix expression in Objective-C, performDouglas Gregor
a simple, quick check to determine whether the expression starting with '[' can only be an Objective-C message send. If so, don't parse it as an array subscript expression. This improves recovery for, e.g., [a method1] [a method2] so that we now produce t.m:10:13: error: expected ';' after expression [a method] ^ instead of some mess about expecting ']'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@105221 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-27Implement a code-completion hook for the receiver of an Objective-CDouglas Gregor
message. This completion gives better results than just using the "expression" completion, which is effectively what happened before. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@104895 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-25Improve code completion in failure cases in two ways:Douglas Gregor
1) Suppress diagnostics as soon as we form the code-completion token, so we don't get any error/warning spew from the early end-of-file. 2) If we consume a code-completion token when we weren't expecting one, go into a code-completion recovery path that produces the best results it can based on the context that the parser is in. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@104585 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-23Rework Parser-Sema interface for Objective-C @catch exception objectDouglas Gregor
arguments. Rather than having the parser call ActOnParamDeclarator (which is a bit of a hack), call a new ActOnObjCExceptionDecl action. We'll be moving more functionality into this handler to perform earlier checking of @catch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102222 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-23Improve the AST representation of Objective-C @try/@catch/@finallyDouglas Gregor
statements. Instead of the @try having a single @catch, where all of the @catch's were chained (using an O(n^2) algorithm nonetheless), @try just holds an array of its @catch blocks. The resulting AST is slightly more compact (not important) and better represents the actual language semantics (good). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102221 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-21Implement parsing for message sends in Objective-C++. Message sends inDouglas Gregor
Objective-C++ have a more complex grammar than in Objective-C (surprise!), because (1) The receiver of an instance message can be a qualified name such as ::I or identity<I>::type. (2) Expressions in C++ can start with a type. The receiver grammar isn't actually ambiguous; it just takes a bit of work to parse past the type before deciding whether we have a type or expression. We do this in two places within the grammar: once for message sends and once when we're determining whether a []'d clause in an initializer list is a message send or a C99 designated initializer. This implementation of Objective-C++ message sends contains one known extension beyond GCC's implementation, which is to permit a typename-specifier as the receiver type for a class message, e.g., [typename compute_receiver_type<T>::type method]; Note that the same effect can be achieved in GCC by way of a typedef, e.g., typedef typename computed_receiver_type<T>::type Computed; [Computed method]; so this is merely a convenience. Note also that message sends still cannot involve dependent types or values. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102031 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-21Migrate the responsibility for turning the receiver name in anDouglas Gregor
Objective-C class message expression into a type from the parser (which was doing so in two places) to Action::getObjCMessageKind() which, in the case of Sema, reduces the number of name lookups we need to perform. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102026 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-21Rework the Parser-Sema interaction for Objective-C messageDouglas Gregor
sends. Major changes include: - Expanded the interface from two actions (ActOnInstanceMessage, ActOnClassMessage), where ActOnClassMessage also handled sends to "super" by checking whether the identifier was "super", to three actions (ActOnInstanceMessage, ActOnClassMessage, ActOnSuperMessage). Code completion has the same changes. - The parser now resolves the type to which we are sending a class message, so ActOnClassMessage now accepts a TypeTy* (rather than an IdentifierInfo *). This opens the door to more interesting types (for Objective-C++ support). - Split ActOnInstanceMessage and ActOnClassMessage into parser action functions (with their original names) and semantic functions (BuildInstanceMessage and BuildClassMessage, respectively). At present, this split is onyl used by ActOnSuperMessage, which decides which kind of super message it has and forwards to the appropriate Build*Message. In the future, Build*Message will be used by template instantiation. - Use getObjCMessageKind() within the disambiguation of Objective-C message sends vs. array designators. Two notes about substandard bits in this patch: - There is some redundancy in the code in ParseObjCMessageExpr and ParseInitializerWithPotentialDesignator; this will be addressed shortly by centralizing the mapping from identifiers to type names for the message receiver. - There is some #if 0'd code that won't likely ever be used---it handles the use of 'super' in methods whose class does not have a superclass---but could be used to model GCC's behavior more closely. This code will die in my next check-in, but I want it in Subversion. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102021 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-11fix PR6811 by not parsing 'super' as a magic expression inChris Lattner
LookupInObjCMethod. Doing so allows all sorts of invalid code to slip through to codegen. This patch does not change the AST representation of super, though that would now be a natural thing to do since it can only be in the receiver position and in the base of a ObjCPropertyRefExpr. There are still several ugly areas handling super in the parser, but this is definitely a step in the right direction. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100959 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-11Clean up ownership of 'AttributeList' objects in Parser. ApparentlyTed Kremenek
we would just leak them all over the place, with no clear ownership of these objects at all. AttributeList objects would get leaked on both error and non-error paths. Note: I introduced the usage of llvm::OwningPtr<AttributeList> to manage these objects, which is particularly useful for methods with multiple return sites. In at least one method I used them even when they weren't strictly necessary because it clarified the ownership semantics and made the code easier to read. Should the excessive 'take()' and 'reset()' calls become a performance issue we can always re-evaluate. Note+1: I believe I have not introduced any double-frees, but it would be nice for someone to review this.
