some issues being sorted out. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112493 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-29Implement C++0x user-defined string literals.Sean Hunt
The extra data stored on user-defined literal Tokens is stored in extra allocated memory, which is managed by the PreprocessorLexer because there isn't a better place to put it that makes sure it gets deallocated, but only after it's used up. My testing has shown no significant slowdown as a result, but independent testing would be appreciated. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112458 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-27Propagate whether an id-expression is the immediate argument ofJohn McCall
an '&' expression from the second caller of ActOnIdExpression. Teach template argument deduction that an overloaded id-expression doesn't give a valid type for deduction purposes to a non-static member function unless the expression has the correct syntactic form. Teach ActOnIdExpression that it shouldn't try to create implicit member expressions for '&function', because this isn't a permitted form of use for member functions. Teach CheckAddressOfOperand to diagnose these more carefully. Some of these cases aren't reachable right now because earlier diagnostics interrupt them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112258 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-28The grammar for GNU typeof in C requires an expression to beDouglas Gregor
parenthesized, unlike in C++, e.g., C has: typeof ( expression) C++ has: typeof unary-expression So, once we've parsed a parenthesized expression after typeof, we should only go on to parse the postfix expression suffix if we're in C++. Fixes <rdar://problem/8237491>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109606 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
2010-05-30Improve parser recovery when we try to parse a call expression but theDouglas Gregor
called function itself is invalid (e.g., because of a semantic error referring to that declaration). Fixes <rdar://problem/8044142>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@105175 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-30Teach code completion to adjust its completion priorities based on theDouglas Gregor
type that we expect to see at a given point in the grammar, e.g., when initializing a variable, returning a result, or calling a function. We don't prune the candidate set at all, just adjust priorities to favor things that should type-check, using an ultra-simplified type system. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@105128 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-27When we've parsed a nested-name-specifier in a member accessDouglas Gregor
expression, "forget" about the object type; only the nested-name-specifier matters for name lookup purposes. Fixes PR7239. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@104834 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
2010-05-24improve the fixit for the missing : error when parsing ?:. WhenChris Lattner
there are already two spaces before the token where the : was expected, put the : in between the spaces. This means we get it right in both of these cases: t.c:2:17: error: expected ':' return a ? b c; ^ : t.c:3:16: error: expected ':' return a ? b c; ^ : In the later case, the diagnostic says to insert ": ", in the former case it says to insert ":" between the spaces. This fixes rdar://8007231 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@104569 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-23When parsing a cast-expression that starts with a scope annotation,Douglas Gregor
try to annotate as a type first to determine whether we have a functional-style cast. Patch by Eli Friedman, fixes PR6830. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102161 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
2010-04-21Rework 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

2010-02-25Restore the invariant that a nested-name-specifier can only containDouglas Gregor
class types, dependent types, and namespaces. I had previously weakened this invariant while working on parsing pseudo-destructor expressions, but recent work in that area has made these changes unnecessary. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97112 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-24Rework parsing of pseudo-destructor expressions and explicitDouglas Gregor
destructor calls, e.g., p->T::~T We now detect when the member access that we've parsed, e.g., p-> or x. may be a pseudo-destructor expression, either because the type of p or x is a scalar or because it is dependent (and, therefore, may become a scalar at template instantiation time). We then parse the pseudo-destructor grammar specifically: ::[opt] nested-name-specifier[opt] type-name :: ∼ type-name and hand those results to a new action, ActOnPseudoDestructorExpr, which will cope with both dependent member accesses of destructors and with pseudo-destructor expressions. This commit affects the parsing of pseudo-destructors, only; the semantic actions still go through the semantic actions for member access expressions. That will change soon. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97045 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-21Implement support for parsing pseudo-destructor expression with a ↵Douglas Gregor
nested-name-specifier, e.g., typedef int Int; int *p; p->Int::~Int(); This weakens the invariant that the only types in nested-name-specifiers are tag types (restricted to class types in C++98/03). However, we weaken this invariant as little as possible, accepting arbitrary types in nested-name-specifiers only when we're in a member access expression that looks like a pseudo-destructor expression. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96743 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-10Improve code completion by introducing patterns for the various C andDouglas Gregor
C++ grammatical constructs that show up in top-level (namespace-level) declarations, member declarations, template declarations, statements, expressions, conditions, etc. For example, we now provide a pattern for static_cast<type>(expr) when we can have an expression, or using namespace identifier; when we can have a using directive. Also, improves the results of code completion at the beginning of a top-level declaration. Previously, we would see value names (function names, global variables, etc.); now we see types, namespace names, etc., but no values. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93134 91177308-0d34-0410-b5e6-96231b3b80d8
