2010-04-24Be more careful around dependent nested-name-specifiers, complainingDouglas Gregor
when they are not complete (since we could not match them up to anything) and ensuring that enum parsing can cope with dependent elaborated-type-specifiers. Fixes PR6915 and PR6649. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102247 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-14Teach typo correction about various language keywords. We can'tDouglas Gregor
generally recover from typos in keywords (since we would effectively have to mangle the token stream). However, there are still benefits to typo-correcting with keywords: - We don't make stupid suggestions when the user typed something that is similar to a keyword. - We can suggest the keyword in a diagnostic (did you mean "static_cast"?), even if we can't recover and therefore don't have a fix-it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101274 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-08Make CXXScopeSpec invalid when incomplete, and propagate that into anyJeffrey Yasskin

2010-03-31Rename CodeModificationHint to FixItHint, since we've been using theDouglas Gregor
term "fix-it" everywhere and even *I* get tired of long names sometimes. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100008 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-10Create a new InjectedClassNameType to represent bare-word references to the John McCall
injected class name of a class template or class template partial specialization. This is a non-canonical type; the canonical type is still a template specialization type. This becomes the TypeForDecl of the pattern declaration, which cleans up some amount of code (and complicates some other parts, but whatever). Fixes PR6326 and probably a few others, primarily by re-establishing a few invariants about TypeLoc sizes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98134 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
2010-02-24ActOnPseudoDestructorExpr now performs all semantic analysis forDouglas Gregor
pseudo-destructor expressions, and builds the CXXPseudoDestructorExpr node directly. Currently, this only affects pseudo-destructor expressions when they are parsed, but not after template instantiation. That's coming next... Improve parsing of pseudo-destructor-names. When parsing the nested-name-specifier and we hit the sequence of tokens X :: ~, query the actual module to determine whether X is a type-name (in which case the X :: is part of the pseudo-destructor-name but not the nested-name-specifier) or not (in which case the X :: is part of the nested-name-specifier). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97058 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
2010-02-05When determining whether a scope specifier is complete, consider aDouglas Gregor

2010-01-19Teach Sema::ActOnDependentTemplateName that a dependent template nameDouglas Gregor
in a member access expression referring into the current instantiation need not be resolved at template definition *if* the current instantiation has any dependent base classes. Fixes PR6081. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93877 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-14When qualified lookup into the current instantiation fails (because itDouglas Gregor
finds nothing), and the current instantiation has dependent base classes, treat the qualified lookup as if it referred to an unknown specialization. Fixes PR6031. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93433 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-19Refactor to remove more dependencies on PreDeclaratorDC. I seem to have madeJohn McCall
the redeclaration problems in the [temp.explicit]p3 testcase worse, but I can live with that; they'll need to be fixed more holistically anyhow. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91771 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-17Carry lookup configuration throughout lookup on the LookupResult. GiveJohn McCall
LookupResult RAII powers to diagnose ambiguity in the results. Other diagnostics (e.g. access control and deprecation) will be moved to automatically trigger during lookup as part of this same mechanism. This abstraction makes it much easier to encapsulate aliasing declarations (e.g. using declarations) inside the lookup system: eventually, lookup will just produce the aliases in the LookupResult, and the standard access methods will naturally strip the aliases off. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89027 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-04When starting a C++ member access expression, make sure to compute theDouglas Gregor
type of the object even when it is dependent. Specifically, this makes sure that we get the right type for "this->", which is important when performing name lookup into this scope to determine whether an identifier or operator-function-id is a template name. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86060 91177308-0d34-0410-b5e6-96231b3b80d8

what we found when we looked into <blah>", where <blah> is a DeclContext*. We can now format DeclContext*'s in nice ways, e.g., "namespace N", "the global namespace", "'class Foo'". This is part of PR3990, but we're not quite there yet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84028 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-24When entering the scope of a declarator, make sure that the scope isDouglas Gregor
complete (or, possibly causing template instantiation). Test this via some explicit specializations of member functions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82732 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-18Implement code completion for tags, e.g., code completion after "enum"Douglas Gregor
will provide the names of various enumerations currently visible. Introduced filtering of code-completion results when we build the result set, so that we can identify just the kinds of declarations we want. This implementation is incomplete for C++, since we don't consider that the token after the tag keyword could start a nested-name-specifier. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82222 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-03Improve template instantiation for member access expressions thatDouglas Gregor
involve qualified names, e.g., x->Base::f. We now maintain enough information in the AST to compare the results of the name lookup of "Base" in the scope of the postfix-expression (determined at template definition time) and in the type of the object expression. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80953 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-02Add a wicked little test-case that illustrates what we have to dealDouglas Gregor
with to properly support member access expressions in templates. This test is XFAIL'd, because we get it completely wrong, but I've made the minimal changes to the representation to at least avoid a crash. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80856 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-02Rewrite of our handling of name lookup in C++ member access expressions, e.g.,Douglas Gregor
x->Base::f We no longer try to "enter" the context of the type that "x" points to. Instead, we drag that object type through the parser and pass it into the Sema routines that need to know how to perform lookup within member access expressions. We now implement most of the crazy name lookup rules in C++ [basic.lookup.classref] for non-templated code, including performing lookup both in the context of the type referred to by the member access and in the scope of the member access itself and then detecting ambiguities when the two lookups collide (p1 and p4; p3 and p7 are still TODO). This change also corrects our handling of name lookup within template arguments of template-ids inside the nested-name-specifier (p6; we used to look into the scope of the object expression for them) and fixes PR4703. I have disabled some tests that involve member access expressions where the object expression has dependent type, because we don't yet have the ability to describe dependent nested-name-specifiers starting with an identifier. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80843 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-30Improve diagnostics for missing members. This renames the ↵Anders Carlsson
err_typecheck_no_member to err_typecheck_no_member_deprecated. The idea is that err_typecheck_no_member_deprecated should be phased out and any call sites that reference it should call DiagnoseMissingMember instead. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80469 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-26Improve diagnostics and recovery when the nested-name-specifier of aDouglas Gregor
qualified name does not actually refer into a class/class template/class template partial specialization. Improve printing of nested-name-specifiers to eliminate redudant qualifiers. Also, make it possible to output a nested-name-specifier through a DiagnosticBuilder, although there are relatively few places that will use this leeway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80056 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-25Improve support for out-of-line definitions of nested templates andDouglas Gregor
their members, including member class template, member function templates, and member classes and functions of member templates. To actually parse the nested-name-specifiers that qualify the name of an out-of-line definition of a member template, e.g., template<typename X> template<typename Y> X Outer<X>::Inner1<Y>::foo(Y) { return X(); } we need to look for the template names (e.g., "Inner1") as a member of the current instantiation (Outer<X>), even before we have entered the scope of the current instantiation. Since we can't do this in general (i.e., we should not be looking into all dependent nested-name-specifiers as if they were the current instantiation), we rely on the parser to tell us when it is parsing a declaration specifier sequence, and, therefore, when we should consider the current scope specifier to be a current instantiation. Printing of complicated, dependent nested-name-specifiers may be somewhat broken by this commit; I'll add tests for this issue and fix the problem (if it still exists) in a subsequent commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80044 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-22Implement support for out-of-line definitions of the class members of classDouglas Gregor
templates, e.g., template<typename T> struct Outer { struct Inner; }; template<typename T> struct Outer<T>::Inner { // ... }; Implementing this feature required some extensions to ActOnTag, which now takes a set of template parameter lists, and is the precursor to removing the ActOnClassTemplate function from the parser Action interface. The reason for this approach is simple: the parser cannot tell the difference between a class template definition and the definition of a member of a class template; both have template parameter lists, and semantic analysis determines what that template parameter list means. There is still some cleanup to do with ActOnTag and ActOnClassTemplate. This commit provides the basic functionality we need, however. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76820 91177308-0d34-0410-b5e6-96231b3b80d8
