2009-11-03Replace the code that parses member access expressions after "." orDouglas Gregor
"->" with a use of ParseUnqualifiedId. Collapse ActOnMemberReferenceExpr, ActOnDestructorReferenceExpr (both of them), ActOnOverloadedOperatorReferenceExpr, ActOnConversionOperatorReferenceExpr, and ActOnMemberTemplateIdReferenceExpr into a single, new action ActOnMemberAccessExpr that does the same thing more cleanly (and can keep more source-location information). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85930 91177308-0d34-0410-b5e6-96231b3b80d8

yet another copy of the unqualified-id parsing code. Also, use UnqualifiedId to simplify the Action interface for building id-expressions.

2009-10-13Improve diagnostics when the parser encounters a declarator with anDouglas Gregor
unknown type name, e.g., foo::bar x; when "bar" does not refer to a type in "foo". With this change, the parser now calls into the action to perform diagnostics and can try to recover by substituting in an appropriate type. For example, this allows us to easily diagnose some missing "typename" specifiers, which we now do: test/SemaCXX/unknown-type-name.cpp:29:1: error: missing 'typename' prior to dependent type name 'A<T>::type' A<T>::type A<T>::f() { return type(); } ^~~~~~~~~~ typename Fixes PR3990. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84053 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-22Implement code completion within a function call, triggered after theDouglas Gregor
opening parentheses and after each comma. We gather the set of visible overloaded functions, perform "partial" overloading based on the set of arguments that we have thus far, and return the still-viable results sorted by the likelihood that they will be the best candidate. Most of the changes in this patch are a refactoring of the overloading routines for a function call, since we needed to separate out the notion of building an overload set (common to code-completion and normal semantic analysis) and then what to do with that overload set. As part of this change, I've pushed explicit template arguments into a few more subroutines. There is still much more work to do in this area. Function templates won't be handled well (unless we happen to deduce all of the template arguments before we hit the completion point), nor will overloaded function-call operators or calls to member functions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82549 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-17Initial implementation of a code-completion interface in Clang. InDouglas Gregor
essence, code completion is triggered by a magic "code completion" token produced by the lexer [*], which the parser recognizes at certain points in the grammar. The parser then calls into the Action object with the appropriate CodeCompletionXXX action. Sema implements the CodeCompletionXXX callbacks by performing minimal translation, then forwarding them to a CodeCompletionConsumer subclass, which uses the results of semantic analysis to provide code-completion results. At present, only a single, "printing" code completion consumer is available, for regression testing and debugging. However, the design is meant to permit other code-completion consumers. This initial commit contains two code-completion actions: one for member access, e.g., "x." or "p->", and one for nested-name-specifiers, e.g., "std::". More code-completion actions will follow, along with improved gathering of code-completion results for the various contexts. [*] In the current -code-completion-dump testing/debugging mode, the file is truncated at the completion point and EOF is translated into "code completion". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82166 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

2009-08-25Improve 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

FriendFunctionDecl, and create instances as appropriate.

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.
