2009-11-21Added rudimentary C++0x attribute support.Sean Hunt
The following attributes are currently supported in C++0x attribute lists (and in GNU ones as well): - align() - semantics believed to be conformant to n3000, except for redeclarations and what entities it may apply to - final - semantics believed to be conformant to CWG issue 817's proposed wording, except for redeclarations - noreturn - semantics believed to be conformant to n3000, except for redeclarations - carries_dependency - currently ignored (this is an optimization hint) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89543 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-10Improve parsing of template arguments to lay the foundation forDouglas Gregor
handling template template parameters properly. This refactoring: - Parses template template arguments as id-expressions, representing the result of the parse as a template name (Action::TemplateTy) rather than as an expression (lame!). - Represents all parsed template arguments via a new parser-specific type, ParsedTemplateArgument, which stores the kind of template argument (type, non-type, template) along with all of the source information about the template argument. This replaces an ad hoc set of 3 vectors (one for a void*, which was either a type or an expression; one for a bit telling whether the first was a type or an expression; and one for a single source location pointing at the template argument). - Moves TemplateIdAnnotation into the new Parse/Template.h. It never belonged in the Basic library anyway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86708 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-04Change our basic strategy for avoiding deprecation warnings when the decl useJohn McCall
appears in a deprecated context. In the new strategy, we emit the warnings as usual unless we're currently parsing a declaration, where "declaration" is restricted to mean a decl group or a few special cases in Objective C. If we *are* parsing a declaration, we queue up the deprecation warnings until the declaration has been completely parsed, and then emit them only if the decl is not deprecated. We also standardize the bookkeeping for deprecation so as to avoid special cases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85998 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-03CFieldCallback doesn't need to create an ExtensionRAIIObject: it's actuallyJohn McCall

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
2009-11-03Reorganize the parsing of decl groups / function definitions so thatJohn McCall
declarators are parsed primarily within a single function (at least for these cases). Remove some excess diagnostics arising during parse failures. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85924 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-03Switch ParseStructDeclaration to a callback-based API. This will makeJohn McCall
it easier to track within Sema whether the parser is parsing a declaration. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85855 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-03Introduce a new class, UnqualifiedId, that provides a parsedDouglas Gregor
representation of a C++ unqualified-id, along with a single parsing function (Parser::ParseUnqualifiedId) that will parse all of the various forms of unqualified-id in C++. Replace the representation of the declarator name in Declarator with the new UnqualifiedId class, simplifying declarator-id parsing considerably and providing more source-location information to Sema. In the future, I hope to migrate all of the other unqualified-id-parsing code over to this single representation, then begin to merge actions that are currently only different because we didn't have a unqualified notion of the name in the parser. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85851 91177308-0d34-0410-b5e6-96231b3b80d8
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

2009-09-25Declarators can now properly represent template-ids, e.g., forDouglas Gregor
template void f<int>(int); ~~~~~~ Previously, we silently dropped the template arguments. With this change, we now use the template arguments (when available) as the explicitly-specified template arguments used to aid template argument deduction for explicit template instantiations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82806 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

2009-09-02Rewrite 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
2009-08-26When we know that we are parsing a class-name, implicitly construct aDouglas Gregor
TypenameType if getTypeName is looking at a member of an unknown specialization. This allows us to properly parse class templates that derived from type that could only otherwise be described by a typename type, e.g., template<class T> struct X {}; template<typename T> struct Y : public X<T>::X { }; Fixes PR4381. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80123 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-26Fix bug in __extension__ handling for declarations, from AbramoDouglas Gregor
Bagnara with a fix from Enea Zaffanella! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80094 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
