2009-12-03Introduce the notion of literal types, as specified in C++0x.Sebastian Redl
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90361 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-01Rework how we support C++ implicit member accesses. If we can resolve anJohn McCall
implicit member access to a specific declaration, go ahead and create it as a DeclRefExpr or a MemberExpr (with implicit CXXThisExpr base) as appropriate. Otherwise, create an UnresolvedMemberExpr or DependentScopeMemberExpr with a null base expression. By representing implicit accesses directly in the AST, we get the ability to correctly delay the decision about whether it's actually an instance member access or not until resolution is complete. This permits us to correctly avoid diagnosing the 'problem' of 'MyType::foo()' where the relationship to the type isn't really known until instantiation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90266 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-30Eliminate the use of OverloadedFunctionDecl in member expressions.John McCall
Create a new UnresolvedMemberExpr for these lookups. Assorted hackery around qualified member expressions; this will all go away when we implement the correct (i.e. extremely delayed) implicit-member semantics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90161 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-25Eliminate CXXConditionDeclExpr with extreme prejudice.Douglas Gregor
All statements that involve conditions can now hold on to a separate condition declaration (a VarDecl), and will use a DeclRefExpr referring to that VarDecl for the condition expression. ForStmts now have such a VarDecl (I'd missed those in previous commits). Also, since this change reworks the Action interface for if/while/switch/for, use FullExprArg for the full expressions in those expressions, to ensure that we're emitting Note that we are (still) not generating the right cleanups for condition variables in for statements. That will be a follow-on commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89817 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-24Rip out TemplateIdRefExpr and make UnresolvedLookupExpr and John McCall
DependentScopeDeclRefExpr support storing templateids. Unite the common code paths between ActOnDeclarationNameExpr and ActOnTemplateIdExpr. This gets us to a point where we don't need to store function templates in the AST using TemplateNames, which is critical to ripping out OverloadedFunction. Also resolves a few FIXMEs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89785 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-23Encapsulate "an array of TemplateArgumentLocs and two angle bracket ↵John McCall
locations" into a new class. Use it pervasively throughout Sema. My fingers hurt. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89638 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-21"Incremental" progress on using expressions, by which I mean totally rippingJohn McCall
into pretty much everything about overload resolution in order to wean BuildDeclarationNameExpr off LookupResult::getAsSingleDecl(). Replace UnresolvedFunctionNameExpr with UnresolvedLookupExpr, which generalizes the idea of a non-member lookup that we haven't totally resolved yet, whether by overloading, argument-dependent lookup, or (eventually) the presence of a function template in the lookup results. Incidentally fixes a problem with argument-dependent lookup where we were still performing ADL even when the lookup results contained something from a block scope. Incidentally improves a diagnostic when using an ObjC ivar from a class method. This just fell out from rewriting BuildDeclarationNameExpr's interaction with lookup, and I'm too apathetic to break it out. The only remaining uses of OverloadedFunctionDecl that I know of are in TemplateName and MemberExpr. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89544 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-19Draw a brighter line between "unresolved" expressions, where we have done theJohn McCall
appropriate lookup and simply can't resolve the referrent yet, and "dependent scope" expressions, where we can't do the lookup yet because the entity we need to look into is a dependent type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89402 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-29Track source information for template arguments and template specializationJohn McCall
types. Preserve it through template instantiation. Preserve it through PCH, although TSTs themselves aren't serializable, so that's pretty much meaningless. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85500 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-09Improve handling of initialization by constructor, by ensuring thatDouglas Gregor
such initializations properly convert constructor arguments and fill in default arguments where necessary. This also makes the ownership model more clear. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@81394 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-09Initial stab at implement dependent member references to memberDouglas Gregor
templates, e.g., x.template get<T> We can now parse these, represent them within an UnresolvedMemberExpr expression, then instantiate that expression node in simple cases.

2009-07-29Change uses of:Ted Kremenek
Type::getAsReferenceType() -> Type::getAs<ReferenceType>() Type::getAsRecordType() -> Type::getAs<RecordType>() Type::getAsPointerType() -> Type::getAs<PointerType>() Type::getAsBlockPointerType() -> Type::getAs<BlockPointerType>() Type::getAsLValueReferenceType() -> Type::getAs<LValueReferenceType>() Type::getAsRValueReferenceType() -> Type::getAs<RValueReferenceType>() Type::getAsMemberPointerType() -> Type::getAs<MemberPointerType>() Type::getAsReferenceType() -> Type::getAs<ReferenceType>() Type::getAsTagType() -> Type::getAs<TagType>() And remove Type::getAsReferenceType(), etc. This change is similar to one I made a couple weeks ago, but that was partly reverted pending some additional design discussion. With Doug's pending smart pointer changes for Types, it seemed natural to take this approach. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77510 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-23This patch fixes the implementations of the __has_trivial_destructorDouglas Gregor

2009-07-17Per offline discussion with Steve Naroff, add back Type::getAsXXXType() methodsTed Kremenek
until Doug Gregor's Type smart pointer code lands (or more discussion occurs). These methods just call the new Type::getAs<XXX> methods, so we still have reduced implementation redundancy. Having explicit getAsXXXType() methods makes it easier to set breakpoints in the debugger. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76193 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-22Representation of and template instantiation for memberDouglas Gregor
expressions. This change introduces another AST node, CXXUnresolvedMemberExpr, that captures member references (x->m, x.m) when the base of the expression (the "x") is type-dependent, and we therefore cannot resolve the member reference yet. Note that our parsing of member references for C++ is still quite poor, e.g., we don't handle x->Base::m or x->operator int. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72281 91177308-0d34-0410-b5e6-96231b3b80d8

describe the construction of a value of a given type using function syntax, e.g., T(a1, a2, ..., aN) when the type or any of its arguments are type-dependent. In this case, we don't know what kind of type-construction this will be: it might construct a temporary of type 'T' (which might be a class or non-class type) or might perform a conversion to type 'T'. Also, implement printing of and template instantiation for this new expression type. Due to the change in Sema::ActOnCXXTypeConstructExpr, our existing tests cover template instantiation of this new expression node. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72176 91177308-0d34-0410-b5e6-96231b3b80d8
