From 2d74de96325e44dd46713c5dc29dba48339ad6bd Mon Sep 17 00:00:00 2001 From: John McCall Date: Tue, 1 Dec 2009 22:10:20 +0000 Subject: Rework how we support C++ implicit member accesses. If we can resolve an 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. llvm-svn: 90266 --- clang/lib/Sema/Sema.h | 17 +++++++++++++---- 1 file changed, 13 insertions(+), 4 deletions(-) (limited to 'clang/lib/Sema/Sema.h') diff --git a/clang/lib/Sema/Sema.h b/clang/lib/Sema/Sema.h index f961406e3e5..4b437995f15 100644 --- a/clang/lib/Sema/Sema.h +++ b/clang/lib/Sema/Sema.h @@ -1023,7 +1023,7 @@ public: SourceLocation RLoc, ExprArg Base,ExprArg Idx); - ExprResult + OwningExprResult BuildCallToMemberFunction(Scope *S, Expr *MemExpr, SourceLocation LParenLoc, Expr **Args, unsigned NumArgs, SourceLocation *CommaLocs, @@ -1451,9 +1451,10 @@ public: FieldDecl *Field, Expr *BaseObjectExpr = 0, SourceLocation OpLoc = SourceLocation()); - OwningExprResult BuildImplicitMemberReferenceExpr(const CXXScopeSpec &SS, - LookupResult &R, - const TemplateArgumentListInfo *TemplateArgs); + OwningExprResult BuildImplicitMemberExpr(const CXXScopeSpec &SS, + LookupResult &R, + const TemplateArgumentListInfo *TemplateArgs, + bool IsDefiniteInstance); bool UseArgumentDependentLookup(const CXXScopeSpec &SS, const LookupResult &R, bool HasTrailingLParen); @@ -1525,6 +1526,7 @@ public: SourceLocation RLoc); OwningExprResult BuildMemberReferenceExpr(ExprArg Base, + QualType BaseType, SourceLocation OpLoc, bool IsArrow, const CXXScopeSpec &SS, @@ -1534,6 +1536,7 @@ public: const TemplateArgumentListInfo *TemplateArgs); OwningExprResult BuildMemberReferenceExpr(ExprArg Base, + QualType BaseType, SourceLocation OpLoc, bool IsArrow, const CXXScopeSpec &SS, LookupResult &R, @@ -1551,6 +1554,7 @@ public: const LookupResult &R); OwningExprResult ActOnDependentMemberExpr(ExprArg Base, + QualType BaseType, bool IsArrow, SourceLocation OpLoc, const CXXScopeSpec &SS, @@ -1592,6 +1596,11 @@ public: MultiExprArg Args, SourceLocation *CommaLocs, SourceLocation RParenLoc); + OwningExprResult BuildResolvedCallExpr(Expr *Fn, + NamedDecl *NDecl, + SourceLocation LParenLoc, + Expr **Args, unsigned NumArgs, + SourceLocation RParenLoc); virtual OwningExprResult ActOnCastExpr(Scope *S, SourceLocation LParenLoc, TypeTy *Ty, SourceLocation RParenLoc, -- cgit v1.2.3
