From: Douglas Gregor Date: Tue, 20 Jan 2009 01:17:11 +0000 (+0000) Subject: Remove ScopedDecl, collapsing all of its functionality into Decl, so X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=4afa39deaa245592977136d367251ee2c173dd8d;p=clang Remove ScopedDecl, collapsing all of its functionality into Decl, so that every declaration lives inside a DeclContext. Moved several things that don't have names but were ScopedDecls (and, therefore, NamedDecls) to inherit from Decl rather than NamedDecl, including ObjCImplementationDecl and LinkageSpecDecl. Now, we don't store empty DeclarationNames for these things, nor do we try to insert them into DeclContext's lookup structure. The serialization tests are temporarily disabled. We'll re-enable them once we've sorted out the remaining ownership/serialiazation issues between DeclContexts and TranslationUnion, DeclGroups, etc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62562 91177308-0d34-0410-b5e6-96231b3b80d8 --- diff --git a/Driver/ASTConsumers.cpp b/Driver/ASTConsumers.cpp index 6729746573..6f66307c4b 100644 --- a/Driver/ASTConsumers.cpp +++ b/Driver/ASTConsumers.cpp @@ -122,8 +122,8 @@ void DeclPrinter:: PrintDecl(Decl *D) { Out << "asm(";
