From 0ed844b04ea4387caa4e1cf3dc375d269657536b Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Fri, 4 Apr 2008 06:12:32 +0000 Subject: [PATCH] Introduce ContextDecl, patch by Argiris Kirtzidis! -Added ContextDecl (no TranslationUnitDecl) -ScopedDecl class has a ContextDecl member -FieldDecl class has a ContextDecl member, so that a Field or a ObjCIvar can be traced back to their RecordDecl/ObjCInterfaceDecl easily -FunctionDecl, ObjCMethodDecl, TagDecl, ObjCInterfaceDecl inherit from ContextDecl. With TagDecl as ContextDecl, enum constants have a EnumDecl as their context. -Moved Decl class to a "DeclBase.h" along with ContextDecl class -CurContext is handled by Sema git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49208 91177308-0d34-0410-b5e6-96231b3b80d8 --- Driver/RewriteTest.cpp | 49 +++-- include/clang/AST/Decl.h | 299 ++++++++---------------------- include/clang/AST/DeclBase.h | 330 ++++++++++++++++++++++++++++++++++ include/clang/AST/DeclObjC.h | 43 +++-- lib/AST/ASTContext.cpp | 9 +- lib/AST/Decl.cpp | 97 +++++----- lib/AST/DeclObjC.cpp | 42 +++-- lib/AST/DeclSerialization.cpp | 24 +-- lib/Sema/Sema.cpp | 21 ++- lib/Sema/Sema.h | 9 +- lib/Sema/SemaDecl.cpp | 46 +++-- lib/Sema/SemaDeclObjC.cpp | 35 ++-- 12 files changed, 635 insertions(+), 369 deletions(-) create mode 100644 include/clang/AST/DeclBase.h diff --git a/Driver/RewriteTest.cpp b/Driver/RewriteTest.cpp index c564576248..b7c65a5e2b 100644 --- a/Driver/RewriteTest.cpp +++ b/Driver/RewriteTest.cpp @@ -822,7 +822,7 @@ Stmt *RewriteTest::RewriteObjCIvarRefExpr(ObjCIvarRefExpr *IV) { std::string RecName = clsDeclared->getIdentifier()->getName();
