From ea0c6fb7c52df99349066ff1aed58e4dfc4c7289 Mon Sep 17 00:00:00 2001 From: Ted Kremenek Date: Wed, 14 Nov 2007 00:03:20 +0000 Subject: [PATCH] Modified ASTContext::getTagDeclType() to accept a NULL pointer for the passed in TagDecl*. This allows the deserializer to use ASTContext to create the TagTypes. Deserialize TagTypes then rely on pointer-backpatching to resolve the decls. This may not be the interface that we want, but as the implementation of TagTypes will potentially change significantly in the future, I'm leaving this for now. An appropriate FIXME is in place. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44089 91177308-0d34-0410-b5e6-96231b3b80d8 --- AST/ASTContext.cpp | 15 +++++++++++---- 1 file changed, 11 insertions(+), 4 deletions(-) diff --git a/AST/ASTContext.cpp b/AST/ASTContext.cpp index b844adf431..9d597bcc43 100644 --- a/AST/ASTContext.cpp +++ b/AST/ASTContext.cpp @@ -717,12 +717,19 @@ QualType ASTContext::getTypeOfType(QualType tofType) { /// getTagDeclType - Return the unique reference to the type for the /// specified TagDecl (struct/union/class/enum) decl.
