2008-04-23Fixed: <rdar://problem/5881148>Ted Kremenek
Problem: In the recently refactored VisitDeref (which processes dereferences), we were incorrectly skipping the node just generated for the subexpression of the dereference. This was a horrible regression. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@50176 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-23TranslationUnit now owns IdentifierTable, TargetInfo, and Selectors objectsTed Kremenek
when it is constructed via deserialization. This is done by recording a flag indicating that this is the case, and it deletes these objects by getting the references stored in the ASTContext object. This fixes some memory leaks that occurs when we deserialize translation units from bitcode files. The rationale between having TranslationUnit sometimes own these objects and sometimes not is that a TranslationUnit object can be constructed from state generated by the parser (Preprocessor; semantic analyzer, etc.), and thus in these cases won't own the IdentifierTable or Selectors, etc. During deserialization, there is no Preprocessor, so somebody needs to own these objects in order for them to be properly reclaimed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@50149 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-22PathDiagnosticClients now retain ownership of passed PathDiagnostics, requiringTed Kremenek
them to not be stack-allocated. HTMLDiagnostics now batches PathDiagnostics before emitting HTML in its dtor. This is a workaround for a problem when we trampled the Preprocessor state when highlighting macros (sometimes resulting in an assertion failure). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@50102 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-20Two improvements to initializer parsing:Chris Lattner
