2007-11-20Added another test case for the Dead Stores checker that tests thatTed Kremenek
block-level expressions are evaluated the same as regular expressions. Test case provided by Nuno Lopes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44247 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-20Updated CFGStmtVisitor and CFGRecStmtVisitor to have a notion ofTed Kremenek
"block-expressions" when visiting arbitrary expressions (via calls to "Visit()"). This results in a refactoring where a dataflow analysis no longer needs to always special case when handling block-expressions versus non-block expressions. Updated LiveVariables and UninitializedValues to conform to the slightly altered interface of these visitor classes. Thanks to Nuno Lopes for providing a test case that illustrated some fundamental problems in the current design of the CFGXXXStmtVisitor classes and how they were used. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44246 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-19Removed PersistentMap. It is now superseded in every way by the ImmutableMapTed Kremenek

2007-11-19Added test case for dead stores checker (live variables analysis) that testsTed Kremenek
for correct propagation/update of liveness information within subexpressions of Block-Level expressions. Test case provided by Nuno Lopes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44225 91177308-0d34-0410-b5e6-96231b3b80d8

2007-11-18Fixed bug in WalkaST_VisitDeclSubExprs where we failed to properly check ifTed Kremenek
the StmtIterator referring to the initializers of a chain of Decls was equal to the "end" iterator. The particular bug manifested when an iterator was created on a chain of decls with no initializers. Thanks to Nuno Lopes for reporting this bug and providing a patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44220 91177308-0d34-0410-b5e6-96231b3b80d8

2007-11-16Added assertion in serialization of DeclRefExprs. DeclRefExprs can onlyTed Kremenek
own the decl they reference if it is a FunctionDecl. Note that his ownership property is still considered a hack, and should be fixed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44192 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-16Fixed bug in the serialization of FunctionDecls. We would incorrectlyTed Kremenek
query for the number of parameters for FunctionDecls that had type FunctionTypeNoProto. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44191 91177308-0d34-0410-b5e6-96231b3b80d8

2007-11-15Added hack when serializing DeclRefExprs. This should probably be fixed.Ted Kremenek
Some FunctionDecls do not appear at the top-level or are owned by a DeclStmt. In calls to implicitly defined functions, a FunctionDecl is created, but only the DeclRefExprs reference them. Since an implicitly defined function may be called multiple times, there is no clear ownership model for such objects. Temporary solution: when serializing out DeclRefExprs, emit an ownership bit for the Decl. This bit is determined by querying the serializer to see if the Decl has already been serialized. If it hasn't, emit the Decl as an owned pointer. I repeat: this is a hack. This should be fixed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44176 91177308-0d34-0410-b5e6-96231b3b80d8

"default constructed" an APSInt. Fixed another bug in the same method where we did not allow the NextDeclarator to be NULL. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44147 91177308-0d34-0410-b5e6-96231b3b80d8

qualifiers as part of the pointer address. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44146 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-14Always generate a typedef for @class. The typedef removal logic that I'm ↵Steve Naroff
removing only made sense when we were operating on preprocess files without typedef guards. Now that we have guards, it is incorrect to ever remove one (since it may increase the likelihood that the rewritten header can't be included stand alone). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44145 91177308-0d34-0410-b5e6-96231b3b80d8

2007-11-14Added QualType::ReadBackpatch to allow QualType initialization withTed Kremenek
backpatching. This original was available, but then we removed it. It is back again to help with deserialization of FieldDecls. Because FieldDecls are currently owned by RecordDecls, which are owned by a TagType, the type of the FieldDecl may not be deserialized prior to deserializing the FieldDecl. Thus backpatching solves the problem of constructing a FieldDecl that references a type that has not yet been deserialized. Simplified serialization of TagType to not require passing in the SerializedPtrID. Registration of the materialized type object is done after the CreateImpl method returns (as with other types). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44143 91177308-0d34-0410-b5e6-96231b3b80d8
