2007-11-01Removed ReadVal from SerializeTrait<T>, and also removed it fromTed Kremenek
Deserializer. There were issues with Visual C++ barfing when instantiating SerializeTrait<T> when "T" was an abstract class AND SerializeTrait<T>::ReadVal was *never* called: template <typename T> struct SerializeTrait { <SNIP> static inline T ReadVal(Deserializer& D) { T::ReadVal(D); } <SNIP> }; Visual C++ would complain about "T" being an abstract class, even though ReadVal was never instantiated (although one of the other member functions were). Removing this from the trait is not a big deal. It was used hardly ever, and users who want "read-by-value" deserialization can simply call the appropriate methods directly instead of relying on trait-based-dispatch. The trait dispatch for serialization/deserialization is simply sugar in many cases (like this one). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43624 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-01Rewrote backpatcher. Backpatcher now stores the "has final pointer"Ted Kremenek
flag in the **key** of the backpatch map, as opposed to the mapped value which contains either the final pointer, or a pointer to a chain of pointers that need to be backpatched. The bit flag was moved to the key because we were erroneously assuming that the backpatched pointers would be at an alignment of >= 2 bytes, which obviously doesn't work for character strings. Now we just steal the bit from the key. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43595 91177308-0d34-0410-b5e6-96231b3b80d8

2007-10-31Implemented deserialization of references. References are handledTed Kremenek
just like pointers, except that they cannot be backpatched. This means that references are essentially non-owning pointers where the referred object must be deserialized prior to the reference being deserialized. Because of the nature of references, this ordering of objects is always possible. Fixed a bug in backpatching code (returning the backpatched pointer would accidentally include a bit flag). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43570 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-29Fixed warning concerning implicit conversion from a NULL pointerTed Kremenek
constant to an unsigned int. We now just directly assign the literal 0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43459 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-28Fixed assertion in Deserializer::~Deserializer that checks forTed Kremenek
pointers that were not backpatched (previously checked the wrong invariant). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43425 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-28Updated backpatching logic during object deserialization to performTed Kremenek
eager backpatching instead of waithing until all objects have been deserialized. This allows us to reduce the memory footprint needed for backpatching. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43422 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-25Updated backpatching during object deserialization to support "smart"Ted Kremenek
pointers that employ unused bits in a pointer to store extra data. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43373 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-25Disambiguated variable name to comply with VC++'s archaic variable scoping ↵Hartmut Kaiser

2007-10-25Added special treatment of serializing NULL pointers.Ted Kremenek

2007-10-25Implemented prototype serialization of pointers, including supportTed Kremenek
for backpatching. Added Deserialize::ReadVal. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43319 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-24Split Serialization.h into separate headers: Serialize.h andTed Kremenek
Deserialize.h Serialization.h now includes trait speciailizations for unsigned long, etc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43307 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-23Added preliminary implementation of generic object serialization to bitcode.Ted Kremenek
