* Added versions of ReadPtr that takes an explicit SerializedPtrID. This allowsTed Kremenek2007-11-12
| | | | | | | | | | | | | clients of the Deserializer to read the pointer ID before they are ready to deserialize the object (which can mean registering a pointer reference with the backpatcher). Changed some methods that took an argument "SerializedPtrID" to "const SerializedPtrID&" (pass-by-reference). This is to accommodate a future revision of SerializedPtrID where it may be much fatter than an unsigned integer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44021 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | serialized block in the bitstream, including a block in an entirely different nesting than the current block. This is useful for deserializing objects from a bitstream in an order different from the order that they were serialized. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43973 91177308-0d34-0410-b5e6-96231b3b80d8
* Updated Deserializer class to provide more information about the currentTed Kremenek2007-11-09
| | | | | | | | | | block that is being visited in the bitstream. The client can also now skip blocks before reading them, and query the current abbreviation number as seen from the perspective of the Deserializer. This allows the client to be more interactive in the deserialization process (if they so choose). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43916 91177308-0d34-0410-b5e6-96231b3b80d8
* Added typedef "SerializedPtrID" to represent the pointer handle written to diskTed Kremenek2007-11-08
| | | | | | | | | | | | instead of just using "unsigned". This gives us more flexibility in changing the definition of the handle later, and is more self-documenting. Added tracking of block stack in the Deserializer. Now clients can query if they are still within a block using the methods GetCurrentBlockLocation() and FinishedBlock(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43903 91177308-0d34-0410-b5e6-96231b3b80d8

* Removed ReadVal from SerializeTrait<T>, and also removed it fromTed Kremenek2007-11-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Rewrote backpatcher. Backpatcher now stores the "has final pointer"Ted Kremenek2007-11-01
| | | | | | | | | | | | 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

* Implemented deserialization of references. References are handledTed Kremenek2007-10-31
| | | | | | | | | | | | | | 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
