2007-11-13Fixed bug with inconsistent serialization/deserialization in matchingTed Kremenek
calls to BatchEmitOwnedPtrs and BatchReadOwnedPtrs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44032 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-12Added versions of ReadPtr that takes an explicit SerializedPtrID. This allowsTed Kremenek
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
2007-11-10Fixed a bug introduced by my last patch. Now we properly clear out the ↵Ted Kremenek
BatchIDVec vector before reusing it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43984 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-10Fixed hack in BatchReadOwnedPtrs to no longer use the array of pointers ↵Ted Kremenek
passed in for deserialization as a temporary location for storing serialized pointer identifiers. The definition of SerializedPtrID will likely change significantly in the future, and the current implementation caused compilation errors on some 64-bit machines. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43983 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-10Added "random access" to the Deserializer to allow a client to jump to anyTed Kremenek
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
2007-11-10Made Deserializer a friend class of BitstreamReader.Ted Kremenek
Moved some of the logic in BitstreamReader::ExitBlock into a utility function BitstreamReader::PopBlockScope. The latter is a private method. It will also be called by Deserializer to manipulate the current "block scope." git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43972 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-09Updated Deserializer class to provide more information about the currentTed Kremenek
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
2007-11-08Added typedef "SerializedPtrID" to represent the pointer handle written to diskTed Kremenek
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
2007-11-08Revised BatchEmitOwnedPtrs to work better with constant pointers.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43861 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-08Revised implementation of BatchReadOwnedPtrs() that deserializes anTed Kremenek
array of pointers to not allocate a second array to contain the pointer ids. Fixed bug in the same member function where deserialized pointers were not being registered with the backpatcher. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43855 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-07Fixed bug where we did not properly serialize owned objects due to a missingTed Kremenek
dereference. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43853 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-07Added version of BatchEmitOwnedPtrs and BatchReadOwnedPtrs that emits/readsTed Kremenek
an array of pointers of the same type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43852 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-07Added methods to batch emit and deserialize owned pointers. This allowsTed Kremenek
to group the pointer IDs together in the bitstream before their referenced contents (which will lend itself to more efficient encoding). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43845 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-07Implemented serialization of signed integers.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43828 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-07Added special version of ReadPtr() that returns a deserialized pointerTed Kremenek
by value. This version prohibits backpatching of pointers, so it useful when a pointee is always known to be deserialized beforehand. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43799 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-06Serializer no longer automatically emits a root-level block in the bitstream.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43784 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-06Augmented ReadPtr and ReadOwnedPtr to control whether or not a pointer is ↵Ted Kremenek
allowed to be backpatched or can be registered with the deserializer to backpatch other pointers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43783 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-06Renamed "Flush()" to "FlushRecord()".Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43772 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-06Added support for processing abbreviations in the Deserializer.Ted Kremenek
Added some #ifdef-controlled messages for debugging backpatching. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43771 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-05Added support in serializer and deserializer to create arbitrary blocks.Ted Kremenek
Added detection of end-of-stream in deserializer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43736 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-05Added default creation of root-level block by bitstream serializer.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43732 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-05Fixed bug where tombstone key and empty key for DenseMap used forTed Kremenek
pointer backpatching in deserializer were improperly created and resulted in an assertion failure. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43721 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-02Added overloaded version of Deserializer::ReadOwnedPtr which allowsTed Kremenek
the target pointer to be passed by reference. This can result in less typing, as the object to be deserialized can be inferred from the argument. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43647 91177308-0d34-0410-b5e6-96231b3b80d8
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
2007-10-31constified several pointer arguments for methods in the Deserializer.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43583 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
2007-10-31Added Serializer::EmitRef to deal with emitting arbitrary references.Ted Kremenek
Modified Serializer::EmitPtr to handle const pointers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43565 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
2007-10-26Fixed bug where default SerializeTrait<>::Materialize would not return the ↵Ted Kremenek
materialized object pointer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43413 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-26Added default implementation of SerializeTrait<> that dispatches toTed Kremenek
calling member functions of the target type to perform type-specific serialization. Added version of ReadPtr that allows passing references to uintptr_t (useful for smart pointers). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43396 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

2007-10-25Created header file to include minimal forward references needed forTed Kremenek
object serialization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43352 91177308-0d34-0410-b5e6-96231b3b80d8
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
