2009-12-15Remove isPod() from DenseMapInfo, splitting it out to its ownChris Lattner
isPodLike type trait. This is a generally useful type trait for more than just DenseMap, and we really care about whether something acts like a pod, not whether it really is a pod. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@91421 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-23eliminate the std::ostream forms of the bitcode writing APIs.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79840 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-26Make a major API change to BitstreamReader: split all the readingChris Lattner
state out of the BitstreamReader class into a BitstreamCursor class. Doing this allows the client to have multiple cursors into the same file, each with potentially different live block stacks and abbreviation records. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70157 91177308-0d34-0410-b5e6-96231b3b80d8

2008-02-23Fixed buffer overflow reported by Argiris Kirtzidis.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47517 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-29Use empty() instead of comparing size() with zero.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46514 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-29Remove attribution from file headers, per discussion on llvmdev.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45418 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-17Modified Deserializer::ReadCStr to allow C-strings to be read into aTed Kremenek
std::vector<char> starting from any index in the vector. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45129 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-30Fixed subtle bug in Deserializer::JumpTo when jumping when the block-nestingTed Kremenek
information matching did not exactly match the underlying stream's scoping information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44470 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-14Removed debug #define that was accidentally checked in while debuggingTed Kremenek
the deserializer. Fixed assertion when "stream jumping" in the deserializer to properly function when we have reached the end of the stream. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44124 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-14Added two new overloaded versions of BatchEmitOwnedPtrs andTed Kremenek
BatchReadOwnedPtrs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44105 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
2007-11-10Updated method signature to conform with the typedef in the method prototype.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43982 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
2007-11-09Updated 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
2007-11-07Implemented serialization of signed integers.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43828 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-06Augmented 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
2007-11-06Added 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
2007-11-01Removed 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
2007-10-29Fixed 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
rules. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43369 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-25Added special treatment of serializing NULL pointers.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43357 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
2007-10-23Added preliminary implementation of generic object serialization to bitcode.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43261 91177308-0d34-0410-b5e6-96231b3b80d8
