2008-07-28Fold the useful features of alist and alist_node into ilist, andDan Gohman
a new ilist_node class, and remove them. Unlike alist_node, ilist_node doesn't attempt to manage storage itself, so it avoids the associated problems, including being opaque in gdb. Adjust the Recycler class so that it doesn't depend on alist_node. Also, change it to use explicit Size and Align parameters, allowing it to work when the largest-sized node doesn't have the greatest alignment requirement. Change MachineInstr's MachineMemOperand list from a pool-backed alist to a std::list for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54146 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-23Enable first-class aggregates support.Dan Gohman
Remove the GetResultInst instruction. It is still accepted in LLVM assembly and bitcode, where it is now auto-upgraded to ExtractValueInst. Also, remove support for return instructions with multiple values. These are auto-upgraded to use InsertValueInst instructions. The IRBuilder still accepts multiple-value returns, and auto-upgrades them to InsertValueInst instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53941 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-21InsertValue and ExtractValue constant expressions are alwaysDan Gohman
folded. Remove code that handled the case where they aren't folded, and remove bitcode reader/writer support for them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53887 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-09Add a little wrapper header that is put around bc files when emittingChris Lattner
bc files for modules with a target triple that indicates they are for darwin. The reader unconditionally handles this, and the writer could turn this on for more targets if we care. This change has two benefits for darwin: 1) it allows us to encode the cpu type of the file in an easy to read place that doesn't require decoding the bc file. 2) it works around a bug (IMO) in darwin's AR where it is incapable of handling files that are not a multiple of 8 bytes long. BC files are only guaranteed to be multiples of 4 bytes long. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53275 91177308-0d34-0410-b5e6-96231b3b80d8

2007-12-12Implement part of review feedback for address spaces.Christopher Lamb
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44933 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-11Implement address space attribute for LLVM pointer types. Address spaces are Christopher Lamb
regions of memory that have a target specific relationship, as described in the Embedded C Technical Report. This also implements the 2007-12-11-AddressSpaces test, which demonstrates how address space attributes can be used in LLVM IR. In addition, this patch changes the bitcode signature for stores (in a backwards compatible manner), such that the pointer type, rather than the pointee type, is encoded. This permits type information in the pointer (e.g. address space) to be preserved for stores. LangRef updates are forthcoming. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44858 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-10Adding a collector name attribute to Function in the IR. These Gordon Henriksen
methods are new to Function: bool hasCollector() const; const std::string &getCollector() const; void setCollector(const std::string &); void clearCollector(); The assembly representation is as such: define void @f() gc "shadow-stack" { ... The implementation uses an on-the-side table to map Functions to collector names, such that there is no overhead. A StringPool is further used to unique collector names, which are extremely likely to be unique per process. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44769 91177308-0d34-0410-b5e6-96231b3b80d8

2007-11-30Fixed subtle bug in Deserializer::JumpTo when jumping when the block-nestingTed Kremenek

2007-11-17Reverted patch 44199:Ted Kremenek
http://llvm.org/viewvc/llvm-project?rev=44199&view=rev This patch completely broke serialization due to an invariant I assumed but did not hold. The assumed invariant was that all pointer IDs emitted by a call to BatchEmitOwnedPtrs would be consecutive. This is only the case if there has been no forward references to an owned pointer (and hence already registered with the Serializer object). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44203 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-17Changed implementation of Serialize::EmitDiffPtrID andTed Kremenek
Deserialize::ReadDiffPtrID to read and emit bools instead of unsigned integers. This should result in a nice space optimization once we have "auto-abbreviation" generation in place. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44200 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-17Implemented optimization for BatchEmitOwnedPtrs that we only emit one completeTed Kremenek
SerializedPtrID, followed by the *differences* in IDs. The big idea is that most IDs will be just be 1 off from the previous (either that or NULL, which we encode as a difference if 0), so this will greatly reduce the encoding space for extra IDs to just 1 bit per pointer. So far this optimization reduces serialization of Carbon.h by only 1%, but we aren't using any abbreviations now in the Bitcode file to properly take advantage of this optimization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44199 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-15Fixed serious bug in BatchReadOwnedPtrs where in a chain of calls toTed Kremenek
deserialize objects if BatchReadOwnedPtrs was called more than once in the same call chain then the second call would overwrite the SerializedPtrIDs being used by the first call. Solved this problem by making the vector that holds the pointer IDs local to a function call. Now BatchReadOwnedPtrs is reentrant. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44152 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
2007-11-13Renamed serialization method "Materialize" to "Create". This is an API change.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44034 91177308-0d34-0410-b5e6-96231b3b80d8
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

2007-11-07Added 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
