* Change the PointerType api for creating pointer types. The old functionality ↵Christopher Lamb2007-12-171-1/+1
| | | | | | of PointerType::get() has become PointerType::getUnqual(), which returns a pointer in the generic address space. The new prototype of PointerType::get() requires both a type and an address space. llvm-svn: 45082
* Implement address space attribute for LLVM pointer types. Address spaces are Christopher Lamb2007-12-111-4/+24
| | | | | | | | | | | | | | | | | 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. llvm-svn: 44858

* Adding a collector name attribute to Function in the IR. These Gordon Henriksen2007-12-101-1/+14
| | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 44769

| | | | | | | | | | | | the function type, instead they belong to functions and function calls. This is an updated and slightly corrected version of Reid Spencer's original patch. The only known problem is that auto-upgrading of bitcode files doesn't seem to work properly (see test/Bitcode/AutoUpgradeIntrinsics.ll). Hopefully a bitcode guru (who might that be? :) ) will fix it. llvm-svn: 44359
* In order for parameter attribute uniquing to makeDuncan Sands2007-11-201-6/+4
| | | | | | | | | | | | any sense it is important that ParamAttr::None gets treated the same as not supplying an attribute at all. Rather than stripping ParamAttr::None out of the list of attributes, assert if ParamAttr::None is seen. Fix up the bitcode reader which liked to insert ParamAttr::None all over the place. Patch based on one by Török Edwin. llvm-svn: 44250

* Added versions of ReadPtr that takes an explicit SerializedPtrID. This allowsTed Kremenek2007-11-121-4/+6
| | | | | | | | | | | | 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. llvm-svn: 44021

* Updated Deserializer class to provide more information about the currentTed Kremenek2007-11-091-48/+97
| | | | | | | | | 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). llvm-svn: 43916
* Added typedef "SerializedPtrID" to represent the pointer handle written to diskTed Kremenek2007-11-081-4/+25
| | | | | | | | | | | 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(). llvm-svn: 43903

* Removed ReadVal from SerializeTrait<T>, and also removed it fromTed Kremenek2007-11-011-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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). llvm-svn: 43624
* Rewrote backpatcher. Backpatcher now stores the "has final pointer"Ted Kremenek2007-11-011-21/+19
| | | | | | | | | | | 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. llvm-svn: 43595

* Implemented deserialization of references. References are handledTed Kremenek2007-10-311-1/+13
| | | | | | | | | | | | | 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). llvm-svn: 43570
