2008-03-12Reimplement the parameter attributes support, phase #1. hilights:Chris Lattner
1. There is now a "PAListPtr" class, which is a smart pointer around the underlying uniqued parameter attribute list object, and manages its refcount. It is now impossible to mess up the refcount. 2. PAListPtr is now the main interface to the underlying object, and the underlying object is now completely opaque. 3. Implementation details like SmallVector and FoldingSet are now no longer part of the interface. 4. You can create a PAListPtr with an arbitrary sequence of ParamAttrsWithIndex's, no need to make a SmallVector of a specific size (you can just use an array or scalar or vector if you wish). 5. All the client code that had to check for a null pointer before dereferencing the pointer is simplified to just access the PAListPtr directly. 6. The interfaces for adding attrs to a list and removing them is a bit simpler. Phase #2 will rename some stuff (e.g. PAListPtr) and do other less invasive changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48289 91177308-0d34-0410-b5e6-96231b3b80d8

2007-12-17Change the PointerType api for creating pointer types. The old functionality ↵Christopher Lamb
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45082 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
2007-12-11Adding Ocaml bindings for the bitreader as requested by SarahGordon Henriksen
Thompson. Usage should be something like this: open Llvm open Llvm_bitreader match read_bitcode_file fn with | Bitreader_failure msg -> prerr_endline msg | Bitreader_success m -> ...; dispose_module m Compile with: ocamlc llvm.cma llvm_bitreader.cma ocamlopt llvm.cmxa llvm_bitreader.cmxa git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44824 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

2007-11-27Fix PR1146: parameter attributes are longer part ofDuncan Sands
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44359 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-20In order for parameter attribute uniquing to makeDuncan Sands
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44250 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

2007-11-12Added 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

2007-11-10Added "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
