* Reimplement the parameter attributes support, phase #1. hilights:Chris Lattner2008-03-122-21/+10
| | | | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

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
