* Reimplement the parameter attributes support, phase #1. hilights:Chris Lattner2008-03-121-33/+17
| | | | | | | | | | | | | | | | | | | | | | | | | 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

* Implement address space attribute for LLVM pointer types. Address spaces are Christopher Lamb2007-12-111-2/+9
| | | | | | | | | | | | | | | | | | 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
* Adding a collector name attribute to Function in the IR. These Gordon Henriksen2007-12-101-0/+2
| | | | | | | | | | | | | | | | | | | | | 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

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

Use APFloat functions for constant folding arithmetic and comparisons.
