llvm with tablegen backend for capstone disassembler

Chris Lattner 8a923e7c28 Reimplement the parameter attributes support, phase #1. hilights: ... 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. llvm-svn: 48289		2008-03-12 17:45:29 +00:00
clang	Use the "used" attribute. Without it, g++ removes all the meta-data:-( This doesn't happen when compiling straight C code.	2008-03-12 17:18:30 +00:00
