* Now Attributes are divided in three groupsDevang Patel2008-09-261-4/+12
| | | | | | | | | | | | | | - return attributes - inreg, zext and sext - parameter attributes - function attributes - nounwind, readonly, readnone, noreturn Return attributes use 0 as the index. Function attributes use ~0U as the index. This patch requires corresponding changes in llvm-gcc and clang. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56704 91177308-0d34-0410-b5e6-96231b3b80d8

* Enable first-class aggregates support.Dan Gohman2008-07-231-19/+5
| | | | | | | | | | | | | Remove the GetResultInst instruction. It is still accepted in LLVM assembly and bitcode, where it is now auto-upgraded to ExtractValueInst. Also, remove support for return instructions with multiple values. These are auto-upgraded to use InsertValueInst instructions. The IRBuilder still accepts multiple-value returns, and auto-upgrades them to InsertValueInst instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53941 91177308-0d34-0410-b5e6-96231b3b80d8

* Factor code to copy global value attributes likeDuncan Sands2008-05-261-1/+1
| | | | | | | | | | | | | | | | the section or the visibility from one global value to another: copyAttributesFrom. This is particularly useful for duplicating functions: previously this was done by explicitly copying each attribute in turn at each place where a new function was created out of an old one, with the result that obscure attributes were regularly forgotten (like the collector or the section). Hopefully now everything is uniform and nothing is forgotten. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51567 91177308-0d34-0410-b5e6-96231b3b80d8

* Reimplement the parameter attributes support, phase #1. hilights:Chris Lattner2008-03-121-24/+20
| | | | | | | | | | | | | | | | | | | | | | | | | 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
