* Introduce a new node for holding call argumentDuncan Sands2008-03-211-27/+18
| | | | | | | | | | | | | | | | | | flags. This is needed by the new legalize types infrastructure which wants to expand the 64 bit constants previously used to hold the flags on 32 bit machines. There are two functional changes: (1) in LowerArguments, if a parameter has the zext attribute set then that is marked in the flags; before it was being ignored; (2) PPC had some bogus code for handling two word arguments when using the ELF 32 ABI, which was hard to convert because of the bogusness. As suggested by the original author (Nicolas Geoffray), I've disabled it for the moment. Tested with "make check" and the Ada ACATS testsuite. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48640 91177308-0d34-0410-b5e6-96231b3b80d8

* Reimplement the parameter attributes support, phase #1. hilights:Chris Lattner2008-03-121-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | 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
* Clean up my own mess.Evan Cheng2008-03-122-0/+14
| | | | | | | X86 lowering normalize vector 0 to v4i32. However DAGCombine can fold (sub x, x) -> 0 after legalization. It can create a zero vector of a type that's not expected (e.g. v8i16). We don't want to disable the optimization since leaving a (sub x, x) is really bad. Add isel patterns for other types of vector 0 to ensure correctness. It's highly unlikely to happen other than in bugpoint reduced test cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48279 91177308-0d34-0410-b5e6-96231b3b80d8
