* Initial soft-float support for LegalizeTypes. I rewroteDuncan Sands2008-03-126-34/+248
| | | | | | | | | | | | | | | | | | | | | | the fcopysign expansion from LegalizeDAG to get rid of what seems to be a bug: the use of sign extension means that when copying the sign bit from an f32 to an f64, the upper 32 bits of the f64 (now an i64) are set, not just the top bit... I also generalized it to work for any sized floating point types, and removed the bogosity: SDOperand Mask1 = (SrcVT == MVT::f64) ? DAG.getConstantFP(BitsToDouble(1ULL << 63), SrcVT) : DAG.getConstantFP(BitsToFloat(1U << 31), SrcVT); Mask1 = DAG.getNode(ISD::BIT_CONVERT, SrcNVT, Mask1); (here SrcNVT is an integer with the same size as SrcVT). As far as I can see this takes a 1 << 63, converts to a double, converts that to a floating point constant then converts that to an integer constant, ending up with... 1 << 63 as an integer constant! So I just generate this integer constant directly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48305 91177308-0d34-0410-b5e6-96231b3b80d8

* Reimplement the parameter attributes support, phase #1. hilights:Chris Lattner2008-03-1223-1005/+857
| | | | | | | | | | | | | | | | | | | | | | | | | 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
