2006-04-02Implement the Expand action for binary vector operations to break the binopChris Lattner
into elements and operate on each piece. This allows generic vector integer multiplies to work on PPC, though the generated code is horrible. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27347 91177308-0d34-0410-b5e6-96231b3b80d8
2006-04-02Intrinsics that just load from memory can be treated like loads: they don'tChris Lattner
have to serialize against each other. This allows us to schedule lvx's across each other, for example. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27346 91177308-0d34-0410-b5e6-96231b3b80d8

2006-03-31TargetData.cpp::getTypeInfo() was returning alignment of element type as theEvan Cheng
alignment of a packed type. This is obviously wrong. Added a workaround that returns the size of the packed type as its alignment.
