| static VectorType* llvm::VectorType::getExtendedElementVectorType | ( | VectorType * | VTy | ) | [inline, static] |
VectorType::getExtendedElementVectorType - This static method is like getInteger except that the element types are twice as wide as the elements in the input type.

| static VectorType* llvm::VectorType::getInteger | ( | VectorType * | VTy | ) | [inline, static] |
VectorType::getInteger - This static method gets a VectorType with the same number of elements as the input type, and the element type is an integer type of the same width as the input element type.
