Detailed Description
A (short) vector of atomic types.
VectorType is used to represent a fixed-size array of elements of an AtomicType. Vectors are similar to arrays in that they support indexing of the elements, but have two key differences. First, all arithmetic and logical operations that are value for the element type can be performed on corresponding VectorTypes (as long as the two VectorTypes have the same size). Second, VectorTypes of uniform elements are laid out in memory aligned to the target's vector size; this allows them to be packed 'horizontally' into vector registers.

| const VectorType * VectorType::GetAsNonConstType | ( | ) | const [virtual] |
Get a non-const version of this type. If it's already not const, then the old Type pointer is returned.

| const Type * VectorType::GetBaseType | ( | ) | const [virtual] |
Returns the basic root type of the given type. For example, for an array or short-vector, this returns the element type. For a struct or atomic type, it returns itself.
