    Packed Type
    +
    Overview:
    +

    A packed type is a simple derived type that represents a vector of elements. Packed types are used when multiple primitive data are operated in parallel using a single instruction (SIMD). A packed type requires a size (number of elements) and an underlying primitive data type. Packed types are considered first class.

    Syntax:

    +  < <# elements> x <elementtype> >
+
    +

    The number of elements is a constant integer value, elementtype may be any integral or floating point type.

    Overview:

    Opaque types are used to represent unknown types in the system. This +corresponds (for example) to the C notion of a foward declared structure type. +In LLVM, opaque types can eventually be resolved to any type (not just a +structure type).
