    Packed Structure Type +
    +
    +
    Overview:
    +

    The packed structure type is used to represent a collection of data members +together in memory. There is no padding between fields. Further, the alignment +of a packed structure is 1 byte. The elements of a packed structure may +be any type that has a size.

    +

    Structures are accessed using 'load +and 'store' by getting a pointer to a +field with the 'getelementptr' +instruction.

    +
    Syntax:
    +
      < { <type list> } >
    +
    Examples:
    + + + + + +
    + < { int, int, int } >
    + < { float, int (int) * } >
    +     		+ a triple of three int values
    + A pair, where the first element is a float and the second element + is a pointer to a function + that takes an int, returning an int.
