  24 The <I>squashtypes</I> program collapses heirarchies of group
  25 types. Each such heirarcy is replaced with a single group
  26 type, under which are all the leaf fields of all the
  27 groups at the appropriate absolute offsets. This can be
  28 useful for making the code more readable and to help backend
  29 C compilers -- some have trouble with very long
  30 heirarchies of group types that get turned into long
  31 heirarchies of structures. Such heirarchies can be created
  32 by various code transformations. For example,
  33 padding between globals can be done by pairwise joining
  34 globals into a new group type with two fields, and repeating
  35 this for many globals leads to a deep heirarchy.
