squashtypes - collapse heirarchies of group types
squashtypes infile outfile { infile outfile } *
The squashtypes program collapses heirarchies of group types. Each such heirarcy is replaced with a single group type, under which are all the leaf fields of all the groups at the appropriate absolute offsets. This can be useful for making the code more readable and to help back-end C compilers -- some have trouble with very long heirarchies of group types that get turned into long heirarchies of structures. Such heirarchies can be created by various code transformations. For example, padding between globals can be done by pairwise joining globals into a new group type with two fields, and repeating this for many globals leads to a deep heirarchy.
This program was written by Chris Wilson.
