More interesting than you can imagine :-) When you reverse engineer "normal" code, you know the CPU can handle integers of X, 2X, 4X bit widths, you know it wants things aligned this way or that way etc. The R1000 is bit addressed, and integers can be any width from 1 to 64 bits, structures can be "variant" (See: Ada) so reverse engineering the storage layout is ... not an accomplished feat yet. Since the primary task for the R1000 was Ada program development, and since there were a standardized semantic representation of Ada programs ("DIANA"), one of the fundamental hardware/microcode data-types is "DianaTree", which is, I think a pretty generic CS tree of some kind. These "DianaTree" types seem to also have been used for other stuff, like directories in the object store etc.
