I would suggest re-naming "rmbdd()". I _assume_ that "dd" stands for "data
dependent", but quite frankly, "rmbdd" looks like the standard IBM "we
lost every vowel ever invented" kind of assembly lanaguage to me.
I'm sure that having programmed PPC assembly language, you find it very
natural (IBM motto: "We found five vowels hiding in a corner, and we used
them _all_ for the 'eieio' instruction so that we wouldn't have to use
them anywhere else").
