I'm currently working on syncing the toplevel files between gcc and
src, so at least please wait until I finish that, or at least make
sure both sides get updated.  Otherwise, simply rearranging the
patterns so that the more specific ones come first makes sense;
perhaps put all the chip-independent patterns at the end?
