Thanks, Stephen.  In particular, do you mean the entries in the
ivl_logic_t enum?  That shouldn't be hard at all, although I don't see
adders in there, and Icarus seems to emit adder cells (ADD8), which
don't seem to be accounted for in that structure...  I was just
wondering what other sorts of stuff like this might crop up before I
release anything.
