But 'cond' would be an unflattened tree expression.  I'm trying to avoid 
that.

Yeah, that would mean adding 5 more tree codes, though.  Unless we gave 
up and invented a new set of subcodes exclusively for gimple.  That 
seems like a waste, since tree.def neatly defines all the subcodes we 
want already.


Thanks.  Diego.
