ie in the second there is an 'rd'.
I'm referring to some internal documentation for the particular
sparc v9 implementations of UltraSPARC-III and other processors;
it's based on the SPARC Arch Manual v9, and typically includes
all the fixed errata from that (You can download the errata from
sparc.org I think).

Hmmm, no part number on that - very useful! I'm not sure which documntation
that derives from - it looks like a combination of the documents I'm
familiar with.
Go to section 7.11 page 176, in figure 7-2 the last two instruction formats are
exactly the same. I'd like to know if they have been duplicated by a mistake or
if there is a specific reason for duplicate instruction formats, or maybe the
last instruction is supposed to be |op|rd|op3|---| but instead of rd field it
has fcn??
That table for format 3 on 7-176 is the one I was referring to in documentation
quoted above - so I believe it should be 'rd' in the second one.
