Oh!  That makes a bit more sense, then.

Is this documented anywhere?  I just went through every place where the
string "SZ" occurs in pdftotext output on that PDF and none of them
mention this as far as I can see.  (Where did you learn it, for
example?)

Well, writing it out for every affected instruction, maybe.  Mentioning
it on pages 19 and 123 (which describe the FPCSR) would have helped
greatly, especially if the affected instruction pages cross-referenced
that (they have so much other boilerplate I have trouble imagining this
would have been all that onerous).

I hasten to note that it's Hitachi these get me upset at, not you!
What I say to you is more like, thank you very much for clearing up my
misunderstanding!
