While I haven't worked on SUIF at all in years, the project I was
working on involved running some passes that were only available in
SUIF 1 (and not the final released version of SUIF 1 either) and a
custom MachSUIF backend. There's a SUIF 1-to-2 converter distributed,
IIRC, with SUIF 2, depending specifically on that final version. So
we built:


(1) Build SUIF 1-old.
(2) Build SUIF 1-final.
(3) Build SUIF 2, including MachSUIF, against SUIF 1-final.


And then ran:


(1) SUIF 1-old frontend.
(2) Other SUIF 1-old passes.
(3) SUIF 1-final to SUIF 2 converter.
(4) SUIF 2 to MachSUIF converter.
(5) MachSUIF passes.


This seemed to work pretty reliably...but as I said, this was five
years ago now.
