How can we test the performance on SPARC between programs built with
these compilers?

Have you some references about this issue? Is there a benchmark used to
substantiate it?

In what you propose, we still use g++ on the very platform which has a
performance issue and with SS on the platform where g++ doesn't. Why not
go with g++ on all platforms in this case?  Maintenance wise is less
complex, isn't it?
