I've been testing cross-platform software for over 30 years.  One thing
I would never do is use an emulator (ANY emulator) for testing (except
maybe for early in the development cycle).

No emulator is perfect, and real hardware can operate slightly
differently than emulated hardware.  Even things like small timing
differences can cause problems - I've seen code which works on a system
running at one speed but not a faster (or slower) one.

Your SPARC may be noisy - but it's still the best platform for testing
SPARC software.
