None that I know of.

Symbolization is the default, -bare turns it off.


Another point about -bare and diagnostic tests:  scripted checking for
expected output is a different circumstance than human eyeballs
looking at disassembly.  Scripted checking can break when we make
human friendly aesthetic improvements to the output.  Cleaning up
these character mismatches each time doesn't improve test coverage,
but definitely creates more work.

That said, I'm ready to back off on this idea of per-platform defaults
if it's not acceptable to you and Sean.  If you're asking me to comb
through and alter a large number of diag tests as a precursor to any
symbolizing work, I'll have to sleep on it and let you know.  As we
make incremental output improvements, some tests will break
repeatedly.  Maybe somebody else could take on this part?  -bare at
least solves this problem efficiently, so we can get symbolizing
working.

Cheers guys,
