buildbots question: does stderr output =>FAIL?

[David Tweed]

Hi,

My recent commit still has some tests failing on the ARM buildbots, eg,

http://lab.llvm.org:8011/builders/clang-native-arm-cortex-a9/builds/7967

Trying to run these by hand on a pandaboard llvm-lit is either passing them
or XFAILing them, so I'm a bit at a loss as to what's happening. One thing
that's suddenly occurred to me looking at the stdio buildbot output that the
exit code is actually correct but they're producing output on stderr,
because lli doesn't support one of the options. Maybe this is causing them
to get classified as fails within a buildbot context?

But I don't really know; if anyone has any ideas I'd love to hear them.

Cheers,
Dave
