Hi Duncan,

There are two issues:

1. The LTO bug we found by running Livermore Loops on test-suite. I'm still
trying to isolate this and will report as soon as I get a smaller test
case. (I sent a tarball earlier to the list on how to reproduce it). Bugs
like these will not be caught any more with the standard LNT tests, true,
but there's also point 2 below...

2. Buildbots with multiple test builders, confusing and generating too much
noise. LNT is not testing LTO at the moment, but David said there someone
working on it right now. So, the way to go would be to have LNT on all
buildbots (in the long run) testing with and without LTO (and possibly
other variations), so we can have a coherent story and an easy way to
reproduce errors locally.


To test you need to set up your own build master.  It's not that hard.

That's a good point. I'll do that.
