[cfe-dev] [LLVMdev] ARM failures

[Galina Kistanova]

Hello guys,

First of all, this builder is configured to send e-mails to the blame list.
I'm the owner of these 2 identical build slaves (which is listed in the
builder's properties :) ).
I keep an eye on this builder. Though, since builds take ~3 hours they
combine quite a lot of changes and the blame lists are long, it takes time
for people to notice and fix issues.

We do need more hardware, indeed.

The build has broken yesterday, then it has been fixed, and broken again.
If I get it right, the revisions in questions for the last break are
r171734 and r171735.

Let me know if anyone needs an access to one of the build slaves to debug.

And it is great that you care!

Thanks

Galina
