[LLVMdev] Buildslave atom1-buildbot
...Brian,
The Atom1-buildbot buildslave has been failing for a few days but I don't think the problem lies in the LLVM/Clang source. From the logs at http://lab.llvm.org:8011/builders/clang-atom-d2700-ubuntu-rel/builds/13632 (and newer builds):
******************** TEST 'Clang :: Driver/x86_features.s' FAILED ********************
Test has no run line!
********************
I don't see this file in the repository. Could you (or one of your colleagues) take a look?
Thanks

You're not addressing the problem. Your fixing the symptom, which is
wrong to begin with.

This has been discussed to death before and there is no safe subset as
long as this hasn't been resolved:

PAE panic on nv75a / Tecra M2
Attempting to boot xVM dom0 for the first time on a Toshiba Tecra M2
running 75a.
Getting a panic immediately after selecting xVM from the grub menu:
panic[cpu0]/thread=f502c020: Processor does not support PAE
This is a 2000 MHz Pentium-M, which I thought was PAE-capable.

That just happens to not be the case now, but it was for a fair while.

The whole late-microcode loading stuff is crazy already; you're making
