<br>
Could someone please revert r275678 (LLVM) and 275679 (Clang) for me? I can't do this myself right now. If someone with this configuration could bugpoint these regressions test failures (which I imagine should be possible given that this is a stage-2 LTO build), that would certainly be appreciated.<br>
<br>
Interestingly, this was the only builder that complained. Is this the only self-host w/ LTO builder that we have? Also, what do I click on in Jenkins (or elsewhere) to see the full build parameters, system information, etc.?<br>
<br>
Thanks again,<br>
Hal<br>
