> Hi @fhahn, I believe this patch breaks the AArch64/SVE buildbots.  You can see the affect on https://lab.llvm.org/buildbot/#/builders/197/builds/2185.  It looks like we were unlucky with the buildbot run that actually contained your patch because this failed for what looks like a temporary CI issue, but all the runs after this point show functional regressions when running LNT.  I've manually checked your commit and the one before yours to confirm this is when things start to fail.

Thanks for the heads-up! Would it be possible to share a preprocessed file that gets miscompiled or an LLVM IR function that shows the issue? Otherwise I won't be able to reproduce/investigate the failure as I do not have accesses to SVE hardware.
