</span>Hi David,<br>
<br>
I haven't bisected yet, but it's likely that this commit is the one<br>
responsible for this failure:<br>
<br>
<a href="https://urldefense.proofpoint.com/v2/url?u=http-3A__lab.llvm.org-3A8011_builders_clang-2Dx86-5F64-2Dlinux-2Dselfhost-2Dabi-2Dtest_builds_5543&d=AwMFaQ&c=8hUWFZcy2Z-Za5rBPlktOQ&r=mQ4LZ2PUj9hpadE3cDHZnIdEwhEBrbAstXeMaFoB9tg&m=YZNWTgTNx90i_HoLkDDoxZqYH1tuVAkAsPa6CwZNL3A&s=IzngJkhFJABhxc6ScJjqFiBW-5EBC9WjMZ0gAU7Z9Ec&e=" target="_blank">http://lab.llvm.org:8011/builders/clang-x86_64-linux-selfhost-abi-test/builds/5543</a><br>
<br>
And all self-hosting + test-suite failures in ARM. :)<br>
<br>
The effect is the same, times out, gets killed.<br>
<br>
cheers,<br>
