Progress (short week, 3 days): * UM-2 [QEMU upstream maintainership] - more FEAT_NMI patchset review: done with the physical interrupt parts, haven't looked at the virtual interrupt parts yet - usual release related effort - investigated and fixed a bug where we were taking HSTR traps to the wrong EL - noticed a minor GIC bug where HPPIR reads weren't honouring the interrupt-group-disable bits; sent a patch - reviewed the latest STM32L4x5 UART patchset -- PMM

LLVM buildbot clang-aarch64-full-2stage

by orlando.hyams＠sony.com

Hi, I noticed this address registered as the admin for this LLVM buildbot - https://lab.llvm.org/buildbot/#/workers/134). I caused a failure at the start of the week (https://lab.llvm.org/buildbot/#/builders/179/builds/9629). I think it's a build (or test) configuration problem as outlined in this small PR https://github.com/llvm/llvm-zorg/pull/139. I can see the bot is currently failing now too (https://lab.llvm.org/buildbot/#/builders/179/builds/9681). I haven't looked at it closely but given the same tests are failing in a similar way (a different bitcode error from LLD), I imagine that might also be fixed by my llvm-zorg pull request above? Please can someone look at the llvm-zorg pull request when you have a spare moment? I have my LLVM change that caused the initial failure reverted in the meantime. Thanks, Orlando
