Re: [PATCH v2] ARM: Block predication on atomics [PR111235]

With this it runs a few more tests. Yeah that's a wart that I don't like. armhf just implies the hard float ABI and came into being to help distinguish from the Base PCS for some of the distros at the time (2010s). However we didn't want to set a baseline arch at that time given the imminent arrival of v8-a and thus the specification of --with-arch , --with-fpu and --with-float became second nature to many of us working on it at that time. I can see how it can be confusing. With the advent of fpu=auto , I thought this could be made better but that is a matter for another patch and another discussion. However until then do remember to baseline to --with-arch , --with-fpu and --with-float . Unfortunate but needed. If there is a bug with --with-fpu=auto , good to articulate it as I understand that to be the state of the art.

Please try out various combinations of -march v7ve, v7-a , v8-a with the tool as each of them have slightly different rules.

While it is not policy yet to look at these bots but given the enthusiasm at Cauldron for patchwork and pre-commit CI and because all my armhf boxes are boxed up, I decided to do something a bit novel ! I tried reviewing this via patchwork https://patchwork.sourceware.org/project/gcc/patch/PAWPR08MB8982A6AA40749B7… and notice that https://ci.linaro.org/job/tcwg_gcc_build--master-arm-precommit/2393/artifac… says nothing could be built. Possibly worth double checking the status for it being a false negative as to why the build failed. It was green on patchwork but remembering that Green is not Green for CI in patchwork I clicked on the afore mentioned ci.linaro.org link and see that it's actually broken. regards Ramana

[ACTIVITY] report week ending 20 Oct

by Peter Maydell

Progress: * UM-2 [QEMU upstream maintainership] - post-holiday catchup on email and code review - respin and resend of a patch fixing a bug in rdma code - sent a target-arm pull request * QEMU-292 [ARMv8.3 FEAT_NV, Nested Virtualization] - did an initial read-through of the relevant portions of the Arm ARM to identify the work required here thanks -- PMM
