[ACTIVITY] report week ending 6 Jul
Progress (short week, 3 days): * UM-2 [QEMU upstream maintainership] - softfreeze is next week, so spent some time putting together a pull request, fixing the bugs which the CI tests found in it, etc * QEMU-422 [QEMU Arm Neoverse V1 vCPU for TCG] - now that we implement all the necessary features (excluding some trace/profiling type stuff that is out-of-scope for QEMU, and also FEAT_NV that we might come back to later), sent out the patchset to define a 'neoverse-v1' CPU type for QEMU -- PMM ___ linaro-toolchain mailing list -- linaro-toolchain@lists.linaro.org To unsubscribe send an email to linaro-toolchain-le...@lists.linaro.org

[TCWG-1368] Tracked down libfuzzer buildbot failures on aarch64 and raised PR [TCWG-1424] Use profile information for size optimisation - Decided to use clang's 2-stage PGO build as next experiment with compile times on the full test suite as the performance benchmarks - Spent rather too much time trying to inject an extra c-flag into the right stage of the bootstrap builds. As a consolation I know a little bit more about the bootstrap builds. - Just measuring code size the profile guided feedback builds of clang are roughly 33% larger than standard clang, with cold functions optimised for size this drops to 25% larger. Still waiting for performance figures for all runs. It is looking like in its current formulation the size optimisation might offer most of the benefits of PGO but with a lower code size impact. It misses the original goal of keeping the performance of non-PGO optimisation but lower overall size. [Misc] Tracked down a LLD static build failure with a recent glibc. Looks like it won't affect Arm and AArch64 as it is related to X86 relaxed got relocations to ifunc resolvers.

Progress: * VIRT-65 [QEMU upstream maintainership] + softfreeze-related maintenance work + investigating reported bug with CMSDK timer device model: couldn't reproduce hangs, but sent patches which fix various issues + code review: - various patches by the Outreachy/GSoC interns for the v6M/microbit work - a few OSX UI bugfix patches + scrub through some recently filed bugs to see what might be worth investigating before the release + first pass through KVM Forum talk submissions thanks -- PMM ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org https://lists.linaro.org/mailman/listinfo/linaro-toolchain
