Opened PR98779 about issues in libgcc wrt -mpure-code. * infra: - reviewed patches. - ABE's make-check-gcc is currently broken == Next == * GCC/cortex-M testing improvements & fixes * cortex-m benchmarking * MVE auto-vectorization/intrinsics improvements

[ACTIVITY] report week ending 22 Jan

by Peter Maydell

Progress: * UM-2 [QEMU upstream maintainership] + Code review (including RTH's MTE-for-user-mode-emulation) + Investigating an intermittent failure of a test case involving an s390 guest on aarch64 hosts... * QEMU-364 [QEMU support for ARMv8.1-M extensions] + Converted the ARMSSE (IoTKit/SSE-200) code over to use the Clock framework, which was added to QEMU after ARMSSE was first written. (This is a prereq for adding the new-in-SSE-300 timer device, which will use Clocks.) Sent the patches out for review. I'm currently experimenting with a schedule of: Mon: JIRA task work; Tue: code review; Thu: JIRA task work; Fri: misc upstream thanks -- PMM

Progress: * UM-2 [QEMU upstream maintainership] + code review, pullreq + fixed the "breaks a gitlab CI run" issue with the 'merge docs into a single sphinx manual' patch * QEMU-364 [QEMU support for ARMv8.1-M extensions] + Progress with the SSE-300 model: - finished model of new timer device - updated iotkit-sysctl register block with SSE-300 specific behaviour - implemented simple dummy model of new CPU<N>_PWRCTRL register block - made sse-300 code more data-driven so it can handle sse-300 putting some of the devices at different places thanks -- PMM
