== Progress == * GCC upstream validation: - reported a couple of failures/regressions

* GCC: - comparing testsuite results for cortex-m3 and cortex-m33 with cortex-a9 to check what cortex-M problem there are. Fixed a few testcases. Managed to use qemu-system-arm to run cortex-m33 code with CMSE features. (Thanks to Peter Maydell for the help!)

* misc: - infra fixes / troubleshooting / reviews

== Next == * FDPIC GDB * GCC/cortex-M
