17810: drivers/slipdev: implement sleep states r=benpicco a=benpicco 18348: sys/net/gnrc/pktbuf_static: make use of alignas() r=maribu a=maribu ### Contribution description Since we are now using C11, we can make use of `alignas()` provided by `<stdalign.h>` to make the alignment code easier to read. ### Testing procedure I didn't expect this to change binaries, but is safes 4 bytes. `elf_diff` shows that the compiler (at least GCC 11.3.0) was not able to detect that `gnrc_pktbuf_static_buf` was just an alias for `_pktbuf_buf`. That makes sense since it would be hard without LTO to rule out external writes to `gnrc_pktbuf_static_buf`, unless one would have added a `const` (to the pointer, not to the data the pointer points to). The [output of `elf_diff`](https://mari-bu.de/pr_18348_gnrc_pktbuf_static_elf_diff.html) looks otherwise quite unscary. Also: ``` $ make BOARD=nucleo-f767zi -C tests/unittests/ tests-pktbuf flash test make: Entering directory '/home/maribu/Repos/software/RIOT/tests/unittests' Building application "tests_unittests" for "nucleo-f767zi" with MCU "stm32". [...] Welcome to pyterm! Type '/exit' to exit. READY s START ............................................. OK (45 tests) make: Leaving directory '/home/maribu/Repos/software/RIOT/tests/unittests' ``` ### Issues/PRs references None 19120: CI: seperate check-labels and check-commits workflows r=maribu a=kaspar030 Co-authored-by: Benjamin Valentin <benjamin.valentin@ml-pa.com> Co-authored-by: Marian Buschsieweke <marian.buschsieweke@ovgu.de> Co-authored-by: Kaspar Schleiser <kaspar@schleiser.de> |
