--- Comment #2 from David Brown <david at westcontrol dot com> ---
For reference, the issue is also discussed here:
https://bugs.launchpad.net/gcc-arm-embedded/+bug/1722849
For this particular case, there are usable workarounds (with extra dependencies
or memory clobbers). But "asm volatile" statements should not be moveable
across other asm volatile statements, volatile memory accesses, or other
observable behaviour. (It is fine that they can be moved across other code,
just like other volatile accesses.)
