> The atomic operations in gutil/ use inline assembly for each architecture. Chromium, which is the upstream for gutil, has switched to generic atomic operations instead: [https://github.com/chromium/chromium/blob/2ca8c5037021c9d2ecc00b787d58a31ed8fc8bcb/base/atomicops.h#L152]
>
> It would be nice to make the corresponding change and make our codebase more portable. I did a dry run of this and ran into some minor issues with compiling, but it looked feasible. I'll attach here: [^0001-WIP-on-generic-atomics.-Not-compiling-yet.patch]
