When you post, please include the libc-alpha list (I think they are fine
with cross-posting), maybe only for the cover letter as that's where the
useful discussion seems to happen.

It's interesting to re-read some older posts on x32 (it's not just
time_t affected, though probably that the most visible):

Basically for x32 POSIX compliance doesn't seem too critical. IIUC, the
x32 wasn't added to solve a 32-bit compatibility problem but as a
potential optimisation for specific cases.

On ARM OTOH, (one of?) the main goal for AArch64 ILP32 is to offer a
solution for 32-bit code when AArch32 is not present (and potentially
slightly more optimal than AArch32 but not necessarily when compared to
