[libc-commits] [PATCH] D129776: [libc] Add nearest integer instructions to fputil.

[Thorsten via Phabricator via libc-commits]

tschuett added a comment.

I am probably wrong, but ...
The Arm® Architecture Reference Manual defines a feature called FEAT_FRINTTS. It was added with Armv8.5.
FEAT_FRINTTS, Floating-point to integer instructions.

`frintn` is probably only available on modern ARM cores ala iPhone 12 from 2020.
