Arch Linux Looking To Employ LTO By Default, Possibly Raise x86-64 Requirements

Reading through my feed bumped into this
Following openSUSE Tumbleweed using LTO by default, Fedora 33 doing it too, and Ubuntu 21.04 set to ship with LTO'ed packages, Arch Linux is finally looking at enabling link-time optimizations by default for their package builds ... Another notable change being considered at the same time for Arch is using the x86-64-v2 microarchitecture level. This would make Arch Linux faster by allowing to assume some CPU instruction set extensions by default while still running on most x86-64 Intel/AMD hardware from over one decade. This is the same as RHEL9 set to require x86-64-v2 instead of vanilla x86-64.
