Reading through my feed bumped into this https://www.phoronix.com/scan.php?page=news_item&px=Arch-Linux-LTO-Proposed
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.
