Description Steffen Hau 2018-05-11 18:23:41 UTC 
Please integrate upstream patch in 8.1.0 patchset.
Comment 1 Sergei Trofimovich (RETIRED) gentoo-dev 2018-05-11 21:20:54 UTC 
Queued for 8.1.0 as 96_all_lto-O2-PR85655.patch : https://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo/src/patchsets/gcc/8.1.0/gentoo/

We'll cut new patchset once more things accumulate (or after a few weeks).
You can drop the patch into /etc/portage/patches/sys-devel/gcc/ to use user-patches mechanism meanwhile.
