[Nikita Popov via Phabricator via llvm-commits]

FYI there seems to be some (but not very large) compile-time impact on ClamAV: https://llvm-compile-time-tracker.com/compare.php?from=e60f147324b64f7740de58e6b936cdc0e26daadd&to=36911971a58d1ba8b15e97790ac816eaadb0603e&stat=instructions

The file with the largest impact is libclamav_htmlnorm.c with 3.4% regression in NewPM-O3 (and 5.6% in NewPM-ReleaseLTO-g). Might be worth taking a look.
