This had a suspiciously large impact on code size (-4% on mafft with LTO): https://llvm-compile-time-tracker.com/compare.php?from=60dd0121c92e93a33cf39b5f7006923ac9e4f127&to=3d9beefc7d713ad8462d92427ccd17b9532ce904&stat=size-text Not necessarily a problem, but I didn't expect to see any significant impact from this patch.
