Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Any kind of such code goes strongly against build reproduceability, -fcompare-debug etc., so not sure it would be really appreciated, it is a direction against various changes done in gcc lately. I think if you need something like that just pass -DRANDOM=`dd if=/dev/random bs=8 count=1 2>/dev/null | md5sum | awk '{print $1}'` or something similar.
