--- Comment #6 from Erick Ochoa <erick.oc...@theobroma-systems.com> --- Thanks, that helps. I'm just going to make the note that the behaviour I was describing involves the use of -flto-partition=none and not just -flto. With just -flto I never needed to add an explicit output file. With -flto-partition=none, if one doesn't specify the output file, the dump file remains on the /tmp folder.
