--- Comment #15 from Richard Biener <rguenth at gcc dot gnu.org> --- (In reply to Tom de Vries from comment #13) > F.i., an open question for me is the following: I'm now using > -flto-partition=none for testing, but maybe 1to1 should yield better results? I guess it better mimics how the testcases are set up, but I think the differences will be due to the other issues so the exact partitioning shouldn't matter (you likely always get a single partition and thus behavior equal to -flto-partition=none or -flto-partition=one by default). -flto-partition=none will be faster because it elides the LTRANS IL streaming.
