--- Comment #19 from Jan Hubicka <hubicka at gcc dot gnu.org> --- Seems that the multi-target speculation fallout is now fixed and also indirect call profiling works similarly as to gcc9 now if the reproducibility logic is disabled. I re-benchmarked Firefox. Reproducible merging still causes regression, now there are two - perf_reftest singleton analysed here and responsiveness. Both seems reproducible https://treeherder.mozilla.org/perf.html#/compare?originalProject=try&originalRevision=5a4c0ae2020316660ae61035e0d0d826e26cab2f&newProject=try&newRevision=2de47e4772cfab453a21854d7cd9ff979b71b42e&framework=1&pageTitle=Non-reproducible+compared+to+reproducible+topn+merging Subtests of perfetest still show 20%+ regression in the getters: https://treeherder.mozilla.org/perf.html#/comparesubtest?originalProject=try&newProject=try&newRevision=2de47e4772cfab453a21854d7cd9ff979b71b42e&originalSignature=1905485&newSignature=1905485&framework=1&originalRevision=5a4c0ae2020316660ae61035e0d0d826e26cab2f
