--- Comment #17 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
I am re-doing benchmarks now to see where we are standing with gcc9.
I have checked reducing max-inline-insns-single as Richard mentioned, reducing
to 200 or 300 basically brings one regression and that is CactusADM, about 29%.
I will experiment with the hints and see if I can tweak the metrics here.
