The best way to see current status is probably to go to https://lnt.opensuse.org/db_default/v4/SPEC/spec_report/branch?sorting=gcc-7%2Cgcc-8%2Cgcc-9%2Cgcc-10%2Cgcc-11%2Cgcc-trunk and then enter "554.roms" into the "test name filter" edit field. On Zen3 we now regress by 5.63% compared to GCC 7 at -O2. On Zen2 we now regress by 8.35% compared to GCC 7 at -O2. On Zen1 we now regress by 11.15% compared to GCC 7 at -O2. On s Kabylake "client" CPU we now regress by 9.06% compared to GCC 7 at -O2. On a Cascadelake "server" CPU we now regresss by 7.84% compared to GCC 7 at -O2. ^ permalink raw reply [flat|nested] 3+ messages in thread

I no longer track zen1. LNT largely confirms these observations although it tracks -O2 mostly only with LTO. ^ permalink raw reply [flat|nested] 3+ messages in thread
