It appears in Ebuild HOWTO as: "replace-cpu-flags This replaces any -march=... or -mcpu=... flags that contain the second argument with the first." While flag-o-matic.eclass says: #### replace-cpu-flags <old.cpus> <new.cpu> ### # Replace march/mcpu flags that specify <old.cpus> # with flags that specify <new.cpu> Reproducible: Always
Note that the change was reported in bug #60597
Fixed.
