--- Comment #3 from Martin Jambor <jamborm at gcc dot gnu.org> ---
I can reliably bisect this to r14-4972-g8aa47713701b1f (Vladimir's [RA]: Add
cost calculation for reg equivalence invariants) on a similar zen2 machine.
But it seems zen2 specific, I did not see any performance difference (this is
generic march/tuning) on znver4, for example. So it may be quite hard to
analyze and fix, even though the regression is big :-/
