--- Comment #1 from Vladimir Makarov <vmakarov at gcc dot gnu.org> --- I can not reproduce it on Intel (13600K). GCC with patch and without the patch has the same score for lbm_s (11.4). But I see big lbm_s code increase with the patch (+0.87%). And this is suspenseful. In any case I will investigate what is changed in the code with the patch. If I have a solution I will run spec2017 on intel and a zen machine to check that there is no significant performance change. Probably I will find a solution on the next week.
