### How to downgrade gcc (from v 8 to v 7)

I'm running gcc version 8 and I want to downgrade it to version 7 (because I want to try to compile kernel with gcc 7 to see if it still compile-errors!).
How to do that? I'm assuming that I have to use dnf. I'm on Fedora 28 (sort of)

\$ gcc --version
gcc (GCC) 8.1.1 20180712 (Red Hat 8.1.1-5)
