I think I do have some but first I'd like to get it reproduced myself. I just built v5.6 with help of both GCC 8.3.1- & 9.3.1-based toolchains and didn't see a single warning. So I guess I was doing something wrong.
FWIW
1. My GCC 8.3.1 toolchain was exactly this: https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases/download/arc-2019.09-release/arc_gnu_2019.09_prebuilt_uclibc_le_archs_linux_install.tar.gz
2. Linux kernel is vanilla v5.6.0
3. Configured and built as simple as: make axs103_smp_defconfig && make
