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 -Alexey _______________________________________________ linux-snps-arc mailing list linux-snps-arc@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/linux-snps-arc
