I was compiling natively on the BeagleV board. The same result can be observed in a chroot using qemu-riscv64-static. chroot: gcc (Debian 11-20210327-1) 11.0.1 20210327 BeagleV: gcc (GCC) 10.3.1 20210422 (Red Hat 10.3.1-1) Best regards Heinrich
RISC-V GCC sounds like cross-compile for RISC-V+ _init = .; .u_boot_list : { KEEP(*(SORT(.u_boot_list*))); } --Regards, Bin
