Looking at the kernel setup code for sparc64, support for V8+ seems to be a standard capability that is available on all 64-bit SPARC targets. The function init_sparc64_elf_hwcap(void) [1] unconditionally enables it with: cap |= (AV_SPARC_MUL32 | AV_SPARC_DIV32 | AV_SPARC_V8PLUS); So, I think it should be safe and enable V8+ on sparc64 for 32-bit targets the same way it is done on Solaris. > [1] > https://github.com/torvalds/linux/blob/5bfc75d92efd494db37f5c4c173d3639d4772966/arch/sparc/kernel/setup_64.c#L531
