You get those old models with just 'long'. Fortunately LoongArch ILP32 ABI is not finalized yet (there's no 32-bit kernel and 64-bit kernel does not support 32-bit userspace yet) so we can still make it happen to use struct statx as (userspace) struct stat... -- Xi Ruoyao <xry111@xxxxxxxxxxx> School of Aerospace Science and Technology, Xidian University
