The glibc man page states: > The underlying system call employed by the glibc fstatat() wrapper > function is actually called fstatat64() or, on some architectures, > newfstatat(). So, this seems like a mistake on the part of LLVM, if it's documented to not be available on all architectures. But, if it can be enabled on sparc64 Linux, then that should be done, sure.
