For some platform (e.g. loongarch64),
fstat
andfstatat
system calls are not implemented in Linux kernel. Usestatx
system call to implementos.fstat
andos.fstat
if it exists.This will benefit adding loongarch64 support to zig. See patch here: yxd-ym/zig-bootstrap#1
The implementation comes from the idea of golang's implementation https://go-review.googlesource.com/c/go/+/407694
