now read directory entries in batches to reduce the number of system calls,
      improving performance up to 30%.

      When <a href="/pkg/io#Copy"><code>io.Copy</code></a> copies
      from a <code>File</code> to a <code>net.UnixConn</code>,
      it will now use Linux's <code>sendfile(2)</code> system call if possible,

register, even on architectures with a hardware frame pointer.

For assembly functions with Go prototypes, <code>go</code> <code>vet</code> will check that the argument names
and offsets match.
On 32-bit systems, the low and high 32 bits of a 64-bit value are distinguished by adding
a <code>_lo</code> or <code>_hi</code> suffix to the name, as in <code>arg_lo+0(FP)</code> or <code>arg_hi+4(FP)</code>.
