    x86: Delay setting the iplt section alignment · b44ee3a8
    H.J. Lu authored
    Delay setting its alignment until we know it is non-empty.  Otherwise an
    empty iplt section may change vma and lma of the following sections, which
    triggers moving dot of the following section backwards, resulting in a
    warning and section lma not being set properly.  It later leads to a
    "File truncated" error.
