<h4 class="section">Options</h4>



   <p>The i386 version of <code>as</code> has a few machine

dependent options:



     <dl>

<dt><code>--32 | --64</code>

     <dd>Select the word size, either 32 bits or 64 bits. Selecting 32-bit

implies Intel i386 architecture, while 64-bit implies AMD x86-64

architecture.



     <p>These options are only available with the ELF object file format, and

require that the necessary BFD support has been included (on a 32-bit

platform you have to add -enable-64-bit-bfd to configure enable 64-bit

usage and use x86-64 as target platform).
