<dt><code>-V</code>

     <dd>Print assembler version.

     <dl>

<dt><code>-EL</code>

     <dd>Select little endian output (this is the default). 

<br><dt><code>-EB</code>

     <dd>Select big endian output. Note that the i860 always reads instructions

as little endian data, so this option only effects data and not

instructions. 

<br><dt><code>-mwarn-expand</code>

     <dd>Emit a warning message if any pseudo-instruction expansions occurred. 

For example, a <code>or</code> instruction with an immediate larger than 16-bits

will be expanded into two instructions. This is a very undesirable feature to

rely on, so this flag can help detect any code where it happens. One

use of it, for instance, has been to find and eliminate any place

where <code>gcc</code> may emit these pseudo-instructions.
