<dt><code>-V</code><dd>Print assembler version.
|
||
|
|
<br><dt><code>-Qy</code><dd>Ignored.

<br><dt><code>-Qn</code><dd>Ignored.

<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.
|
||
|
|
<br><dt><code>-mxp</code><dd>Enable support for the i860XP instructions and control registers. By default,
|
||
|
|
this option is disabled so that only the base instruction set (i.e., i860XR)
|
||
|
|
is supported.
|
||
|
|
<br><dt><code>-mintel-syntax</code><dd>The i860 assembler defaults to AT&T/SVR4 syntax. This option enables the
|
||
|
|
Intel syntax.
