| |
| <h5 class="subsubsection">9.14.2.1 SVR4 compatibility options</h5> |
| |
| <dl> |
| <dt><code>-V</code><dd>Print assembler version. |
| <br><dt><code>-Qy</code><dd>Ignored. |
| <br><dt><code>-Qn</code><dd>Ignored. |
| </dl> |
| |
| <h5 class="subsubsection">9.14.2.2 Other options</h5> |
| |
| <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. |
