<dl><dt><code>-marc[5|6|7|8]</code><dd>This option selects the core processor variant. Using

is also the default.

be marked as being encoded for a big-endian processor.

<p><a name="index-_0040code_007b_002dEL_007d-command-line-option_002c-ARC-541"></a><br><dt><code>-EL</code><dd>This option specifies that the output generated by the assembler should
