<p><a name="index-ARC-options-591"></a><a name="index-options-for-ARC-592"></a>
The following options control the type of CPU for which code is
assembled, and generic constraints on the code generated:
<dl>
<dt><code>-mcpu=</code><var>cpu</var><dd><a name="index-g_t_0040code_007b_002dmcpu_003d_0040var_007bcpu_007d_007d-command-line-option_002c-ARC-593"></a>Set architecture type and register usage for <var>cpu</var>. There are
also shortcut alias options available for backward compatibility and
convenience. Supported values for <var>cpu</var> are

</dl>
<p>Note: the <code>.cpu</code> directive can to be used to select a core
variant from within assembly code.

be marked as being encoded for a big-endian processor.
<p><a name="index-g_t_0040code_007b_002dEL_007d-command-line-option_002c-ARC-602"></a><br><dt><code>-EL</code><dd>This option specifies that the output generated by the assembler should
be marked as being encoded for a little-endian processor - this is the
default.

processors.
