<h3 class="section"><code>.size</code> (COFF version)</h3>



   <p>This directive is generated by compilers to include auxiliary debugging

information in the symbol table.  It is only permitted inside

<code>.def</code>/<code>.endef</code> pairs.



   <p><code>.size</code> is only meaningful when generating COFF format output; when

<code>as</code> is generating <code>b.out</code>, it accepts this directive but

ignores it.



<h3 class="section"><code>.size </code><var>name</var><code> , </code><var>expression</var><code></code> (ELF version)</h3>



   <p>This directive is used to set the size associated with a symbol <var>name</var>. 

The size in bytes is computed from <var>expression</var> which can make use of label

arithmetic.  This directive is typically used to set the size of function

symbols.
