Copy the characters in <var>str</var> to the object file. You may specify more than
|
|
one string to copy, separated by commas. Unless otherwise specified for a
|
|
particular machine, the assembler marks the end of each string with a 0 byte.
|
|
You can use any of the escape sequences described in <a href="Strings.html#Strings">Strings</a>.
|
|
|
|
<p>The variants <code>string16</code>, <code>string32</code> and <code>string64</code> differ from
|
|
the <code>string</code> pseudo opcode in that each 8-bit character from <var>str</var> is
|
|
copied and expanded to 16, 32 or 64 bits respectively. The expanded characters
|
|
are stored in target endianness byte order.
|
|
|
|
<p>Example:
|
|
<pre class="smallexample"> .string32 "BYE"
|
|
expands to:
|
|
.string "B\0\0\0Y\0\0\0E\0\0\0" /* On little endian targets. */
|
|
.string "\0\0\0B\0\0\0Y\0\0\0E" /* On big endian targets. */
|
|
</pre>
