<p>General-purpose registers are represented by predefined symbols of the
|
|
form ‘<samp>r<var>N</var></samp>’, where <var>N</var> represents a number between
|
|
<code>0</code> and <code>63</code>. However, the following registers have
|
|
canonical names that must be used instead:
|
|
</p>
|
|
<dl compact="compact">
|

<dt><code>r54</code></dt>
|

<dd><p>sp

<p>The assembler will emit a warning if a numeric name is used instead of
|
|
the canonical name. The <code>.no_require_canonical_reg_names</code>
|
|
assembler pseudo-op turns off this
|
|
warning. <code>.require_canonical_reg_names</code> turns it back on.
