| <dl compact="compact"> |

| <dd><p>If the value doesn’t fit into a standard <code>movi</code> opcode, |
| <code>as</code> will replace the <code>movi</code> with a sequence of |

| </dd> |
| <dt><code>pt</code></dt> |
| <dd><p>This expands to a sequence of <code>movi</code> and <code>shori</code> opcode, |
| followed by a <code>ptrel</code> opcode, or to a <code>pta</code> or <code>ptb</code> |
| opcode, depending on the label referenced. |
