| <p>The RL78 has three modifiers that adjust the relocations used by the |
| linker: |
| </p> |
| <dl compact="compact"> |
| <dt><code>%lo16()</code></dt> |
| <dd> |
| <p>When loading a 20-bit (or wider) address into registers, this modifier |
| selects the 16 least significant bits. |
| </p> |
| <div class="smallexample"> |
| <pre class="smallexample"> movw ax,#%lo16(_sym) |
| </pre></div> |
| |
| </dd> |
| <dt><code>%hi16()</code></dt> |
| <dd> |
| <p>When loading a 20-bit (or wider) address into registers, this modifier |
| selects the 16 most significant bits. |
| </p> |
| <div class="smallexample"> |
| <pre class="smallexample"> movw ax,#%hi16(_sym) |
| </pre></div> |
| |
| </dd> |
| <dt><code>%hi8()</code></dt> |
| <dd> |
| <p>When loading a 20-bit (or wider) address into registers, this modifier |
| selects the 8 bits that would go into CS or ES (i.e. bits 23..16). |
| </p> |
| <div class="smallexample"> |
