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