| <h5 class="subsubsection">9.3.3.1 ARM relocation generation</h5> |
| |
| <p><a name="index-data-relocations_002c-ARM-604"></a><a name="index-ARM-data-relocations-605"></a>Specific data relocations can be generated by putting the relocation name |
| in parentheses after the symbol name. For example: |
| |
| <pre class="smallexample"> .word foo(TARGET1) |
| </pre> |
| <p>This will generate an ‘<samp><span class="samp">R_ARM_TARGET1</span></samp>’ relocation against the symbol |
| <var>foo</var>. |
| The following relocations are supported: |
| <code>GOT</code>, |
| <code>GOTOFF</code>, |
| <code>TARGET1</code>, |
| <code>TARGET2</code>, |
| <code>SBREL</code>, |
| <code>TLSGD</code>, |
| <code>TLSLDM</code>, |
| <code>TLSLDO</code>, |
| <code>TLSDESC</code>, |
| <code>TLSCALL</code>, |
| <code>GOTTPOFF</code>, |
| <code>GOT_PREL</code> |
| and |
| <code>TPOFF</code>. |
| |
| <p>For compatibility with older toolchains the assembler also accepts |
| <code>(PLT)</code> after branch targets. This will generate the deprecated |
| ‘<samp><span class="samp">R_ARM_PLT32</span></samp>’ relocation. |
| |
| <p><a name="index-MOVW-and-MOVT-relocations_002c-ARM-606"></a>Relocations for ‘<samp><span class="samp">MOVW</span></samp>’ and ‘<samp><span class="samp">MOVT</span></samp>’ instructions can be generated |
| by prefixing the value with ‘<samp><span class="samp">#:lower16:</span></samp>’ and ‘<samp><span class="samp">#:upper16</span></samp>’ |
| respectively. For example to load the 32-bit address of foo into r0: |
| |
| <pre class="smallexample"> MOVW r0, #:lower16:foo |
| MOVT r0, #:upper16:foo |
| </pre> |
| </body></html> |
