| <h4 class="subsection">9.40.3 SH64 Machine Directives</h4> |
| |
| <p>In addition to the SH directives, the SH64 provides the following |
| directives: |
| </p> |
| <a name="index-SH64-machine-directives"></a> |
| <a name="index-machine-directives_002c-SH64"></a> |
| |
| <dl compact="compact"> |
| <dt><code>.mode [shmedia|shcompact]</code></dt> |
| <dt><code>.isa [shmedia|shcompact]</code></dt> |
| <dd><p>Specify the ISA for the following instructions (the two directives are |
| equivalent). Note that programs such as <code>objdump</code> rely on symbolic |
| labels to determine when such mode switches occur (by checking the least |
| significant bit of the label’s address), so such mode/isa changes should |
| always be followed by a label (in practice, this is true anyway). Note |
| that you cannot use these directives if you didn’t specify an ISA on the |
| command line. |
| </p> |
| </dd> |
| <dt><code>.abi [32|64]</code></dt> |
| <dd><p>Specify the ABI for the following instructions. Note that you cannot use |
| this directive unless you specified an ABI on the command line, and the |
| ABIs specified must match. |
| </p> |
