directives:

<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.

|

<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.
