<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.
