<p><a name="index-M680x0-directives-1122"></a><a name="index-directives_002c-M680x0-1123"></a>In order to be compatible with the Sun assembler the 680x0 assembler
|
|
understands the following directives.

aligns the output to an even byte boundary.

for <var>name</var> are the same as for the <span class="option">-march</span> command line

option. This directive cannot be specified after

|
any instructions have been assembled. If it is given multiple times,
|
|
or in conjunction with the <span class="option">-march</span> option, all uses must be for
|
|
the same architecture and extension set.
