Description
option
An assembler option.
The
.opt
directive sets the specified assembler options. These options affect the
assembly of instructions, effective addresses, and data. They also provide a
means of customizing the assembly listing output. Only options valid for the
68000 are supported by Texas Instruments.
Options
a16
a32
Set the size of unknown absolute displacements to either 16
or 32 bits (see section
3.5.4.2 Displacement Sizing
).
(Default:
a32
)
dlist
nodlist
Enable/disable full listing of data directive assembly. The
dlist
option allows the object code associated with data
directives (e.g.,

while the
nodlist
option permits only one line of object code
to be listed.

Texas Instruments).
