The Ubicom IP2K version of @code{@value{AS}} has a few machine
|
|
dependent options:
|
|
|
|
@table @code
|
|
@item -mip2022ext
|
|
@cindex @samp{-mip2022ext} option, IP2022
|
|
@cindex architecture options, IP2022
|
|
@cindex IP2K architecture options
|
|
@code{@value{AS}} can assemble the extended IP2022 instructions, but
|
|
it will only do so if this is specifically allowed via this command
|
|
line option.
|
|
|
|
@item -mip2022
|
|
@cindex @samp{-mip2022} option, IP2K
|
|
@cindex architecture options, IP2K
|
|
@cindex IP2K architecture options
|
|
This option restores the assembler's default behaviour of not
|
|
permitting the extended IP2022 instructions to be assembled.

@cindex line comment character, IP2K
|
|
@cindex IP2K line comment character
|
|
The presence of a @samp{;} on a line indicates the start of a comment
|
|
that extends to the end of the current line.
|
|
|
|
If a @samp{#} appears as the first character of a line, the whole line
|
|
is treated as a comment, but in this case the line can also be a
|
|
logical line number directive (@pxref{Comments}) or a preprocessor
|
|
control command (@pxref{Preprocessing}).
|
|
|
|
@cindex line separator, IP2K
|
|
@cindex statement separator, IP2K
|
|
@cindex IP2K line separator
|
|
The IP2K assembler does not currently support a line separator
|
|
character.
