| 26 | The Ubicom IP2K version of @code{@value{AS}} has a few machine |
| 27 | dependent options: |
| 28 | |
| 29 | @table @code |
| 30 | @item -mip2022ext |
| 31 | @cindex @samp{-mip2022ext} option, IP2022 |
| 32 | @cindex architecture options, IP2022 |
| 33 | @cindex IP2K architecture options |
| 34 | @code{@value{AS}} can assemble the extended IP2022 instructions, but |
| 35 | it will only do so if this is specifically allowed via this command |
| 36 | line option. |
| 37 | |
| 38 | @item -mip2022 |
| 39 | @cindex @samp{-mip2022} option, IP2K |
| 40 | @cindex architecture options, IP2K |
| 41 | @cindex IP2K architecture options |
| 42 | This option restores the assembler's default behaviour of not |
| 43 | permitting the extended IP2022 instructions to be assembled. |

| 56 | @cindex line comment character, IP2K |
| 57 | @cindex IP2K line comment character |
| 58 | The presence of a @samp{;} on a line indicates the start of a comment |
| 59 | that extends to the end of the current line. |
| 60 | |
| 61 | If a @samp{#} appears as the first character of a line, the whole line |
| 62 | is treated as a comment, but in this case the line can also be a |
| 63 | logical line number directive (@pxref{Comments}) or a preprocessor |
| 64 | control command (@pxref{Preprocessing}). |
| 65 | |
| 66 | @cindex line separator, IP2K |
| 67 | @cindex statement separator, IP2K |
| 68 | @cindex IP2K line separator |
| 69 | The IP2K assembler does not currently support a line separator |
| 70 | character. |
