| <h4 class="subsection">9.28.3 Syntax</h4> |
| |
| <p>The assembly syntax is supposed to be upward compatible with that |
| described in Sections 1.3 and 1.4 of ‘<samp>The Art of Computer |
| Programming, Volume 1</samp>’. Draft versions of those chapters as well as other |
| MMIX information is located at |
| <a name="mmixsite"></a><a href="http://www-cs-faculty.stanford.edu/~knuth/mmix-news.html">http://www-cs-faculty.stanford.edu/~knuth/mmix-news.html</a>. |
| Most code examples from the mmixal package located there should work |
| unmodified when assembled and linked as single files, with a few |
| noteworthy exceptions (see <a href="MMIX_002dmmixal.html#MMIX_002dmmixal">MMIX-mmixal</a>). |
| </p> |
| <p>Before an instruction is emitted, the current location is aligned to the |
| next four-byte boundary. If a label is defined at the beginning of the |
| line, its value will be the aligned value. |
| </p> |
| <p>In addition to the traditional hex-prefix ‘<samp>0x</samp>’, a hexadecimal number |
| can also be specified by the prefix character ‘<samp>#</samp>’. |
| </p> |
| <p>After all operands to an MMIX instruction or directive have been |
| specified, the rest of the line is ignored, treated as a comment. |
