| " GAS supports one type of multi line comments: |

| |
| " GAS (undocumentedly?) supports C++ style comments. Unlike in C/C++ however, |
| " a backslash ending a C++ style comment does not extend the comment to the |
| " next line (hence the syntax region does not define 'skip="\\$"') |
| syn region asmComment start="//" end="$" keepend contains=asmTodo |
| |
| " Line comment characters depend on the target architecture and command line |
| " options and some comments may double as logical line number directives or |
| " preprocessor commands. This situation is described at |
| " http://sourceware.org/binutils/docs-2.22/as/Comments.html |
| " Some line comment characters have other meanings for other targets. For |
| " example, .type directives may use the `@' character which is also an ARM |
| " comment marker. |
| " As a compromise to accommodate what I arbitrarily assume to be the most |
| " frequently used features of the most popular architectures (and also the |
| " non-GNU assembly languages that use this syntax file because their asm files |
| " are also named *.asm), the following are used as line comment characters: |
| syn match asmComment "[#;!|].*" contains=asmTodo |
| |
| " Side effects of this include: |
| " - When `;' is used to separate statements on the same line (many targets |
| " support this), all statements except the first get highlighted as |
| " comments. As a remedy, remove `;' from the above. |
| " - ARM comments are not highlighted correctly. For ARM, uncomment the |
| " following two lines and comment the one above. |
| "syn match asmComment "@.*" contains=asmTodo |
| "syn match asmComment "^#.*" contains=asmTodo |
| |
| " Advanced users of specific architectures will probably want to change the |
| " comment highlighting or use a specific, more comprehensive syntax file. |
