- " GAS supports one type of multi line comments:
- syn region asmComment start="/\*" end="\*/" contains=asmTodo
-
- " 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.
