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