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