Unlike in C/C++ however, 57" a backslash ending a C++ style comment does not extend the comment to the 58" next line (hence the syntax region does not define 'skip="\\$"') 59syn region asmComment start="//" end="$" keepend contains=asmTodo 60 61" Line comment characters depend on the target architecture and command line 62" options and some comments may double as logical line number directives or 63" preprocessor commands. This situation is described at 64" http://sourceware.org/binutils/docs-2.22/as/Comments.html 65" Some line comment characters have other meanings for other targets. For 66" example, .type directives may use the `@' character which is also an ARM 67" comment marker. 68" As a compromise to accommodate what I arbitrarily assume to be the most 69" frequently used features of the most popular architectures (and also the 70" non-GNU assembly languages that use this syntax file because their asm files 71" are also named *.asm), the following are used as line comment characters: 72syn match asmComment "[#;!|].*" contains=asmTodo 73 74" Side effects of this include: 75" - When `;' is used to separate statements on the same line (many targets 76" support this), all statements except the first get highlighted as 77" comments. As a remedy, remove `;' from the above. 78" - ARM comments are not highlighted correctly. For ARM, uncomment the 79" following two lines and comment the one above. 80"syn match asmComment "@.*" contains=asmTodo 81"syn match asmComment "^#.*" contains=asmTodo 82 83" Advanced users of specific architectures will probably want to change the 84" comment highlighting or use a specific, more comprehensive syntax file. 85 86syn match asmInclude "\.include" 87syn match asmCond "\.if" 88syn match asmCond "\.else" 89syn match asmCond "\.endif" 90syn match asmMacro "\.macro" 91syn match asmMacro "\.endm" 92 93" Assembler directives start with a '.' and may contain upper case (e.g., 94" .ABORT), numbers (e.g., .p2align), dash (e.g., .app-file) and underscore in 95" CFI directives (e.g., .cfi_startproc).
