For 64" example, .type directives may use the `@' character which is also an ARM 65" comment marker. 66" As a compromise to accommodate what I arbitrarily assume to be the most 67" frequently used features of the most popular architectures (and also the 68" non-GNU assembly languages that use this syntax file because their asm files 69" are also named *.asm), the following are used as line comment characters: 70syn match asmComment "[#;!|].*" contains=asmTodo 71 72" Side effects of this include: 73" - When `;' is used to separate statements on the same line (many targets 74" support this), all statements except the first get highlighted as 75" comments. As a remedy, remove `;' from the above. 76" - ARM comments are not highlighted correctly.
