These two rules: @other@ identifier r.i; position p != r.p; @@ i@p @s depends on !other@ identifier r.i; expression e; @@ #define i e The first rule checks for uses that are different than the one in the MODULE_XXX call. The second rule only matches the #define if the first rule fails, ie there are no other uses. julia -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
