MISRA C:2012 Rule 5.9
Identifiers that define objects or functions with internal linkage should be unique
描述
默认 Polyspace® as You Code 分析中反激活了此检查项。请参阅Checkers Deactivated in Polyspace as You Code Analysis (Polyspace Access)。
规则定义
Identifiers that define objects or functions with internal linkage should be unique 1 .
理由
具有内部链接的标识符仅在声明它们的转换单元中可访问。这些标识符通常被声明为 static。如果这种标识符不唯一,代码可能变得难以理解,并导致意外的结果。
Polyspace 实现
Polyspace 会标记在所有转换单元中不唯一的 static 变量名称。
故障排除
如果您预期会出现违规,但未看到该违规,请参阅诊断为何编码规范违规未按预期显示。
