xcode – 命令行工具的静态分析器问题

尝试替换这个

-w -Xanalyzer -analyzer-disable-checker

用这个可笑的长线(继续向右滚动看全部)：

-w -Xanalyzer -analyzer-disable-checker -Xanalyzer alpha -Xanalyzer -analyzer-disable-checker -Xanalyzer core -Xanalyzer -analyzer-disable-checker -Xanalyzer cplusplus -Xanalyzer -analyzer-disable-checker -Xanalyzer deadcode -Xanalyzer -analyzer-disable-checker -Xanalyzer debug -Xanalyzer -analyzer-disable-checker -Xanalyzer llvm -Xanalyzer -analyzer-disable-checker -Xanalyzer osx -Xanalyzer -analyzer-disable-checker -Xanalyzer security -Xanalyzer -analyzer-disable-checker -Xanalyzer unix -Xanalyzer -analyzer-disable-checker -Xanalyzer insecureAPI

好的,所以这是我怎么做到的.看起来Clang具有“静态分析器检查器”的层次结构,您可以单独或通过组禁用它们.

作为一个例子,DeadStore检查器是“deadcode.DeadStores”,所以你可以禁用它：

-Xanalyzer -analyzer-disable-checker -Xanalyzer deadcode.DeadStores

或者,您可以通过仅指定“deadcode”来禁用所有与死码相关的检查器：

-Xanalyzer -analyzer-disable-checker -Xanalyzer deadcode

您可以使用此命令获取所有检查程序的列表：

clang -cc1 -analyzer-checker-help

它目前输出以下内容：

我上面提供的长命令行禁用了所有9个顶级跳棋：
alpha,core,cplusplus,deadcode,debug,llvm,osx,security和unix PLUS“insecureAPI”基于以下意见,因为它似乎禁用安全性也不会禁用security.insecureAPI.

希望这相当于不运行分析仪.
