clang-diagnostic-error 是Clang 编译器生成的一种诊断信息,表示在编译过程中遇到了错误。Clang 是一种开源的 C、C++、Objective-C 和 Objective-C++ 编译器,它通过静态分析生成诊断信息,帮助开发人员发现和解决问题。当编译器在代码中发现潜在的问题时,它会生成相应的诊断信息,如警告、错误等。clang-diagnostic-error...

下面的例子中将-Warc-performSelector-leaks 标记为错误，clang在编译时就会报错。clang会将push和pop范围内的-Warc-performSelector-leaks 都会标记为错误。设置忽略某种类型的警告，比如下面忽略-Warc-performSelector-leaks的警告：结合上面的 #pragma clang diagnostic进行使用 ...

When passing `fsanitize=function -mexecute-only` to Clang on an ARM target, it prints the following error: ``` error: invalid argument '-fsanitize=function' not allowed with 'arm-unknown-linux-gnueabi' ``` The error happens because `-fsanitize=function` is incompatible with execute-only ...
