-fsanitize=address选项:启用 AddressSanitizer,用于检测内存越界和使用释放后内存错误。 -fsanitize=thread选项:启用 ThreadSanitizer,用于检测数据竞争错误。 -fsanitize=leak选项:启用 LeakSanitizer,用于检测内存泄漏。 -fsanitize=undefined选项:启用 UndefinedBehaviorSanitizer,用于检测各种未定义行为。 步骤: 编译源文件时...
要在GCC C++编译器中进行静态分析,您可以使用-fsanitize=address(用于内存错误检测)、-fsanitize=undefined(用于未定义行为检测)等选项 打开终端或命令提示符。 转到您的C++源代码文件所在的目录。例如,如果您的源代码文件名为main.cpp,并且位于/home/user/my_project目录中,则输入以下命令: cd /home/user/my_proj...
-static-liblsan 当-fsanitize=leak选项用于链接程序,GCC驱动程序自动链接libtsan。如果libtsan可以作为共享库使用,并且-static选项未使用,则此链接指向的动态的libtsan。-static-liblsan选项指示GCC驱动程序链接静态的libtsan,而不必静态链接其他库。 -static-libubsan 当-fsanitize=undefined选项用于链接程序,GCC驱动...
-fsanitize=address 选项用于检测内存访问错误。-fsanitize=undefined 选项检测未定义行为。-fomit-frame-pointer 选项在某些情况下可优化函数调用。 -ffast-math 选项可进行快速数学计算的优化,但可能降低精度。-Wshadow 选项警告变量的隐藏。-Wunused-variable 选项警告未使用的变量。-Wunused-function 选项警告未使用的...
