与-Wstringop-overflow=3类似,可能会对一些良性代码发出警告。 应用场景:这是最严格的设置,适用于需要最大化内存安全检测的场景,但可能导致大量误报。 2.-Wno-stringop-overread 行为:该选项控制是否对那些可能读取到源序列末尾之后的字符串操作函数调用发出警告。 特性: 默认情况下启用,编译器会检查类似memchr、strc...

For now, you can disable the -Wstringop-overflow warning by adding -Wno-error=stringop-overflow to the TBB_WARNING_LEVEL variable in the corresponding cmake file. This file is located at <tbb_sources>/cmake/compilers/GNU.cmake. See #823 for additional warnings you might need to suppress ...
对未知尺寸字符串的小块操作使用内联代 码,而对大块操作仍然调用库函数,这是比"-minline-all-stringops"更聪明的策略。决定策略的算法可以通 过"-mstringop-strategy"控制。 -momit-leaf-frame-pointer 不为叶子函数在寄存器中保存栈指针,这样可以节省寄存器,但是将会使调试 变的困难。注意:不要与 -fomit-frame-...
