在你提供的 GCC 命令中,使用了多个选项来编译代码,其中包括-O0和-Os这两个优化级别选项。正如之前提到的,如果同时指定多个优化选项,最后一个会生效。因此,在这个命令中,-O0会覆盖-Os。 但是,尽管你已启用调试信息 (-g) 并且禁用了优化 (-O0),仍然可能存在其他问题导致 GDB 无法调试。以下是一些常见原因和解...

常量相关的运算的编译阶段完成。比如C++11引入了constexp,比如可以使用GCC的__builtin_constant_p来判断值是否常量,然后对常量进行编译时得出结果。举例网络序主机序转换 其中rte_constant_bswap32的实现 5)使用CPU指令 现代CPU提供很多指令可直接完成常见功能,比如大小端转换,x86有bswap指令直接支持了。 这个实现,也是G...

./configure CFLAGS="-g -O2 -msse4.2" If you are on a different processor and don't know what flags to choose, we recommend using‘-march=native’settings. With this, GCC will detect the processor and automatically set the appropriate flags for it. Do not use this method if you are co...
