I want to compile with optimization -O1, but there is a certain flag that it turns on that I do not want to use. How do I turn it off?

推荐答案

通常有一个等效的no标志。例如， fstrict-aliasing 可以通过 fno-strict-aliasing 关闭。检查gcc文档是否有更多标记。

There is usually an equivalent 'no' flag. For example, fstrict-aliasing can be turned off by fno-strict-aliasing. Check the gcc docs for more flags.
