No.
不。
Only on a function-by-function basis using the optimize pragma:
仅在逐个函数的基础上使用优化编译指示：
#pragma optimize( "[optimization-list]", {on | off} )
The optimize pragma must appear outside a function and takes effect at the first function defined after the pragma is seen. The on and off arguments turn options specified in the optimization-list on or off.
优化编译指示必须出现在函数外部，并在看到编译指示后定义的第一个函数生效。on 和 off 参数打开或关闭优化列表中指定的选项。
usage:
用法：
#pragma optimize( "", off )

#pragma optimize( "", on )
