有没有任何编译器IGNORE C ++标准关于默认内联函数？ [英] Are there any compilers that IGNORE C++ standard about default inline functions?

问题描述

C ++ ISO标准说：

C++ ISO standard says, that:

"A function defined within a class definition is an inline function."

是否有任何编译器忽略此规则？

错误与inlineD内联 - 我的问题是如果有一个编译器，不会在那里的内联建议它应该）

Are there any compilers that IGNORE this rule?
(please, do not mistake inline with inlineD - my question is if there is a compiler, that wont put there that inline suggestion that it should)

推荐答案

你似乎误解了内联是什么意思。这并不意味着函数将自动内联;根据7.1.2-2，它表示优先使用行内替换。

You seem to be misunderstanding what "inline" means. It doesn't mean functions will automatically be inlined; according to 7.1.2-2 it indicates that inline substitution is to be preferred.

因此，你不能知道函数是否从代码中标记为内联，因为编译器可以自由决定一种或另一种方式。这只是一个编译器提示。

Therefore, you can't tell whether a function is labeled inline or not from the code, since the compiler is free to decide one way or another. It's just a compiler hint.
