Overview

template<typename T>
class pw::RuntimeInitGlobal< T >

Declares a global variable that is initialized at runtime and whose destructor is never run.

This class is the same as pw::NoDestructor, except that pw::NoDestructor may be constinit if T is constexpr constructible. pw::RuntimeInitGlobal instances can never be constinit. pw::RuntimeInitGlobal prevents constant initialization inserting empty volatile inline assembly.

Note: RuntimeInitGlobal should only be used when T should not be constant initialized; otherwise, use pw::NoDestructor. Constant initialization moves objects from .bss to .data. This can increase binary size if the object is larger than the code that initializes it.

Warning: Misuse of RuntimeInitGlobal can cause memory leaks and other problems. RuntimeInitGlobal should only be used for global variables.
