In this article we compared different behavior of static, inline and static inline free functions in compiled binary. All the following test was done under g++ 7.1.1 on Linux amd64, ELF64.

Test sources

header.hpp

#pragma once

inline int only_inline() { return 42; }
static int only_static() { return 42; }

	template<typename T>
	inline void hash_combine(std::size_t& seed, const T& val)
	{
	std::hash<T> hasher;
	seed ^= hasher(val) + 0x9e3779b9 + (seed << 6) + (seed >> 2);
	}

	template<class... TupleArgs>
