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.
#pragma once
inline int only_inline() { return 42; }
static int only_static() { return 42; }

| case <-time.After(time.Second): | |
| // do something | |
| } | |
| } | |
| // instead of busy loop | |
| for { |
