WebApr 9, 2024 · To enable inlining, a compiler needs to know which function is actually called. If a function is called directly, it’s pretty much guaranteed that a compiler would try to inline it. If the call is indirect (via function pointer, or via a table of virtual functions), in the general case a compiler won’t be able to inline that.
