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. WebCS 4120 Introduction to Compilers 10 Structure of an optimization • Optimization is a code transformation • Applied at some stage of compiler (HIR, MIR, LIR) • In general, requires some analysis: –safety analysis to determine whether transformation might change meaning –cost analysis to determine whether expected to improve performance
