...er* inlining and constant propagation. It seems to me therefore that because of this we are missing optimization opportunities. Suppose the following example program: #include <cstdio> struct Base { virtual void foo() = 0; }; struct NothingDerived: Base { virtual void foo() {} }; struct PrintDerived: Base { virtual void foo() { printf("Hello World!"); } }; Base& select(int i) { static NothingDerived nd; static PrintDerived pd; if (i % 2 == 0) { return nd; } return pd; } int main() { Base& b = select(0); b.foo(); } Which gives the following main fun...
