Here's an incredibly minimalistic example: int f(double x, int y) { return x * y; } int g(int x, int y) { return x * y; } These two functions differ by a single token, yet their assembly translations have only one common instruction, and this instruction is "ret": f: movapd xmm1, xmm0 pxor xmm0, xmm0 cvtsi2sd xmm0, edi mulsd xmm0, xmm1 cvttsd2si eax, xmm0 ret g: mov eax, edi imul eax, esi ret
