performance, we typically think about the function logic. We’ll see that a well designed function API can have an even larger impact.How will we compare performance? ● Benchmarks at this low level are 60 ret 0 I N T 50Itanium C++ ABI 3.1.3.1 Non-trivial Return Values If the return type is a class type that is non-trivial for the purposes of calls, the caller passes an address as an implicit parameter problem 51The problem Itanium C++ ABI 3.1.3.1 Non-trivial Return Values If the return type is a class type that is non-trivial for the purposes of calls, the caller passes an address as an implicit parameter
