Abstractions and working at a high-level is great, the compiler does a great job of crunching it down to size. The example given by the OP of the assembler output of function used to write a pin is a pathological one, as the C++ code was written to be maximally generic. If you just want something fast and simple like a basic port write or math function in my experience it makes little difference if you write the code in C or ASM; the compiler is so good that it's very hard to beat the ASM it generates in most circumstances.
