The optimizations are not a part of a C++ proposal, clearly, since the standard does not make such statements. There is usually a requirement of at least one fairly efficient implementation, leaving it open for improvements, and that is what I indicated. The LLVM code is in C, so templates won't help there. They seem happy with what they have.   That is "their problem", they can create a C++ interpreter inside the compiler, if needed to create the resulting efficient code. Or hardcode the problem for any bit width from 1 to 4096 bits. Typically this functionality could be done in C with recursive function calls?
