misalignment() [2/2] auto misalignment ( const volatile T_Type *  pointer, UST  alignment  ) -> UST inlinenoexcept Calculate the misalignment of a pointer. Template Parameters T_Type The pointer type Parameters [in] pointer Pointer that should be checked [in] alignment Required alignment Returns Misalignment of the pointer in bytes Remarks Use the template version if the required alignment is known at compile-time. It is usually faster. Clang 10 with -O3 generates the following assembly for this function: misalignment(void const volatile*, unsigned long): mov rax, rdi xor edx, edx div rsi mov rax, rdx ret The output for the template version with 4 byte alignment looks like this: unsigned long misalignment<4ul>(void const volatile*): mov rax, rdi and eax, 3 ret Note that it consists of less instructions and that the expensive div instruction is removed.
