is_aligned() [2/2] auto is_aligned ( const volatile T_Type *  pointer, UST  alignment  ) -> bool inlinenoexcept Check if a passed pointer is aligned. Template Parameters T_Type The pointer type Parameters [in] pointer Pointer that should be checked [in] alignment Required alignment Returns true or false 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: is_aligned(void const volatile*, unsigned long): mov rax, rdi xor edx, edx div rsi test rdx, rdx sete al ret The output for the template version with 4 byte alignment looks like this: bool is_aligned<4ul>(void const volatile*): test dil, 3 sete al ret Note that it consists of less instructions and that the expensive div instruction is removed.
