php - CI 3 operation for user auth w/out model file -


i've revised code after following tutorials, i'm still stuck , appreciate guidance on how fix using view , controller.

view: 

 <form name='checklogin' action='<?php echo base_url();?>/index.php/myform/checklogin' method='post'>   <input type="text" name='username' id='username' class="form-control" placeholder="username" style='height: 3em;'><br>   <input type="password" name='password' id='password' class="form-control" style='height: 3em;' placeholder="password" required><br>   <center><button class="btn draw-border" type="submit" >sign in</button></center>   <center><br><a href= "/ci/index.php/myform/<?php echo "userregistration";?>">register</a></center>  </form>

controller:

public function showlogin(){      $this->load->view('loginview');  }     // check login data   public function checklogin() {      $this->form_validation->set_rules('username', 'username', 'required');     $this->form_validation->set_rules('password', 'password', 'required|md5|callback_check_database');          if ($this->form_validation->run() == false) {             $this->load->view('loginview');         } else {             redirect("/myform/successmessage");         } }  public function check_database($user_password){     $user = $this->input->post('username');     $pass = $this->input->post('password');      $result = $this->user->login($user, $pass);      if ($result) {         $query = array();         foreach($result $row) {             $query = array(                 'id' => $row->id,                 'username' => $row->user_name             );         }         return true;     }     else {         $this->form_validation->set_message('check_database', 'invalid username or password');         return false;      }  }

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
