title: Can you add preprocessor directives in assembly?
body: <p>I would like to execute some assembly instructions based on a define from a header file.</p>
  
  <p>Let's say in <code>test.h</code> I have <code>#define DEBUG</code>. </p>
  
  <p>In <code>test.asm</code> I want to check somehow like <code>#ifdef DEBUG</code> do something...</p>
  
  <p>Is such thing possible? I was not able to find something helpful in the similar questions or online.</p>
