     The presence of an __asm block in a function disables automatic
     register variable storage. The presence of inline assembly code
     in a function inhibits the following optimizations for the entire
     function:
 
       ■ Removal of invariant code from loops (/Ol)
 
       ■ Global register allocation (/Oe)
 
       ■ Global optimizations and common subexpressions (/Og)
