Which compiler does this not?

Well, here is Keil (NOT my sourcecode)

VOID half_ms_pause (USHORT half_ms)
{
  USHORT index;

  
  while (half_ms--)
  {
    /* just waste time */
    for (index = 0; index < PAUSE_SCALE_FACTOR33; index++)
    {
    }
  }
  
}  /*- end half_ms_pause -*/



; FUNCTION _half_ms_pause (BEGIN)
?C0001:
      MOV     A,R7
      DEC     R7
      MOV     R2,AR6
