/* Define macro used to output shift-double opcodes when the shift
   count is in %cl.  Some assemblers require %cl as an argument;
   some don't.  This macro controls what to do: by default, don't

   Note the trailing space is necessary in case the character
   that immediately follows the comment is '*'.  If this happens
   and the space is not there the assembler will interpret this
   as the start of a C-like slash-star comment and complain when
   there is no terminator.  */
