  60 /* The SystemV/386 SVR3.2 assembler, and probably all AT&T derived
  61    ix86 Unix assemblers, generate floating point instructions with
  62    reversed source and destination registers in certain cases.
  63    Unfortunately, gcc and possibly many other programs use this
  64    reversed syntax, so we're stuck with it.
  65
  66    eg. `fsub %st(3),%st' results in st = st - st(3) as expected, but
  67    `fsub %st,%st(3)' results in st(3) = st - st(3), rather than
  68    the expected st(3) = st(3) - st
  69
  70    This happens with all the non-commutative arithmetic floating point
  71    operations with two register operands, where the source register is
  72    %st, and destination register is %st(i).
  73
  74    The affected opcode map is dceX, dcfX, deeX, defX.  */
