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