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