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.
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
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).
74 The affected opcode map is dceX, dcfX, deeX, defX. */
