/* 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. */
