/* The UnixWare assembler, and probably other 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). Look for FloatDR below. */
