/* 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. */
