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). See FloatDR below. The affected opcode map is dceX, dcfX, deeX, defX. */ #ifndef SYSV386_COMPAT /* Set non-zero for broken, compatible instructions.
