And in fact on systems that use the MIPS chips (MIPSco, SGI, DECstation), the assemblers already do this, primarily to fill delay slots and such. If I really need to know about what the assembler did behind my back, I have to disassemble the object module. -- Michael Meissner email: meissner@osf.org phone: 617-621-8861 Open Software Foundation, 11 Cambridge Center, Cambridge, MA, 02142 Do apple growers tell their kids money doesn't grow on bushes?
