Of course m68020-60 use only FPU instructions avaible on 68881 and 68060 and 68040, there is no specific 68881 instruction (like sin cos...) used with this option.Hello1Yes, normal instructions like movep or 64bit division aren't used. However,since m68020-60 means "compile for 68020 and FPU" it uses all 68881 instructions. And here it comes -- m68060 doesn't use emulated floating point instrucions what m68020-60 does.Are you sure the full 68881 instruction set is used? I would think only the reduced instruction set is used (or is this not possible?).
