While reading through the config/m68k.h file, I read that if you set the compiler for, and I quote.... /* Optimize for 68040, but still allow execution on 68020 (-m68020-40 or -m68040). The 68040 will execute all 68030 and 68881/2 instructions, but some of them must be emulated in software by the OS. When TARGET_68040 is turned on, these instructions won't be used. This code will still run on a 68030 and 68881/2. */ #define TARGET_68040 (target_flags & 01400) ..... I should be able to use the binaries produced. Question #1: Is there any advantage in performance ( is it worth doing )? Question #2: Has anyone done this successfully? I only have the workstation at home so binary compatibility isn't a problem ( no other machines around).
