Yes, I think it should work, if you also compile all the libraries with
the same option.
But I will not provide such libraries, because I think it is a nonsense
to provide binaries optimized for nothing when it is possible to produce
2 binaries each one fully optimized for 68000 or ColdFire.
If I understand it well ColdFire is upwards compatible from V2, and
according to the V2 manual: "Version 2 ColdFire user code
runs unchanged on 68020, 68030, 68040, and 68060 processors". User
code I guess is the code which doesn't use supervisor only
Yes, I think this is right. So software compiled with -mcpu=5200
(similar to the deprecated -m5200) should work with both 68020+ and
ColdFire, just like AHCC.
