What about gcc? I'd like to test a binary compiled for Coldfire V2
(-m5200). Would this binary work in CPUs from 68020 to 060 and
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
