Which m68k variants does this support?

[ngbrown]

For example, I'm using the Freescale/NXP ColdFire 5234, and the gcc m68k package supports that with the -mcpu=5234 switch.

There are a number of other variants, and I'm wondering which ones has the m68k backend for llvm been considered for and secondarily, tested on.

Is there an existing document that mentions m68k variant support?
