Hi Bernardo,

Attached is a patch to replace FP_REG with A6_REG as suggested by
Roman.


The m68k-*-amigaos target moves FP to A5 because A6 is often
reserved to invoke OS libraries through a jump table.

I know the Amiga port is unofficial, but we can easily
avoid making the life of Gunther Nikl harder.

Yup. That's why I'm defining FRAME_POINTER_REGNUM to be A6_REG, not FP_REG. It should be easy for Gunther Nikl to replace A6_REG with A5_REG.
