>Description:
This code produces incorrect assembly for ColdFire target:

void a() {
	extern unsigned long x;
	extern long long y;
	
	y = x;
}

The final error message being:
/tmp/ccsny1fk.s: Assembler messages:
/tmp/ccsny1fk.s:7: Error: operands mismatch -- statement `move.l x,y+4' ignored
>How-To-Repeat:
gcc -m5200 x.c

Where x contains the above function.
Level of optimisation doesn't seem to matter.
>Fix:
None investigated.
