I think this is because difference in raw and pseudo register size.
The pseudo registers are of one byte and due to big endian we are getting
wrong byte.

It display <cooked> for CCR and print cooked-registers displays zero.

I will try but its going to take some time to understand the test framework.
Here is the C code which can be used for testing -
int main()
{
asm("mov #0x55, r0l");
asm("ldc r0l, ccr");
asm("stc ccr, r1l");
}
