def case_cmp(self):
 151         lst = ["subf. 1, 6, 7",
 152                "cmp cr2, 1, 6, 7"]
 153         initial_regs = [0] * 32
 154         initial_regs[6] = 0x10
 155         initial_regs[7] = 0x05

running test_caller_alu.py shows:
        e = ExpectedState(pc=8)
        e.intregs[1] = 0xfffffffffffffff5
        e.intregs[6] = 0x10
        e.intregs[7] = 0x5
        e.crregs[0] = 0x8
        e.crregs[2] = 0x4

for subf. 1, 6, 7
here gpr1 is 0xffff_ffff_ffff_fff5 lesser than 0 so cr0 BF 1000

for cmp cr2, 1, 6, 7
here gpr6 is 0x10 bigger than gpr7 0x5 so cr2 should be 0b010 instead of now
evaluated 0b100
