This isn't right. The NUMBER_OF_TYPES doesn't directly have to do
with the bit
you use, and I don't think there is an easy way to couple the two.
NUMBER_OF_TYPES is 2 but that's not a bit offset. There's also no
This should be:
class OperatorBits : public BitField<Token, 0, 8> {};
class StateEnumSetBits : public BitField<int, 8, 3> {};
And the rest of the code should use those.
I think the code is correct. The encoding of the state is an enum set,
which uses one bit per type, thus the NUMBER_OF_TYPES (=3) is indeed the
number of bits, the enum set uses. The operator is either minus or not,
thus i use just one bit to encode it. This operater bit comes after the
state, thus it has an offset of NUMBER_OF_TYPES to the left.
I didn't use the BitField class to store the operator, since i only ever
use 2 tokens of all the possible 8...

I only pulled this method up from the OptimizedGraphBuilder, and its
only used in this hierarchy.

Actually not, since i know the stub passes the constant as right
operand. But i should definitely not use betterLeftOperand, since that
might be the constant...
