Can GCC for ARM flag this as a warning: A != B;

Recently, I was doing a review of some of my code and I found two instances where I mistakenly typed != instead of |=.

I was of the opinion that GCC might issue a warning for a non-executable instruction as A != B;

I say non-executable because != is not an assignment operator but a logical operator.

Is there an option that can flag this type of dumb mistake?

I don't know how the code worked properly since I was setting some bits that controlled flash programming -- luckily I caught it.

Thanks
