For code sections (I assume read-only), isn't the linker always able to
merge identical ones? What can the compiler do better than the linker?
The linker doesn't know what the code does. The compiler does.
Therefore, the compiler always can do a better job, as it can
correctly identify more things as doing the same thing.
