Problems

7.1

Why does a SPARC linker check for address overflow when relocating branch addresses, but not when doing the high and low parts of the addresses in a SETHI sequence?

7.2

In the MIPS example, a REFHI relocation item needs a following PAIR item, but a REFLO doesn’t. Why not?

---

7.3

References to symbols that are pseudo-registers and thread local storage are resolved as offsets from the start of the segment, while normal symbol references are resolved as absolute addresses. Why?

---

7.4

We said that a.out and COFF relocation doesn’t handle references like A-B where A and B are both global symbols. Can you come up with a way to fake it?
