- Small code model:
```
.foo:
# %bb.0: # %entry
lwz 3, L..C0(2) # @b ;; Use one instruction to
load b's address in the TOC. So only 2^16 bytes TOC range can be accessed
because of encoding limitation of `lwz` instruction.

.foo:
# %bb.0: # %entry
addis 3, L..C0@u(2)
lwz 3, L..C0@l(3) ;; Use two instructions to load b's address.
So that bigger TOC range can be accessed.
