Because the psABI doc (p. 3-15) seem to specify that the caller should make a
temp copy in its own frame instead of passing it in argument space.
Though I just noticed that the computed address is placed in `%sp+92`, which is
odd.
I think `__trunctfhf2` is declared as `_Float16 __trunctfhf2(long double a)`
which means that the address should live in %o0 instead, no? Lemme look into it.
