Not in general, again. After optimizations they probably won't even
have a fixed memory address. For example on AArch64 that code might
become something like:

    main:
        mov w0, #10
        mov w1, #22
        bl foo
        ret

Where e and f only ever exist in registers.

In some cases you might get lucky and see that the Value used in the
call came from a load instruction, and then you could get its address
from that. But it's not something you can rely on for correctness.

Cheers.
