Managed to find
https://www.cs.auckland.ac.nz/references/macvax/indexed-address-mode.html
which seems to say
convert byte to long
src = 0x2 + r0 + [r0 * operand size]
dest = 0x15

The 0x15 amount makes more sense if I consider it's gcc -c output, so
it's going to be a real address after linking probably (?).
