Proof step 30 from proof fits-put-stronger (previous step)

st[r -- sk] = refval(r0), is_obj(str, r, st), okarray(r1, byte_type, st), r1 ∈ st, fits(r0, sks0, st), is_classtype(st[r -- _type] .type), sk ∈ instfields(st[r -- _type] .type .class), ∀ r, st, r1, i, by, str. fits(r, sks0, st) ∧ okarray(r1, byte_type, st) ∧ r1 ∈ st → (st[r1 -- i ', byteval(by)][r -- sks0]) = st[r -- sks0] ∨ r1 = jvmref ∨ junkref(str, r, st) ⊦ r1 = jvmref, (st[r1 -- i ', byteval(by)][r -- (sk ' + sks0)]) = st[r -- (sk ' + sks0)], r = jvmref, junkref(str, r, st)

Proof step 29:
st[r -- _type] .type = mkclasstype(class), st[r -- sk] = refval(r0), is_obj(str, r, st), okarray(r1, byte_type, st), r1 ∈ st, fits(r0, sks0, st), is_classtype(st[r -- _type] .type), sk ∈ instfields(class), ∀ r, st, r1, i, by, str. fits(r, sks0, st) ∧ okarray(r1, byte_type, st) ∧ r1 ∈ st → (st[r1 -- i ', byteval(by)][r -- sks0]) = st[r -- sks0] ∨ r1 = jvmref ∨ junkref(str, r, st) ⊦ r1 = jvmref, (st[r1 -- i ', byteval(by)][r -- (sk ' + sks0)]) = st[r -- (sk ' + sks0)], r = jvmref, junkref(str, r, st)
