Proof step 23 from proof fits-put-short-02 (previous step)

st[r -- sk] = refval(r0), is_obj(str, r, st), is_shortvalue(st[r1 -- fs ']), fits(r0, sks0, st), is_classtype(st[r -- _type] .type), sk ∈ instfields(st[r -- _type] .type .class), r ≠ r1 ∨ _type ≠ fs ', junkref(str, r0, st) ∨ fits(r0, sks0, st[r1 -- fs ', shortval(sho)]) ⊦ r = jvmref, junkref(str, r, st), fits((st[r1 -- fs ', shortval(sho)][r -- sk]) .refval, sks0, st[r1 -- fs ', shortval(sho)]) ∧ is_referencevalue(st[r1 -- fs ', shortval(sho)][r -- sk])

Proof step 22:
st[r -- _type] .type = mkclasstype(class), st[r -- sk] = refval(r0), is_obj(str, r, st), is_shortvalue(st[r1 -- fs ']), fits(r0, sks0, st), is_classtype(st[r -- _type] .type), sk ∈ instfields(class), r ≠ r1 ∨ _type ≠ fs ', junkref(str, r0, st) ∨ fits(r0, sks0, st[r1 -- fs ', shortval(sho)]) ⊦ r = jvmref, junkref(str, r, st), fits((st[r1 -- fs ', shortval(sho)][r -- sk]) .refval, sks0, st[r1 -- fs ', shortval(sho)]) ∧ is_referencevalue(st[r1 -- fs ', shortval(sho)][r -- sk])
