Proof step 22 from proof nosharing-forward (previous step)

st[jvmref -- sks0] = refval(r0), st[r -- _type] .type = mkclasstype(class), st[jvmref -- sks] = refval(r0), fits(jvmref, sks, st), fits(jvmref, sks0, st), validref(str, r, ty, st), fs ' ∈ instfields(class) ⊦ r = jvmref, sks0 = sks, sks0 = [], sks = [], r0 = jvmref, is_referencevalue(st[r -- fs '])

User applied rule structural induction

And obtained the following new goals

Proof step 21:
∀ st, sks0, r0, r, class, str, ty, fs. st[jvmref -- sks0] = refval(r0) ∧ st[r -- _type] .type = mkclasstype(class) ∧ st[jvmref -- sks1] = refval(r0) ∧ fits(jvmref, sks1, st) ∧ fits(jvmref, sks0, st) ∧ validref(str, r, ty, st) ∧ fs ' ∈ instfields(class) → r = jvmref ∨ sks0 = sks1 ∨ sks0 = [] ∨ sks1 = [] ∨ r0 = jvmref ∨ is_referencevalue(st[r -- fs ']), st[jvmref -- sks0] = refval(r0), st[r -- _type] .type = mkclasstype(class), st[jvmref -- (sk + sks1)] = refval(r0), fits(jvmref, sk + sks1, st), fits(jvmref, sks0, st), validref(str, r, ty, st), fs ' ∈ instfields(class) ⊦ r = jvmref, sks0 = sk + sks1, sks0 = [], sk + sks1 = [], r0 = jvmref, is_referencevalue(st[r -- fs '])
