Proof step 36 from proof put-switch-primval-field-index (previous step)

st[r -- sks1] = refval(r1), st[r0 -- sks] = refval(r2), fits(r, sks1 + mkfs(class, ty, fieldvar) ' ', st), fits(r0, sks + i ' ', st), i ' ∈ sks1 ⊦ sks1 = [], (st[r2 -- i ', val0][r1 -- mkfs(class, ty, fieldvar) ', val]) = (st[r2 -- i ', val0][(st[r2 -- i ', val0][r -- sks1]) .refval -- mkfs(class, ty, fieldvar) ', val]), sks = [], junkref(str, r0, st), junkref(str, r, st), is_referencevalue(st[r0 -- (sks + i ' ')]), is_reftype(ty), is_referencevalue(val0), is_referencevalue(val), mkfs(class, ty, fieldvar) ' ∈ sks

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 19:
⊦ sks ≠ [] → st[r -- (sks + sk ')] = st[st[r -- sks] .refval -- sk]
Proof step 35:
sks ≠ [], st[r -- sks1] = refval(r1), st[r0 -- sks] = refval(r2), fits(r, sks1 + mkfs(class, ty, fieldvar) ' ', st), fits(r0, sks + i ' ', st), i ' ∈ sks1 ⊦ sks1 = [], (st[r2 -- i ', val0][r1 -- mkfs(class, ty, fieldvar) ', val]) = (st[r2 -- i ', val0][(st[r2 -- i ', val0][r -- sks1]) .refval -- mkfs(class, ty, fieldvar) ', val]), sks = [], junkref(str, r0, st), junkref(str, r, st), is_referencevalue(st[st[r0 -- sks] .refval -- i ']), is_reftype(ty), is_referencevalue(val0), is_referencevalue(val), mkfs(class, ty, fieldvar) ' ∈ sks
