Proof step 35 from proof validref-putrkvs (previous step)

i ' .fs = mkfs(class, ty0, fieldvar), okval(refval(r1), st[r0 -- _type] .type .type), validref(str, r, ty, st), validvals(str, rkvs0, st), validref(str, r1, st[r0 -- _type] .type .type, st), ∀ str, r, ty, st. validref(str, r, ty, st) ∧ validvals(str, rkvs0, st) → validref(str, r, ty, st[rkvs0]) ⊦ r0 = jvmref, is_arraytype(st[r0 -- _type] .type), validref(str, r, ty, st[r0 -- i ', refval(r1)]), validref(str, r, ty, st[r0 -- i ', refval(r1)][rkvs0])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 34:
⊦ validref(str, r, ty, st) ∧ ¬ is_array(str, r0, st) → validref(str, r, ty, st[r0 -- i ', val])

Rule argument

[crewrite-arg: validref-put-badarrayindex , F , [val, i, r0, st, ty, r, str] → [refval(r1), i, r0, st, ty, r, str] ]
