Proof step 47 from proof isarray-put-array-badindex (previous step)

st[r0 -- _type] = typeval(ty0), ty0 = mkarraytype(ty), r0 ∈ st, is_typevalue(st[r0 -- _type]), r0 -- _type ∈ st, i < 0 ⊦ okarray(r0, ty, st[r -- i ', val]) ↔ okarray(r0, ty, st), r0 = jvmref

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 46:
st[r0 -- _type] = typeval(mkarraytype(ty)), i < 0, r0 -- _type ∈ st, r0 ∈ st ⊦ r0 = jvmref, okarray(r0, ty, st[r -- i ', val]) ↔ okarray(r0, ty, st)
