Proof step 10 from proof addarray-negative (previous step)

r ≠ jvmref ∧ r -- _type ∈ addarray(r, ty, i, st) ∧ is_typevalue(addarray(r, ty, i, st)[r -- _type]) ∧ is_arraytype((addarray(r, ty, i, st)[r -- _type]) .type) ∧ okarray(r, (addarray(r, ty, i, st)[r -- _type]) .type .type, addarray(r, ty, i, st)), i < 0 ⊦

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ r -- _type ∈ addarray(r, ty, i, st)
Proof step 3:
⊦ (addarray(r, ty, i, st)[r -- _type]) = typeval(mkarraytype(ty))
Proof step 4:
⊦ r ∈ addarray(r, ty0, i, st)
Proof step 9:
okarray(r, ty, addarray(r, ty, i, st)), i < 0 ⊦ r = jvmref
