Proof step 23 from proof exactarray-put-02 (previous step)

exactarray(val, byte_type, i, st) ⊦ exactreftype(val, mkarraytype(byte_type), st[r0 -- j ', byteval(by)]) ∧ val .refval ≠ jvmref ∧ (val .refval -- _length) × intval(i) ∈ st[r0 -- j ', byteval(by)] ∧ is_arrayref(val .refval, i, st[r0 -- j ', byteval(by)])

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ val .refval = jvmref → ¬ exactarray(val, ty, i, st)
Proof step 22:
exactarray(val, byte_type, i, st) ⊦ val .refval = jvmref, is_arrayref(val .refval, i, st[r0 -- j ', byteval(by)]) ∧ st[val .refval -- _length] = intval(i) ∧ val .refval -- _length ∈ st ∧ exactreftype(val, mkarraytype(byte_type), st[r0 -- j ', byteval(by)])
