Proof step 8 from proof validref-addarray (previous step)

newref(r1, st), st[r -- _type] .type ≤ ty1 ⊦ r1 = jvmref, r = jvmref, r = jvmref ∨ (addarray(r1, ty, vals, st)[r -- _type]) .type ≤ ty1 ∧ ¬ junkref(str, r, addarray(r1, ty, vals, st)), junkref(str, r, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 4:
⊦ ¬ junkref(str, r, st) ∧ newref(r0, st) → ¬ junkref(str, r, addarray(r0, ty0, vals, st))
Proof step 7:
newref(r1, st), st[r -- _type] .type ≤ ty1 ⊦ r1 = jvmref, r = jvmref, junkref(str, r, st), (addarray(r1, ty, vals, st)[r -- _type]) .type ≤ ty1
