Proof step 3 from proof validref-addarray-get-01 (previous step)

validref(str, r, ty, st), newref(r0, st) ⊦ getintarray(r, i, j, addarray(r0, ty, i0, st)) = getintarray(r, i, j, st), r0 = jvmref

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ r ≠ r0 → getintarray(r, i, j, addarray(r0, ty, i0, st)) = getintarray(r, i, j, st)
Proof step 2:
⊦ newref(r, st) → ¬ validref(str, r, ty, st)

Rule argument

[speclemmaarg: , r ≠ r0 → getintarray(r, i, j, addarray(r0, ty, i0, st)) = getintarray(r, i, j, st) ,[st, i0, ty, r0, j, i, r] → [st, i0, ty, r0, j, i, r] ,F ,addarray , ,addarray-getintarray-other-01 ]
