Proof step 36 from proof junkrefs-addobj (previous step)

junkrefs(str, r ' + acc, ty, addobj(r0, class, fis, st)), newref(r0, st), is_valid_ref(str, r, st), st[r -- _type] .type ≤ ty, ∀ str, ty, r0, class, fis, st. junkrefs(str, acc, ty, addobj(r0, class, fis, st)) ∧ newref(r0, st) → r0 = jvmref ∨ junkrefs(str, acc, ty, st) ⊦ r = jvmref, r0 = jvmref, junkrefs(str, r ' + acc, ty, st)

Proof step 35:
junkrefs(str, r ' + acc, ty, addobj(r0, class, fis, st)), newref(r0, st), is_valid_ref(str, r, st), st[r -- _type] .type ≤ ty, ∀ str, ty, r0, class, fis, st. junkrefs(str, acc, ty, addobj(r0, class, fis, st)) ∧ newref(r0, st) → r0 = jvmref ∨ junkrefs(str, acc, ty, st) ⊦ r = r0, r = jvmref, r0 = jvmref, junkrefs(str, r ' + acc, ty, st)

Rule argument

[fma-arg: r = r0]
