Proof step 10 from proof eqex-mode (previous step)

st0[_mode] = noval, eqex(st, st0, r), eqex(st0, st, r) ⊦ st[_mode] = noval, r = jvmref

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 4:
⊦ eqex(st, st0, r) ↔ st -- r = st0 -- r
Proof step 9:
st0[_mode] = noval, st -- r = st0 -- r, eqex(st0, st, r) ⊦ st[_mode] = noval, r = jvmref

Rule argument

[crewrite-arg: eqex, F, [r, st0, st] → [r, st0, st]]
