Proof step 4 from proof at-other-34 (previous step)

jvmref -- mkfs(`java.lang.Object' .class, void_type, `out' .field) ' = r -- mkfs(class, int_type, fieldvar) ' ⊦ val = st[jvmref -- mkfs(`java.lang.Object' .class, void_type, `out' .field) ']

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ r -- sk = r0 -- sk0 ↔ r = r0 ∧ sk = sk0

Rule argument

[speclemmaarg: ,r -- sk = r0 -- sk0 ↔ r = r0 ∧ sk = sk0 ,[sk0, r0, sk, r] → [mkfs(class, int_type, fieldvar) ', r, mkfs(`java.lang.Object' .class, void_type, `out' .field) ', jvmref] ,F ,refkey , ,inj ]
