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

⊦ r = jvmref, compatobj(str, r, st[_mode, val]) ↔ compatobj(str, r, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ compatobj(str, r, st) ↔ is_classtype(st[r -- _type] .type) ∧ class+∃(str, st[r -- _type] .type .class) ∧ compatfields(str, r, instfields(st[r -- _type] .type .class), st)
Proof step 9:
⊦ r = jvmref, is_classtype((st[_mode, val][r -- _type]) .type) ∧ class+∃(str, (st[_mode, val][r -- _type]) .type .class) ∧ compatfields(str, r, instfields((st[_mode, val][r -- _type]) .type .class), st[_mode, val]) ↔ compatobj(str, r, st)

Rule argument

[crewrite-arg: obj-compat, F, [st, r, str] → [st[_mode, val], r, str]]
