Proof step 62 from proof junkrefs-null-01 (conclusion)

⊦ junkrefs(str, refs + jvmref ' + refs0, ty, st) ↔ junkrefs(str, refs, ty, st)

User applied rule structural induction

And obtained the following new goals

Proof step 1:
⊦ ¬ junkrefs(str, jvmref ' + refs, ty, st)
Proof step 2:
⊦ ¬ junkrefs(str, [], ty, st)
Proof step 61:
∀ str, refs0, ty, st. junkrefs(str, acc + jvmref ' + refs0, ty, st) ↔ junkrefs(str, acc, ty, st) ⊦ junkrefs(str, (r + acc) + jvmref ' + refs0, ty, st) ↔ junkrefs(str, r + acc, ty, st)

Rule argument

[VARWITHVARSEQSARG : refs, ()]
