Proof step 61 from proof hasSharing-put-byteval-01 (previous step)

is_bytevalue(st[r -- mkfs(class, byte_type, fieldvar) ']), hasSharing(r0, st[r -- mkfs(class, byte_type, fieldvar) ', byteval(by)]) ⊦ r = jvmref, mkfs(class, byte_type, fieldvar) ' = _length, hasSharing(r0, st), junkref(str, r0, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 25:
⊦ hasSharing(r, st) ↔ (∃ sks1, sks2. fits(r, sks1, st) ∧ fits(r, sks2, st) ∧ sks1 ≠ sks2 ∧ sks1 ≠ [] ∧ sks2 ≠ [] ∧ st[r -- sks1] .refval ≠ jvmref ∧ st[r -- sks1] = st[r -- sks2])
Proof step 60:
is_bytevalue(st[r -- mkfs(class, byte_type, fieldvar) ']), hasSharing(r0, st[r -- mkfs(class, byte_type, fieldvar) ', byteval(by)]) ⊦ r = jvmref, mkfs(class, byte_type, fieldvar) ' = _length, ∃ sks1, sks2. fits(r0, sks1, st) ∧ fits(r0, sks2, st) ∧ sks1 ≠ sks2 ∧ sks1 ≠ [] ∧ sks2 ≠ [] ∧ st[r0 -- sks1] .refval ≠ jvmref ∧ st[r0 -- sks1] = st[r0 -- sks2], junkref(str, r0, st)

Rule argument

[crewrite-arg: hasSharing-def, F, [st, r] → [st, r0]]
