Proof step 14 from proof validrefnotnull-put-shortval (previous step)

is_shortvalue(st[r -- mkfs(class, short_type, fieldvar) ']), validrefnotnull(str, r0, ty, st) ⊦ r = jvmref, r0 = jvmref, validrefnotnull(str, r0, ty, st[r -- mkfs(class, short_type, fieldvar) ', shortval(sho)])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ validrefnotnull(str, r, ty, st) ↔ r ≠ jvmref ∧ validref(str, r, ty, st)
Proof step 13:
is_shortvalue(st[r -- mkfs(class, short_type, fieldvar) ']), validrefnotnull(str, r0, ty, st) ⊦ r = jvmref, r0 = jvmref, r0 ≠ jvmref ∧ validref(str, r0, ty, st[r -- mkfs(class, short_type, fieldvar) ', shortval(sho)])

Rule argument

[crewrite-arg: validrefnotnull-def , F , [st, ty, r, str] → [st[r -- mkfs(class, short_type, fieldvar) ', shortval(sho)], ty, r0, str] ]
