Proof step 10 from proof pathex-putshortfield (previous step)

is_shortvalue(st[r -- mkfs(class, short_type, fieldvar) ']), validrefs(str, r0 ' + refs0, mkclasstype(`java.lang.Object' .class), st[r -- mkfs(class, short_type, fieldvar) ', shortval(sho)]) ⊦ junkref(str, r0, st), path∃(str, r0, (r0 ' + refs0) .last, st)

Heuristic weak cut applied rule cut formula

And obtained the following new goals

Proof step 2:
⊦ path∃(str, r, r, st) ↔ r = jvmref ∨ r ≠ jvmref ∧ is_valid_ref(str, r, st)
Proof step 9:
is_shortvalue(st[r -- mkfs(class, short_type, fieldvar) ']), validrefs(str, r0 ' + refs0, mkclasstype(`java.lang.Object' .class), st[r -- mkfs(class, short_type, fieldvar) ', shortval(sho)]) ⊦ refs0 = [], junkref(str, r0, st), path∃(str, r0, (r0 ' + refs0) .last, st)

Rule argument

[fma-arg: refs0 = []]
