Proof step 18 from proof inv-get-gc-block (previous step)

# lpt = # avol, keyset(bin-heap(kar, m)) = gc-heap(lpt, log), bin-heap-inv(bin-heap(kar, m), lpt), buf-ro-rw-mode(isbuf, bleb, lpt, avol), bufs-log-only(bleb, log, lpt), freelist-cons(lpt, freelist), log-group-block(log, lpt), lpt-free-unref(lpt), lpt-leb-size(lpt), lpt-ram-flash(lpt, lpt0, log) ⊦ # kar = 0, m = 0, dups(log), kar[0].idx < # avol ∧ lpt[kar[0].idx].flags = LP_GROUP_NODES ∧ ¬ kar[0].idx ∈ log

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 19:
# lpt = # avol, lpt[kar[0].idx] = mklp(m0, m1, lpf, m2), keyset(bin-heap(kar, m)) = gc-heap(lpt, log), bin-heap-inv(bin-heap(kar, m), lpt), buf-ro-rw-mode(isbuf, bleb, lpt, avol), bufs-log-only(bleb, log, lpt), freelist-cons(lpt, freelist), log-group-block(log, lpt), lpt-free-unref(lpt), lpt-leb-size(lpt), lpt-ram-flash(lpt, lpt0, log) ⊦ # kar = 0, m = 0, dups(log), kar[0].idx < # avol ∧ lpf = LP_GROUP_NODES ∧ ¬ kar[0].idx ∈ log

Rule argument

spec: lprops name: elim seq: ⊦ ((m = lp.ref-size ∧ m0 = lp.size) ∧ lpf = lp.flags) ∧ m1 = lp.gcheapidx ↔ lp = mklp(m, m0, lpf, m1) subst: [lp, m, m0, lpf, m1] → [lpt[kar[0].idx], m, m0, lpf, m1]

Additional information

Used simplifier rules: ⊦ ((m = lp.ref-size ∧ m0 = lp.size) ∧ lpf = lp.flags) ∧ m1 = lp.gcheapidx ↔ lp = mklp(m, m0, lpf, m1); (elim) Used terms: lpt[kar[0].idx], m, m0, lpf, m1
