Proof step 6 from proof inv-get-iblock-refsize (previous step)

# lpt = # avol, lpt[m] = mklp(m0, m1, LP_INDEX_NODES, m2), keyset(gch) = gc-heap(lpt, log), m < # avol, bin-heap-inv(gch, 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) ⊦ ⟪if m < # lpt ∧ lpt[m].flags = LP_INDEX_NODES then n := lpt[m].ref-size else abort⟫ true

Heuristic symbolic execution applied rule if positive right

And obtained the following new goals

Proof step 7:
# lpt = # avol, lpt[m] = mklp(m0, m1, LP_INDEX_NODES, m2), keyset(gch) = gc-heap(lpt, log), m < # avol, bin-heap-inv(gch, 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) ⊦ ⟪n := lpt[m].ref-size⟫ true

pos: right 1

Additional information

Used simplifier rules: ⊦ mklp(n2, n3, lpf, m).flags = lpf; (s)
