Proof step 4 from proof buf-ro-rw-mode-write-lpt-other (previous step)

lpt[n, lp][bleb.leb] = mklp(m, m0, lpf, m1) ⊦ bleb.isbuf? → bleb.leb < # lpt ∧ (boolvar ∧ m0 = LEB_SIZE ∨ m0 = # avol[bleb.leb].data) ↔ bleb.isbuf? → bleb.leb < # lpt ∧ (boolvar ∧ lpt[bleb.leb].size = LEB_SIZE ∨ lpt[bleb.leb].size = # avol[bleb.leb].data), bleb = buffered(n)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 5:
lpt[n, lp][bleb.leb] = mklp(m, m0, lpf, m1), lpt[bleb.leb] = mklp(m2, m3, lpf0, m4) ⊦ bleb.isbuf? → bleb.leb < # lpt ∧ (boolvar ∧ m0 = LEB_SIZE ∨ m0 = # avol[bleb.leb].data) ↔ bleb.isbuf? → bleb.leb < # lpt ∧ (boolvar ∧ m3 = LEB_SIZE ∨ m3 = # avol[bleb.leb].data), bleb = buffered(n)

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[bleb.leb], m2, m3, lpf0, m4]

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[bleb.leb], m2, m3, lpf0, m4
