Proof step 32 from proof fsync-pages-err (previous step)

pcache[datakey(m, n)] = mkpentry(true, buf0), err = ESUCCESS, n * VFS_PAGE_SIZE < m2, datakey(m, n) ∈ pcache, err0 = ESUCCESS ∨ ⌊err0⌋ ⊦ [afs_writepage#(mkinode(m, md, boolvar, m0, m1, m2), n, pcache[datakey(m, n)].page, dirs; err, files; asynced1); if err = ESUCCESS then afs_check_commit#(dirs, files; err; asynced1); if err = ESUCCESS then {asynced := false; pcache_set_status#(m, n, asynced; err, pcache)}; n := n + 1] (err = ESUCCESS ∨ ⌊err⌋ )

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 33:
pcache[datakey(m, n)] = mkpentry(true, buf0), pcache[datakey(m, n)] = mkpentry(boolvar0, buf), err = ESUCCESS, n * VFS_PAGE_SIZE < m2, datakey(m, n) ∈ pcache, err0 = ESUCCESS ∨ ⌊err0⌋ ⊦ [afs_writepage#(mkinode(m, md, boolvar, m0, m1, m2), n, buf, dirs; err, files; asynced1); if err = ESUCCESS then afs_check_commit#(dirs, files; err; asynced1); if err = ESUCCESS then {asynced := false; pcache_set_status#(m, n, asynced; err, pcache)}; n := n + 1] (err = ESUCCESS ∨ ⌊err⌋ )

Rule argument

spec: pcache-entry name: elim seq: ⊦ (boolvar ↔ pe.dirty) ∧ buf = pe.page ↔ pe = mkpentry(boolvar, buf) subst: [pe, boolvar, buf] → [pcache[datakey(m, n)], boolvar0, buf]

Additional information

Used simplifier rules: ⊦ (boolvar ↔ pe.dirty) ∧ buf = pe.page ↔ pe = mkpentry(boolvar, buf); (elim) Used terms: pcache[datakey(m, n)], boolvar0, buf
