Proof step 6 from proof inv-erase (previous step)

pebs[m] = mkpeb(buf, m0, false), m < # pebs, mtd-cons(pebs) ⊦ ⟪if m < # pebs ∧ ¬ pebs[m].bad then {fail_or_success#(; ; err); if err = ESUCCESS then pebs[m] := mkpeb(emptypeb, 0, pebs[m].bad)} else abort⟫ mtd-cons(pebs)

Heuristic symbolic execution applied rule if positive right

And obtained the following new goals

Proof step 7:
pebs[m] = mkpeb(buf, m0, false), m < # pebs, mtd-cons(pebs) ⊦ ⟪fail_or_success#(; ; err); if err = ESUCCESS then pebs[m] := mkpeb(emptypeb, 0, pebs[m].bad)⟫ mtd-cons(pebs)

Rule argument

pos: right 1

Additional information

Used simplifier rules: ⊦ mkpeb(buf, m, boolvar).bad ↔ boolvar; (s)
