Proof step 8 from proof inv-read-gnd (previous step)

remove-refsize0(gstore1) = gstore1, elems nx ∩ ginval2 = ∅, dom gstore1 ∪ elems nx = dom gstore2 ∪ ginval2, inv(gstore1), inv(gstore2 \ ginval2), ri-inj(fi1), ri-inj(fi2), @(m, m0, m1) ∈ gstore2, ¬ dups(nx), ¬ m ∈ ginval2 ⊦ ⟪fail_or_success#(; ; err); if err = ESUCCESS then gnd := gstore2[@(m, m0, m1)] else gnd := ?⟫ true

Heuristic unfold applied rule call right

And obtained the following new goals

Proof step 9:
remove-refsize0(gstore1) = gstore1, elems nx ∩ ginval2 = ∅, dom gstore1 ∪ elems nx = dom gstore2 ∪ ginval2, inv(gstore2 \ ginval2), inv(gstore1), ri-inj(fi2), ri-inj(fi1), @(m, m0, m1) ∈ gstore2 ⊦ ⟪choose err0 with ⌊err0⌋ ∨ err0 = ESUCCESS in err := err0; if err = ESUCCESS then gnd := gstore2[@(m, m0, m1)] else gnd := ?⟫ true, dups(nx), m ∈ ginval2

Rule argument

pos: right 1

Additional information

Used simplifier rules: fail_or_success#(; ; ERR) {choose ERR0 with ⌊ERR0⌋ ∨ ERR0 = ESUCCESS in ERR := ERR0};
