Proof step 2 from proof restrict-add-subseteq-at (
previous step
)
iast0[adr] = ind, adr ∈ iast0, iast0 | (as ++ adr) ⊆ iast1 ⊦ iast1[adr] = iast0[adr]
Heuristic simplifier applied rule simplifier
And obtained the following new goals
Proof step 3
:
adr ∈ iast0, iast0 | (as ++ adr) ⊆ iast1 ⊦ iast1[adr] = iast0[adr]
Rule argument
