Proof step 9 from proof getintarray-put-other-02 (previous step)

i < 0 ∨ st[r -- _length] .intval < i ⊦ getintarray(r, 0, st[r -- _length] .intval, st[r -- i ', val]) = getintarray(r, 0, st[r -- _length] .intval, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
⊦ j0 < i → getintarray(r, i, j, st[r -- j0 ', val]) = getintarray(r, i, j, st)
Proof step 8:
st[r -- _length] .intval < i, 0 ≤ i ⊦ getintarray(r, 0, st[r -- _length] .intval, st[r -- i ', val]) = getintarray(r, 0, st[r -- _length] .intval, st)

Rule argument
