Proof step 7 from proof getbooleanarray-length (conclusion)

⊦ okarray(r, boolean_type, st) → st[r -- _length] .intval = n→i(# getbooleanarray(r, st))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ getbooleanarray(r, st) = getbooleanarray(r, 0, st[r -- _length] .intval, st)
Proof step 2:
⊦ getbooleanarray(r, i, j, st) = booleanvalues(getarray(r, i, j, st))
Proof step 6:
okarray(r, boolean_type, st), r ∈ st ⊦ st[r -- _length] .intval = n→i(# booleanvalues(getarray(r, 0, st[r -- _length] .intval, st))), r = jvmref

Rule argument

[emptyarg]
