Proof step 17 from proof cyclic-addarray-this (previous step)

∃ refs. dups(refs) ∧ refs .first = r ∧ validrefs(str, refs, (addarray(r, ty, i, st)[r -- _type]) .type, addarray(r, ty, i, st)), newref(r, st) ⊦ r = jvmref

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 16:
newref(refs .first, st), dups(refs), validrefs(str, refs, mkarraytype(ty), addarray(refs .first, ty, i, st)) ⊦ refs .first = jvmref

Rule argument

[emptyarg]
