Proof step 51 from proof validrefs-putbyte (previous step)

refs0 .first = st[r0 -- i0 '] .refval, i0 < st[r0 -- _length] .intval, is_referencevalue(st[r0 -- i0 ']), validrefs(str, refs0, st[r0 -- _type] .type .type, st), is_array(str, r0, st), okbytearray(r, st), st[r0 -- _type] .type ≤ ty, 0 ≤ i0, 0 < st[r0 -- _length] .intval, ∀ by, i, ty, str, st, r, refs1. # refs1 < # (r0 ' + refs0) → (okbytearray(r, st) ∧ validrefs(str, refs1, ty, st) → validrefs(str, refs1, ty, st[r -- i ', byteval(by)])) ⊦ r0 = jvmref, validrefs(str, r0 ' + refs0, ty, st[r -- i ', byteval(by)])

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 50:
st[r0 -- i0 '] = refval(r1), refs0 .first = r1, i0 < st[r0 -- _length] .intval, is_referencevalue(st[r0 -- i0 ']), validrefs(str, refs0, st[r0 -- _type] .type .type, st), is_array(str, r0, st), okbytearray(r, st), st[r0 -- _type] .type ≤ ty, 0 ≤ i0, 0 < st[r0 -- _length] .intval, ∀ by, i, ty, str, st, r, refs1. # refs1 < # (r0 ' + refs0) → (okbytearray(r, st) ∧ validrefs(str, refs1, ty, st) → validrefs(str, refs1, ty, st[r -- i ', byteval(by)])) ⊦ r0 = jvmref, validrefs(str, r0 ' + refs0, ty, st[r -- i ', byteval(by)])
