Proof step 11 from proof validrefnotnull-put-byteval (previous step)

fs .type = byte_type, is_bytevalue(st[r -- fs ']), validrefnotnull(str, r0, ty, st) ⊦ fs ' = _type, fs ' = _length, r = jvmref, r0 = jvmref, validrefnotnull(str, r0, ty, st[r -- fs ', byteval(by)])

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 10:
fs = mkfs(class, ty0, fieldvar), ty0 = byte_type, is_bytevalue(st[r -- fs ']), validrefnotnull(str, r0, ty, st) ⊦ fs ' = _type, fs ' = _length, r = jvmref, r0 = jvmref, validrefnotnull(str, r0, ty, st[r -- fs ', byteval(by)])

Rule argument
