Proof step 51 from proof hasSharing-put-byteval-01 (previous step)

st[r0 -- sks0] = refval(r1), (st[r -- mkfs(class, byte_type, fieldvar) ', byteval(by)][r0 -- sks]) = refval(r1), fits(r0, sks0, st), fits(r0, sks, st[r -- mkfs(class, byte_type, fieldvar) ', byteval(by)]), fits(r0, sks0, st[r -- mkfs(class, byte_type, fieldvar) ', byteval(by)]), is_bytevalue(st[r -- mkfs(class, byte_type, fieldvar) ']) ⊦ st[r0 -- sks] = refval(r1), sks0 = sks, sks0 = [], sks = [], r1 = jvmref, mkfs(class, byte_type, fieldvar) ' = _length, r = jvmref, junkref(str, r0, st)

And obtained the following new goals

Proof step 47:
⊦ ¬ junkref(str, r, st) ∧ fits(r, sks, st) ∧ is_bytevalue(st[r1 -- fs ']) → (st[r1 -- fs ', byteval(by)][r -- sks]) = st[r -- sks]
Proof step 50:
¬ (¬ junkref(str, r0, st) ∧ fits(r0, sks, st) ∧ is_bytevalue(st[r -- mkfs(class, byte_type, fieldvar) '])), st[r0 -- sks0] = refval(r1), (st[r -- mkfs(class, byte_type, fieldvar) ', byteval(by)][r0 -- sks]) = refval(r1), fits(r0, sks0, st), fits(r0, sks, st[r -- mkfs(class, byte_type, fieldvar) ', byteval(by)]), fits(r0, sks0, st[r -- mkfs(class, byte_type, fieldvar) ', byteval(by)]), is_bytevalue(st[r -- mkfs(class, byte_type, fieldvar) ']) ⊦ st[r0 -- sks] = refval(r1), sks0 = sks, sks0 = [], sks = [], r1 = jvmref, mkfs(class, byte_type, fieldvar) ' = _length, r = jvmref, junkref(str, r0, st)
