Proof step 30 from proof hasSharing-put-byteval-01 (previous step)

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

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 29:
⊦ ¬ junkref(str, r, st) ∧ is_bytevalue(st[r1 -- fs ']) ∧ fits(r, sks, st[r1 -- fs ', byteval(by)]) → fits(r, sks, st)

Rule argument

[crewrite-arg: fits-put-05-stronger , F , [str, r, st, r1, fs, sks, by] → [str, r0, st, r, mkfs(class, byte_type, fieldvar), sks0, by] ]
