Proof step 11 from proof getbar-onlyModified (previous step)

onlyModified(str, r, st, st0), okbytearray(r1, st), okbytearray(r, st) ⊦ r = r1, getbytearray(r1, st) = getbytearray(r1, st0), junkref(str, r0, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ getbytearray(r, st) = getbytearray(r, 0, st[r -- _length] .intval, st)
Proof step 10:
onlyModified(str, r, st, st0), okbytearray(r1, st), okbytearray(r, st) ⊦ r = r1, getbytearray(r1, 0, st[r1 -- _length] .intval, st) = getbytearray(r1, st0), junkref(str, r0, st)

Rule argument

[speclemmaarg: , getbytearray(r, st) = getbytearray(r, 0, st[r -- _length] .intval, st) ,[st, r] → [st, r1] ,F ,storearrays , ,getByteArray-all ]
