Proof step 3 from proof inv-get-block-free-size (previous step)

ginval = ginval1, ginval0 = ginval2, gstore = gstore1, gstore0 = gstore2, istore = istore1, istore0 = istore2, btree-inv(rp, adr, istore2, istore1, zh, ri, fi), inv-index(istore2, istore1), inv-journal(nx, gstore2, gstore1, ginval2), inv-state(pstate, nx, gstore2, istore2, syn) ⊦ ⟪apersistence_get_block_free_size#(adr, istore0, istore, ginval0, gstore0, gstore, nx, maxino, ginval, pstate, syn; ; n)⟫ true

Heuristic unfold applied rule call right

And obtained the following new goals

Proof step 4:
ginval = ginval1, ginval0 = ginval2, gstore = gstore1, gstore0 = gstore2, istore = istore1, istore0 = istore2, btree-inv(rp, adr, istore2, istore1, zh, ri, fi), inv-index(istore2, istore1), inv-journal(nx, gstore2, gstore1, ginval2), inv-state(pstate, nx, gstore2, istore2, syn) ⊦ ⟪if pstate = unbuffered then n0 := 0 else choose n with n ≤ LEB_SIZE in n0 := n⟫ true

Rule argument

pos: right 1
