Proof step 2 from proof crash-neutral-allocate-gnd (previous step)

fi1 = fi0, ginval0 = ginval, ginval1 = ginval2, gstore1 = crash(gstore, gstore0, ginval, nx), gstore2 = gstore0, maxino = maxino0, nx0 = nx, syn, inv-journal(nx, gstore, gstore0, ginval), ri-inj(fi0), ri-inj(fi) ⊦ ⟨index_allocate_gnd#(fi, fi0, gstore0, maxino0, ginval2, syn; ginval, gstore, nx; err)⟩ ( syn ∧ ginval0 = ginval ∧ gstore1 = crash(gstore, gstore0, ginval, nx) ∧ gstore2 = gstore0 ∧ nx0 = nx ∧ maxino = maxino0 ∧ ginval1 = ginval2 ∧ fi1 = fi0)

And obtained the following new goals

Proof step 3:
ginval0 = ginval, gstore1 = crash(gstore, gstore0, ginval, nx), nx0 = nx, remove-refsize0(gstore0) = gstore0, elems nx ∩ ginval = ∅, dom gstore0 ∪ elems nx = dom gstore ∪ ginval, inv(gstore \ ginval), inv(gstore0), ri-inj(fi), ri-inj(fi0), ¬ dups(nx) ⊦ ⟨index_allocate_gnd#(fi, fi0, gstore0, maxino0, ginval2, true; ginval, gstore, nx; err)⟩ (ginval0 = ginval ∧ gstore1 = crash(gstore, gstore0, ginval, nx) ∧ nx0 = nx)

Additional information

Used simplifier rules: ⊦ inv-journal(nx, gstore, gstore0, ginval) ↔ inv(gstore \ ginval) ∧ inv(gstore0) ∧ elems nx ∩ ginval = ∅ ∧ ¬ dups(nx) ∧ dom gstore0 ∪ elems nx = dom gstore ∪ ginval ∧ remove-refsize0(gstore0) = gstore0; (s)
