Proof step 32 from proof reffield-del (previous step)

fs = mkfs(class, ty, fieldvar), is_reftype(ty), fs ' ∈ instfields(st[r0 -- _type] .type .class), is_obj(r0, st) ⊦ r0 = r, has_reffield(r0, st -- r)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 31:
is_reftype(ty), mkfs(class, ty, fieldvar) ' ∈ instfields(st[r0 -- _type] .type .class), is_obj(r0, st) ⊦ r0 = r, has_reffield(r0, st -- r)
