Proof step 10 from proof validref-put-field (previous step)

fs = mkfs(class, ty1, fieldvar), fs ' ∈ instfields(st[r -- _type] .type .class), st[r0 -- _type] .type ≤ ty1, is_obj(r, st), validref(str, r, ty, st), validref(str, r0, ty0, st) ⊦ r0 = jvmref, validref(str, r, ty, st[r -- fs ', refval(r0)])

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 9:
mkfs(class, ty1, fieldvar) ' ∈ instfields(st[r -- _type] .type .class), st[r0 -- _type] .type ≤ ty1, is_obj(r, st), validref(str, r, ty, st), validref(str, r0, ty0, st) ⊦ r0 = jvmref, validref(str, r, ty, st[r -- mkfs(class, ty1, fieldvar) ', refval(r0)])
