Proof step 41:
⊦ compat(str, val, ty, st) ∧ fs .type ≠ void_type → compat(str, val, ty, st[r -- fs ', val0])
Proof step 45:
¬ (compat(str, st[jvmref -- sk], ty0, st) ∧ mkfs(class, ty, fieldvar) .type ≠ void_type), sk .fs = mkfs(class1, ty0, fieldvar0), sk ∈ statfields(class0), compatmode(str, st), compatrefs(str, st), compat(str, val, ty, st), initdone(class0, st), compatfields(str, jvmref, statfields(class0), st), class∃(str, class0) ∨ interface∃(str, class0), jvmref ≠ r ∨ sk ≠ mkfs(class, ty, fieldvar) ' ⊦ mkfs(class, ty, fieldvar) ' = _length, ty = void_type, r -- mkfs(class, ty, fieldvar) ' = _uninit, jvmref = r ∧ sk = mkfs(class, ty, fieldvar) ', jvmref -- sk ∈ st ∧ ¬ is_indexkey(sk) ∧ compat(str, st[jvmref -- sk], ty0, st[r -- mkfs(class, ty, fieldvar) ', val])
Proof step 49:
