Proof step 15 from proof compat-put (previous step)

st[_mode] = throw(r0, ty0), is_subtype(str, ty0, mkclasstype(`java.lang.Throwable' .class)), compat(str, refval(r0), ty0, st), compat(str, val, ty, st), compatrefs(str, st), compatstatic(str, st), _mode ∈ st, compat(str, throw(r0, ty0) .val, ty0, st) ⊦ r0 = jvmref, ty = void_type, mkfs(class, ty, fieldvar) ' = _length, compat(str, refval(r0), ty0, st[r -- mkfs(class, ty, fieldvar) ', val])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 14:
⊦ compat(str, val, ty, st) ∧ fs .type ≠ void_type → compat(str, val, ty, st[r -- fs ', val0])

Rule argument

[crewrite-arg: compatval-put , F , [val0, fs, r, st, ty, val, str] → [val, mkfs(class, ty, fieldvar), r, st, ty0, refval(r0), str] ]
