Proof step 24 from proof compat-put (previous step)

_mode ≠ r -- mkfs(class, ty, fieldvar) ', compat(str, val, ty, st), compatrefs(str, st), compatstatic(str, st), _mode ∈ st, compatmode(str, st[_mode], st) ⊦ ty = void_type, mkfs(class, ty, fieldvar) ' = _length, compatmode(str, st[_mode], st[r -- mkfs(class, ty, fieldvar) ', val])

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 23:
compat(str, val, ty, st), compatrefs(str, st), compatstatic(str, st), _mode ∈ st, compatmode(str, st[_mode], st) ⊦ ty = void_type, mkfs(class, ty, fieldvar) ' = _length, compatmode(str, st[_mode], st[r -- mkfs(class, ty, fieldvar) ', val])
