Proof step 133 from proof compat-put (previous step)

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

User applied rule case distinction

And obtained the following new goals

Proof step 31:
compat(str, val, ty, st), compatrefs(str, st), compatstatic(str, st), compatmode(str, st) ⊦ compatmode(str, st[r -- mkfs(class, ty, fieldvar) ', val]), ty = void_type, mkfs(class, ty, fieldvar) ' = _length
Proof step 69:
compat(str, val, ty, st), compatrefs(str, st), compatstatic(str, st), compatmode(str, st) ⊦ compatstatic(str, st[r -- mkfs(class, ty, fieldvar) ', val]), ty = void_type, mkfs(class, ty, fieldvar) ' = _length
Proof step 132:
compat(str, val, ty, st), compatrefs(str, st), compatstatic(str, st), compatmode(str, st) ⊦ compatrefs(str, st[r -- mkfs(class, ty, fieldvar) ', val]), ty = void_type, mkfs(class, ty, fieldvar) ' = _length
