Proof step 25 from proof coerce-okval (previous step)

⊦ ty = abstract_type, okval(coerce(val, ty), ty)

User applied rule structural induction

And obtained the following new goals

Proof step 3:
⊦ coerce(val, boolean_type) = boolval(val .boolval)
Proof step 4:
⊦ okval(val, boolean_type) ↔ is_boolvalue(val)
Proof step 5:
⊦ coerce(val, int_type) = intval(val .intval)
Proof step 6:
⊦ okval(val, int_type) ↔ is_integervalue(val)
Proof step 7:
⊦ coerce(val, short_type) = shortval(val .shortval)
Proof step 8:
⊦ okval(val, short_type) ↔ is_shortvalue(val)
Proof step 9:
⊦ coerce(val, byte_type) = byteval(val .byteval)
Proof step 10:
⊦ okval(val, byte_type) ↔ is_bytevalue(val)
Proof step 11:
⊦ coerce(val, long_type) = longval(val .longval)
Proof step 12:
⊦ okval(val, long_type) ↔ is_longvalue(val)
Proof step 13:
⊦ coerce(val, float_type) = floatval(val .floatval)
Proof step 14:
⊦ okval(val, float_type) ↔ is_floatvalue(val)
Proof step 15:
⊦ coerce(val, double_type) = doubleval(val .doubleval)
Proof step 16:
⊦ okval(val, double_type) ↔ is_doublevalue(val)
Proof step 17:
⊦ coerce(val, char_type) = charval(val .charval)
Proof step 18:
⊦ okval(val, char_type) ↔ is_charvalue(val)
Proof step 19:
⊦ coerce(val, void_type) = refval(val .refval)
Proof step 20:
⊦ okval(refval(r), ty) ↔ ty = void_type ∨ is_reftype(ty)
Proof step 21:
⊦ coerce(val, mkclasstype(class)) = refval(val .refval)
Proof step 22:
⊦ okval(refval(r), ty) ↔ ty = void_type ∨ is_reftype(ty)
Proof step 23:
⊦ coerce(val, mkarraytype(ty)) = refval(val .refval)
Proof step 24:
⊦ okval(refval(r), ty) ↔ ty = void_type ∨ is_reftype(ty)
