Enum OverflowOp 

pub enum OverflowOp {
    Add,
    Sub,
    Mul,
}

Which arithmetic one of the overflow checking builtins does.

One node with an operation rather than three nodes, because everything around the arithmetic itself is the same for all three: the same rule picks the type it happens at, the same narrowing decides whether the answer fit, and the same store puts it where it was asked for.

Variants

Add

__builtin_add_overflow.

Sub

__builtin_sub_overflow.

Mul

__builtin_mul_overflow.
