Detailed Description

Represent one information held inside an operand bundle of an llvm.assume.

AttrKind is the property that holds. WasOn if not null is that Value for which AttrKind holds. ArgValue is optionally an argument of the attribute. For example if we know that P has an alignment of at least four:

• AttrKind will be Attribute::Alignment.
• WasOn will be P.
• ArgValue will be 4.
