Variants

Int(IntUnOp)

An operation on an integer; returns an integer of the same type.

Cast(CastOp)

A form of cast; the return type is given by the specific cast operation.

GetThinPointer

Returns a raw pointer with same thin pointer as the operand, but without the metadata.

GetMetadata

Returns the metadata of a pointer as a value. The return type is given by PointerMetaKind::ty(), e.g., for a thin pointer this is ().

ComputeSize(Type)

Returns the dynamic size of the type given the pointer metadata. The operand must be a matching metadata for the type. For sized types this is ().

ComputeAlign(Type)

Returns the dynamic alignment of the type given the pointer metadata. The operand must be a matching metadata for the type. For sized types this is ().

VTableMethodLookup(TraitMethodName)

Lookup the function pointer for a trait object method. The operand must be a pointer to a vtable as returned by Constant::VTablePointer. The parameter specifies which method of the vtable to look up.
