class MetadataAsValue

Declaration

class MetadataAsValue : public Value { /* full declaration omitted */ };

Description

Metadata wrapper in the Value hierarchy. A member of the \a Value hierarchy to represent a reference to metadata. This allows, e.g., intrinsics to have metadata as operands. Notably, this is the only thing in either hierarchy that is allowed to reference \a LocalAsMetadata.
