Detailed Description

Generic tagged DWARF-like metadata node.

An un-specialized DWARF-like metadata node. The first operand is a (possibly empty) null-separated MDString header that contains arbitrary fields. The remaining operands are dwarf_operands(), and are pointers to other metadata.

Uses the SubclassData32 Metadata slot.
