Tagged DWARF-like metadata node.

A metadata node with a DWARF tag (i.e., a constant named DW_TAG_*, defined in llvm/BinaryFormat/Dwarf.h). Called DINode because it's potentially used for non-DWARF output.

Uses the SubclassData16 Metadata slot.

Definition at line 135 of file DebugInfoMetadata.h.

◆ DIFlags

Debug info flags.

The three accessibility flags are mutually exclusive and rolled together in the first two bits.
