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.
Definition at line 130 of file DebugInfoMetadata.h.
enum llvm::DINode::DIFlags : uint32_t |
Debug info flags.
The three accessibility flags are mutually exclusive and rolled together in the first two bits.
