Additional Inherited Members
Protected Types inherited from llvm::MCSymbol
enum	Kind : uint8_t { Regular, Equated, Common }
enum	: unsigned { NumCommonAlignmentBits = 5 }
	The alignment of the symbol if it is 'common'. More...
enum	: unsigned { NumFlagsBits = 16 }
	The Flags field is used by object file implementations to store additional per symbol information which is not easily classified. More...
using	NameEntryStorageTy
	The name for a symbol.
Protected Member Functions inherited from llvm::MCSymbol
	MCSymbol (const MCSymbolTableEntry *Name, bool isTemporary)
	MCSymbol (const MCSymbol &)=default

Protected Attributes inherited from llvm::MCSymbol
MCFragment *	Fragment = nullptr
	If a symbol has a Fragment, the section is implied, so we only need one pointer.
unsigned	kind: 2
	The symbol kind.
unsigned	HasName: 1
	True if this symbol is named.
unsigned	IsTemporary: 1
	IsTemporary - True if this is an assembler temporary label, which typically does not survive in the .o file's symbol table.
unsigned	IsRedefinable: 1
	True if this symbol can be redefined.
unsigned	IsRegistered: 1
unsigned	IsExternal: 1
	True if this symbol is visible outside this translation unit.
unsigned	IsPrivateExtern: 1
	Mach-O specific: This symbol is private extern.
unsigned	IsWeakExternal: 1
	This symbol is weak external.
unsigned	IsUsedInReloc: 1
	True if we have created a relocation that uses this symbol.
unsigned	IsResolving: 1
	Used to detect cyclic dependency like a = a + 1 and a = b; b = a.
unsigned	CommonAlignLog2: NumCommonAlignmentBits
uint32_t	Flags: NumFlagsBits
uint32_t	Index = 0
	Index field, for use by the object file implementation.
union {
uint64_t Offset
	The offset to apply to the fragment address to form this symbol's value. More...
uint64_t CommonSize
	The size of the symbol, if it is 'common'. More...
const MCExpr * Value
	If non-null, the value for a variable symbol. More...
