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

Protected Attributes inherited from llvm::MCSymbol
MCFragmentFragment = 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...
