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 = union { const MCSymbolTableEntry *NameEntry
 The name for a symbol.
 
- Protected Member Functions inherited from llvm::MCSymbol
 MCSymbol (const MCSymbolTableEntry *Name, bool isTemporary)
 
 MCSymbol (const MCSymbol &)=default
 
MCSymboloperator= (const MCSymbol &)=delete
 
LLVM_ABI void * operator new (size_t s, const MCSymbolTableEntry *Name, MCContext &Ctx)

void modifyFlags (uint32_t Value, uint32_t Mask) const
 Modify the flags via a mask.
 
- 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...
 
   const MCExpr *   Value
 If non-null, the value for a variable symbol. More...
