Additional Inherited Members

- Protected Types inherited from llvm::MCSymbol
enum  SymbolKind {
  SymbolKindUnset , SymbolKindCOFF , SymbolKindELF , SymbolKindGOFF ,
  SymbolKindMachO , SymbolKindWasm , SymbolKindXCOFF
}
 The kind of the symbol. More...
 
enum  Contents : uint8_t {
  SymContentsUnset , SymContentsOffset , SymContentsVariable , SymContentsCommon ,
  SymContentsTargetCommon
}
 A symbol can contain an Offset, or Value, or be Common, but never more than one of these. More...
 
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 StringMapEntry< bool > *NameEntry
 The name for a symbol.
 
- Protected Member Functions inherited from llvm::MCSymbol
 MCSymbol (SymbolKind Kind, const StringMapEntry< bool > *Name, bool isTemporary)
 
void * operator new (size_t s, const StringMapEntry< bool > *Name, MCContext &Ctx)
 
uint32_t getFlags () const
 Get the (implementation defined) symbol flags.
 
void setFlags (uint32_t Value) const
 Set the (implementation defined) symbol flags.
 
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 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 IsUsed: 1
 IsUsed - True if this symbol has been used.
 
unsigned IsRegistered: 1
 
unsigned IsExternal: 1
 True if this symbol is visible outside this translation unit.
 
unsigned IsPrivateExtern: 1
 This symbol is private extern.
 
unsigned IsWeakExternal: 1
 This symbol is weak external.
 
unsigned Kind: 3
 LLVM RTTI discriminator.
 
unsigned IsUsedInReloc: 1
 True if we have created a relocation that uses this symbol.
 
unsigned SymbolContents: 3
 This is actually a Contents enumerator, but is unsigned to avoid sign extension and achieve better bitpacking with MSVC.
 
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...
