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 MCSymbolTableEntry *NameEntry |
The name for a symbol. | |

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 | 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 |
Mach-O specific: 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... | |
}; | |
uint64_t | AlignmentPadding |
