MCSymbol(const MCSymbolTableEntry *Name, bool isTemporary)

bool isCommon() const

Is this a 'common' symbol.

void modifyFlags(uint32_t Value, uint32_t Mask) const

Modify the flags via a mask.

unsigned IsPrivateExtern

Mach-O specific: This symbol is private extern.

StringRef getName() const

getName - Get the symbol name.

void setFlags(uint32_t Value) const

Set the (implementation defined) symbol flags.

uint32_t getFlags() const

Get the (implementation defined) symbol flags.

unsigned IsExternal

True if this symbol is visible outside this translation unit.

MaybeAlign getCommonAlignment() const

Return the alignment of a 'common' symbol.

bool isTemporary() const

isTemporary - Check if this is an assembler temporary symbol.

const MCExpr * Value

If non-null, the value for a variable symbol.

bool isUsedInReloc() const

Twine - A lightweight data structure for efficiently representing the concatenation of temporary valu...

This is an optimization pass for GlobalISel generic memory operations.

LLVM_ABI void report_fatal_error(Error Err, bool gen_crash_diag=true)

StringMapEntry< MCSymbolTableValue > MCSymbolTableEntry

MCContext stores MCSymbolTableValue in a string map (see MCSymbol::operator new).

unsigned Log2(Align A)

Returns the log2 of the alignment.

This struct is a compact representation of a valid (non-zero power of two) alignment.

constexpr uint64_t value() const

This is a hole in the type system and should not be abused.

This struct is a compact representation of a valid (power of two) or undefined (0) alignment.
