◆ beginCOFFSymbolDef()

void llvm::RecordStreamer::beginCOFFSymbolDef ( const MCSymbol Symbol)
inlineoverridevirtual

Start emitting COFF symbol definition.

Parameters
Symbol- The symbol to have its External & Type fields set.

Definition at line 59 of file RecordStreamer.h.

◆ emitAssignment()

void RecordStreamer::emitAssignment ( MCSymbol Symbol,

Symbol- The symbol being assigned to.
Value- The value for the symbol.

Reimplemented from llvm::MCStreamer.
