printPCRelImm()

static void printPCRelImm ( X86AsmPrinter &  P, const MachineInstr *  MI, unsigned  OpNo, raw_ostream &  O  )

static

printPCRelImm - This is used to print an immediate value that ends up being encoded as a pc-relative value.

These print slightly differently, for example, a $ is not emitted.

printSymbolOperand()

static void printSymbolOperand ( X86AsmPrinter &  P, const MachineOperand &  MO, raw_ostream &  O  )

static

printSymbolOperand - Print a raw symbol reference operand.

This handles jump tables, constant pools, global address and external symbols, all of which print to a label with various suffixes for relocation types etc.
