示例1: encodeInstruction

void WebAssemblyMCCodeEmitter::encodeInstruction(
    const MCInst &MI, raw_ostream &OS, SmallVectorImpl<MCFixup> &Fixups,
    const MCSubtargetInfo &STI) const {
  // FIXME: This is not the real binary encoding. This is an extremely
  // over-simplified encoding where we just use uint64_t for everything. This
  // is a temporary measure.
  support::endian::Writer<support::little>(OS).write<uint64_t>(MI.getOpcode());
  const MCInstrDesc &Desc = MCII.get(MI.getOpcode());
  if (Desc.isVariadic())
    support::endian::Writer<support::little>(OS).write<uint64_t>(
        MI.getNumOperands() - Desc.NumOperands);
  for (unsigned i = 0, e = MI.getNumOperands(); i < e; ++i) {
    const MCOperand &MO = MI.getOperand(i);
    if (MO.isReg()) {
      support::endian::Writer<support::little>(OS).write<uint64_t>(MO.getReg());
    } else if (MO.isImm()) {
      support::endian::Writer<support::little>(OS).write<uint64_t>(MO.getImm());
    } else if (MO.isFPImm()) {
      support::endian::Writer<support::little>(OS).write<double>(MO.getFPImm());
    } else if (MO.isExpr()) {
      support::endian::Writer<support::little>(OS).write<uint64_t>(0);
      Fixups.push_back(MCFixup::create(
          (1 + MCII.get(MI.getOpcode()).isVariadic() + i) * sizeof(uint64_t),
          MO.getExpr(),
          STI.getTargetTriple().isArch64Bit() ? FK_Data_8 : FK_Data_4,
          MI.getLoc()));
      ++MCNumFixups;
    } else {
      llvm_unreachable("unexpected operand kind");
    }
  }

  ++MCNumEmitted; // Keep track of the # of mi's emitted.
