示例1: code_gen
void n_func_call::code_gen(status& stat, std::ostream& out)
{
// first, save the current return address in preallocated space.
out << "\tsw\t$ra,-8($fp)\n";
// next, push argument registers/temp registers in use on the stack.
stat.push_registers(out);
// next, load arguments into registers/stack.
right->code_gen(stat, out);
// next, call the function
std::stringstream id;
left->print(id);
out << "\t.option pic0\n"; // pic = position independent code
out << "\tjal\t" << id.str() << "\n";
out << "\tnop\n";
out << "\t.option pic2\n"; // would I be honest if I said I knew what these meant? no.
// next, pop arguments 4+ off the stack.
stat.unlock_arg_registers(out);
// store return value in preallocated register:
/***ASSUMING INT RETURN!!!!****/
if (stat.get_register() >= 0)
out << "\tmove\t$t" << stat.get_register() << ",$v0\n";
// next, pop argument registers back off the stack.
stat.pop_registers(out);
// finally, reload return address.
out << "\tlw\t$ra,-8($fp)\n";
return;
