resolve_symbol()

virtual optional< uint64_t > LIEF::assembly::AssemblerConfig::resolve_symbol ( const std::string & )

inlinevirtual

This function aims to be overloaded in order to resolve symbols used in the assembly listing.

For instance, given this assembly code:

0x1000: mov rdi, rbx
0x1003: call _my_function

The function _my_function will remain undefined unless we return its address in resolve_symbol():

class MyConfig : public AssemblerConfig {
  public:
  optional<uint64_t> resolve_symbol(const std::string& name) {
    if (name == "_my_function") {
      return 0x4000;
    }
    return nullopt(); // or AssemblerConfig::resolve_symbol(name)
  }
};
