using clang16 and performing build on the risc-v board getting next error:

/home/user/openjdk/jdk/src/hotspot/cpu/riscv/c1_LIRAssembler_riscv.cpp:1518:10: error: call to member function 'null_check' is ambiguous
      __ null_check(obj);
      ~~~^~~~~~~~~~

fast fix was to change caller site to __ null_check(obj, nullptr);
