      Either of below will retain cla_func_to_retain():
      - Use below linker option:
        --undef_sym=cla_func_to_retain
      - Or place below in file.cla prior to definition of function cla_func_to_retain:
        NOTE: Cla1Prog is the output section for CLA code in linker cmd file:
        __asm("\t .retain "Cla1Prog:cla_func_to_retain"\n");

      The attached f1.c has these lines ...

      int main()
{
   return 0;
}

      The attached f2.cla has these lines ...

      __attribute__((retain))
void cla_function_not_called()
{
   __mdebugstop();
}

      Build it for EABI. Test for whether the CLA function is present.

      % cl2000 --abi=eabi --cla_support=cla2 f1.c
% cl2000 --abi=eabi --cla_support=cla2 f2.cla
% cl2000 -z f1.obj f2.obj -o test.out -c
<Linking>
% nm2000 test.out | findstr cla_function_not_called

      The retain function is not present.
