[fpc-devel] Smart-linking on linux/x86-64

[Joost van der Sluis via fpc-devel]

Hi all,

I have a very small application, see below. One procedure is not called 
at all.

But when I compile with

ppcx64 -XX -CX testcfi.pp

The P$TESTCFI_$$_NEVERCALLES symbol is still in the executable.

On Windows (internal linker) this code is omitted from the executable, 
but not on Linux.

Does anyone know why?


Regards,

Joost.



program testcfi;

{$mode objfpc}

  procedure JoJo;
  begin
    writeln('Tadaa');
  end;

  procedure NeverCalled;
  begin
    writeln('NeverCalled');
  end;

  procedure NoStackFrame;
  begin
    JoJo;
  end;

begin
  NoStackFrame;
end.
