Already mentioned by Mattias in last messages.

  p := @Myfunction; // we have to add this dummy variable ...


Sorry, but as I said -- and have been trying to explain by subject and by
last messages --: just any compiler option/keyword/directive to disable its
optimization in specific parts of the user (programmer) code, leaving them
untouchable, but not by cheating the compiler using ugly/dummy codes. A
good option would be ("*please_leave_my_asm_function_in_peace*" just to
make it comical):

*{$please_leave_my_asm_function_in_peace ON}*
procedure foo;
asm
  alert('leave me in peace, compiler!');
end;
*{$endif}*

that's all, the foo() would be available in the final application script
even enabling the full optimization of the compiler, cause the user code
would be kept as it is. This is possible in other languages by using
keywords (e.g: volatile), compiler annotations and/or pragmas/directives
(some tools allows special comments too).

best,
