Disabling optimization in certain areas

[Luigi]

Hi all,

I am using CW for the 9S08AW32 processor.  I want copyright information to be part of the executable code as data.  So, I have an array of characters for copyright information declared as "const char Copyright[] = { "Copyright 2008 ... All rights reserved." };  The problem comes in when the compiler wants to optimize Copyright out since it is not used.  So, to get around the problem, I have a statement in main, "errorcode = Copyright[0];".  My question: is there a way to tell the compiler to NOT optimize out the Copyright variable without using the assignment I made above?  Thanks.

You can tell the linker to consider your object as "root" when building the dependency information. Add the following snippet to your .prm file to do that:

DEPENDENCY
  ROOT Copyright END
END

Alternatively, you can add an "ENTRIES" block to your .prm file:

ENTRIES
  Copyright
END

Thanks!  I will give those a try.  I know it's no big deal to just leave the assignment statement in there, but I thought there must be a cleaner way of doing it.  Appreciated.
